Ingredients

For the Cajun Spice Blend:

  • 2 tsp smoked paprika

  • 1 tsp garlic powder

  • 1 tsp onion powder

  • 1 tsp dried oregano

  • 1/2 tsp dried thyme

  • 1/2 tsp cayenne pepper (adjust to your heat preference)

  • 1/2 tsp freshly ground black pepper

  • 1/4 tsp salt (optional – the butter will add saltiness)

For the Shrimp:

  • 1.5 lbs (680g) large raw shrimp, peeled and deveined (tails on or off)

  • 3 tbsp unsalted butter, melted

  • 4 large garlic cloves, minced

  • 2 tbsp fresh lemon juice (about 1/2 a lemon)

  • 1 tbsp olive oil

  • 1 lemon, thinly sliced, for garnish

  • Fresh parsley, finely chopped, for garnish

Equipment

  • Rimmed baking sheet or large oven-safe skillet

  • Small mixing bowl

  • Large mixing bowl

Instructions

1. Prep & Preheat (5 minutes)

Preheat your oven to 400°F (200°C). This high heat is key for cooking the shrimp quickly and getting a slight caramelization on the spices. While the oven heats, pat the shrimp thoroughly dry with paper towels. This crucial step ensures the spices and butter cling to the shrimp instead of steaming them. If using frozen shrimp, ensure they are completely thawed and dried.

2. Make the Spice Blend (2 minutes)

In a small bowl, whisk together all the Cajun spice blend ingredients: smoked paprika, garlic powder, onion powder, oregano, thyme, cayenne, black pepper, and optional salt. Making your own blend allows you to control the salt and heat level, and the aroma is incredible!

3. Create the Garlic Butter Sauce (3 minutes)

In a large mixing bowl, combine the melted butter, minced garlic, fresh lemon juice, and olive oil. Whisk it together until it forms a cohesive, fragrant sauce.

4. Season the Shrimp (2 minutes)

Add the dried shrimp to the large bowl with the garlic butter sauce. Toss gently until every shrimp is lightly coated. Then, sprinkle the homemade Cajun spice blend over the shrimp. Toss again, ensuring an even, vibrant coating on each piece.

5. Bake to Perfection (12-15 minutes)

Arrange the shrimp in a single layer on your rimmed baking sheet or oven-safe skillet. Scatter a few lemon slices over the top for extra aroma. Place the pan in the preheated oven and bake for 12-15 minutes. The shrimp are done when they are opaque, pink, and curled into a loose “C” shape. Be careful not to overcook, or they will become rubbery. The butter sauce will be bubbling and fragrant.

6. Serve Immediately (2 minutes)

Remove the pan from the oven. Garnish generously with freshly chopped parsley. For the full experience, serve directly from the pan at the table.

Serving Suggestions

  • Over Grains: Spoon the shrimp and all the glorious sauce over a bed of steamed white rice, quinoa, or creamy grits.

  • With Bread: Serve with a warm, crusty baguette or toasted ciabatta to mop up the incredible garlic-Cajun butter sauce.

  • As an Appetizer: Serve in a bowl with toothpicks for a crowd-pleasing starter.

  • Low-Carb Style: Pair with cauliflower rice or a simple green salad dressed with lemon vinaigrette.

Recipe Notes & Tips

  • Spice Level: This recipe has a medium kick. For milder shrimp, reduce the cayenne to 1/4 tsp or omit it. For extra heat, add 1/4-1/2 tsp of red pepper flakes to the spice blend.

  • Fresh vs. Frozen Shrimp: Either works perfectly! Just ensure frozen shrimp are fully thawed (in the fridge overnight or under cold running water) and thoroughly dried.

  • Avoid Overcrowding: Shrimp must be in a single layer. If they’re piled on top of each other, they’ll steam instead of roast. Use two pans if necessary.

  • Butter Alternative: For a dairy-free version, use a high-quality plant-based butter or all olive oil.
