This dish takes the humble potato and transforms it into a melt-in-your-mouth side dish. By layering sliced gold potatoes with plenty of onions and a touch of butter, the slow cooker mimics the deep, savory flavors of a long roast without you having to hover over a hot stove.
Meta Description: Master the art of effortless side dishes with this Slow Cooker Sliced Potatoes and Onions recipe. Perfectly tender, buttery, and infused with savory caramelized onions.
Recipe Overview
- Prep time: 15 minutes
- Cook time: 4–5 hours (High) or 7–8 hours (Low)
- Servings: 6
- Difficulty: Easy
Ingredients
- Potatoes: 3 lbs Yukon Gold or Red potatoes (scrubbed and sliced into 1/4-inch rounds)
- Onions: 2 large yellow onions (thinly sliced)
- Butter: 1/2 cup (1 stick) unsalted butter, melted
- Garlic: 3 cloves, minced
- Seasonings: 1 tsp salt, 1/2 tsp black pepper, 1 tsp dried thyme (or rosemary)
- Liquid: 1/4 cup chicken or vegetable broth (prevents sticking and adds steam)
- Optional: Fresh parsley for garnish
Step-by-Step Instructions
- Prep the Crockpot: Grease the inside of a 6-quart slow cooker with cooking spray or a light coating of butter to prevent sticking.
- Seasoning Mix: In a small bowl, whisk together the melted butter, minced garlic, salt, pepper, and dried herbs.
- Layering: Place a layer of sliced potatoes at the bottom of the slow cooker. Top with a handful of sliced onions. Drizzle a small amount of the butter mixture over the layer. Repeat until all potatoes and onions are used.
- Add Liquid: Pour the broth around the edges of the pot. Drizzle any remaining butter mixture over the very top layer.
- Slow Cook: Cover and cook on High for 4–5 hours or Low for 7–8 hours. The potatoes are done when they are fork-tender and the onions have turned translucent and golden.
- The Finishing Touch: For a bit of extra color, you can carefully transfer the potatoes to a baking sheet and broil for 3–5 minutes, though they are delicious straight from the pot!
Service Suggestions
- The Main Event: Pair these with a juicy roast chicken, grilled steak, or a festive pork loin.
- Brunch Style: Serve alongside over-easy eggs and crispy bacon.
- Toppings: A dollop of sour cream or a sprinkle of sharp cheddar cheese right before serving adds a nice richness.
Storage Tips
- Refrigerate: Store leftovers in an airtight container for up to 4 days.
- Reheat: For best results, reheat in a skillet with a tiny bit of butter to regain some texture, or microwave in 30-second intervals.
- Freezing: I don’t recommend freezing this dish, as the texture of cooked potatoes often becomes grainy once thawed.
FAQs
Do I need to peel the potatoes?
Not necessarily! Yukon Gold and Red potatoes have thin skins that soften beautifully. If using Russets, you may want to peel them as their skin can be a bit tough.
Can I add meat to this?
Absolutely. Adding chopped bacon or sliced smoked sausage between the layers turns this side dish into a full, hearty meal.
Why are my potatoes turning grey?
Potatoes can discolor if they sit out sliced for too long before cooking. Keep them in a bowl of cold water while you prep, then pat them dry before layering.
Conclusion
There is something incredibly comforting about the combination of butter, onions, and potatoes. This slow cooker method is the ultimate “set it and forget it” solution for busy weeknights or holiday dinners when oven space is at a premium. Simple, rustic, and consistently delicious!
