Garlic Butter Salmon and Asparagus

This keto salmon recipe is coated in garlic butter and baked with salmon all on one sheet pan for easy prep and clean up! The salmon is perfectly juicy and flaky and the asparagus turns out tender-crisp with the most amazing flavor thanks to all the garlic butter.

I’ll be the first to admit that I’m not a huge fish lover, but I’m trying hard to change my ways.

Fish can be such a healthy protein and it’s a nice change of pace when we’re getting tired of eating the same old chicken or beef. Especially when it’s topped with garlic butter!

This reminds me a bit of our garlic butter pork tenderloin – a reader favorite and so darn good! This is even easier though since it cooks right alongside the asparagus and your whole dinner is done on one pan!

I think you’re going to love this one!

Keto Salmon Recipe Ingredients:

Salmon – There are a few different types of salmon such as Atlantic, King, Sockeye, or Coho. They are similar but have somewhat different flavors and fat content. Atlantic salmon tend to be farm raised while the other varieties are often wild caught, which are considered healthier but also more expensive. Use whatever type you want for this garlic butter salmon and asparagus recipe!

Asparagus – Fresh, trimmed asparagus is the perfect complement to this salmon. They both have powerful flavors that go well with each other and are even better with all that garlic butter flavor to balance them out!

Garlic Butter – Lots of melted butter with plenty of minced garlic, parsley, and onion powder make for an easy but incredibly flavorful butter sauce to drizzle over the salmon filets and asparagus. They’ll bake up perfectly in all that garlic butter and take on even more flavor.

Lemon – The fresh slices of lemon will get placed over the salmon filets before baking and add a fresh pop of citrus.

Why We Love This Recipe:
  • Fish is not something that we have very often but it is great to change things up now and then and try something different without being fussy or difficult.
  • All that garlic butter! What’s not to love about that?
  • Seafood, when eaten in moderation, can be very good for you, and salmon in particular is packed full of healthy omega-3 fatty acids and vitamins.

How To Bake Salmon In The Oven:

  • Arrange – To start, you’ll want to spray a baking sheet with non-stick spray. Lay out your salmon fillets in the center of the baking dish with a bit of space between each piece of salmon. Surround the edges with trimmed asparagus.
  • Garlic Butter – Time to whip up some garlic butter – this is just melted butter, garlic, parsley, and onion powder. Super easy and super flavorful! Whisk all that together and then drizzle the garlic butter over all of the salmon and asparagus.

  • Lemon – The final step before baking is to top each of the garlic butter salmon fillets with a slice of lemon! The lemony citrus flavor works very well with the salmon and the garlic butter. It will definitely add to the flavor so don’t skip the lemon.

  • Bake – We’re baking this garlic butter salmon and asparagus recipe at 450 degrees Fahrenheit. That’s a pretty hot oven, which means that it’ll go nice and quick! Bake the salmon for 12-15 minutes. Wondering how to tell if your salmon is done? It should look opaque all the way through and flake easily with a fork. It’s totally fine to eat salmon a little under done, so if you think it looks done, pull it out of the oven! Better to have slightly under done salmon than over done, dry and tough salmon.

How long to bake salmon?

It doesn’t take very long at all for this keto salmon recipe to bake since we’re using such a hot oven. Set your oven to 450 degrees Fahrenheit and bake for 12-15 minutes or until it is opaque and flaky throughout.

Is baked salmon good for you?

Salmon is an excellent source of high quality protein, it’s high in B-vitamins, and it’s a good source of potassium. It’s also full of omega-3 fatty acids which is what makes it so good for your brain! This is a low carb salmon recipe paired with healthy asparagus and topped off with a good fat – butter. All around, this baked salmon recipe is a great choice for your low carb diet!

How to reheat salmon?

If you’ve got leftover salmon, you’ll want to be sure you reheat it properly so that it doesn’t dry out. You’ll want to go low and slow, heat it at 275 degrees Fahrenheit for about 15 minutes. You’ll also want to add a little water or perhaps more garlic butter sauce to also help keep it from drying out. It will also help to cover it loosely with foil to keep the edges from getting too crisp.

      Hi Carol! So glad you enjoyed the recipe! The star rating is up in the recipe card – not super useful, right? We’re working on a new site design and will hopefully have that in an easier to find spot! 🙂

  3. What a quick, easy and delicious recipe! Took me about 5 minutes to put it together and 12 minutes in the oven, and I had all the ingredients on hand. Thank you for posting!

  4. Can you use frozen asparagus for this recipe at all? I have tons of frozen that needs to be used.

    1. Karly Campbell

      Hi Veronica! I’ve actually never worked with frozen asparagus, so I’m not sure how it holds up to roasting.

  5. Stephanie R LeBlanc

    Since hubby and I DON’T like salmon at all, can another type of fish be used, like cod or halibut?
