Ingredients
Gather these simple ingredients to create your incredible cheese stuffed mushroom appetizer:
- 24 cremini mushrooms, 1½” to 2″ diameter (about 12-14 ounces total)
- 2 tablespoons unsalted butter
- 2 tablespoons minced yellow onion
- 2 tablespoons minced garlic
- 1 tablespoon olive oil
- 1 teaspoon Morton kosher salt
- ½ teaspoon black pepper
- 2 ounces shredded whole milk mozzarella
- ¼ cup + 1 teaspoon grated Parmesan, divided
- 2 tablespoons breadcrumbs
- 1 tablespoon chopped fresh thyme leaves, plus more for garnish
Notes & Substitutions: Cremini mushrooms, also known as baby bellas, offer a richer, earthier flavor than white button mushrooms, though either works well. Beyond their rich flavor, research from UCLA Health highlights the health benefits of mushrooms, including their potential to lower cancer risk and boost vitamin D. For fresh herbs, feel free to swap thyme for parsley or chives, adjusting to your preference. Other cheeses like provolone, sharp cheddar, or even a creamy goat cheese can replace or supplement mozzarella for different flavor profiles. You can use homemade breadcrumbs for a fresher texture, or store-bought panko for extra crispness.
Equipment
You won’t need many special tools for this recipe. Here’s what you’ll use:
- Oven-safe skillet (a 12″ cast iron skillet is ideal) or a baking dish
- Mixing bowl
- Measuring spoons and cups
- Cutting board
- Sharp knife
- Damp paper towel
Instructions
Creating these perfect cheese stuffed mushrooms is a straightforward process. Follow these steps for best results:
- Preheat Oven and Prep Mushrooms: Preheat your oven to 375°F (190°C). Gently brush the mushrooms clean with a damp paper towel. Carefully remove the stems from the mushroom caps and finely mince the stems.
- Sauté Aromatics: Melt the unsalted butter in a medium skillet over medium heat. Add the minced yellow onion and the minced mushroom stems. Cook, stirring occasionally, until the onions become soft and translucent, which takes about 5 minutes. Stir in the minced garlic and cook for just 1 more minute until fragrant. Make sure the onion and garlic do not brown. Transfer this aromatic mixture to a large, low, wide bowl and set it aside to cool completely.
- Season Mushroom Caps: While the filling cools, arrange the clean mushroom caps in your 12″ cast iron skillet or another oven-safe baking dish. Drizzle olive oil evenly over the tops of the caps. Gently toss the mushrooms to coat them thoroughly. Arrange the caps cavity-side-up in the skillet. Sprinkle the mushroom caps evenly with kosher salt and black pepper.
- Prepare Stuffing: Once the onion and mushroom stems mixture has cooled completely, add the shredded whole milk mozzarella, ¼ cup of the grated Parmesan cheese, breadcrumbs, and chopped fresh thyme leaves to the bowl. Fold all the ingredients together thoroughly until they are evenly combined.
- Stuff and Top: Divide the savory stuffing mixture evenly among the prepared mushroom caps. Press the stuffing firmly into each cap and mound it slightly on top, using all of the mixture. Finish by sprinkling the remaining 1 teaspoon of grated Parmesan cheese over the stuffed mushrooms. This will create a beautiful golden crust.
- Bake: Place the skillet containing the stuffed mushrooms into your preheated oven. Bake for approximately 20 minutes, or until the mushrooms are softened, the mozzarella cheese is wonderfully melty and bubbly, and the Parmesan on top is lightly browned and golden.
- Garnish and Serve: Carefully remove the skillet from the oven. Serve your delicious cheesy stuffed mushrooms hot or warm. Garnish with additional fresh thyme leaves sprinkled over the top before serving.
Pro Tips & Troubleshooting
- Mushroom Selection: Choose cremini mushrooms that are uniform in size, ideally 1½ to 2 inches in diameter. This ensures even cooking and perfect two-bite appetizers.
- Stuffing Generously: Don’t be shy with the filling. Press the stuffing firmly into the caps and mound it slightly to maximize flavor in every bite of your cheese stuffed mushroom.
- Prevent Watery Mushrooms: Sautéing the mushroom stems thoroughly before mixing with the other ingredients helps release their moisture. Also, avoid overcrowding the baking dish, as this can steam the mushrooms instead of roasting them.
- Flavor Enhancers: For an extra layer of complexity, add a tiny dash of dry white wine, like Sauvignon Blanc, to the mushroom and onion mixture as it sautés. Cook until the wine has evaporated.
- Don’t Overcook: Bake until the mushrooms are tender but not mushy. Overcooked mushrooms can become rubbery.
- Achieve Golden Tops: If your cheese isn’t as golden as you’d like after baking, you can broil the stuffed mushrooms for 1-2 minutes. Watch them closely to prevent burning.
Serving, Storage, & Variations
These cheese stuffed mushrooms are incredibly versatile.
Serving Suggestions:
- Appetizer: Serve them warm as a standalone finger food, or pair them with other party favorites like bruschetta or mini quiches.
- Side Dish: They make an elegant accompaniment to main courses such as grilled steak, roasted chicken, or pork tenderloin.
Storage Instructions: Store any leftover baked stuffed mushrooms in an airtight container in the refrigerator for up to 3-4 days. Reheat gently in the oven or microwave until warmed through.
Freezing Instructions: You can freeze baked cheesy stuffed mushrooms. Arrange them in a single layer on a baking sheet and freeze until solid. Transfer them to a freezer-safe bag or container and freeze for up to 2 months. Thaw in the refrigerator overnight, then reheat in a 350°F (175°C) oven until hot. You can also freeze uncooked stuffed mushrooms in the same way; bake from frozen, adding an extra 10-15 minutes to the baking time.
Variations:
- Meaty: For a heartier bite, add crumbled cooked sausage (mild or spicy), crispy bacon bits, or finely diced cooked ham to the stuffing mixture.
- Spicy: Introduce a pinch of red pepper flakes to the sautéed aromatics for a subtle kick.
- Herbaceous: Experiment with different fresh herbs like finely chopped rosemary or oregano for varying flavor profiles.
- Gluten-Free: Simply substitute regular breadcrumbs with your favorite gluten-free breadcrumbs.
- Grilled: For a smoky flavor, try grilling these stuffed mushrooms on a cedar plank or directly over medium heat until tender and charred.

FAQ
- What are the best mushrooms for stuffing? Cremini (baby bella) or white button mushrooms are ideal. Look for mushrooms that are 1½ to 2 inches in diameter, as they are the perfect size for holding the stuffing and cooking evenly.
- Can I make cheese stuffed mushrooms ahead of time? Yes, absolutely! You can prepare and stuff the mushrooms up to a day in advance. Store the uncooked, stuffed mushrooms in an airtight container in the refrigerator until you are ready to bake them.
- How do you prevent stuffed mushrooms from getting watery? Sautéing the mushroom stems thoroughly releases much of their moisture before adding them to the stuffing. Also, avoid overcrowding your baking dish, which can cause the mushrooms to steam rather than roast, leading to excess water.
- Can I freeze leftover stuffed mushrooms? Yes, you can freeze both uncooked and baked stuffed mushrooms. Freeze them in a single layer on a baking sheet until solid, then transfer to a freezer-safe bag. Bake from frozen, adding extra time, or thaw overnight before reheating.
