an easy keto stuffed mushrooms recipe

These keto sausage stuffed mushrooms couldn't be more simple to prepare. A quick sauté, a whip of the fluffy filling, and then it's all baked to perfection in the oven.

Start by washing and cleaning each of the mushrooms, gently scrubbing away any dirt (you can also run them under running water or use a damp paper towel to gently wash them).

I prepare them for stuffing by carefully breaking the stems off so only the mushroom caps remain.

This recipe does not call for the stems to be used- I usually discard them but you could certainly save them for something else (like mushroom soup!).

Once the mushrooms are prepped, follow this simple process (see the recipe card at the bottom of the page for the ingredient amounts and detailed instructions):

1. Cook on the stovetop. Cook the pork sausage in a large skillet with oil, along with the diced onion and celery. You want to brown the sausage and soften the vegetables. Add the minced garlic and fresh sage, and cook for another couple of minutes.
2. Mix up the filling. Place the cream cheese in a mixing bowl. Add the sausage mixture, paprika, salt, and pepper. Mix it until the cream cheese mixture is well combined.
3. Assemble and bake. Spoon about a tablespoon of the filling into each of the clean mushrooms, piling it up so it sits on top of the mushroom. Continue until each of the mushrooms are done and you run out of filling. Place them on a baking sheet in a single layer and bake the stuffed mushrooms at 400°F for 10 minutes. Remove from the oven, top with the walnuts, and return to the oven to bake for an additional 10 minutes. Allow the mushrooms to cool for 5 minutes before serving. Optional: garnish with small fresh sage leaves or chopped sage. 

recipe tips for the best results

• The number of mushrooms will vary based on the size of the mushroom caps. I typically use baby bella mushrooms (also called crimini), which have a rich, earthy flavor and are perfect for bite-sized starters. With that size, I usually get about 12-16 stuffed mushrooms.

• The stuffed mushrooms may wobble a little bit on your baking sheet. Carefully transfer them to the oven to prevent any from tipping over. You can also bake them in a large baking dish, too.

• If you want to easily chop up the stuffing ingredients, you can throw the garlic, sage, red onion and celery into the food processor and pulse it a few times until it's chopped.

keto sausage stuffed mushrooms variations

• Feel free to use a spicy sausage or a mild Italian sausage if you'd like.

• For different flavors variations, you can add other spices like Italian seasoning, a pinch of red pepper flakes (for a medium heat), or an even more generous amount of tasty garlic.

• Change up the toppings! I love walnuts on these keto stuffed mushrooms but you could also use a different kind of toasted nut, crumbled bacon, or even a bit of parmesan cheese or mozzarella cheese if you'd like them to have a cheesy, bubbly crust.

• I prefer cremini mushrooms for this keto stuffed mushrooms recipe but you can also use white mushrooms (also called white button mushrooms) too.

With only five net carbs per serving, this low-carb appetizer is a crowd-pleaser for all eaters! It is so simple, elegant and easy to make. My kind of holiday recipe. 😉 I hope you love them too.
