Keto Lasagna with Zucchini Noodles [Recipe]

Keto Lasagna Recipe | Zucchini Noodles | Low Carb | Atkins

I wouldn’t call my family “dysfunctional” per se, but we fight over lasagna, and the battle tactics are limitless. Pushing, shoving, words that cut deep, unnecessarily long silent treatment, you name it. I’ve thrown and received countless elbows scrambling to reach the coveted corner piece before my siblings, and cousins get there. That ooey gooey mozzarella with the golden crisp does crazy things to people. I never even thought of a keto lasagna.

The thing is, lasagna noodles are so not keto friendly. While avoiding lasagna induced hand-to-hand combat could be considered a positive thing, I had really started to miss our go-to family get together dish. The taste, the smell, the glorious feeling of victory when you score the piece your sister had her eye on. For me, this was always the hardest food to say no to after cutting carbs out of my diet.

When I snagged a copy of the Dinner in Five cookbook, I was overjoyed to find a low carb lasagna recipe. Like, drop everything and run to the grocery store level of joy and excitement. The recipe was a dream come true for a few reasons:

  1. Only five net carbs. This lasagna is totally safe for a ketogenic lifestyle! All of the high carb ingredients were replaced with low carb alternatives. The lasagna noodles? Thinly sliced sheets of zucchini. The sugar-laden pasta sauce? A low carb marinara. Keeping the carb count minimal can be challenging when recreating comfort food dishes, but at only five grams of net carbs, this is definitely a winner.
  2. Only five basic ingredients. In my day to day cooking, I embrace the idea of minimalist cooking. Just keeping it simple makes ketogenic cooking easier to stick with and more enjoyable. Choosing high-quality ingredients that pack a lot of flavors allows you to create great tasting food without doctoring it up too much. I’m not personally a huge fan of complicated recipes that have an excessive list of hard to source ingredients, so I was stoked to have only five things to buy. Less is more!
  3. So. Damn. Delicious. Everything about this dish was on point: the taste, the texture, the smell. I LOVE THIS DISH! Even though the main ingredients are swapped with healthy alternatives, it didn’t taste like “diet” food or feel restrictive. It completely transformed the simple ingredients into something amazing and beautiful: lasagna where I had dibs on every corner piece. It totally hit the spot. You bet your ass I’ve made this keto lasagna more than once.

The Dinner in Five cookbook is all about minimalism. The concept is brilliant: every single recipe has five ingredients or less and five net carbs or less! If you are struggling to brainstorm low carb dinner ideas and want something easy, this was tailor made for you. If you are on the keto diet or just trying to cut back on carbs, you will get a lot of value out of this cookbook.

Like the keto lasagna, the recipes are simple, satisfying and easily accessible. You won’t have to order any specialty ingredients online or scour several different grocery stores to make these recipes. These are ingredients that are on the shelf at your local grocery store.

But the coolest part about this? They are creating a series of cookbooks based off of this concept! That means it’s not just dinner, but breakfast and lunch too. With each recipe maxing out at five net carbs per serving, you could pick any combination of breakfast, lunch, and dinner from the cookbooks and be well under your carb limit for the day. That takes a lot of the guesswork out of counting carbs!

Vicky, the mastermind behind the recipes in these books, hinted that there might even be a Dessert in Five on the horizon! Love it! (Update: Dessert in Five is a real thing now!)

I loved this recipe and the concept of the series so much, I reached out to Vicky to ask permission to share the keto lasagna from her book. Lucky for you, she said yes! Enjoy!

    • This recipe is perfect, I like it better than normal lasagna for sure. I didn’t miss noodles, jut remember it’s more watery due to zucchini. I drained water down after I cut out a few slices and made sure it sat to rest for 20 minutes before I served.

  • Dinner with your family growing up sounds so much more fun than mine! We sat at table, minding our manners, asking politely for things to be passed or waited patiently for mother to serve us a second helping – a real snooze fest. Luckily, my mother made wonderful lasagna. I miss it. I can’t wait to try this 5 ingredient low carb version. Your photos make it look just divine!

    • Tomato Sauce not Spaghetti Sauce that is canned has very little additives and a lot less sugar and carbs. Tattoos so has 4g carbs & 2g sugar which is just as good as Rao’s 3 carbs & 3 sugars.

