Preheat oven to 425°F. Line a large baking sheet with parchment paper.
Clean your 450 g Brussels sprouts and trim the ends and cut them in halves. Make sure to remove the outer layer if you see impurities. Make sure they are dry.
Clean your 680 g small mixed potatoes and quarter them. Make sure to remove parts of the layer if you see big impurities. Make sure they are dry.
The Roast
In a large mixing bowl, toss the halved 450 g Brussels sprouts and 680 g small mixed potatoes with 45 ml olive oil, 15 ml balsamic vinegar, 1 tsp. salt (to taste) and ½ tsp. freshly ground black pepper (to taste).
Arrange cut-side down on the large baking sheet with parchment paper for maximum char. Roast for 22–25 minutes until crispy.Denis’s Tip: Always place your sprouts and potatoes with the flat, cut side touching the parchment paper. This creates a hard char that stands up to the lemon butter.
The Sear
Slice the 680 g chicken breasts into 1-inch strips, cutting against the grain for surgical tenderness.
Pat the 680 g chicken breasts strips bone-dry with paper towels. Season evenly with 1 tsp smoked paprika, 1 tsp. salt (to taste), and ½ tsp. freshly ground black pepper (to taste).
Heat a cast-iron skillet over medium-high. Sear chicken in oil in batches for 3 minutes per side. Do not force the flip, wait for the Maillard release. Set aside on a paper towel.
The Sauce
Lower heat. Sauté 6 garlic cloves for 30 seconds. Pour in 90 ml dry white wine (Sauvignon Blanc or Pinot Grigio) to deglaze, scraping the pan. Reduce liquid by half.
Turn off the heat. Add in 85 g unsalted butter in a few batches. Stir in 1 lemon juice and 1 lemon zest. Season with ½ tsp. Italian seasoning and ¼ tsp. crushed red pepper.Denis’s Tip: This prevents the dried herbs from burning in the high-heat skillet and allows their oils to bloom perfectly in the warm butter.
The Serving
Plate crispy vegetables first. Place chicken next to them and pour the warm emulsion strictly over the meat only. Garnish with fresh parsley.
