Ingredients:
- 5 lbs Ground Beef (80/20 blend)
- 1/2 cup Panko Breadcrumbs
- 1/4 cup Whole or 2% Milk
- 1 large Egg, lightly beaten
- 1/2 medium Onion, very finely minced or grated
- 1 Tbsp Worcestershire Sauce
- 1 tsp Dijon Mustard
- 1/2 tsp Dried Thyme
- 1 tsp Salt
- 1/2 tsp Black Pepper
- 2 Tbsp Olive Oil or Butter (for searing)
- 3 Tbsp Unsalted Butter (for gravy)
- 8 oz Cremini/Button Mushrooms, sliced thinly
- 2 cloves Garlic, minced
- 3 Tbsp All-Purpose Flour
- 2 cups Low Sodium Beef Broth
- 2 Tbsp Heavy Cream (optional)
- 1 Tbsp Fresh Parsley, chopped (for garnish)
Instructions:
- Combine panko breadcrumbs and milk in a small bowl. Let stand for 5 minutes until fully absorbed to create the panade.
- In a large bowl, gently combine the soaked breadcrumbs, ground beef, minced onion, egg, Worcestershire sauce, Dijon, thyme, salt, and pepper. Mix only until just combined; do not overwork.
- Divide the mixture into four equal portions. Gently form into oval, slightly flattened patties (about 3/4 inch thick), creating a slight indent in the centre of each. Chill for 15 minutes if time allows.
- Heat 2 Tbsp of oil or butter in a large, heavy-bottomed skillet over medium-high heat. Sear the patties for 4–5 minutes per side until deeply browned. Remove steaks and set aside on a warm plate.
- Add the remaining 1 Tbsp of butter to the same skillet. Sauté the sliced mushrooms over medium heat until deeply caramelized (about 6–8 minutes). Add minced garlic during the last minute of cooking.
- Sprinkle the flour over the cooked mushrooms. Stir constantly for 1 minute to cook out the raw flour taste, creating a roux.
- Gradually whisk in the cold beef broth, scraping up any browned bits (fond) from the bottom of the pan. Bring to a simmer and cook, stirring occasionally, until the gravy thickens sufficiently (about 5–7 minutes).
- Return the seared steaks gently into the simmering gravy. Cover the skillet loosely, reduce heat to medium-low, and allow the steaks to finish cooking through in the gravy for 8–10 minutes, or until internal temperature reaches 160°F (71°C).
- Stir in the heavy cream (if using). Garnish with fresh parsley and serve immediately, ideally over mashed potatoes.
