Why You’ll Love This Recipe
This dish stands out because it requires minimal effort but produces maximum flavor. The slow cooker does all the work, allowing the potatoes to absorb the buttery richness and sweet, caramelized notes of the onions. The result is tender, savory potatoes with a silky texture and a subtle depth that feels indulgent yet comforting.
Ingredients You’ll Need
- 1.5 kg (about 3 lbs) potatoes (Yukon Gold or baby potatoes work best)
- 1 large onion, thinly sliced
- 100 g (about 7 tbsp) unsalted butter, melted
- 2 cloves garlic, minced
- 1 tsp salt (adjust to taste)
- ½ tsp black pepper
- 1 tsp dried thyme (optional)
- 1 tsp paprika (optional, for warmth and color)
- Fresh parsley for garnish (optional)
Step-by-Step Method
1. Prepare the Potatoes
Start by washing your potatoes thoroughly. If you’re using baby potatoes, you can leave them whole or cut them in halves. For larger potatoes, peel them if desired and cut them into evenly sized chunks. Uniform size ensures even cooking.
2. Slice the Onion and Garlic
Thinly slice the onion so it cooks down smoothly and blends into the dish. Mince the garlic finely to distribute its flavor evenly throughout the potatoes.
3. Layer the Ingredients
Lightly grease your slow cooker to prevent sticking. Begin by placing a layer of potatoes at the bottom. Add a portion of the sliced onions and a sprinkle of garlic. Continue layering until all ingredients are used.
4. Add Butter and Seasoning
Pour the melted butter evenly over the layered potatoes and onions. Then sprinkle salt, pepper, thyme, and paprika across the top. The butter will seep down during cooking, coating everything in rich flavor.
