Sheet Pan Salmon with Asparagus

The vibrant rich lemon butter sauce really enhances the flavor of the salmon and the asparagus. Pair with a light salad and ring that dinner bell. Or call this sheet pan salmon a meal in one.

What Do I Need For This Recipe

Salmon – I used a large slice of salmon, but you are welcome to use individual filets if you would prefer.

Asparagus – We love asparagus with salmon. But you can use other veggies like broccoli, carrots, etc.

Butter – I recommend real butter not margarine as it will affect the flavor of the dish.

Lemons – Lemon juice and sliced lemons are great for this salmon recipe.

Spices – Salt, pepper, onion powder, parsley, and minced garlic.

Skin on Or Off For This Sheet Pan Salmon Recipe?

I find leaving the skin on salmon is a great way to keep your fish together. Otherwise, you might find the salmon falls apart as it is baked in the oven.

So for personal preference we always keep the skin on and then you can remove from the skin before serving, or each person can discard after they eat the fish.

How to Make the Butter

Take softened butter, lemon juice, salt, pepper, onion powder, and parsley and mix well. This is going to be the base to your fish, and it is such a delicious blend.

How Long To Cook Salmon In The Oven

I baked my salmon at 450 degrees for around 15 minutes, then turned it over to broil at the end. You will find that depending on the size and thickness of your salmon the cook time will vary.

How to Know When Salmon Is Cooked

One way to tell when your salmon is done is taking a fork and pressing into the fish. If it flakes easy it is done. But for me I always like to use a meat thermometer to ensure it is fully cook.

Salmon needs to read 125 to 130 degrees for a medium cooked salmon. If you want it more well done then go right ahead and cook it a bit longer.
