There are many wonderful ways to enjoy mushrooms on a healthy low carb diet. You can blend them into a creamy keto mushroom soup, or add them to cauliflower risotto. And they are simply divine paired with tender pork medallions.

But these cheese stuffed mushrooms are one of my favorite keto appetizers. These tender baked mushrooms have a melty cheddar filling and a hint of fresh sage. They are steakhouse quality!

I made these for a much needed stay-at-home date night dinner with my husband. We gathered together a collection of appetizers and charcuterie and sat down together to watch a movie.

And the moment I popped one of these cheese stuffed mushrooms in my mouth, I was in pure heaven. I could have eaten the whole batch and called it dinner. Except my husband loved them too so I had to share. Bummer!

Why you will love this recipe

Have you ever wondered why so many stuffed mushroom recipes call for breadcrumbs? The filling really doesn’t need them to have a good consistency. It’s just unnecessary filler, in my opinion.

This recipe uses the mushroom stems as part of the filling, which gives it great consistency, as well as more intense mushroom flavor. And there’s less waste!

I recommend using a good, flavorful cheese like Cabot Seriously Sharp, as it complements the umami of the mushrooms. A little garlic and sage or thyme brings it all together.

And these delicious keto stuffed mushrooms have only 4.3g net carbs per serving. So they are an appetizer you can feel good about serving any time you want!

Ingredients you need

Top down image of ingredients needed for Cheese Stuffed Mushrooms.

Button or crimini mushrooms: Try to pick mushroom caps of a decent size. The really small ones are hard to fill with much of the cheesy stuffing.
Butter: Use salted butter to cook the mushroom stems, garlic and sage. It also adds great flavor.
Garlic: I prefer using fresh garlic because it adds so much more flavor than garlic powder. But you could use garlic powder if you don’t have fresh.
Fresh sage: If you can’t get fresh sage, use about ½ teaspoon dried ground sage in the filling instead. You can also use fresh thyme or basil.
Cream cheese: Full fat cream cheese adds a rich melty quality to the filling.
Sharp white cheddar: The sharpness of a good cheddar balances out the mild cream cheese.
Salt and pepper

Step-by-step directions

Brush the mushrooms with a damp cloth to remove any dirt, then remove the stems from the mushroom caps. Finely dice the stems but keep the mushroom caps whole.
In a medium skillet over medium heat, melt the butter. Add the diced mushroom stems and garlic, and saute until tender and fragrant, about 3 minutes.
Stir in the sage and season with salt and pepper. Saute one more minute, then remove from heat and let cool 5 minutes.
In a large bowl, combine the cream cheese, grated cheddar, and sautéed mushroom mixture. Use a rubber spatula to mix well.
Spoon the mixture into the mushroom caps, pressing in to fill the whole cavity. Place in a greased large glass or ceramic baking dish and bake at 350ºF until the cheese is bubbling and melted, and the mushrooms are tender, 15 to 20 minutes.
Remove and let cool 10 minutes, then sprinkle with chopped sage before serving.

Expert tips

One of the best part about these cheese stuffed mushroom is that you can scale up or down, according to how many you want. Make a half batch for a small family group, or a double batch for a big party.

To remove the stems, just gently pull and twist, and they should come right out in one piece. They give the filling more volume and some more of that delicious umami flavor. Chop them up finely, and sauté with garlic and butter.

Use a small spoon to pack as much of the cheesy filling as you can into each mushroom cap. You can mound any extra on top as well.

Bake your mushrooms in a glass or ceramic dish. Metal conducts heat more efficiently but the bottoms of your mushroom caps may brown too quickly.

Once the cheese filling is melted and lightly browned on top, they should be done. You don’t want to overcook them, as the mushrooms soften too much and are hard to pick up.
