These Mushroom & Spinach Melts Are So Good, You'll Cry

These mushroom-and-spinach melts check all the boxes: they're cheesy, packed with veggies and easy to make—what's not to love? Balsamic vinegar adds a wonderful sharpness to cut through the cheese, and pairs well with the sautéed vegetables. You can also make these sandwiches with a panini press, if you have one. Heat the press to medium and place 2 sandwiches on the cooking grates; cook until both sides are browned, crisp and the cheese is melted, about 2 minutes. Repeat with the remaining sandwiches.

  • 2 tablespoons extra-virgin olive oil

  • 2 tablespoons thinly sliced shallot

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

  • 1 teaspoon chopped fresh thyme

  • 1 (5 ounce) package baby spinach

  • 2 tablespoons balsamic vinegar

  • 8 (1/2-inch) slices whole-grain bread

  • 2 tablespoons unsalted butter, softened

  • 4 slices provolone cheese

  • ½ cup shredded fontina cheese


  1. Preheat oven to 200°F. Heat oil in a large nonstick skillet over medium-high heat. Add shallot; cook, stirring often, until softened, about 3 minutes. Add mushrooms and thyme; cook, stirring occasionally, until the mushrooms soften and turn golden brown, 8 to 10 minutes. Add spinach and vinegar; cook, stirring constantly, until the spinach is wilted and the vinegar is mostly evaporated, about 2 minutes. Transfer the mixture to a medium bowl.

  2. Coat 1 side of each bread slice evenly with a thin layer of butter. Flip 4 slices butter-sides down; top each with 1 slice provolone, 1/3 cup mushroom-spinach mixture and 2 tablespoons fontina. Top with the remaining bread slices, butter-sides up.

  3. Wipe the pan clean and place over medium heat. Add 2 sandwiches; cook until crispy and browned on the bottom, 2 to 3 minutes. Carefully turn the sandwiches over and continue cooking until the cheese has completely melted, about 2 minutes. Transfer the sandwiches to a small baking sheet; 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.)
