Vegetarian Crock Pot Vegetable Lasagna

This weeks Crock Pot Vegetable Lasagna recipe is one of my new favorite crock pot vegetarian recipes. The first time I made this Vegetable Lasagna recipe I made it in an 8 x 8 baking pan and had one of my worst kitchen blunders happen the next day.

To keep from heating up my house I turned it into a Crock Pot Vegetable Lasagna recipe. It is steaming hot here in Florida already and my old air conditioner is worn out and struggling. So I decided this recipe needed to be a Crock Pot Vegetable Lasagna recipe so I could enjoy it without heating up the whole house.

I recently bought a mandoline and the minute I bought it I knew I was going to make this vegetarian lasagna recipe. I've been seeing all these fun vegetable recipes made with squash and zucchini sliced paper thin with a mandolin. I've also seen all those Zoodle recipes on Pinterest.

Well I bought one of those Zoodle thingies but it was really hard to use and my zoodles never looked like noodles. They reminded me of worms honestly so I never got into the making any recipes with zoodles. But I knew I would come up with something delicious using my new  mandoline.

I'm so glad I bought the mandoline because not only did I make this Crock Pot Vegetable Lasagna but I used it again today to make some kosher dill pickles. I made my own dill sandwich slices and pickle rounds with it. It is a handy little gadget.

As I mentioned I made this delicious Vegetable Lasagna recipe previously. When I made it that time I made this huge 8 x 8 tray. I went way overboard with the ricotta and mozzarella cheese. I swear that 8 x 8 tray must have weighed at least 6 pounds between the ingredients and the weight of the stoneware baking dish. I loved that stoneware baking dish.

Did you catch the past tense there? I said LOVED it. I used it to make my Meatball & Ravioli Lasagna. I used it to make this Savory Cheesy Chicken Broccoli Rice. It was pretty much my go to casserole dish since I bought over the holidays last year.

Well the day after I made this Vegetable Lasagna the first time I was taking it out of the refrigerator to heat up some leftovers for lunch and as I went to place it on the counter it slipped out of my hands and fell to the floor in one big cheesy mess. The casserole dish shattered. The vegetable lasagna was splattered all over the floor, my legs and my white kitchen cabinets.

I don't know what upset me more. Not being able to enjoy another piece of the vegetable lasagna for lunch or the loss of my favorite casserole dish!

At that very moment I was more upset over not being able to enjoy another serving of the vegetable lasagna. I figured I could just go buy another casserole dish. NOT!

I have searched high and low. I only found one casserole dish that looked a lot like the one I broke and it was in a grocery store with a $29.99 price tag. I loved that casserole dish but there is no way I am paying $30 for the only one I saw. I know I only paid about $15 for the one I bought. So for now I will have to do without. I still have plenty of metal or Pyrex baking dishes that I can use.

Special equipment needed: You will need a mandoline to make this recipe. The yellow squash and zucchini are sliced paper thin. I swear you can hardly tell you are eating a vegetable when the squash is cut paper thin and cooked  like this.

I did make one very important change this time around. I cut way back on the amount of sauce I used. I went pretty heavy on the sauce the first time around thinking the squash would need the liquid to cook in.

What I forgot is that the squash holds moisture that is released when cooked. I cut back to a minimal amount of sauce for the Crock Pot Vegetable Lasagna. If you like a more saucy lasagna serve some along side or else the Crock Pot Vegetable Lasagna will be to saucy and you may not be able to get it out of the crock pot in serving sized pieces without it falling apart.

Also I used a 24 oz jar of sauce because that was what I had on hand. If you have a smaller jar you can use it. There will be sauce left over if you use a 24 oz jar. I plan on using my leftover sauce  to top a  homemade pizza.

  7. Assemble the vegetable lasagna in the bottom of your crock pot using the following steps.
  8. Spread a scant ¼ cup of the sauce over the bottom of the crock pot.

    I am the caregiver for my lovely 81 year old wife. There are a lot of foods he cannot tolerate. I am thankful to say that she can handle all the ingredients in your recipe. We re from Ft. Myers, our work took us to Sarasota. Wanted to go back when we retired but she became ill with a multitude of problems. Our kids and their kids are here. Se iss from a large Italian family She teaches me her heirloom recipes and we try to adapt them with a touch of my Southern mom,s cooking. I am 80 years old and enjoy cooking for the love of my life. Thank you so very very much. What a time saver. Sincerely, Bill

    Wow! That crock pot lasagna looks really delicious! And sorry that your air-con is struggling because of the heat there in Florida. Anyway, this vegetable is something I'm really looking forward to make. It's very healthy. Thanks for sharing!
