Ingredients
1. 2 large chicken breasts or 4 small ones
2. 2 tablespoons olive oil
3. 1 teaspoon salt
4. 1 teaspoon freshly cracked black pepper (plus extra for sauce)
5. 1 teaspoon paprika
6. 1 cup heavy cream
7. ½ cup chicken broth
8. 2 tablespoons butter
9. 1 tablespoon flour (for thickening)
10. 1 pound Brussels sprouts, trimmed and halved
11. 2 tablespoons olive oil (for Brussels)
12. 1 ½ pounds potatoes, peeled and chopped
13. ½ cup milk (warm)
14. 2 tablespoons butter (for mash)

Instructions
1. Preheat oven to 425°F (220°C).
2. Toss Brussels sprouts with olive oil, salt, and pepper, then spread on a baking sheet. Roast for 20–25 minutes, flipping halfway through.
3. Meanwhile, place potatoes in salted water and boil until tender (about 15 minutes). Drain, then mash with butter and warm milk until smooth. Set aside.
4. Season chicken with salt, pepper, and paprika. Heat olive oil in a skillet over medium-high heat and sear chicken for 5–6 minutes per side, until golden and cooked through. Remove and keep warm.
5. In the same skillet, melt butter, stir in flour, and cook for 1 minute. Slowly whisk in chicken broth, then cream, and add a generous crack of black pepper. Simmer until thickened.
6. Return chicken to the sauce, spooning it over to coat well.
7. Serve chicken over mashed potatoes with roasted Brussels on the side, drizzling extra sauce over the top.

The Brussels sprouts are nutty and caramelized, while the mashed potatoes are smooth and buttery—perfect for soaking up every drop of that sauce. The pepper gives it a kick that keeps you coming back for bite after bite.
