1-First, preheat the oven to 400°F (200°C) and position the oven rack near the top. Then, set up a cooling rack using dowels supported by blocks or wooden spoons propped on glasses. Next, line a baking sheet with parchment paper (non-waxed).

2-Use a 6-inch ring mold or draw three 6-inch circles on the parchment paper (flip the paper over if using drawn lines). Place about ¼ cup of shredded cheese inside each ring or on each circle, leaving space between each. Bake near the top of the oven for 5-7 minutes until the cheese is melted, bubbly, and the edges are slightly crisp.

3-Cool for 1-2 minutes and dab off excess oil with paper towels. Carefully lift the cheese circles and drape them over the cooling rack or dowels to form taco shell shapes. Let the shells cool for about 15 minutes to firm up, and repeat the baking and shaping process for additional shells as needed.

4-Finally, fill the shells with desired taco fillings and serve. This quick process takes about 25 minutes total, with just 5 minutes of prep, making it perfect for students or working professionals.
