Instructions

  1. Preheat your oven to 425°F. Wash and dry all produce. Cut potatoes into 1-inch chunks. Peel and cut carrots into ½-inch thick rounds. Peel and cut red onion into wedges.
  2. On a baking sheet, toss carrots and red onion with 2 teaspoons cooking oil, salt and pepper. Roast for 20-25 minutes, until tender and lightly browned.
  3. Meanwhile, place potatoes in a pot and cover with salted water. Bring to a boil and cook until fork-tender, about 15 minutes. Drain and return to pot.
  4. While potatoes cook, pat bavette steak dry with paper towels. Season generously with salt and pepper on both sides.
  5. Heat 2 teaspoons cooking oil in a large skillet over medium-high heat. Add steak and cook for 4-5 minutes per side for medium-rare or to your desired doneness. Remove steak from skillet and let rest on a cutting board.
  6. Reduce heat to medium. Add butter, rosemary and chicken stock concentrate to the skillet. Stir, scraping up any browned bits, until butter is melted and sauce is slightly thickened, about 1 minute. Remove from heat.
  7. Mash the drained potatoes with sour cream, 1 tablespoon butter (or to taste), salt and pepper until smooth and creamy.
  8. Slice the rested steak against the grain. Serve steak with mashed potatoes and roasted vegetables. Drizzle pan sauce over steak.

Recipe Tips

Let the steak rest for at least 5 minutes before slicing to keep it juicy.

For extra creamy mashed potatoes, warm the sour cream before adding.

Adjust roasting time for carrots and onions if you prefer them more or less caramelized.

Use a meat thermometer: 130°F for medium-rare, 140°F for medium. Let rest before slicing.

Can I make this dairy-free?
