Crock Pot Taco Casserole
- This recipe is easy to assemble within a Crock Pot and heat right away or up to 2 days later.
- You’ll still need to brown the ground beef first, then layer the ingredients per the recipe instructions.
- Save the crunchy toppings and shredded lettuce/green onions until you’re just ready to serve.
Heating right away: High 2-3 hours or Low 3-5 hours
Heating from a cold state: High 3-5 hours or Low 5-7 hours
Crock Pots vary in terms on how quickly they heat up and how hot they get.
Taco Casserole for a Crowd or Potluck
- These aluminum foil pans make it easy to prepare this recipe for a crowd and the pans can be disposed of afterwards.
- This recipe serves 6 people. There is a slider on the top left of the recipe card that can be moved to increase the number of servings if you’re making this for a larger crowd.
- Leftovers should be refrigerated in an airtight container and are best if used within 3-4 days.
- Reheat in a microwave or a 350°oven until heated through.
Pro Tip: Leftovers make a great dip or filling for burritos!
- Taco casserole may be frozen, and it’s best to remove the crunchy toppings and shredded lettuce prior to doing so to prevent them from getting soggy.
- Store in an airtight container in the freezer for up to 3 months.
- Let it defrost overnight and reheat in a microwave or 350°oven until heated through.

- Bring to a boil.

- Spread the refried beans in an even layer within a casserole dish. (Mine was 13.25"x9" but varying sizes are fine.)
