Method
- In a large bowl, combine the ground beef, breadcrumbs, egg, chopped onion, minced garlic, Worcestershire sauce, ketchup, dried thyme, salt, and pepper.
- Use your hands to gently mix the ingredients until just combined. Be careful not to overmix.
- Divide the mixture into 4-6 equal portions and shape them into oval-shaped patties, about ¾ inch thick.
- Heat a tablespoon of olive oil in a large skillet over medium-high heat.
- Once the oil is hot, add the patties and sear them for 2-3 minutes per side, until browned. Don't worry about cooking them all the way through at this point.
- Remove the patties from the skillet and set them aside.
- In the same skillet, melt the butter over medium heat.
- Add the sliced onion and cook until softened, about 5 minutes.
- Then, add the sliced mushrooms and minced garlic and cook until the mushrooms are tender and browned, about 5-7 minutes.
- Sprinkle the flour over the vegetables and cook for 1-2 minutes, stirring constantly, until the flour is lightly browned.
- Gradually whisk in the beef broth, making sure to scrape up any browned bits from the bottom of the skillet.
- Add the Worcestershire sauce, Dijon mustard, dried thyme, salt, and pepper.
- Bring the gravy to a simmer, then reduce the heat to low and let it simmer for 5-7 minutes, or until it has thickened to your desired consistency.
- Gently place the seared patties back into the skillet with the gravy.
- Cover the skillet and let the patties simmer in the gravy for 10-15 minutes, or until they are cooked through and the gravy has thickened even more. Make sure the internal temperature of the patties reaches 160°F (71°C).
Notes
Don't overmix the patties. Adjust the gravy thickness by adding a cornstarch slurry for a thicker gravy or more beef broth for a thinner gravy. Taste and adjust seasoning as needed. For a richer gravy, add a splash of red wine after sauteing the vegetables. Store leftovers in an airtight container in the refrigerator for up to 3-4 days. You can freeze the patties or the cooked Salisbury steak for up to 2-3 months.
