How to Make Crockpot Swamp Potatoes
Prep
- Cut the potatoes into bite-sized pieces (not too small).
- Chop the onion.
- Trim and cut the green beans into 2-inch pieces.

- Sprinkle the onion soup mix over the sausage.
- Place the stick of butter on top.
- Pour in the chicken broth.
Slow Cook
- Cover and cook on Low for 5–6 hours or High for 3–4 hours, until potatoes and onions are tender.
- Stir once halfway through and again about 30 minutes before serving.
Recipe Tips
- Extra broth: Add more chicken broth if you want additional “potlikker” (flavorful cooking liquid).
- Spice level: Adjust Cajun seasoning to your heat preference (or use red pepper flakes for less salt).
- Make ahead: Prep the potatoes, onion, and sausage the night before for faster assembly.
Storage and Reheating
- Store: Keep leftover Crockpot Swamp Potatoes in an airtight container in the fridge for up to 4 days.
- Freeze: Freeze for up to 2 months (potatoes and beans may soften). Thaw in the fridge overnight.

Nutrition

I’m interested in making this oil-free, plant-based. Omitting the sausage, oil & butter. Thoughts?
Use veggie broth, maybe add carrots, and your favorite meat substitute. I’m not real familiar with them, but maybe Impossible meatballs, if they make them?If you are not going for completely fat-free, you could try coconut oil.
