While most of the ingredients in this recipe are common pantry staples, you may need to pick up fresh portobello mushrooms and spinach if you don't already have them on hand. Portobello mushrooms are large, meaty mushrooms that can be found in the produce section of most supermarkets. Fresh spinach is also typically available in the produce section, either in bunches or pre-washed bags.
Ingredients For Spinach Stuffed Portobello Mushrooms
Portobello mushrooms: Large, meaty mushrooms that serve as the base for the stuffing.
Spinach: Fresh, leafy greens that add a nutritious and flavorful component to the stuffing.
Onion: Adds a sweet and savory flavor to the stuffing.
Garlic: Provides a pungent, aromatic element to the dish.
Breadcrumbs: Helps bind the stuffing together and adds a slight crunch.
Parmesan cheese: Adds a rich, salty flavor to the stuffing.
Olive oil: Used to sauté the vegetables and add moisture to the stuffing.
Salt: Enhances the overall flavor of the dish.
Pepper: Adds a hint of spice and depth to the stuffing.
Technique Tip for This Recipe
When preparing the portobello mushrooms, make sure to remove the stems carefully to create a deeper cavity for the filling. This will allow you to pack more of the spinach mixture into each mushroom cap, enhancing the flavor and texture of the dish. Additionally, brushing the mushrooms lightly with olive oil before stuffing can help them roast more evenly and develop a richer taste.
Suggested Side Dishes
Alternative Ingredients
portobello mushrooms - Substitute with large cremini mushrooms: Large cremini mushrooms have a similar texture and flavor profile to portobello mushrooms, making them a suitable alternative.
chopped fresh spinach - Substitute with kale: Kale can provide a similar leafy green texture and is also nutrient-dense, though it may need to be cooked slightly longer to soften.
finely chopped onion - Substitute with shallots: Shallots offer a milder, sweeter flavor compared to onions and can add a subtle depth to the stuffing.
minced garlic - Substitute with garlic powder: If fresh garlic is unavailable, garlic powder can be used to impart a similar garlicky flavor. Use about ¼ teaspoon of garlic powder per clove of garlic.
breadcrumbs - Substitute with panko: Panko breadcrumbs provide a lighter, crispier texture compared to regular breadcrumbs, which can enhance the stuffing's texture.
grated parmesan cheese - Substitute with grated pecorino romano: Pecorino Romano has a similar salty, umami flavor but is slightly sharper, which can add an extra kick to the dish.
olive oil - Substitute with avocado oil: Avocado oil has a high smoke point and a neutral flavor, making it a good alternative for cooking and sautéing.
salt - Substitute with soy sauce: Soy sauce can add a similar salty flavor along with a bit of umami, enhancing the overall taste of the stuffing.
pepper - Substitute with white pepper: White pepper has a slightly different flavor profile but can still provide the necessary heat and spice to the dish.

How to Store / Freeze This Dish
- Allow the spinach stuffed portobello mushrooms to cool completely after baking. This prevents condensation and sogginess when stored.
- Place the cooled mushrooms in an airtight container. If stacking, separate layers with parchment paper to avoid sticking.
- Store the container in the refrigerator for up to 3 days. For best results, consume within this timeframe to enjoy the freshest flavors.
- To freeze, individually wrap each stuffed mushroom in plastic wrap or aluminum foil. This helps maintain their shape and prevents freezer burn.
- Place the wrapped mushrooms in a freezer-safe bag or container. Label with the date to keep track of storage time.
- Freeze for up to 2 months. Beyond this period, the texture and taste may degrade.
- When ready to reheat, thaw the mushrooms in the refrigerator overnight. This gradual thawing preserves the texture of the portobello mushrooms.
- Preheat your oven to 350°F (175°C). Place the thawed mushrooms on a baking sheet and cover loosely with foil to prevent drying out.
- Bake for 15-20 minutes, or until heated through. For a crispier topping, remove the foil during the last 5 minutes of baking.

How to Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the leftover spinach stuffed portobello mushrooms on a baking sheet. Cover them loosely with aluminum foil to prevent drying out. Heat for about 15-20 minutes, or until the mushrooms are warmed through and the filling is hot.
Microwave Method: Place the stuffed mushrooms on a microwave-safe plate. Cover with a microwave-safe lid or another plate to retain moisture. Heat on medium power for 1-2 minutes, checking halfway through. Continue heating in 30-second intervals until thoroughly warmed.
Stovetop Method: Heat a non-stick skillet over medium heat. Add a small amount of olive oil or butter to the pan. Place the stuffed mushrooms in the skillet, cover with a lid, and heat for about 5-7 minutes, turning occasionally, until the mushrooms and filling are heated through.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the stuffed mushrooms in the air fryer basket in a single layer. Heat for about 5-7 minutes, checking halfway through, until the mushrooms are warmed and the filling is hot.
