Make Vegetarian Stuffed Mushrooms: A Simple Method

Step 1: Prepare the Mushrooms
Start by preheating your oven to 375°F (190°C). Clean the large white mushrooms with a damp cloth to remove any dirt. Carefully remove the stems, setting them aside for later. You’ll want to leave the mushroom caps intact to hold the filling.
Step 2: Chop the Filling Ingredients
Finely chop the reserved mushroom stems, red bell pepper, onion, and green onions. You want these to be small enough to fit nicely into your mushroom caps.
Step 3: Sauté the Vegetables
In a large skillet, heat the olive oil over medium heat. Add the chopped onions and sauté until translucent. Then, add the red bell pepper, chopped mushroom stems, and green onions, cooking for an additional 5 minutes until softened. Stir in the oregano, salt, and pepper, mixing well.
Step 4: Combine with Cheese and Breadcrumbs
In a mixing bowl, combine the sautéed vegetables with the roasted red bell pepper, breadcrumbs, grated Parmesan cheese, and chopped parsley. Mix until everything is well coated and combined.
Step 5: Stuff the Mushrooms
Using a spoon, fill each mushroom cap generously with the vegetable mixture. Don’t be shy—pack it in there!
Step 6: Bake to Perfection
Place the stuffed mushrooms on a baking sheet and bake in the preheated oven for 20–25 minutes, or until they are golden brown and the mushrooms are tender.
Step 7: Serve and Enjoy
Once cooked, remove the mushrooms from the oven and let them cool for a few minutes. Serve them warm, garnished with extra parsley if desired. These Vegetarian Stuffed Mushrooms are sure to be a hit!
Spring–Summer–Fall–Winter Ideas

- Spring: Add fresh asparagus tips to the filling for a seasonal touch.
- Summer: Use fresh garden tomatoes instead of roasted red bell peppers for a juicy twist.
- Fall: Incorporate chopped walnuts or pecans for a nutty flavor and added crunch.
- Winter: Mix in some dried cranberries for a sweet contrast to the savory filling.
Chef’s Notes
- Feel free to experiment with different types of cheese, such as feta or mozzarella, for varied flavor profiles.
- If you prefer a bit of spice, add red pepper flakes to the filling.
- For a vegan version, substitute the Parmesan cheese with nutritional yeast and use vegan breadcrumbs.
- Try adding spinach or kale to the filling for an extra nutrient boost.

Vegetarian Stuffed Mushrooms Q&A
Can I make these stuffed mushrooms ahead of time?
Absolutely! You can prepare the filling and stuff the mushrooms a day in advance. Just cover them and store them in the refrigerator until you’re ready to bake them.
What type of mushrooms work best for stuffing?
Large white mushrooms are ideal because they have a sturdy cap that holds up well to the filling. However, you can also use portobello mushrooms for a heartier option.
Can I customize the filling?
Yes! The filling can be customized to suit your taste. Feel free to add different vegetables, spices, or even grains like quinoa or rice for added texture and nutrition.

The mushrooms should be tender and the tops should be golden brown. If you poke them gently with a fork, they should yield easily without being mushy.
