This 4-ingredient slow cooker Irish cheddar potato recipe is exactly the kind of dish that disappears before you can even grab seconds. I made it for our St. Patrick’s Day dinner one year, and my sister-in-law immediately begged me for the recipe after scraping the last cheesy bits from the slow cooker. It’s creamy, buttery, and feels like a cozy hug in a bowl—no fussy roux, no canned soup, just simple Yukon gold potatoes, real Irish-style cheddar, and butter doing their thing low and slow. It’s perfect for busy weeknights or holidays when you want something that tastes special but doesn’t keep you tied to the stove.
Serve these creamy Irish cheddar potatoes straight from the slow cooker with a big spoon for scooping. They’re perfect alongside corned beef, roast chicken, grilled sausages, or a simple green salad. Add a side of steamed green beans or roasted carrots to balance the richness, and some crusty bread to swipe up the buttery cheese sauce. For St. Patrick’s Day, pair with soda bread and a pint of your favorite Irish stout or a crisp hard cider for a cozy, pub-style meal at home.
Slow Cooker Irish Cheddar Yukon Gold PotatoesServings: 6
Ingredients
3 pounds Yukon Gold potatoes, thinly sliced (about 1/8–1/4 inch thick)
8 ounces Irish cheddar cheese, shredded (about 2 cups packed)
1/2 cup (1 stick) unsalted butter, thinly sliced
1 cup heavy cream
1 teaspoon kosher salt (optional, to taste)
1/2 teaspoon freshly ground black pepper (optional, to taste)
Nonstick cooking spray or a little butter for greasing the slow cooker
Directions
Lightly grease the inside of a 4- to 6-quart slow cooker with nonstick cooking spray or a little butter to help prevent sticking and make cleanup easier.
Wash the Yukon Gold potatoes and pat them dry. Leaving the skins on for extra texture and flavor, thinly slice them into rounds about 1/8–1/4 inch thick. A mandoline makes this fast, but a sharp knife works just fine.
In a small bowl or measuring cup, whisk together the heavy cream, salt, and black pepper (if using). This seasoned cream will soak into the potatoes and help create that rich, creamy sauce.
Layer about one-third of the sliced potatoes evenly in the bottom of the slow cooker, overlapping slightly like shingles so they cook evenly.
Sprinkle about one-third of the shredded Irish cheddar over the potatoes, then dot with one-third of the butter slices. This layering is what gives you those pockets of melty, stretchy cheese in every scoop.
Repeat the layers two more times: potatoes, then cheddar, then butter, ending with a final layer of cheese and butter on top.
Slowly pour the seasoned heavy cream evenly over the layered potatoes and cheese, letting it seep down between the slices. Gently press the top layer down with a spoon to help everything settle.
Cover the slow cooker with the lid and cook on LOW for 4–5 hours, or on HIGH for 2–3 hours, until the potatoes are very tender when pierced with a fork and the edges are bubbling and golden.
Once cooked, turn the slow cooker to WARM and let the potatoes sit, covered, for about 10–15 minutes. This rest time helps the cheesy, buttery cream thicken into a silky sauce that clings to the potatoes.
Right before serving, gently stir just the top layer to reveal some of the melty cheese underneath while still keeping some layers intact. Use a large serving spoon to scoop, making sure each serving gets plenty of creamy sauce and stretchy cheese. Serve straight from the slow cooker while hot.
Variations & Tips
For extra flavor without adding more ingredients, try using a sharp or extra-sharp Irish cheddar so the cheese really stands out against the rich potatoes. If you like a little color, you can quickly broil the finished potatoes: transfer them to an oven-safe dish, top with a bit more shredded cheddar, and broil for a few minutes until browned and bubbly. To lighten things up slightly, use half-and-half instead of heavy cream and reduce the butter to 6 tablespoons, knowing the sauce will be a bit less thick but still comforting. For make-ahead prep on a busy day, slice the potatoes and shred the cheese the night before, storing each separately in airtight containers in the fridge; then just layer everything into the slow cooker in the morning. If your slow cooker runs hot and you notice too much browning on the edges, stir gently halfway through and add a splash more cream. Leftovers reheat well in the microwave or in a covered dish in the oven with a spoonful of cream to bring back the silky texture.
