Print Recipe

Juicy mushrooms stuffed with garlicky Italian sausage, cream cheese, herbs, and melty mozzarella. These low-carb stuffed mushrooms are rich, cheesy, and perfect for dinner, meal prep, or party appetizers. No breadcrumbs, no weird substitutes, just real food packed with flavor.

Ingredients

For the Mushrooms:

  • 20–24 medium white or cremini mushrooms

  • 1 tbsp olive oil

  • Pinch of salt

For the Filling:

  • 1 lb Italian sausage (mild or hot, casing removed)

  • 4 cloves garlic, minced

  • 1/2 yellow onion, finely chopped (optional)

  • Mushroom stems, chopped

  • 1/2 tsp fennel seeds, crushed

  • 1/4 tsp red pepper flakes

  • 1 tsp dried oregano

  • 1/2 tsp black pepper

  • Salt, to taste

  • 4 oz cream cheese (softened)

  • 1/2 cup shredded mozzarella cheese

  • 1/4 cup grated parmesan cheese

Topping:

  • Extra mozzarella & parmesan

  • Chopped fresh parsley or basil (optional)

  • Olive oil drizzle

Instructions

  • Prep Mushrooms: Wipe mushrooms clean, remove stems, and gently hollow out caps. Set stems aside.

  • Bake Caps: Drizzle mushroom caps with olive oil and a little salt. Bake at 375°F (190°C) for 10 minutes.

  • Make Filling: In a skillet, brown sausage over medium heat. Add garlic, onion, chopped stems, fennel seed, red pepper flakes, oregano, and pepper. Cook until soft and browned.

  • Creamy Mix: Lower heat. Stir in cream cheese until melted, then mix in mozzarella and parmesan. Adjust salt.

  • Stuff: Spoon filling into each mushroom cap. Top with extra cheese and a light drizzle of olive oil.

  • Bake: Bake stuffed mushrooms at 375°F for 15–18 minutes until cheese is golden and bubbling.

  • Rest & Serve: Let rest 5 minutes. Sprinkle with herbs and serve warm.

Notes

  • Use smaller mushrooms for appetizers, larger ones for a full meal.

  • Filling can be made ahead and stored in the fridge up to 2 days.

  • To reheat, use an oven or air fryer for best texture.

  • Not freezer-friendly due to cream cheese.

  • Skip onions for stricter keto macros.
