Skillet Beef Potpie with Buttermilk Biscuits

Preheat oven to 400 degrees F.

Heat oil in a large ovenproof skillet over medium-high heat. Add beef and cook, breaking it up with a wooden spoon, until browned and cooked through, 4 to 7 minutes. Add garlic, mustard and 3/4 teaspoon salt; cook, stirring, for 1 minute. Stir in onions, peas and carrots; cook, stirring frequently, until the vegetables are hot, about 4 minutes. Sprinkle the mixture with 3 tablespoons flour; cook, stirring, for 1 minute. Add broth and cook, stirring occasionally, until the mixture is slightly thickened, about 10 minutes more. Stir in parsley.

Meanwhile, combine the remaining 1 cup flour, baking powder and the remaining 1/4 teaspoon salt in a medium bowl. Rub butter into the flour to create a coarse mixture. Stir in buttermilk and mix until just combined. Place heaping tablespoonfuls of the batter on top of the beef mixture to make 12 biscuits.

Transfer the pan to the oven. Bake until the biscuits are golden brown and cooked through, 15 to 18 minutes. Garnish with more parsley, if desired.
