Instructions
Prepare the Potatoes
Begin by scrubbing 2 pounds of Yukon Gold potatoes thoroughly under cold running water to remove any dirt or debris. Pat them completely dry with clean kitchen towels or paper towels. Using a sharp chef’s knife and stable cutting board, cut each potato into uniform 1-inch cubes, maintaining consistent size to ensure even cooking. Place all cubed potatoes in a large mixing bowl. Add 3 tablespoons of avocado oil, 1 teaspoon kosher salt, 1/2 teaspoon freshly ground black pepper, and 1/2 teaspoon garlic powder directly to the potatoes in the bowl. Use your hands or a large spoon to toss everything together until each potato piece is evenly coated with the oil and seasoning mixture. Tip: Cutting potatoes into uniform sizes prevents smaller pieces from burning while larger pieces remain undercooked.
Heat the Skillet
Place your 12-inch cast iron skillet on the stovetop over medium heat. Allow the empty skillet to preheat for exactly 5 minutes before adding any oil. You can test if the skillet is properly heated by sprinkling a few drops of water onto the surface – they should sizzle and evaporate immediately. Once preheated, carefully add the remaining 1 tablespoon of avocado oil to the hot skillet, swirling it around to coat the entire bottom surface evenly. The oil should shimmer but not smoke at this temperature. If you see smoke, reduce the heat slightly and wait 30 seconds before proceeding. This initial heating step ensures proper heat distribution and prevents the potatoes from sticking to the skillet surface during cooking.
Cook the Potatoes
Carefully add all the seasoned potato cubes to the preheated skillet in a single layer, making sure they’re evenly distributed without overcrowding. You should hear an immediate sizzle when the potatoes hit the hot surface. Do not stir or move the potatoes for the first 10 minutes of cooking – this allows a proper crust to form on the bottom surface. After 10 minutes, use a metal spatula to flip the potatoes, scraping any that may have stuck to the bottom. Continue cooking for another 15 minutes, flipping the potatoes every 5 minutes to ensure even browning on all sides. Tip: Resist the urge to stir frequently as this prevents proper crust formation and can make potatoes mushy.
Check for Doneness
After 25 total minutes of cooking time, test the potatoes for doneness by inserting a fork or sharp knife into several pieces. The potatoes should be tender all the way through with no resistance. The exterior should be deep golden brown with crispy edges. If the potatoes need more cooking, continue for additional 5-minute intervals, checking after each interval until desired texture is achieved. The total cooking time typically ranges from 25-35 minutes depending on your specific stove’s heat output and the exact size of your potato cubes. Look for an internal temperature of 205°F if using an instant-read thermometer for precise doneness measurement.
Finish and Serve
Once the potatoes reach your desired level of crispness and tenderness, immediately remove the skillet from the heat source. Transfer the cooked potatoes to a serving bowl or platter using a slotted spoon or spatula. Sprinkle 2 tablespoons of freshly chopped parsley over the hot potatoes and toss gently to distribute evenly. Serve immediately while still hot and crispy. Tip: Letting the potatoes rest in the hot skillet off heat for 2-3 minutes before serving helps any excess oil drain away and improves crispness.
Tips and Tricks
For optimal potato selection, choose Yukon Gold potatoes specifically for their balanced starch content and natural buttery flavor that complements the crispy exterior. If Yukon Golds are unavailable, red potatoes make an excellent substitute with their waxy texture that holds shape well. Avoid russet potatoes for this recipe as their high starch content can lead to excessive breaking and mushiness during the high-heat cooking process. When cutting your potatoes, aim for consistent 1-inch cubes – pieces that are too small will burn quickly while larger pieces may remain undercooked in the center. If you notice significant size variations after cutting, consider cooking smaller and larger pieces separately for perfect results.
Proper skillet maintenance significantly impacts your cooking results. Always ensure your cast iron skillet is properly seasoned before use – a well-seasoned surface should appear dark and slightly glossy, not dull or rusty. If your potatoes consistently stick to the skillet, your seasoning may need refreshing. To test seasoning, heat a small amount of oil in the empty skillet – if it smokes excessively or develops dark spots quickly, consider re-seasoning your pan. When cleaning your cast iron after cooking potatoes, avoid using soap if possible. Instead, use coarse salt and a stiff brush to scrub away residue, then wipe with a paper towel and apply a thin layer of oil before storage.
Temperature control remains crucial throughout the cooking process. Medium heat provides the ideal balance between developing a crispy crust and cooking the interior thoroughly. If your potatoes brown too quickly on the outside while remaining raw inside, reduce the heat slightly and extend cooking time. Conversely, if browning occurs too slowly, increase heat incrementally. For consistent results, use an infrared thermometer to check your skillet’s surface temperature – aim for 350-375°F before adding potatoes. When flipping potatoes, work quickly to maintain skillet temperature and use a metal spatula with a thin edge to properly lift and turn each piece without tearing the crispy surface.
