Instructions

  1. Preheat oven to 425°F. Cut potatoes into 1-inch pieces. Toss with olive oil, salt and pepper. Spread on a baking sheet and roast for 20-25 minutes until golden and tender.
  2. While potatoes roast, pat beef tenderloin dry with paper towels. Season generously with bold & savory steak spice on all sides.
  3. Heat cooking oil in a large skillet over medium-high heat. Sear beef for 3-4 minutes per side for medium-rare or until desired doneness. Transfer to a plate and tent with foil.
  4. Reduce heat to medium. Add diced onion to the skillet and cook until softened, about 2 minutes. Stir in beef stock concentrate and 1/4 cup water, scraping up browned bits. Simmer for 1 minute, then remove from heat. Stir in sour cream until smooth. Season with salt and pepper.
  5. Bring a pot of salted water to a boil. Add green beans and cook for 3-4 minutes until crisp-tender. Drain and return to pot. Squeeze lemon juice over beans and toss.
  6. Slice beef tenderloin against the grain. Serve with roasted potatoes, lemon green beans and drizzle with creamy pan sauce.

Recipe Tips

Let the beef rest after searing to keep it juicy.

For extra crispy potatoes, flip them halfway through roasting.
