Begin by preheating your oven to 450°F (232°C). A hot oven is essential for achieving that perfect rise in your biscuits.
In a large mixing bowl, combine the Bisquick mix, garlic powder, sugar, and parsley flakes. Stir the dry ingredients until they're well distributed.
Next, slowly pour in the buttermilk while stirring gently. Aim to combine until just mixed. Overmixing can lead to tough biscuits, and we definitely want light and fluffy results.
Using a floured surface, turn out the dough. Lightly knead it for about 30 seconds. Then, pat it down to a thickness of about ½ inch. Use a biscuit cutter or a glass to cut out rounds. Do not twist when cutting; just press straight down to maintain that fluffy texture.
Place the biscuits on a lined baking sheet. They can be placed close together (for soft edges) or spaced apart (for crusty edges). Brush the tops with melted butter.
Pop them into the oven for 8-10 minutes, or until they are golden brown on top. You’ll know they’re done when your kitchen fills with that irresistible smell.
Remove from the oven and brush with a bit more melted butter if desired. Serve warm with your favorite toppings or enjoy them plain.
