Ingredients You Need

Shrimp
- 1 ½ pounds large shrimp, peeled and deveined, tails on or off
- Use 21/25 or 26/30 count for juicy bites that do not overcook.
- Frozen shrimp work great; thaw them in cold water and pat very dry.
Seasoning and flavor
- 2 ½ to 3 teaspoons Cajun seasoning
- Use a low sodium brand if you watch salt.
- If you use a spicy brand, start with 2 teaspoons and taste before adding more.
- ½ teaspoon smoked paprika, optional, for extra smoky flavor
- ¼ teaspoon cayenne pepper, optional, for more heat
- ½ teaspoon kosher salt, more to taste
- ¼ teaspoon black pepper
Garlic butter sauce
- 4 tablespoons unsalted butter
- Salted butter works; just reduce added salt a bit.
- 1 to 2 tablespoons olive oil
- 5 to 6 cloves garlic, finely minced
- Juice of ½ to 1 lemon, to taste
- Zest of ½ lemon, optional but brightens the sauce
- 2 to 3 tablespoons low sodium chicken broth or seafood stock
- Water works in a pinch; just season a bit more.
Fresh finish
Pantry shortcuts and swaps
- Use pre-minced garlic from a jar when you feel tired; just add a little extra for stronger flavor.
- Use homemade Cajun seasoning if you avoid added sugar; mix paprika, garlic powder, onion powder, oregano, thyme, cayenne, salt, and pepper.
- Use ghee instead of butter if you want a richer, nutty flavor and better high heat cooking.
Equipment
- Large heavy skillet, cast iron or stainless steel
- Tongs or a spatula
- Small bowl for seasoning the shrimp
- Microplane or small grater for lemon zest
- Cutting board and sharp knife
Tips
- Pat the shrimp very dry so the seasoning sticks and the shrimp sear instead of steam.
- Season the shrimp in a bowl before they hit the pan so every piece tastes bold.
- Use medium high heat so the shrimp cook fast and stay juicy.
- Do not crowd the skillet; cook in two batches if needed for better browning.
- Pull the shrimp as soon as they curl and turn opaque; overcooked shrimp turn rubbery fast.
- Add garlic after you cook the shrimp or lower the heat so the garlic does not burn.
- Swirl the butter and broth together until the sauce looks glossy, not greasy.
- Taste the sauce at the end and adjust salt, lemon, and spice so it matches your preference.
How to Make Cajun Shrimp with Garlic Butter Sauce

1: Season the shrimp
Place the peeled and deveined shrimp in a large bowl and pat them dry with paper towels. Sprinkle Cajun seasoning, smoked paprika, cayenne, salt, and black pepper over the shrimp. Toss until every shrimp looks evenly coated, then set the bowl aside while you heat the pan.
2: Sear the shrimp
Heat 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over medium high heat. When the butter foams and the oil shimmers, add shrimp in a single layer without crowding. Cook 1 to 2 minutes per side until the shrimp turn opaque and lightly browned on the edges, then transfer them to a plate.
If you have more shrimp than pan space, cook them in two batches. Add a small splash of oil between batches if the pan looks dry.
3: Build the garlic butter sauce
Lower the heat to medium and add the remaining butter and a drizzle of oil to the same skillet. Add minced garlic and cook about 30 to 60 seconds, stirring, until it smells fragrant and just starts to turn lightly golden. Pour in chicken broth and scrape up any browned bits from the bottom of the pan with a wooden spoon.
Let the sauce simmer for 1 to 2 minutes so it thickens slightly. Stir in lemon juice and zest, then taste and adjust salt and spice.

4: Coat the shrimp and finish
Return the cooked shrimp and any juices from the plate to the skillet. Toss the shrimp in the garlic butter sauce until they look glossy and fully coated, about 1 to 2 minutes. Sprinkle chopped parsley over the top and give everything a final stir.
Turn off the heat and squeeze a little extra lemon over the shrimp if you like a brighter finish. Serve the Cajun Shrimp with Garlic Butter Sauce hot while the sauce still clings to the shrimp.
Different Ways to Try It
- Gluten free: Serve over rice, mashed potatoes, polenta, or gluten free pasta, and use gluten free stock.
- Low carb: Spoon the shrimp over cauliflower rice, zucchini noodles, or sautéed green beans.
- Dairy free: Swap the butter for olive oil or a dairy free butter stick and keep the same method.
- Extra veggies: Add bell peppers, zucchini, or cherry tomatoes to the skillet right after you cook the shrimp, then sauté and finish with the sauce.
- Creamy version: Stir in a splash of heavy cream or coconut milk at the end for a richer Cajun shrimp sauce.
- Extra smoky: Add more smoked paprika or a pinch of chipotle powder with the Cajun seasoning.
How to Serve Cajun Shrimp with Garlic Butter Sauce
Serve Cajun Shrimp with Garlic Butter Sauce over fluffy white rice, brown rice, or buttery mashed potatoes so they soak up the sauce. Crusty bread or garlic bread works great for scooping up every last bit from the skillet. You can pair it with a simple green salad, steamed broccoli, or roasted asparagus for balance. For a fun twist, tuck the shrimp into warm tortillas with a little slaw and turn it into quick Cajun shrimp tacos.
Make-Ahead and Storage Success
Cook the Cajun Shrimp with Garlic Butter Sauce fresh when possible, since shrimp taste best right off the stove. If you have leftovers, cool them completely, then store them in an airtight container in the fridge for up to 3 days. Reheat gently in a skillet over low heat with a splash of broth or water so the shrimp warm through without turning tough. You can freeze cooked shrimp in sauce for up to 2 months, but thaw them overnight in the fridge and reheat very gently for the best texture.

Instructions
- Pat the shrimp dry with paper towels. In a bowl, toss the shrimp with Cajun seasoning, paprika, salt, and black pepper until evenly coated.
