Impossibly Easy Mini Blue Cheeseburger Pies
- Heat oven to 375°F Spray 12 regular-size muffin cups with cooking spray.
- In 10-inch skillet, cook beef and onion over medium-high heat 5 to 7 minutes, stirring frequently, until beef is thoroughly cooked; drain. Cool 5 minutes; stir in blue cheese and Worcestershire sauce.
- In medium bowl, stir baking mixture ingredients with whisk or fork until blended. Spoon 1 scant tablespoon baking mixture into each muffin cup. Top with about 1/4 cup burger mixture. Spoon 1 tablespoon baking mixture onto burger mixture in each muffin cup.
- Bake 25 to 30 minutes or until toothpick inserted in center comes out clean and tops are golden brown. Ten minutes into baking, carefully open oven and sprinkle 1/2 tablespoon French-fried onions on top of each muffin. Close oven door and finish baking. Cool 5 minutes. With thin knife, loosen sides of pies from pan; remove from pan and place top sides up on cooling rack. Cool 10 minutes longer, and serve.
