Freezer Meal: Slow Cooker Veggie Lasagna

vegetable lasagna on white plateSo I asked on Facebook yesterday how everyone felt about freezer meals and the consensus is that we need them!! We are some busy people with some important stuff to do and we need to get some healthy and delicious meals on the table with minimum effort. I’ve got a few more ideas in the works but for today I have a delicious veggie lasagna! Spend a little time on the weekend assembling the ingredients and have two dinners worth in your freezer ready to go!

Slow Cooker Veggie Lasagna on white plate with salad in backgroundI don’t know about you but I find it pretty relaxing to chop some veggies and measure ingredients. I made this recipe and one other, so four meals in total, the other morning with the TV on and a peaceful house. It felt good to have it done and now I have a backup any night of the week when things get crazy!

Toss it all together with the sauce and divide the filling equally between two large ziploc bags. All you will need to have on hand for cooking day is a box of lasagna noodles and some extra cheese!

Slow Cooker Veggie Lasagna on white plate I also want to say that you can totally customize the veggies you use here to your liking. It’s almost like a kitchen sink kind of recipe. Throw in whatever you have! Make it a little different every time.

To assemble you will put a little sauce down, break up some noodles, lay another layer of sauce down and repeat a few time. Make sure you leave plenty of sauce for the top and then load it up with some more cheese!

Slow Cooker Veggie Lasagna on white plateIf you will be out of the house all day, make sure you use a crock that can switch to warm after the programmed amount of time or else wait and start this around lunch time. If you let it go way to long you could end up with a mushy and/or burnt mess. Also be sure you let it sit with the lid off and the heat turned off for about half an hour and it will be a cinch to cut and serve! This will feed about four people (we still have a little left over, too) and I made it in a 5 quart oval crock.

Important nutritional disclaimer


    1. I havnen’t tested it out specifically but typically the best temp for casseroles and lasagnas would be 350 degrees. The amount of time will depend on how big your mini dishes are, but I would say somewhere between 20-40 minutes as a starting point.

  1. Hi. When do you add the vegetables to the slow cooker? I only see where it says to add the sauce and noodles. Thank you!
