There are nights when everyone is hungry, the day has been long, and I just want dinner to feel comforting without making a mess of the kitchen. That is exactly when this cozy slow cooker cowboy casserole shows up for me. It is hearty, filling, and made with ingredients I almost always have on hand. Best of all, the slow cooker does most of the work.
The first time I made this, it was one of those busy afternoons where dinner needed to cook itself. I browned the beef, dumped everything into the slow cooker, and hoped for the best. A few hours later, the house smelled incredible, and dinner disappeared fast. That was all the proof I needed. This one went straight into the regular rotation.

Serving Ideas
This slow cooker cowboy casserole is a full meal on its own, but you can easily add a simple side.
I like serving it with a green salad to balance the richness. Cornbread or dinner rolls work well if you want something extra. A dollop of sour cream on top is always a hit, too.
Storage And Leftovers

Leftovers store well in the fridge for up to three days. Reheat in the microwave or on the stove until warmed through.
You can also freeze leftovers for up to two months. Let the casserole cool completely before freezing. Thaw overnight in the fridge and reheat gently.
FAQs
Yes. This is a great make ahead meal. You can prepare everything except the tater tots, refrigerate it, and start cooking when ready.
You can, but they add a lot of texture. If skipping them, serve the casserole with chips or bread on the side.
Very much so. You can control the spice by choosing mild taco seasoning.
