Ingredients
Russet Potatoes
Firm, starchy, and reliable, russet potatoes hold their shape beautifully during slow cooking. Choose smooth, unblemished ones with no green spots.
Garlic Powder
Adds gentle aromatic warmth without overpowering the onion flavor.
Black Pepper
Freshly ground black pepper deepens the savory notes and provides subtle heat.
Lipton Onion Soup Mix
This iconic ingredient gives the dish its signature taste—bold, nostalgic, and deeply comforting.
Olive Oil
Adds richness, helps the potatoes brown slightly on the edges, and keeps every slice moist. Use extra virgin olive oil for the best aroma and flavor.
Step-by-Step Instructions
Step 1: Prepare the Slow Cooker
Coat the inside of your slow cooker with nonstick spray or a little olive oil. This prevents sticking and makes cleanup effortless.
Step 2: Slice the Potatoes
Using a sharp knife or mandoline, slice the russet potatoes into thin rounds—about ⅛ inch thick. Even slices ensure they cook uniformly.
Step 3: Arrange in Layers
Layer the slices inside your slow cooker. You can spiral them for an elegant presentation or simply stack them in flat layers—either way, they’ll cook beautifully.
Step 4: Season Generously
Sprinkle garlic powder and black pepper evenly across the potatoes. Shake the packet of Lipton Onion Soup Mix to loosen it, then sprinkle the entire contents over the layers.
Step 5: Add Olive Oil
Slowly drizzle olive oil over the seasoned potatoes. This coats each slice, ensuring rich flavor and preventing dryness during cooking.
Step 6: Slow Cook to Perfection
Cover and cook on High for 4 hours. Avoid lifting the lid—it releases heat and moisture, slowing the cooking process. After 4 hours, the potatoes will be fork-tender, with slightly caramelized edges and a soft, buttery interior.
Step 7: Serve Hot
Use a spatula to gently lift the potatoes and serve them directly from the slow cooker. Garnish with chopped parsley or chives for a fresh touch. Serve hot for the best flavor and texture.

Storage Tips
Let the potatoes cool completely before storing.
- Refrigerate: Keep in an airtight container for up to 3 days.
- Reheat: Warm in the oven or air fryer to bring back the crispy edges. The microwave works too but will soften them.
- Freeze: Wrap portions in foil and freeze for up to 2 months. Reheat from frozen at 375°F until hot throughout.
Ingredient Substitutions
