Preparation: Begin by preheating your oven to 375°F (190°C). In the meantime, cook your whole wheat lasagna noodles according to the package directions. Drain and set aside.
Veggies Galore: In a large pan, heat the olive oil over medium heat. Once hot, add in your sliced zucchini and diced red bell pepper. Sauté until they’re slightly tender – usually about 5 minutes.
Spinach Time: Toss in the chopped spinach to the pan and continue cooking until it’s wilted. This should take around 3 minutes.
Cheesy Blend: In a bowl, combine the ricotta cheese with half of the chopped basil leaves. Mix well, adding a pinch of salt and pepper for flavor.
Layering Begins: Grab a baking dish and spread a thin layer of the tomato sauce on the bottom. Place a layer of cooked lasagna noodles over the sauce. Spread a portion of the ricotta mix on the noodles, followed by a layer of the sautéed veggies.
Repeat: Continue layering in the same sequence: sauce, noodles, ricotta mix, and veggies. Finish with a layer of noodles on top.
Final Touch: Pour the remaining tomato sauce over the top layer of noodles. Sprinkle generously with shredded mozzarella cheese.
Bake: Place the dish in your preheated oven and bake for about 30 minutes, or until the cheese turns a lovely golden brown.
Rest & Serve: Once out of the oven, let your Healthy Lasagna sit for about 10 minutes. This helps in settling the layers. Slice and serve garnished with the remaining fresh basil.
