Pasta carbonara, pizza Margherita, and a fresh panzanella salad. I love classic Italian dishes, but sometimes I like to experiment. I had to make a vegetarian dish for a dinner with friends, so I thought it would be a perfect opportunity to take a new look at lasagna, traditionally interweaving layers of pasta, ricotta, ragù, béchamel, and Parmigiano-Reggiano.
But let’s take a step back. Many of you might be remembering that dire lasagna from church potlucks – soggy pasta and waterlogged ground beef. I recall separating the pasta and pulling out clumps of tacky ricotta, while trying to remove the cracked fluted edges of noodle from the top layer. Please, try not to associate frozen lasagna with a freshly made version – it’s not even comparable.
The key to this lasagna is the pasta, which lends a wonderful texture and coarseness to the dish. Its chewy, dense consistency reminds me of traditional Italian pastas, perfectly al dente with a slight bite. What I love about this dish is it’s combination textures from creamy ricotta, silky butternut squash, and an earthiness from the crimini mushrooms. The luscious combination of ingredients can stand up to one another, and among all the flavors I can still pick out subtle hints of nutty parmesan.
This recipe is inspired by one I found in an old copy of Bon Appétit.
Ingredients
- 1/4 cup salted butter
- 2 large onions, chopped
- 5 cloves garlic, minced
- 1/2 pound crimini (baby bella) mushrooms, diced (about 3 cups)
- 2 pounds butternut squash, peeled, seeded, cut into 1/4-inch-thick slices (about 5 1/2 cups)
- 1 14-ounce carton vegetable broth
- 4 tablespoons fresh thyme, chopped and divided
- 4 tablespoons fresh sage, sliced and divided
- 3 15-ounce containers whole-milk ricotta cheese
- 4 cups mozzarella cheese, grated and divided
- 2 cups Parmigiano-Reggiano, grated and divided
- 4 spring onions, finely chopped
- 4 large eggs
- Olive oil
- Salt
- Fresh ground pepper
- 2 9-ounce package lasagna noodles. (My favorite brand is Rustichella d’Abruzzo Lasagne all’uovo These noodles need to be boiled before being layered into your lasagna. The original recipe calls for no cook noodles if you want to take out a step)
Method
- Melt butter into a large skillet over medium-high heat. I recommend using a skillet with high sides so you can use one pan for all your steps – heads up you’ll need to simmer your squash and noodles in vegetable broth so pick a larger pan than you might think.
- Add onions and sauté until soft, about 8 minutes and season with salt and pepper.
- Add garlic and sauté for another 1-2 minutes.
- Increase heat to high; add mushrooms and cook until tender, stirring constantly, about 5 minutes. Season with salt and pepper and then transfer the mushroom mixture to a bowl and set aside until you’re ready to assemble the pasta.
- In the same skillet, add squash, broth, 3 tablespoons thyme, and 3 tablespoons sage. Cover and simmer over medium heat until squash is just tender, about 6 minutes. Uncover and cook until squash is very soft but still retains shape, about 5 minutes. Season with salt and pepper.
- Skim the squash from the skillet and set aside. Don’t worry if it starts to fall apart a little, and discard the thyme and sage. Keep any vegetable broth left over in the pan.
- Add 4 cups of water to the broth and bring to a low boil for your pasta sheets.
- While your broth comes to a boil, mix ricotta, 2 cups mozzarella cheese, 1 1/2 cups Parmesan cheese, spring onion, and remaining 1 tablespoon thyme and 1 tablespoon sage in large bowl.
- Mix in eggs and season to taste with salt and pepper.
- Once your broth is at a low boil, place pasta in broth and let simmer for 3 min. Once slightly softened, you can turn off the heat and begin to assemble your lasagna.
- Brush 13x9x2-inch glass or ceramic baking dish with oil. Spread 1 cup ricotta mixture over bottom. Arrange 3 – 4 noodles on top (I usually cut a few so I can cover the entire dish). Spread 13/4 cups ricotta mixture over noodles. Arrange 1 1/3 cups squash mixture over. Sprinkle with 1/2 cup mushrooms and 1 cup mozzarella. Top with 3 noodles, then 1 3/4 cups ricotta mixture, half of remaining squash, 1/2 cup mushrooms, and remaining 1 cup mozzarella. Repeat with noodles, 1 3/4 cups ricotta mixture, remaining squash, and remaining mushrooms. Top with 3 noodles. Spread remaining ricotta mixture over; sprinkle with remaining Parmesan.
- Cover with oiled foil.
- Preheat oven to 350°F. Bake lasagna, covered, 35 minutes. Uncover; bake until heated through, about 25 minutes longer.
- Let stand 10 minutes before serving.
- Serve with a fresh arugula salad!
