Pumpkin Lasagna with Creamy Fontina –  Roasted zucchini, yellow squash, red peppers and onions layered between lasagna noodles and topped with a flavorful pumpkin-tomato sauce and shredded Fontina cheese.  This wonderful meatless recipe is perfect for Fall.  It’s a rich, hearty and delicious vegetarian dish.

Pumpkin Lasagna should really be called Vegetable Lasagna because the pumpkin in the title can be a little off-putting.  The flavor of pumpkin is extremely subtle and gives a nice, light sweetness to the sauce.

When I originally made this recipe, I roasted the zucchini, yellow squash and red peppers in the oven while I caramelized the onions on the stove.  After making Pumpkin Lasagna many times, I’ve come to the conclusion that caramelizing the onions isn’t necessary.  Instead, I add the onions and a couple cloves of chopped garlic to the pan with all the other vegetables and roast them all together.  I love the taste of roasted vegetables, especially roasted onions and this not only saves time but I love the taste.

Here’s all you do…

Slice zucchini, yellow squash, red peppers, onions and garlic and place them in a baking pan.  Drizzle olive oil over the top and add salt and pepper.  Use your hands to make sure the olive oil is evenly distributed over the vegetables.  Place them in the oven to roast for 15 minutes.

While the vegetables are roasting, mix together the ricotta, parmesan cheese, an egg, sage, parsley, salt, and pepper.

Transfer to the oven and bake uncovered until sauce is bubbly and the cheese is melted, 45 to 50 minutes.

One of the things I love most about this recipe is the fact that it’s meatless.  It’s a lighter, healthier option that’s easier to prepare than traditional lasagna.  The pumpkin in the sauce is subtle and not overpowering and the fontina cheese goes perfectly with the pumpkin.

A 9 x 13 baking dish is the perfect size dish to use with this recipe but it can also be divided between two smaller baking dishes.

This comforting Pumpkin Lasagna with Fontina is a wonderful vegetarian dish.  Using canned pumpkin in your favorite spaghetti sauce gives the lasagna a subtle pumpkin flavor.  It’s a perfect dish for fall.

  1. I agree with you that roasted vegetable lasagna is fabulous. And using pumpkin as part of the sauce is a lovely touch – will have to try it.

  2. Looks awesome…I LOVE fontina cheese, but then again I love all cheese…I’m coming over for dinner!
