Mini Vegan Zucchini Lasagna Bites
Equipment
- 1 Benriner Mandoline Slicer – for thin, even zucchini slices
- 1 Pair Cut-Resistant Gloves – for safe slicing
- 1 Lodge Cast Iron Skillet (12-inch) – for browning ground beef
- 1 Medium Mixing Bowl – for ricotta mixture
- 1 9×13-Inch Casserole Dish – for layering and baking
- 1 Spatula – for easy layering and spreading
Ingredients
- 4 large zucchini sliced lengthwise into thin strips
- 2 pounds ground beef lean or 85/15
- 24 ounces marinara or pasta sauce plus ½ cup reserved separately
- 15 ounces ricotta cheese
- 1 cup grated Parmesan Reggiano cheese
- 1½ cups shredded mozzarella cheese divided
- 1 large egg
- Salt and freshly ground black pepper to taste
- 2 tablespoons chopped fresh parsley
- 2 tablespoons chopped fresh basil plus extra leaves for garnish
Instructions
- Prep and Slice the Zucchini: Preheat your oven to 400°F (200°C). Using a sharp knife or a mandoline slicer, slice the zucchini lengthwise into long, even strips about ⅛ to ¼ inch thick. Place the slices on paper towels and lightly salt them to draw out moisture. Let them sit while you prepare the other ingredients.
- Cook the Meat Sauce: In a large skillet over medium-high heat, brown the ground beef. Break it up into small crumbles as it cooks, stirring frequently. Once the meat is fully browned and no pink remains, stir in the pasta sauce—reserving ½ cup for later—and let the mixture simmer for a few minutes. Remove from heat and set aside.
- Mix the Ricotta Filling: In a medium bowl, combine the ricotta cheese, grated Parmesan, egg, a pinch of salt, and a bit of pepper. Stir until the mixture is creamy and well blended. This will form your cheesy, rich middle layer.
- Start Assembling the Lasagna: Spoon the reserved ½ cup of pasta sauce into the bottom of a 9×13-inch baking dish and spread it out evenly. Layer zucchini slices across the bottom—overlapping slightly or arranging side by side, depending on their width.
- Build the Main Layers: Add half of the ground beef sauce over the zucchini layer and spread it evenly. Dollop and gently spread half of the ricotta mixture on top of the sauce. Sprinkle with ½ cup of mozzarella and a generous pinch of chopped basil and parsley.
- Repeat the Layering: Add another layer of zucchini strips, followed by the remaining meat sauce, the rest of the ricotta mixture, and another ½ cup of mozzarella. Finish with a final layer of zucchini on top.
- Add Final Toppings and Bake: Sprinkle the top layer with the remaining ½ cup of mozzarella and a final pinch of fresh herbs. Bake the lasagna uncovered for 40 to 45 minutes, until the top is golden and bubbling. For a nicely browned top, you can broil it for 2–3 minutes at the end.
- Cool and Serve: Remove from the oven and let the lasagna sit for about 10 minutes before slicing. This helps it set and hold its shape. Garnish with fresh basil leaves just before serving.
Notes
- To Avoid a Watery Lasagna: Lightly salting the zucchini slices helps release excess moisture. You can also pat them dry after slicing or even grill them briefly to reduce water content.
- Choose a Quality Sauce: A rich, flavorful marinara—like Rao’s Homemade—adds depth to the lasagna without needing extra seasoning.
- Make It Ahead: This dish can be assembled up to a day in advance and stored in the fridge before baking. It also freezes beautifully for future meals.
- Optional Protein Swaps: Feel free to substitute ground turkey or chicken for a leaner version without sacrificing taste.
- Cheese Options: Add provolone or fontina for a more indulgent cheese pull or adjust the mozzarella to your preference.
Chef’s Secrets for Perfect Texture
Achieving a lasagna that’s rich and satisfying without turning soggy comes down to proper zucchini prep.
One of the most important steps is drawing out moisture from the zucchini slices.
After slicing them lengthwise—preferably using a mandoline for uniform thickness—lightly salt the slices and let them sit for 10 to 15 minutes.
This helps release excess water that would otherwise seep into the dish during baking.
Blotting or lightly grilling the slices can further reduce moisture for firmer, more structured layers.
Also, don’t skip the step of letting the lasagna rest after baking—this allows the cheese and sauce to set, making cleaner slices and better flavor in every bite.
And while store-bought marinara is convenient, using a well-seasoned, thick sauce (or simmering your own) adds extra depth that ties the entire dish together.
Serving Suggestions for a Balanced Meal
This zucchini lasagna is hearty enough to serve as a standalone main course, but it pairs wonderfully with lighter sides to round out the meal.
A crisp green salad with lemon vinaigrette or balsamic dressing adds brightness that complements the richness of the cheese and beef.
For a low-carb dinner, consider serving it with roasted vegetables like broccoli, cauliflower, or asparagus.
If carbs aren’t a concern, a slice of warm garlic bread or a piece of crusty sourdough makes a delicious addition.
For beverages, a glass of red wine—such as Chianti or Cabernet Sauvignon—enhances the tomato and herb flavors beautifully, while a sparkling water with lemon keeps the meal light and refreshing.
Smart Storage Tips and Reheating Advice
Zucchini lasagna stores well and makes excellent leftovers.
After it cools completely, you can store individual slices or the full dish in an airtight container in the refrigerator for up to 4 days.
To reheat, place a slice on a microwave-safe plate and cover loosely—heat in 30-second bursts until warmed through.
For best texture, reheating in the oven at 350°F (covered with foil) for about 15–20 minutes preserves the structure better than the microwave.
This lasagna also freezes well; wrap portions tightly in foil and place in freezer bags.
When ready to eat, thaw overnight in the fridge and reheat in the oven.
It’s a great make-ahead option for busy weeks or meal prepping.
