Crispy Roasted Purple Majesty Potatoes with Herb Oil & Flaky Salt

Purple Majesty potatoes are one of those ingredients that stop people in their tracks. Cut one open and the deep violet flesh — almost jewel-like — is striking enough that you want to do it justice. The best way to cook them is also the simplest: roast them hard and hot so the skins blister and crisp while the insides go fluffy and tender, then finish with a quick herb oil and a shower of flaky salt. The color deepens as they roast, going from purple to something almost indigo. They taste earthy, nutty, and richly satisfying — everything a potato should be.

Ingredients

• 1.5 lb Purple Majesty potatoes, scrubbed and halved lengthwise
• 3 tbsp extra-virgin olive oil, divided
• 1 tsp kosher salt
• 1/2 tsp freshly ground black pepper
• 2 cloves garlic, finely minced or grated
• 2 tbsp fresh herbs, finely chopped (rosemary, thyme, or flat-leaf parsley — or a mix)
• Flaky sea salt, to finish
• Optional: a squeeze of lemon or a splash of red wine vinegar to finish

Instructions

1. Preheat and prep the pan: Place a heavy baking sheet or cast iron pan in the oven and preheat to 425°F. Getting the pan screaming hot before the potatoes go in is what creates that immediate crust — don't skip this step.
2. Season the potatoes: In a large bowl, toss the halved potatoes with 2 tbsp of the olive oil, kosher salt, and black pepper. Make sure every cut face is coated.
3. Roast cut-side down: Carefully remove the hot pan from the oven and arrange the potatoes cut-side down in a single layer — you should hear a satisfying sizzle as they hit the pan. Roast for 20–25 minutes without moving them, until the cut faces are deeply golden and the skins are starting to wrinkle and crisp.
4. Flip and finish: Flip the potatoes and roast for another 8–10 minutes until the skins are fully crisped and the flesh is completely tender when pierced with a knife. The color should be rich and deep — a dark, saturated purple.
5. Make the herb oil: While the potatoes finish roasting, combine the remaining 1 tbsp olive oil with the garlic and chopped herbs in a small bowl. Let it sit for a few minutes to infuse.
6. Dress and serve: Transfer the potatoes to a serving platter, drizzle the herb oil over the top, and finish with a generous pinch of flaky sea salt. Add a squeeze of lemon or a small splash of vinegar if you want brightness. Serve immediately.

Tips

• The hot pan method is non-negotiable for crispy cut faces. A cold pan steams the potatoes instead of searing them, and you lose the crust entirely.
• Don't crowd the pan — if the potatoes are packed too tightly, they'll steam rather than roast. Use two pans if needed.
• Purple Majesty potatoes hold their color better than most purple varieties. A small splash of acid (lemon or vinegar) at the end helps preserve and brighten that vivid violet hue on the plate.
• Leaving the skins on is essential — they crisp beautifully and add earthy depth. Just scrub them well.

Variations

• Add anchovy depth: Mash 1–2 anchovy fillets into the herb oil before drizzling — they melt in and add an umami backbone without any fishiness.
• Go dairy: A spoonful of crème fraîche or a drizzle of good sour cream alongside the herb oil is a stunning contrast against the purple flesh.
• Smash them: After the first 20-minute roast, use the bottom of a glass to gently smash each potato flat before flipping. You get maximum crispy surface area.
• Spice it up: Add 1/2 tsp smoked paprika and a pinch of cayenne to the initial seasoning for a more assertive flavor profile.

Pairs Well With

• Grass-fed steaks — the earthy, nutty potato is a perfect counterpoint to rich, beefy fat
• Roasted chicken with pan drippings spooned over the top
• A simple green salad with sharp vinaigrette to balance the richness
• Fried or poached eggs for a stunning, colorful weeknight dinner
