Step‑by‑Step Instructions for Crispy Roast Potatoes with Rosemary and Garlic
Step 1: Prep the Potatoes
Begin by peeling the yellow potatoes and cutting them into large chunks; leave smaller potatoes whole, halve medium ones, and quarter the largest. Rinse the cut potatoes under cold water to remove excess starch, which will help achieve a crispier result. Set them aside while you prepare for the next step.
Step 2: Parboil
Bring a large pot of salted water to a rolling boil, then gently add the prepared potatoes. Parboil them for about 10 minutes, or until they are just starting to soften but still firm in the center. Drain the potatoes in a colander and immediately transfer them to a bowl of cold water to halt the cooking process.
Step 3: Roasting Preparation
Preheat your oven to 425°F (220°C) and grab a large roasting pan. Pour duck fat into the pan, ensuring it coats the bottom evenly. Place the pan in the oven while it preheats, allowing the fat to melt and become hot—this step is crucial for achieving the perfect crispy roast potatoes.
Step 4: Mix Seasoning
In a mixing bowl, combine the parboiled potatoes with baking soda, kosher salt, cracked black pepper, finely chopped rosemary, and whole garlic head. Toss everything together gently but thoroughly to ensure each potato is evenly coated and infused with the aromatic flavors, setting the stage for your Crispy Roast Potatoes with Rosemary and Garlic.
Step 5: Roast the Potatoes
Carefully remove the hot roasting pan from the oven and quickly add the seasoned potatoes, spreading them in a single layer. Roast in the oven for about 1 hour, turning them every 20 minutes to expose all sides to the heat. The potatoes are done once they are golden brown and irresistibly crispy on the outside while fluffy on the inside.
Step 6: Final Touch
In the last 5 minutes of roasting, drizzle olive oil over the potatoes and sprinkle with flaky sea salt to enhance their flavor. This final step elevates the crispy texture and ensures each bite is deliciously seasoned, ready to impress your guests or family with these Crispy Roast Potatoes with Rosemary and Garlic.

Expert Tips for Crispy Roast Potatoes
-
Cut Size Matters: Be sure to cut the potato chunks large enough to prevent them from becoming mushy during roasting, leading to perfectly crispy roast potatoes with rosemary and garlic.
-
Parboil Wisely: Avoid overcooking the potatoes during the parboil step; you want them tender but still firm enough to hold their shape, which is crucial for crispiness.
-
Hot Fat Is Key: Always place the potatoes in hot duck fat for the best crisp. This ensures they start the roasting process sizzling and creates that golden-brown exterior.
-
Season Generously: Don’t be shy with your seasonings! The more flavor you impart during mixing, the more delicious your crispy roast potatoes will be. Adjust salt and pepper to taste.
-
Flip for Evenness: Remember to turn the potatoes every 20 minutes while roasting. This technique ensures that all sides achieve a uniform golden brown and crunchy exterior.
Make Ahead Options
These Crispy Roast Potatoes with Rosemary and Garlic are a fantastic option for meal prep, as they can be parboiled up to 24 hours in advance. To prepare ahead, simply peel and cut the potatoes, then parboil them for about 10 minutes until just softened. Once drained, immerse them in cold water to halt the cooking process, then cover and refrigerate. This technique helps maintain their texture and ensures they remain fluffy inside while crispy on the outside when roasted. On the day you plan to serve, simply toss the potatoes with the seasoning mix and roast as directed. You’ll enjoy the same delectable flavor and crispy results with far less hassle!

Crispy Roast Potatoes with Rosemary and Garlic Recipe FAQs
How do I choose the right potatoes for crispy roast potatoes?
Absolutely! When selecting potatoes, I recommend using yellow potatoes for their perfect balance of fluffiness and structure. Look for potatoes that are firm, smooth, and free of dark spots. They should feel heavy for their size—avert those with wrinkling or sprouting, as they won’t roast well!
How should I store leftover crispy roast potatoes?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To enjoy them at their best, I suggest reheating them in the oven. Just preheat to 400°F (200°C) and bake for 10-15 minutes until they’re crispy again!
Can I freeze crispy roast potatoes?
Absolutely! To freeze, first arrange the crispy roast potatoes in a single layer on a baking sheet and place them in the freezer until firm, which usually takes about an hour. Then, transfer them to a freezer-safe bag or container, where they can stay good for up to 2 months. When you’re ready to enjoy them again, reheat directly from frozen in a preheated oven at 400°F (200°C) for approximately 15-20 minutes.
What if my potatoes are not crispy after baking?
No worries! If your crispy roast potatoes with rosemary and garlic didn’t achieve that golden crunch, it might be due to overcrowding in the pan or insufficient oven temperature. Make sure to spread the potatoes in a single layer, providing enough space for air to circulate. Another tip is to return them to the oven for an additional 10 minutes at a higher temperature if needed.
Are crispy roast potatoes suitable for special diets?
Yes, indeed! These crispy roast potatoes are Whole30 compliant and gluten-free, making them an excellent addition for those following a variety of dietary restrictions.
