Preparing the Ingredients
Preheat oven to 325 degrees.
While oven is preheating, Turn on stove to high and start heating a large frying pan. Crumble the ground beef into the heated pan. Use a wooden spoon to break up the ground beef. Let the beef cook for 2 minutes.
While beef is cooking, prepare a cookie sheet with parchment paper on it. Place biscuits on top of the parchment paper. Bake the biscuits for about 16 minutes in the preheated oven, or until nice and brown.
Add the taco seasoning into the ground beef. Stir and continue using the wooden spoon to break up the beef chunks.
