Slow Cooker Zucchini Lasagna
Healthier veggie noodles are popular for a reason! The Slow Cooker Zucchini Lasagna will give you that pasta fix without all the guilt!

I finally figured out that not only do I need to salt the zucchini very well, I need to let it sit and drain for a decent amount of time. Hard for this impatient girl, but it really does make a difference. Finally, you need to find something that can help you press a lot of the water out as well. I used a potato masher. Not ideal, but it did the job.
You’ll want to cut your zucchini in strips along the length about 1/4 thick so you will need a super sharp knife. Take your time here and get them as even as possible. If you have a mandoline slicer, your job will be so much easier, but it’s not a requirement. I don’t have one, but am thinking of giving one a try. This is the one I’m looking at. Anybody have it or another they would recommend?
Plenty  of cheese is the next requirement and I strongly recommend you grate the cheese yourself. I used a blend of provolone, mozzarella and parmesan. And of course, ricotta.
Last up, you’ll either want to make your own, or find a really great marinara that you love. I do love my homemade version the most, but since I don’t always plan ahead and tend to make dinner decisions based on current day cravings, sometimes I pick some up at the store. I always look for something with no sugar added. And with plenty of roasted garlic, but that’s because I tend to be a garlic freak, so the garlic thing is totally up to you.
I cooked this up in my new little mini casserole slow cooker and it was the perfect size for 4-6 servings since I knew I didn’t want tons of leftovers on this one.
