Stuffed Chili Rellenos

This layered stuffed chile rellenos casserole skips the tricky deep-fry step that makes traditional rellenos a pain and turns the dish into an easy bake-and-serve. Whole canned green chiles form top and bottom “blankets” with crab, shrimp, and Monterey Jack cheese sandwiched in between, then the whole thing gets a light Bisquick-egg custard poured over and baked slow at low heat until set.

The seafood-cheese combo is what makes this version stand out from standard cheese-only rellenos. Crab adds briny sweetness, shrimp contributes texture, and the sharp aged cheddar on top gives the finished casserole a tangy, golden-brown lid. Dusting the shredded cheese with a small amount of flour is a classic anti-clumping trick so it distributes evenly through the filling instead of forming gummy lumps. The two-temperature bake (high blast, then slow-and-low) sets the bottom layer before the wet custard goes on, then cooks the whole thing gently without breaking the eggs.

Chef Tips

• Open each chile and lay it flat. Tears are fine, overlapping pieces cover any gaps. Butterflying creates maximum surface contact with the filling.
• Dry-pat drained chiles with paper towels before layering. Wet chiles dilute the custard and leave you with a watery casserole.
• Cover with foil for the low-temperature bake. Uncovered, the top cheese browns too fast before the custard sets.
• Let rest 10 minutes before slicing. A warm custard needs time to firm up, and cutting too early means the filling slumps out of shape.

Variations

• Use cooked diced chicken instead of seafood for a less expensive weeknight version.
• Swap canned chiles for roasted, peeled fresh poblanos for deeper chile flavor.
• Top with fresh pico de gallo and avocado slices after baking for a cooler, contrasting finish.
