Ingredients You’ll Need

(6-quart slow cooker)
2 lbs (900g) baby potatoes, halved (Yukon Gold or red)
½ cup (1 stick / 115g) unsalted butter, cut into small pieces
1 large yellow onion, thinly sliced
1 tsp garlic powder (or 2 cloves minced garlic)
1 tsp dried thyme or rosemary
Salt & black pepper to taste
Optional: ¼ cup chicken broth (for extra moisture)

Pro Tips:
Don’t peel potatoes—skin adds flavor and holds shape.
Layer onions on bottom—they form a natural “bed” that prevents sticking.
Use real butter—margarine won’t give the same richness.

 

Step-by-Step Instructions (Tender, Buttery, Foolproof)

1. Layer in Slow Cooker
Place sliced onions in the bottom of the slow cooker.
Add potato halves on top.
Sprinkle with garlic powder, thyme, salt, and pepper.
Dot evenly with butter pieces.
Optional: Pour ¼ cup chicken broth around edges for extra sauciness.
2. Cook Low & Slow
Cover and cook on LOW for 5–6 hours (or HIGH for 3–4 hours), until potatoes are tender when pierced with a fork.
3. Finish & Serve
Gently stir to coat potatoes in the buttery onion sauce.
Taste—adjust salt and pepper if needed.
Optional: Garnish with fresh parsley or a sprinkle of Parmesan.
