Let’s be real – sometimes you just need lasagna. That comforting, cheesy, saucy goodness is like a hug on a plate. But traditional lasagna, while amazing, can feel a bit heavy, especially on a weeknight. For ages, I tried different ways to lighten it up, but nothing quite hit the spot until I swapped the pasta for layers of tender zucchini. Game. Changer.
Seriously, this Low-Carb Zucchini Lasagna Bake delivers all those cozy, savory flavors you crave, but in a lighter, veggie-packed way. It became an instant hit in my house (even the picky eaters approved!), and it’s perfect when you want pure comfort food without the carb coma afterwards. Plus, leftovers are fantastic for lunch!
Why This Recipe Totally Works
- Veggie Powerhouse: It’s loaded with zucchini, making it a fantastic way to sneak in extra vegetables while still feeling indulgent.
- Classic Lasagna Flavor: You get the rich meat sauce, creamy ricotta filling, and gooey melted cheese – all the essential elements are here!
- Low-Carb & Keto Friendly: By ditching the pasta, this bake fits perfectly into a low-carb or keto lifestyle without sacrificing flavor or satisfaction.
Let’s Talk Ingredients
Here’s the rundown of what you’ll need:
- 1.1 lbs Zucchini: Look for firm, medium-to-large zucchini. About 1 large and 1 medium usually does the trick.
- Fine sea salt: Helps draw out excess water from the zucchini – crucial!
- 2 tsp Olive oil: For sautéing the aromatics and browning the beef.
- 1/4 cup Yellow onion, finely chopped: Adds a nice flavor base to the sauce.
- 1 large Garlic clove (or 2 small), minced: Because garlic makes everything better.
- 12 oz Lean ground beef: 90% lean or higher works well to keep it from getting too greasy.
- 1/4 tsp Red pepper flakes (optional): Adds a gentle warmth; omit if you prefer no spice.
- 1.5 cups Marinara sauce, no sugar added: Read the label! Finding a sauce without added sugar is key for keeping it low-carb and diabetic-friendly.
- 1.25 cups Ricotta cheese (approx. 10 oz): Whole milk or part-skim both work; whole milk will be richer.
- 3/4 tsp Dried oregano: That classic Italian herb flavor.
- Pinch of black pepper: For seasoning the ricotta.
- 2 cups Shredded mozzarella cheese (part-skim recommended), divided: For that essential cheesy topping and layers.
Step-by-Step to Lasagna Bliss
- Prep the Zucchini: Get your oven preheating to 360°F (180°C) with the rack in the middle. Line two big baking sheets with parchment paper (makes cleanup easier!). Trim the zucchini ends. Now, carefully slice the zucchini lengthwise into thin planks, about 1/8-inch thick. A mandoline slicer is super helpful for getting even slices, but a steady hand and a sharp knife work too!
- Give Zucchini a Quick Bake: Lay the zucchini planks in a single layer on your prepared baking sheets. Don’t overlap them too much. Sprinkle them lightly with fine sea salt. Pop them into the oven for 8-10 minutes. This step is SO important – it helps remove extra water so your lasagna isn’t soupy. Take ’em out and let them cool slightly.
- Start the Meat Sauce: While the zucchini is doing its thing, heat the olive oil in a skillet over medium-high heat. Toss in the chopped onion and cook until it starts to soften, maybe 3-4 minutes. Add the minced garlic and optional red pepper flakes, stirring for about 30-60 seconds until you can smell that lovely garlic aroma.
- Brown the Beef: Add the ground beef and a little pinch of salt to the skillet. Cook, breaking it up with your spoon, until it’s nicely browned and no pink remains (about 6-8 minutes). Carefully drain off any extra fat.
- Sauce it Up: Scoop out about 1/3 cup of the marinara sauce and set it aside. Pour the rest of the sauce into the skillet with the beef. Stir everything together and let it heat through for a minute or two. Then, take it off the heat.
- Mix the Ricotta: In a small bowl, just stir together the ricotta cheese, dried oregano, and a pinch of black pepper. Easy peasy.
- Time to Layer!: Grab an 8×8 inch or 9×9 inch square baking dish. Spread that reserved 1/3 cup of marinara sauce on the bottom. Arrange about one-third of your zucchini planks over the sauce. Dollop half of the ricotta mixture over the zucchini, spreading it out gently. Top that with half of the meat sauce. Sprinkle 3/4 cup of the mozzarella over the meat sauce.
- Repeat, Repeat! Do it all again: another layer using the next third of the zucchini, all the remaining ricotta, and all the remaining meat sauce. Sprinkle another 3/4 cup of mozzarella on top.
- Final Touch & Bake: Finish with the last third of the zucchini planks. Sprinkle the remaining 1/2 cup of mozzarella evenly over the top. Now, into the 360°F (180°C) oven it goes for 25-30 minutes. You’re looking for it to be hot, bubbly all around, and the cheese completely melted and gorgeous.
