Healthy Recipes Ingredient Mushroom Portobello Mushroom Cheese-&-Spinach-Stuffed Portobellos 4.7 (34) 34 Reviews Here we take the elements of a vegetarian lasagna filling--ricotta, spinach and Parmesan cheese--and nestle them into roasted portobello mushroom caps. The recipe works best with very large portobello caps; if you can only find smaller ones, buy one or two extra and divide the filling among all the caps. Serve with a tossed salad and a whole-wheat dinner roll or spaghetti tossed with marinara sauce.

This recipe was developed and tested at its original yield and has not been tested at other yields. Note that only the ingredient list is scaled, so you may need to make adjustments to ingredient amounts, cooking times and equipment sizes in the recipe steps. Scaling could also impact the nutrition analysis. Original recipe (1X) yields 4 servings 4 large portobello mushroom caps ¼ teaspoon salt ¼ teaspoon freshly ground pepper, divided 1 cup part-skim ricotta cheese 1 cup finely chopped fresh spinach ½ cup finely shredded Parmesan cheese, divided 2 tablespoons finely chopped kalamata olives ½ teaspoon Italian seasoning ¾ cup prepared marinara sauce Directions Preheat oven to 450 degrees F. Coat a rimmed baking sheet with cooking spray. Place mushroom caps, gill-side up, on the prepared pan. Sprinkle with salt and 1/8 teaspoon pepper. Roast until tender, 20 to 25 minutes. Meanwhile, mash ricotta, spinach, 1/4 cup Parmesan, olives, Italian seasoning and the remaining 1/8 teaspoon pepper in a medium bowl. Place marinara sauce in a small bowl, cover and microwave on High until hot, 30 seconds to 1 1/2 minutes. When the mushrooms are tender, carefully pour out any liquid accumulated in the caps. Return the caps to the pan gill-side up. Spread 1 tablespoon marinara into each cap; cover the remaining sauce to keep warm. Mound a generous 1/3 cup ricotta filling into each cap and sprinkle with the remaining 1/4 cup Parmesan. Bake until hot, about 10 minutes. Serve with the remaining marinara sauce. Tips Easy cleanup: Recipes that require cooking spray can leave behind a sticky residue that can be hard to clean. To save time and keep your baking sheet looking fresh, line it with a layer of foil before you apply the cooking spray.

Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients.
