Equipment

  • Baking dish
  • Sharp knife or mandoline
  • Mixing bowls
  • Saucepan (for sauce)
  • Aluminum foil

Ingredients
  

Vegetable Layers:

  • 2 medium sweet potatoes, thinly sliced
  • 1 small butternut squash, thinly sliced
  • 3 large carrots, thinly sliced

Sauce Options:

  • 3 cups creamy béchamel OR tomato-based sauce

Cheese Layer:

  • 1 cup ricotta
  • 2 cups mozzarella, shredded
  • ½ cup Parmesan, grated

Pasta:

  • 9–12 lasagna noodles (regular or no-boil)

Flavor Boosters:

  • 1 onion, diced
  • 2 cloves garlic, minced
  • Herbs: thyme, sage, basil

Optional Add-ins:

  • 2 cups spinach or kale
  • 1 cup mushrooms

Instructions
 

  • Preheat Oven: Heat oven to 375°F (190°C). Grease baking dish.
  • Prepare Vegetables: Slice sweet potatoes, squash, and carrots evenly. Roast on a sheet pan for 20 minutes until slightly tender.
  • Prepare Sauce: Make béchamel (butter, flour, milk, nutmeg) or tomato sauce with garlic, onion, and herbs.
  • Prepare Cheese Mixture: Mix ricotta with herbs, salt, and pepper.
  • Layer Lasagna: Spread sauce on bottom → add noodles → roasted vegetables → ricotta mixture → mozzarella. Repeat layers.
  • Final Layer: Top with noodles, sauce, mozzarella, and Parmesan.
  • Bake: Cover with foil and bake 30 minutes. Remove foil and bake 15 minutes until golden.
  • Rest Before Serving: Let lasagna rest 10–15 minutes before slicing for clean layers.
  • Serve: Garnish with fresh basil or parsley.

Notes

  • Roast Vegetables First: Enhances sweetness and prevents soggy layers.
  • Even Slicing: Ensures vegetables cook uniformly.
  • Season Each Layer: Light seasoning keeps flavors balanced.
  • Sauce Choice: Béchamel for creamy richness, tomato for lighter freshness.
  • Variations: Vegan with plant-based cheese, gluten-free with GF noodles, or low-carb with zucchini slices instead of pasta.
  • Storage: Refrigerate leftovers for 3–4 days; reheat in oven for best texture.
