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.
This recipe was originally published on November 2013. Since it’s technically “Pumpkin Season”, I thought it would be a good idea to revisit this spectacular recipe and post a few updated pictures and recipe notes.
I’m at a point in my life where clutter makes me crazy. Lately, I’ve been going through closets, over-stuffed drawers and unopened boxes in the attic purging things I don’t use anymore. I guess I’m looking for simplicity and order in my life. I want to get rid of the things that have no meaning or purpose to me and create a feeling of disorder. One thing I can’t seem to part with are old magazines though, specifically food and cooking magazines. I’m not a magazine hoarder, I’d like to think of myself more of as a collector.
Last year, I came across a wonderful Pumpkin Lasagna with Fontina recipe from Williams-Sonoma in one of my magazines. The “pumpkin” really caught my eye and I bookmarked it to try later.
As often happens, I put the magazine aside and completely forgot about it. But the other day, as I was going through my magazine stack and deciding which magazines to donate to our local library and which ones to keep, I found the bookmarked page. Since it sounded as good, if not better than I remembered, I decided to make it.
The recipe calls for Pumpkin Parmesan Pasta Sauce from Williams-Sonoma but apparently, Williams-Sonoma doesn’t make this sauce any longer. It wasn’t a problem, I combined a little canned pumpkin and a handful of grated parmesan cheese with a jar of tomato sauce and created it myself.
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When I originally made this recipe, I roasted the zucchini, yellow squash and red peppers in the oven while I caramelized the onions on the stove.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.
In another bowl, combine the tomato sauce with 1/2 cup of canned pumpkin, grated parmesan cheese, and shredded fontina cheese.
Spread 1/2 cup of the pasta sauce in an even layer on the bottom of a baking dish and arrange a layer of cooked lasagna noodles on top, tearing them as needed to fit.
Spread 1/2 cup of the ricotta mixture on the noodles.
Scatter a cup of the roasted vegetables on top.
Spread 1/2 cup of pasta sauce over the vegetables.
Add 1/2 cup of shredded fontina cheese and layer the noodles, ricotta, vegetables, and sauce 1 or 2 more times, depending on the size of your baking dish.
Top with remaining noodles, sauce and fontina.
Transfer to the oven and bake uncovered until sauce is bubbly and the cheese is melted, 45 to 50 minutes.
Sprinkle the remaining parsley over the top and let the pumpkin lasagna rest for 15 minutes before serving.
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.
