Ingredients
You'll only need a few simple ingredients to make these keto stuffed mushrooms. The exact measurements are listed in the recipe card below. Here's an overview of what you'll need:
- Cream cheese: This is the base of the filling. Reduced-fat cream cheese works if that's what you have on hand, but I do recommend using full-fat cream cheese for the best flavor and texture.
- Seasonings: I use kosher salt, garlic powder, onion powder, dried thyme, and cayenne pepper.
- Mushrooms: I like to use Cremini mushrooms. White mushrooms work too. It's best to use large mushrooms in this recipe and make them about the same size. I often buy two containers of mushrooms, so that I can pick the best ones for this recipe.
- Shredded cheese: Gruyere is amazing and it's what I like to use in this recipe. But if you can't get gruyere, white cheddar works too.
Variations
- As mentioned above, you can use white mushrooms instead of cremini mushrooms.
- Try using a combination of soft goat cheese, oregano, and white cheddar instead of cream cheese, sage, and gruyere. It's a different flavor profile, but it's just as good.
- You can add a bit of crunch by sprinkling the mushrooms with almond flour or crushed pork rinds before baking.
- Another tasty addition that I love is mixing bacon bits into the cream cheese mixture.
- You can stuff the mushrooms with this tasty cream cheese dip.
Keto Stuffed Mushrooms Instructions
Scroll down to the recipe card for detailed instructions. Here are the basic steps for making this recipe:
Your first step is to prepare the mushrooms. Wipe them clean, then use a paring knife to remove the stems.
Now, mix the filling ingredients in a bowl - that's the cream cheese, spices, and shredded gruyere.
You'll want to pack the filling into each mushroom cavity, then arrange them in a single layer on a rimmed baking dish.
The last step is to bake the mushrooms until the cheese has melted and the mushrooms are tender - this should take 10-15 minutes in a 400°F oven.
Expert Tip
Mushrooms should be cleaned before cooking, but it's best to use a damp paper towel to wipe them clean rather than rinse them in water. If you wash them, they'll absorb the water and become soggy.
If they appear very dirty and you feel that they really should be washed, do it quickly, right before cooking them, and before you remove the stems. And whatever you do, do not soak them in water.
Recipe FAQs
As mentioned above, one trick is to avoid washing them under running water. Instead, use damp paper towels to wipe them clean.
The second trick is to bake the mushrooms in a hot oven and avoid overcooking them. The longer they are baked, the more water they'll release.
Yes! You can make these mushrooms ahead of time, refrigerate them, and then reheat them in a 350F oven for about 10 minutes. You can also briefly microwave them.
While most similar recipes use breadcrumbs, I don't think they're needed. These mushrooms are so full of flavor and their texture is perfect.
If you'd like to add something crunchy, you can use crushed pork rinds. But I truly don't think that's necessary.
Serving Suggestions
These tasty mushrooms make a great appetizer, although I often make them for my family as a side dish.
In fact, they are so good and so filling, that sometimes I make them as my entire lunch!
When I serve them as a side dish, I like to serve these tasty mushrooms with a main dish that I can cook in the same 400°F oven.
So I tend to serve them with baked drumsticks, baked chicken thighs, pork meatballs, or baked shrimp.
Storing Leftovers
You can keep the leftovers in the fridge, in an airtight container, for up to 4 days. Reheat them in the microwave, covered, at 50% power.
I don't recommend freezing the leftovers. Their texture and flavor won't survive freezing and thawing.

Keto Stuffed Mushrooms
Ingredients
- 2 oz cream cheese softened
- ¼ teaspoon Diamond Crystal kosher salt or a pinch of any other salt
- ¼ teaspoon garlic powder
- ¼ teaspoon onion powder
- â…› teaspoon dried thyme
- â…› teaspoon cayenne pepper
- 3 oz gruyere cheese grated (¾ cup)
- 12 large Cremini mushrooms (8 oz)
Instructions
- Preheat your oven to 400°F. Grease a glass or ceramic baking dish (a square 8-inch baking dish should work).
- Wash and dry the mushrooms. Use a paring knife to gently remove the stems, as shown in the video below. You’ll be left with about 6 oz of mushrooms after removing the stems.
- In a medium bowl, use a rubber spatula to thoroughly mix the cream cheese with the salt and the spices. Mix in the gruyere.
- Spoon the mixture into the mushroom caps. Pack about a teaspoon into the cavity, then add a small mound on top of the mushroom. You can use your hands to pack the mound in and shape it so that it’s smooth. You might be left with a bit of unused cheese mixture. If you had additional mushrooms in the package, you can stuff them too.
- Place the mushrooms in the prepared baking dish. Bake until the cheese has melted and the mushrooms are tender, 10-15 minutes.
- Place the stuffed mushrooms on paper towels to absorb extra liquids. Let them cool for 5 minutes before serving.

I was surprised that these were so easy to make. And they were delicious! I made them for a dinner party and every single guest asked for the recipe, and they're not even doing keto. 🙂
