4-Ingredient Slow Cooker Flag Day Potatoes
This 4-ingredient slow cooker flag day potatoes recipe is my kind of busy-day cooking: toss raw, unpeeled whole russet potatoes into the slow cooker with just three pantry staples, turn it on, and come home to a cozy, buttery, garlicky side dish that tastes like you spent far more time on it than you actually did.
I first started making these potatoes during summer flag holidays when I wanted to avoid heating up the kitchen with the oven. Before long, they became a year-round favorite for busy evenings when I still wanted a comforting, homemade side dish on the table.
The potatoes cook until perfectly tender and soak up all the buttery seasoning. Serve them whole or gently smash them in the slow cooker so the flavorful butter seeps into every bite.

Servings
6 servings
Ingredients
- 3 pounds small to medium russet potatoes, scrubbed well and left whole
- 4 tablespoons unsalted butter, cut into small pieces
- 1½ teaspoons kosher salt (or 1 teaspoon table salt)
- 1 teaspoon garlic powder or granulated garlic
Directions
Step 1: Clean the Potatoes
Scrub the potatoes thoroughly under cool running water to remove any dirt from the skins.
Leave the potatoes whole and unpeeled. Pat dry with a clean kitchen towel.
Step 2: Arrange in the Slow Cooker
Place the potatoes in a single snug layer in the bottom of a 4- to 6-quart slow cooker.
If necessary, stack a few potatoes on top, but keep most of them touching the bottom for even cooking.
Step 3: Add the Seasonings
Sprinkle the salt and garlic powder evenly over the potatoes.
Scatter the butter pieces over and around the potatoes so they melt evenly during cooking.
Step 4: Slow Cook
Cover with the lid and cook:
- HIGH: 3½ to 4½ hours
- LOW: 6 to 7 hours
The potatoes are ready when they can easily be pierced with a fork or skewer.
Step 5: Coat the Potatoes
Once tender, use tongs to gently roll the potatoes through the melted butter and seasonings collected at the bottom of the slow cooker.
This coats the skins with extra flavor and gives the potatoes a glossy finish.
Step 6: Optional Smash
For extra flavor, gently press each potato with the back of a spoon or fork.
This cracks the skins slightly and allows the buttery garlic mixture to soak into the centers.
Step 7: Serve
Taste and add a little more salt if desired.
Serve hot, spooning the buttery garlic mixture over each portion.
If serving over an extended period, keep the slow cooker on the WARM setting.
Variations & Tips
- Add 1 teaspoon dried Italian seasoning or parsley for an herb-flavored version.
- Mix in 1/2 teaspoon smoked paprika for a subtle smoky flavor.
- Sprinkle 1 to 1½ cups shredded cheddar or Monterey Jack cheese over the cooked potatoes and allow it to melt before serving.
- Top with sour cream, Greek yogurt, bacon crumbles, or green onions.
- Replace half of the butter with olive oil for a lighter version.
- Lightly smash the potatoes before serving to absorb more butter and seasoning.
