17 Keto Lasagna Recipes Without the Carbs

Missing lasagna on your keto journey? You don’t have to sacrifice this comfort food classic anymore. These creative low-carb versions use everything from vegetables to deli meat as noodle replacements, delivering all the cheesy, saucy satisfaction you crave without the carb overload.

Whether you’re a keto veteran or just starting out, these recipes prove that eating low-carb doesn’t mean giving up your favorite Italian dishes. Each variation offers its own unique twist while keeping you firmly in ketosis, and many can be prepped ahead for easy weeknight dinners.

Classic Keto Zucchini Lasagna

Thinly sliced zucchini strips replace traditional pasta, soaking up all that delicious sauce while staying tender. The zucchini adds a subtle sweetness and moisture that actually enhances the classic lasagna flavors. You’ll want to salt and drain the zucchini first to prevent a watery dish, but that extra step is worth it.

The layers hold together beautifully when you slice it, and most people honestly can’t tell they’re not eating regular noodles. This is the gateway recipe for anyone new to keto lasagna.

Keto Eggplant Lasagna

Roasted eggplant slices create a heartier, more substantial noodle replacement than zucchini. The eggplant takes on a meaty texture that pairs perfectly with rich tomato sauce and gooey cheese. Pre-roasting the eggplant removes excess moisture and concentrates the flavor wonderfully.

This version feels more like traditional lasagna in terms of texture and heft. It’s ideal for those who want something that really sticks to your ribs.

Keto Cabbage Lasagna

Cabbage leaves might sound unusual, but they work surprisingly well as lasagna layers. They soften during baking and become almost noodle-like while adding a subtle sweetness. The cabbage is incredibly budget-friendly compared to other low-carb options, making this perfect for feeding a crowd.

It holds up well structurally and doesn’t release as much water as zucchini. This is a game-changer for anyone watching both carbs and their wallet.

Keto Chicken Alfredo Lasagna

Creamy Alfredo sauce replaces marinara in this white lasagna variation that’s pure indulgence. Tender chicken pieces add protein and make this a complete meal in one dish. The rich, garlicky sauce coats every layer of whatever noodle replacement you choose—zucchini or eggplant both work great.

This feels decadent enough for special occasions but comes together easily for weeknight dinners. It’s perfect for anyone tired of tomato-based dishes.

Keto Meatball Lasagna

Mini meatballs nestled between layers create pockets of savory, seasoned meat throughout. This takes lasagna to the next level by adding extra protein and flavor in every bite. The meatballs stay moist during baking thanks to all that cheese and sauce surrounding them.

You can use store-bought meatballs to save time or make your own for better carb control. Kids especially love discovering the meatballs hidden in each slice.

Keto White Lasagna

This elegant variation skips the red sauce entirely, focusing on creamy béchamel and ricotta layers. The flavor is milder and more delicate than traditional lasagna, with garlic and Italian herbs doing the heavy lifting. It’s perfect for those who find marinara too acidic or simply want something different.

The all-white layers look sophisticated when sliced and served. This is your go-to for impressing dinner guests while staying keto.

Keto Spinach and Ricotta Lasagna

Loads of spinach mixed into creamy ricotta creates a vegetarian-friendly option that doesn’t skimp on flavor. The spinach adds nutrients, color, and a subtle earthiness that balances the rich cheese beautifully. This version feels lighter than meat-heavy lasagnas while still being completely satisfying.

You can use fresh or frozen spinach, making it convenient year-round. It’s an excellent way to sneak more greens into your diet.

Keto Mexican Lasagna

Taco-seasoned ground beef, salsa, and Mexican cheese blend transform lasagna into a fiesta. This fusion dish uses low-carb tortillas, cheese slices, or even zucchini as the layers. The flavors are bold and spicy, completely different from Italian-style lasagna but equally craveable.

Top it with sour cream, avocado, and cilantro for the full experience. It’s perfect for taco Tuesday or anytime you want something with a kick.

Keto Sausage Lasagna

Italian sausage brings extra flavor and fat content that makes this incredibly satisfying. The sausage seasons the entire dish as it cooks, infusing every layer with its spices. You can use mild or spicy sausage depending on your preference, making it customizable.

The higher fat content from the sausage helps you hit your keto macros effortlessly. This is comfort food at its finest.

Keto Lasagna with Palmini Noodles

Palmini noodles made from hearts of palm are the closest thing to real pasta in texture and appearance. They’re neutral in flavor, so they let the sauce and cheese shine without adding any veggie taste. These noodles require minimal prep—just rinse and layer—making assembly super quick.

The texture holds up beautifully during baking without getting mushy. This is perfect for keto purists who want the most authentic lasagna experience possible.

Keto Mushroom Lasagna

Earthy mushrooms sautéed with garlic create umami-rich layers throughout this vegetarian option. The mushrooms add a meaty texture without any actual meat, satisfying even committed carnivores. This version works beautifully with either red or white sauce, depending on your mood.

The mushrooms release moisture during cooking, so pre-cooking them is essential. It’s an elegant, sophisticated take that feels restaurant-quality.

Keto Bolognese Lasagna

Rich, slow-simmered meat sauce makes this the most traditional-tasting keto lasagna possible. The Bolognese is packed with ground beef, tomatoes, and aromatic vegetables for deep, complex flavor. Taking time to make a proper Bolognese elevates this from weeknight dinner to special occasion worthy.

The sauce is so flavorful that your noodle substitute barely matters—it’s just a vehicle for this amazing meat sauce. This is worth the extra effort when you want to impress.

Keto Pesto Lasagna

Vibrant basil pesto replaces traditional sauce for a fresh, herbaceous twist. The pesto’s bright flavor cuts through all that cheese beautifully, keeping the dish from feeling too heavy. You can use store-bought pesto for convenience or make your own for better carb control.

This version feels summery and light, perfect for warmer months. The green layers look stunning when you slice into it.

Keto Buffalo Chicken Lasagna

Spicy buffalo sauce and shredded chicken create a game-day favorite in lasagna form. The tangy heat from the buffalo sauce makes this incredibly addictive and totally unique. Blue cheese or ranch dressing drizzled on top adds cooling contrast. This is messy, indulgent, and absolutely worth every bite.

It’s perfect for football Sundays or anytime you’re craving buffalo wings.

Keto Deli Meat Lasagna

Slices of deli meat like ham or turkey replace noodles in this genius, zero-prep solution. The meat adds protein and flavor while creating distinct layers that hold together perfectly. This is the fastest keto lasagna you can make since there’s no slicing vegetables or pre-cooking anything.

The deli meat crisps slightly at the edges, adding textural interest. It’s perfect for lazy weeknights when you want comfort food fast.

Keto Cauliflower Lasagna

Thinly sliced cauliflower creates surprisingly noodle-like layers with a mild, neutral flavor. The cauliflower softens beautifully during baking and absorbs sauce wonderfully. You’ll want to roast it first to remove moisture and prevent sogginess. This option is great for anyone who wants a vegetable base but finds zucchini too watery.

The mild flavor makes it kid-friendly and versatile.

Keto Pizza Casserole

This deconstructed take on lasagna brings pizza flavors to the party. Pepperoni, Italian sausage, mozzarella, and pizza sauce layer together with your choice of low-carb base. It tastes like deep-dish pizza and lasagna had a delicious baby. You can customize toppings endlessly—add bell peppers, olives, or whatever you’d put on pizza.

This is fun, casual, and guaranteed to please even the pickiest eaters.
