I ganked this one straight from my husband, who ganked it from light cooking’s website. (Don’t quote me on that. I am a total recipe plagiarizer, apparently.) I found this recipe to be very time-consuming. I’m guessing partly because I could not find organic whole wheat no-bake lasagna noodles. This is one of those recipes you may want to make on a Sunday and freeze for pulling out on a busy week night. In any case, it is very hearty and has a rich, nutty flavor. I will make it again. When I have an entire afternoon at my disposal.
Butternut Squash Lasagna
Time Savers: Roast the squash and caramelize the onions the night before. You can refrigerate each until you’re ready to put the lasagna together.
Ingredients
1 medium butternut squash (about 2 lbs)
2 tsp olive oil, divided
3 medium Spanish onions, thinly sliced
1 cup low fat ricotta cheese
1/8 tsp ground nutmeg
4 large egg whites
1/4 cup fresh grated Parmesan cheese
10 sage leaves, finely chopped
1/8 tsp sea salt
fresh ground black pepper to taste
2 cups part-skim fresh mozzarella
2 and 1/2 cups marinara sauce
1/2 lb. oven ready whole wheat lasagna
1/3 cup coarsely chopped walnuts, toasted
Preparation
Preheat oven to 375 degrees.
Cut squash in half lengthwise and scoop out seeds Lightly brush cut sides with 1 tsp olive oil and place, cut sides down, onto a parchment lined baking tray. Bake in oven for 25 minutes, until squash is tender when pierced with a fork. Remove from oven and let cool to room temperature.
Meanwhile, heat remaining 1 tsp olive oil in a large saute pan over medium-high heat. Add onions, stir and saute for 2-3 minutes, until onions begin to soften. Reduce heat to medium-low and continue to cook for about 40 minutes, stirring frequently, until onions are very soft and golden brown. Remove from heat and set aside until cooled to room temperature.
Scoop out flesh of squash into the bowl of a food processor. Add ricotta, nutmeg, egg whites and Parmesan and process until smooth. Add sage and season with salt and pepper. Transfer mixture to a large mixing bowl and gently fold in caramelized onions.
Reserve 1/2 cup mozzarella, cover and refrigerate until needed.
Assemble lasagna:
Cover bottom of 9×13 inch casserole dish with about 1/2 cup marinara sauce. Top with a single layer of lasagna noodles, overlapping slightly, then 1 cup butternut squash mixture and 1/2 cup mozzarella. Repeat layers once, starting with 1/2 cup marinara sauce. Sprinkle walnuts evenly over mozzarella. Repeat layers once again. Finish with 1/2 cup marinara sauce, a layer of noodles, remaining butternut squash mixture, and remaining marinara sauce.
Cover dish with foil, place onto a baking tray and bake in oven for 45 minutes at 375 degrees. remove foil, top lasagna with reserved 1/2 cup of mozzarella and bake an additional 15 minutes.
Remove lasagna and allow to sit for 15 minutes. Serve in bowls with bottoms coated in about 2 tbsps heated marinara. Garnish with parsley or fresh basil.
