How to make easy Healthy Butternut Squash Lasagna
Slice and roast the squash – You will need a squash that is 1.5-2 lbs. Cut the ends off of the squash, peel it, remove the seeds, and slice it into 1/4 inch size pieces. Lay the squash onto a sprayed baking sheet, drizzle the squash with olive oil, sprinkle with salt and pepper and bake for 15 minutes at 425 degrees F. Remove and let cool for a few minutes.
While the squash is roasting, you can make the creamy saucy filling and sauté the spinach.
Sauté the spinach in a skillet on the stove at low-medium heat for a few minutes until it is slightly wilted.
Make the creamy filing – Add some butter to a medium-size saucepan. Once it melts add in the flour (I used whole wheat white flour). Whisk the flour in with the butter for a minute or so, then add in the coconut milk about a 1/2 cup at a time, whisking lightly. Add in the nutmeg and a bay leaf. Simmer on low for 5 minutes or so to thicken the sauce. Remove from the heat. Let it cool for a couple of minutes.
Combine the ricotta with lemon zest, freshly chopped sage and rosemary, parmesan, mozzarella, salt and pepper, and mix.
Time to assemble – the best part!
Reduce the oven temperature to 400 degrees F and spray a 9×13 baking dish with cooking spray. Ladle on some of the white cream sauce, enough to cover the bottom of the pan, and add a layer
Next layer on some of the sautéed spinach.
Add some of the ricotta mixture and spread it evenly over the squash and spinach.
Pour some more of the creamy white sauce all over to evenly cover the ricotta mixture. Repeat with one more layer then finish the final layer with lasagna noodles, the remaining creamy white sauce, the remaining cooked spinach and a good sprinkle of parmesan cheese.
Bake for 35 minutes, until the top, is nice and golden brown and bubbly. Remove and let cool for at least 30 minutes before serving.
Slice and serve! Super creamy, but still light and healthy. My new favorite lasagna for fall!
Tips for making this butternut squash lasagna
- Choose a squash with a longer neck since you want long “plank” pieces to layer in the lasagna. You can also just cut large slices of squash if you cannot find one with a long neck.
- No boil lasagna noodles, lentil lasagna noodles, or store-bought lasagna sheets all work well in this recipe. You can also use whole wheat lasagna noodles, but those would need to be boiled first.
- Bake the lasagna uncovered, this allows it to get nice and golden brown on top and all around the edges.
- Let the lasagna cool for at least 30 minutes before slicing and serving. Letting it cool allows the slices to be lifted from the pan easier as well as results in perfectly square pieces of lasagna (see picture above).
