Step-by-Step Instructions for Zucchini Lasagna

Step 1: Prepare the Homemade Tomato Sauce

1. Dice the Tomatoes and Onions: Start by chopping the tomatoes and onions into small pieces.
2. Cook the Onions: In a saucepan, heat 2 tablespoons of olive oil over medium heat. Add the onions and sauté for about 4 minutes until they become soft and translucent.
3. Simmer the Sauce: Add the diced tomatoes, water, fresh basil, salt, and pepper to the pan. Stir everything together, lower the heat, and let the sauce simmer for 35 minutes. The sauce should thicken and develop rich flavors.

Step 2: Prepare the Zucchini

1. Slice the Zucchini: Cut the zucchini into thin strips lengthwise, similar to lasagna noodles. No need to peel the zucchini – the skin is tender and adds a nice texture to the dish.
2. Optional – Salt the Zucchini: If you’re concerned about excess moisture, sprinkle the zucchini strips with salt and let them sit for 10-15 minutes to draw out some of the water. Pat them dry before using.

Step 3: Assemble the Lasagna

1. Prepare the Baking Dish: Preheat the oven to 360°F (180°C). Lightly grease a deep-dish casserole or lasagna pan with olive oil.
2. Layer the Ingredients:
   • Start by placing a thin layer of zucchini slices at the bottom of the pan.
   • Add a spoonful of your homemade tomato sauce on top of the zucchini, followed by a handful of shredded mozzarella and ricotta cheese.
   • Add a few carrot slices for extra flavor and texture.
   • Repeat the layering process until you’ve used up all the ingredients (3-4 layers).
3. Top the Lasagna: Finish with a final layer of sauce and a generous sprinkle of mozzarella and Parmesan cheese.

Step 4: Bake the Lasagna

1. Bake for 35 Minutes: Place the lasagna in the oven and bake for about 35 minutes, or until the cheese is bubbly and golden.
2. Let it Rest: Once out of the oven, let the lasagna rest uncovered for 15-20 minutes to allow the flavors to settle and the dish to firm up.

How to Store and Reheat Zucchini Lasagna

• Storing Leftovers: Allow the lasagna to cool completely before storing it in an airtight container. It will stay fresh in the fridge for up to 3 days.
• Freezing: This lasagna can be frozen! Wrap it tightly in plastic wrap and foil, and freeze for up to 3 months.
• Reheating: To reheat, simply microwave individual servings or bake in the oven at 350°F (175°C) for 20-25 minutes, until hot throughout.

5 Delicious Meal Pairings for Zucchini Lasagna

1. Garlic Bread – A classic pairing that complements the rich flavors of the lasagna.
2. Mixed Green Salad – A light, fresh salad with a lemon vinaigrette balances the hearty lasagna.
3. Grilled Veggies – Roasted or grilled vegetables like bell peppers, asparagus, or eggplant are perfect side dishes.
4. Cauliflower Rice – If you’re looking for a low-carb side, cauliflower rice adds a nice texture without the extra carbs.
5. Sautéed Spinach or Kale – A healthy, savory side that’s packed with nutrients.

Frequently Asked Questions (FAQs)

1. Can I make zucchini lasagna ahead of time?
Yes! You can assemble the lasagna a day ahead and store it in the fridge. Just bake it when you’re ready to serve.

2. How can I make this dish dairy-free?
To make this zucchini lasagna dairy-free, use a plant-based ricotta and mozzarella cheese, and omit the Parmesan.

3. Can I use store-bought tomato sauce instead of making my own?
Absolutely! If you’re short on time, store-bought tomato sauce can be used, but make sure to choose a high-quality brand without added sugars.

Additional Tips & Recommendations

1. Use Thin Zucchini Slices: Thin slices of zucchini cook faster and create less moisture. A mandoline slicer works great for uniform slices!
2. Mix in Extra Veggies: Consider adding spinach, mushrooms, or bell peppers for more texture and flavor.
3. Resting the Lasagna: Allow the lasagna to rest after baking to help it set and make it easier to slice.
