How to make Butternut Squash Lasagna with Sage
Preparing the Butternut Squash
The original recipe uses a whole butternut squash, which is then peeled, cubed and roasted. Many grocery stores carry pre-cubed butternut squash. You’ll need about 3 pounds prepared squash, or a whole squash that’s approximately 3 1/2 pounds. If you’re using a whole squash, peel, seed and cube the squash.
Roast the squash
Once you’ve cubed the squash, toss it with olive oil and kosher salt and pepper and roast the cubes at 425 degrees F. for about 25 minutes, or until it is tender. The time will depend on how large or small the cubes are, so test them at 20 minutes.
Prepare the lasagna filling
There are two fillings that make up the layers of this lasagna. First the cooked squash is partially mashed so that it retains some small chunks. The cooked squash is mixed with chicken broth and chopped sage leaves that are cooked in browned butter. You can mash the squash with the back of a spoon, or use your hands. You’ll want some small chunks of squash in the mixture.
The second filling is a combination of ricotta, cream, egg yolks and fresh mozzarella cut into cubes, and chicken or vegetable broth. To save time, you can also use pre-shredded mozzarella.
Martha uses fresh lasagna noodles. If you’re feeling very ambitious, you can make your own lasagna noodles, or use no-boil lasagna noodles. If you do use no-boil noodles, you’ll need to increase the amount of chicken broth by 1/2 cup.
Assembling the lasagna
Once you’ve prepared the butternut squash and ricotta fillings, you are ready to assemble.
- Start with a thin layer of ricotta mixture on the bottom of the pan.
- Add a layer of noodles. If they don’t fit perfectly, you can break them to fit.
- Spread 1/2 of the butternut and sage mixture over the noodles.
- Add another layer of noodles.
- Spread about 1 cup of ricotta mixture over noodles.
- Repeat, noodles, squash, noodles, ricotta.
- Top ricotta mixture with grated parmesan cheese.
I hope you enjoy this delicious autumn lasagna!

Butternut Squash Lasagna with Sage
Butternut squash filling
- 1 pound whole-milk ricotta cheese
- 1/2 cup heavy cream
- 2 large eggs yolks
- 1/2 pound fresh mozzarella cheese cut into chunks (or shredded)
- 1 teaspoon Freshly grated nutmeg... I used ground
- fresh lasagna noodles or no-boil (see note above about stock)
- 4 ounces Parmesan cheese grated
Preparing the squash
- Preheat oven to 425* F. Toss squash, 2 Tablespoons oil, and 1 teaspoon salt on a baking sheet. Season with pepper. Bake until light gold and tender, 25 to 30 minutes. Let cool.
- Melt butter in a small saute pan over medium-high heat. As soon as it starts to sizzle, add sage and cook until light gold and slightly crisp at edges, 3 to 4 minutes.
- Place squash in a medium bowl and mash 1/2 with the back of a wooden spoon. (I use my hands to do this) Leave the other 1/2 of the squash in small chunks. Gently stir in sage-butter mixture and chicken or vegetable broth. Season with 1 teaspoon salt and 1/4 teaspoon white pepper.
- Reduce oven temperature to 375* F. Combine ricotta, cream, yolks, mozzarella in a medium bowl. Season with 1/2 teaspoon salt and 1/4 teaspoon white pepper and pinch of nutmeg.
- Spread 3/4 cup of ricotta mixture in a 9 cup baking dish. Top with a layer of noodles. Spread 1/2 of the butternut squash mixture over the noodles. Top with a layer of noodles. Spread 1 cup of ricotta mixture over noodles. Repeat layering once more, (noodles, squash, noodles, ricotta) Sprinkle Parmesan over ricotta mixture.
- Place baking dish on a rimmed baking sheet and cover with foil. Bake until cheese is golden and bubbling, 30 to 35 minutes. Let stand for 15 minutes before serving.
- To save time, use pre-cubed butternut squash and pre-shredded mozzarella cheese.
- To make this completely vegetarian, substitute the chicken broth for vegetable stock.
- In place of fresh noodles, you can substitute no-boil noodles. If using no-boil noodles, increase chicken or vegetable stock by 1/2 cup.
