This velvety garden veggie lasagna with Alfredo brings everyday vegetables to life as a fancy dinner guests will adore. Layers of soft squash, zucchini, carrots and spinach blend into a colorful meat-free meal that'll win over even the biggest carnivores.
I whipped this up when my veggie-loving niece stopped by, and it was such a smash hit that we now make it all the time. The smooth sauce mixed with fresh garden goodies makes everyone forget they're eating something that's actually good for them.
Ingredients
- Lasagna noodles: they create the perfect layers. The oven-ready ones cut down on prep time
- Yellow squash and zucchini: they bring juiciness without making things soggy
- Carrots: they add a touch of natural sweetness and pretty orange color
- Fresh spinach leaves: they pack in nutrients with a mild earthy taste
- Jarred Alfredo sauce: it makes everything easier while adding creamy richness
- Ricotta cheese: it gives that wonderful comfort food texture
- Mozzarella cheese: it creates that must-have gooey pull when served
- Cheddar cheese: it brings a nice tangy kick
- Italian seasoning: it ties all the flavors together beautifully
Cooking Guide
- Ready Your Noodles:
- If you're using regular noodles, boil them until they're just firm to the bite. Skip this step for oven-ready varieties. Get your oven warming to 350°F while you sort out the other stuff.
- Start Your Foundation:
- Put a small amount of Alfredo sauce on the bottom of a deep 9x12 inch baking dish. This stops sticking and starts building taste from the ground up.
- Begin With Veggies:
- Put zucchini pieces in one layer over the sauce. Try to fill in all the gaps. Drop spoonfuls of ricotta evenly on the zucchini, then scatter some mozzarella on top. Sprinkle a bit of salt, pepper, and Italian herbs.
- Layer In Pasta:
- Put lasagna noodles on next, letting them overlap slightly to make a solid base for what comes next.
- Keep Building Up:
- Do the same with yellow squash, spinach, and carrots, making separate layers. For each veggie layer, add Alfredo, ricotta, mozzarella, and noodles. Make sure everything's spread out nicely so every bite tastes good.
- Top It Off:
- After your last noodle layer, spread whatever Alfredo sauce is left so all noodles are covered completely. This helps them cook right without drying out. Finish with leftover mozzarella and a sprinkle of cheddar for a golden top.
- Cook It Right:
- Cover with foil and bake for 25 minutes. Take the foil off and cook another 10 to 15 minutes until the cheese bubbles and edges turn golden. Let it sit for 10 minutes before cutting so the layers don't fall apart.

I learned the trick of arranging veggies by thickness during a cooking class I took in Florence. Starting with zucchini at the bottom lets its moisture come out gradually, while saving the harder carrots for upper layers makes sure everything gets done at the same time. My kids especially love the sweet bits that carrots add to every forkful.
Prep Ahead and Keeping Leftovers
This veggie lasagna works great for planning ahead. Put it all together, wrap it tight with plastic and foil, and keep it in the fridge up to 2 days before cooking. Just add about 15 extra minutes to cooking time if it's cold from the fridge.
Any leftovers stay good in the fridge for about 4 days. You can freeze single portions for up to 3 months. Let them thaw in the fridge overnight before warming them up for the best taste.

Mix Up Your Veggies
The best thing about this dish is how easy it is to swap things around. In summer, try thin slices of eggplant or bell peppers. During fall, butternut squash adds a sweet nutty flavor. Fresh mushrooms give a rich earthiness that goes really well with the creamy sauce.
To make it even healthier, throw in some chopped kale with the spinach or add a layer of roasted cauliflower. Just remember to cut all veggies nice and thin so they cook evenly and share their flavors with the sauce.
What to Serve With It
This lasagna goes great with a simple arugula salad topped with lemon and olive oil to balance out the richness. Add some garlic bread on the side to soak up extra sauce.
When you have friends over, try making personal portions in small dishes for a fancy touch. Top with fresh basil and a light sprinkle of good Parmesan right before bringing them to the table.
