# How-To Steps:

# Expert Suggestions:

01 -
  • Every bite delivers smoky, sweet, creamy, and tangy flavors all at once without any complicated techniques.
  • You can roast the sweet potatoes while you answer emails or fold laundry, then assemble everything in under five minutes.
  • It uses pantry staples and one fresh vegetable, so you can make it even when the fridge is looking bare.
02 -
  • If you crowd the sweet potato cubes on the baking sheet, they'll steam instead of caramelize, so give them space to breathe.
  • Lime juice added off the heat keeps the cilantro bright green and the beans from tasting cooked-out and dull.
  • Assemble tostadas just before eating or the shells will get soggy from the beans and lose their crunch.
03 -
  • Use a rimmed baking sheet so the olive oil doesn't drip into your oven and smoke.
  • If your tostada shells are thin and fragile, double them up so they don't crack under the toppings.
  • Taste the bean mixture before you assemble; a little extra lime or salt at the end can make all the difference.
