This elegant side dish of roasted carrots with fennel-brown butter brings a sophisticated depth of flavour to any meal. By roasting the carrots at a high temperature, their natural sweetness intensifies, providing a beautiful contrast to the earthy, aromatic fennel seeds. The addition of brown butter—or beurre noisette—adds a rich, toasted note that elevates this humble root vegetable into something truly special for a dinner party or a family roast.
As a low-sugar recipe, this dish relies on quality ingredients and simple techniques rather than heavy glazes. Using the carrot tops as a garnish adds a fresh, peppery finish and ensures nothing goes to waste in your kitchen. These carrots are best served warm alongside roast chicken, pan-fried fish, or as part of a seasonal vegetarian spread.

Ingredients for Roasted Carrots with Fennel-Brown Butter
675g medium carrots, with green tops, if available
1 tablespoon plus 2 teaspoons olive oil
1/2 teaspoons sugar
1/2 teaspoons kosher salt
1/4 teaspoons freshly ground black pepper
1 1/2 teaspoons fennel seeds
1 1/2 tablespoons unsalted butter
1 1/2 teaspoons fresh lemon juice
How to make Roasted Carrots with Fennel-Brown Butter
Preheat oven to 218°C. Trim carrot tops and coarsely chop. Measure out 2 tablespoons carrot tops and set aside; reserve any remaining carrot tops for another use. Peel carrots, slice in half lengthwise, then cut into 2" pieces.
Toss carrots with oil, sugar, salt, and pepper on a rimmed baking sheet. Arrange in a single layer and roast carrots, stirring halfway through, until tender and lightly caramelized, 25–35 minutes.
Meanwhile, lightly crush fennel seeds using a mortar and pestle or the bottom of a heavy pan. Melt butter in a medium skillet over medium heat, then stir in crushed seeds. Cook, stirring occasionally, until foam subsides and butter becomes fragrant, nutty, and golden brown, 3–5 minutes. Transfer butter mixture to a medium bowl.
Once carrots are roasted, add them to butter mixture and toss to coat. Add lemon juice and toss to coat. Serve carrots topped with reserved carrot tops.
