We'd love for you to share!

Crock Pot Vegetable Lasagna is stacked a “mile high” with vegetables, 3 cheeses and whole wheat noodles. Just layer everything in your slow cooker and then sit back and wait for the applause.

Crock Pot Vegetable Lasagna

It’s hard to believe that there are 6 cups of vegetables piled high in this Crock Pot Vegetable Lasagna. You can see the carrot peeking out between the cheesy layers. What you can’t see are the slices of zucchini, mushroom and red onion. They are smothered in a creamy ricotta and mozzarella cheese mixture and a generous portion of pasta sauce.

This recipe is a personal favorite of mine. Sit me down with a serving and I’m a happy camper. It’s a satisfying one dish meal. And, there are usually leftovers. I individually wrap single servings and freeze them for days when I need a quick dinner or lunch.

I used the technique from Crock Pot Baked Ziti and the ingredients from Roasted Vegetable Lasagna to come up with…

In case you’re new to the pasta in the crock pot technique, here are some tips and pics.

Broken Lasagna Noodles in Crock Pot

Buy regular lasagna noodles (not the no-boil kind.) Either way, the noodles are not boiled first. Whole wheat noodles are pictured.

Place the noodles in a layer across the crock pot, breaking the noodles when necessary. It won’t be pretty. The noodles will overlap and there may be some gaps. No one will ever know. 🙂

Ricotta mixture for Crock Pot Lasagna

Spreading the cheesy layer over the broken noodles can be tricky. Drop small scoops of the cheese mixture over the noodles. (I use a 1 Tablespoon cookie scoop to this.) Use a spoon (or your fingertips) to gently spread the piles of cheese over the noodles.

Chopped Vegetables for Lasagna

Layer the vegetables over the cheese and then top with a generous portion of pasta sauce.

Keep layering…there will be 3 layers of vegetables and 4 layers of noodles. I know. It’s a lot! I used a 5 1/2 quart slow cooker. If you have a large crock pot, you could spread everything over 3 layers of noodles instead.

Set the crock pot on low and let the magic begin. The cheese and sauce softens the noodles and the veges become tender and soft.

At 4 hours, turn off the crock pot. Take off the lid and sprinkle the remaining cheeses over the top. Return the cover and allow the lasagna to sit for at least 30 minutes more (or up to one hour.) The cheese will melt and the lasagna will “set” and you will be left with…
