Common Mistakes to Avoid
- Overcooking the shrimp — Shrimp cook quickly and become rubbery if left on the heat too long.
- Cooking the salmon at excessive heat — Very high heat can brown the outside before the center cooks properly.
- Using too much Cajun seasoning — Many Cajun blends contain substantial salt, so adding extra salt too early can make the dish overly salty.
- Skipping the resting time — A brief rest after cooking allows the salmon to settle and retain more moisture.
Required Equipment
- Large non-stick or cast-iron skillet — Provides even heat and enough space for the seafood.
- Fish spatula — Helps turn salmon fillets without breaking them.
- Instant-read thermometer — Makes it easier to monitor seafood doneness accurately.
- Small bowl — Useful for combining the Cajun seasoning and other spices.
- Tongs — Makes turning and removing shrimp quick and easy.
Storage Instructions
Allow leftovers to cool promptly, then place them in an airtight container and refrigerate within about two hours. Store for up to 3 days for the best quality.
For freezing, place cooled salmon and shrimp in freezer-safe airtight containers or bags. Freeze for up to 2 months for best texture. However, shrimp and salmon may become slightly less tender after thawing.
Thaw frozen leftovers overnight in the refrigerator. Reheat gently in a covered skillet over low heat with a splash of water or broth, or microwave in short intervals until warmed through. Avoid prolonged reheating because seafood can dry out quickly.

📝 Ingredients
Seafood
- 4 salmon fillets, about 5 oz (142 g) each, skin removed if desired
- 1 lb (454 g) large shrimp, peeled and deveined
- 1 tbsp olive oil
Cajun Seasoning
- 2 tsp smoked paprika
- 1 tsp garlic powder
- 1 tsp onion powder
- ½ tsp dried oregano
- ½ tsp dried thyme
- ½ tsp cayenne pepper, adjust to taste
- ½ tsp black pepper
- ½ tsp salt, or less depending on the Cajun seasoning used
Garlic Butter Finish
- 2 tbsp unsalted butter

- 1 tbsp fresh lemon juice
- 1 tbsp chopped fresh parsley
- ½ lemon, cut into wedges for serving
Ingredient note: If using a store-bought Cajun seasoning blend, check its salt content before adding the additional salt listed above.
Directions
- Prepare the seafood.
Pat the salmon and shrimp dry with paper towels. Removing excess moisture helps the seafood develop better browning instead of steaming. - Make the Cajun seasoning.
In a small bowl, combine smoked paprika, garlic powder, onion powder, oregano, thyme, cayenne, black pepper, and salt. - Season the salmon and shrimp.
Coat both sides of the salmon with the Cajun mixture. Toss the shrimp with the remaining seasoning until evenly coated.
High-protein tip: Pat the seafood dry before seasoning so the spices adhere well without needing extra flour or breading. - Heat the skillet.
Heat a large skillet over medium-high heat for about 2 minutes. Add olive oil and allow it to become hot but not smoking. - Cook the salmon.
Place the salmon fillets in the skillet and cook for approximately 4–5 minutes on the first side. Flip carefully and cook another 3–4 minutes, depending on thickness.
Visual cue: The salmon should become opaque around the edges while remaining moist in the center. - Check the salmon.
For food safety, use an instant-read thermometer and cook the salmon to the appropriate internal temperature. Avoid overcooking because salmon can quickly become dry. - Cook the shrimp.
Transfer the salmon to a clean plate. Add the shrimp to the same skillet and cook over medium-high heat for approximately 1–2 minutes per side.
Visual cue: Shrimp should turn pink and opaque and curl into a loose “C” shape. - Make the garlic butter.
Reduce the heat to medium-low. Add butter and minced garlic to the skillet and cook for 30–60 seconds, just until fragrant. Avoid browning the garlic heavily. - Add lemon.
Stir in the fresh lemon juice and scrape up any flavorful browned bits from the skillet. - Return the salmon.
Place the salmon back into the skillet and spoon the garlic butter over the fillets and shrimp. Cook for 30–60 seconds to bring everything together. - Finish with herbs.
Sprinkle with fresh parsley and add a squeeze of lemon.
Flavor tip: Fresh lemon balances the richness of the butter and salmon and brightens the Cajun spices. - Serve immediately.
Serve the salmon and shrimp with roasted asparagus, broccoli, zucchini, cauliflower rice, or a fresh green salad.
