Alfredo Broccoli Chicken: What You Need to Know

There are plenty of ways to make Alfredo chicken and broccoli. Some recipes use chicken breasts, while others use leftover chicken or a store-bought rotisserie chicken. Fresh broccoli is delicious, but frozen broccoli makes this meal even faster.

This version uses rotisserie chicken because it’s my go-to when I want dinner on the table fast. A Costco rotisserie chicken or any grocery store rotisserie chicken will work well. Just remove the meat from the bones and tear it into bite-sized pieces.

The sauce is homemade, but it doesn’t require a lot of work. You simply saute the garlic in butter, melt in the cream cheese, add the half-and-half and broth, then stir in Parmesan cheese at the end. That’s it!

What Is the Difference Between Chicken Alfredo and Chicken Fettuccine?

Chicken Alfredo describes the chicken and the creamy Alfredo sauce. Chicken fettuccine usually refers to chicken served with fettuccine pasta, but the sauce can vary.

In other words, chicken fettuccine can be made with Alfredo sauce, tomato sauce, pesto, or another sauce. Fettuccine is the type of pasta, while Alfredo is the creamy sauce.

This chicken Alfredo recipe with broccoli uses fettuccine noodles, but you can use penne, bow ties, rotini, or any pasta you have in the pantry. The ridges and curves in shapes like penne and rotini hold onto the sauce really well.

Homemade Alfredo Sauce vs. Jarred Alfredo Sauce

Homemade Alfredo sauce has a fresher flavor and lets you control the amount of garlic, cheese, salt, and pepper. It also gives the finished dish a rich, creamy texture that works beautifully with chicken and broccoli.

Jarred Alfredo sauce is a helpful shortcut when you are in a hurry. You can use a favorite store-bought sauce with cooked chicken, broccoli, and pasta for an even faster meal. A chicken broccoli Alfredo recipe with jar sauce is a good option for busy nights, especially when you don’t have time to make the sauce from scratch.

The main difference is texture and flavor. Homemade sauce is usually richer and more freshly flavored, while jarred sauce is convenient and ready to use. Both options work. Use whichever one fits your day.

What Cheese Works Best in Alfredo Sauce?

Freshly grated Parmesan is my favorite cheese for Alfredo sauce, and it’s the only cheese used in this recipe. Parmesan melts into the sauce and adds a salty, nutty flavor.

For the smoothest sauce, grate the Parmesan yourself instead of using shelf-stable powdered Parmesan. Pre-shredded cheese can also be used, but it may not melt as evenly.

If you want to try something different, you can add a small amount of:

• Mozzarella
• Monterey Jack
• White cheddar
• Asiago cheese
• Romano cheese

Try not to add too much extra cheese at once. The sauce can become very thick, and some cheeses may make the texture stringy.

Ingredients

The full measurements and instructions are in the recipe card below.

For the Pasta and Filling

• Fettuccine noodles
• Rotisserie chicken
• Frozen broccoli florets
• Water

For the Alfredo Sauce

• Butter
• Fresh garlic
• Cream cheese
• Half-and-half
• Chicken broth
• Salt and black pepper
• Freshly grated Parmesan cheese
• Fresh parsley
• Extra Parmesan cheese, for serving

How to Make Chicken Broccoli Alfredo

1. Cook the Broccoli

Place the frozen broccoli florets in a microwave-safe bowl with 2 tablespoons of water. Cover the bowl loosely and microwave on high until the broccoli is crisp-tender.

Start checking the broccoli after 2 minutes. Microwave times vary, so the total cooking time depends on your microwave. The broccoli should be tender but not mushy.

Drain any extra water and set the broccoli aside.

2. Cook the Fettuccine

Prepare the fettuccine according to the package instructions. Try to cook the pasta while the sauce is coming together so the noodles are still warm when you are ready to combine everything.

Drain the pasta, but don’t rinse it. Rinsing removes the starch that helps the Alfredo sauce cling to the noodles.

3. Make the Sauce

Add the butter and minced garlic to a large saucepan over medium heat. Cook for 1 to 2 minutes, stirring often, until the garlic is fragrant.

Add the softened cream cheese, half-and-half, and chicken broth. Stir constantly until the cream cheese melts completely into the sauce.

Reduce the heat to low. Continue cooking and stirring for about 15 minutes, or until the sauce thickens. Keep the heat low so the sauce stays smooth.

Remove the pan from the heat and stir in the freshly grated Parmesan cheese. Season with salt and black pepper.

4. Combine Everything

Add the cooked fettuccine, rotisserie chicken, and steamed broccoli to a large serving bowl. Pour the Alfredo sauce over the top.

Gently toss until the pasta, chicken, and broccoli are coated with sauce. Finish with chopped parsley and more freshly grated Parmesan cheese.

Serve right away while the sauce is warm and creamy. Enjoy!