    • You can make a keto marinara w/ canned tomatoes that is super easy. 2 cans tomatoes, 1/4 cup olive oil, 1 tsp red wine vinegar, salt, pepper, powdered garlic, powdered onion, then you blend in a blender. No cooking necessary! Believe me, it has amazing flavor!

  • Hello

    Just wondering what size pan and how many total carbs in the dish? I am headed to Super Target now to grab my ingredients!!!

  • I’m sorry. This is probably a really stupid question. What do you mean by “leave out core”? Also, what do you use to peel the zucchini? Just a regular vegetable peeler? Thanks!

  • Just a thought, if you use thinly sliced eggplant instead of zucchini (salt the slices and let them sit for 15 minutes just like the zucchini) you should have eggplant parmesan.

  • I’ve made this before. It’s awesome.

    If you want to fry the zucchini in pork rinds and parm first, it gives it more flavor and a little firmer texture.

  • Hi,

    I’m working on a round-up of keto casserole recipes for The Huffington Post Taste and I’d love to feature your recipe. Please let me know if you’re interested. Thanks!

    • You have to soak the zucchini in salt for 20-30 minutes to draw out the water, it won’t be that soupy watery if you do this.

  • My mom always diced some pepperoni and sauteed it with the beef. Gives that extra little something! BTW, does the zucchini give off a lot of water? I haven’t tried this recipe before because I just knew it would be soupy. Your photo gives me hope.

  • Can i just say that the images are so large that i’m unable to enjoy them on a standard desktop? I see the images as they’re scrolled, never in their entirety. Kind of ruins the experience.

    Nevertheless, its a delicious recipe which i just made 🙂

  • I’ve made this. Edited and it was exo! Can I double the recipe and freeze? I’m all about easy weeknight dinners!

    • I haven’t personally tried freezing it but that’s a great idea! All of the ingredients appear to be freezer friendly – you could construct the dish in a freezer safe pan and pop it in the oven when you’re ready to eat. I’m sure it would adjust the amount of time it would require to bake but other than that, I think it’s a solid idea. If you try it please let me know how it works out and I can add a note to the recipe! <3

  • No answer to the ? about size of pan, but my common sense tells me to use a pan that you can divide into 4 perfect servings, not like the one pictured. The one pictured is showing 6 servings so I would assume that it is 1.5 times the recipe! 🙂 What I’m wondering is, to “peel” the zucchini, do you #1 Use the green part? and #2 Cut it in half lengthwise first to scoop out the core? I’m going shopping for the ingredients right now, so if there’s no answer by the time I get back, I’ll just carry on! My mouth is already watering!

    • The green outer part of the zucchini is pretty tough, even when cooked. I typically discard it when it’s just the outer dark green portion, but I don’t bother taking it off if it’s just part of the cut. Re: the core, you can definitely do either way! I’ve done it and seen it done both ways. Personally, I just start peeling until I hit the core of seeds and discard that part once all of the zucchini flesh has been cut off.

      For dish size, I used a 9 x 6 baking dish from ikea. You can use a square dish or something similar in size to what I used without increasing ingredients. I cut it into 6 servings because I thought it looked prettier in the pictures, but you can definitely do 4 large servings as the original recipe calls for! 🙂

    • The ricotta definitely gives it that traditional lasagna texture, but I’m sure subbing in a different cheese would really tasty as well.

      When I was a kid, my mom would use cottage cheese if we didn’t have ricotta on hand. 🙂

  • Just wanted to say thank you for this fabulous recipe! So incredibly quick, easy and delicious. I’ve been experimenting with the keto diet and many of the recipes are unnecessarily complicated it seems. Love the simplicity of this, and of course, it’s my fave dish of all time (who doesn’t love lasagna!). So thank you again!

  • Making this tonight, but I’m using shredded leftover chicken instead of ground beef. I also have a cool new vegetable sheet slicer for my Kitchen Aid mixer that I’m dying to use. Can’t wait to try it. Getting in the mood for my trip to Italy in May!

  • I made this tonight for Valentine’s Day dinner! So easy to make and incredibly delicious! (I doubled your recipe to make a full pan of lasagna for leftovers.) It was a huge hit with my keto husband who was thrilled with the 6 grams of carb too! Thanks for a great recipe! I’ll be back!
