Ingredients

Kosher salt
8 ounces lasagna noodles, broken into pieces (about 10 noodles)
1 tablespoon extra-virgin olive oil, plus more for drizzling
1 onion, chopped
1/2 pound hot or sweet Italian sausage, casings removed
3 cloves garlic, chopped
1 teaspoon dried oregano
2 tablespoons tomato paste
4 cups low-sodium chicken broth
1 15-ounce can crushed or diced tomatoes
1/2 cup chopped fresh basil, plus thinly sliced leaves for topping
1/3 cup grated Parmesan cheese (plus more for sprinkling, optional)
1/4 cup heavy cream or half-and-half
Ricotta cheese, for topping

Directions

Bring a large pot of salted water to a boil. Add the noodles and cook as the label directs. Drain; drizzle with olive oil and toss.

Meanwhile, heat 1 tablespoon olive oil in a large Dutch oven or heavy-bottomed pot over medium-high heat. Add the onion and cook, stirring, until softened, about 4 minutes. Add the sausage, garlic and oregano and cook, stirring and breaking up the sausage with a wooden spoon, until the sausage is browned, about 3 minutes. Add the tomato paste and cook, stirring, until darkened, about 2 minutes.

Add the chicken broth, tomatoes and 1 cup water; cover and bring to a simmer. Uncover and cook until slightly reduced, about 10 minutes. Stir in the noodles, basil, Parmesan and heavy cream; simmer 2 more minutes.
Divide the soup among bowls. Top with ricotta and sliced basil.
