Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering, about 2 minutes.
  2. Step 2: Add 10 oz beef tenderloin medallions sliced into 1/2-inch rounds and sear for 2 minutes per side until browned but still pink inside; remove and set aside.
  3. Step 3: In the same skillet, add 3 minced garlic cloves, 1 cup broccoli florets, and 1 thinly sliced small red bell pepper; sauté for 4 minutes until vegetables are crisp-tender and garlic is fragrant.
  4. Step 4: Lower heat to medium and pour in 1/2 cup heavy cream, stirring to combine.
  5. Step 5: Add 1/3 cup grated Asiago cheese and stir continuously for 2-3 minutes until the sauce thickens and coats the vegetables.
  6. Step 6: Return the beef medallions to the skillet, season with 3/4 tsp salt and 1/2 tsp black pepper, and gently toss to warm through for 1 minute before serving.
