Ingredient Notes & Substitutions
Roasted Poblanos
The smoky char from roasting gives the dish its signature flavor. For extra smokiness, grill instead of oven-roast.
Substitutions: Use Anaheim peppers for milder flavor, or poblano powder for a dry rub version.
Cheese Blend
Monterey Jack melts smoothly while cheddar adds richness. For vegan version, use nutritional yeast and cashew cheese.
Substitutions: Substitute with Oaxaca or queso fresco for authentic Mexican flavor.
Egg Mixture
The custard creates a light, fluffy texture that complements the roasted peppers. For gluten-free version, use certified GF milk.
Substitutions: Use egg substitute for vegan version, or add ½ cup diced tomatoes for a vegetarian option.
Spices
Cumin and chili powder provide the essential Mexican flavor profile. Add ½ tsp of smoked paprika for extra depth.
Substitutions: Use ground coriander instead of cumin for a different flavor note.

Make-Ahead Instructions & Storage
Make-Ahead Tips
Assemble casserole up to 24 hours in advance. Cover and refrigerate until ready to bake.
Refrigerator Storage
Store leftovers in an airtight container for up to 3 days. Reheat in oven at 350°F (175°C) until warmed through.
Freezer Storage
Freeze unbaked casserole for up to 3 months. Thaw overnight in refrigerator before baking.
Reheating Instructions
For best results, reheat in oven rather than microwave to maintain texture. Cover with foil to prevent over-browning.
Troubleshooting & Common Questions
Q: Can I use frozen poblanos?
A: Yes, but thaw completely first. Frozen poblanos may release more moisture, so pat dry before using.
Q: How do I prevent the cheese from burning?
A: Cover with foil during baking and remove for the last 2 minutes to allow browning.
Q: Can I make this in a smaller dish?
A: Yes, but baking time will increase by 10-15 minutes. Check for doneness with a toothpick.
Q: Why isn't the casserole puffinging?
A: Ensure oven is fully preheated. The eggs need high heat to create the puffing. Avoid opening oven door during baking.