- (Optional) Get Golden: Want that classic browned cheesy top? Switch your oven to the broiler setting for just 1-3 minutes at the very end. Watch it like a hawk – it can go from golden to burnt super fast!
- Let it Rest! This is important! Take the lasagna bake out of the oven and let it sit for at least 10-15 minutes before you try to slice it. This lets the layers settle so it doesn’t fall apart when you serve it. Don’t panic if you see a little liquid pool in the bottom – that’s normal.
- Serve it Up: Slice into 6 portions and enjoy warm! Store any leftovers covered tightly in the fridge for up to 4 days.
My Top Tips & Tricks
- No Mandoline? No Problem: If slicing zucchini evenly is tricky, you can cut slightly thicker planks and just pre-bake them a few minutes longer. The key is consistency.
- Meat Variations: Feel free to swap the ground beef for ground turkey, ground chicken, or even crumbled Italian sausage (check labels for added sugar if using sausage).
- Veggie Boost: Want even more veggies? Add a layer of sautéed spinach (make sure to squeeze out ALL the excess water) mixed into the ricotta filling.
- Make Ahead: You can fully assemble the lasagna bake (up to step 9 before baking), cover it tightly, and refrigerate it for up to 24 hours. You may need to add 5-10 minutes to the baking time if baking straight from the fridge.
- Avoid Watery Lasagna: The two most important tips here are pre-baking the salted zucchini and letting the finished lasagna rest before slicing. Don’t skip these!
Serving & Pairing Perfection
This Zucchini Lasagna Bake is hearty enough to be the main course! Serve it with a simple side salad drizzled with Italian vinaigrette for a complete meal. Some low-carb garlic bread or keto breadsticks would also be fantastic for soaking up any extra sauce (yum!).
It’s perfect for a cozy family dinner, meal prepping lunches for the week, or even bringing to a potluck where you need a delicious low-carb option.
A Note for Visitors Managing Diabetes

Low-Carb Zucchini Lasagna Bake
Enjoy all the comforting flavors of lasagna without the pasta! This bake uses thinly sliced zucchini planks layered with a savory meat sauce, creamy ricotta, and melted mozzarella for a delicious low-carb and veggie-packed meal.
Ingredients
Method
- Prepare Zucchini: Adjust oven rack to the middle position and heat oven to 360°F (180°C). Line two large baking sheets with parchment paper. Trim the ends from the zucchini. Using a mandoline or a very sharp knife, slice the zucchini lengthwise into planks roughly 1/8-inch thick.
- Pre-Bake Zucchini: Arrange zucchini planks in a single layer on the prepared baking sheets. Sprinkle lightly with fine sea salt. Bake for 8-10 minutes, just until slightly softened. Remove from oven and set aside.
- Make Meat Sauce: While zucchini pre-bakes, heat olive oil in a medium skillet over medium-high heat. Add the chopped yellow onion and cook until softened, about 3-4 minutes. Add the minced garlic and optional red pepper flakes; cook for another 30-60 seconds until fragrant. Add the ground beef and a pinch of salt. Cook, breaking up the meat, until browned, about 6-8 minutes. Drain off excess fat.
- Finish Meat Sauce: Reserve approximately 1/3 cup of the marinara sauce. Pour the remaining marinara sauce into the skillet with the cooked beef. Stir to combine and heat through. Remove from heat.
- Prepare Ricotta Filling: In a small bowl, combine the ricotta cheese, dried oregano, and a pinch of black pepper. Stir well.
- Assemble Bake: Spread the reserved 1/3 cup of marinara sauce over the bottom of an 8x8 inch or 9x9 inch square baking dish. Arrange a layer of zucchini planks over the sauce (using about one-third of the slices). Top with half of the ricotta mixture, spreading gently. Top with half of the meat sauce mixture. Sprinkle 3/4 cup of the shredded mozzarella cheese over the meat sauce.
- Repeat Layers: Create a second layer starting with another third of the zucchini planks, the remaining ricotta mixture, and the remaining meat sauce. Sprinkle another 3/4 cup of shredded mozzarella cheese on top.
- Final Layer & Bake: Place the final third of the zucchini planks over the mozzarella. Sprinkle the remaining 1/2 cup of mozzarella cheese evenly over the top. Bake at 360°F (180°C) for 25-30 minutes, or until the bake is hot, bubbly, and the cheese is fully melted.
- Optional Browning & Rest: For a more golden top, switch the oven to the broiler setting for the last 1-3 minutes, watching very carefully to prevent burning. Remove the bake from the oven and let it rest for at least 10-15 minutes before slicing and serving.
- Serve & Store: Slice into 6 portions and serve warm. Leftovers can be stored, covered tightly, in the refrigerator for up to 4 days.
