Welcome back to My Cozy Kitchen, friends! If the thought of bubbling cheese, tender noodles, and roasted veggies wrapped in a silky béchamel makes your heart skip a beat—you’re in the right place. This lasagna isn’t just delicious, it’s a feel-good feast wrapped in joy, finished with a zingy basil vinaigrette that cuts through the richness like magic. Whether it’s a snowy Sunday or a potluck showstopper, this one’s a keeper.


Ingredients

Scale

Béchamel Sauce

  • 1 cup unsalted butter

  • 1 cup all-purpose flour

  • 8 cups milk (whole preferred)

  • 2 cups grated Parmesan

  • Pinch of nutmeg

  • Salt & pepper to taste

Vegetable Filling

  • 8 tbsp olive oil

  • 2 yellow onions, diced

  • 4 large carrots, diced

  • 8 cups chopped mixed veggies (zucchini, squash, mushrooms, etc.)

  • 48 oz marinara sauce

  • 2 cups grated Parmesan

Lasagna Assembly

  • 2 (18 oz) packs no-boil lasagna noodles

  • 3 lbs shredded mozzarella

  • 2 cups grated Parmesan

Basil Vinaigrette (optional but magic!)

  • 1 cup fresh basil

  • ½ cup olive oil

  • 2 tbsp lemon juice

  • Salt to taste

  • Blend all until smooth


Instructions

  • Make Béchamel: Melt butter, whisk in flour. Cook 2 mins. Slowly add warm milk, whisking until smooth. Simmer 10 mins until thick. Stir in Parmesan, nutmeg, salt, and pepper.

  • Cook Veggies: Sauté onions/carrots 5 mins. Add veggies, cook 12–15 mins until tender. Stir in marinara and Parmesan. Simmer 5 mins.

  • Assemble: Preheat oven to 375°F. In a 9×13” dish, layer: noodles → ⅓ veggie mix → ⅓ béchamel → 1 cup mozzarella + ¼ cup Parmesan. Repeat twice. Finish with noodles, béchamel, mozzarella, Parmesan.

  • Bake: Cover with foil. Bake 40 mins. Uncover and bake 15–20 mins more until bubbly and golden. Rest 15 mins. Drizzle basil vinaigrette before serving.

Notes

  • Dry those veggies! Sauté until all moisture is gone—soggy lasagna is a no-go.

  • No béchamel? Use cashew cream or store-bought white sauce.

  • Make-ahead winner: Assemble, cover, and chill. Bake fresh when ready!
