Step 1: Preheat your oven to 400°F (200°C). This will ensure that your flat breads cook evenly and become perfectly crispy.
Step 2: In a mixing bowl, combine the shredded cheddar and mozzarella cheese. Add in the sour cream, mayonnaise, chopped parsley, salt, and pepper. Mix until all the ingredients are well combined and creamy.
Step 3: Place your flat breads on a baking sheet lined with parchment paper. Use a spatula to spread the cheesy mixture generously over each flat bread, making sure to cover the surface evenly.
Step 4: Place the baking sheet in the preheated oven and bake for about 12-15 minutes, or until the cheese is bubbly and the edges are golden brown. Keep an eye on them to avoid burning.
Step 5: Once baked, remove the cheesy flat breads from the oven and let them cool for a few minutes. This will help the cheese set a bit, making them easier to cut and serve.
Step 6: Using a sharp knife, slice the flat breads into wedges or squares. Serve warm and enjoy the cheesy goodness with your favorite dips or sauces!
