Ingredients
Instructions
- Adjust rack to top position and preheat oven to 425°F. Wash and dry all produce. Dice potatoes into ½-inch pieces. Peel and cut carrots diagonally into ½-inch-thick pieces. Thinly slice chives. Place potatoes in a large pot with enough salted water to cover by 2 inches. Boil until tender, about 15 minutes. Drain and return to pot.
- While potatoes cook, toss carrots on a baking sheet with a large drizzle of oil, salt and pepper. Roast until tender and lightly browned at the edges, about 15 minutes. Drizzle with honey and return to oven until caramelized and golden brown, 5-7 minutes more.
- While carrots roast, pat steak dry with paper towels; season all over with salt and pepper. Heat a large drizzle of oil in a large pan over medium-high heat. Add steak and cook until browned and cooked to desired doneness, 3-6 minutes per side. Turn off heat; transfer to a cutting board to rest for 5 minutes. Wipe out pan.
- Add demi-glace and ¼ cup water to same pan. Stir over low heat until slightly reduced, 1-2 minutes. Add garlic herb butter and any resting juices from steak. Stir until butter has melted. Turn off heat; season with salt and pepper.
- Mash potatoes with a potato masher or fork until smooth. Reserve 1 tablespoon chives; stir rest into mashed potatoes with sour cream and 2 tablespoons plain butter. Season with salt and pepper.
- Slice steak. Divide carrots, potatoes and steak between plates. Spoon sauce over potatoes and steak. Sprinkle carrots with chili flakes (to taste). Garnish the plate with reserved chives.
Recipe Tips
For the best sear, make sure the steak is patted very dry before seasoning.
Let the steak rest for 5 minutes after cooking to keep it juicy.
Adjust the chili flakes to your heat preference.
FAQ
Can I use a different cut of steak?
Yes, you can substitute with ribeye or strip steak; adjust cooking time as needed.
What can I use instead of demi-glace?
You can use beef broth reduced with a little cornstarch, but the flavor will be less rich.
How do I make the mashed potatoes ahead?
Mash the potatoes, then keep them warm in a covered pot over low heat, adding a splash of milk if needed.
