Ingredients You’ll Need
Let’s get our mise en place ready. You’ll need ingredients for three main components: the zucchini “noodles,” the meat sauce, and the cheese filling.
For the Zucchini Layers:
- 4 medium zucchini (about 2 lbs)
- 1 tablespoon olive oil
- Salt and pepper to taste
For the Meat Sauce:
- 1 tablespoon olive oil
- 1 pound ground beef (or a mix of beef and Italian sausage)
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 (28 ounce) can crushed tomatoes (check for no added sugar!)
- 1 teaspoon dried oregano
- 1/2 teaspoon dried basil
- Salt and black pepper to taste
For the Cheesy Filling:
- 15 ounces whole milk ricotta cheese
- 1 large egg
- 1/2 cup grated Parmesan cheese
- 1/4 cup chopped fresh parsley (optional, but recommended!)
- Salt and pepper
For Topping:
- 2 cups shredded whole milk mozzarella cheese
Step-by-Step Assembly Instructions
Making keto lasagna is essentially layering three amazing things together! Follow these steps closely, especially the zucchini prep, for the best results.
Step 1: Prep the Zucchini (Crucial Step!)
This is the most important step to avoid a watery lasagna.
1. Trim the ends off the zucchini. Using a mandoline slicer (carefully!) or a very sharp knife, slice the zucchini lengthwise into thin sheets, about 1/8 inch thick.
2. Lay the slices on paper towels, lightly sprinkle with salt, and let them sit for 15 minutes. The salt draws out moisture.
3. Pat them very dry with fresh paper towels. This step is your insurance against sogginess!
4. Optional but recommended: Lightly brush the slices with olive oil and quickly pan-sear them for 1 minute per side until slightly softened, or bake them on a sheet pan at 375°F (190°C) for 5 minutes.
Step 2: Make the Rich Meat Sauce
1. Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the ground meat and onion. Cook until the meat is browned and the onion is soft. Drain off any excess grease.
2. Stir in the minced garlic and cook for 1 minute until fragrant.
3. Pour in the crushed tomatoes, oregano, and basil. Season generously with salt and pepper. Bring to a simmer, then reduce heat to low, cover, and let it cook for at least 15 minutes while you prepare the cheese filling.
Step 3: Prepare the Ricotta Filling
1. In a medium bowl, combine the ricotta cheese, egg, Parmesan cheese, parsley, salt, and pepper. Mix well until everything is fully incorporated. The egg helps bind the cheese layers together so they don’t ooze out when sliced.
Step 4: Layer and Bake!
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
1. First Layer (Sauce): Spread a thin layer of meat sauce on the bottom of the prepared dish—just enough to cover the bottom.
2. Second Layer (Zucchini): Arrange a single layer of your dried zucchini slices over the sauce, slightly overlapping them if necessary.
3. Third Layer (Ricotta): Dollop half of the ricotta mixture evenly over the zucchini layer and gently spread it out.
4. Fourth Layer (Meat & Mozzarella): Spread about one-third of the remaining meat sauce over the ricotta, then sprinkle with one-third of the mozzarella cheese.
5. Repeat: Start the layering process again: Zucchini, remaining Ricotta, half the remaining Meat Sauce, and another third of the Mozzarella.
6. Final Top: Finish with a final layer of Zucchini, the rest of the Meat Sauce, and top generously with the remaining Mozzarella cheese.
Step 5: Bake to Perfection
1. Cover the baking dish tightly with foil. Bake for 30 minutes.
2. Remove the foil and bake for another 10-15 minutes, or until the cheese is golden brown and bubbly.
3. Crucial Wait Time: Let the lasagna rest on the counter for at least 15 minutes before slicing. This allows the layers to set up properly!
Serving Suggestions
This Keto Lasagna is hearty enough to stand on its own, but I love serving it with something green and fresh to cut through the richness.
- A large, simple Caesar salad (ensure your dressing is sugar-free!).
- Garlic butter sautéed green beans or asparagus.
- A side of crusty, low-carb keto bread, perfect for scooping up extra sauce!
Tips for Customization and Variations
Want to mix things up? I love experimenting!
- Make it Veggie-Forward: Swap half the ground meat for sautéed mushrooms or finely chopped eggplant.
- Spice it Up: Add a pinch of red pepper flakes to the meat sauce for a little kick.
- Go Eggplant: If you aren’t a fan of zucchini, you can use thinly sliced, salted, and drained eggplant rounds instead.
- Béchamel Boost (Advanced): For an extra creamy layer, you can replace the ricotta layer with a keto-friendly Béchamel sauce made with heavy cream and xanthan gum as a thickener.

Frequently Asked Questions (FAQs) About Keto Lasagna
Q1: Why is my keto lasagna watery?
This almost always comes down to not properly removing the moisture from the zucchini. You must salt and drain the zucchini slices first, and pat them thoroughly dry before layering them into the dish. If you skip this, the water they release during baking will turn your lasagna soupy.
Q2: Can I use a different vegetable instead of zucchini?
Yes! Eggplant works wonderfully, though it also needs salting and resting. Some people also use very thin slices of steamed butternut squash if they are in a less strict keto phase or are aiming for a higher vegetable intake, but butternut squash is higher in carbs.
Q3: How far ahead of time can I assemble this?
You can assemble the entire lasagna (without baking) up to 24 hours in advance. Cover it tightly with plastic wrap and refrigerate. Add about 10-15 minutes to the covered baking time if baking straight from the fridge.
Q4: Can I freeze leftover keto lasagna?
Absolutely! Let the baked lasagna cool completely. Cut it into individual portions or leave it whole, cover tightly with plastic wrap, and then wrap in aluminum foil. Freeze for up to 3 months. Thaw overnight in the fridge and reheat covered at 350°F (175°C) until heated through.
