Can I make shrimp flautas ahead of time?
Yes. Roll and fill flautas up to 4 hours ahead, cover with plastic wrap, and refrigerate. Fry just before serving for best crispness. You can also freeze unbaked flautas for up to 2 weeks; fry from frozen, adding 1–2 minutes to cook time.
Why use two corn tortillas instead of one?
Double tortillas prevent tearing during rolling and frying, create a sturdier structure, and give you that characteristic extra-long shape. They also reduce the chance of filling leaking out into the oil.
What oil temperature should I use for frying?
Heat oil to 350–375°F (175–190°C). Use a thermometer for accuracy. Oil that's too cool produces soggy, greasy flautas; oil that's too hot burns the exterior before the filling heats through.
Can I use a different cheese instead of Oaxaca?
Yes. Mozzarella, queso fresco, or a blend of Monterey Jack and cotija work well. Oaxaca melts smoothly and has a mild flavor that won't overpower the shrimp, so adjust seasoning if you swap it out.
How do I know when the flautas are done frying?
They're ready when deep golden brown and crispy, about 2–3 minutes total (1–1.5 minutes per side). The tortillas should sound crispy when you tap them, and any filling that peeks out at the seams should be opaque.
