Why Baked Cajun Shrimp?
Here are just a few reasons this recipe has earned a permanent place in home kitchens:
1. Quick and Easy
From start to finish, the entire dish takes less than 30 minutes. You can have dinner on the table faster than ordering takeout.
2. Big on Flavor
The Cajun spice blend adds a smoky, spicy, and herbaceous kick that’s bold but not overpowering.
3. Healthy and Light
Shrimp is low in calories, high in protein, and rich in key nutrients like selenium, iodine, and vitamin B12. Baking instead of frying cuts down on unnecessary fats.
4. Minimal Cleanup
It’s a one-pan dish when baked on a foil-lined sheet tray—perfect for those busy nights when you want great food without a pile of dirty dishes.
Key Ingredients and Their Roles
Shrimp (1 pound, large, peeled and deveined)
Opt for fresh or thawed frozen shrimp. Larger shrimp are easier to cook evenly and have a meatier texture. Keeping the tails on adds visual appeal, but tail-off is great for bite-size eating.
Olive Oil (2 tablespoons)
This helps the seasoning adhere to the shrimp and promotes even roasting in the oven.
Cajun Seasoning (1 tablespoon)
The star of the dish. You can use a high-quality store-bought blend or make your own (recipe below). Cajun seasoning typically includes paprika, garlic powder, onion powder, cayenne pepper, black pepper, and dried herbs.
Smoked Paprika (1 teaspoon)
Adds a smoky undertone that elevates the dish and gives the shrimp a deeper flavor.
Garlic Powder and Onion Powder (½ tsp and ¼ tsp)
These reinforce the savory base of the Cajun spice profile and balance the heat with earthy depth.
Dried Thyme (¼ tsp)
A subtle herbaceous note that’s traditional in Southern spice mixes.
Salt and Black Pepper
Enhances overall flavor and balances the spices.
Lemon Juice (Juice of ½ lemon)
Provides brightness and acidity, cutting through the richness of the oil and seasoning.
Fresh Parsley (optional garnish)
Adds a touch of color and freshness at the end.
Homemade Cajun Seasoning
If you want full control over your flavor profile (and sodium content), making your own Cajun seasoning is a great option. Here’s a simple, balanced version:

-
1 tablespoon smoked paprika
-
1 tablespoon garlic powder
-
1 tablespoon onion powder
-
2 teaspoons dried oregano
-
2 teaspoons dried thyme
-
1 teaspoon cayenne pepper (adjust for spice)
-
1 teaspoon black pepper
-
1 teaspoon salt
Instructions:
Mix all ingredients and store in an airtight jar. This will last several months and can be used on shrimp, chicken, potatoes, rice, and more.
Step-by-Step Recipe: Baked Cajun Shrimp
Ingredients (Serves 4)
-
1 pound large shrimp, peeled and deveined
-
2 tablespoons olive oil
-
1 tablespoon Cajun seasoning
-
1 teaspoon smoked paprika
-
½ teaspoon garlic powder
-
¼ teaspoon onion powder
-
¼ teaspoon dried thyme
-
Salt and black pepper, to taste
-
Juice of ½ lemon
-
1 tablespoon chopped fresh parsley (optional)
Instructions
Step 1: Preheat the Oven
Preheat your oven to 400°F (200°C). Line a baking sheet with foil or parchment paper for easy cleanup.
Step 2: Prepare the Shrimp
If using frozen shrimp, ensure they are fully thawed and patted dry. This helps them roast instead of steam. Remove tails if desired.
Step 3: Season the Shrimp
Place the shrimp in a large bowl. Add olive oil, Cajun seasoning, smoked paprika, garlic powder, onion powder, thyme, lemon juice, salt, and pepper. Toss thoroughly until the shrimp are evenly coated.
Step 4: Bake
Arrange the shrimp in a single layer on the prepared baking sheet. Bake for 8–10 minutes, depending on size. Shrimp are done when pink, opaque, and curled into a loose “C” shape.
Step 5: Garnish and Serve
Remove from the oven and immediately sprinkle with chopped parsley. Serve hot.
