Blackened Shrimp Ingredients
For the Blackening Seasoning
• Smoked Paprika – Adds warmth and depth to the seasoning; regular paprika can be used for a milder flavor.
• Chili Powder – Provides heat; substitute with cayenne pepper if you prefer an extra kick.
• Italian Seasoning – Blends various herbs for an aromatic touch; individual dried herbs like oregano and basil can work too.
• Garlic Powder – Enhances flavor; fresh minced garlic can be used for a stronger taste.
• Red Pepper Flakes – Adds a spicy kick; simply leave out for a milder dish.
• Salt – Enhances overall flavor; sea salt or kosher salt are great substitutions.
For the Shrimp
• Raw Shrimp (1.5 lb, large) – The star of the dish; deveined and peeled shrimp delivers the best flavor when fresh, but frozen shrimp works if properly thawed.
• Olive Oil (2 tbsp, divided) – Provides flavor and helps create that lovely blackened crust; avocado oil is an excellent alternative for higher smoke points.
For Garnishing
• Lemon Slices – Adds a fresh zing to your dish; optional but highly recommended.
• Chopped Fresh Basil or Parsley – Elevates presentation and freshness; feel free to use any fresh herb you love.
This Blackened Shrimp recipe promises a delightful experience—you won’t be able to resist that spicy, aromatic crust!
Step‑by‑Step Instructions for Blackened Shrimp
Step 1: Prepare the Blackening Seasoning
In a large bowl, combine 2 tablespoons of smoked paprika, 1 tablespoon of chili powder, 1 tablespoon of Italian seasoning, 1 teaspoon of garlic powder, 1 teaspoon of red pepper flakes, and 1 teaspoon of salt. Whisk these spices together until evenly mixed. Next, add the raw shrimp (1.5 lb, deveined and peeled) to the bowl along with 1 tablespoon of olive oil. Toss the shrimp until they are well-coated with the seasoning mixture.
Step 2: Heat the Skillet
Preheat a 12-inch cast-iron skillet over medium heat for about 3-4 minutes. Once the skillet is heated, increase the temperature to medium-high and add the remaining tablespoon of olive oil, swirling it to cover the pan’s surface. Look for the oil to shimmer, which indicates it’s ready for cooking. This ensures that the shrimp gets a beautifully charred crust when cooked.
Step 3: Cook the Shrimp
Add the seasoned shrimp to the hot skillet in a single layer, being careful not to overcrowd the pan. Cook the shrimp for approximately 2 minutes on one side, until they develop a deep blackened crust. Then, gently flip each shrimp and cook for another 1-2 minutes. The shrimp should turn pink and opaque, indicating they are perfectly cooked and full of flavor.
Step 4: Garnish and Serve
Once the shrimp are cooked through, immediately remove them from the heat to prevent overcooking. Transfer the blackened shrimp to a serving platter and garnish with fresh lemon slices and chopped basil or parsley for added brightness. Serve immediately alongside your favorite low-carb sides, and enjoy this delicious Blackened Shrimp dish!

Make Ahead Options
These Blackened Shrimp are perfect for busy home cooks looking to save time during hectic weeknights! You can prepare the blackening seasoning and coat the shrimp up to 24 hours in advance. Simply combine the spices in a bowl, toss the shrimp with 1 tablespoon of olive oil, and store them in an airtight container in the refrigerator. This allows the flavors to meld beautifully while ensuring the shrimp remain fresh. When you’re ready to serve, simply heat a cast-iron skillet and follow the cooking instructions as normal. This way, you can enjoy that delicious, spicy crust with minimal effort, making dinner a delightful experience!
