Method
- Season the sirloin slices with salt and pepper.
- Heat olive oil in a large skillet or Dutch oven over medium-high heat.
- Sear the beef in batches, being careful not to overcrowd the pan. Sear for about 1-2 minutes per side, until browned. Remove the beef and set aside.
- Add the sliced onion to the skillet and cook until softened, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant.
- Pour in the beef broth and red wine (if using), scraping up any browned bits from the bottom of the pan. Add the Worcestershire sauce, dried thyme, and bay leaf. Bring to a simmer.
- Return the seared beef to the skillet. Reduce heat to low, cover, and simmer for 30-45 minutes, or until the beef is very tender.
- While the beef is simmering, prepare the gravy. In a separate saucepan, melt the butter over medium heat.
- Whisk in the flour and cook for 1-2 minutes, stirring constantly, to create a roux.
- Gradually whisk in the beef broth and red wine (if using), ensuring no lumps form. Bring to a simmer and cook until the gravy has thickened, about 5-7 minutes. Season with salt and pepper to taste.
- Remove the bay leaf from the beef mixture.
- Pour the gravy over the beef and stir gently to combine.
- Serve the beef and gravy over toasted bread. Garnish with fresh parsley and a side of mashed potatoes, if desired.
Notes
For a richer gravy, use bone broth instead of regular beef broth. You can also add a splash of heavy cream to the gravy at the end for extra richness. Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave.
