With a little help from frozen ravioli, you can pull a skillet of toasty, bubbly lasagna from the oven in a little more than half an hour. In this ingenious one pan supper, you make a tomato sauce right in the same skillet you use to bake the whole thing, and the ravioli—layered with mozzarella and Parm—cooks and soaks up the tomato flavor at the same time the starch from the pasta thickens the sauce.

　　

Ingredients

Tomato Sauce:

2 tbsp. extra-virgin olive oil

　　2 large garlic cloves, thinly sliced

　　2 tbsp. tomato paste

　　Pinch of dried red pepper flakes

　　1 (28-oz.) can crushed tomatoes

　　2 large fresh basil sprigs, plus torn leaves for garnish

　　1 tsp. sugar

　　1 tsp. coarse kosher salt (preferably Diamond Crystal)

　　¼ tsp. freshly ground black pepper

　　

Lasagna:

1½ lbs. frozen cheese ravioli

　　8 oz. mozzarella cheese (preferably fresh), shredded (2 cups)

　　Parmesan cheese

　　

Make the tomato sauce:

Step 1

Preheat the oven to 450°F with a rack in the center. Heat the oil in a large ovenproof skillet over medium heat until shimmering, about 2 minutes. Add the garlic and cook, stirring, until softened but not browned, 1 to 2 minutes. Add the tomato paste and cook, stirring, until it darkens slightly, 1 to 2 minutes. Add the red pepper flakes, crushed tomatoes, basil sprigs, sugar, and 1 cup water. Season with the salt and black pepper and increase the heat slightly to bring to a boil.

　　

Cook the ravioli:

Step 2

Gently separate any frozen ravioli stuck together without tearing. Any that resist will separate during cooking. Add the ravioli to the skillet and cook over medium heat, stirring gently, until the sauce is very thick and the ravioli are just tender, about 15 minutes.

　　

Assemble the ravioli lasagna:

Step 3

Spoon half of the ravioli and sauce into a bowl. Arrange the ravioli in the skillet in an even layer and sprinkle with half of the mozzarella. Arrange the remaining ravioli on top and sprinkle with the Parmesan and remaining mozzarella.

　　

Bake the ravioli lasagna:

Step 4

Bake until bubbling and the cheese is lightly browned, 10 to 12 minutes. Scatter the basil leaves on top and let rest for 10 minutes before serving.
