Start by halving the small baby potatoes and slicing the smoky sausage into bite-sized pieces. Trim the ends off the green beans if using fresh ones. Next, add all these ingredients into a 6-quart slow cooker, arranging them evenly to ensure even cooking.

Sprinkle the ranch seasoning mix and Cajun seasoning evenly over the assembled potatoes, sausage, and green beans in the slow cooker. Use your hands to gently toss the ingredients, making sure the seasonings coat everything well and infuse maximum flavor.

Pour one cup of beef broth over the mixture, ensuring it seeps down through the layers of ingredients. Stir thoroughly to combine everything nicely.

Distribute the six tablespoons of butter in even pats atop the mixture. This will melt and enrich the dish.

Cover the slow cooker and set it to cook on LOW for 6 to 8 hours or on HIGH for 3 to 4 hours until potatoes are fork-tender and green beans are slightly crisp.

Once cooked, give the easy slow cooker swamp potatoes a gentle stir to mix the ingredients before serving.
