It is absolutely perfect for Easter Sunday, holiday dinners, or any busy weeknight!
Why You’ll Love This Recipe
- Only 4 Ingredients: You just need red potatoes, sour cream, salted butter, and salt!
- Zero Peeling Required: Leaving the red skins on gives the dish a beautiful, rustic farmhouse feel and saves you tons of prep time.
- The Perfect Texture: As you stir the finished dish, some of the tender potatoes naturally break apart, perfectly thickening the buttery cream sauce.
- Make-Ahead Friendly: You can prep all the ingredients the night before so you just have to toss them in the crockpot on your way out the door.
What You’ll Need
To get the most even cook, make sure your potatoes are roughly the same size! If you have any jumbo baby potatoes in the bag, just slice them in half.
- 2 ½ lbs Baby red potatoes: Unpeeled and left whole (or halved if larger).
- 1 cup Sour cream: The tangy, rich base for your creamy sauce.
- ½ cup (1 stick) Salted butter: Cut into small cubes so it melts evenly over the potatoes.
- 1 ½ tsp Salt: Plus a little extra to taste at the very end!
How to Make It (Step-by-Step)
Prep time: 10 minutes | Cook time: 2–5 hours | Total time: approx. 2.5–5 hours | Yield: 6 Servings
Step 1: Prep the Crock
Lightly grease a 4- to 6-quart slow cooker with nonstick spray or a little smear of butter to help with cleanup later.
Step 2: Wash the Potatoes
Rinse the baby red potatoes thoroughly under cold water and pat them completely dry. Leave the skins on! If any potatoes are much larger than the others, cut them in half so they cook at the exact same rate.
Step 3: The Base Layer
Place the raw baby red potatoes in an even layer right in the bottom of your greased slow cooker.
Step 4: The Creamy Dollops
In a small bowl, stir together the 1 cup of sour cream and the 1 ½ teaspoons of salt until the salt is evenly distributed. Drop spoonfuls of this sour cream mixture directly over and around the potatoes, letting some of it fall down into the gaps.
Step 5: Add the Butter
Scatter the small pieces of salted butter evenly over the top of the potatoes and the sour cream dollops.
Step 6: Low and Slow
Cover the slow cooker tightly with the lid. Cook on LOW for 4 to 5 hours, or on HIGH for 2 to 3 hours, until the potatoes are very tender when pierced with a fork.
Step 7: Stir and Smash
Once the potatoes are tender, use a large spoon to gently stir from the bottom of the slow cooker, coating the potatoes in the buttery, creamy mixture.
💡 Crucial Step: Let a few of the potatoes break apart as you stir! The starches from the broken potatoes will mix with the butter and sour cream, thickening it into that signature, cozy Amish-style sauce.
Step 8: Taste and Serve
Taste the creamy sauce and add a pinch more salt if needed. Switch the slow cooker to the WARM setting and keep it covered until you are ready to serve!
💡 Expert Tips for Success
- Dry the Potatoes: Don’t skip patting the washed potatoes dry in Step 2. Excess water on the skins will water down your rich, creamy sauce!
- The Pantry Upgrade: If you want a little extra flavor without technically adding more “core” ingredients, add a few generous grinds of black pepper or a pinch of garlic powder to the sour cream before dolloping it over the potatoes.
- The Morning-Rush Hack: You can wash and dry the potatoes, cut the butter, and mix the sour cream and salt the night before. Store everything in the fridge, then in the morning, just dump it all into the slow cooker and turn it on!
Variations and Substitutions
- The Greek Yogurt Swap: If you prefer a tangier, slightly lighter version with a bit more protein, swap half (or all) of the sour cream for plain, full-fat Greek yogurt.
- The Meaty Addition: To make this more of a complete, one-pot meal, stir in a cup of cooked, diced ham or crumbled bacon during the last 30 minutes of cooking so it warms through without getting soggy.
- The Cheesy Crust: If your family loves cheese, sprinkle a massive handful of shredded cheddar or Colby Jack over the top of the potatoes during the last 10 minutes on HIGH. Cover and let it melt into a gooey crust!
Serving Suggestions
- The Holiday Spread: Serve these rustic potatoes right out of the slow cooker alongside a honey-glazed ham, a whole roasted chicken, or a classic Sunday pot roast.
- The Weeknight Main: They pair beautifully with simple, savory weeknight mains like grilled sausages, pan-seared pork chops, or baked salmon.
- The Bread Basket: Because the creamy sauce is so incredibly rich and delicious, you absolutely need to serve this with crusty French bread or warm dinner rolls to soak up the bottom of your bowl!
