Introduction
Bold, smoky, and just a little spicy, this blackened shrimp recipe delivers serious flavor in almost no time at all. Shrimp gets coated in a punchy blend of blackening spices, seared in a screaming-hot skillet until deeply charred, then finished with a rich garlic herb butter that melts right over the top and mellows out the heat.
I love this one because it hits so many notes at once — smoky, spicy, buttery, and fresh, all in a single bite. The blackening spice does most of the heavy lifting here, and the garlic herb butter at the end takes it from “really good” to “why haven’t I been making this every week.”
Serve it over rice, alongside grits for a true Southern-inspired plate, or tossed into tacos or a salad. However you serve it, this blackened shrimp with garlic herb butter comes together in about 15 minutes and packs way more flavor than that short cook time would suggest.

Ingredient Notes
Blackening seasoning is a blend of paprika, cayenne, garlic powder, onion powder, and dried herbs, and while store-bought blends work well, making your own at home lets you control the heat level exactly to your taste. Smoked paprika in particular adds a depth that regular paprika doesn’t quite match, so it’s worth using if you have it.
A screaming-hot, well-seasoned cast iron skillet is really what makes “blackened” happen — the intense, direct heat chars the spice coating quickly without overcooking the shrimp underneath. If you don’t have cast iron, any heavy-bottomed skillet that holds heat well will work, just make sure it’s fully preheated before adding the shrimp.
The garlic herb butter comes together in the same pan right after the shrimp, picking up all those flavorful blackened bits left behind. Fresh herbs like parsley or chives are ideal here, though a pinch of dried herbs will work in a pinch if that’s what you have available.
🔥 Blackened Shrimp with Garlic Herb Butter Recipe
Prep Time: 10 minutes | Cook Time: 8–10 minutes | Total Time: about 20 minutes Servings: 4
Ingredients
For the Blackened Shrimp:
- 1.5 lbs large shrimp, peeled and deveined
- 1 tbsp olive oil
- 2 tsp smoked paprika
- 1 tsp garlic powder
- 1 tsp onion powder
- 1 tsp dried oregano
- 1 tsp dried thyme
- 1/2 tsp cayenne pepper (adjust to taste)
- 1/2 tsp salt
- 1/4 tsp black pepper
For the Garlic Herb Butter:
- 4 tbsp unsalted butter
- 4 cloves garlic, minced
- 2 tbsp chopped fresh parsley
- 1 tbsp chopped fresh chives (or extra parsley)
- 1 tbsp fresh lemon juice
- Pinch of salt
For Serving:
- Cooked rice, grits, or crusty bread
- Extra lemon wedges
Instructions
Step 1: Make the blackening seasoning. In a small bowl, combine the smoked paprika, garlic powder, onion powder, oregano, thyme, cayenne, salt, and pepper, stirring well to distribute evenly. This blend can be made ahead and stored in an airtight container for future use.
Step 2: Coat the shrimp. Pat the shrimp completely dry with paper towels, then toss with olive oil and the blackening seasoning until every piece is evenly coated. Tip: pat the shrimp dry before adding the oil and seasoning — any leftover moisture will steam the shrimp instead of letting the spice coating char properly.
Step 3: Preheat the skillet. Heat a cast iron or other heavy-bottomed skillet over medium-high to high heat until very hot, about 3–4 minutes. A properly preheated pan is essential here, since the whole point of “blackening” is a quick, intense sear that chars the spices without overcooking the shrimp.
Step 4: Sear the shrimp. Add the shrimp to the hot, dry skillet in a single layer, being careful not to overcrowd the pan. Cook for about 1–2 minutes per side, until the spice coating is deeply charred in spots and the shrimp is pink and opaque throughout. Tip: expect some smoke during this step — that’s normal and part of what gives blackened dishes their signature charred flavor, so turn on your exhaust fan or crack a window if needed.
Step 5: Remove the shrimp. Transfer the blackened shrimp to a plate and set aside. Don’t wipe out the skillet — those charred bits left behind will add extra flavor to the garlic herb butter.
