Tender pan-seared beef patties smothered in a savory mushroom and onion gravy. This easy comfort food dinner comes together in one skillet in under 30 minutes.
In a large bowl, gently mix together the ground sirloin, egg, Worcestershire sauce, breadcrumbs, garlic powder, onion powder, salt, and pepper until just combined. Do not overmix.
Divide the mixture into 4 equal portions and shape into 1-inch thick patties.
Heat vegetable oil in a large skillet over medium heat.
Add the patties and cook for 2 to 3 minutes per side until browned. Remove to a plate and cover with foil.
Add the onions and mushrooms to the skillet. Cook for 2 to 3 minutes until softened.
Sprinkle flour over the vegetables and stir to coat. Cook for 1 minute.
Slowly pour in the beef broth, stirring constantly and scraping up the browned bits from the bottom of the pan.
Simmer for 3 to 5 minutes until the gravy begins to thicken.
Return the patties to the skillet and spoon gravy over the top. Simmer on low for 10 minutes until the beef is cooked through (160°F internal temperature) and the gravy is thickened.
Notes
Meat ratio: Use ground sirloin with a 90/10 or 85/15 lean-to-fat ratio for the best texture.
Keep it tender: Mix the meat gently and avoid pressing down on the patties while cooking.
No mushrooms? Leave them out for a simple onion gravy.
Doneness: The patties are done when they reach 160°F internally. A slight pink center is fine at that temperature.
Storage: Refrigerate leftovers for up to 5 days or freeze for up to 3 months.
Reheating: Warm in the microwave or in a skillet over medium-low heat. Add a splash of broth if the gravy has thickened.
