Crushed Potatoes with Oyster Bar Butter

These crispy crushed potatoes with oyster bar butter offer a sophisticated twist on a classic side dish. By boiling the potatoes until tender and then lightly smashing them before frying, you create an abundance of craggy, golden edges that are perfect for catching the flavoured butter. This vegetarian recipe relies on a punchy combination of fresh tarragon, dill, and lemon to cut through the richness of the butter, resulting in a dish that is both comforting and vibrant.

Ideal for hosting a Sunday roast or a special weeknight dinner, this homemade favourite is packed with savoury flavour and fresh herbs. You can even prepare the herb butter and boil the potatoes a day in advance, making it a stress-free addition to your menu. Serve these alongside roasted vegetables or a simple green salad for a delicious, texture-rich meal that everyone will love.

How to make Crushed Potatoes with Oyster Bar Butter

Mix butter, garlic, lemon zest, lemon juice, hot sauce, Worcestershire sauce, and 1 tablespoon oil in a large bowl with a rubber spatula until smooth. Gently mix in parsley, chives, dill, and tarragon; season with salt and pepper.

Place potatoes and bay leaf in a large pot and pour in cold water to cover by 2"; season generously with salt. Bring to a boil, then reduce heat and simmer until potatoes are tender, 15–20 minutes. Drain, discard bay leaf, and let potatoes cool slightly. Using the flat side of a chef’s knife or the heel of your hand, smash potatoes lightly to flatten.

Heat 2 tablespoons oil in a large skillet over medium-high. Add half of potatoes and cook in a single layer, turning once, until brown and crisp, about 5 minutes. Transfer potatoes to bowl with herb butter. Wipe out skillet, repeat process with remaining 2 tablespoons oil and remaining potatoes. Toss potatoes in butter until they are all well coated (the warm potatoes should melt the butter).

Herb butter can be made 2 days ahead; cover and chill. Potatoes can be boiled and smashed 1 day ahead; let cool, then cover and chill. Pat dry before frying.
