Pizza Stuffed Mushrooms: New Favorite Appetizer!
Ingredients
- 1/2 lb ground Italian Sausage
- 1/2 cup (about 3 ounces) chopped pepperoni
- 1/3 cup chopped onion
- 2 cloves garlic, minced
- 1 (8 ounce) package cream cheese, softened
- 1/2 cup pizza sauce
- 1/2 teaspoon dried oregano
- 24 white button mushrooms, wiped clean and stems removed
- 1/4 cup grated Parmesan
- 3/4 cup shredded Mozzarella
Instructions
- Preheat oven to 350 degrees F. Line a baking sheet with foil or use a mini muffin tin to cook the mushrooms.
- In a large skillet, cook the sausage, pepperoni, and the onion over medium heat for 5-6 minutes or until the sausage is no longer pink. Drain.
- Reduce heat to low. Add the cream cheese, pizza sauce, and oregano to the skillet. Stir and cook until melted. Stir in the Parmesan and remove from the heat.
- Spoon a heaping tablespoon of mixture into each mushroom cap (a cookie dough scoop works well here) and place on baking sheet.
- Bake mushrooms for about 15 minutes or until mushrooms are tender. Remove from oven and top the mushrooms with mozzarella and additional chopped pepperoni (for looks) if desired. Return to the oven for 2-4 minutes or until cheese is melted.

Notes
– For a richer flavor, use hot Italian sausage. If you prefer less spice, mild Italian sausage works just as well.
– If you’re concerned about food safety with pork, ensure the internal temperature of the sausage reaches 160°F (71°C) before adding other ingredients to the skillet.
– These can be assembled up to 24 hours ahead of time and refrigerated. Bake as directed, adding 5 minutes to the initial bake time. Nutrition information is an estimate, calculated automatically. Values vary with brands, substitutions and portion sizes.
The technique that makes it
The success of pizza stuffed mushrooms relies on the proper handling of the mushroom caps and the filling’s flavor balance. The mushrooms should be wiped clean to maintain their moisture while avoiding excess water. When sautéing the sausage, onion, and garlic, controlling the heat is crucial to achieve the Maillard reaction, which enhances the overall flavor profile. This technique caramelizes the natural sugars in the ingredients, creating a deep, rich flavor that complements the cream cheese and pizza sauce. Additionally, incorporating the cream cheese at room temperature ensures a smooth emulsion, allowing the filling to bind together well and adhere to the mushrooms without being too runny.
Troubleshooting
- Filling too runny: If your filling is too loose, consider adding more cream cheese or a bit of breadcrumbs to absorb excess moisture.
- Mushrooms releasing too much water: Ensure you wipe the mushrooms clean instead of soaking them. Also, pre-baking the mushroom caps for a few minutes can help reduce moisture.
- Filling not flavorful enough: Increase the seasoning by adding more oregano or crushed red pepper flakes to enhance the flavor profile.
- Cheese not melting properly: Make sure the cheese is shredded and evenly distributed in the filling. Baking at the right temperature (around 375°F) will help achieve that perfect melt.
Substitutions
- Italian sausage: Swap with ground turkey or chicken for a leaner option without sacrificing flavor.
- Pepperoni: Use diced salami or prosciutto for a different flavor profile while maintaining a similar texture.
- Cream cheese: Substitute with ricotta cheese for a lighter filling, but be mindful that it may alter the texture slightly.
- Pizza sauce: Use marinara or a homemade tomato sauce for a more robust flavor if desired.
Pro tips
- Don’t overcrowd the baking sheet; give the mushrooms space to cook evenly and get tender.
- For a richer flavor, use hot Italian sausage. If you prefer less spice, mild Italian sausage works just as well.
- If you’re concerned about food safety with pork, ensure the internal temperature of the sausage reaches 160°F (71°C) before adding other ingredients to the skillet.
- These can be assembled up to 24 hours ahead of time and refrigerated. Bake as directed, adding 5 minutes to the initial bake time.
These pizza stuffed mushrooms are a fantastic appetizer that combines the best of two worlds. Experiment with different cheeses or add a pinch of red pepper flakes for an extra kick. Enjoy!
