This zucchini lasagna recipe is a lighter, low-carb twist on the classic Italian favorite. Tender zucchini slices replace most of the pasta, layered with a rich, savory tomato and vegetable sauce, creamy cottage cheese, and a blend of mozzarella, cheddar, and Parmesan. To add extra flavor and texture, this version also includes finely diced red bell pepper, shredded carrots, and a touch of sun-dried tomatoes. Baked until golden and bubbly, it’s perfect for weeknight dinners or meal prep, and even picky eaters will love it.
Ingredients:
- 3 (15 oz) cans tomato sauce
- 1 small green bell pepper, diced
- 1 small red bell pepper, roasted and diced
- 1 small onion, diced
- 4 oz mushrooms, diced
- ½ cup shredded carrot
- ¼ cup sun-dried tomatoes, chopped
- 2 cloves garlic, minced
- ½ tsp crushed red pepper flakes (optional)
- 1 tsp dried basil
- 1 tsp dried oregano
- 1 tsp Italian seasoning

- 4 cups zucchini, thinly sliced
- 1 (15 oz) container cottage cheese
- 8 oz shredded mozzarella cheese

- 1 tsp olive oil (optional, to sauté vegetables)
Instructions:
- Prepare the Vegetable Sauce:
- Heat tomato sauce in a medium saucepan over medium heat.
- Add onion, green and red bell peppers, mushrooms, carrot, sun-dried tomatoes, garlic, and crushed red pepper flakes.
- Stir in basil, oregano, Italian seasoning, parsley, salt, and pepper. Simmer 10–12 minutes until vegetables are tender and flavors blend.
- Layer the Lasagna:
- Preheat oven to 350°F (175°C).
- In a greased 9×13-inch baking dish, start with a layer of zucchini slices (or zucchini + noodles).
- Spread ½ of the vegetable sauce over the zucchini.
- Layer half of the cottage cheese, half of the mozzarella, half of the cheddar, and sprinkle 1 oz of crumbled feta.
- Repeat with remaining zucchini, sauce, cheeses, and feta.
- Bake:
- Cover with foil and bake 50–60 minutes.
- Remove foil and bake another 20 minutes until top is golden and bubbly.
- Let rest 10–15 minutes before slicing to allow layers to set.
- Serve:
- Garnish with fresh basil or parsley. Serve warm as a main dish or with a side salad.
Optional Tips & Variations:
- Swap cheddar for fontina or gouda for a richer cheesy flavor.
- Add fresh spinach or kale between layers for extra greens.
- For a vegan version, substitute cottage cheese with ricotta-style tofu and mozzarella with vegan cheese.
