Directions: The Best Vegetarian Lasagna

Step 1: Sauté the Vegetables
Begin by heating the olive oil in a large skillet over medium heat. Add the onion and carrots, sautéing until they soften, about 3-4 minutes. Next, toss in the zucchini and mushrooms, cooking until they’re tender and the moisture has evaporated. Finally, stir in the spinach and cook until wilted. Season with salt and pepper to taste. Remove from heat and set aside.
Step 2: Prepare the Sauce
In a large mixing bowl, combine the crushed tomatoes, tomato sauce, and tomato paste. Stir in the Italian seasoning, sugar, and chopped basil. Taste and adjust seasoning with salt and pepper as desired.
Step 3: Cook the Noodles
In a large pot, bring salted water to a boil. Cook the lasagna noodles according to package instructions until al dente. Drain and lay them flat on a clean surface to prevent sticking.
Step 4: Mix the Cheese Filling
In a separate bowl, combine the ricotta cheese, grated parmesan, and egg. Mix until well combined, then season with a pinch of salt and pepper.
Step 5: Assemble the Lasagna
Preheat your oven to 375°F (190°C). In the bottom of a 9×13 inch baking dish, spread a thin layer of the tomato sauce. Layer 3 lasagna noodles over the sauce, followed by half of the vegetable mixture, then half of the ricotta mixture, and a third of the mozzarella cheese. Repeat the layers, finishing with a final layer of noodles topped with the remaining sauce and the rest of the mozzarella cheese.
Step 6: Bake the Lasagna
Cover the baking dish with aluminum foil (to prevent sticking, spray the foil with cooking spray) and bake for 25 minutes. Remove the foil and bake for an additional 25 minutes, until the cheese is bubbly and golden. Let the lasagna sit for 10-15 minutes before slicing to allow it to set.
No-Store Runs Needed

You might be surprised to find that you can make this lasagna without any last-minute trips to the store.
- Many of the ingredients, like canned tomatoes and pasta, are pantry staples.
- Vegetables can be swapped based on what you have in your fridge—bell peppers, eggplant, or kale can all work beautifully.
- If you don’t have ricotta, cottage cheese can be a suitable alternative.
- Feel free to use frozen spinach if fresh isn’t on hand; just thaw and drain it well before use.
Watch Outs & How to Fix
While making The Best Vegetarian Lasagna is straightforward, here are some common pitfalls and how to avoid them:
- Too watery? Ensure your vegetables are sautéed until their moisture evaporates, and consider draining the canned tomatoes.
- Sticking noodles? Always layer them with sauce in between and avoid overcooking them in the boiling water.
- Cheese too hard? If the top is browning too quickly, cover it with foil for part of the baking time.
- Flavor lacking? Adjust seasoning with additional salt, pepper, or fresh herbs to enhance the taste.
Storing Tips & Timelines
Leftover lasagna can be just as delightful as the first serving. Here are some tips to store it properly:
You can refrigerate leftovers in an airtight container for up to 4 days. For longer storage, consider freezing portions.
