Preheat your oven to 350°F (175°C).

Brown the ground beef in a skillet over medium heat until no longer pink, about 5-7 minutes. Drain excess fat.

Sauté the chopped onion and minced garlic in the same skillet for 2-3 minutes until fragrant.

Sprinkle the all-purpose flour over the beef mixture and stir well. Gradually whisk in the beef broth and milk until thickened, about 3-5 minutes.

Season with salt, pepper, and thyme, mixing thickly until blended and creamy.

Cut the refrigerated biscuits into quarters and fold them into the gravy mixture.

Pour the mixture into a greased baking dish and spread evenly. Bake for 25-30 minutes until golden brown and fluffy.
