Ingredients

- Fresh Green Beans: Cleaned and trimmed, these add the right amount of freshness to the dish.
- Yellow Onion: For an added depth of flavor!
- Cajun Seasoning: This is key for that bold Southern flavor.
- Spices: Along with the Cajun seasoning, all you need is salt, pepper and garlic powder!

How To Make Crock Pot Sausage Potatoes and Green Beans
✱ Be sure to see the recipe card below for exact ingredients and full recipe instructions!
Step 1 | Sear the Sausage
In a large skillet, sauté sliced smoked sausage until golden brown and extra flavorful. This is optional, but I recommend it!
Step 2 | Add Potatoes, Sausage & Onion to the Crock Pot
Place potatoes in the bottom of the slow cooker. Add sausage on top of the potatoes. Then add diced onion.
Step 3 | Add Green Beans & Spices
Add the green beans and sprinkle with seasoning, black pepper, garlic powder, and salt if using.
Step 4 | Toss
Toss everything together.
Step 5 | Top with Butter & Cook
Place sliced pats of butter all over the top. Cover the slow cooker with the lid and cook on low for 6-7 hours or on high for 3-4 hours, until the potatoes are tender.
Step 6 | Serve & Enjoy
Serve and enjoy!
Easy Variations
- Use canned green beans instead of fresh: Swap in 3 to 4 cans of drained green beans for convenience. Just note they’ll be softer in texture.
- Swap potatoes for what you have: Regular potatoes work just fine, just cut them into quarters so they cook evenly.
- Change up the seasoning: Not a fan of Cajun? Try a packet of onion soup mix or ranch seasoning for a different flavor twist.
- Add extra veggies: Carrots or bell peppers can be tossed in for added color and flavor.
- Use a different sausage: Kielbasa or turkey sausage both work great, depending on your preference.
Expert Tips
- Brown the sausage for extra flavor. While it’s optional, taking a few minutes to sauté the sausage adds a deeper, richer flavor. Those little caramelized edges really make a difference!
- Cut ingredients evenly. Try to keep your potatoes and green beans similar in size so they cook at the same rate. This prevents some pieces from getting too soft while others are still firm.
- Don’t skip the butter. The butter melts down and creates a rich, flavorful base that coats everything. It’s what gives this dish that classic, comforting taste of swamp potatoes!
- Be careful with adding too much salt. Cajun seasoning can vary in saltiness, so taste and adjust as needed. Start light, then add more if needed once everything is cooked.
What to Serve With Swap Potatoes
These slow cooker sausage, potatoes, and green beans are a full meal on their own (which is why I love it so much!). If you are feeding a crowd or just want some sides, it would go great with Southern favorites like Skillet Cornbread, fresh Coleslaw, or a Broccoli Salad with Bacon!
Storage & Make-Ahead Tips
Storage: Store any leftover swamp potatoes in an airtight container in the fridge for up to 4 days.
Freeze: Let cool completely, then freeze for up to 2 months. Thaw overnight in the fridge before reheating.
Make Ahead: To make ahead, prep all ingredients the night before and store them in the fridge, then dump everything into the slow cooker in the morning!
Recipe FAQs
