Preheat oven to 400°F and line a large rimmed baking sheet with parchment paper. Set aside.
Prepare the garlic shrimp seasoning by combining the olive oil, minced garlic, Dijon mustard, ground cumin, and grated Parmesan cheese in a large glass bowl. Season with salt and black pepper, to taste.
Add shrimp to the bowl and toss to combine. Transfer the seasoned shrimp to the prepared baking sheet and place in pre-heated oven to roast for 6 to 8 minutes, or until the shrimp are just firm and pink. Do not overcook.
