🥒🧀 Healthy Keto & Carnivore Zucchini Lasagna
Lasagna has always been one of my favorite comfort meals, but after switching to a lower-carb way of eating, I wanted a version that still had all the cheesy, hearty goodness without the pasta. A close friend who follows a carnivore diet suggested using thin zucchini slices instead of noodles, and I was surprised by how well they worked. The zucchini becomes tender, the layers stay rich and satisfying, and you still get that classic lasagna experience.
Last weekend, I made this for my family on a cozy Sunday evening. As it baked, the smell of garlic, herbs, seasoned beef, and bubbling cheese filled the kitchen. Even those who normally insist on traditional pasta didn’t miss it. The leftovers tasted even better the next day, making this recipe perfect for meal prep as well.
Whether you’re following keto, low-carb, or a carnivore-friendly lifestyle that includes dairy and small amounts of low-carb vegetables, this lasagna is a delicious way to enjoy comfort food while staying on track.

Paper towels
👩🍳 Instructions
Step 1: Prepare the Zucchini
Slice the zucchini lengthwise.
Sprinkle lightly with salt and let sit for 20 minutes.
Pat completely dry with paper towels.
For even better texture, grill or roast the zucchini slices for 5 minutes before assembling.
Step 2: Cook the Beef
Heat butter or beef tallow in a large skillet.
Brown the ground beef until fully cooked.
Drain excess grease if desired.
Season with salt, pepper, garlic, and Italian seasoning if using.
If making the keto version, stir in the sugar-free marinara and simmer for 5 minutes.
Step 3: Mix the Cheese Filling
Combine:
Ricotta
Cream cheese
Egg
Parmesan
Mix until smooth.
Step 4: Assemble
Lightly grease the baking dish.
Layer:
Meat sauce
Zucchini
Cheese mixture
Mozzarella
Repeat until all ingredients are used.
Finish with mozzarella and Parmesan.
Step 5: Bake
Bake at 375°F (190°C) for 40–45 minutes until bubbly and golden.
Broil for 2–3 minutes for a beautifully browned cheese topping.
Step 6: Rest
Allow the lasagna to rest for 10–15 minutes before slicing.
This helps the layers stay together.
Serve warm.
💡 Tips for Success
Remove Moisture
Salting the zucchini is the secret to preventing watery lasagna.
Fresh Cheese Melts Better

The lasagna slices much more neatly after resting.

❓ Frequently Asked Questions
Is zucchini allowed on a carnivore diet?
Strict carnivore diets exclude vegetables. However, many people following an animal-based or carnivore-friendly approach include small amounts of low-carb vegetables like zucchini. If you follow a strict carnivore diet, simply omit the zucchini and make the layered beef-and-cheese version.
Can I use cottage cheese instead of ricotta?
Yes. Full-fat cottage cheese is an excellent substitute and adds extra protein.
Why is my zucchini lasagna watery?
Zucchini contains a lot of water. Salting it, patting it dry, and briefly roasting or grilling the slices before layering helps remove excess moisture.
Can I prepare it ahead of time?
Absolutely. Assemble the lasagna up to a day in advance, cover, and refrigerate. Bake when ready to serve.
Can I freeze it?
Yes. Cool completely, wrap tightly, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
What cheese works best?
Mozzarella provides the classic stretchy texture, Parmesan adds savory depth, and cream cheese and ricotta create a rich, creamy filling.
