For a crispier top, broil the casserole for 1 to 2 minutes at the end, watching closely to prevent burning. If using flour tortillas, cut back slightly on layers to avoid a doughy texture, and toast them briefly in a dry pan to reduce sogginess. You can add 1/2 pound cooked, seasoned ground turkey or beef for a meat option, or swap in pinto beans for variety. To make ahead, assemble up to step 10, cover, and refrigerate up to 24 hours; add 5 to 10 minutes to the covered bake time if chilled. Leftovers reheat well in a 350°F oven for 10 minutes or in a skillet with a splash of water to re-crisp the edges.
