4-Ingredient Slow Cooker Sausage, Potato & Green Bean Casserole
Servings: 4–6 servings
Ingredients
| Ingredient | Quantity |
|---|---|
| Smoked sausage or kielbasa, sliced into 1/2-inch rounds | 1 to 1 1/2 pounds |
| Potatoes, scrubbed and cut into 1-inch chunks (Yukon Gold or russet) | 2 pounds |
| Fresh green beans, trimmed and cut into 2-inch pieces | 1 to 1 1/2 pounds |
| Cream of mushroom soup (or cream of chicken), undiluted | 1 (10.5-ounce) can |
| Salt and black pepper (optional) | To taste |
| Water or chicken broth (optional, for extra sauce) | 1/2 cup |

Instructions
Slice the smoked sausage into rounds, scrub the potatoes, and cut them into evenly sized chunks. Trim the green beans, remove the ends, and break them into 2-inch pieces. Lightly grease the inside of a 4- to 6-quart slow cooker. Arrange the potatoes in an even layer on the bottom, spread the green beans over the top, and finish with the sliced sausage. Spoon the cream of mushroom soup over everything. If you prefer more sauce, pour up to 1/2 cup of water or chicken broth around the edges. Use a spoon to gently spread the soup over the ingredients. Season lightly with salt and black pepper if desired, keeping in mind that the sausage adds saltiness. Cover and cook on LOW for 6–8 hours or on HIGH for 3–4 hours, until the potatoes are fork-tender and the green beans are soft but not overcooked. Before serving, gently stir from the bottom to evenly coat everything in the sauce. Taste and adjust seasoning if needed, then serve hot directly from the slow cooker.
Variations & Tips
This recipe is easy to customize while keeping its comforting, rustic character. For a deeper smoky taste, use extra-smoked kielbasa or top servings with crispy bacon bits. Add sliced onion or baby carrots if you want more color and natural sweetness. For a lighter twist, swap in turkey sausage and cream of chicken soup. Frozen green beans can replace fresh ones when needed—just allow a little extra cooking time on LOW. If you like more flavor depth, mix in Italian seasoning or a pinch of red pepper flakes with the soup. For extra creaminess, sprinkle shredded cheddar or Colby-Jack over the top during the final 15 minutes of cooking until melted. This forgiving, pantry-friendly dish works well with whatever potatoes or sausage you have on hand, making it ideal for practical, home-style cooking.
