Creating your Crockpot Hamburger Potato Casserole is easy if you follow these simple steps:

1. Brown the Beef: In a skillet over medium heat, brown the ground beef and drain any excess fat.

2. Prepare the Crockpot: Lightly grease the inside of the crockpot for easier cleanup.

3. Layer the Ingredients: Start by adding half the sliced potatoes to the bottom of the crockpot. Then, layer half the diced onion, followed by half the browned beef.

4. Cheese Layer: Sprinkle half of the shredded cheddar cheese over the beef.

5. Repeat Layers: Repeat the layers with the remaining potatoes, onions, and beef, finishing with the rest of the cheese.

6. Mix the Sauce: In a medium bowl, combine the cream of mushroom soup, milk, garlic powder, salt, and pepper. Stir until smooth.

7. Pour Over Layers: Pour the mixture evenly over the layered ingredients in the crockpot. If using, add mixed vegetables on top for extra nutrients.

8. Cook: Cover the crockpot and set it to cook on low for 6-8 hours or high for 3-4 hours.

9. Serve Hot: Once the potatoes are tender, give it a good stir to combine the flavors.

10. Enjoy: Serve hot and savor the rich, comforting flavors of your casserole!
