This comforting Cowboy Casserole is a budget friendly one-dish meal that is great for the whole family. With ground beef, black beans, pinto beans, and corn, with a creamy tomato sauce, lots of cheese, and topped with crispy tater tots, it’s the ultimate comfort food but is also nutritious.

What is Cowboy Casserole?
The basic components of Cowboy Casserole dishes are ground beef and corn in a creamy sauce, with a single layer of tater tots and cheese on top. This recipe is more healthy and filling with lower fat from lean minced beef, added protein in the mixed beans and antioxidants from cooked tomatoes.
You can add more chopped vegetables to the dish or serve it with vegetable side dishes like green beans or broccoli grape salad for a fuller meal, or if you want it to serve more people.
This tater tot casserole is great for busy weeknights as it only takes 10 minutes of prep and 30 minutes of cooking time in the oven. You can even make this dish up to 24 hours ahead of time and keep it refrigerated until you’re ready to bake it!
We love no-fuss, hearty meals, that are also budget friendly like this one because they’re so handy when you need a quick but tasty meal for the whole family!
Our Chicken Casserole takes just 40 minutes and freezes really well so is great for meal prepping too. This filling Goulash is ready in less than 30 minutes and tastes great with classic Cornbread. Also, try my Cowboy Soup for similar hearty Tex-Mex flavors!

Ingredients Needed
Ground Beef – Use lean ground beef. You can also use turkey or ground pork.

Can I make it ahead of time?
Yes, you can! Cowboy Casserole is great because you can prep it up to a day ahead of time. Just assemble it, cover the dish tightly with plastic wrap and it will keep well in the refrigerator for up to 24 hours.
Then just take it from the refrigerator, remove the plastic wrap and bake as per the recipe instructions. Perfect for potlucks or Sunday prep for an easy Monday meal!

How to serve and store Cowboy Casserole
Cowboy casserole is best served immediately after baking, and this recipe makes a heartier version with added beans. However, if you want a fuller meal, or want to make this casserole recipe stretch to serve more people, serve with some green vegetables like green beans or a salad.
- Countertop: You can have the casserole at room temperature for up to 2 hours.
- Refrigerator: Put leftovers in an airtight container, or cover in plastic wrap, and keep in the refrigerator for up to 4 days.
Can I freeze it?
A baked cowboy casserole will store well in the freezer wrapped tightly in plastic wrap or foil, or in an airtight container, for up to 3 months. To cook it from frozen, allow it to thaw in the refrigerator overnight and bake as per this recipe.
You may want to put some foil on top of your dish for the first half of baking, especially if it was particularly brown on top when baked the first time to make sure it doesn’t burn.
Can I make it in a slow cooker?
To make Cowboy Casserole in the slow cooker simply follow the directions as they are, place everything in the slow cooker instead of a baking dish, and then cook on low for 5 hours.
For best results, don’t lift the lid until the time is finished.

Tips for No Leftovers
