Ingredient Notes
The Cajun seasoning is the key flavor driver here, bringing smoky heat and depth to both the shrimp and salmon. Fresh garlic is essential for the sauce—it builds that rich, aromatic base. Heavy cream gives the sauce its smooth, velvety texture, while Dijon mustard adds a subtle tang that balances the richness.
For the mashed potatoes, russet potatoes work best because they mash up soft and fluffy. Butter and milk create that classic creamy consistency. Fresh green beans add a crisp, fresh contrast that keeps the dish from feeling too heavy.
Ingredient Substitutions
- Swap salmon with cod, tilapia, or chicken breast if preferred
- Use half-and-half instead of heavy cream for a lighter sauce
- Replace chicken broth with vegetable broth if needed
- Use turkey bacon or skip entirely if adding a smoky element (no pork)
- Substitute green beans with asparagus or broccoli
- Use dairy-free butter and milk for a dairy-free version
- Adjust Cajun seasoning or use a mild blend for less heat
How to Make It
Step 1: Prepare the Mashed Potatoes
Boil potatoes in salted water for 15–20 minutes until fork-tender. Drain and mash with butter and milk until smooth. Season with salt and pepper and set aside.
Step 2: Cook the Shrimp
Heat olive oil in a skillet over medium-high heat. Season shrimp with Cajun seasoning and cook for 2–3 minutes per side until pink. Remove and set aside.
Step 3: Cook the Salmon
In the same skillet, melt butter. Add salmon and cook 4–5 minutes per side until flaky. Remove and set aside.
Step 4: Make the Garlic Cream Sauce
In the same pan, melt butter and sauté garlic for 1–2 minutes. Add cream, chicken broth, Dijon mustard, salt, pepper, and smoked paprika. Simmer 4–5 minutes until slightly thickened.
Step 5: Combine Seafood
Return shrimp and salmon to the skillet. Spoon sauce over and simmer for 2–3 minutes.
Step 6: Cook the Green Beans
Boil green beans for 3–4 minutes, then drain. In a pan, melt butter and sauté garlic and red pepper flakes. Add green beans and cook 3–4 minutes until slightly caramelized.
Step 7: Assemble and Serve
Plate mashed potatoes, top with salmon and shrimp, and drizzle with garlic cream sauce. Serve green beans on the side.
