What kind of slow cooker do I need?

Any slow cooker will work for this recipe, but you will need to be mindful of of the size and shape to determine the cooking time.

I recommend using a mini casserole slow cooker but here are some other options as well.

  • I prefer an oval slow cooker for more even cooking
  • If it’s larger than 3 quart you will need to reduce cooking time (a slow cooker that is less full will cook food faster)
  • For a round slow cooker, you may need to increase cooking time to heat the food all the way through the middle

Other tips for making taco casserole:

  • I recommend shredding your own cheese from a block for better melting
  • you can use regular or fire-roasted canned diced tomatoes
  • for a spicy taco casserole, you can leave the seeds in the jalapeños or use canned jalapeños

What to do with the leftovers:

Portion into individual serving containers and store in fridge for up to 2 days or freezer for up to 3 months.

Warm in microwave until heated through.

  • sour cream
  • more fresh chopped cilantro
  • fresh salsa

    Made this yesterday, and wow! So delicious! Got to thinking, might try it with shredded chicken next time (probably will double the enchilada sauce to account for the increased volume). Maybe add black olives and onions, too. Jennifer, I’m officially addicted to your website!

    This is a really good way to use up an opened pack of tortilla chips which we often end up with and they are not nice stale. Thanks for the recipe – it’s great to see some veggie slow cooker ideas that are a complete meal rather than being a side dish.
