A quick and easy recipe featuring tender garlic butter filet mignon paired with crisp-tender roasted asparagus, perfect for special occasions or a comforting solo dinner.

Ingredients

Scale
  • 2 filet mignon steaks (about 6 oz / 170 g each, room temperature)
  • 4 tablespoons unsalted butter (60 g, softened)
  • 3 garlic cloves, minced
  • 2 teaspoons fresh thyme, chopped
  • 1 tablespoon fresh parsley, chopped
  • 2 tablespoons olive oil (extra virgin)
  • 1 bunch asparagus (about 12 oz / 340 g, trimmed)
  • Salt and freshly cracked black pepper, to taste
  • 1/2 lemon, juiced (optional)

Instructions

  1. Prepare the garlic butter: In a small bowl, mix softened unsalted butter, minced garlic, chopped thyme, and parsley until well combined. Set aside at room temperature.
  2. Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper.
  3. Trim woody ends off asparagus (about 1-2 inches). Place on baking sheet, drizzle with olive oil, sprinkle with salt and pepper, and toss to coat evenly. Spread in a single layer.
  4. Roast asparagus in oven for 12-15 minutes, turning halfway through, until crisp-tender and slightly browned.
  5. While asparagus roasts, pat filet mignon steaks dry with paper towels. Season both sides generously with salt and black pepper.
  6. Heat cast iron skillet over medium-high heat until very hot. Add 1 tablespoon olive oil. Sear steaks for 3-4 minutes per side for medium-rare, adjusting time for thickness. Flip gently with tongs.
  7. Reduce heat to medium-low. Add half the garlic butter to skillet, letting it melt and foam. Tilt pan and spoon butter over steaks repeatedly for about 2 minutes to baste.
  8. Remove steaks from pan and place on warm plate. Top each with remaining garlic butter. Let rest for 5 minutes to allow juices to redistribute.
  9. Optional: Squeeze fresh lemon juice over roasted asparagus before serving.
  10. Serve garlic butter filet mignon alongside roasted asparagus. Pour any remaining garlic butter from pan over steak.

Notes

Pat steaks dry before seasoning for better sear. Use medium-low heat when basting garlic butter to avoid burning. Rest steaks for 5 minutes after cooking for juicy results. If asparagus is thin, reduce roasting time by a few minutes. Can substitute green beans or broccolini for asparagus. For dairy-free, use vegan butter substitute.
