Mixed Bean Casserole

Looking for a freezer to crockpot recipe that’s super easy but healthy too? Give this Mixed Bean Casserole a try.beans, corn, diced sweet potato in a tomato broth in a bowlThe day I took this meal out of the freezer to make it for the first time, something unintentionally happened. I had it in the crockpot ready to serve and when my husband arrived home, I went upstairs to take an important phone call.

I came downstairs a short while later to join my husband and kids. He had brought out flour tortillas, sour cream, and cheese. They were using my casserole as a wrap filling… genius!

Though this idea had not occurred to me, the kids really enjoyed them the next day as leftovers in wraps again. Whether you choose to serve this as a wrap filling or as a casserole, it’s healthy and hearty.

Ingredients Needed

  • Pinto beans – The main ingredient for this mixed bean casserole is pinto beans. I like to use a can of chili style pinto beans. Of course, you can use whatever you’d like! 
  • Black beans – This recipe involves mixed beans, so you will need black beans. However, you can choose to use whatever beans you’d like. 
  • Taco seasoning – I prepare my own taco seasoning, but you can use whatever brand you’d want. 
  • Salsa – This is the perfect recipe to use homemade salsa in, but I always tend to use a jar because that’s what I have on hand. 
  • Frozen corn – A great addition to this casserole is corn. It helps pull all of the ingredients together, plus anytime you can add a vegetable to a casserole, it’s a win-win! 
  • Sweet potato – I only used one sweet potato and cubed it, but you may add more sweet potatoes if your heart desires. Sweet potatoes are so good for you and any time you can add them to a meal, go for it.
