What Ingredients You Will Need

This creamy keto lasagna with zucchini noodles uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and a few fresh additions make it pop.

• Zucchini – 4 medium zucchinis, sliced lengthwise into thin noodles (preferably with a mandoline for even thickness)
• Ground beef – 1 pound (450 g), preferably 85% lean for good flavor and moisture
• Olive oil – 2 tablespoons, for sautéing
• Garlic – 3 cloves, minced (adds aromatic depth)
• Canned crushed tomatoes – 1 can (14 oz/400 g), choose a brand with no added sugar
• Tomato paste – 2 tablespoons, for richness
• Dried Italian herbs – 1 teaspoon (oregano, basil, and thyme blend works well)
• Ricotta cheese – 1 cup (240 ml), whole-milk for creaminess
• Cottage cheese – ½ cup (120 ml), use small-curd for best texture
• Shredded mozzarella – 2 cups (200 g), part-skim or whole milk
• Grated Parmesan cheese – ½ cup (50 g), for that sharp finish
• Egg – 1 large, room temperature (helps bind the cheese filling)
• Salt – to taste (don’t forget to salt zucchini noodles to draw out moisture)
• Black pepper – freshly ground, to taste
• Fresh basil or parsley – a handful, chopped (optional, for garnish and freshness)

If you want to mix things up, you can swap ground beef for ground turkey or chicken. For a dairy-free option, try almond ricotta or cashew cheese, though texture and flavor will shift slightly. I tend to stick to whole-milk cheeses because they melt better and make the dish extra creamy.

Equipment Needed

• Mandoline slicer or a sharp knife – for slicing zucchini into thin, even noodles
• Large skillet or sauté pan – to brown the meat and cook the sauce
• Mixing bowls – for combining cheeses and prepping ingredients
• 9×13-inch baking dish (23×33 cm) – standard size for assembling the lasagna layers
• Colander or fine mesh strainer – to drain excess moisture from zucchini noodles after salting
• Wooden spoon or spatula – for stirring sauce and mixing cheese

If you don’t own a mandoline, no worries—just use a sharp knife, but try to keep slices uniform thickness to avoid uneven cooking. For budget-friendly options, a vegetable peeler can also help create long zucchini ribbons.

Preparation Method

1. Prepare the zucchini noodles: Slice the zucchinis lengthwise into thin noodles about ⅛ inch (3 mm) thick using a mandoline or knife. Lay them flat on a large baking sheet or colander, sprinkle generously with salt (about 1 teaspoon), and let them sit for 15-20 minutes to draw out moisture. After resting, gently squeeze the noodles in a clean kitchen towel or paper towels to remove any excess water. This step is crucial to prevent soggy lasagna.
2. Make the meat sauce: Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the minced garlic and sauté for 30 seconds until fragrant. Add the ground beef and cook, breaking it up with a wooden spoon, until browned and cooked through (about 7-8 minutes). Stir in the crushed tomatoes, tomato paste, dried Italian herbs, salt, and pepper. Let the sauce simmer on low heat for 15 minutes, stirring occasionally. If the sauce gets too thick, add a splash of water.
3. Prepare the cheese mixture: In a medium bowl, combine the ricotta cheese, cottage cheese, grated Parmesan, egg, and half of the shredded mozzarella. Mix until smooth and creamy. Season with a pinch of salt and pepper. This blend gives the lasagna that signature creamy texture.
4. Preheat the oven: Set your oven to 375°F (190°C) to get it ready for baking.
5. Assemble the lasagna: Spread a thin layer of meat sauce on the bottom of the baking dish (about ½ cup/120 ml). Layer zucchini noodles evenly over the sauce, overlapping slightly to cover the surface. Spread a generous layer of the cheese mixture over the zucchini, then spoon more meat sauce on top. Repeat these layers—zucchini noodles, cheese mixture, meat sauce—until all ingredients are used, finishing with a layer of shredded mozzarella on top.
6. Bake the lasagna: Cover the baking dish tightly with foil and bake for 25 minutes. Remove the foil and bake uncovered for another 15 minutes or until the cheese on top is bubbly and golden brown. Let the lasagna rest for 10 minutes before slicing—this helps it set and makes serving easier.

Pro tip: If the top browns too quickly, loosely tent with foil to avoid burning. And if you find your zucchini noodles releasing too much moisture during baking, try squeezing out even more water next time or patting them dry well before assembling.

Cooking Tips & Techniques for Success

Honestly, making a creamy keto lasagna with zucchini noodles is pretty straightforward, but a few tricks make all the difference:

• Salting the zucchini noodles: This is key to avoid watery lasagna. Give them a good salt bath and let them sweat for at least 15 minutes, then squeeze out every bit of moisture you can. It’s a little extra work but worth it.
• Choose the right cheese: Whole-milk ricotta and small-curd cottage cheese melt better and create that luscious texture. Avoid low-fat versions—they tend to be watery.
• Use a mandoline slicer: For even zucchini noodles that cook uniformly. Uneven slices lead to some parts undercooked or mushy.
• Don’t skip resting time: Letting the lasagna sit after baking helps it firm up, so it slices cleanly instead of falling apart.
• Cooking the meat sauce low and slow: This lets flavors meld and prevents a watery sauce that can ruin the texture.
• Multitasking tip: While the sauce simmers, prep the zucchini noodles and mix the cheese filling to save time.

I once rushed salting the zucchini and ended up with a soggy mess—lesson learned! Patience is your best friend here.

Variations & Adaptations to Try

Feel free to customize this creamy keto lasagna with zucchini noodles to suit your taste or dietary needs:

• Vegetarian version: Swap the ground beef for sautéed mushrooms, chopped spinach, and diced bell peppers for a veggie-packed twist.
• Spicy kick: Add red pepper flakes or diced jalapeños to the meat sauce for a subtle heat that wakes up the flavors.
• Seasonal substitutions: In summer, swap canned tomatoes for fresh, peeled plum tomatoes for a brighter sauce. Or add fresh basil leaves between the layers for extra aroma.
• Dairy-free option: Use almond or cashew-based ricotta alternatives and vegan mozzarella shreds, though texture will be slightly different.
• Cheese swap: Try mixing in goat cheese or feta for tangy notes that complement the creamy layers.

Personally, I love making the vegetarian version when zucchini is in season and topping it with fresh basil—it feels lighter but still satisfying.

Serving & Storage Suggestions

This creamy keto lasagna with zucchini noodles is best served warm, straight from the oven. Let it rest for 10 minutes so each slice holds its shape beautifully. Garnish with a sprinkle of fresh parsley or basil for a pop of color and freshness.

Pair it with a crisp green salad tossed in a simple vinaigrette or some roasted garlic broccoli for a well-rounded, low-carb meal. A glass of dry red wine or sparkling water with lemon really complements the rich flavors.

To store, cover leftovers tightly with foil or plastic wrap and refrigerate for up to 4 days. You can also freeze individual portions wrapped in foil and stored in freezer bags for up to 3 months. When reheating, microwave covered for 2-3 minutes or warm in a 350°F (175°C) oven until heated through. The flavors actually deepen over time, making leftovers even tastier!

Can I make this recipe ahead of time?

Yes! You can assemble the lasagna the night before, cover it tightly, and bake it fresh the next day. Just add a few extra minutes to the baking time if refrigerated.
