This hearty one-pot meal combines tender potatoes, smoked sausage, green beans, onions, butter, and savory onion soup mix in the slow cooker for an easy dinner your whole family will love. It’s inexpensive, filling, and practically cooks itself!

The Easiest One-Pot Meal You’ll Make All Week

Every once in a while I stumble across a recipe that makes me wonder, “Where has this been all my life?”

That’s exactly how I felt after making these Slow Cooker Swamp Potatoes.

The ingredient list couldn’t be simpler: potatoes, smoked sausage, canned green beans, onions, butter, garlic, and a packet of onion soup mix. Toss everything into the slow cooker before you head out for the day, and by dinnertime you’ve got a hearty meal waiting for you.

I wasn’t entirely sure about that packet of onion soup mix. It seemed like an unusual ingredient, but after one bite I understood exactly why it’s there. It seasons the entire dish, creating a rich, savory broth that soaks into the potatoes and even flavors the sausage.

Speaking of the sausage…

That may have been my favorite part.

Because smoked sausage is already fully cooked, all I had to do was slice it into rounds and toss it into the crock pot. As it simmered with the potatoes and green beans, it absorbed all of those buttery, savory flavors and became unbelievably tender and juicy.

This is one of those true dump-and-go recipes. No browning meat. No frying bacon. No standing over the stove. Just chop, dump, and let the slow cooker do the work.

Even better? This isn’t just a side dish.

It’s dinner.

Why You’ll Love This Recipe

If you enjoy my How to Make Canned Green Beans Taste Homemade recipe, you’ll recognize some familiar flavors here. Both recipes transform ordinary canned green beans into something special.

The difference? This one is a complete meal. Between the potatoes, smoked sausage, onions, and green beans, you’ve got everything you need in one pot. Add a piece of cornbread or a warm biscuit if you’d like, but honestly, a bowl and a fork are all you really need.

It’s also one of the most budget-friendly meals I’ve made lately. A few inexpensive ingredients feed several people, making this a wonderful choice for busy families, meal prep, or taking dinner to a friend.

In fact, I packed up a container while it was still hot from the slow cooker and met some friends to pass it along. They couldn’t even wait to get home before tasting it! After a few bites they were already telling me how much they loved it, and after eating a bowl myself, I completely understood why.

Ingredients

You will find a full printable recipe card at the bottom of this post, friends. But here’s a quick look at what you will need. These are such simple ingredients. You might already have them in your kitchen.

• 3 pounds russet potatoes, scrubbed and cut into 1-inch chunks (leave the skins on)
• 1 large yellow onion, diced
• 1 package (13–14 ounces) smoked sausage or kielbasa, sliced into rounds
• 2 large cans cut green beans, drain about half the liquid
• 1 packet Lipton Onion Soup Mix
• 2 teaspoons minced garlic
• 1 teaspoon black pepper
• ½ teaspoon garlic powder
• ½ teaspoon smoked paprika (optional)
• 1 stick (½ cup) butter, sliced into pats

Optional

• Pinch of cayenne pepper
• Chopped parsley for garnish

How to Make Slow Cooker Swamp Potatoes

Step One

Wash the potatoes and cut them into bite-sized chunks. Dice the onion and slice the smoked sausage.

Step Two

Spray a 6- or 7-quart slow cooker with nonstick spray. Add the potatoes, onions, sausage, and green beans. Sprinkle the onion soup mix, garlic, black pepper, garlic powder, and smoked paprika evenly over the top. Mix well.

Arrange the pats of butter across the surface.

Step Three

Cover and cook on HIGH for about 2 hours, then reduce the heat to LOW for another 2 hours, or until the potatoes are fork tender. (Cooking times may vary slightly depending on your slow cooker.)

Give everything a gentle stir before serving.

Store leftovers in an airtight container in the refrigerator for up to 4 days.

To reheat: Microwave individual servings until hot. For larger portions, reheat gently on the stovetop over medium-low heat, adding a splash of chicken broth if needed.

What to Expect

As the potatoes cook, they absorb the buttery broth created by the green bean liquid, melted butter, onions, and onion soup mix.

One of the biggest surprises for me was the smoked sausage. Instead of drying out, it became incredibly juicy and flavorful as it soaked up all those wonderful seasonings.

Every bite is loaded with tender potatoes, savory sausage, sweet onions, and perfectly seasoned green beans.

It’s simple comfort food at its best.
