From Start to Finish: Cajun Salmon with Creamy Parmesan Sauce

Step 1: Prepare the Salmon
Start by patting your salmon fillets dry with paper towels. This helps them sear nicely. Season both sides generously with Cajun seasoning and smoked paprika.
Step 2: Sear the Salmon
In a large skillet, heat the olive oil over medium-high heat. Once hot, add the salmon, skin side down if applicable. Sear for about 4-5 minutes on each side until golden brown and cooked through. Remove the salmon from the skillet and set aside on a plate.
Step 3: Create the Sauce Base
In the same skillet, melt the butter. Add the finely diced onion and red bell pepper. Sauté for about 3-4 minutes, or until the vegetables are soft. Add the minced garlic and cook for another minute until fragrant.
Step 4: Make the Creamy Sauce
Pour in the chicken broth, scraping up any browned bits from the bottom of the skillet. Allow it to simmer for a couple of minutes before adding in the heavy cream, crushed red pepper flakes, black pepper, and additional Cajun seasoning. Stir well to combine.
Step 5: Thicken the Sauce
If you prefer a thicker sauce, mix the cornstarch with a little water to create a slurry and add it to the sauce while stirring continuously. Bring it to a gentle simmer until it thickens.
Step 6: Add the Cheese and Finish
Remove the skillet from heat and stir in the freshly grated Parmesan cheese and lemon juice until melted and combined.
Step 7: Combine and Serve
Return the salmon to the skillet, spooning the creamy sauce over the top. Let it warm through for a minute, then garnish with sliced green onions and chopped parsley.
Better Choices & Swaps

- Salmon – Swap for other fish like tilapia or chicken for a different protein.
- Cream – Use half-and-half or a plant-based cream alternative for a lighter version.
- Parmesan – Nutritional yeast can provide a cheesy flavor for a vegan twist.
- Chicken broth – Vegetable broth works well for a vegetarian option.
Easy-to-Miss Gotchas
One common mistake is overcooking the salmon, which can lead to a dry texture. Aim for a medium doneness, where the salmon is opaque but still moist in the center. Also, be careful with the seasoning; Cajun spice blends can vary in heat, so adjust according to your taste preference.
Shelf Life & Storage
This Cajun Salmon with Creamy Parmesan Sauce is best enjoyed fresh, but if you have leftovers, store them in an airtight container in the refrigerator for up to 2 days. Reheat gently on the stove over low heat, adding a splash of chicken broth or cream to loosen the sauce if necessary.
