Step-by-Step Instructions

Step 1 — Prepare the Vegetables

Chop 1 onion, 2 carrots, and 2 celery stalks into small, even pieces. Mince 3 cloves of garlic. Sauté the onion, carrots, and celery in 2 tablespoons of olive oil over medium heat until softened, about 5–7 minutes. Add the minced garlic and cook for another minute until fragrant.

Step 2 — Cook the Tomato Sauce

Add two 28-ounce cans of crushed tomatoes to the softened vegetables. Stir in 1 teaspoon of dried oregano, 1 teaspoon of dried basil, and salt and pepper to taste. Let the sauce simmer uncovered for 20–25 minutes, stirring occasionally, until it has thickened slightly.

Step 3 — Make the Ricotta Filling

In a medium bowl, combine 16 ounces of ricotta cheese, 1 large egg, 1/2 cup of grated Parmesan cheese, and 1/4 cup of chopped fresh parsley. Mix until well combined. For a smoother filling, you can use a food processor to blend the ingredients briefly.

Step 4 — Assemble the Lasagna Layers

Spread a thin layer of tomato sauce on the bottom of a 9×13-inch baking dish. Place a single layer of no-boil lasagna noodles over the sauce. Top with 1/3 of the ricotta mixture, spreading it evenly, followed by 1/3 of the remaining sauce. Repeat the layers two more times, finishing with a layer of sauce.

Step 5 — Add the Final Cheese Topping

Sprinkle 2 cups of shredded mozzarella cheese evenly over the top layer of sauce. For a golden, bubbly finish, you can also add an extra 1/4 cup of grated Parmesan cheese over the mozzarella.

Step 6 — Bake the Vegetarian Lasagna

Cover the baking dish with aluminum foil and bake in a preheated 375°F (190°C) oven for 25 minutes. Then, remove the foil and bake for another 15–20 minutes, or until the cheese is melted and lightly browned and the edges are bubbly.

Step 7 — Rest Before Serving

Let the Vegetarian Lasagna rest for 10–15 minutes after removing it from the oven. This allows the layers to set, making it easier to cut neat portions. Serve warm, garnished with fresh basil if desired.

Common Mistakes to Avoid

• Mistake: Using watery vegetables like zucchini or mushrooms without pre-cooking. Fix: Sauté them first to evaporate excess moisture, preventing a soupy Vegetarian Lasagna.
• Mistake: Overloading the lasagna with too many layers or fillings. Fix: Stick to 3–4 balanced layers so it cooks evenly and holds its shape when sliced.
• Mistake: Skipping the salt when boiling no-boil noodles. Fix: Salt the sauce well instead, as the noodles absorb liquid and seasoning directly from it.
• Mistake: Not letting the lasagna rest after baking. Fix: Wait 15–20 minutes before serving; this allows the layers to set for cleaner slices.
• Mistake: Using only one type of cheese for the filling. Fix: Combine ricotta with an egg and grated Parmesan for better binding and flavor depth.
• Mistake: Baking at too high a temperature, causing the top to burn. Fix: Cover with foil for most of the bake, removing it only at the end for browning.
• Mistake: Underseasoning the tomato sauce because vegetables dilute flavor. Fix: Taste and adjust seasoning after mixing in all vegetables.
• Mistake: Using a thin, runny sauce that makes layers slide apart. Fix: Simmer your sauce longer to thicken it, ensuring sturdy, defined layers.

Storing Tips

• Fridge: Store leftover Vegetarian Lasagna in an airtight container for up to 5 days.
• Freezer: Wrap tightly or place in a freezer-safe container for up to 3 months.
• Reheat: Thaw if frozen, then bake at 350°F until the internal temperature reaches 165°F.

Always cool your Vegetarian Lasagna to room temperature before refrigerating or freezing to maintain texture and food safety.
