Step‑by‑Step Instructions for Crispy Roast Potatoes with Rosemary and Garlic
Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). This high temperature is essential for achieving those deliciously crispy roast potatoes with rosemary and garlic. While the oven is heating, gather your ingredients and prepare to transform simple potatoes into a savory masterpiece.
Step 2: Prepare the Potatoes
Cut the yellow potatoes into large chunks, leaving smaller ones whole, halving medium potatoes, and quartering large ones for uniform cooking. Place them into a large pot. Add enough water to cover the potatoes, seasoning it generously with kosher salt to ensure enhanced flavor throughout.
Step 3: Boil the Potatoes
Bring the pot of salted water to a rolling boil, then stir in the baking soda. Boil the potatoes for about 10-15 minutes, or until they are soft enough to be pierced with a fork but not falling apart. This parboiling step is key for that fluffy texture inside your crispy roast potatoes.
Step 4: Shock the Potatoes
Once cooked, carefully drain the potatoes into a colander. Immediately transfer them into a bowl of ice water or rinse them under cold running water to halt the cooking process. This shocking step ensures the potatoes maintain their structure and aids in developing a crispy exterior.
Step 5: Season and Coat
In a large mixing bowl, combine the warmed duck fat (or alternative oil) with the garlic, freshly-cracked black pepper, and chopped rosemary. Gently toss the cooled potatoes in this aromatic mixture, ensuring each piece is well-coated for maximum flavor as they roast.
Step 6: Roast the Potatoes
Spread the seasoned potatoes onto a large baking sheet in a single layer, making sure they have room to breathe. Roast in the preheated oven for 45-60 minutes, turning them halfway through until they transform into golden-brown beauties. You’ll know they’re done when they are crispy on the outside and soft on the inside.
Step 7: Final Touch
Remove the crispy roast potatoes from the oven and let them sit for a few minutes. Before serving, sprinkle them with flaky sea salt for an extra touch of flavor and texture. Enjoy this delightful side that pairs beautifully with your favorite proteins, elevating any meal with ease.

Expert Tips for Crispy Roast Potatoes
-
Choose the Right Potatoes: Opt for yellow potatoes for the best texture; avoid using starchy potatoes, as they may turn mushy when roasted.

Turn for Even Cooking: Don’t forget to turn your potatoes halfway through roasting to ensure all sides become crispy and golden for the ultimate crispy roast potatoes with rosemary and garlic.

Finish with Flaky Sea Salt: Sprinkle flaky sea salt just before serving to elevate flavor and add delightful texture!
Storage Tips for Crispy Roast Potatoes with Rosemary and Garlic
Room Temperature: Allow potatoes to cool completely before storing. They can sit out for up to an hour, but should be refrigerated after that for best freshness.
Fridge: Store leftovers in an airtight container in the refrigerator for up to 3 days. This helps maintain flavor and texture while keeping them safe to eat.
Freezer: These crispy roast potatoes can be frozen for up to 2 months. Spread them out on a baking sheet until frozen, then transfer to a freezer bag to prevent stickiness.
Reheating: To restore crispiness, reheat in a preheated oven at 425°F (220°C) for about 15-20 minutes. This will bring back that delightful crunch of your crispy roast potatoes with rosemary and garlic.

Crispy Roast Potatoes with Rosemary and Garlic Recipe FAQs
What type of potatoes should I use for the best results?
Absolutely! I recommend using yellow potatoes for their creamy texture and flavor. They hold up well during roasting and create that perfect contrast between crispy exteriors and fluffy interiors. Avoid starchy varieties as they may turn mushy.
How should I store leftover crispy roast potatoes?
Once they have cooled completely, store your crispy roast potatoes in an airtight container in the refrigerator for up to 3 days. This will help maintain their flavor and texture, ensuring you can enjoy them later without losing quality!
Can I freeze the crispy roast potatoes?
Yes! To freeze, first, spread the crispy roast potatoes on a baking sheet in a single layer and place them in the freezer until they are frozen solid (about 2-3 hours). Then transfer them to a freezer-safe bag or container. They can be stored for up to 2 months!
What if my roast potatoes don’t turn out crispy?
Very common! Ensure that you don’t overcrowd the baking sheet, as this can lead to steaming instead of roasting, which prevents crispiness. Also, remember to parboil long enough to get them fork-tender without falling apart. Lastly, make sure your oven is hot enough at 425°F (220°C) for that golden, crispy finish.
Can I use other fats besides duck fat?
Definitely! While duck fat gives a rich flavor and excellent browning, you can substitute with olive oil, ghee, or beef tallow. Each will give a different taste and texture, so feel free to experiment based on your preference or dietary needs.
