Equipment

  • 1 Baking Sheet
  • Parchment Paper (for lining)
  • Chef’s Knife (for trimming and halving)
  • Citrus Zester (for lemon zest)
  • Measuring Spoons (for seasoning and juice)

Ingredients
  

  • 1 pound Brussels sprouts ends trimmed and halved
  • Extra-virgin olive oil for drizzling
  • Sea salt to taste
  • Freshly ground black pepper to taste
  • 1 tablespoon fresh lemon juice
  • 2 teaspoons lemon zest
  • 1 tablespoon grated Parmesan cheese or ¼ cup shaved Parmesan
  • 1 tablespoon fresh thyme leaves
  • Fresh parsley leaves for garnish
  • Pinch of red pepper flakes optional

Instructions
 

  • Prepare the Oven and Baking Surface: Set your oven to preheat at 425°F (220°C). Line a baking sheet with parchment paper to prevent sticking and simplify cleanup.
  • Trim and Halve the Brussels Sprouts: Wash the Brussels sprouts, remove any damaged outer leaves, and trim the tough ends. Slice each sprout in half lengthwise to ensure they cook evenly.
  • Season and Arrange the Sprouts: Place the halved sprouts in a large bowl. Drizzle with olive oil and sprinkle generously with sea salt and freshly ground black pepper. Toss well to coat each piece. Spread the sprouts in a single layer on the prepared baking sheet, leaving space between them to promote crispiness.
  • Roast Until Golden and Tender: Roast in the preheated oven for about 20 to 30 minutes. Stir or shake the pan halfway through to encourage even browning. The Brussels sprouts are ready when they develop a deep golden color around the edges and feel tender when pierced with a fork.
  • Toss with Bright Lemon and Parmesan: Once roasted, transfer the sprouts to a serving bowl. Add the fresh lemon juice, lemon zest, grated Parmesan, and thyme leaves. Gently toss to combine and coat the sprouts with the fresh flavors.
  • Garnish and Serve: Sprinkle with fresh parsley leaves and, if you like a little heat, a pinch of red pepper flakes. Serve warm as a flavorful side dish.

Notes

  • For extra crispiness, make sure the sprouts are spread out without overcrowding on the baking sheet.
  • If you prefer a milder flavor, omit the red pepper flakes or reduce the amount.
  • Parmesan can be swapped for Pecorino Romano or a vegan cheese alternative for different tastes or dietary needs.
  • This recipe reheats well; simply warm leftovers in a skillet or oven to keep the crisp texture.
  • To save time, you can prep the Brussels sprouts a day ahead and keep them refrigerated until roasting.
