Here's what you'll need for the Ultimate Slow Cooker Casserole:

1.5 pounds of your choice of ground protein (beef is our go-to, but pick what you like!)

1 onion, thinly sliced

4 potatoes, diced or sliced as you prefer

2 cups of chopped carrots

1 cup of chopped celery

3 garlic cloves, minced

A dash of olive oil

A sprinkle of onion powder

A dollop of A1 Sauce for that umami kick

A few slices of butter

1/2 cup of white rice, uncooked

A generous pour of water (1.5 cups)

A heaping of shredded cheddar cheese (1.5 cups)

1 can (10 ounces) of condensed tomato soup

A pinch of salt for seasoning

The magic happens in these simple steps:

Begin with a slow cooker canvas of onions, potatoes, carrots, celery, and garlic.

Brown your chosen protein in a skillet with a bit of olive oil. Season with salt, A1 sauce, and onion powder for that perfect flavor profile. Drain any excess fat away.

Layer the browned protein atop the veggies waiting in the slow cooker.

Dot the ensemble with butter, then sprinkle the uncooked rice over it.

Create a rich blanket with the tomato soup and water, pouring it evenly over the top.

Seal the deal with the slow cooker lid and let it cook on low for 6-8 hours, or on high for 4 hours, until the vegetables cuddle up to the tender rice.

Finishing touch: a cascade of cheddar cheese over the hot casserole. Give it a brief rest under the lid until the cheese is perfectly melted.

Serve your Slow Cooker Casserole hot from the pot and bask in the flavors of a meal that's as resourceful as it is delightful. Remember, this recipe is all about making it yours, so tweak, substitute, and experiment to your heart's content!
