Creating the Slow Cooker Cowboy Potato Casserole is simple if you follow these easy steps:

1. Cook the Meat: In a skillet over medium heat, cook the ground beef or turkey until browned. Drain any excess fat.
2. Prepare the Potatoes: Peel and dice the russet potatoes into bite-sized pieces. Place them in a large bowl.
3. Mix Ingredients: In another bowl, combine the cream of chicken soup, sour cream, milk, ranch seasoning mix, garlic powder, black pepper, and salt. Mix well to blend.
4. Layer the Slow Cooker: Start by layering half of the diced potatoes in the slow cooker. Follow with half of the cooked meat, crumbled bacon, and half of the cheese.
5. Add Additional Layers: Pour half of the creamy mixture over the layers. Repeat the process with the remaining potatoes, meat, bacon, and cheese, then finish with the rest of the creamy mixture on top.
6. Cook: Cover and cook on low for 6-7 hours or on high for 3-4 hours. Ensure the potatoes are tender when pierced with a fork.
7. Garnish and Serve: Once the casserole is fully cooked, turn off the slow cooker. Sprinkle with chopped green onions before serving for an extra pop of flavor and color.

These steps will allow you to create a mouthwatering casserole easily. The slow cooking process allows all the flavors to meld while you go about your day!
