Why This Recipe Works
- Zucchini slices replace noodles, keeping the structure and layers you love but cutting the carbs dramatically.
- Simple, savory meat sauce made with ground beef, crushed tomatoes, and Italian seasoning brings big flavor fast.
- Ricotta-egg mixture adds a creamy, custard-like layer that sets nicely as it bakes.
- Broiled finish gives you that golden, bubbly cheese top without overcooking the zucchini.
- Meal-prep friendly: It reheats well and keeps its shape better than many noodle-free casseroles.
What You’ll Need
- 2 medium zucchini, ends trimmed (for the “noodles”)
- 1 pound (450 g) ground beef, 85–90% lean
- 1 small onion, finely diced
- 3 cloves garlic, minced
- 1 can (14–15 oz) crushed tomatoes or tomato sauce (no sugar added)
- 2 tablespoons tomato paste
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1/2 teaspoon red pepper flakes (optional, for heat)
- Salt and black pepper, to taste
- 1 tablespoon olive oil
- 1 cup ricotta cheese (whole milk)
- 1 large egg
- 1/2 cup grated Parmesan cheese, divided
- 1 1/2 cups shredded mozzarella
- Fresh parsley or basil, chopped (for garnish, optional)
Step-by-Step Instructions
- Prep the zucchini “noodles.” Using a mandoline or a sharp knife, slice zucchini lengthwise into 1/8–1/4-inch planks. Lightly sprinkle with salt and lay them on paper towels for 10–15 minutes to draw out moisture.
Pat dry thoroughly.
- Optional pre-bake for firmer layers. Arrange zucchini slices on a parchment-lined baking sheet. Bake at 400°F (200°C) for 8–10 minutes to release extra moisture. Pat dry again.
This step prevents a watery casserole.
- Make the meat sauce. Heat olive oil in a large skillet over medium heat. Add onion and cook 3–4 minutes until softened. Stir in garlic for 30 seconds until fragrant.
- Brown the beef. Add ground beef, breaking it up with a spoon.
Cook until no longer pink, about 5–7 minutes. Drain excess fat if needed.
- Simmer with tomatoes and spices. Stir in crushed tomatoes, tomato paste, oregano, basil, red pepper flakes, salt, and pepper. Simmer 8–10 minutes until thickened.
Taste and adjust seasoning.
- Mix the ricotta layer. In a bowl, combine ricotta, egg, and half the Parmesan. Add a pinch of salt and pepper. Stir until smooth.
- Assemble the layers. Lightly oil a 9×9-inch (or similar) baking dish.
Spread a thin layer of meat sauce on the bottom. Add a single layer of zucchini slices, slightly overlapping. Dollop and spread some ricotta mixture, then sprinkle mozzarella.
Repeat layers: sauce, zucchini, ricotta, mozzarella. Finish with sauce and the remaining mozzarella and Parmesan.
- Bake. Cover loosely with foil (tent so cheese doesn’t stick). Bake at 375°F (190°C) for 25 minutes.
Remove foil and bake 10–15 minutes more until bubbly and golden around the edges.
- Optional broil. For a deeper golden top, broil 1–2 minutes, watching closely.
- Rest before slicing. Let it rest 10–15 minutes. This helps it set and slice cleanly.
- Garnish and serve. Top with chopped parsley or basil. Serve warm with a crisp salad or roasted veggies.
How to Store
- Refrigerate: Cool completely, then cover and store for up to 4 days.
Reheat in the oven at 325°F (165°C) until warmed through, or microwave individual slices.
- Freeze: Wrap tightly in two layers (plastic wrap and foil) for up to 2 months. Thaw overnight in the fridge, then reheat at 350°F (175°C) until hot.
- Meal prep tip: Bake in two smaller dishes. Eat one now and freeze the other for later.
Why This Is Good for You
- Lower in carbs: Swapping pasta for zucchini cuts carbs significantly while keeping satisfaction high.
- Protein-rich: Ground beef, ricotta, and mozzarella provide a solid protein boost to keep you full.
- Nutrient-dense: Zucchini adds fiber, potassium, and vitamin C, while tomatoes bring lycopene and antioxidants.
- Balanced fats: Using whole-milk cheeses offers better texture and flavor, and helps with satiety.
What Not to Do
- Don’t skip drying the zucchini. Excess moisture makes the bake soupy.
Salt, pre-bake, and pat dry.
- Don’t over-sauce. Keep layers light. Too much sauce can cause slipping and extra moisture.
- Don’t slice immediately. Let it rest so layers set and flavors settle.
- Don’t under-season. Taste your sauce and ricotta mixture. Zucchini is mild and needs well-seasoned layers.
Alternatives
- Vegetable swaps: Use thin eggplant slices or blanched cabbage leaves instead of zucchini.
- Different proteins: Try Italian sausage, ground turkey, or a beef/sausage blend for extra flavor.
- Dairy-free: Use a dairy-free ricotta and mozzarella alternative.
Add nutritional yeast to the “ricotta” for a cheesy note.
- Keto boost: Add chopped olives or sautéed mushrooms to the meat sauce for more flavor and texture without many carbs.
- Sauce shortcut: Use a no-sugar-added marinara to save time. Simmer with browned beef and spices to deepen flavor.
FAQ
How do I keep the lasagna from being watery?
Pat the zucchini dry after salting, and consider pre-baking the slices. Keep the sauce thick, not runny.
Let the finished lasagna rest before slicing so it sets.
Can I make this ahead?
Yes. Assemble up to a day in advance and refrigerate. Add 10–15 minutes to the bake time if going straight from the fridge, or let it sit at room temperature for 20–30 minutes before baking.
What kind of pan works best?
A 9×9-inch or similar ceramic or glass dish works well.
Metal pans heat faster, so check for doneness a few minutes early to prevent over-browning.
Is this gluten-free?
Yes, as written it’s naturally gluten-free. Always confirm your tomato products and cheese are labeled gluten-free to be safe.
Can I use cottage cheese instead of ricotta?
You can. Blend cottage cheese briefly for a smoother texture, then mix with egg and Parmesan.
It will be slightly lighter but still creamy.
What if I don’t have a mandoline?
Use a sharp chef’s knife and cut carefully. Aim for even slices so they cook at the same rate. Slightly thicker slices may need a longer pre-bake.
How do I prevent the cheese from burning?
Tent the dish with foil for the first part of baking.
Remove the foil to brown at the end, and broil only if needed, watching closely.
Can I add vegetables to the sauce?
Absolutely. Finely chopped mushrooms, spinach, or bell peppers work great. Sauté them with the onions to release moisture before layering.
What’s the best way to reheat leftovers?
Reheat in the oven at 325°F (165°C) until warmed through for the best texture.
For single portions, the microwave is fine; blot any moisture after heating.
How many carbs are in a serving?
Exact numbers vary by brands and portion size, but it’s typically far lower than traditional lasagna. Using zucchini, no-sugar-added tomatoes, and whole-milk cheeses keeps net carbs modest per serving.
