I’ve been on a casserole kick lately, especially ones that you can make ahead of time. It’s amazing how much easier your life becomes when you do a little meal prep ahead of time.
The fact that you can assemble this up to 2 days ahead of time is really handy. And the ingredients are really easy to customize.
Layers in Taco Casserole
This recipe includes the following layers of ingredients, in order from first to last:
- Refried Beans
- Sour Cream – avoid using light sour cream as this can cause it to curdle and separate.
- Seasoned Ground Beef and Onions
- Cheese
- Black Olives
- Tomatoes
- Crunchy Toppings. (Tortilla Chips, Doritos, and/or Fritos.)
Additional Ingredient Options:
- Shredded Chicken, beef, or Pork
- Finely sliced steak. (Sirloin, flank steak, or skirt steak is best.)
- Ground chicken or turkey.
- Guacamole
- Salsa
- Black Beans
- Rice
- Diced Jalapenos
- Bell Peppers
- Corn
- Cilantro
- Tator Tots (because, why not?!)
How to Make it
Cook/crumble the ground beef and onions in a pan over medium-high heat.
Drain excess grease, add water and taco seasoning. Bring to a boil, reduce to a simmer for 5 minutes, then remove from heat.
Spread the refried beans in an even layer over a 9 x 13″ casserole dish. Top with sour cream.
Add the seasoned ground beef and onions on top.
Top with cheese. Bake uncovered at 350°F for 15 minutes, until the cheese is hot and melted.
Add the black olives and crunchy toppings. Bake uncovered for 8 minutes.
Garnish with green onions, diced tomatoes, and/or shredded lettuce if desired and serve!
Make-Ahead Method
This Taco Casserole can be made up to 2 days ahead.
- To do so, cook the ground beef and onions and layer all of the ingredients in a casserole dish.
- Let it cool and cover it. Refrigerate for up to 2 days.
- Bake, covered, in a 350° oven for 25 minutes.
- Uncover, and bake for 5 more minutes to fully melt the cheese.
- Add black olives along with the crunchy toppings. Bake for 8 additional minutes.
- Add the shredded lettuce, diced tomatoes, and green onions prior to serving.
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/tomatoes/green onions until you’re just ready to serve.
Heating right away: High 2-3 hours or Low 4-5 hours
Heating from a cold state: High 4-5 hours or Low 6-7 hours
This Crock pot allows you to sear/brown meat right on the stove top. It also switches to warm once the cooking time is up.
Note that 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. Click the number of servings to reveal a slider. Move the slider right to increase the number of servings if you’re making this for a larger crowd.
Storing Leftovers
- 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!
Freezing
- Taco casserole makes a good freezer food and can be stored for up to 3 months, although I recommend that you leave out the sour cream and serve it on the side with this casserole if you plan on freezing.
- Leave out the crunchy toppings and shredded lettuce when you freeze as well.
- Let it defrost overnight and bake as instructed, or bake it frozen and add 1 hour of baking time.

5 stars for another delicious dish! We all loved it and it’s all gone!! Very easy to make and versatile too! I love how easy your recipes and pictures are easy to follow!
Awesome Kesha! I’m so glad to hear that the pictures help, I always like to try to make it as clear and easy as possible so I’m glad it’s working!! -Stephanie
Easy recipe to follow and I followed it exactly. I used regular sour cream and it still curdled and separated. I would definitely recommend adding the sour cream last as a topping rather than in the middle of the dish.
WHEN DO WE ADD THE RICE IF USING SAFFRON RICE FULLY COOKED? AFTER? AND TOP THE CASSEROLE ON TOP>
Hi Maureen! You could add it right on top if you’d like, once the casserole comes out of the oven, or you could serve it on the side! Another option would be to add it as a layer, maybe right before the ground beef!
This looks so delicious. I would love to make it in advance by 2 weeks.
For freezing… Bake first, then freeze, correct?
Then can you reheat it in the oven from frozen?
How does the sour cream fare?
Hi Joelle! You could layer it all together and bake it without baking it, although I would leave out the sour cream and serve that on the side instead just to be safe. I just updated the freezing instructions to make that more clear! When you bake it, let it thaw completely in the fridge and bake as instructed, or add one hour of baking time if baking from frozen. Enjoy!! 🙂
This turned out great. I made a few changes. But was so great
Great to hear Paul!😃 It’s a great way to put a new spin on Taco Tuesday!
