Slice 2 pounds of potatoes 1/8-inch thick using a mandoline. Heat a cast iron skillet with oil, then arrange potato slices in overlapping spiral pattern from outside edge to center. Brush with garlic butter, season, and bake at 425°F for 45-60 minutes until golden and crispy.

Both use thinly sliced potatoes arranged in overlapping patterns, but spiral potatoes form concentric circles in a cast iron skillet, while domino potatoes are typically arranged in straight, overlapping rows in a baking dish. The cooking method and crispiness are similar.

For perfectly crispy roasted garlic potatoes, bake at 425°F (220°C) for 45-60 minutes. This high heat creates the ideal golden crust while keeping the interior fluffy. Lower temperatures like 375°F will take 55-65 minutes, while 450°F reduces cooking time to 35-45 minutes but requires closer monitoring to prevent burning.

Slice potatoes 1/8 to 1/4 inch thick using a mandoline slicer for best results. This thickness ensures even cooking, with crispy edges and tender centers. Thinner slices may become too crispy, while thicker slices won’t cook evenly and may remain undercooked in the center.

Yukon Gold potatoes or Idaho potatoes (russet potatoes) are ideal for this recipe because they have a perfect balance of starch and moisture, creating crispy exteriors with creamy interiors. Russet potatoes work well too for extra crispiness, while red potatoes hold their shape but won’t get as crispy.

Start from the outer edge of your cast iron skillet and work inward in concentric circles. Place potato slices vertically at a slight angle, overlapping each slice by about half. Use larger slices around the perimeter and smaller pieces toward the center for an even spiral pattern.

No, do not soak thinly sliced potatoes for this recipe. Soaking removes surface starch that helps create crispy edges. Instead, pat slices dry with paper towels and immediately toss with oil and seasonings to prevent browning and achieve maximum crispiness.

Common causes include: overcrowding the skillet, insufficient oil, low oven temperature, or excess moisture. Ensure potato slices are coated well with oil and butter for the best possible crispiness. Leave space between slices and avoid covering the skillet during cooking.

Preheat your well-seasoned cast iron skillet with the butter before adding potatoes. Use enough fat (oil or butter) to coat the bottom, and avoid moving the potatoes until they’ve developed a golden crust, which naturally releases from the pan.

Do not flip spiral-arranged potatoes as this will destroy the pattern. Instead, brush the tops with additional oil or melted butter halfway through cooking to ensure even browning and crispiness on exposed surfaces.

Use 4-6 cloves of fresh garlic for 2 pounds of potatoes, either minced or thinly sliced. (I used two cloves for three potatoes but easily could have added more – know your audience…LOL) For mellower flavor, use whole smashed cloves that can be removed after cooking. Avoid garlic powder as it burns easily at high temperatures.

Yes, but a mandoline ensures uniform thickness for even cooking. If using a knife, slice as evenly as possible and aim for consistent 1/4-inch thickness. A food processor with slicing disc is another alternative, though slices may be less uniform. But this does make the job really fast and easy.

Use high-heat oils like avocado oil, canola oil, or vegetable oil. These oils have high smoke points and won’t burn at roasting temperatures. Olive oil works but use light olive oil rather than extra virgin, which has a lower smoke point.  Note:  I’ve used butter in my recipe but you could substitute oil or use a combination of half and half.  I went for all the flavor in this recipe.

Yes! Add grated Parmesan, Gruyère, or sharp cheddar during the last 15 minutes of cooking to prevent burning. Sprinkle between layers for melted pockets throughout, or just on top for a golden cheese crust.

Thinly sliced spiral potatoes in cast iron take about 1 hour at 425 degrees F until golden and crispy. Thicker cuts or lower temperatures will extend cooking time. Every oven is different so you want to look for golden-brown edges and tender centers when testing for doneness. To test, just insert the tip of a paring knife into the middle potatoes. If it slides in easily, the potatoes are done. Then, just check for browning and crispiness.

Slice potatoes and arrange in the skillet up to 2 hours before cooking, but brush immediately with oil to prevent browning. For best results, assemble and cook immediately. Cooked potatoes can be reheated at 400°F for 10-15 minutes to restore crispiness.

Reheat in a 400°F oven for 10-15 minutes, or use an air fryer at 375°F for 5-8 minutes. Avoid microwaving, which makes potatoes soggy. A cast iron skillet on the stovetop also works well for restoring crispiness.

Soggy potatoes result from overcrowding, insufficient oil, too low temperature, or excess moisture. Ensure slices don’t overlap too much, use adequate fat, roast at high heat (425°F+), and pat potatoes dry before seasoning.

Look for crispy golden bottoms, tender middle pieces, and a touch of crunch on top. Test doneness by inserting a fork or tip of paring knife into the center – it should slide in easily. The edges should be deeply golden brown and crispy.

Fresh potatoes work best for this recipe. Frozen potatoes contain excess moisture that prevents proper crisping and may break apart when arranged in spiral patterns. If using frozen, thaw completely and pat very dry before proceeding.

Use extra oil or butter to prevent sticking, or line the bottom with parchment paper (though this may reduce bottom crispiness). Well-seasoned cast iron gives the best results, so consider re-seasoning your pan if food consistently sticks.

These potatoes complement roasted meats like beef, pork dishes like my baked breaded pork chops with blackberry sauce, or chicken. They’re excellent with steaks, roast leg of lamb, grilled fish, or as part of a vegetarian meal with roasted vegetables and a fresh salad.

A 10 or 12-inch cast iron skillet works best. The 10-inch uses about 1.5 pounds of potatoes (serves 4-6), while a 12-inch accommodates 2-2.5 pounds (serves 6-8). Smaller skillets don’t allow proper spiral arrangement.

Yes! Sweet potatoes work beautifully in this recipe. Use the same slicing technique but reduce cooking time to 35-45 minutes at 425°F, as sweet potatoes cook faster than regular potatoes. Add cinnamon or maple syrup for extra flavor.

Absolutely! Spiral cast iron potatoes make an impressive, Instagram-worthy side dish that rivals traditional mashed potatoes. They can be partially prepped ahead and take up only one skillet, freeing oven space for other dishes. The presentation always wows guests.

Yes, they hold well at room temperature and look stunning on a buffet table served directly in the cast iron skillet. The crispy texture doesn’t get soggy like other potato dishes, and guests can easily serve themselves portions of the spiral.
