Line a cookie sheet with parchment paper. Place ¼ cup of cheese 2 inches apart. Press into a circle.
Bake for 5-7 minutes, or until the edges begin to turn brown.
Cool for 2-3 minutes. Balance a wooden spoon on top of 2 cups. Hang cheese on wooden spoon handle. Cool completely before removing.
Brown ground beef in a skillet until no longer pink. Stir in cumin, chili powder, onion powder, garlic powder, and salt. Pour in water, and cook 4-5 minutes or until evaporated.
Fill taco shells with ground beef and your favorite toppings.
Notes
Ingredient Notes
Use freshly grated cheese. Store-bought shredded cheese has fillers that can interfere with melting. Avoid low-fat or fat-free cheese. You can use any hard cheese that melts. I prefer cheddar, but Colby, Monterrey Jack, Mozzarella, or even Pepper Jack would be good.
Ground Beef: Use lean ground beef to avoid an overly greasy filling. I like using 90% lean.
Chili Powder: Add more less of this depending on how spicy you like it.
Tips
Set up in advance: I like to set up 3 or 4 wooden spoons on top of cups so I can hang them within a few minutes of pulling them out of the oven.
Use nonstick foil or parchment paper to ensure the cheese doesn't stick to your baking sheet.
Make them all the same size so they all finish baking at the same time. I like to use my biscuit cutter as a guide and fill it with ¼ cup of cheese. An egg mold would work, too.
