One-Skillet Vegetable Lasagna

One-Skillet Vegetable Lasagna


Serves 4 (serving size: about 1 1/2 cups)

The best part of this vegetable lasagna—aside from the flavor—is the low-cleanup: Vegetables take turns cooking in a single cast iron skillet, not several. A stovetop simmer quickly cooks the noodles through, so there's no need for a separate pot to boil them. Then the pan shifts easily to the oven for a last-minute broil to melt and meld the cheeses. Perfection!


  • 2 tablespoons olive oil, divided
  • 12 ounces zucchini, cut lengthwise into 1/4-in.-thick slices, divided
  • 1 1/2 cups thinly sliced yellow onion
  • 1 (8-oz.) pkg. presliced cremini mushrooms
  • 4 cups baby spinach
  • 3 garlic cloves, thinly sliced
  • 1 (28-oz.) can unsalted crushed tomatoes, divided
  • 1/2 teaspoon kosher salt
  • 4 1/2 no-boil lasagna noodles
  • 4 ounces part-skim ricotta cheese (about 1 cup)
