Mushroom Melts

This mushroom melt has both Gruyère and Swiss cheeses that work together with earthy mushrooms to create a delicious ooey-gooey vegetarian grilled cheese. Balsamic vinegar helps lighten the sandwich, and the thin slices of rye bread help keep the sodium in check.

  • 2 tablespoons extra-virgin olive oil

  • 2 tablespoons chopped shallot

  • 1 (8-ounce) package cremini mushrooms, thinly sliced

  • 1 teaspoon chopped fresh thyme

  • 2 tablespoons balsamic vinegar

  • 8 thin slices rye bread (about 1 ounce each)

  • 2 tablespoons unsalted butter, softened

  • 4 (1-ounce) slices Swiss cheese

  • ½ cup shredded Gruyère cheese


  1. Preheat oven to 200°F. Heat oil in a large nonstick skillet over medium-high heat. Add shallot and cook, stirring often, until softened, about 3 minutes. Add mushrooms and thyme; cook, stirring occasionally, until the mushrooms soften and begin to brown, about 10 minutes. Add vinegar; cook, stirring often, until mostly evaporated, about 2 minutes. Transfer the mushroom mixture to a bowl and set aside.

  2. Coat 1 side of each bread slice evenly with butter and set 4 slices aside. Place the remaining 4 slices, coated-sides down, on a cutting board. Top each with 1 slice Swiss cheese, 2 ½ tablespoons mushroom mixture and 2 tablespoons Gruyère. Top with the remaining bread slices, coated-sides up.

  3. Wipe the skillet clean and heat over medium heat. Add 2 sandwiches; cook until the bottom side is crispy and browned, 2 to 3 minutes. Carefully turn the sandwiches over and continue cooking until the cheese has completely melted, about 2 minutes more. (Alternatively, heat a panini press to medium. Place 2 sandwiches on the cooking grates and close the press. Cook until both sides of the sandwiches are browned and crisp and the cheese is melted, about 2 minutes.) Remove from the skillet; keep warm in the oven. Repeat with the remaining sandwiches.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. 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. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
