I have been up to my eyeballs in renovations around here the past couple weeks, so there is some appeal to making a light meatless recipe with many servings like this Butternut Squash Lasagna. I still have a few days of painting left in my kitchen and pantry, so being able to zap a healthy homemade meal will come in very handy. The recipe is an older (2003) one from Cooking Light, which seems appropriate since they are celebrating the 25th anniversary of the magazine . Here is a link to the original recipe. I made a few adjustments to the recipe, such as sauteing in olive oil, swapping chives for parsley , baking in one large pan, and a few other minor changes, but the recipe is still quite similar to the original.

Butternut Squash Lasagna: Recipe Tricks

I used jarred sauce, and added a teaspoon of smoked olive oil rather than making the Smokey Marinara sauce for the recipe. I doubt many readers have smoked oil on hand, so I would suggest using the Smokey Marinara Sauce recipe that Cooking Light suggests. If you are really in an all fire hurry, add some leftover roasted butternut squash as a layer in my easy Ravioli Lasagna recipe.

This Butternut Squash Lasagna was rather tasty. I will make it again.
If you are looking to create a hearty vegetarian holiday spread consider making this along with my Eggplant Casserole, Beet and Dandelion Salad,Puff Pastry Pizza with Vegetables and Potato Leek soup.

  • 1 teaspoon salt
  • ½ teaspoon freshly ground black pepper
  • 2 large eggs
  • 1 32-ounce container part-skim ricotta cheese
  • 3 cups diced peeled butternut squash
  • 6 cups Smoky Marinara I used jar sauce and added smoked olive oil to it, but the sauce looks good & most people don't have smoked olive oil in their pantry
  • 12 oven-ready lasagna noodles such as Barilla
  • ¼ cup grated Parmesan cheese


  • Preheat oven to 375°.

  • Place large deep pan such as a Dutch oven over medium-high heat.

  • Spread about ½ the cheese mixture over noodles.

  • Spread the spinach-onion mix, over cheese evenly.

  • Top with a couple scoops of sauce.

  • Add a noodle layer.

  • Spread remaining cheese on noodles. (Be mindful of height, and don't use it all if the room isn't there. You still have more to add)
