Baked Pasta With Kale - cooking recipe

Ingredients

1 lb penne, whole wheat (or other short pasta)
1 lb kale, stems discarded and leaves cut into 2-inch pieces
3 tablespoons olive oil
20 ounces turkey sausage, Italian, casings removed
1 onion, chopped
kosher salt
pepper
2 garlic cloves, finely chopped
1 tablespoon all-purpose flour
1 cup milk, 1%
1/2 teaspoon crushed red pepper flakes
14 1/2 ounces diced tomatoes, drained
1 cup part-skim ricotta cheese
4 ounces part-skim mozzarella cheese, shredded
2 ounces parmesan cheese, grated

Preparation

Heat oven to 350 degrees F. Cook the pasta according to package directions, adding the kale during the last 3 minutes of cooking. Drain the pasta and kale and return it to the pot.
Meanwhile, heat 1 tablespoon oil in a large nonstick skillet over medium heat. Add the sausage and cook, breaking it up with a spoon, until beginning to brown, 5 to 6 minutes; transfer to a bowl.
Add the onion and remaining 2 tablespoons oil to the skillet, season with 1/2 teaspoon each salt and pepper and cook, covered, stirring occasionally, until tender, 6 to 8 minutes. Stir in the garlic and cook for 1 minute.
Sprinkle the flour over the onion mixture and cook, stirring, for 1 minute. Stirring constantly, gradually add the milk. Simmer, stirring occasionally, until slightly thickened, 2 to 3 minutes; stir in the crushed red pepper.
Add the sauce to the pasta and kale and toss to coat. Add the sausage, tomatoes, ricotta and mozzarella and toss to combine. Transfer the pasta mixture to a 3-quart or 9- by 13-inch casserole dish. Sprinkle with the Parmesan and bake until heated through and golden brown, 20 to 25 minutes.
