What One Corn Tostada Shell Means
A tostada shell is a crisp corn tortilla base used for an open-faced meal or snack. This USDA record is for the shell itself, with a typical serving of one piece at approximately 12.3 g. It does not describe the complete tostada once beans, meat, cheese, avocado, crema or salsa are added.
Nutrition per Shell
One shell contains 58 calories, 8 g carbohydrate, 3 g total fat and 0.8 g protein. It also records 0.7 g dietary fiber, 1 g saturated fat, 81 mg sodium, 0 g total sugar and 0 mg cholesterol. The page records 9 mg calcium, 29 mg potassium and 0.2 mg iron per shell.
How Toppings Change the Meal
Two shells would provide approximately 116 calories, 16 g carbohydrate, 6 g fat and 1.6 g protein before toppings. Beans, chicken, beef, cheese, avocado, oil and sauces each add their own calories and sodium. For a useful meal estimate, count the shell by piece and weigh the toppings instead of treating the nutrition panel as a full tostada.
Baked, Fried and Packaged Versions
Corn shells from different brands or restaurants may be baked or fried and may use different oil and salt amounts. This entry should not be used interchangeably with a soft corn tortilla or a flavored snack chip. Check the package label when the shell weight, cooking method or serving count differs from approximately 12.3 g per piece.
Storage and Pairing
Keep packaged shells sealed in a cool, dry place and follow the package's best-by guidance so they remain crisp. Beans, vegetables and a protein are common topping choices, but pairing changes the finished meal rather than the shell's recorded values. Discard shells with visible mold, moisture damage or an off odor.
