Beef and cheddar biscuit bake tops savory ground beef in a cheesy sauce with golden biscuits for a hearty family dinner. This protein-rich, budget-friendly casserole is comforting and ready in under an hour.
Preheat oven to 400°F (205°C); grease a 9x13-inch baking dish.
In a large skillet over medium-high heat, brown the ground beef for 5–6 minutes, breaking apart with a spatula. Add onion and cook until softened, about 3 minutes.
Stir in drained tomatoes, salt, black pepper, garlic powder, and dried parsley. Simmer mixture for 3–4 minutes over medium heat to meld flavors. Remove from heat.
Spread the beef mixture evenly in the prepared baking dish; sprinkle 1 cup of shredded cheddar cheese over the beef mixture.
In a mixing bowl, combine flour, baking powder, and 0.25 tsp salt. Cut in cold butter until mixture resembles coarse crumbs. Stir in milk to form a soft dough.
Drop biscuit dough by large spoonfuls over the beef layer, spacing evenly; sprinkle the remaining 0.5 cup cheddar cheese on top.
Bake on the center oven rack for 20–25 minutes, or until biscuits are golden brown and cooked through. Allow to rest for 5 minutes before serving.
