How to Make Slow Cooker Buttery Potatoes and Sweet Onions
Step 1: Prepare the Vegetables
Wash the potatoes thoroughly and cut them into evenly sized chunks. Peel the onions and slice them thinly so they soften evenly during cooking.
Step 2: Layer the Potatoes and Onions
Lightly grease the slow cooker if desired. Add the potatoes and sliced onions, spreading them into an even layer. Sprinkle with salt and black pepper.
Step 3: Add the Butter and Broth
Scatter the butter pieces over the potatoes and onions. Pour the broth around the vegetables to provide moisture and help prevent the bottom from drying out.
Step 4: Slow Cook Until Tender
Cover and cook on LOW for approximately 4–6 hours or on HIGH for 2–3 hours. Cooking times depend on the size of the potato pieces and your slow cooker.
Check the potatoes with a fork near the end of cooking. They should be soft and tender without falling apart. Avoid stirring too frequently, as the potatoes can break into smaller pieces.
Step 5: Toss and Serve
Gently stir the potatoes and onions so they are coated in the melted butter and flavorful cooking juices. Taste and adjust the seasoning if needed.
Serve warm, spooning the buttery onions and juices over the potatoes for extra flavor.
Helpful Tips for the Best Results
- Choose the right potatoes: Yukon Gold potatoes have a naturally creamy texture, while red potatoes tend to hold their shape well.
- Cut evenly: Similar-sized potato pieces cook more consistently.
- Slice the onions thinly: This helps them soften and develop a sweeter flavor.
- Don’t add too much liquid: The goal is tender potatoes coated in buttery juices, not watery potatoes.
- Keep the lid closed: Opening it too often releases heat and may increase cooking time.
What to Serve with Buttery Potatoes and Onions
These potatoes are a wonderful side dish for roasted chicken, slow cooker beef roast, pork chops, meatloaf, or grilled sausages. They also pair well with green beans, steamed broccoli, or a fresh salad.
For a comforting family dinner, serve a generous portion alongside your favorite main dish and spoon the sweet onions and buttery juices over the top.
Leftovers and Storage
Allow leftovers to cool slightly and refrigerate them in an airtight container within two hours of cooking. Store in the refrigerator for 3–4 days.
Reheat in a covered skillet or microwave until heated through. Add a small splash of broth or a little butter if the potatoes seem dry. You can freeze leftovers, although the potatoes may become softer after thawing.
