This butternut squash lasagna recipe combines sweet roasted squash and bechamel sauce with lasagna noodles, parmesan, and fresh herbs. It's the best winter comfort food!
Prep. Preheat oven to 400ºF. Lightly grease a baking sheet and set aside.
Season the squash. Combine chopped squash, olive oil, salt, and pepper in a mixing bowl and toss to coat. Spread the squash in a single layer on the prepared baking sheet.
Roast the squash. Roast the squash in the oven for 40 minutes, stirring once or twice, until soft. Afterward, remove the squash from the oven and reduce the oven temperature to 375ºF.
Make the sauce. In the meantime, heat butter in a large saucepan over medium heat. Add garlic and cook until fragrant, about 20 seconds. Then, whisk in the flour. Slowly add milk and season with salt and pepper. Cook and stir frequently until thickened and bubbly, about 8 to 10 minutes.
Combine. Stir butternut squash, rosemary, and chili powder into the prepared sauce.
Assemble. Butter a 3-quart casserole dish. Spoon 1/2 cup of the sauce on the bottom of the prepared baking dish. Layer on three to four of the no-bake noodles. Top that with 1/3 of the remaining sauce, and sprinkle on 1/3 of the parmesan cheese. Repeat, layering the noodles, sauce, and cheese two more times.
Finish the lasagna. Pour whipping cream over the entire dish and sprinkle the top with the remaining parmesan cheese.
Bake! Cover the dish with foil. Bake for 35 to 40 minutes, or until bubbly. Uncover and continue to bake for 10 more minutes, or until the top is lightly browned. Let stand 15 minutes before cutting and serving.
