Garlic Butter Salmon and Mushrooms – Low-carb, 15-min Recipe

Salmon fillets are a mainstay on on my weekly dinner menu. Whether fresh or from frozen, salmon is a quality protein that makes the perfect blank canvas, ready to be “painted” with colorful vegetables and the seasonings that suit your mood of the moment!

When it comes to seasonings and flavor, garlic can’t be beat. It has a host of functional health benefits, is umami-friendly and maximizes the flavor of everything it’s paired with, from veggies, to proteins, to grains, pastas and bread . . ahh, garlic bread. Distinctively pungent, yet more mellow upon cooking, garlic is probably the “first reach” seasoning in my kitchen. If I could only pick one seasoning (other than salt and pepper) for a dish, it would be garlic — that’s how I keep life easy! Fresh minced or crushed garlic is the best, but when I’m making a quick dinner recipe, I rely on the convenience of minced garlic in a jar, garlic paste in a tube, or pre-portioned frozen crushed garlic.

Minced fresh garlic if you have the time, but purchased garlic in jar, tube or frozen portions is convenient!

I drooled earlier about buttery garlic bread, but buttery garlic MUSHROOMS – ohhhhyeah! Low-cal and low-carb, can be a little bland on their own — but with just a little butter and garlic, any mushroom side dish becomes heaven! You can use white button mushrooms or baby bellas (cremini) mushrooms in this low-carb salmon recipe — both act like little sponges that soak up all the rich flavor.

A quick little 15-second tutorial!

Pro-Tips:

1) Leave bottom skin on salmon, this makes a richer recipe and makes the cooking process easier (less sticking). You can remove it later . . . but remember, the brown/gray “gunk” between the skin and salmon flesh is salmon fat and where most of the beneficial Omega-3 fatty acids reside.

2) Salmon is cooked in 2 steps. First a sear with the skin side up. Then the par-cooked salmon rests on a plate while the veggies cook. Second, the fish is finished off by cooking skin side down among the vegetables, with a lid on top of the skilled to expedite the process. Make sure to have the lid nearby.

3) You can substitute peeled, de-veined jumpo shrimp. Those will cook for 3 to 4 minutes UNTIL DONE on the first step, and then you add back into the recipe when the vegetables are finished. Don’t add cooking time after this, or they will become rubbery.

4) For this garlic mushroom salmon skillet recipe, a non-stick skillet/fry pan with lid (10″) works well to keep the garlicked up salmon from sticking to the pan on the searing step. However, if you don’t have a non-stick or don’t want to use a non-stick, and end up with some bits burned onto the pan, there is a solution. After removing fish to rest on plate, add a splash of water to the hot skilled to sizzle and then quickly scrape off with spatula.

5) This mushroom salmon recipe scales up easily. To make 4 servings, just double the recipe (fine to be loosy-goosey on vegetables) and use a 12″ non-stick skillet/frypan with lid.

    We love salmon and I usually grill it because I am not a great fish cook. Tried your recipe and it came out delicious. I loved the mushrooms and spinach that made it a great meal.

    I used Atlantic Salmon ( do not like farmed Salmon – health Fanatic } .I used brown Button Mushrooms and plenty of Garlic. In the meantime I steamed Broccoli and Brussel Sprouts . Added Butter to the Salmon and just before the Salmon was cooked added the Veggies to the Salmon . A Meal for the Gods. Will do it again.
    Thanks for the Recipe.
