Chunky potatoes roasted at high heat with garlic, rosemary, and a crunchy exterior — the perfect crisply golden side.

Ingredients

Scale

4 lbs russet or Yukon Gold potatoes, cut into large chunks

2 tbsp kosher salt

½ tsp baking soda

5 tbsp olive oil (or fat of your choice)

3 cloves garlic, minced

Small handful fresh rosemary, chopped

Black pepper, to taste

Small handful parsley, minced

Instructions

1. Preheat oven to 450°F (or 400°F convection).

2. Bring 2 quarts water to a boil with 2 tbsp kosher salt and ½ tsp baking soda.

3. Add potato chunks and simmer 10 minutes until just tender.

4. Meanwhile, heat olive oil (or fat) in a small saucepan with garlic and rosemary until fragrant, then strain.

5. Drain potatoes and let steam briefly, then place in a bowl with infused oil.

6. Toss vigorously to roughen surfaces.

7. Spread potatoes on a baking sheet in a single layer.

8. Roast 20 minutes without moving.

9. Use a thin spatula to loosen, then turn and continue roasting 30–40 minutes, shaking a few times.

10. Once crisp and golden, toss with reserved garlic, rosemary, and parsley. Serve immediately.

Notes

Adjust roast time depending on your oven — start checking around 30 minutes.

Use preheated baking sheet for extra crisp.

To reheat, roast in oven at 425°F for 8–10 minutes.
