What do you need to make salmon stuffed mushrooms?

  • Baby bella mushrooms – Organic mushrooms are best.
  • Salmon – Bake or roast the salmon ahead of time and shred it up.
  • Cauliflower rice – This low carb alternative to white or brown rice is surprisingly easy to make at home but you can always buy frozen cauliflower rice instead.
  • Red bell pepper – Chopped bell peppers add a slight sweetness and crunch to each bite.
  • Herbs and seasonings – Just the simple stuff, like fresh parsley, old bay seasoning, salt, and pepper.

How to make salmon stuffed mushrooms

These easy stuffed mushrooms with salmon are totally foolproof and take very little time to prepare. They’re Awaken180° Weightloss approved, so you and all of your friends can enjoy the flavorful bites guilt-free!

Step 1: Rinse the mushrooms in cold water and towel dry them. Remove the stalks (save them for mushroom soup!) while keeping the gills in place. Transfer the hollowed mushrooms to a bowl.

Step 2:
Toss the mushrooms in olive oil, salt, and black pepper. Let them marinate while you work on the salmon stuffing.

Step 3: Add the shredded salmon, cauliflower rice, and chopped bell pepper to a skillet over medium heat. Add the old bay seasoning, salt, pepper, and fresh parsley and cook until heated through.

Step 4: Place the mushrooms open side up on a baking dish and add a scoop of the salmon stuffing into each one.

Step 5: Bake the stuffed mushrooms until the mushrooms are soft. It’s ok if there’s some liquid on the bottom of the dish! Transfer them to a serving platter, garnish with fresh parsley and lemon, and enjoy!

Tips to make the best stuffed mushrooms

  • To wash the mushrooms, rinse them gently under cold water and dry them with a clean towel or set them out to air dry. Don’t soak them in water or else they’ll become soggy.
  • It’s completely normal for there to be liquid on the bottom of the baking sheet after the mushrooms are done cooking. Just transfer them to a serving platter so they don’t have to sit in the liquid.
  • You’ll know they’re done cooking when the mushrooms are soft and the filling is super fragrant.
  • Want to make bigger portions? Stuff the salmon filling into portobello mushroom caps and bake them a little longer.

Serving suggestions

These keto and gluten free stuffed mushrooms would be perfect to pass around at any dinner party, potluck, holiday celebration, or get-together! Enjoy a few before dinner or plate them on the side of this Herb Roasted Chicken, Churrasco Steak and Veggies, or a Tuscan Salmon Skillet when you’re in the mood to double up on the salmon.

Can you make them ahead of time?

You can prep the mushrooms and mix the filling together up to 1 day ahead of time. Store them in separate containers in the fridge.

Heat up the filling and assemble the stuffed mushrooms no more than an hour or two before serving. The longer the baked stuffed mushrooms sit, the soggier they’ll become.

How do you store leftovers?

Store the leftover stuffed mushrooms in an airtight container in the fridge for up to 3 days. Either reheat them for a few minutes in the microwave or in a 350ºF oven until warmed through.