Step 6: Make the garlic herb butter. Reduce the heat to medium-low and add the butter to the same skillet. Once melted, add the minced garlic and cook for about 30 seconds, stirring constantly, just until fragrant. Tip: keep the heat low here — garlic burns quickly, and burnt garlic will turn the whole butter bitter instead of fragrant.
Step 7: Add the herbs and lemon. Stir in the chopped parsley, chives, lemon juice, and a pinch of salt, letting the butter bubble gently for about 30 seconds to bring everything together into a fragrant, glossy sauce.
Step 8: Return the shrimp and serve. Add the blackened shrimp back into the skillet, tossing gently to coat everything in the garlic herb butter. Serve immediately over rice, grits, or with crusty bread, with extra lemon wedges on the side.
Recipe Notes
- If your smoke alarm is sensitive, consider searing the shrimp outdoors on a grill griddle or opening windows and doors before starting.
- Double the blackening seasoning blend and store the extra in an airtight container for quick seasoning on chicken or fish another night.
- For a milder version, reduce the cayenne to 1/4 teaspoon or omit it entirely, relying on the smoked paprika for flavor without much heat.

Storage & Reheating
Leftovers will keep in an airtight container in the fridge for up to 2 days. Reheat gently in a skillet over low heat for a couple of minutes, being careful not to overheat, since shrimp can quickly turn tough when reheated too aggressively.
This dish isn’t a great candidate for freezing once cooked, since the butter sauce can separate and the shrimp’s texture suffers after thawing. If you’d like to prep ahead, the blackening seasoning blend can be made well in advance and stored at room temperature for weeks.
Budget Note
This recipe runs about $4–5 per serving, with shrimp being the main cost driver. To keep it more budget-friendly, buy frozen shrimp in bulk bags rather than fresh from the seafood counter, and make your own blackening seasoning from spices you likely already have rather than buying a premade blend.
Variations
Healthier/Lighter Version: Reduce the butter to 2 tablespoons and add a splash of olive oil in its place to lighten the finishing sauce while still keeping plenty of garlicky flavor. The blackened shrimp itself is already quite lean, so this swap mostly trims fat from the butter finish.
Keto/Low-Carb Version: This recipe is naturally low-carb as written, especially when served over cauliflower rice or a simple side of sautéed greens instead of regular rice or grits. Just double-check your blackening seasoning blend for any added sugar if using a store-bought version.
Grilled Version: Thread the seasoned shrimp onto skewers and grill over high heat for about 2 minutes per side, until charred and cooked through, then toss with the garlic herb butter made separately on the stovetop. This adds a smoky, outdoor-cooked flavor that pairs beautifully with the spice blend.
Meal-Prep Friendly: Make a full batch and portion it into containers with rice for easy lunches throughout the week. Reheat gently on the stove or in short microwave bursts, stirring frequently, to keep the shrimp from turning tough.
Frequently Asked Questions
Can I make this ahead of time? The blackening seasoning can be made well in advance and stored in an airtight container for weeks, which makes prepping this dish even faster on the day you cook it. The shrimp itself is best seared fresh, since blackened dishes rely on that immediate, high-heat char for the best texture and flavor.
What can I use instead of a cast iron skillet? Any heavy-bottomed, oven-safe skillet that holds and distributes heat well will work, including stainless steel. Just make sure it’s fully preheated before adding the shrimp, since the intense heat is essential to getting that classic blackened char.
Is blackened shrimp very spicy? It has a noticeable kick from the cayenne pepper, but the garlic herb butter at the end helps mellow the heat significantly. You can easily adjust the spice level up or down by increasing or decreasing the cayenne in the seasoning blend.
Can I use frozen shrimp? Yes — just make sure it’s fully thawed and patted very dry before seasoning, since excess moisture will prevent the spice coating from charring properly. Thaw it overnight in the fridge or under cold running water if you’re short on time.
What should I serve with blackened shrimp? Rice, grits, or crusty bread are all classic pairings that soak up the garlic herb butter beautifully, while a simple green salad or steamed vegetables add a fresh, light contrast. It’s also delicious tucked into tacos or served over a bed of greens for a lighter meal.
