Healthy and super delicious, this easy one skillet meal can be prepared AND cooked in less time than it takes to do just the prep work for a traditional baked lasagna.
On the table in just 30 minutes, my easy vegetable skillet lasagna is loaded with zucchini, yellow squash, onions, and mushrooms in a zesty and cheesy tomato sauce.

Easy Vegetable Skillet Lasagna: behind the recipe
The idea of a healthy vegetable lasagna wasn’t at the top of my husband’s dinner wishlist, but after trying my easy zucchini skillet lasagna he had to admit a no-meat lasagna was actually pretty good. Now, that’s saying a lot coming from my John!
He thinks a meal without meat is just a snack. You know, he’s a meat-and-potatoes kind of guy.
Sometimes, though, it’s good to mix things up. Even for a guy that’s normally not a zucchini fan.
“Try it, you’ll like it,” I say.
“Not bad,” he says as he takes another bite. I’ll take that as a thumbs up!
With squash plentiful this time of year, I like finding new recipes that let zucchini shine. Here’s what you’ll need for this fresh and healthy skillet lasagna:
- Zucchini — one medium-size (about 6 to 8 inches)
- Yellow squash — one medium-size (about 6 to 8 inches)
- Mushrooms — one 8-ounce package
- Oven-ready lasagna noodles — It’s very important to get the ones that don’t need to be cooked first!
- Diced tomatoes — I use the petite-diced canned tomatoes canned.
- Tomato paste — adds body to the sauce
- Garlic — fresh or jarred minced
- Oregano — dried or fresh
- Ricotta cheese
- Mozzarella cheese — thin slices
- Parmesan cheese
- Italian flat-leaf parsley
How to make zucchini skillet lasagna
STEP 1: Sauté the veggies
- Use a deep 12-inch skillet so you have plenty of room. I like to use my cast iron because it looks nice for serving at the table.
- Add the garlic (adds so much flavor!), diced tomatoes and tomato paste, then simmer with the vegetables for 5 minutes.
STEP 2: Add cheese and noodles
- Add ricotta cheese by the spoonfuls directly into the simmering sauce.
- Break the lasagna noodles in half and nestle into the sauce and cover with thin mozzarella cheese slices.
- Be sure to use the no-cook or oven-ready lasagna noodles that don’t have to be cooked ahead of time for this recipe. They are perfect since they help soak up water from the zucchini resulting in the perfect sauce to noddle ratio.
STEP 3: Simmer
- Top with a lid and cook just 15 minutes, until the noodles are tender and the cheese is all melty.
- Serve directly from the skillet garnished with Parmesan cheese and chopped fresh Italian parsley.
Frequently asked questions
Don’t overcook the lasagna, because doing so releases too much liquid. In this recipe, sauté the vegetables for just 5 minutes before adding the remaining lasagna ingredients.
Also, it’s important to use the no-cook/oven-ready type of dried lasagna noodles which absorb liquid as they cook.
Always up for debate, the number of lasagna layers can vary. In a baked lasagna, most pans will hold three layers, but I prefer to keep it at two for a saucier lasagna. This skillet lasagna only uses one layer of lasagna noodles, but is still hearty and satisfying.
For baked lasagnas, start with a thin layer of sauce, then noodles, the cheese mixture, more sauce, and repeat. Cover the top layer with mozzarella cheese.
For skillet lasagna, make wells in the sauce on the bottom, fill the wells with spoons of ricotta cheese, then lay noodles on top and cover with a little sauce and mozzarella cheese slices.
A nice tossed salad and a loaf crusty French bread are always good options for completing a lasagna dinner. We especially like spreading roasted garlic butter on our bread! Other delicious salad options include:
- Caprese Salad
- Chopped Italian Salad
- And for dessert, easy individual Chocolate Soufflés!

My family loved this one pan zucchini lasagna! I am always looking for ways to use our abundance of garden veggies this time of year and this recipe was great for that. I added in one green bell pepper and used the shredded mozzarella I had on hand instead of sliced. This was my first time using the no-cook lasagna noodles and they turned out perfect. I definitely will be making this recipe again. Thank you Sheila!
Yay! I’m so glad you and the family enjoyed the lasagna recipe!
It’s official: All the members of my family (me included) loved this recipe. No one realized there wasn’t any meat, either, because it was so flavorful! Veggie lasagna for the win!
Skillet meals are my FAV!! This one did not dissapoint! In fact, I think they loved it every bit as much as my time-consuming lasagna recipe! Win for me!
