Choosing the Best Salmon

For the best results, I like to buy salmon cut from the thicker end of the fillet and ask the fish counter to leave the skin on.

Choose fillets of similar thickness for even cooking.

The skin helps protect the fish while it cooks, keeping it moist and tender. Once the salmon is cooked, the skin separates easily from the fish and can be removed before serving if you prefer.

Fresh or frozen salmon both work well in this recipe. If using frozen salmon, thaw it completely and pat it dry before seasoning.

The Secret Is the Southwest Seasoning

The bold flavor in this southwestern salmon recipe comes from a simple homemade Southwest seasoning blend. I usually make my own because it's easy, inexpensive, and I always have the ingredients on hand.

The combination of smoky spices pairs beautifully with salmon and creates a flavorful crust as it roasts.

If you haven't made homemade Southwest seasoning before, it's worth keeping a batch in your pantry. You'll find plenty of ways to use it beyond this recipe.

Why Sriracha Mayo Works So Well with Salmon

The creamy sriracha lime sauce is what takes this recipe from good to memorable.

The richness of the mayonnaise balances the heat of the sriracha, while fresh lime juice brightens the entire dish. Together they create a sauce that's creamy, slightly spicy, and perfect with salmon.

You can easily customize the heat level by adding more or less sriracha.

What to Serve with Southwest Salmon

This spicy baked salmon pairs well with simple side dishes.

Some of my favorites include:

A cool ranch or blue cheese dressing alongside a salad provides a nice contrast to the spicy salmon.

How to  Make Southwest Salmon with Sriracha Lime Sauce

Ingredients

  • One 6 to 8-ounce salmon fillet per person

  • 1 to 2 tablespoons olive oil

  • Southwest seasoning, to taste

  • 1/4 cup mayonnaise

  • 1 to 2 teaspoons sriracha sauce, or more to taste

  • 1 to 2 teaspoons fresh lime juice

Directions

Preheat the oven to 425°F. Line a baking sheet with aluminum foil for easy cleanup.

Pat the salmon dry with paper towels. Place the salmon skin-side down on the prepared baking sheet. Brush the tops lightly with olive oil, or use this handy oil sprayer.

Sprinkle the salmon generously with Southwest seasoning.

Bake for 10 to 12 minutes, depending on the thickness of the salmon and how well done you prefer it. The salmon is done when it flakes easily with a fork.

While the salmon cooks, prepare the sauce.

In a small bowl, stir together the mayonnaise, sriracha, and lime juice. Taste and adjust the sriracha until the sauce reaches your preferred level of heat.

Serve the salmon with a drizzle of the sriracha lime sauce and additional sauce on the side.

My Tips for Success

  • Leave the skin on during cooking to help keep the salmon moist.  A  handy fish spatula will help you remove the skin easily if you prefer.

  • Use foil for quick cleanup.

  • Don't overcook the salmon. It should flake easily but still remain moist inside.

  • This recipe works beautifully on the grill. Simply place the salmon on a piece of foil and grill until cooked through.

  • Leftover salmon is delicious served cold over a salad the next day.
