Creamy Butternut Squash Lasagna, with a white Béchamel sauce, is a delicious fall dinner as well as a perfect vegetarian Thanksgiving main dish.
Who are you inviting over for Thanksgiving this year? I always like to invite a mix of both family and friends. Why? Well, first of all, the more the merrier. Especially during the holidays, right? Second, the dynamic between your guests completely changes when you combine both sets of in-laws with friends of yours whom they never met. Ever tried my little trick? If yes, you might know what happens – everyone is on their best behavior. Maybe its just my family, but when I only have my family and my husband’s family over, people mostly stick to only talking to their own blood relatives. When I introduce friends and co-workers into the mix, everyone seems to co-mingle a little bit better.
All of my friends and family have been meat eaters. Of all the years I’ve hosted Thanksgiving, I’ve never had to worry about what I would do if a vegetarian came over for dinner. Well, this year, one of my friends coming over just so happens to be a vegetarian. I know she wouldn’t want me to go out of my way to make something special for her, which is why I especially love this lasagna – it is so delicious that vegetarians and meat eaters alike will love it!
When I think of lasagna, I can’t help but think of red sauce and meat. This is neither. It is made with lasagna noodles and that’s basically the only similarity to traditional lasagna, other than the fact that the ingredients are layered. It incorporates super soft and creamy roasted butternut squash with onions and garlic. Then, since I’m using no-bake lasagna noodles, I must use some kind of liquid to properly cook them. This meal, in addition to a few good handfuls of freshly grated mozzarella and parmasan, uses a Béchamel sauce, also known as white sauce, which is made from a white roux and milk. Even though it first appeared in Italian cooking books, it is now considered one of the mother sauces of French cuisine.
Let me tell you, this dinner tastes like heaven and you will find that it is the best main dish to serve to your vegetarian friends and family at Thanksgiving!
Butternut Squash Lasagna
Print Pin RateIngredients
For the vegetables
- 1 small butternut squash peeled and cut into 1/2-inch cubes (about 5 cups)
- 2 tablespoons extra-virgin olive oil
- Kosher salt
- 1 onion halved and sliced
- 4 cloves garlic sliced
For the bechamel
- 4 tablespoons unsalted butter
- 6 sage leaves sliced into thin ribbons
- 12 basil leaves sliced into thin ribbons
- 4 tablespoons all-purpose flour
- 4 cups whole milk
- Pinch of freshly grated nutmeg
For the lasagna
- Unsalted butter for greasing the baking dish
- 2 cup low-moisture mozzarella cheese grated (about 8 ounces)
- 1 cup parmesan cheese grated (about 4 ounces)
- 9 no-boil lasagna noodles
Instructions
- Make the vegetables: Preheat the oven to 425 degrees F. Toss the squash with 1 tablespoon olive oil on a baking sheet; season with salt. Toss the onion with the remaining 1 tablespoon olive oil on a separate baking sheet; season with salt. Roast, rotating the baking sheets once, until the vegetables are tender, 18 to 20 minutes; set aside. Reduce the oven temperature to 350 degrees F.
- Meanwhile, make the bechamel: Melt the butter in a medium saucepan over medium heat. Add the sage and basil and cook 1 minute. Whisk in the flour until smooth; cook, whisking, until the flour is lightly golden but not brown, about 2 minutes. Gradually whisk in the milk until smooth. Bring to a boil, then reduce the heat to medium low and simmer, stirring occasionally, until thickened, about 5 minutes. Stir in the nutmeg.
- Assemble the lasagna: Butter a 9-by-13-inch baking dish. Toss the cheeses and the flour in a bowl; set aside 1/2 cup for topping. Evenly coat the bottom of the dish with 1/2 cup of the bechamel. Lay 3 noodles side by side on top. Cover with one-third of the remaining bechamel. Sprinkle with half of the remaining cheese mixture, then top with half of the vegetable mixture. Arrange 3 more noodles on top and repeat the layers (bechamel, cheese, vegetables). Top with the remaining 3 noodles, then cover with the remaining bechamel; sprinkle with the reserved 1/2 cup cheese.
- Loosely cover the dish with foil and bake until bubbly, about 45 minutes. Turn on the broiler. Uncover the lasagna and broil until browned, about 2 minutes. Let stand 15 minutes before serving.
When do you add basil?
Oh and can you use homemade noodles instead f no boil?
Only if you send me some! Homemade is always best!
Sorry about that! You add it when you add the sage. I updated the instructions. Thanks!
The Lasagna was delicious! I added my Parmesan cheese to the bechemal sauce. Thank you for the recipe!
Krissy,
In the recipe ingredients it states 6 lasagna noodles. In the instructions, it states that you layer 3 noodles 3 separate times. So that would be 9 lasagna noodles. Right?
Doh! Sorry about that! Yes – 9 noodles total. I just updated the recipe. Thank you so much for catching that!
