# Expert Tips:

01 -
  • Every bite has texture contrast: creamy avocado against caramelized sweet potato and a satisfying crunch from the shell.
  • It feels indulgent but uses pantry staples, so you can throw it together without a special shopping trip.
  • The limey bean mixture brightens everything and makes the whole plate feel summery, even in winter.
02 -
  • Do not overcrowd the baking sheet or the sweet potatoes will steam instead of caramelize, and you will miss out on those crispy edges.
  • Stir the lime juice into the beans off the heat so the acidity stays bright and does not cook away.
  • Assemble the tostadas right before eating or the shells will absorb moisture from the beans and lose their crunch.
03 -
  • Use a well-seasoned cast iron skillet to crisp store-bought tostada shells in the oven for a minute before assembling if they have gone soft.
  • Squeeze the lime over the avocado slices right before serving to keep them from browning and add an extra pop of acidity.
  • Taste the bean mixture before assembling and adjust the salt; canned beans vary in saltiness, and you want bold flavor in every bite.
