These keto stuffed mushrooms are the party bites everyone reaches for first. Creamy, cheesy, and stuffed with sausage, they deliver big flavor and come out irresistible straight from the oven.
Holly’s Recipe Highlights
- Flavor: Each bite is rich and savory, with juicy sausage, tangy sun-dried tomatoes, and a cheesy filling that melts in your mouth.
- Recommended Tools: You’ll need a 10-inch skillet, a mixing bowl, a small spoon for filling the mushrooms, and a rimmed baking sheet for baking them to golden perfection.
- Serving Suggestions: I love serving these as a keto appetizer, snack plate, or game-day finger food, and every time I make them for a party, they disappear from the tray almost as fast as I can set them down.
Assemble Your Ingredients
- Mushrooms: Choose firm, dry mushroom caps and avoid cracked or slimy ones. Cremini (brown) mushrooms have a slightly deeper flavor.
- Sausage: Mild or hot sausage works. If using plain ground pork, add extra Italian seasoning and a pinch of salt.
- Cheese: Softened, full-fat cream cheese gives the filling a smooth, scoopable texture and the best richness. Use low-moisture mozzarella for meltability.
- Tomatoes: Drain well and chop fine to avoid oily pockets.
- Variations: Skip the sundried tomatoes for a more classic sausage-cheese filling. Add very well-drained chopped spinach for a “Tuscan” twist, or swap the sausage for cooked crumbled bacon or chopped pepperoni for a fun flavor change.
How to Make Keto Stuffed Mushrooms
- Clean mushrooms and scoop out the cap. Dice the stems.
- Cook the mushrooms, sausage, and garlic in a skillet.
- Mix the cream cheese, cheese mixture, sausage, tomatoes, and seasoning.
- Fill each mushroom with the mixture. Bake (full recipe below).
Holly’s Pro Tips for Perfect Caps
- Wipe mushrooms clean to keep caps from getting waterlogged.
- Scrape just a little from each cap to avoid tearing and shrinking.
- Let the sausage mixture cool so it doesn’t melt the cream cheese.
- Drain sausage fat for a thick, scoopable filling that holds.
- For neat filling, pipe the mixture into caps using a bag with a snipped corner.
- Broil 1–2 minutes at the end for a deeper golden top, watching closely.
Storing Leftovers
- Storage: Keep leftovers in an airtight container in the refrigerator for up to 4 days.
- Reheating: Warm in the oven or air fryer at 350°F until hot and the tops re-melt, about 6–10 minutes.
- Freezing: Best to freeze unbaked stuffed caps. Freeze on a tray until solid, then transfer to a freezer bag for up to 4 months. Bake from frozen, adding a few extra minutes, until tender and bubbly.
- Make-Ahead: Stuff up to 24 hours ahead and refrigerate. Add the final cheese topping just before baking.

Keto Stuffed Mushrooms
Mushroom caps stuffed with creamy Italian sausage, sun-dried tomatoes, and a mozzarella-parmesan topping baked until golden.
Equipment
Ingredients
- 24 medium mushrooms white or brown, or 48 small mushrooms
- 8 ounces ground Italian sausage
- 2 cloves garlic
- ½ cup shredded mozzarella cheese divided
- ¼ cup shredded parmesan cheese divided
- 4 ounces cream cheese softened
- ¼ cup sun-dried tomatoes in oil drained and finely chopped
- 2 tablespoons fresh chopped parsley
- 1 teaspoon Italian seasoning
- ¼ teaspoon pepper
Instructions
- Preheat oven to 400°F.
- Wipe the mushrooms clean with a damp paper towel. Separate the stems from the caps.
- Using a small spoon, gently scrape out a little of the inside of each cap to create a shallow well for the filling. Finely dice the stems and any extra mushroom bits you removed.
- In a 10-inch skillet over medium-high heat, cook the sausage, garlic, and chopped mushroom stems until the sausage is browned and no pink remains. Drain off any excess fat and let the mixture cool slightly.
- In a small bowl, combine the mozzarella and Parmesan. Set aside ½ cup of this mixture for topping.
- In a medium bowl, mix together the cream cheese, the remaining mozzarella-Parmesan mixture, the cooled sausage mixture, sun-dried tomatoes, parsley, Italian seasoning, and pepper until well combined.
- Fill each mushroom cap with the cream cheese mixture and arrange on a rimmed baking sheet. Sprinkle the reserved ½ cup cheese over the tops.
- Bake for 18–20 minutes, or until the mushrooms are tender and the cheese is melted and golden.
Notes
