Ingredients

4 salmon fillets, about 6 ounces each
1 pound asparagus, trimmed
2 tablespoons olive oil, divided
3 tablespoons unsalted butter
4 garlic cloves, minced
1 lemon, thinly sliced, plus 2 tablespoons fresh lemon juice
1/2 teaspoon paprika
1/2 teaspoon Italian seasoning
Salt and black pepper, to taste
2 tablespoons chopped fresh parsley, for serving

How to Make Lemon Garlic Butter Salmon and Asparagus

First, pat the salmon dry. Season both sides with paprika, Italian seasoning, salt, and black pepper.
Next, heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the asparagus and cook for 4 to 5 minutes, turning occasionally, until bright green and just tender. Transfer it to a plate.
Then, add the remaining olive oil to the skillet. Place the salmon skin-side down, if applicable, and sear for 4 minutes.
Carefully flip the salmon and cook for another 3 to 4 minutes, or until it flakes easily and reaches 145°F internally. Transfer the salmon to the plate with the asparagus.
After that, reduce the heat to medium. Melt the butter in the same skillet, then add the garlic and cook for about 30 seconds, until fragrant.
Stir in the lemon juice and arrange the lemon slices in the pan. Return the salmon and asparagus to the skillet, spoon the sauce over everything, and warm for 1 to 2 minutes.
Finally, garnish with fresh parsley and serve immediately.

Pro Tips for the Best Lemon Garlic Butter Salmon Skillet

Pat the salmon dry before seasoning so it sears instead of steaming.
Use salmon fillets with a similar thickness so they finish cooking at the same time.
Do not overcrowd the skillet; cook in batches if necessary.
For thicker asparagus, blanch it briefly first or allow a few extra minutes of cooking time.
Use an instant-read thermometer and remove the salmon when it reaches 145°F in the thickest part.
For a richer sauce, add a splash of chicken broth or white wine with the lemon juice.

Storage Instructions

Allow leftovers to cool, then place them in an airtight container and refrigerate within 2 hours. They will keep for up to 3 days. Reheat gently in a covered skillet over low heat or in the microwave at 50% power, because high heat can dry out the salmon. Store the asparagus and salmon together or separately, depending on how you plan to serve them.

Lemon Garlic Butter Salmon and Asparagus FAQ

Can I use frozen salmon?

Yes, but thaw the salmon completely in the refrigerator first. Then, pat it very dry before seasoning so the fillets brown properly.

Can I replace the asparagus?

Absolutely. Green beans, broccoli florets, zucchini, or snap peas are excellent alternatives. However, adjust the cooking time based on the vegetable you choose.

How do I know when the salmon is done?

The salmon should flake easily with a fork and reach 145°F in the thickest section. Additionally, the center should look opaque rather than translucent.

Can I make this recipe dairy-free?

Yes. Replace the butter with a dairy-free butter alternative or use additional olive oil. The lemon and garlic will still create a flavorful sauce.
