• It’s vegetarian, but feels indulgent and hearty
• Uses wholesome ingredients like zucchini and spinach
• Can be made gluten-free and dairy-free
• Great for meal prep or freezing ahead
• Family-friendly and crowd-pleasing

Ingredients You’ll Need

• Zucchini (2-3 medium, thinly sliced)
• Fresh spinach (6 cups) or frozen spinach (thawed and drained)
• Ricotta cheese or vegan alternative
• Mozzarella cheese
• Parmesan cheese (or nutritional yeast for a vegan version)
• Marinara or tomato sauce (homemade or store-bought)
• Lasagna noodles (regular, gluten-free, or oven-ready)
• Olive oil, garlic, Italian seasoning, salt & pepper

Optional Add-ins:

• Sliced mushrooms
• Bell peppers

Health Benefits of the Key Ingredients

• Zucchini: Low in calories and high in fiber, zucchini is a great way to lighten up lasagna while adding texture and nutrition.
• Spinach: Loaded with iron, calcium, and antioxidants, it gives your dish a healthy kick.
• Ricotta or tofu-based cheese: Adds protein and creaminess, which balances the acidity of tomato sauce.

Prepping the Vegetables Like a Pro

To get the best texture, prepare your vegetables properly:

• Slice zucchini thinly using a mandoline or sharp knife
• Sprinkle slices with salt and let sit for 10–15 minutes to draw out excess moisture
• Pat them dry with paper towels before layering
• For spinach, quickly sauté it in olive oil with garlic, or thaw and drain frozen spinach thoroughly

The Sauce & Cheese Combo That Makes It Irresistible

Layering flavors is key to any good lasagna. Use a quality marinara or make a simple homemade version with crushed tomatoes, garlic, basil, and olive oil.

Mix your ricotta or vegan ricotta with:

• Sautéed spinach
• A pinch of nutmeg
• Salt and pepper
• An optional egg for stability (skip this if vegan)

Top it all off with melty mozzarella and parmesan or nutritional yeast for that signature lasagna finish.

Choosing and Preparing the Noodles

You have several options when it comes to noodles:

• Traditional pasta sheets (boil before layering)
• Oven-ready noodles (soak briefly in hot water for best texture)
• Zucchini slices (for a low-carb option)

If you’re going full veggie, you can skip noodles entirely and use only zucchini as your “pasta” layers.

Step-by-Step Assembly Instructions

1. Preheat oven to 375°F (190°C).
2. Spread a layer of marinara on the bottom of your baking dish.
3. Add a layer of noodles (or zucchini).
4. Spoon over the ricotta-spinach mixture.
5. Sprinkle with mozzarella and a little parmesan.
6. Repeat layers until the dish is full, ending with sauce and cheese on top.
7. Cover with foil and bake for 30 minutes.
8. Uncover and bake another 15–20 minutes until golden and bubbling.
9. Let it rest for 10–15 minutes before slicing.
