Ingredients

4 large portobello mushrooms
3 tablespoons extra-virgin olive oil
1 1/4 teaspoons fine salt
2 teaspoons Italian seasoning
1 medium tomato, sliced into rounds
3 large garlic cloves, minced
2 packed cups baby spinach, coarsely chopped
3 green onions, coarsely chopped
1/2 cup whole milk ricotta cheese
1/4 cup breadcrumbs

Instructions

Get ready: Preheat the oven to 350°F and line a baking sheet with aluminum foil or parchment paper.
Prepare the mushrooms: Gently wash the mushrooms to remove any debris and carefully snap off the stems (save them for later). Use the side of a spoon to scrape out the gills of the mushroom caps, taking care to keep the mushrooms intact.
Oil and season: Use a brush or your hands to coat the outer sides and edges of the mushrooms with about 1 tablespoon of olive oil. Place on the prepared baking sheet with the hollow sides facing up. Sprinkle with about 1/4 teaspoon of salt and 1/2 teaspoon of the Italian seasoning. Place a tomato slice on top of each mushroom cap. Set aside.
Saute the vegetables: Coarsely chop the mushroom stems. In a medium skillet on medium-low heat, add 2 tablespoons of extra-virgin olive oil. Once the oil begins to shimmer, add the garlic and stir constantly for 30 seconds before adding the chopped mushroom stems, spinach, and green onion. Add the remaining 1 teaspoon of salt. Cook until the spinach is wilted, about 5 minutes. Turn off the heat and set aside.
Stuff and bake: In a small mixing bowl, mix together the ricotta cheese and remaining 1 1/2 teaspoons of Italian seasoning. Add the sauteed vegetables and stir to combine. Distribute the mixture evenly among each mushroom. Place in your oven to bake for 15 minutes.
Finish and serve: After the time is up, remove from the oven, top with the breadcrumbs and a drizzle of extra-virgin olive oil. Return to the oven and broil on low until the tops are golden brown, about 3 to 5 minutes. Let cool for 5 minutes before serving.

Notes

Mushrooms are like sponges: If you submerge them in water or even just run water over them, you’ll risk them becoming tough and tasteless. Instead, gently brush off any dirt from the surface with a dry towel. Use a damp towel for more stubborn debris. To remove the stems, gently push against them with your thumb. As for the gills, a scape with a small spoon will do the trick.
If your oven doesn’t have a low broil setting, simply broil on high until the tops are golden brown, about 1 to 2 minutes. Keep a close eye on things to ensure it doesn’t burn.
To cook in an air fryer, reduce the baking time (“stuff and bake” in step six) to about 10 minutes. Then, add the breadcrumbs and return to the fryer to brown for 3 to 5 minutes.