Tips for the Best Chicken Alfredo with Broccoli

• Bring the half-and-half to room temperature before adding it to the hot saucepan. This helps prevent the sauce from separating.
• Soften the cream cheese before you begin. It melts into the sauce much more easily.
• Keep the sauce over low heat once the dairy is added.
• Stir the sauce often while it thickens.
• Add the Parmesan after removing the pan from the heat for a smoother sauce.
• Cook the broccoli just until crisp-tender. Overcooked broccoli can become soft and watery.
• Use freshly grated Parmesan for the best texture.
• Toss the sauce with warm pasta so it coats the noodles evenly.
• If the finished sauce is too thick, add a splash of warm milk, half-and-half, or pasta water.

Why Did My Alfredo Sauce Curdle?

Alfredo sauce can curdle when the fat separates from the liquid. This usually happens when the sauce gets too hot, the dairy is added while it is very cold, or the sauce sits for too long.

If your sauce starts to look lumpy or separated, remove it from the heat and whisk it vigorously. A small splash of warm milk or half-and-half can also help bring the sauce back together.

To help prevent curdling, use room-temperature half-and-half, keep the heat low, and avoid boiling the sauce.

How Do I Thicken Alfredo Sauce?

The sauce will thicken as it cooks and cools. If it still seems too thin, let it simmer over low heat for a few more minutes while stirring.

You can also add more freshly grated Parmesan cheese. Add it a little at a time so the sauce doesn’t become too thick.

If you need another option, mix a small amount of cornstarch with cold water before stirring it into the sauce. Never add dry cornstarch directly to the hot sauce because it can leave lumps.

If the sauce becomes too thick, add a little warm milk, cream, or chicken broth until it reaches the consistency you like.

How Can I Add More Flavor?

This Alfredo sauce already has garlic, butter, Parmesan, and chicken broth, but you can add other flavors if you like.

Try one of these simple additions:

• A small pinch of nutmeg
• Sauteed mushrooms
• Cooked onions
• Crushed red pepper flakes
• Diced jalapeno
• Fresh basil
• Fresh parsley
• A little Italian seasoning
• Cooked bacon or pancetta

Nutmeg is strong, so start with the smallest pinch. It adds a warm flavor without making the sauce taste like dessert.

Chicken Options for Alfredo Chicken Broccoli

Rotisserie chicken is the fastest choice, but you can use other cooked chicken too.

Chicken breasts are a classic option. Cook them separately, then slice or shred the meat before adding it to the pasta. Cooked chicken thighs are also a great choice because they stay tender and have a little more flavor.

Leftover grilled chicken, baked chicken, or even turkey can work in this recipe. Make sure the meat is fully cooked before adding it to the sauce.

If you are making a chicken alfredo with frozen broccoli, there is no need to thaw the broccoli first. Steam it directly from frozen, drain it well, and add it to the finished pasta.

Easy Chicken and Broccoli Alfredo Sauce Variations

There are so many delicious ways to change up this broccoli and chicken Alfredo recipe.

Add More Vegetables

Saute mushrooms with the garlic, or stir in peas during the last few minutes of cooking. You can also add spinach, asparagus, bell peppers, or sun-dried tomatoes.

If you are looking for another simple vegetable side, try these roasted asparagus.

Add White Beans

Stir in a can of drained and rinsed white beans for extra protein, fiber, and creaminess. Cannellini beans and Great Northern beans both work well.

Make It Spicy

Add a pinch or two of crushed red pepper flakes, or stir in a finely diced jalapeno with the garlic.

Add Fresh Herbs

Fresh parsley is included in this recipe, but fresh basil, chives, or a little rosemary can also add great flavor.

Skip the Chicken

Leave out the chicken and add more vegetables instead. Broccoli, mushrooms, peas, and spinach make a satisfying meatless pasta dinner.

You can also serve the Alfredo sauce with fish, shrimp, or salmon.

Use It as a Pizza Sauce

The creamy sauce makes a fun pizza topping. Spread it over pizza dough and add chicken, broccoli, mozzarella, and Parmesan before baking.

Can I Make This Recipe Low Carb?

Yes. Skip the fettuccine and serve the chicken and broccoli Alfredo over cauliflower rice, zucchini noodles, spaghetti squash, or butternut squash noodles.

These easy butternut squash noodles are a tasty option when you want something lighter than pasta.

For a lower-carb sauce, use heavy cream instead of half-and-half. Keep in mind that the sauce will be richer and thicker.

Can I Make Chicken Alfredo and Broccoli Gluten-Free?

Yes. Use gluten-free pasta and check the labels on the chicken broth, cream cheese, and other ingredients to confirm that they are gluten-free.

Brown rice pasta, chickpea pasta, or gluten-free fettuccine can all work well. If you use cornstarch to thicken the sauce, make sure the package is labeled gluten-free.

To make this meal paleo, skip the pasta and serve the chicken and broccoli over cauliflower rice or zucchini noodles. The traditional cream cheese and Parmesan sauce would also need to be replaced with ingredients that fit your dietary needs.

Can I Use a Lighter Substitute for Half-and-Half?

You can replace the half-and-half with whole milk, evaporated milk, or a mixture of milk and heavy cream. The sauce may be a little thinner with milk.

Greek yogurt can also add creaminess, but it should be stirred in after the pan is removed from the heat. If Greek yogurt gets too hot, it can separate and become grainy.

