Butternut Squash and Spinach 3-Cheese Lasagna is a cozy, comforting vegetarian lasagna layered with creamy roasted squash purée, garlicky spinach, and three cheeses—ricotta, mozzarella, and Parmesan. Perfect for fall dinners, potlucks, or meal prep.

Ingredients

  • 4 cups butternut squash, peeled and cubed
  • 2 tbsp olive oil or butter
  • 1/2 cup milk or cream
  • 1/4 tsp nutmeg
  • Salt and pepper, to taste
  • 1 medium onion, chopped
  • 2 cloves garlic, minced
  • 5–6 cups fresh spinach (or 10 oz frozen, thawed and drained)
  • 1 1/2 cups ricotta cheese
  • 2 cups shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • 9–12 lasagna noodles (no-boil or pre-cooked)
  • Optional: fresh sage or thyme for extra flavor

Instructions

  1. Preheat oven to 400°F (200°C). Toss squash cubes with 1 tbsp olive oil, salt, and pepper. Roast for 25–30 minutes until soft and caramelized.
  2. Blend roasted squash with milk or cream, nutmeg, salt, and pepper until smooth. Set aside.
  3. In a skillet, sauté onion and garlic in 1 tbsp olive oil until soft. Add spinach and cook until wilted (or warmed through if using frozen).
  4. In a bowl, mix ricotta with 1/4 cup Parmesan, salt, and pepper.
  5. Lower oven temp to 375°F (190°C). Grease a baking dish.
  6. Assemble lasagna: spread a layer of squash purée, then noodles, ricotta mixture, spinach, and mozzarella. Repeat layers, ending with mozzarella and remaining Parmesan on top.
  7. Cover with foil and bake for 30 minutes. Uncover and bake an additional 10–15 minutes until bubbly and golden.
  8. Let rest for at least 10 minutes before slicing and serving.

Notes

  • Frozen squash can be used; roast or steam and purée well-drained.
  • Use gluten-free noodles or roasted zucchini slices for a gluten-free version.
  • Add mushrooms or substitute kale for the spinach if desired.
  • A layer of béchamel adds extra richness.
  • Wrap tightly and freeze baked or unbaked for future meals.
