I just made a Homemade Vegetable Lasagna that looks like a creamy oven-baked cheat but actually hides a brilliant veggie swap you’ll want to steal.

Jump to Recipe

I’m obsessed with this easy, creamy mess of a lasagna. I love that it tastes like a takeout upgrade but way more honest.

The garlic parmesan Alfredo sauce makes every layer feel outrageously rich without pretending to be fancy. And the thinly sliced zucchini keeps it bright and not just cloying cheese soup.

I call it my Homemade Vegetable Lasagna because it’s forgiving, freezer-friendly, and actually feeds real life leftovers. Lasagna With Zucchini?

Yes please. It’s the kind of dinner that disappears fast, makes people pause mid-bite, and proves veggies can headline without whining.

Seriously, make it and brag. Please.

9 lasagna noodles, regular or no boil

1 tablespoon olive oil

1 small yellow onion, finely chopped

2 cloves garlic, minced

2 cups fresh spinach, packed

1 medium zucchini, thinly sliced

1 medium yellow squash, thinly sliced

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 375°F. If using regular lasagna noodles, cook them in salted boiling water until al dente, drain and lay flat on a sheet to stop sticking; if using no boil noodles skip this step.

2. Heat olive oil in a large skillet over medium heat. Add chopped onion and sauté until soft and slightly golden, about 5 minutes, then add minced garlic and cook 30 seconds until fragrant.

3. Add zucchini, yellow squash and carrots to the skillet. Season with 1 teaspoon dried Italian seasoning, 1/4 teaspoon red pepper flakes if using, salt and pepper. Cook until veggies are just tender, about 5 to 7 minutes, then stir in the packed spinach and cook until wilted. Remove from heat and let cool a bit.

4. In a medium bowl combine ricotta cheese, lightly beaten egg, 1/4 cup grated Parmesan, a pinch of salt and pepper. Mix until smooth; this will help the filling set so it doesnt run when baked.

5. Pour the entire 24 ounce jar of garlic parmesan Alfredo sauce into a separate bowl and stir so it’s smooth. Reserve about 1/2 cup of shredded mozzarella and 1/4 cup Parmesan for the top.

6. Assemble the lasagna in a 9×13 inch baking dish: spread about 3/4 cup of Alfredo sauce on the bottom. Layer 3 lasagna noodles over the sauce. Spread half of the ricotta mixture over the noodles, then half of the cooked vegetables, then about 1/2 cup Alfredo, and sprinkle 2/3 cup mozzarella and 1/4 cup Parmesan.

7. Repeat: second layer of 3 noodles, remaining ricotta, remaining vegetables, another 1/2 cup Alfredo, and 2/3 cup mozzarella. Top with final 3 noodles, the remaining Alfredo sauce spread evenly, then the reserved mozzarella and Parmesan.

8. Cover tightly with foil (spray foil with cooking spray or tent so cheese doesnt stick) and bake for 25 minutes. Remove foil and bake another 10 to 15 minutes until cheese is bubbly and lightly golden.

9. Let the lasagna rest at least 10 minutes before slicing so it firms up. Sprinkle chopped fresh parsley or basil over the top before serving if you like.

10. To freeze: cool completely, wrap tightly in foil and freeze up to 3 months. Bake from frozen: remove foil, cover with new foil and bake at 375°F about 60 to 75 minutes until hot through, then uncover and brown cheese 10 minutes.

Equipment Needed

1. Oven (preheat to 375°F)
2. Large pot for boiling noodles
3. Colander to drain noodles
4. Large skillet for sautéing vegetables
5. Cutting board and chef’s knife for chopping and slicing
6. Medium and large mixing bowls (one for ricotta mix, one for sauce)
7. 9×13 inch baking dish
8. Spatula or spoon for spreading layers and a wooden spoon for cooking
9. Measuring cups and spoons
10. Aluminum foil (sprpray with cooking spray or tent so cheese wont stick)

FAQ

Q: Can I use no boil lasagna noodles for this recipe? A: Yes, you can use no boil noodles, just make sure the sauce covers the noodles well so they soften while baking. If using regular noodles, boil them a minute or two less than package directions so they dont turn mushy in the oven.

Q: How do I make this ahead of time or freeze it? A: Assemble the lasagna, cover tightly with foil and refrigerate up to 24 hours before baking. To freeze, wrap it well and freeze for up to 2 months. Bake from frozen at 350 F, covered, for about 60-75 minutes, then uncover and bake until bubbly and golden.

Q: Can I swap or add other vegetables? A: Absolutely, this recipe is flexible. Mushrooms, bell peppers, broccoli or kale work great. Just saute firmer veggies first so they release moisture, otherwise the lasagna can get watery.

Q: Is there a dairy free or lower fat option? A: For dairy free, use a plant-based Alfredo and dairy-free ricotta and mozzarella. For lower fat, choose part-skim ricotta and mozzarella and watch the Parmesan amount, but flavor will be a little different.

Q: How do I prevent a watery lasagna? A: Salt and squeeze watery veggies like zucchini or spinach after salting, or roast/sauté them first to remove excess moisture. Use a thicker sauce if needed and dont over-layer wet ingredients.

Q: How long will leftovers keep and how should I reheat them? A: Leftovers keep 3 to 4 days in the fridge. Reheat slices in the oven at 350 F for 15-20 minutes covered, or microwave in 1 minute bursts until hot. Add a splash of milk if it seems dry while reheating.

Easy Alfredo Sauce Vegetable Lasagna Recipe Substitutions and Variations

1 (24 ounce) jar garlic parmesan Alfredo sauce — swap with a quick homemade sauce: melt 4 tablespoons butter, stir in 4 tablespoons flour, slowly whisk in 2 cups milk until thick, then mix in 1 cup grated Parmesan and a pinch of nutmeg. Tastes fresher and you control the salt.
9 lasagna noodles, regular or no boil — replace with thin zucchini or eggplant slices for a low carb, veggie-forward bake; salt and pat dry to keep it from getting watery.
1 1/2 cups ricotta cheese — use small curd cottage cheese blended smooth or try mascarpone for a richer, silkier layer if you want creamy indulgence.
2 cups shredded mozzarella cheese — swap with shredded provolone or fontina for more flavor and better melting if you like a slightly sharper, nuttier taste.

Pro Tips

– Make the filling less watery: squeeze excess moisture out of cooked zucchini, squash and spinach with a clean kitchen towel or paper towels before mixing with the ricotta. If you skip this you’ll get a soggy lasagna and it won’t set up as nicely.

– Use slightly undercooked regular noodles or room-temp no boil noodles: if the lasagna noodles are totally soft already they’ll fall apart while assembling. Cook regular ones to just al dente and let them cool flat. For no boil, let them warm up to room temp so they don’t suck all the sauce out while baking.

– Temper the egg into the ricotta: whisk a tablespoon of warm Alfredo into the egg first, then stir that into the ricotta. That keeps the egg from scrambling and gives a smoother, creamier filling that holds together when you slice.

– For even browning and less burned cheese, bake covered most of the time then uncover for the last 10 minutes. If the top is browning too fast, loosely tent with foil. Also letting it rest 10 to 15 minutes before cutting is crucial, otherwise it will ooze everywhere.
