Black pepper jackets are a rustic British-style snack of whole baby potatoes roasted until their skins are deeply crisp and blistered, then tossed in a generous amount of cracked black pepper, flaky salt, and melted butter. The name comes from the “jacket”—the skin—which turns shatteringly crunchy while the inside stays fluffy. This recipe works because it uses a two-stage cooking method: boiling the potatoes first to soften the insides, then roasting at high heat to dry and crisp the skins, so you get the best of both textures in every bite.
Ingredients
- 1 ½ lb (680 g) baby potatoes or small new potatoes, about 1–2 inches (2.5–5 cm) across
- 2 tbsp (30 g) unsalted butter, melted
- 2 tbsp (30 ml) olive oil
- 2 tsp (6 g) coarsely cracked black pepper (or more to taste)
- 1 tsp flaky sea salt, plus more for the boiling water
- 1 tbsp (15 ml) apple cider vinegar (optional, for the boiling water)
- Fresh parsley or chives, chopped, for garnish (optional)
Instructions
- Preheat your oven to 425°F (220°C). Place a large baking sheet in the oven while it heats.
- Scrub the potatoes well—you want the skins clean since you’ll be eating them. Place them in a large pot and cover with cold water by about 1 inch (2.5 cm). Add 1 tablespoon of salt and the vinegar (if using) to the water. The vinegar helps the potatoes hold their shape during boiling.
- Bring to a boil over high heat, then reduce to a simmer. Cook for 12–15 minutes, until a knife slides into a potato with slight resistance—not fully tender, but close. Drain the potatoes and let them sit in the colander for 2–3 minutes to steam off excess moisture.
- While the potatoes are still warm, gently shake them in the colander to roughen the skins. This creates nooks and crannies that crisp up beautifully in the oven.
- In a large bowl, combine the melted butter and olive oil. Add the warm potatoes and toss to coat evenly. Season with the cracked black pepper and flaky salt, tossing again.
- Carefully remove the hot baking sheet from the oven. Spread the potatoes in a single layer, leaving space between them so they roast rather than steam.
- Roast for 25–30 minutes, flipping once halfway through, until the skins are deeply golden and crispy, and the potatoes are fully tender when pierced with a fork.
- Remove from the oven and transfer to a serving dish. Taste and add a little more salt or pepper if needed. Garnish with fresh herbs if using, and serve hot.
Tips
- Don’t skip the boiling step: Boiling the potatoes first ensures the insides are fluffy by the time the skins crisp. If you roast raw potatoes, the skins will burn before the centers cook through.
- Use freshly cracked pepper: Pre-ground black pepper lacks the aromatic punch that makes these jackets special. Crack whole peppercorns with a mortar and pestle or the bottom of a heavy pan—you want coarse pieces, not a fine powder.
- Make them spicier: Add a pinch of cayenne or smoked paprika along with the black pepper for extra heat and depth. If you prefer a milder version, reduce the pepper to 1 teaspoon.
- Choosing potatoes: Waxy varieties like Yukon Gold or red potatoes hold their shape well, but starchy russets will give a fluffier interior. Any small potato works—just adjust the boiling time if they’re larger than 2 inches (5 cm).
Serving Suggestions
Serve black pepper jackets as a side dish alongside roasted meats, grilled fish, or a simple green salad. They also make a great appetizer or party snack—set out a bowl with a side of sour cream, crème fraîche, or a tangy yogurt dip. For a heartier meal, top them with grated cheddar, crumbled bacon, or a dollop of sour cream and chives, turning them into loaded potato skins.
Variations
- Herb butter: Stir 1 tablespoon of chopped fresh rosemary, thyme, or dill into the melted butter before tossing with the potatoes.
- Garlic pepper jackets: Add 2 minced garlic cloves to the butter-oil mixture and let it sit for 10 minutes before tossing. The garlic infuses the fat, but be careful not to burn it in the oven.
- Lemon pepper jackets: Replace the black pepper with 1 tablespoon of lemon zest and 1 teaspoon of cracked black pepper. Toss the roasted potatoes with a squeeze of fresh lemon juice just before serving.
- Smoky version: Substitute 1 teaspoon of smoked paprika for half the black pepper and add a dash of liquid smoke to the butter mixture for a barbecue-style flavor.
Storage and Reheating
Leftover black pepper jackets will keep in an airtight container in the refrigerator for up to 4 days. To reheat, place them on a baking sheet in a 400°F (200°C) oven for 8–10 minutes, until hot and re-crisped. Avoid microwaving, as it will make the skins soggy. You can also freeze the roasted potatoes for up to 3 months—spread them on a baking sheet to freeze solid, then transfer to a freezer bag. Reheat from frozen in a 425°F (220°C) oven for 15–18 minutes, flipping once.
Frequently Asked Questions
Can I use regular-sized potatoes instead of baby potatoes?
Yes, but you’ll need to adjust the cooking time. Cut larger potatoes into 1–2 inch (2.5–5 cm) chunks before boiling, and reduce the boiling time to 10–12 minutes. Roast them for the same 25–30 minutes, or until crisp and tender.
Why do my potatoes stick to the baking sheet?
Make sure the baking sheet is thoroughly preheated before adding the potatoes, and ensure they are well-coated with the butter-oil mixture. If you’re still having trouble, line the sheet with parchment paper or a silicone mat—though you may lose a bit of crispiness on the bottom.
Can I make these ahead of time?
You can boil and coat the potatoes up to a day ahead, then refrigerate them in a covered bowl. When ready to serve, spread them on a baking sheet and roast as directed—add 5–10 minutes to the roasting time since they’ll be cold.
What if I don’t have flaky sea salt?
Use kosher salt or fine sea salt, but reduce the amount by about half, as fine salt packs more densely. Regular table salt can also work, but it may taste more metallic—use it sparingly.
Is it necessary to use vinegar in the boiling water?
No, it’s optional. The vinegar helps the potatoes hold their shape and prevents them from breaking apart, but you can skip it if you don’t have any on hand. The potatoes will still be delicious.
How do I get the skins extra crispy?
After boiling, make sure the potatoes are thoroughly dried before adding the fat. You can also pat them dry with a clean kitchen towel. The rougher the surface, the crisper the skin—so don’t be gentle when shaking them in the colander.
