- Prep time: 15 minutes
- Cook time: 25–30 minutes
- Serves: 4
Ingredients
- Potatoes: 2 lbs (about 3–4 large) Russet or Yukon Gold potatoes.
- Note: Russets give a fluffier inside and crispier outside; Yukon Golds hold their shape better and have a buttery flavor.
- Onion: 1 large yellow or white onion, thinly sliced or diced.
- Fat: 2 Tbsp olive oil and 2 Tbsp salted butter (or 3–4 Tbsp bacon grease for maximum flavor).
- Seasoning: 1 tsp salt, ½ tsp black pepper, and ½ tsp paprika (optional, for color and smokiness).
- Optional Garnish: Fresh chopped parsley, chives, or green onions.
Instructions
1. Prepare the Potatoes
Wash and peel the potatoes (peeling is optional for Yukon Golds). Cut them into ½-inch cubes or ¼-inch thick slices.
- Pro Tip: For extra crispiness, soak the cut potatoes in cold water for 15–30 minutes to remove excess starch. If you do this, pat them completely dry with a paper towel before frying to prevent steaming and oil splatter.
2. Heat the Pan
Place a large heavy-duty skillet (cast iron is best) over medium heat. Add the oil and butter (or bacon grease). Wait until the butter is melted and the oil is shimmering.
3. The “First Sear”
Add the potatoes to the skillet in a single layer. Do not overcrowd the pan; if necessary, cook in batches. Sprinkle with half of the salt and pepper.
- The Golden Rule: Let the potatoes cook undisturbed for 5–7 minutes. Do not stir them! This allows the bottom to form a crispy, golden-brown crust.
4. Flip and Add Onions
Once the bottoms are browned, use a wide spatula to flip the potatoes. Add the sliced onions and the remaining seasoning (and paprika, if using).
5. Continue Cooking
Reduce the heat slightly to medium-low. Continue to fry for another 15–20 minutes, flipping only every 5 minutes.
- Texture Check: You want the onions to become soft, sweet, and caramelized, while the potatoes become fork-tender and “charred” on the edges.
6. Final Touch
Taste and add more salt or pepper if needed. Remove from heat and garnish with fresh herbs. Serve hot.
Success Tips for the Best Results
- Don’t Over-Stir: Moving the potatoes too much breaks them down and prevents the crust from forming.
- The Right Pan: Cast iron retains heat better than non-stick, which is essential for that “diner-style” crust.
- Add Onions Later: If you add onions at the very beginning, they will likely burn before the potatoes are fully cooked. Adding them halfway through is the sweet spot.
- Avoid the Lid: While covering the pan helps potatoes cook faster (by steaming), it can make them soft. For maximum crunch, keep the lid off.
