What You’ll Need (Ingredients)

• 3 large zucchinis (straight and firm for clean slices)
• 1 lb ground beef (85–90% lean)
• 1/2 lb Italian sausage (mild or hot, casings removed)
• 1 small yellow onion, finely diced
• 3 cloves garlic, minced
• 1 can (24–28 oz) low-sugar marinara or tomato basil sauce
• 2 tbsp tomato paste
• 1 tsp crushed red pepper flakes (optional, for heat)
• 1 tsp dried oregano
• 1 tsp dried basil
• Salt and black pepper, to taste
• 1 cup whole-milk ricotta
• 1 large egg
• 1/2 cup grated Parmesan, divided
• 2 cups shredded mozzarella
• 2 tbsp olive oil
• Fresh basil, torn, for garnish (optional)

How to Make It – Instructions

1. Prep the zucchini “noodles”: Trim ends and slice lengthwise into 1/8–1/4-inch planks using a mandoline or sharp knife.

   Lay on sheet trays, sprinkle with salt, and let sit 20 minutes to draw out moisture.

2. Par-bake the zucchini: Pat dry, brush lightly with olive oil, and bake at 400°F (200°C) for 8–10 minutes per tray until pliable. This prevents watery lasagna. Set aside to cool.
3. Brown the meats: Heat a large skillet over medium-high.

   Add beef and sausage, breaking into crumbles. Cook until browned with crispy edges. Drain excess fat, leaving about 1 tablespoon.

4. Build the sauce: Add onion and cook until translucent, 3–4 minutes.

   Stir in garlic for 30 seconds. Mix in tomato paste, marinara, oregano, basil, red pepper flakes, and a pinch of salt and pepper. Simmer 10–12 minutes, uncovered, until thick and glossy.

5. Make the ricotta layer: In a bowl, combine ricotta, egg, 1/4 cup Parmesan, a pinch of salt, and pepper.

   Stir until smooth.

6. Assemble: In a 9×13-inch baking dish, spread a thin layer of sauce. Add a tight layer of zucchini planks (overlap slightly), then dollops of ricotta mixture, spread lightly. Sprinkle mozzarella and a bit of Parmesan.

   Repeat layers: sauce, zucchini, ricotta, cheeses—ending with sauce and a final blanket of mozzarella and remaining Parmesan.

7. Bake: Cover loosely with foil (tent it so cheese doesn’t stick). Bake at 375°F (190°C) for 25 minutes. Remove foil and bake 15–20 more minutes until bubbling with golden-brown spots.
8. Rest: Let it stand 15–20 minutes before slicing.

   Yes, waiting is hard. Yes, it’s worth it for clean cuts.

9. Garnish and serve: Top with torn basil and a grind of black pepper. Slice and serve like a pro.

Preservation Guide

• Fridge: Store slices in airtight containers up to 4 days.

  Reheat at 350°F (175°C) for 12–15 minutes or microwave in short bursts.

• Freezer (unbaked): Assemble in a freezer-safe dish, wrap tightly, and freeze up to 2 months. Bake from frozen at 350°F (175°C) covered for 45–55 minutes, then uncover 15 minutes to brown.
• Freezer (baked): Cool completely, portion into slices, wrap, and freeze up to 2 months. Reheat covered at 350°F (175°C) for 20–25 minutes.
• Moisture control tip: Place a paper towel under the lid when storing to catch condensation.

  Remove before reheating.

What’s Great About This

• Gluten-free by design: No noodles, no problem.
• High-flavor payoff: Sausage plus herbs equals “who needs pasta?” energy.
• Macros you can manage: Lower carbs, higher protein and fat keep you satisfied.
• Customizable: Swap cheeses, tweak spice, or go veggie without losing the plot.
• Company-worthy: Slices neatly and looks impressive. You’ll get the “recipe pls” texts.

Avoid These Mistakes

• Skipping the salting step: Zucchini holds water like a sponge. Salting and par-baking prevent a watery pool at the bottom—non-negotiable.
• Too much sauce: More sauce seems fun until your lasagna turns soupy.

  Aim for a medium-thick layer each time.

• Overcooking the zucchini: You want pliable, not mushy. Overbaking leads to a collapse when slicing.
• Cutting too soon: Resting time sets the layers. If you rush, it slides like a landslide—impressive, but messy.
• Skimping on seasoning: Veg works best with bold flavors.

  Taste your sauce and ricotta mixture; adjust salt and herbs.

Different Ways to Make This

• All-veggie version: Skip the meat and sauté mushrooms and spinach with garlic. Add a pinch of nutmeg to the ricotta—chef’s kiss.
• Turkey or chicken swap: Use ground turkey or chicken and boost umami with a splash of Worcestershire or soy/coconut aminos.
• White lasagna: Use a low-carb Alfredo or creamy garlic sauce instead of marinara. Add shredded rotisserie chicken and spinach.
• Extra-cheesy: Add provolone slices between layers for a stretchy, pizzeria vibe.
• Spice lover’s upgrade: Go hot Italian sausage, double the red pepper flakes, and finish with Calabrian chili oil.

  FYI: addictive.

• Herb-forward: Fold chopped fresh basil and parsley into the ricotta for brighter flavor.

FAQ

Do I need a mandoline to slice the zucchini?

No, but it helps for even thickness. A sharp chef’s knife works fine—just aim for consistent planks so the layers cook evenly.

How do I keep it from getting watery?

Salt the zucchini, let it sit, pat dry, and par-bake. Also, simmer the sauce until thick and avoid overloading each layer.

Rest after baking—this is the secret sauce, IMO.

Can I make this dairy-free?

Yes. Use dairy-free ricotta and mozzarella alternatives and check your marinara label. Add nutritional yeast to boost cheesy vibes.

What’s the best marinara to use?

Choose a low-sugar sauce with clean ingredients.

If you’ve got time, simmer crushed tomatoes with garlic, olive oil, basil, and salt for 20 minutes—simple and stellar.

Can I assemble it ahead?

Absolutely. Assemble up to 24 hours ahead, cover, and refrigerate. Add 10–15 minutes to the baking time if it goes in cold.

How many carbs per serving?

Exact numbers vary by sauce and cheese brands, but it typically lands around 6–10 net carbs per serving.

Check labels and calculate if you’re tracking closely.

Will the zucchini taste raw?

Nope. The par-bake plus final bake softens it to a tender, noodle-like texture with a slight bite. It’s pleasant, not crunchy.

Can I add eggs directly to the sauce?

Skip that experiment.

Keep the egg in the ricotta mixture—it helps set the structure without scrambling in your sauce. Trust the process.
