Instructions

  1. Step 1: Preheat oven to 375°F. In a small saucepan, heat 1 tbsp olive oil over medium heat. Add 1 cup marinara sauce and 1 cup carrot puree, and simmer for 5 minutes until well combined. Season with 1/4 tsp salt and 1/8 tsp black pepper.
  2. Step 2: Spread 1/2 cup of the sauce mixture evenly in the bottom of a 9x13-inch baking dish. Place 4 lasagna noodles on top.
  3. Step 3: Spread 1/2 cup ricotta cheese over the noodles, then sprinkle with 1/2 cup cooked lentils. Top with 1/2 cup of the sauce mixture and 4 more noodles. Repeat layers: sauce, ricotta, lentils, sauce, and noodles until all ingredients are used, ending with a layer of sauce and 1/2 cup shredded mozzarella cheese on top.
  4. Step 4: Sprinkle with 1/4 cup grated Parmesan cheese. Bake for 30 minutes until bubbly and golden. Let rest for 10 minutes before serving.
