Step‑by‑Step Instructions for Cajun Shrimp and Salmon with Garlic Cream Sauce, Mashed Potatoes, and Green Beans
Step 1: Prepare the Proteins
Start by seasoning the shrimp and salmon with your Cajun spices to enhance the flavor. Heat a large skillet over medium-high heat, adding a splash of olive oil. Cook the shrimp for about 2-3 minutes on each side, or until they turn pink and opaque. For the salmon, cook for about 4-5 minutes on each side until it flakes easily with a fork, achieving that perfect texture.
Step 2: Make the Garlic Cream Sauce
In the same skillet, lower the heat to medium and add minced garlic, sautéing until fragrant, about 1 minute. Pour in heavy cream (or coconut milk for a dairy-free option) and let it simmer gently for 2-3 minutes. Stir in Parmesan cheese and additional Cajun spices, allowing the sauce to thicken while you continuously mix, creating a creamy, rich garlic cream sauce that perfectly complements the seafood.
Step 3: Whip Up the Mashed Potatoes
While the sauce is simmering, bring a pot of salted water to boil. Add peeled and chopped potatoes, cooking for about 15-20 minutes until they are tender. Drain the potatoes, then return them to the pot. Mash them with butter and warm cream until smooth, seasoning with salt and pepper to taste. This comforting side will pair beautifully with your Cajun shrimp and salmon.
Step 4: Blanch the Green Beans
In a separate pot, bring water to a boil and add the trimmed green beans. Blanch them for about 3-4 minutes until they are bright green and tender-crisp. Immediately transfer the beans to an ice bath to stop the cooking process, ensuring they maintain their vibrant color and crunch, perfectly contrasting the richness of the Cajun shrimp and salmon dish.
Step 5: Assemble and Serve
Finally, it’s time to plate your masterpiece! Spoon the creamy garlic sauce over the Cajun shrimp and salmon, allowing it to cascade down onto the plate. Arrange the buttery mashed potatoes and green beans beside the seafood, creating a colorful presentation. Serve your delicious Cajun Shrimp and Salmon with Garlic Cream Sauce, Mashed Potatoes, and Green Beans hot, inviting your family to enjoy a delightful meal together.

Cajun Shrimp and Salmon with Garlic Cream Sauce Recipe FAQs
What is the best way to select ripe shrimp and salmon?
Absolutely! When choosing shrimp, look for those that are firm, shiny, and have a mild ocean smell. Avoid shrimp with dark spots or a strong odor. For fresh salmon, select fillets that are bright in color and have a moist, slightly firm texture. If you’re using frozen, ensure they are stored at 0°F for quality and freshness.
How should I store leftovers from this dish?
Store any leftover Cajun Shrimp and Salmon with Garlic Cream Sauce in an airtight container in the refrigerator. They can last up to 2 days. Make sure to reheat gently to prevent overcooking the seafood. If you’ve already mixed them with the sauce, keep in mind this will slightly shorten their shelf life.
Can I freeze the Cajun Shrimp and Salmon dish?
Yes, you can! To freeze, separate the shrimp and salmon from the garlic cream sauce. Place the seafood in a freezer-safe bag or container, and it can last up to 3 months. When ready to use, thaw overnight in the refrigerator. For the garlic sauce, it’s best prepared fresh, but you can freeze a version using just heavy cream for later use.
What troubleshooting tips do you have for the garlic cream sauce?
Very! If your garlic cream sauce turns out too thick, simply whisk in a little more cream or broth over low heat until you reach the desired consistency. If it’s too thin, let it simmer a bit longer, allowing it to reduce. Also, be cautious not to burn the garlic; sauté it just until fragrant to avoid bitterness.
What dietary considerations should I keep in mind?
If you’re cooking for someone with allergies, check that the shrimp and salmon are sourced from a place free of cross-contamination with shellfish if there are shellfish allergies. For a dairy-free option, use coconut milk instead of heavy cream and ensure any cheese used is dairy-free.
Can I substitute the proteins in this recipe?
Absolutely! This recipe is incredibly versatile. You can substitute shrimp with scallops or lobster for a richer seafood experience, or opt for chicken breast for a lighter, non-seafood alternative. Just adjust the cooking times accordingly, ensuring everything is cooked perfectly!
