This Garlic Parmesan Baked Keto Salmon Recipe is the easiest ways to make a healthy and delicious low carb salmon dish! It is a fool proof keto salmon recipe that’s best made with frozen salmon and has only 1g net carbs per serving! Tender & perfectly cooked salmon topped with a delicious blend of parmesan, garlic and parsley held together with full fat mayonnaise.
This recipe is not only perfect for a keto diet meal, but it’s also gluten-free and grain-free! This keto salmon recipe is also delicious as leftovers the next day, eaten reheated or even room temperature!
I originally published this recipe in 2016, ever since it’s been on of the most popular recipes here at HSITK and I figured it was time to give it a little 2023 update. Fresh new photos AND I’ve found that it’s not necessary to cook the topping or this easy keto salmon, if you are using room temperature softened butter.
Enjoying salmon filets at least once a week is my favorite way to make sure that I’m incorporating ample healthy fats into my diet. This baked salmon recipe as well as my Asian Salmon are weekly meal plan staples as is wild-caught salmon on my grocery list. They are both equally delicious recipes that are packed with so much flavor, and a great way to enjoy tender salmon as a part of your low carb diet.

What is the Best Salmon?
I can’t stress enough the importance of choosing Wild Caught Salmon for it’s health benefits and overall heart health. Wild caught salmon has a healthier ratio of anti-inflammatory omega-3 fats to inflammatory omega-6 fats, as well as an overall better nutritional profile. Farmed salmon is not sustainable and may harm the environment by spreading disease to wild-caught fish and encouraging overfishing as well as contributing to heart disease and inflammation.
For this low carb salmon recipe, you can use any type of wild salmon that you prefer; Coho Salmon, Sockeye Salmon, King Salmon, Atlantic Salmon etc.. If you don’t know the difference in the types of salmon, read THIS Guide to Every Type of Salmon you can Buy.
We live in a small rural town and finding high quality seafood like wild caught salmon can be challenging. So, I love that I can rely on Thrive Market not only for pantry staples but they also offer wild caught fish, too
Can you cook Frozen Salmon?
One of the best attributes of this recipe is that there is no need to thaw your salmon before cooking! It not only makes it the easiest way to cook salmon but it also is what makes it a fool proof way to make perfect salmon every time!
By baking frozen salmon, you get a little extra time for the garlic parmesan topping to get nicely golden brown without over cooking your salmon on the inside.
My other favorite frozen salmon recipes are my 5 Minute Pressure Cooker Salmon and Rice Pilaf and my Oven Baked Salmon Asparagus & Spaghetti Squash with Lemon Beurre Blanc!
Of course, if you’re lucky enough to have fresh salmon available to you, it will work just as well in this low carb salmon recipe, it will just take less time to bake!

I’m always asked about substitutions, so feel free to use other herbs if desired, dill would also be wonderful in this easy keto salmon recipe. You can also add a squeeze of fresh lime or lemon juice, a dollop of dijon mustard, splash of soy sauce or coconut aminos. I’ve had readers say that they used cilantro and it was delicious too.
Simply combine butter, mayonnaise, parmesan cheese, garlic and parsley. I like to use my mini food processor, however a small bowl and spoon will work good too.
If your butter is not room temperature/soft, feel free to use melted butter from the stove or microwave.
Give your salmon a lightly season the skin salt and pepper and place it skin side down on a a baking sheet lined with unbleached parchment paper. (foil works too)
Then top it with the garlic parmesan mixture. And don’t be afraid to spread it on thick!
This recipe will work perfectly with either one large filet (fillet) or several individual pieces, whichever works best for you! I typically let my ideal serving size (in ounces or gram of protein you’re aim for) guide the portions that I make for dinner.
Bake your garlic parmesan topped salmon at 350 degrees F. Frozen salmon will take 20-25 minutes depending on how thick your filet(s) are, thawed salmon will be done in roughly 15 minutes.
