Ingredients
- beef sirloin steaks – 4 steaks (about 200 g each)
- onions – 3 large / 450 g, thinly sliced
- butter – 3 tbsp / 42 g
- oil – 2 tbsp / 28 ml
- all-purpose flour – 3 tbsp / 24 g
- beef broth – 1 cup / 240 ml
- red wine – 1/2 cup / 120 ml
- salt – to taste
- black pepper – to taste
- sugar – 1 tsp / 4 g
Instructions
- Season the beef steaks with salt and black pepper.
- Heat 1 tbsp of butter and the oil in a large skillet over medium-high heat.
- Lightly coat the steaks in flour, shaking off any excess.
- Place the steaks in the skillet and sear for 3-4 minutes on each side until browned. Remove from the skillet and set aside.
- In the same skillet, add the remaining butter and the sliced onions. Cook over medium heat, stirring occasionally, until onions are caramelized, about 15-20 minutes.
- Sprinkle sugar over the onions and cook for another 2 minutes.
- Pour in the beef broth and red wine, scraping up any browned bits from the bottom of the skillet. Bring to a simmer and return the steaks to the skillet.
- Simmer for 5-10 minutes, or until the steaks are cooked to your desired level of doneness.
- Serve the steaks topped with the caramelized onions and sauce, alongside traditional German side dishes like spätzle or roasted potatoes.