For the best results, add a small amount of warm pasta water if the sauce needs thinning.

Is Alfredo Chicken Broccoli Weight Watchers Friendly?

This recipe is rich because it includes butter, cream cheese, half-and-half, and Parmesan cheese. It isn’t designed to be a low-point meal.

If you are looking for a lighter option, try this Weight Watchers Alfredo sauce. It doesn’t have the same rich texture as this version, but it is a good choice when you are watching points.

Serve it with these 2-ingredient breadsticks for a simple side.

What Can I Serve with Chicken Alfredo and Broccoli?

This meal is filling on its own because it includes pasta, chicken, and broccoli. Still, a few simple sides make it feel like a complete dinner.

Try serving it with:

• A green salad
• Garlic bread
• Breadsticks
• Roasted asparagus
• Steamed green beans
• Dinner rolls

These homemade dinner rolls with cinnamon butter are especially good with a creamy pasta dinner.

You can also skip the pasta and serve the Alfredo chicken broccoli over vegetables. For a fun appetizer, leave out the chicken and broccoli, then serve the Alfredo sauce as a dip with breadsticks or garlic bread.

Make-Ahead and Meal Prep Instructions

You can prepare the chicken, broccoli, and sauce a day ahead. Store each part in a separate airtight container in the refrigerator, then warm the sauce gently on the stove before combining everything.

Cooked pasta can also be stored in the refrigerator, but it may stick together as it cools. Toss it with a small amount of oil, or add it directly to the warm sauce and stir until the noodles separate.

When reheating a complete serving, use the microwave in short intervals and stir between each one. You can also reheat it in a saucepan over low heat.

Add a splash of milk, cream, chicken broth, or water if the sauce has thickened too much.

How to Store and Reheat Alfredo Sauce

Store leftover Alfredo sauce in an airtight container in the refrigerator for up to 5 days. The sauce will thicken as it cools.

To reheat refrigerated sauce, place it in a saucepan over low heat. Stir often and add a little milk or cream to loosen it.

You can freeze Alfredo sauce for 2 to 3 months. Allow it to thaw in the refrigerator overnight, then warm it slowly on the stove. The texture may change slightly after freezing because of the dairy, but whisking in a splash of cream or milk can help smooth it out.

For the best texture, freeze the sauce separately from the pasta. Pasta can become soft after thawing and reheating.

Common Problems and Easy Fixes

The Sauce Is Too Thin

Continue cooking it over low heat for a few minutes. Add Parmesan cheese a little at a time if needed.

The Sauce Is Too Thick

Whisk in warm milk, half-and-half, cream, or chicken broth until it loosens.

The Sauce Is Grainy

The heat may have been too high, or the cheese may have been added while the sauce was boiling. Remove the pan from the heat and whisk in a splash of warm dairy.

The Broccoli Is Watery

Drain the broccoli well before adding it to the pasta. Extra water can thin the sauce.

The Pasta Is Sticky

Don’t rinse the cooked pasta. Toss it with the sauce while it is still warm, and add a little pasta water if needed.

The Alfredo Tastes Bland

Add salt, black pepper, more Parmesan, or a little extra garlic. A pinch of Italian seasoning or red pepper flakes can also wake up the flavor.

Five-Ingredient Shortcut

Need dinner even faster? Use:

• Cooked chicken
• Frozen broccoli
• Fettuccine
• Jarred Alfredo sauce
• Parmesan cheese

Cook the pasta and broccoli, warm the jarred Alfredo sauce, then toss everything together with the chicken. Add Parmesan on top and serve.

This shortcut doesn’t have the same flavor as homemade Alfredo, but it is an easy chicken broccoli Alfredo recipe for a busy night.

Frequently Asked Questions

Does broccoli go well with chicken Alfredo?

Yes! Broccoli adds color, texture, and a fresh vegetable flavor to the rich Alfredo sauce. Cook it until crisp-tender so it doesn’t become mushy.

What pasta goes with Alfredo sauce?

Fettuccine is the classic choice because the wide noodles hold plenty of sauce. Penne, rotini, bow ties, and linguine also work well.

Can I make Alfredo in an Instant Pot?

Yes, but this recipe is written for the stovetop. An Instant Pot version needs different liquid amounts and cooking times because the pasta cooks in the pressure cooker.

Can I make this in a slow cooker?

You can keep the chicken and sauce warm in a slow cooker, but dairy-based Alfredo sauce can separate if it cooks too long. Add the cooked pasta near the end and use the warm setting instead of cooking it for several hours.

How long does homemade Alfredo sauce last?

Homemade Alfredo sauce lasts up to 5 days in the refrigerator when stored in an airtight container. Frozen sauce is best used within 2 to 3 months.

Can I make Alfredo without cream cheese?

Yes. You can leave out the cream cheese and make the sauce with butter, cream, and Parmesan cheese. The cream cheese in this recipe adds extra body and a smooth texture, but it isn’t the only way to make Alfredo sauce.

Can I make Alfredo without heavy cream?

Yes. This recipe uses half-and-half instead of heavy cream. You can also use whole milk or evaporated milk, though the sauce may be a little lighter and thinner.
