1-First Step: Start by preheating your oven to 425 degrees Fahrenheit. This high heat helps the noodles cook perfectly and browns the top nicely, so give it time to reach the right temperature while you prep.

2-Second Step: Heat 2 tablespoons of extra-virgin olive oil in a large skillet over medium heat. Once it’s warm, add the chopped carrots, red bell pepper, zucchini, yellow onion, and ¼ teaspoon salt. Stir occasionally and cook until the vegetables turn golden on the edges, which takes about 8 to 12 minutes, building a flavorful base for your veggie lasagna.

3-Third Step: Add the baby spinach in batches to the skillet. Cook and stir until it wilts completely, about 3 minutes in total. Then, remove the skillet from the heat to keep the veggies fresh and ready for the next stage.

4-Fourth Step: Drain any excess juice from the 28-ounce can of diced tomatoes using a mesh sieve. Transfer the tomatoes to a food processor, then add ¼ cup chopped fresh basil, 2 tablespoons extra-virgin olive oil, 2 cloves of garlic, ½ teaspoon salt, and ¼ teaspoon red pepper flakes. Pulse this mixture about 10 times until it reaches a spreadable consistency, creating a homemade sauce that’s full of veggie lasagna goodness.

5-Fifth Step: Take half of the cottage cheese (1 cup or 8 ounces) and blend it in the food processor until it’s smooth. Move this to a large mixing bowl for easy combining later.

6-Sixth Step: Pulse the cooked vegetable and spinach mixture in the food processor 5 to 7 times until it’s finely chopped but not pureed. Mix this with the blended cottage cheese in the bowl, then stir in the remaining cottage cheese (1 cup or 8 ounces), ¼ to ½ teaspoon salt, and freshly ground black pepper to taste. This step makes a creamy filling that’s packed with veggies.

7-Seventh Step: In a 9×9-inch baking dish, spread ½ cup of the tomato sauce on the bottom. Layer 3 lasagna noodles on top, breaking or overlapping as needed, then add half the cottage cheese-veggie mixture, ¾ cup tomato sauce, and ½ cup shredded mozzarella cheese. This builds the first layer of your veggie lasagna for even baking.

8-Eighth Step: Add another 3 noodles, the rest of the cottage cheese-veggie mixture, and ½ cup mozzarella cheese on top. Skip the sauce here to keep the middle layers moist, ensuring the flavors meld without sogginess.

9-Ninth Step: Finish with the remaining 3 noodles, spread ¾ cup tomato sauce evenly, and top with 1 cup shredded mozzarella cheese. Cover the dish with parchment paper or foil, making sure it doesn’t touch the cheese, then bake covered for 18 minutes.

10-Tenth Step: Remove the cover, rotate the dish 180 degrees, and bake uncovered for 10 to 15 minutes until the top is spotty brown and bubbly. Let it cool for 15 to 20 minutes before slicing to allow it to set properly.

11-Final Step: Garnish with extra fresh basil and serve warm.
