In a large bowl, combine ground turkey, breadcrumbs, egg, ketchup, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Mix just until combined, do not overwork.
1 ½ pounds Ground Turkey, 1 Large Egg, 2 tablespoons Ketchup, 1 tablespoon Worcestershire Sauce, ½ teaspoon Garlic Powder, ½ teaspoon Onion Powder, ¾ teaspoon Salt, ½ teaspoon Black Pepper, ½ cup Fine Breadcrumbs
Form into 4 to 6 oval patties, about ¾-inch thick.
Heat olive oil in a large skillet over medium heat. Add patties and cook 4–5 minutes per side, until browned and mostly cooked through.
1 tablespoon Olive Oil
Remove to a plate and set aside (they will finish cooking in the gravy).
In the same skillet, melt butter. Add mushrooms and onions. Cook 6–8 minutes, stirring occasionally, until softened and lightly browned.
2 tablespoons Butter, 8 ounces Mushrooms, ½ Yellow Onion
Sprinkle flour over the mushroom mixture and stir well. Cook for 1 minute.
2 tablespoons All-Purpose Flour
Slowly whisk in the broth, scraping up browned bits from the pan. Add Worcestershire sauce and thyme (if using.) Simmer 3 to 5 minutes until thickened.
Return the turkey patties to the skillet. Spoon gravy over the top. Cover and simmer on low for 8 to10 minutes, or until the internal temperature of the patties reaches 165°F.
Taste the gravy and adjust seasoning if needed.
Salt and pepper to taste
Notes
Serve Salisbury steak with mashed potatoes, buttered noodles, or rice.Store leftover patties and gravy together in an airtight container for up to 4 days.Rewarm on the stove over low heat or use the microwave. Using low sodium broth works well with this recipe. Beef, turkey, chicken, or even vegetable broth will work.
