This hearty baked-pasta dish includes cipollini onions, an Italian variety that is slightly larger than a boiling onion. (Cipollina means small onion in Italian.) These disk-shaped onions have a sweet, mild flavor and are ideal for roasting and braising.

- 1 1/2 pound Italian Sausage, halved and cut into 1/2-inch-thick slices
- 2 bunches broccoli rabe or broccolini, cut into 1-inch pieces
- 1/2 cup dry white wine
- Salt and freshly ground pepper, to taste
- 24 garlic cloves, peeled and simmered in 1/3 cup olive oil until tender, oil reserved
- 8 ounces cipollini onions, peeled and halved
- 3 fresh thyme springs
- 1/2 pound rigatoni, cooked until al dente
- 1 cup ricotta cheese
- Pinch of red chili flakes
- 2 ounces Parmigiano-Reggiano cheese, grated
- 1 Preheat an oven to 400°F.
- 2 In a sauté pan over medium heat, brown the sausage for 2 to 3 minutes. Using a slotted spoon, transfer to a large bowl.
- 3 Add the broccoli rabe to the pan and cook until tender, 6 to 8 minutes, adding the wine after 3 minutes. Season with salt, then add the broccoli rabe and cooking liquid to the bowl with the sausage.
- 4 In the same pan over medium heat, warm the reserved garlic oil. Add the onions and thyme, and season with salt and pepper. Cook, stirring occasionally, until the onions are very soft and caramelized, about 15 minutes.
- 5 Using a slotted spoon, transfer to the bowl with the sausage and broccoli rabe; reserve the oil. Add the pasta and garlic to the bowl and season with salt and pepper.
- 6 Spoon half of the pasta mixture into a 3-quart baking dish and dot with half of the ricotta. Top with the remaining pasta and ricotta.
- 7 Drizzle with the reserved oil and sprinkle with the chili flakes. Bake for 20 minutes, then sprinkle with the Parmigiano-Reggiano cheese and bake until hot and golden brown, about 10 minutes more.
