  • Serve :
  • Let the casserole cool slightly before slicing. Garnish with fresh cilantro and serve with salsa, sour cream, or guacamole on the side.

Notes

Substitute poblano peppers with canned green chiles for a quicker version, though roasting fresh poblanos adds authentic flavor.
Use gluten-free flour for a gluten-free option.
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave.
Freeze individual portions for up to 3 months. Thaw overnight in the refrigerator before reheating.
