Healthy Zucchini Lasagna
Equipment
- 1 Mandoline Slicer – for evenly slicing zucchini
- 1 Pair Cut Resistant Gloves – to protect fingers during slicing
- 1 Large Skillet or Frying Pan – for cooking the bolognese sauce
- 1 Medium Mixing Bowl – for the ricotta mixture
- 1 9×13-Inch Casserole Dish – for assembling and baking the lasagna
Ingredients
- 4 large zucchini sliced lengthwise
- 2 pounds ground beef lean
- 24 ounces marinara or pasta sauce divided (reserve ½ cup)
- 15 ounces ricotta cheese
- 1 cup grated Parmesan Reggiano cheese
- 1 ½ cups shredded mozzarella cheese
- 1 large egg
- Salt and black pepper to taste
- 2 tablespoons fresh parsley finely chopped
- 2 tablespoons fresh basil finely chopped
Instructions
- Prepare and Slice the Zucchini: Preheat your oven to 400°F (200°C). Rinse and dry the zucchini, then slice them lengthwise into thin strips using a sharp knife or a mandoline slicer for uniform thickness. Set aside on a paper towel-lined tray to absorb excess moisture.
- Cook the Ground Beef Bolognese: Heat a large skillet over medium-high heat. Add the ground beef, breaking it up into small crumbles with a spatula. Cook until browned and no longer pink, about 7–10 minutes. Drain excess grease if needed. Stir in all but ½ cup of the marinara sauce. Simmer for 2–3 minutes, then remove from heat.
- Make the Creamy Ricotta Blend: In a medium mixing bowl, combine the ricotta cheese, grated Parmesan, and one egg. Season with a pinch of salt and pepper, then mix until smooth and well combined. This creamy layer will add rich texture to your lasagna.
- Layer the Lasagna – First Layers: Spread the reserved ½ cup of marinara sauce evenly across the bottom of a 9×13-inch baking dish. Add the first layer of zucchini slices over the sauce, overlapping slightly if needed to cover the bottom.
- Add Sauce, Cheese, and Herbs: Spoon half of the beef and marinara mixture over the zucchini layer and spread evenly. Dollop and spread half of the ricotta mixture over the meat layer. Sprinkle ½ cup of mozzarella cheese, then finish with a handful of chopped parsley and basil.
- Repeat and Finish the Layers: Repeat the layers one more time: zucchini slices, the remaining beef sauce, the rest of the ricotta mixture, and another ½ cup of mozzarella. For the top layer, add any remaining zucchini and finish with the last ½ cup of mozzarella cheese, along with extra Parmesan if desired.
- Bake Until Golden and Bubbly: Cover the baking dish loosely with foil and bake in the preheated oven for 30 minutes. Then uncover and bake for an additional 15–20 minutes, or until the top is golden and bubbling. Let it rest for 10–15 minutes before slicing. This helps everything set beautifully.
Notes
- Preventing Wateriness: Zucchini contains a lot of moisture. For even better results, sprinkle zucchini slices with a little salt and let them sit for 10–15 minutes before assembling. Pat dry with paper towels to draw out excess water.
- Sauce Tip: A thick, high-quality pasta sauce (like Rao’s) works best and helps prevent a soggy lasagna. Avoid watery sauces.
- Meal Prep Friendly: This dish stores wonderfully in the fridge and makes excellent leftovers. Perfect for meal prepping lunches or dinners ahead of time.
- Make it Lighter: Substitute part of the ricotta with cottage cheese for a slightly lighter version that still holds together well.
- Add Veggie Variety: Add sautéed mushrooms, spinach, or chopped bell peppers to the beef mixture for extra nutrients and flavor.
Chef’s Secrets for Zucchini Lasagna Success
The secret to making a zucchini lasagna that isn’t watery starts with properly preparing the zucchini.
After slicing the zucchini lengthwise, it’s essential to draw out moisture. Lightly salt the slices and let them sit for 10–15 minutes before patting them dry with paper towels—this helps avoid a soggy final dish.
A mandoline slicer ensures uniform slices that cook evenly and layer neatly.
When building the lasagna, use a thick, hearty sauce—homemade or store-bought—to help absorb any residual moisture from the zucchini.
Don’t skip the resting period after baking; allowing the lasagna to sit for 10–15 minutes helps the layers firm up, making slicing easier and cleaner.
For enhanced flavor, don’t underestimate the power of fresh herbs like basil and parsley—they add a vibrant finish and balance the richness of the cheese and beef.
Serving Suggestions to Elevate Your Meal
This zucchini lasagna is a complete meal on its own, but it pairs beautifully with light, fresh sides.
Consider serving it with a crisp garden salad dressed in lemon vinaigrette or a simple arugula salad with shaved Parmesan and pine nuts.
Garlic bread or low-carb almond flour biscuits can be added for a heartier spread.
For a refreshing contrast, try a chilled cucumber or tomato gazpacho in warmer months.
This dish also works well as part of a larger Italian-inspired dinner—pair it with roasted vegetables, olives, or a small antipasto platter.
And don’t forget a glass of red wine like Chianti or a non-alcoholic sparkling drink for the perfect finishing touch.
Smart Storage Tips and Reheating Advice
Leftover zucchini lasagna stores very well and is perfect for meal prep.
Allow the lasagna to cool completely before storing to prevent condensation from making it watery.
Transfer portions into airtight containers and refrigerate for up to 4 days.
For longer storage, wrap individual portions tightly in plastic wrap and place in a freezer-safe container for up to 2 months.
When reheating, microwave individual portions in 1-minute intervals until heated through, or reheat in the oven at 350°F (175°C) for 15–20 minutes, covered loosely with foil.
For best texture, avoid reheating in a high-humidity microwave environment—cover loosely to retain moisture but allow some airflow.
