This Butternut Squash Lasagna is the ultimate fall comfort food just like any soothing Italian pasta dish. Yet this version of a classic is a vegetarian option, as compared to say, this regular lasagna made in the crockpot, our Slow Cooker Easy Lasagna recipe which I simply adore just as much.

Personally, I haven’t warded off meat, I just love the food group too much. Yet my oldest has been red-meatless for a very long time now. Truth be told, when I make vegetarian meals, it’s only because I need a break from chicken and pork.

Whether that is filling the heart that’s missing red meat more often, well, that’s another topic. Spoiler: not really, but.

I make quite a bit of chicken and pasta dishes, and you’ll find many here on the blog. If you’re new and unfamiliar, I’d suggest starting with these Chicken and Spinach Cannelloni Rolls.

Yet this particular recipe is impressive and has room to suit tastes, so if you want to add chicken, go right ahead. You can also add some fresh spinach if you wish – yet of course this recipe is divine as is.

Melt butter in a medium saucepan or large skillet on the stove, over medium-high heat. As soon as it starts to sizzle, add the fresh sage and cook until golden and crisp at the edges, about 3-4 minutes.

Place the squash in a medium bowl and mash 1/2 of it with the back of a wooden spoon leaving the other 1/2 in whole pieces. Gently stir in sage-butter mixture and vegetable stock. Season with black pepper at this time if you wish. 

Spray nonstick cooking spray to the bottom of the dish. Spread 3/4 cup of ricotta mixture into a thin layer, on the bottom of the casserole dish. Top with a single layer of lasagna noodles. Then spread 1/2 of the butternut squash mixture over noodles. Top with a layer of noodles. Spread more ricotta mixture over noodles.

Repeat layers once more if you can (the layers are noodles, squash, noodles, ricotta). Sprinkle reserved cheese mixture as a final layer to finish.

Place baking dish on a rimmed large baking sheet to catch excess, and bake until cheese is golden brown and bubbling, about 30-35 minutes. Let stand for 15 minutes then slice and serve. Enjoy!

Storage and Leftovers: Cover leftovers with plastic wrap or aluminum foil and refrigerate for up to 4 days. This Vegetarian Lasagna is really good the next day. Just heat thoroughly before enjoying.

While I was never a solid fan of squash, I’ve been trying hard to crush on this type of vegetable since it’s so full of vitamins and low in both fat and carbs.

This butternut lasagna has a sweet and nutty taste in comparison to potatoes and can be made in both sweet and savoury dishes depending on the spices blended with it.

I made Roasted Maple Cinnamon Butternut Squash for a great side dish alternative to potatoes. This one brings out the sweet, so it was only given that I try more of a savoury dish for this versatile ingredient.
