  • 5 tablespoons unsalted butter
  • 1 large onion, diced
  • 2 ribs celery, diced
  • 3 cloves garlic, minced
  • 5 tablespoons unbleached all-purpose flour
  • 2 cups turkey stock
  • 1/2 cup whole milk
  • 1 ½ tablespoons Stubb’s Chicken Spice Rub
  • 2 teaspoons fresh thyme, minced (or 1 teaspoon dried thyme)
  • ½ tablespoon fresh sage, minced (or 1 teaspoon dried sage)
  • 3 cups shredded leftover turkey
  • 1 (16-ounce) bag frozen mixed vegetables
  • 3-4 cups leftover mashed potatoes


  1. Preheat oven to 375 degrees F.
  2. Heat butter in a large sauce pan over medium-high heat. Add onions, cook for 6-7 minutes or until translucent. Add celery and cook for 3-4 minutes. Add garlic and cook for an additional 30 seconds to 1 minute.
  3. Stir in flour, stirring constantly until a thick, golden roux is formed, about 2-3 minutes. Stirring constantly, stir in turkey broth and milk. Simmer for 4-5 minutes, stirring occasionally, or until gravy is thickened. Stir in Stubb’s Chicken Spice Rub, thyme, sage, turkey and mixed vegetables. Simmer, stirring occasionally, for 5-6 minutes.
  4. Pour prepared Shepherd’s Pie filling into a 9x13-inch baking dish. Spread prepared mashed potatoes evenly over the meat and vegetable filling. Bake in preheated 375 degree F oven for 20-25 minutes or until potatoes start to brown and casserole is heated through.
