Italian Vegetarian Stuffed Mushrooms Recipe
Introduction
Italian Vegetarian Stuffed Mushrooms are a delightful appetizer or side that combines earthy mushrooms with a savory blend of herbs, garlic, and parmesan. This easy-to-make recipe is perfect for gatherings or a flavorful weeknight treat.

Ingredients
- 12 whole mushrooms (about 2 inches in diameter, small portobello preferred)
- 1/4 cup extra-virgin olive oil (divided)
- 1/4 cup shallots (finely diced, or onion)
- 2 cloves garlic (minced)
- 3 tablespoons fresh parsley (finely chopped, plus more for garnish)
- 1/2 cup breadcrumbs
- 1/4 cup parmesan cheese (fresh grated)
- 1/2 teaspoon dried oregano (or 1 teaspoon finely chopped fresh)
- Kosher salt (to taste)
- Black pepper (to taste)
Instructions
- Step 1: Gently wipe mushrooms clean with a kitchen or paper towel, avoiding water to maintain texture.
- Step 2: Remove mushroom stems, discard tough ends, and finely chop the remaining stem pieces.
- Step 3: Heat a skillet over medium heat and add 2 tablespoons of olive oil.
- Step 4: Add the shallots, garlic, chopped mushroom stems, and parsley to the skillet with a pinch of salt. Cook, stirring occasionally, until softened, about 5-7 minutes.
- Step 5: In a medium bowl, combine the sautéed mixture with breadcrumbs, parmesan cheese, oregano, and salt and pepper to taste.
- Step 6: Place mushroom caps in a baking dish and stuff each with the mixture, pressing down firmly. Some stuffing may fall off and that’s okay.
- Step 7: Drizzle the remaining 2 tablespoons of olive oil over the stuffed mushrooms.
- Step 8: Cover the baking dish with foil. At this point, you can refrigerate for up to a day before baking.
- Step 9: Bake at 375 degrees Fahrenheit for 20 minutes. Remove the foil and bake an additional 10-15 minutes until golden and bubbling.
- Step 10: Serve the stuffed mushrooms hot or warm, garnished with extra parsley if desired.
Tips & Variations
- Use fresh parmesan cheese for the best flavor and meltability.
- Substitute shallots with finely diced onion if needed.
- For a vegan version, replace parmesan with a vegan cheese or nutritional yeast.
- Add finely chopped sun-dried tomatoes or olives to the stuffing for extra flavor.
- Be sure not to wash mushrooms with water; wiping them keeps their texture intact.

Ingredients
Mushrooms
- 12 whole mushrooms (about 2 inches in diameter, small portobello mushrooms)
Stuffing
- 1/4 cup extra-virgin olive oil (divided)
- 1/4 cup shallots (finely diced, or onion)
- 2 cloves garlic (minced)

- Black pepper (to taste)
Instructions
- Prepare Mushrooms: Gently wipe off any excess dirt from the mushrooms with a clean kitchen or paper towel without washing them with water to maintain texture.
- Chop Stems: Remove the stems from the mushrooms by cutting off and discarding the tough ends. Finely chop the stems for the stuffing mixture.
- Heat Skillet: Heat a nonstick skillet over medium heat and add 2 tablespoons of olive oil.
- Sauté Ingredients: Add shallots, garlic, chopped mushroom stems, and parsley to the skillet with a pinch of salt. Cook, stirring occasionally, until softened, about 5-7 minutes.

- The stuffing can be prepared a day ahead and refrigerated before baking to save time.
- For a gluten-free option, substitute breadcrumbs with gluten-free breadcrumbs.
- These mushrooms are best served warm to enjoy the melted cheese and aromatic filling.
