Ingredient Notes
The Cajun seasoning is where all the flavor comes from, and it’s a simple mix of paprika, cayenne, garlic powder, onion powder, dried thyme, and dried oregano. Smoked paprika in particular gives the seasoning a deeper, more authentic flavor than sweet paprika alone, so it’s worth using if you have it, though either works.
Good-quality butter is essential here since it’s such a central flavor in the finishing sauce, and using a generous amount is part of what balances out the heat from the Cajun seasoning. Fresh garlic, rather than the jarred or powdered kind, also makes a real difference in how vibrant the final sauce tastes.
For the shrimp itself, medium to large peeled and deveined shrimp sear quickly and evenly, which is ideal for this fast, pan-based method. Make sure to pat the shrimp completely dry before seasoning — any leftover moisture will prevent the Cajun coating from sticking and searing properly.
🔥 Cajun Garlic Butter Shrimp Recipe
Prep Time: 5 minutes | Cook Time: 10 minutes | Total Time: about 15 minutes Servings: 4
Ingredients
For the Cajun Seasoning:
- 1 1/2 tsp smoked paprika
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- 1/2 tsp cayenne pepper (adjust to taste)
- 1/2 tsp dried thyme
- 1/4 tsp dried oregano
- 1/2 tsp salt
- 1/4 tsp black pepper
For the Shrimp:
- 1.5 lbs large shrimp, peeled and deveined
- 1 tbsp olive oil
For the Garlic Butter Sauce:
- 5 tbsp unsalted butter, divided
- 6 cloves garlic, minced
- 1/4 cup chicken broth
- 2 tbsp fresh lemon juice
- Pinch of red pepper flakes (optional, for extra heat)
For Finishing:
- 2 tbsp chopped fresh parsley
- Lemon wedges, for serving
For Serving:
- Cooked rice, pasta, or crusty bread
Instructions
Step 1: Mix the Cajun seasoning. In a small bowl, combine the smoked paprika, garlic powder, onion powder, cayenne, thyme, oregano, salt, and pepper, stirring well to distribute everything evenly.
Step 2: Season the shrimp. Pat the shrimp completely dry with paper towels, then toss with the olive oil in a large bowl. Sprinkle the Cajun seasoning over the shrimp and toss again until every piece is evenly coated. Tip: pat the shrimp very dry before adding the oil and seasoning — any leftover moisture will prevent the spice coating from sticking and searing properly.
Step 3: Sear the shrimp. Heat a large skillet over medium-high heat until hot. Add the seasoned shrimp in a single layer and cook for about 1–2 minutes per side, until deeply golden with slightly charred edges and just cooked through. Tip: work in batches if your skillet is small — overcrowding drops the pan’s temperature and prevents that deep, seared color from developing properly.
Step 4: Remove the shrimp. Transfer the seared shrimp to a plate and set aside. The Cajun seasoning should have created a nicely browned, slightly crusty exterior on each piece.
Step 5: Build the garlic butter base. Reduce the heat to medium and add 3 tablespoons of the butter to the same skillet, scraping up any flavorful browned bits left behind from the shrimp. Once melted, add the minced garlic and red pepper flakes (if using), cooking for about 30–60 seconds, stirring constantly, until fragrant.
Step 6: Deglaze the pan. Pour in the chicken broth, continuing to scrape up any remaining browned bits, and let it simmer for 1 minute to reduce slightly and concentrate the flavor.
Step 7: Add the lemon and finish with butter. Stir in the lemon juice, then remove the skillet from the heat and swirl in the remaining 2 tablespoons of butter until melted and glossy. This final addition of butter off the heat gives the sauce a rich, silky finish.
Step 8: Return the shrimp and serve. Add the seared shrimp back into the skillet, tossing gently to coat in the garlic butter sauce, and warm through for about 1 minute. Serve immediately over rice, pasta, or with crusty bread, garnished with fresh parsley and lemon wedges.
Recipe Notes
- Make sure your kitchen has good ventilation — searing Cajun-seasoned shrimp over higher heat can produce a bit of smoke, so turn on your exhaust fan if needed.
- Avoid boiling the sauce vigorously once the final butter is added, since high heat can cause it to separate instead of staying smooth and glossy.
- Leftover Cajun seasoning keeps well in an airtight container for months and works great on chicken, fish, or steak too.

Storage & Reheating
Leftovers will keep in an airtight container in the fridge for up to 2 days. Reheat gently on the stovetop over low heat, stirring occasionally, being careful not to overheat, since shrimp can quickly turn tough when reheated too aggressively.
This dish isn’t a great candidate for freezing, since the butter-based sauce can separate once thawed and the shrimp’s texture suffers. If you’d like to prep ahead, the Cajun seasoning blend can be mixed well in advance and stored in an airtight container until you’re ready to use it.
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 Cajun seasoning blend from spices you likely already have rather than buying a premade mix.
Variations
Healthier/Lighter Version: Reduce the butter to 3 tablespoons total and add an extra splash of chicken broth to lighten the sauce while still keeping plenty of bold Cajun flavor. This version is already fairly light as written, so this swap mostly trims extra fat.
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 pasta. Just double-check that your Cajun seasoning blend doesn’t contain any added sugar.
Extra Spicy Version: Increase the cayenne pepper, or add a pinch of ground chipotle powder along with the Cajun seasoning for even more heat and a subtle smokiness. This pairs especially well with the richness of the butter.
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? You can mix the Cajun seasoning well in advance and store it in an airtight container, but it’s best to sear the shrimp fresh right before serving for the best texture and char. This makes the actual cooking step quick whenever you’re ready to eat.
Is this dish very spicy? It has a noticeable kick from the cayenne in the Cajun seasoning, but the garlic butter sauce helps mellow the heat significantly. You can easily reduce the cayenne if you’d like a milder version, or increase it for extra spice.
Can I use a store-bought Cajun seasoning blend instead? Yes — a good-quality store-bought Cajun seasoning works well as a shortcut, though blends vary quite a bit in saltiness and heat level, so taste and adjust as you go. If your blend already contains salt, you may want to reduce or skip the added salt in the recipe.
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 sticking and searing properly. Thaw it overnight in the fridge or under cold running water if you’re short on time.
What should I serve with Cajun garlic butter shrimp? Rice, pasta, or crusty bread are all great for soaking up the sauce, while a simple green salad or steamed vegetables add a fresh, light contrast. This dish is also delicious tossed into tacos or served over grits for a Southern-style twist.
