Preheat the oven to 200°C / 400°F and line a large baking sheet with parchment paper.
Using a 1/4-cup measuring cup, scoop portions of the freshly grated cheddar onto the prepared sheet, spacing them apart; gently spread each into a 4-inch circle.
Bake for 8–10 minutes, until the cheese is fully melted and golden brown at the edges.
Remove from the oven and let cool for a few minutes until safe to handle but still pliable.
Use a spatula to lift each cheese circle and drape it over a greased rolling pin or glass jar to form a taco shell; cool completely before removing and serving.
