This John Wayne Casserole is made with a twist—tater tots! This hearty slow cooker casserole starts with a layer of potatoes, followed by a creamy, cheesy sour cream mixture, seasoned ground beef, and is finished with a generous topping of melted cheese.
I love making casseroles in the slow cooker if you want to try a few other great ones try my Slow Cooker Chicken Cordon Bleu or Chicken Enchilada Casserole recipes.
I don’t think John Wayne had anything to do with this casserole—the name likely comes from its western-style ingredients. The original version uses biscuit mix, but a reviewer once mentioned having it with tater tots at a restaurant. That’s the perfect slow cooker twist—tater tots make it easy and delicious!
I have a beloved standard crockpot tater tot casserole recipe that I adore on my site, so I knew exactly how to assemble this new creation. I also make a chicken and bacon tater tot casserole that you must try too!

This slow cooker casserole is easy to put together with simple ingredients. Find the full recipe in the recipe card below the images.
This easy meal starts with frozen tater tots, topped with taco-seasoned ground beef, onions, and peppers. A creamy sour cream and cheddar layer goes on next, finished with more cheese and optional fresh toppings like tomatoes or peppers.

How to Make John Wayne Casserole
Here is my method for making this easy slow cooker casserole. Once you get your ground beef browned, it comes together quickly.
Step One: I add the bag of tater tots to my slow cooker.
Step Two: Then I brown a pound of hamburger with bell pepper, onion, taco seasoning, and water, I pour that meat mixture over the tots.
Step Four: Then I make a sour cream and cheese mixture with a bit of seasoning and spread that on top of the meat.
Step Five: Cook on LOW for 4.5 hours, and then top with more cheese. I put the lid back on the slow cooker, and the cheese melts in minutes.
My Serving Suggestions
Being that we make this so often, we know exactly how to serve it:
- I like to top this delicious casserole with tomatoes and green bell peppers. The cool tomatoes, along with the crunchy contrast of the bell peppers, really make the dish.
- You can also top the casserole with sour cream and green onions.
- Other serving ideas are a side of cornbread or green salad.

Ingredients
- 32 oz. bag tater tots, (frozen, not thawed)
- 1 lb. ground beef,
- 1 small yellow onion, diced
- 1 green bell pepper, diced
- 1 oz. taco seasoning mix, (I use Lawry's)
- water, add the amount of water to the meat that the taco mix says to add, 2/3 cup is what my packet said
- 16 oz. sour cream
- 8 oz. sharp cheddar cheese (divided, half in sour cream mixture and half on top at the end)
- 1/8 tsp. salt
- 1/4 tsp. pepper
- 1/2 tsp. onion powder
optional toppings
- diced tomatoes
- bell peppers
Instructions
- Spray a 6-quart oval slow cooker with non-stick spray. Add the tater tots down in an even layer, so there isn't a high spot.
- In a large skillet, set over medium high heat, brown the hamburger, onions and bell pepper. When the meat is browned, drain the fat. Add the amount of water the taco packet says to add to the meat (my packet said to add 2/3 cup). Add the taco packet, and continue cooking and stirring until the meat and the seasoning has thickened.
- Pour the meat mixture over the tater tots in the slow cooker.
- In a medium sized bowl add the sour cream, salt, pepper, onion powder, and half of the cheese (this is about a heaping cup of shredded cheese, save the other half to top the casserole at the end.)
- Spread this sour cream cheese mixture over the meat mixture in the slow cooker.
- Cover and cook on LOW for 4.5 hours, without opening the lid during the cooking time.
- After the cooking time is up add the remaining cheese evenly over the casserole.
- Cover and let the cheese melt, this will only take about 5-10 minutes.
- To serve, top with diced tomatoes.
- Enjoy!

Thanks for sharing. Love the Tillamook cheese factory. Have been there many times over the years.
Definitely a fun place to visit!
This sounds so good. I can’t wait to try it!
I make this but mix cream of celery or cream of mushroom in with my meat and later top with cheese. I add the sour cream as a garnish with the tomatoes and onions on top of each serving. Delish
Great ideas Dee!
I am allergic to sour cream.I sub usually miracle whip I,am wondering if that would work here. I am also allergic to ricotta. Do you have any suggestions? Thank you.
I think that would be your best option. If you see the original recipe link they do a mayo/sour cream mixture. So if you you use miracle whip I would cut back on the salt in that layer, taste it as you add it. 🙂
I’m thinking of throwing in some rotel tomatoes!
That sounds like an awesome idea. I’ll try that next time.
I’ll try this! I make a tater tot casserole in the oven! This would be much easier to manage!
I have never, ever, ever bought/eaten tater tots. Not my thing. I might try another posts suggestion of corn chips instead of the tater tots or maybe hash browns?
I bet this would be delicious with corn chips instead of tater tots for a crunch! But this sounds delicious! Will be making it soon! Thanks.
I was wondering if this could be done in the oven? Would the taste be the same? otherwise i think i have enough time to throw it in the crock pot now 🙂
I think it would taste great by cooking in the oven. I haven’t done it in the oven before, so I don’t have the time or temperature info.
Could I substitute the sour cream with plain nonfat Greek yogurt?
I’ve tried a few slow cooker recipes with nonfat Greek yogurt, it tends to melt and disappear. I think light or nonfat sour cream would hold up better.
Good to know about the greek yogurt, I like fatfree sourcream, have used it for years in the slow cooker.
