# Expert Hints:

01 -
  • The roasted sweet potatoes get caramelized edges that taste almost candy-like against the smoky spices.
  • Everything comes together in under an hour, and most of that time is hands-off roasting.
  • You can prep all the components ahead and let everyone build their own tostadas at the table.
  • It feels indulgent and restaurant-worthy but uses mostly pantry staples you probably already have.
02 -
  • Do not skip the halfway stir when roasting the sweet potatoes or the bottom pieces will burn while the top ones stay pale and soft.
  • Rinsing the black beans really does matter, the canned liquid can make the whole mixture taste metallic and flat.
  • Assemble the tostadas right before serving or the shells will get soggy and lose that satisfying crunch.
03 -
  • Use a box grater to quickly shred any leftover sweet potato into hash browns for breakfast the next morning.
  • If your tostada shells are not crispy enough, pop them in the oven for 3 minutes before assembling to bring them back to life.
  • Double the roasted sweet potatoes and toss the leftovers into grain bowls, tacos, or salads throughout the week.
