Tips & Variations
- For a richer flavor, try using full-fat feta cheese or sprinkle some Parmesan on top before baking.
- You can substitute fresh spinach for frozen if you have it; just be sure to cook and drain it well.
- Add a pinch of red pepper flakes to the filling for a subtle spicy kick.
- Use white button mushrooms if creminis are not available; they work just as well.
Storage
Store leftover stuffed mushrooms in an airtight container in the refrigerator for up to 3 days. To reheat, warm them gently in a preheated oven at 350° F for about 10 minutes until heated through. Avoid microwaving to keep the texture intact.

FAQs
Can I prepare these mushrooms ahead of time?
Yes, you can prepare the filling and stuff the mushrooms up to a day in advance. Keep them covered in the refrigerator and bake just before serving for best results.
What if I don’t have sundried tomatoes?
If you don’t have sundried tomatoes, you can substitute with roasted red peppers or skip them altogether; the filling will still be flavorful thanks to the garlic, feta, and spinach.

Ingredients
Mushrooms
- 1 lb Cremini Mushrooms (AKA Baby Bellas), cleaned
- 2 tsp Olive Oil
Filling
- ½ medium Onion (minced)
- ¼ cup Sundried Tomatoes in oil (minced)
- 2 garlic cloves (minced)
- 8 oz Frozen Spinach (thawed, excess liquid squeezed out)
- ¼ cup Chopped Parsley
- ¼ cup Fat Free Feta Cheese
- Freshly Ground Black Pepper to taste
Instructions
- Preheat Oven: Preheat your oven to 400°F (200°C) to ensure it’s hot and ready for baking the stuffed mushrooms.
- Prepare Baking Sheet: Line a baking sheet with parchment paper to prevent sticking and facilitate easy cleanup.
- Prepare Mushroom Caps: Gently remove the stems from the mushroom caps and place the caps upside down on the prepared baking sheet.
- Chop Stems: Finely chop the mushroom stems to use in the filling mixture.
- Sauté Aromatics: Heat the olive oil in a large skillet over medium heat. Add the chopped mushroom stems, minced onion, sundried tomatoes, and garlic cloves. Sauté until the onions turn translucent, releasing their sweetness and softening the mixture.
- Combine Filling: Remove the skillet from heat. Add the thawed and drained spinach, chopped parsley, fat-free feta cheese, and freshly ground black pepper. Stir everything together until well combined and the filling is evenly mixed.
- Stuff Mushrooms: Carefully spoon the filling into each mushroom cap, packing it down slightly to ensure it stays in place during baking.
- Bake: Place the baking sheet in the oven and bake for 20 to 30 minutes, or until the mushrooms are cooked through, golden brown on top, and not releasing excess liquid.
- Serve: Remove from oven and serve immediately while warm for the best flavor and texture.
Notes
- Make sure to squeeze out as much liquid as possible from the thawed spinach to avoid soggy stuffing.
- You can substitute fresh spinach if preferred; just sauté it lightly before use.
- Using fat-free feta keeps this dish lower in fat, but regular feta can be used for a richer flavor.
- Feel free to add a pinch of red pepper flakes for a subtle heat boost.
- These stuffed mushrooms pair well with a crisp salad or as an elegant appetizer at gatherings.
