Bring a large pot of salted water to a boil. Cook the pasta according to the package directions. When it’s done, reserve 1 cup of pasta water then drain. Do not rinse the pasta.
12 ounces penne pasta
While the pasta is cooking, make the pasta sauce. Heat the olive oil in a large pan over medium-high heat. Once it’s hot and shimmering, add the chicken sausage and cook, stirring frequently, for 4-5 minutes, or until it’s heated through and browned on each side. Transfer it to a clean plate or cutting board.
1 Tablespoon olive oil, 12 ounces (4 links) Italian chicken sausage
Add the butter to the same skillet over medium heat and stir to melt. Add the onion and cook for 2-3 minutes, until translucent. Add the garlic, Italian seasoning, and red pepper flakes and cook and soften until the garlic is fragrant, 1-2 minutes.
1 Tablespoon unsalted butter, 1 small yellow onion, 3 cloves garlic, 2 teaspoons Italian seasoning, Pinch of red pepper flakes
Stir in the tomato paste, marinara, and cream and stir until smooth. Add the broccoli florets and stir to coat it in the sauce. Simmer the sauce and broccoli for 5 minutes or until it reduces and thickens to your liking. Adjust the heat if it’s starting to boil beyond a gentle bubble around the edges.
3 Tablespoons tomato paste, 24 ounces Marinara sauce, 1 cup heavy cream, 3 cups broccoli florets
Season with salt and pepper to taste. Stir in the pasta and cooked sausage until combined and the sauce is coating the pasta. Add a splash of the reserved pasta water if the sauce gets too thick. Serve with parmesan cheese and fresh herbs.
1/2 teaspoon kosher salt
