👩🏻🍳 Slow Cooker Zucchini Lasagna
Slow Cooker Eggplant & Zucchini Lasagna is the best Low Carb Lasagna recipe ever. It's made with Eggplant and Zucchini ribbons so it's naturally gluten-free.
Also, it's so easy to make and of minimal effort, because you don't have to cook the noodles separately.
You're basically just dumping everything and baking in the slow cooker! Isn't it so much fun!!!
I was so skeptical before making this recipe that my Lasagna will not turn out to be perfectly baked as it gets in the oven. But, I was so wrong.

Not only did the Lasagna bake to perfection, but it tasted even better than a traditional Lasagna. Bursting with flavors of Marinara, Garlic, Cheese, and Italian Seasoning, this is so delicious.
Also, it's so effortless and hasslefree! 😍

👩🏻🍳 Instructions
STEP 1: Slice Eggplant and Zucchini

- Use a Mandolin slicer to slice the Zucchini and Eggplant
- Season them with salt and pepper and let rest for 2 hours
- After 2 hours, squeeze out the excess moisture and drain the water released from the noodles. Pat fry these veggie noodles using a paper towel.
STEP 2: Make Three Cheese Mixture

- To make the Three Cheese Mixture, combine Mozzarella Cheese, Parmesan Cheese, and Skinny Ricotta Cheese
STEP 3: Layer the Lasagna and Slow Cook
- Grease the pot of the Slow Cooker with Olive Oil
- Start Layering. The first layer will be of noodles, followed by the cheese mixture, followed by Marinara Sauce and finally Mozzarella Cheese. Repeat until you use up all your noodles or you reach to the rim of the Slow Cooker.

- Cover with the lid and cook on high for 4 hours or on low for 8 hours.
STEP 4: Garnish & Serve
- After 4 hours, garnish with chopped Cilantro.
- Cut the Lasagna and serve.
Remember to drain the water of the veggie noodles before layering them or else your Lasagna WILL GET WATERY!
Hint: I would suggest you Season the Veggie Noodles and place them in the oven and roast at 400F for 8 minutes.
Doing this will get rid of all the moisture from Zucchini and Eggplant Noodles and shall make sure that your Lasagna is baked to perfection and does not get watery!

💯 Top tips
- Soak out the Moisture from the seasoned Eggplant and Zucchini or else your Lasagna will be watery.
- You can roast the veggie noodles by placing them in a greased sheet pan and baking at 400F for 8-10 minutes.
- Cook for 4 hours on High or 8 hours on Low in the Slow Cooker
- Use a Mandolin Slicer to slice the Eggplant and Zucchini. It's easy to use and gets you perfect slices of even thickness that get cooked evenly. However, make sure that you use it carefully as the blades of a Mandolin slicer are too sharp. You can wear a cooking glove and then use it to slice the veggies.
