Making Cheddar Bay Beef Cobbler is simple if you follow these steps:

1. Preheat the Oven: Set your oven to 400°F (200°C).

2. Cook the Beef: In a large skillet over medium heat, brown the ground beef. Drain excess fat if necessary.

3. Add Aromatics: Stir in the diced onion and minced garlic, cooking until softened.

4. Incorporate Vegetables: Add frozen mixed vegetables and stir for about 2 minutes.

5. Pour in Liquid: Add beef broth and Worcestershire sauce, bringing the mixture to a simmer. Season with thyme, black pepper, and salt.

6. Prepare the Filling: Let the mixture cook until slightly thickened, about 5-10 minutes. Stir in shredded cheddar cheese, removing from heat when melted.

7. Make the Biscuit Topping: In a mixing bowl, whisk together flour, baking powder, baking soda, and salt. Cut in cold butter until the mixture resembles coarse crumbs.

8. Add Buttermilk: Pour in the buttermilk and mix until just combined. Do not overmix; the dough should be slightly lumpy.

9. Assemble: Pour the beef mixture into a 9×13 inch baking dish. Drop spoonfuls of biscuit dough evenly over the top.

10. Add Extra Cheese: Sprinkle additional cheddar cheese over the biscuit topping for extra richness.

11. Bake: Place the dish in the preheated oven and bake for 25-30 minutes until the biscuits are golden brown and cooked through.

12. Cool and Serve: Allow the cobbler to cool for 5 minutes before serving. Enjoy this delicious dish warm!
