Ingredients
For the Roasted Vegetables:- 1 medium head of cauliflower, cut into bite-sized florets
- 1 red bell pepper, cut into 1-inch squares
- 1 medium yellow onion, sliced into wedges (about ½ inch wide)
- 2 tablespoons extra-virgin olive oil, divided
- ¼ teaspoon fine sea salt, divided
- 8 ounces ziti, rigatoni, or penne pasta
- 4 cups (32 ounces) marinara sauce (homemade or store-bought), divided
- ¼ cup fresh basil, chopped (plus extra for garnish)
- 8 ounces (2 packed cups) grated part-skim mozzarella cheese, divided
- 2 cups (16 ounces) cottage cheese or ricotta cheese, divided
Instructions
- Roast the Vegetables:
- Preheat your oven to 425°F, placing racks in the middle and upper thirds of the oven. Line two large, rimmed baking sheets with parchment paper.
- Spread the cauliflower florets on one baking sheet, and the bell peppers and onion on the other.
- Drizzle each pan with half of the olive oil and sprinkle with the sea salt. Toss gently to coat the vegetables evenly.
- Arrange the vegetables in a single layer on each pan. Roast for 30-35 minutes, flipping and swapping the pans’ positions halfway through, until the vegetables are tender and caramelized. Set them aside when done, keeping the oven at 425°F for baking the ziti.
- Cook the Pasta:
- Bring a large pot of salted water to a boil. Cook the pasta according to package directions, but be sure to leave it slightly firm since it will continue cooking while baking. Drain and return to the pot.
- Stir in 2 cups of marinara sauce, the chopped basil, and ½ cup of mozzarella. Mix gently.
- Assemble the Baked Ziti:
- Spread 1 cup of marinara sauce evenly across the bottom of a 9x13-inch baking dish.
- Layer half of the pasta mixture on top, spreading it into an even layer.
- Add the roasted cauliflower evenly over the pasta, then dollop 1 cup of cottage cheese over it (no need to smooth it out). Sprinkle ½ cup of mozzarella over the top.
- Add the second half of the pasta mixture, then top with the roasted peppers and onion. Dollop the remaining cup of cottage cheese on top, followed by another cup of marinara sauce, and finish with the remaining mozzarella cheese.
- Bake the Ziti:
- Place a rimmed baking sheet on the lower oven rack to catch any drips. Set the ziti on the upper rack.
- Bake uncovered for 30 minutes, then move the dish to the top rack for an additional 2-5 minutes, or until the cheese turns a rich golden color.
- Remove from the oven and let it cool for 10 minutes before slicing.
- Serve:
- Garnish with freshly torn basil, slice, and serve.
Notes:
- Gluten-Free Option: Use gluten-free pasta (such as corn and quinoa blend).
- Make Ahead: You can roast the vegetables up to 3 days ahead of time. The dish can also be assembled and refrigerated until you're ready to bake.
- Freezing: The assembled ziti can be frozen before baking.
- Vegan Option: Substitute with a vegan sour cream or similar product for the cottage cheese and omit the mozzarella for a dairy-free version.
