Instructions
- Step 1: Pat cube steak dry with paper towels and season both sides with salt and pepper. Heat 1 tbsp olive oil in a skillet over medium-high heat. Add steak and cook for 3 minutes per side until golden brown and cooked through; remove and set aside.
- Step 2: Add 1 tbsp butter to the skillet, then stir in thinly sliced onions. Cook for 15 minutes over medium-low heat, stirring occasionally, until onions are deeply caramelized and golden brown. Add balsamic vinegar and cook for 2 minutes until evaporated.
- Step 3: Stir in beef broth, soy sauce, Dijon mustard, and garlic powder. Bring to a simmer and cook for 8 minutes until sauce reduces by half and thickens slightly. Return steak to the skillet and spoon gravy over it. Cook for 2 more minutes until steak is heated through and coated in sauce, then serve immediately with extra gravy.
