How to Make White Cheddar Stuffed Mushrooms Recipe
Step 1: Prepare the Mushrooms
Start by cleaning your mushroom caps gently with a damp cloth to remove any dirt. Carefully remove the stems, then finely chop them for the filling. This sets the stage for a flavorful, tender bite and ensures the caps are perfectly ready for stuffing.
Step 2: Sauté Aromatics and Mushroom Stems
In a skillet over medium heat, melt the butter and add the chopped mushroom stems, minced garlic, and finely chopped onion. Sauté these together for about 4 to 5 minutes until everything softens and releases a mouthwatering aroma. This step infuses the filling with deep, savory notes that elevate the dish.
Step 3: Mix the Filling
Once the sautéed mixture cools slightly, stir in the bread crumbs, dried thyme, salt, and black pepper. Then fold in the shredded white cheddar, Parmesan, and fresh parsley. This combination creates a rich, cheesy filling with a perfect herby and savory balance, ready to be spooned into the mushrooms.
Step 4: Stuff and Bake
Generously fill each mushroom cap with the cheesy mixture, pressing down gently to pack it in. Place the stuffed mushrooms on a lightly greased baking sheet arranged in a single layer. Bake in a preheated 375°F (190°C) oven for 18 to 20 minutes until the mushrooms are tender and the filling turns golden and bubbly. This final step seals in those delicious flavors and gives a beautiful, appetizing finish.
How to Serve White Cheddar Stuffed Mushrooms Recipe

Garnishes
A sprinkle of additional chopped fresh parsley or a light dusting of grated Parmesan just before serving adds a pop of color and an extra layer of flavor. For a touch of elegance, drizzle a tiny bit of high-quality olive oil or a squeeze of fresh lemon over the mushrooms to brighten their richness.
Side Dishes
This White Cheddar Stuffed Mushrooms Recipe pairs wonderfully with fresh green salads, crusty bread, or a light soup. Their rich and creamy nature also makes them a fantastic complement to roasted vegetables or grilled meats, balancing out your meal with their cheesy, earthy charm.
Creative Ways to Present
For parties or special gatherings, serve these stuffed mushrooms on a decorative platter lined with fresh herbs like thyme or rosemary sprigs. You can also skewer them on cocktail picks for easy nibbling or present them in a warm cast-iron skillet straight from the oven to impress your guests with rustic charm.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store them in an airtight container in the refrigerator for up to 3 days. The flavors will develop even more overnight, making them just as delicious when reheated gently.
Freezing
You can freeze these stuffed mushrooms before baking. Arrange them on a parchment-lined tray and freeze until firm, then transfer to a freezer bag. Freeze for up to 2 months. When ready to enjoy, bake directly from frozen, adding a few extra minutes to the cooking time to ensure they heat through fully.
Reheating
Reheat your leftovers or frozen cooked stuffed mushrooms in a preheated oven at 350°F (175°C) for about 10 minutes, or until warmed through. Avoid microwaving when possible to preserve their texture and prevent the cheese from becoming rubbery.
FAQs
Can I use other types of mushrooms?
Absolutely! While white button mushrooms are classic for this recipe, you can try cremini or portobello caps for a deeper flavor and meatier texture. Just adjust baking times slightly for larger mushrooms.
Is there a way to make this recipe vegan?
Yes! Swap the butter for plant-based margarine, use vegan breadcrumbs, and replace white cheddar and Parmesan with your favorite vegan cheese alternatives. The filling will still be deliciously flavorful.
Can I add other ingredients to the filling?
Definitely! You might consider mixing in cooked sausage, chopped nuts for crunch, or sun-dried tomatoes for a twist. Just keep the overall balance so the stuffing remains cohesive and tasty.
How do I keep the mushrooms from becoming soggy?
Sautéing the stems and thoroughly cooking the filling reduces moisture, while baking at a higher temperature helps evaporate excess liquid. Using dry breadcrumbs also helps absorb any moisture released during cooking.
What’s the best way to clean mushrooms for this recipe?
Use a damp paper towel or mushroom brush to gently wipe the mushrooms clean. Avoid soaking them in water as mushrooms absorb moisture quickly, which can affect texture and cooking.