Recipe Variations
For a spicy twist, add 1 teaspoon smoked paprika and 1/2 teaspoon cayenne pepper to the initial seasoning mixture. The smoked paprika contributes deep, smoky notes while the cayenne provides gradual heat that builds with each bite. You could also incorporate 1 tablespoon of chili powder for a southwestern flavor profile that pairs well with grilled meats or breakfast dishes. Consider finishing with a sprinkle of crushed red pepper flakes for additional heat and visual appeal.
Herb-infused variations offer aromatic complexity. Replace the basic parsley garnish with 2 tablespoons of fresh rosemary, thyme, or a combination of both. For rosemary, chop it finely to distribute the potent flavor evenly. Thyme works well when using whole leaves stripped from the stems. You could also create an herb butter finish by melting 2 tablespoons of unsalted butter with your chosen herbs and drizzling over the finished potatoes just before serving.
Cheese-topped potatoes provide rich, indulgent options. During the last 5 minutes of cooking, sprinkle 1/2 cup of grated Parmesan, sharp cheddar, or Gruyère cheese over the potatoes. Cover the skillet briefly to melt the cheese evenly. For extra crispness, transfer the skillet under a preheated broiler for 1-2 minutes until the cheese bubbles and browns slightly. Always grate your own cheese rather than using pre-shredded varieties, which contain anti-caking agents that can prevent proper melting.
Frequently Asked Questions
Can I use other types of potatoes for this recipe?
Yes, you can substitute Yukon Gold potatoes with other varieties, though results will vary. Red potatoes work well with their waxy texture that maintains shape during cooking. Fingerling potatoes sliced lengthwise offer excellent surface area for crisping. Avoid russet potatoes as their high starch content makes them prone to breaking apart and becoming mushy. Sweet potatoes can be used but require adjusted cooking times due to different moisture content and sugar levels that caramelize faster. Always cut alternative potato varieties into uniform sizes and adjust cooking time based on texture observations during the process.
Why do my potatoes stick to the cast iron skillet?
Potatoes typically stick due to insufficient preheating, inadequate oil, or poor skillet seasoning. Ensure your skillet preheats fully for 5 minutes over medium heat before adding oil. The oil should shimmer but not smoke when potatoes are added. If sticking persists, your cast iron may need re-seasoning. Proper seasoning creates a natural non-stick surface through polymerized oil layers. Also avoid moving potatoes too soon after adding to the skillet – wait at least 10 minutes for a crust to form before flipping. Using a metal spatula with a thin edge helps release potatoes cleanly from the surface.
Can I prepare these potatoes ahead of time?
You can par-cook potatoes up to 24 hours in advance. After the initial 15 minutes of cooking, remove potatoes from heat and let cool completely. Store in an airtight container in the refrigerator. When ready to serve, return to a preheated cast iron skillet and cook for remaining 10-15 minutes until hot and crispy. This method actually improves texture as the cooling period allows starches to retrograde, resulting in crispier final product. Avoid fully cooking and reheating as this typically produces soggy potatoes. For best results, complete the final cooking stage just before serving.
What’s the best oil for cooking cast iron potatoes?
Avocado oil works ideally due to its high smoke point of 520°F, neutral flavor, and health benefits. Grapeseed oil serves as an excellent alternative with similar high smoke point. Avoid olive oil for this recipe as its lower smoke point can create bitter flavors and smoke during extended cooking. Vegetable and canola oils work adequately but may impart slight flavors. For dairy-free options, refined coconut oil provides good results. Always choose oils with smoke points above 400°F for cast iron cooking to prevent burning and maintain oil integrity throughout the cooking process.
How do I know when the potatoes are fully cooked?
Check doneness through multiple methods for accuracy. Visually, potatoes should display uniform golden brown coloring on all surfaces. Texturally, they should feel crispy on the exterior when tapped with a spatula. Internally, insert a fork or knife into several pieces – there should be no resistance and the interior should appear fluffy and cooked through. For precise measurement, use an instant-read thermometer inserted into the largest potato piece – it should register 205°F when fully cooked. If potatoes brown before reaching proper internal temperature, reduce heat and continue cooking until tender throughout.
Summary
Cast iron potatoes achieve perfect crispness through proper technique and quality ingredients. The method relies on even heating, uniform cutting, and patient cooking for consistent results. This versatile side dish complements various meals while maintaining simplicity in preparation and execution.
