Nutritional Info

Ingredients

  • 4

    large (4-inch wide) portobello mushrooms

  • 3 tablespoons

    olive oil, divided

  • 1/2 teaspoon

    kosher salt, divided

  • 1/2 teaspoon

    freshly ground black pepper, divided

  • 1

    small yellow onion

  • 1/2

    large lemon

  • 2 ounces

    whole-milk low-moisture mozzarella cheese, shredded (about 1/2 cup)

  • 1/2 ounce

    Parmesan cheese, grated (about 2 tablespoons)

  • 2 tablespoons

    panko bread crumbs

  • 1

    (10.5-ounce) can Campbell’s® Condensed Cream of Mushroom Soup

  • 1

    (5-ounce) bag baby spinach (about 5 cups)

Instructions

  1. Arrange a rack in the top third of the oven and heat the oven to 400°F.

  2. Gently wipe 4 large portobello mushrooms with a paper towel or clean kitchen towel to remove any dirt. Remove the stems by holding the cap in your hand and gently wiggling the stem back and forth until it releases. Reserve the stems. Use a spoon to gently scrape out and discard the mushroom gills to make room for the stuffing.

  3. Brush the mushroom caps with 1 tablespoon of the olive oil, then season with 1/4 teaspoon of the kosher salt and 1/4 teaspoon of the black pepper. Arrange the mushroom caps stem-side up on a rimmed baking sheet.

  4. Coarsely chop the mushroom stems (about 1/2 cup). Finely chop 1 small yellow onion (about 1 cup). Juice 1/2 large lemon until you have 1 tablespoon juice. Shred 2 ounces mozzarella cheese (about 1/2 cup) and grate 1/2 ounce Parmesan cheese (about 2 tablespoons). Combine the Parmesan cheese and 2 tablespoons panko bread crumbs in a small bowl and set aside.

  5. Heat the remaining 2 tablespoons olive oil in a large skillet over medium-high heat until shimmering. Add the mushrooms and onion, the remaining 1/4 teaspoon kosher salt, and the remaining 1/4 teaspoon black pepper, and cook until tender, 5 to 6 minutes.

  6. Add 1 can Campbell’s® Condensed Cream of Mushroom Soup and the mozzarella cheese, and stir to combine. Add 6 ounces baby spinach and the lemon juice, and stir until just wilted, about 3 minutes.

  7. Divide the filling between the mushroom caps (about 1/2 cup per mushroom). Top each mushroom evenly with the cheese and breadcrumb mixture. Roast until the mushrooms are tender, the filling is hot, and the tops are golden brown, about 10 to 12 minutes. If the topping is not sufficiently browned, switch the broiler on and broil until the cheese browns, 2 to 3 minutes.
