Ingredients & Substitutions

Before we get to the step by step instructions, a few notes about the ingredients:

• Shrimp: Large shrimp are ideal for this recipe. If using smaller shrimp, just decrease cook time (though this will make it more difficult to get a great blackened crust before the shrimp overcook.)
• Butter: An essential ingredient in any blackening recipe. The milk solids in the butter create the "blackening" effect on the shrimp and add rich flavor. If necessary, swap with avocado oil or ghee for a different flavor or to make it dairy-free.
• Blackening Seasoning: Store-bought is fine, but the homemade spice mix provided here is fresh, customizable, and easy to make.
• Lemon or Lime: Adds a bright, citrusy finish. Lime pairs beautifully with mango salsa, while lemon complements tartar sauce or garlic butter.

How to Make Blackened Shrimp

Step 1: Make Blackening Seasoning (if using store-bought, skip this step!)

Combine all herbs and spices in a bowl. Measure out 2 tablespoons of the spice mix to use for your shrimp recipe.

Step 2: Prep Shrimp

Dry shrimp very well with paper towels. Toss in melted butter, then in the spice mix to coat thoroughly. Preheat cast iron skillet over medium-high heat.

Step 3: Cook Shrimp and Serve!

Add seasoned shrimp to hot skillet in single layer, along with any seasoned butter stuck on your dish. Leave shrimp undisturbed for about 3 minutes, until a deep brown crust forms. Flip and cook just until opaque.

Serve with citrus wedges and tartar sauce, or with mango salsa.

Can I use frozen shrimp for this recipe?

Yes, you can use previously frozen shrimp! Just make sure to thaw them completely by letting them sit in the fridge overnight, or, if you're short on time, soak the sealed package of shrimp in cold water for 20-30 minutes. Dry shrimp thoroughly before seasoning to ensure they blacken properly.

Can I blacken shrimp without a cast iron skillet?

While cast iron is best for achieving a smoky char, any heavy-bottomed skillet or non-stick pan will work. Just preheat it well before adding the shrimp.

How do I know when the shrimp are done?

Shrimp are fully cooked when they turn opaque and curl into a loose "C" shape. Overcooked shrimp will form a tight "O" shape and can become rubbery.

Why isn't my crust getting dark enough? 

The key is making sure your pan is properly heated before adding the shrimp. Give your cast iron at least 4 minutes to heat up over medium-high heat. Also, ensure your shrimp are thoroughly dried before coating with butter and seasonings.

Can I make the blackening seasoning in advance?

Absolutely! I keep a rotating batch in my spice drawer for all my blackened seafood needs. Prepare a batch and store it in an airtight container or spice jar for up to 6 months. It’s great on any seafood, meat, roasted veggies, and even fries!
