Pastel Azteca: Mexican Tortilla Lasagna with Melted Oaxaca Cheese

Pastel azteca is Mexico's answer to lasagna, and it might be the better one. Toasted corn tortillas stand in for noodles, chicken tinga and roasted guajillo sauce replace the ragù, and a thick blanket of Oaxaca and Chihuahua cheese melts into long, stretchy sheets that pull with every slice.

The whole thing bakes in about twenty minutes once it is layered, which makes it a weeknight casserole that eats like a Sunday project.

This version follows the classic layering method: sauce on the bottom, then repeating rounds of toasted tortillas, smoky shredded chicken tinga, sweet corn and ribbons of Mexican crema. A final layer of tortillas gets buried under three cups of shredded Oaxaca and Chihuahua cheese, and a hot oven turns the whole dish bubbling and golden in twenty minutes.

Because the tortillas are toasted first, the layers stay distinct instead of dissolving into mush, so every square cuts clean and towers on the plate. Both the tinga and the guajillo sauce are treated as made-ahead components here, which is exactly how the dish is handled in Mexican kitchens, and it means the active work is mostly assembling and grating cheese. Garnish with cilantro, slice tall, and serve it steaming.

Ingredients

Why this recipe works

The method works because each layer does a specific job. Toasting the tortillas on a dry comal sets their surface and drives off surface moisture, so they soak up sauce without collapsing; they behave like lasagna noodles that never go gummy.

Spreading sauce under the first layer and between every filling layer keeps the stack lubricated and evenly seasoned from bottom to top, so no slice tastes dry or bland at the edges.

The cheese choice is equally deliberate. Oaxaca cheese melts into long, elastic strands, while Chihuahua cheese browns more readily and adds a buttery note; together they create a lid that stretches when sliced yet holds the layers in place. Baking at 375°F is hot enough to bubble the sauce and brown the top quickly, before the tortillas beneath have time to over-soften, which is why twenty minutes is all the dish needs.

Notes and substitutions

Chicken tinga and roasted guajillo sauce are both made ahead or bought ready: tinga is a cooked, shredded chicken dish, and smooth red enchilada-style guajillo sauce is widely available in jars.

If making them from scratch, do it a day ahead so assembly stays quick, and heat the tinga to 165°F (74°C) before layering. Grate the Oaxaca and Chihuahua cheese from blocks if possible; pre-shredded bags contain starch that can make the top chalky instead of glossy.

A 9x13-inch ceramic or glass baking dish is ideal, and a dry cast-iron skillet or comal handles the tortilla toasting. If crema is hard to find, thin sour cream with a splash of milk until it drizzles. Corn tortillas should be the standard 6-inch size; larger ones work too, just trim or overlap to fit the dish without leaving thick folded edges.

• Oaxaca and Chihuahua cheese: Use all Monterey Jack or a mix of Jack and mild cheddar; the melt stays stretchy and the flavor stays mild enough for the guajillo sauce to lead.
• Mexican crema: Thin sour cream with a tablespoon or two of milk until it drizzles easily, or use crème fraîche thinned the same way.
• chicken tinga: Any seasoned shredded chicken works: fold rotisserie chicken into a few spoonfuls of chipotle sauce or the guajillo sauce to mimic the smoky flavor.
• roasted red guajillo sauce: A smooth red enchilada sauce from a jar stands in well; pick one with guajillo or ancho chiles listed first for a deeper, roasted flavor.
