Ingredients
Before you begin, gather the following ingredients. This list makes about 24 stuffed mushrooms, perfect for sharing at a party or family dinner.
- 24 large cremini or white mushrooms (stems reserved and finely chopped)
- 2 cups mashed potatoes (homemade or store-bought, cold or room temperature work best)
- 1 cup cooked wild rice
- 2 tablespoons olive oil
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 1/2 cup grated parmesan cheese (or pecorino, or your preferred hard cheese)
- 1/4 cup chopped fresh parsley (or other fresh herbs like thyme, chives, or dill)
- 1/3 cup sour cream or Greek yogurt (adds tang and moisture)
- Salt and freshly ground black pepper, to taste
- 2 tablespoons melted butter (for brushing the mushrooms and topping)
- Optional: 1/4 cup chopped toasted walnuts or pecans, for added crunch
- Optional garnish: fresh chives, parsley, or a dusting of smoked paprika
Step-by-Step Instructions
1. Prepare the Mushrooms
- Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it.
- Gently clean the mushrooms with a damp paper towel. Twist off the stems—reserve and finely chop these for the filling.
- Arrange the mushroom caps, stem-side up, on the prepared baking sheet. Lightly brush the outsides (and insides, if desired) with melted butter or olive oil. Sprinkle them lightly with salt.
2. Sauté Aromatics
- Heat olive oil in a skillet over medium heat. Add the chopped onion and a pinch of salt; cook until translucent, about 4 minutes.
- Add the garlic and the reserved chopped mushroom stems. Sauté until tender and any moisture has evaporated, 4–5 minutes longer.
- Remove from the heat and let cool slightly.
3. Make the Filling
- In a large bowl, combine:
- Mashed potatoes
- Cooked wild rice
- Sautéed onion, garlic, and mushroom stem mixture
- Grated parmesan cheese
- Chopped parsley and any additional fresh herbs
- Sour cream or Greek yogurt
- Salt and pepper to taste
- Optional toasted nuts for texture and flavor
- Stir everything together until well blended. Taste and adjust seasoning as needed.
4. Assemble and Bake
- Spoon the potato-wild rice filling generously into each mushroom cap. Mound the filling slightly for an impressive look.
- Brush the tops lightly with more melted butter. If desired, sprinkle with a little extra parmesan or chopped nuts for a golden, flavorful crust.
- Bake for 20–25 minutes, or until the mushrooms are tender and the tops are lightly golden.
- Let cool for at least 5–10 minutes before serving. This helps the flavors meld and makes the mushrooms easier to eat.
5. Garnish and Serve
- Transfer the mushrooms to a serving platter.
- Sprinkle with more fresh herbs or a touch of paprika for color.
- Serve warm or at room temperature as an appetizer, side, or even a meatless main dish.
Tips for Success
- Use cold or leftover mashed potatoes for the best texture and easiest mixing.
- For extra richness, try swapping in cream cheese for the sour cream or add shredded sharp cheddar to the filling.
- Mushrooms release moisture as they bake. For an extra-crispy underside, pre-bake the caps for 10 minutes before filling.
- Make ahead: Assemble the mushrooms up to 1 day in advance, cover, and refrigerate. Bake just before serving.
