Regardless of what you're putting into them, or whether you favor flour or corn tortillas, your tortillas will always be best if they're kept fresh and warm throughout the meal. You could stack them up in a towel in a warm oven, but going back and forth from the table is inconvenient. You're much better off to use a taco warmer: It takes just moments in the microwave or a few minutes in the oven, and then keeps your tacos warm and flexible for up to an hour.

Line your tortilla warmer with paper towels and place a stack of tortillas inside, one at a time, to prevent sticking and to allow heat to pass between them.

Place a microwave-safe tortilla warmer in the microwave and heat on high for about 15 seconds for every 4 tortillas. Continue microwaving in 15-second intervals, if necessary until the tortillas have warmed to your liking. Keep in mind that corn tortillas take slightly longer than flour tortillas to warm.

Remove the tortilla warmer from the microwave, but keep the lid on. You can place it on the table on a trivet so people can grab a tortilla as they need it. Tortilla warmers can typically keep tortillas warm for up to an hour.
