Tasty No Noodle Vegetable Lasagna

Here is my take on a no noodle vegetable lasagna, made with layers of fresh zucchini, tender eggplant, and a rich homemade tomato sauce, all topped with melty mozzarella and Parmesan cheese.

This veggie-packed lasagna has become my go-to dinner for weeknight meals. I often make a double batch and freeze one for later because my family loves having it on hand. Who says comfort food can’t be good for you too?

What Kind of Zucchini Should I Use?

Medium-sized zucchini are your best bet for this no-noodle lasagna since they’re easier to slice into even, lasagna-like strips. Look for zucchini that are about 6-8 inches long and feel firm when you give them a gentle squeeze. While both green and yellow summer squash will work, traditional dark green zucchini tend to hold their shape better during baking. When slicing, aim for strips about 1/4 inch thick – any thinner and they might fall apart, any thicker and they’ll release too much water into your lasagna. If your zucchini seems extra watery, you can lay the slices on paper towels and sprinkle them with a little salt for 10-15 minutes before using them in your recipe.

Options for Substitutions

This low-carb lasagna is pretty flexible with substitutions. Here’s what you can swap:

• Vegetables: You can mix and match your veggie ‘noodles’ based on what you have. Try yellow squash instead of zucchini, or use sliced portobello mushrooms instead of eggplant. Just make sure to slice them thinly and remove excess moisture before layering.
• Ricotta cheese: If you’re not a fan of ricotta or can’t find it, try cottage cheese (drain and blend until smooth) or a mixture of cream cheese and Greek yogurt (use equal parts of each).
• Egg yolks: While eggs help bind the cheese layer, you can use 2 whole eggs instead of 4 yolks. For an egg-free version, try adding 2 tablespoons of cornstarch to the ricotta mixture.
• Marinara sauce: Any good quality pasta sauce works here. You can even use homemade sauce or crushed tomatoes seasoned with Italian herbs.
• Cheese blend: Feel free to play with different cheese combinations – provolone, fontina, or asiago work great. Just keep a mix of hard and melting cheeses for the best texture.

Watch Out for These Mistakes While Cooking

The biggest challenge when making no-noodle vegetable lasagna is dealing with excess moisture from the vegetables, which can make your lasagna watery – solve this by salting your sliced vegetables and letting them sit for 30 minutes, then patting them dry with paper towels before assembling.

Another common mistake is skipping the step of pre-cooking the vegetables, but raw vegetables release too much water during baking and won’t give you that perfect tender-crisp texture – take the time to grill or roast them lightly before layering.

To prevent a runny ricotta layer, make sure to thoroughly mix the egg yolks with the ricotta, and avoid using low-fat versions which contain more water.

For the best texture and easy serving, let your lasagna rest for at least 15-20 minutes after baking – this allows the layers to set properly and makes it much easier to cut clean slices without everything sliding apart.

What to Serve With No Noodle Vegetable Lasagna?

Since this lasagna is already packed with veggies, I like to focus on simple sides that complement without overwhelming the main dish. A fresh arugula salad dressed with lemon juice and olive oil makes a perfect light starter, while garlic bread or warm focaccia is great for soaking up any extra sauce. If you’re feeding a bigger crowd, try adding some Italian-style meatballs on the side – they’re especially good for friends or family members who might want something a bit heartier. For a super easy option, just toss some cherry tomatoes and fresh basil with a drizzle of balsamic glaze and serve it alongside the lasagna.

Storage Instructions

Keep Fresh: This veggie lasagna is perfect for leftovers! Place it in an airtight container and keep it in the fridge for up to 4 days. The flavors actually get better as they meld together, making it a great make-ahead meal for busy weeknights.

Freeze: You can freeze this lasagna either before or after baking. If freezing unbaked, wrap it tightly in plastic wrap and foil and freeze for up to 3 months. For baked leftovers, cut into portions and store in freezer-safe containers for up to 2 months. This makes meal prep super easy!

Reheat: To warm up refrigerated portions, pop them in the microwave for 2-3 minutes or heat in the oven at 350°F for about 15-20 minutes. If reheating from frozen, thaw overnight in the fridge first. Cover with foil while reheating to keep the cheese from drying out.

• Calories: 1800-2000
• Protein: 80-90 g
• Fat: 120-140 g
• Carbohydrates: 90-100 g

Ingredients

For the vegetables:

• 2 bell peppers (any color, sliced into 1/4-inch strips)
• 1 zucchini, sliced lengthwise (about 1/8-inch thick)
• 1/2 eggplant, sliced lengthwise (about 1/4-inch thick)

For the ricotta mixture:

• 15 oz whole milk ricotta (for a creamier texture)
• 1/4 cup chopped parsley (freshly chopped for best flavor)
• 4 egg yolks

Other ingredients:

• 1 cup grated Parmesan cheese
• 1 cup shredded mozzarella cheese (whole milk preferred for better melt)
• 28 oz marinara sauce (I like Rao’s Homemade Marinara)

Step 1: Prepare the Oven and Baking Dish

Preheat your oven to 400°F (200°C).

Spray a baking dish with nonstick cooking spray to prevent the layers from sticking during baking.

Step 2: Prepare and Blanch the Vegetables

Start by thinly slicing the eggplant and zucchini lengthwise, ideally using a mandoline for uniform thickness.

For the peppers, cut off the tops and bottoms to form a wide tube, then slice in half to create flat pieces.

Bring a large pot of water to a boil, add the peppers, and boil for 6 minutes.

Remove them, let cool, and peel the skins if possible.

Alternatively, microwave the peppers for 5 minutes, although the skins may not come off as easily.

Set aside the prepared vegetables.

Step 3: Prepare the Ricotta Mixture

In a bowl, mix together ricotta cheese, egg yolks, and parsley.

Stir until well combined.

Set this mixture aside as it will be used in the layering process.

Step 4: Assemble the Vegetable Lasagna Layers

Begin by placing a layer of eggplant slices on the bottom of the prepared baking dish.

Top the eggplant with 1/3 of the ricotta mixture, followed by 1/3 of the tomato sauce.

Sprinkle 1/3 cup of Parmesan cheese and 1/3 cup of mozzarella over the sauce.

Next, add a second layer using zucchini slices, followed by more ricotta, sauce, and cheese.

For the final layer, use the prepared peppers, then add the remaining ricotta, sauce, and cheeses on top.

Step 5: Bake the Lasagna

Cover the assembled lasagna with foil and place it in the preheated oven.

Bake for 30 minutes, then remove the foil and continue to bake for an additional 15 minutes, or until the top becomes browned and the cheeses are melted.

Check the tenderness of the vegetables with a fork; adjust cooking time based on their thickness.

Step 6: Rest, Serve, and Enjoy

Allow the lasagna to stand for 15 minutes after baking to let it set before cutting and serving.

Pair the lasagna with a green salad and, if desired, a piece of crusty bread (consider a gluten-free option if necessary).

Enjoy your wholesome and hearty vegetable lasagna!
