Ingredients

  • 12 lasagna noodles, cooked according to package instructions
  • 2 large fennel bulbs, thinly sliced
  • 2 medium onions, thinly sliced
  • 4 cloves garlic, minced
  • 2 tablespoons olive oil
  • 3 cups marinara sauce (homemade or store-bought)
  • 3 cups ricotta cheese
  • 2 cups shredded mozzarella cheese
  • 1 cup grated Parmesan cheese
  • 1/4 cup fresh basil, chopped
  • 1 teaspoon dried oregano
  • Salt and pepper to taste
  • 1 tablespoon butter
  • 2 tablespoons all-purpose flour
  • 2 cups milk
  • Pinch of nutmeg (optional)

Equipment

  • Large pot for boiling noodles
  • Large skillet or frying pan
  • 9×13 inch baking dish
  • Mixing bowls
  • Whisk
  • Wooden spoon or spatula
  • Sharp knife and cutting board
  • Measuring cups and spoons

Instructions

  1. Prepare the noodles: Bring a large pot of salted water to a boil. Cook the lasagna noodles according to the package directions until al dente. Drain and lay them flat on a clean kitchen towel to prevent sticking.
  2. Caramelize the bulbs: Heat the olive oil in a large skillet over medium heat. Add the sliced fennel and onions, seasoning lightly with salt. Cook for 15-20 minutes, stirring occasionally, until the bulbs are soft and golden brown. Add the minced garlic in the last 2 minutes to avoid burning.
  3. Make the béchamel sauce: In a small saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes until it forms a paste and bubbles gently. Slowly add the milk, whisking constantly to avoid lumps. Cook until the sauce thickens, about 5 minutes. Season with salt, pepper, and a pinch of nutmeg if using. Remove from heat.
  4. Preheat your oven: Set to 375°F (190°C).
  5. Mix the ricotta filling: In a bowl, combine the ricotta cheese with half of the chopped basil, dried oregano, salt, and pepper.
  6. Assemble the lasagna: Spread a thin layer of marinara sauce on the bottom of the baking dish. Layer 3 cooked noodles over the sauce. Spread one-third of the ricotta mixture over the noodles, followed by one-third of the caramelized bulbs, a layer of béchamel sauce, a sprinkle of mozzarella, and a spoonful of marinara. Repeat this layering process two more times, finishing with noodles topped with béchamel, marinara, mozzarella, and Parmesan cheese.
  7. Bake: Cover the dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 15 minutes until the cheese is bubbly and golden.
  8. Rest and serve: Let the lasagna rest for 10 minutes before slicing. Garnish with the remaining fresh basil.

Tips & Variations

For extra flavor, try roasting the fennel and onions before caramelizing them. You can also swap the fennel for leeks or shallots for a different bulb twist.

If you prefer a meatier version, add cooked ground beef or Italian sausage to the marinara sauce. For a vegetarian option, consider adding layers of spinach, mushrooms, or zucchini.

Experiment with cheeses by adding provolone or fontina for a richer taste. Leftover lasagna can be refrigerated for up to 3 days or frozen for up to 3 months.
