1 tablespoon olive oil
2 pounds Italian sausage, casings removed
2 (24 ounce) jars tomato sauce
2 cups water
1 pound whole-milk ricotta cheese
2 tablespoons fresh flat-leaf parsley, chopped
kosher salt, to taste
freshly ground pepper, to taste
18 ruffle-edged lasagna noodles, not no-boil
1 1/2 pound mozzarella cheese, grated and divided
2 ounces Parmigiano-Reggiano cheese, finely grated and divided
fresh basil, optional, thinly sliced, for garnish


Step 1

In a skillet on the stovetop, heat the olive oil over medium heat.

Step 2

Add the sausage to the skillet and cook, breaking up meat into smaller chunks with a spoon, until the meat is browned, about 10-12 minutes.

Step 3

Add the tomato sauce and water to the skillet and bring the mixture to a simmer.

Step 4

Turn off the heat and set the mixture aside.

Step 5

In a bowl, combine the ricotta cheese, parsley, salt, and pepper. Set aside.

Step 6

In the insert to a slow-cooker, spread a thin layer of the meat sauce on the bottom.

Step 7

Cover the sauce with a single layer of uncooked lasagna noodles, breaking the noodles as needed to fit, about 3 noodles per layer.

Step 8

Spread 1/3 cup of the ricotta cheese mixture over the noodle layer.

Step 9

Spread 2 cups of the meat and sauce mixture over the ricotta cheese layer.

Step 10

Sprinkle 1 cup of the mozzarella and 1/4 cup of Parmigiano-Reggiano over the meat and sauce mixture.

Step 11

Repeat the layering 4 more times, starting with the noodles.

Step 12

Place the slow-cooker insert into the base and cover with the lid.

Step 13

Cook on low until the noodles are tender and cooked through, about 4 hours.

Step 14

Preheat the oven to broil and carefully transfer the slow-cooker insert into the oven.

Step 15

Broil until the cheese is bubbly and golden brown, about 3 minutes.

Step 16

Let the lasagna rest for about 20 minutes before serving.

Step 17

Garnish with basil and serve.
