Twice-Baked Sweet Potatoes with Bacon-Sesame Brittle

These twice-baked sweet potatoes offer a sophisticated twist on a classic comfort food favourite. By incorporating white miso and fresh ginger into the filling, the natural sweetness of the potatoes is balanced with a deep, savoury umami flavour. The dish is elevated further by a unique bacon and sesame brittle, providing a delightful crunch and a salty-sweet finish that makes these potatoes truly stand out as a centrepiece side dish.

Perfect for a weekend dinner party or a special family roast, this recipe can be partially prepared in advance to save time on the day. The combination of creamy mash and crisp topping fits beautifully into a modern British menu, especially when served alongside simple roasted meats or a crisp green salad for a lighter meal.

Ingredients for Twice-Baked Sweet Potatoes with Bacon-Sesame Brittle

  • 4 slices bacon, cut into 1/2"-wide pieces

  • 70g sugar

  • 1 tablespoon sesame seeds

  • 6 medium sweet potatoes (6-230g each)

  • 2 large eggs

  • 3 tablespoons unsalted butter, room temperature

  • 2 tablespoons white miso (fermented soybean paste)

  • 1 2/3" piece ginger, peeled, finely grated (about 2 teaspoons )

  • 2 1" pieces spring onion (dark-green parts only), thinly sliced lengthwise

  • Ingredient info: White miso, also called shiro miso, can be found at Asian markets and amazon.com.

Line a rimmed baking sheet with a silicone baking mat or parchment paper.

Cook bacon in a medium nonstick skillet over medium heat until most of the fat is rendered and bacon is starting to crisp. Transfer bacon to a sieve set over a small bowl; reserve drippings.

Return bacon, 1 tablespoon drippings, sugar, and sesame seeds to same skillet. Cook over medium heat, stirring frequently, until sugar turns the colour of milk chocolate, about 5 minutes. Transfer mixture to prepared baking sheet and use a spatula to spread out evenly; let cool. Break brittle into shards. DO AHEAD: Can be made 1 day ahead. Store airtight at room temperature.

Preheat oven to 204°C. Place sweet potatoes on a foil-lined baking sheet. Roast until tender, 45-55 minutes. Let sit until cool enough to handle.

Slice potatoes in half lengthwise. Working over a large bowl, scoop out flesh from 8 halves, leaving a 1/2"-thick layer inside skins. Place potato halves on same foil-lined baking sheet. Scoop flesh from remaining 4 halves; discard skins. Mash flesh with a whisk; add eggs, butter, miso, and ginger and stir until mixture is smooth. Spoon or pipe filling into reserved skins. DO AHEAD: Can be made 6 hours ahead. Cover and chill.

Bake potatoes until the tops are lightly puffed and golden brown, 30-35 minutes (potatoes will take longer if they've been chilled). Top potatoes with bacon-sesame brittle and spring onions.
