How to Make Chicken Parmesan Stuffed Portobello Mushrooms
This dish brings classic Chicken Parmesan flavors into a cozy, low-carb mushroom dish. Here’s how it all comes together:
• Portobello mushrooms roasted until just tender
• A mixture of ground chicken, Parmesan, spinach, parsley, garlic, onion, and seasonings
• Filling pressed onto the mushrooms and baked until fully cooked
• Topped with shredded Italian cheese or mozzarella
• Finished with warm marinara sauce and extra Parmesan or parsley
• Each mushroom becomes a complete, flavorful, and filling meal
It is an easy, healthy dinner that is packed with flavor and very little cleanup.
Ingredients
• 6 large portobello mushroom caps, cleaned and stems removed
• ½ cup grated Parmesan cheese (plus extra for garnish)
• ⅓ cup fresh parsley, finely chopped (plus extra for garnish)
• 1 medium onion, very finely chopped
• 1 egg
• 6 garlic cloves, minced
• ½ teaspoon onion powder
• 1 teaspoon salt
• 1 teaspoon black pepper
• 10 ounces frozen spinach, thawed and all liquid squeezed out
• 1 pound ground chicken, 93% lean
• 2 cups marinara sauce
• 4 ounces shredded Italian cheese blend or shredded mozzarella
Directions
- Prepare the Mushrooms:
- Preheat the oven to 450°F and line a baking sheet with parchment paper.
- Place the mushrooms top-side up and roast for 10 minutes.
- Flip mushrooms, sprinkle with a little salt and pepper, and roast another 5 minutes (or 13 minutes on the first side for very large mushrooms).
- Remove mushrooms, drain any liquid from the pan, and reduce oven temperature to 425°F.
- Make the Filling:
- In a large bowl, combine Parmesan, parsley, onion, egg, garlic, onion powder, salt, and pepper.
- Chop the thawed spinach, sprinkle it over the mixture, and stir to combine.
- Add the ground chicken and mix until evenly combined.
- Stuff the Mushrooms:
- Turn mushrooms top-side down on the baking sheet.
- Form 6 even balls of the chicken mixture and place one on each mushroom.
- Press down slightly to flatten the tops and spray lightly with cooking spray.
- Bake the Stuffed Mushrooms:
- Bake for 15 to 20 minutes until the chicken is cooked through.
- Sprinkle the shredded Italian cheese on top and bake until the cheese melts and the chicken reaches 165°F.
- Heat the Marinara:
- While mushrooms bake, warm the marinara sauce on the stovetop.
- Serve:
- Remove mushrooms from the oven, top each with marinara sauce, extra Parmesan, and parsley if desired.
- Serve warm.
Process Details
• Roasting the Mushrooms: Roasting softens the mushrooms so they hold the filling without releasing too much water.
• Mixing the Filling: Combining Parmesan, spinach, and seasonings with the chicken creates a moist, flavorful filling.
• Flattening the Filling: Pressing the filling helps it cook evenly and stay on the mushroom.
• Cheese Topping: Adding cheese near the end ensures it melts perfectly without burning.
• Marinara Finish: Warm sauce adds moisture, flavor, and a classic Chicken Parmesan touch.
Tips for Success
• Choose large mushrooms for easier stuffing.
• Make sure to squeeze all liquid from the spinach to avoid a watery filling.
• Use a meat thermometer to ensure chicken reaches 165°F.
• You can use shredded zucchini or chopped broccoli if you prefer no spinach.
• Preheat the oven properly for even cooking of mushrooms and filling.
Serving Ideas
• Family Dinner: Serve one mushroom per person with a simple side salad.
• Meal Prep: Make extra mushrooms and store for lunches or dinners later.
• Low-Carb Plate: Pair with roasted vegetables or cauliflower rice.
• Extra Flavor: Sprinkle with additional Parmesan or fresh herbs before serving.
• Party Appetizer: Use smaller mushrooms for bite-sized portions.
Storage & Freezing
• Refrigerator: Store cooled mushrooms in an airtight container for up to 3–4 days.
• Reheating: Warm in the oven or microwave, adding a splash of marinara if needed.
• Freezing: Cooked filling can be frozen separately for up to 1 month, then reheated before stuffing mushrooms.
• Texture Note: Mushrooms may soften further after storage, but flavors remain delicious.
