This 5-ingredient slow cooker Father’s Day feast potatoes recipe is exactly what I reach for when I want something cozy and hands-off, but still special enough to celebrate my husband. You literally dump a bag of fresh fingerling potatoes into the crock, add just four pantry-friendly ingredients, flip the switch, and walk away. A few hours later, you’ve got tender, buttery, garlicky potatoes with crispy edges that taste like you fussed way more than you actually did. It’s perfect for busy weekends, backyard grilling nights, or any time you want a savory side that practically makes itself while you focus on everything else.
These slow cooker fingerling potatoes are made for cookouts and family dinners. Serve them alongside grilled steak, burgers, brats, or roasted chicken, and add a simple green salad or steamed veggies to round out the plate. They’re also great with eggs the next morning as a quick breakfast hash—just reheat in a skillet to crisp them back up. A drizzle of extra melted butter or a spoonful of sour cream on top right before serving makes them feel extra indulgent for Father’s Day.
5-Ingredient Slow Cooker Father’s Day Feast PotatoesServings: 6
Ingredients
2 pounds fresh fingerling potatoes, rinsed and patted dry
3 tablespoons unsalted butter, melted (plus a little extra for drizzling, optional)
1 packet (1 ounce) dry onion soup mix
1 teaspoon garlic powder
1/2 teaspoon freshly ground black pepper
Directions
Lightly mist the inside of your slow cooker with cooking spray or brush with a tiny bit of melted butter to help prevent sticking and make cleanup easier.
Dump the rinsed and dried fingerling potatoes straight into the bottom of the slow cooker insert, spreading them into an even layer. The potatoes can overlap a bit, but you want them mostly in a single layer if possible.
In a small bowl, whisk together the melted butter, dry onion soup mix, garlic powder, and black pepper until the mixture looks like a loose paste or thick sauce.
Pour the butter and seasoning mixture evenly over the fingerling potatoes, using a spatula to scrape out every bit. Toss the potatoes gently right in the crock to coat them well, making sure the seasoning gets down between the potatoes.
Cover the slow cooker with the lid and 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. Avoid lifting the lid during the first 2 hours so the heat stays consistent.
Once the potatoes are tender, give them a gentle stir to redistribute the buttery seasoning. If you like them extra rich, drizzle with another tablespoon of melted butter and toss again.
Taste and adjust the seasoning if needed, adding a pinch more pepper or a small sprinkle of salt only if the onion soup mix you used is not very salty. Transfer the potatoes to a serving bowl and spoon any buttery juices from the bottom of the crock over the top before serving warm.
Variations & Tips
For a little color and freshness, sprinkle the finished potatoes with chopped fresh parsley or chives, especially if you’re serving them for a Father’s Day spread. If your family loves cheese, stir in 1/2 to 1 cup of shredded sharp cheddar or Parmesan during the last 15 minutes of cooking on LOW, then cover again just until melted. You can also swap the garlic powder for smoked paprika if you want a subtle smoky flavor to match grilled meats. For a lighter version, reduce the butter to 2 tablespoons and add 1 tablespoon of olive oil; the texture will still be rich without feeling quite as heavy. If you need to keep the dish warm for a party, switch the slow cooker to WARM once the potatoes are tender and hold for up to 1 hour, stirring occasionally so the edges don’t overcook. Food safety tips: Always start with fresh, firm fingerling potatoes—discard any that are soft, green, or sprouting heavily. Rinse and dry them well before cooking to remove dirt. Do not leave cooked potatoes sitting at room temperature for more than 2 hours; refrigerate leftovers in a shallow container within that time. Reheat leftovers to at least 165°F before serving, and use within 3 to 4 days for best quality.
