Full Ingredients

Rosemary-Garlic Roast Potatoes

• 2 lb (900 g) Yukon Gold or russet potatoes, scrubbed and cut into 1-inch cubes
• 3 Tbsp extra-virgin olive oil

Step-by-Step Instructions

Step 1: Preheat the oven and pan

Place a large rimmed baking sheet (or two smaller ones) on the middle oven rack and preheat the oven to 425°F (220°C). Let the pan heat for at least 10 minutes once the oven reaches temperature. A hot pan helps the potatoes start sizzling on contact, which is key for a deeply crisp exterior.

While the oven heats, position a rack in the center and clear space so air can circulate freely around the pan. This prevents steaming and encourages browning.

Step 2: Prep and dry the potatoes

Scrub the potatoes well under running water to remove any dirt. You can peel them if you prefer a smoother texture, but leaving the skins on adds flavor and extra crisp edges.

Cut the potatoes into even 1-inch cubes. Try to keep them as uniform as possible so they cook at the same rate. Place the cut potatoes on a clean kitchen towel or paper towels and pat them very dry. Removing surface moisture is one of the most important steps for getting them truly crisp.

Step 3: Make the rosemary-garlic oil and toss

In a large mixing bowl, combine 3 Tbsp olive oil, 4 minced garlic cloves, 1 Tbsp chopped fresh rosemary, 1 tsp kosher salt, and 1/2 tsp black pepper. If using, add 1/4 tsp red pepper flakes for a bit of heat. Stir to distribute the garlic and rosemary evenly through the oil.

Add the dried potato cubes to the bowl. Toss thoroughly, turning the potatoes with a spatula or your hands until every surface is well coated in the seasoned oil. Take a moment to check that there are no big clumps of garlic in one spot; spread them out so the garlic can toast gently without burning.

Step 4: Arrange potatoes on the hot baking sheet

Carefully remove the preheated baking sheet from the oven, using oven mitts. You should hear a slight sizzle when the potatoes hit the pan.

Quickly spread the coated potatoes out in a single layer on the hot sheet. Do not overcrowd; if the pan looks crowded, divide the potatoes between two pans. Whenever possible, arrange the cubes so one flat cut side is in direct contact with the pan. Those surfaces will develop the best golden, crispy crust.

Step 5: Roast until golden, then flip

Return the pan to the oven and roast the potatoes for 20–25 minutes without stirring. This undisturbed time allows a crust to form and prevents them from tearing or sticking when you flip them.

After 20–25 minutes, remove the pan and gently flip the potatoes using a spatula, scraping up any browned bits. Rotate the pan when you return it to the oven to promote even browning.

Step 6: Finish roasting and season to taste

Continue roasting for another 15–20 minutes, or until the potatoes are deeply golden brown, crisp on the outside, and tender and fluffy inside when pierced with a fork. Total roasting time will be about 35–45 minutes, depending on your oven and the size of the cubes.

Transfer the hot potatoes to a serving bowl. Taste and add a pinch more salt and pepper if needed. If you like, drizzle with a teaspoon or two of olive oil, sprinkle with extra chopped rosemary or parsley, and finish with a shower of grated Parmesan. Serve immediately, with lemon wedges on the side for squeezing over just before eating.

Pro Tips

• Dry thoroughly: Water is the enemy of crispness. After cutting, really take the time to pat the potatoes dry before tossing with oil.
• Do not crowd the pan: If the potatoes are piled on top of each other, they will steam instead of roast. Use two baking sheets if needed.
• Use a hot pan: Preheating the baking sheet jump-starts browning and helps prevent sticking.
• Watch the garlic: If your oven runs hot, you can hold back half the garlic and toss it in with the potatoes during the last 10–15 minutes to prevent it from getting too dark.
• Serve right away: These are at their crispiest straight from the oven. If you must wait, keep them on the baking sheet in a warm oven (around 200°F / 95°C) for up to 20 minutes.

Variations

• Lemon-Parmesan Roast Potatoes: As soon as the potatoes come out of the oven, toss with 2–3 Tbsp grated Parmesan, the finely grated zest of 1/2 lemon, and a squeeze of lemon juice. Add extra black pepper.
• Smoky Paprika Potatoes: Add 1 tsp smoked paprika and 1/2 tsp garlic powder to the oil mixture before tossing with the potatoes. Garnish with parsley instead of rosemary.
• Sheet-Pan Dinner Version: During the last 15–20 minutes of roasting, add sliced chicken sausage or thick-cut vegetables (like carrots and red onion) to the pan, tossed in a bit of oil and salt, and roast until everything is cooked through and golden.

Storage & Make-Ahead

Let leftover potatoes cool completely, then store them in an airtight container in the refrigerator for up to 4 days. To reheat and re-crisp, spread them on a baking sheet and roast at 400°F (200°C) for 10–15 minutes, flipping once, until hot and crisp again. You can also reheat them in an air fryer at 375°F (190°C) for 5–8 minutes.

For a bit of prep ahead, you can cut the potatoes up to 4 hours in advance. Keep them submerged in cold water in the fridge, then drain and dry very thoroughly before tossing with oil and seasoning. Do not season early, as the salt can draw out moisture and soften the texture.
