Bolognese Pie with Biscuit Topping

Preheat oven to 425 degrees. Make the meat base: Heat oil in a 10-inch ovenproof skillet over medium-high heat. Add zucchini; cook, stirring, until golden and just beginning to soften, 4 to 5 minutes. Stir in leftover Bolognese Sauce until warmed through, about 3 minutes. Cover to keep warm.

Make the biscuit topping: In a large bowl, whisk together flour, baking powder, thyme, and salt. Using a pastry blender, a fork, or your fingers, work in butter until pea-size clumps form. Stir in milk and cheese until dough just comes together.

Spoon dough over beef mixture in 8 small mounds, about 1 inch apart. Bake until meat mixture is bubbling and topping is golden brown (a toothpick inserted in center of a biscuit should come out clean), about 25 minutes. Serve immediately.
