๐Ÿ“ About This Recipe

Arrumbado is a comforting, rustic Mexican treasure that translates literally to 'piled up' or 'tossed together,' embodying the heart of home-style Latin soul food. This savory bake layers crisp-fried corn tortillas with a robust, smoky tomato-guajillo sauce, crumbled spicy chorizo, and a molten blend of Mexican cheeses. It is the perfect marriage of a chilaquil-style texture and an enchilada bake, offering a satisfying crunch and a deep, complex heat that warms the spirit.

๐Ÿฅ— Ingredients

The Sauce (Salsa Roja)

  • 4 pieces Guajillo Chiles (stems and seeds removed)
  • 1.5 lbs Roma Tomatoes (ripe, halved)
  • 1/2 piece White Onion (roughly chopped)
  • 3 cloves Garlic (peeled)
  • 1 teaspoon Chicken Bouillon or Salt (to taste)
  • 1/2 teaspoon Mexican Oregano (dried)

The Filling & Layers

  • 18-20 pieces Corn Tortillas (stale tortillas work best, cut into quarters)
  • 12 ounces Mexican Chorizo (casing removed)
  • 1/2 cup Vegetable Oil (for frying tortillas)
  • 2 cups Queso Oaxaca (shredded or pulled into strings)
  • 1/2 cup Cotija Cheese (crumbled)
  • 1 can Black Beans (15oz, drained and rinsed)

For Garnish

  • 1/2 cup Crema Mexicana (or sour cream thinned with milk)
  • 1/4 cup Fresh Cilantro (finely chopped)
  • 1/4 piece Red Onion (thinly sliced into rings)
  • 1 piece Avocado (sliced)

๐Ÿ‘จโ€๐Ÿณ Instructions

  1. 1

    Preheat your oven to 375ยฐF (190ยฐC). Lightly grease a 9x13 inch baking dish with oil or butter.

  2. 2

    In a dry skillet over medium heat, toast the guajillo chiles for 1-2 minutes until fragrant but not burnt. Place them in a bowl of hot water to soak for 10 minutes.

  3. 3

    In the same skillet, roast the tomatoes, white onion, and garlic until charred in spots. Transfer these to a blender.

  4. 4

    Add the soaked chiles (discard soaking water), oregano, and bouillon to the blender. Process until the sauce is completely smooth. If too thick, add 1/4 cup of water.

  5. 5

    Heat a small amount of oil in a saucepan. Pour in the blended sauce and simmer for 10 minutes on low heat to deepen the flavors. Set aside.

  6. 6

    In a separate large skillet, cook the chorizo over medium-high heat, breaking it up with a spoon until browned and slightly crispy. Remove the chorizo with a slotted spoon, leaving the flavorful fat in the pan.

  7. 7

    Add the vegetable oil to the chorizo fat. Working in batches, fry the tortilla quarters until they are golden and semi-crispy (not as hard as a chip). Drain on paper towels.

  8. 8

    Begin assembly: Spread a thin layer of the red sauce on the bottom of the prepared baking dish.

  9. 9

    Layer half of the fried tortillas over the sauce. Top with half of the cooked chorizo, half of the black beans, and a generous handful of Oaxaca cheese.

  10. 10

    Drizzle more sauce over the layer. Repeat with the remaining tortillas, chorizo, and beans.

  11. 11

    Pour the remaining sauce evenly over the top, ensuring all tortillas are touched by sauce. Finish with the remaining Oaxaca cheese and the crumbled Cotija.

  12. 12

    Cover the dish with foil and bake for 15 minutes. Remove the foil and bake for another 10-15 minutes until the cheese is bubbly and starting to brown.

  13. 13

    Remove from the oven and let rest for 5 minutes. This allows the tortillas to absorb just enough sauce without becoming mushy.

  14. 14

    Garnish with a zigzag of Crema Mexicana, fresh cilantro, red onion rings, and avocado slices before serving warm.

๐Ÿ’ก Chef's Tips

For the best texture, use 'day-old' tortillas as they absorb less oil and hold their shape better during baking. If you cannot find Queso Oaxaca, a mix of Mozzarella and Monterey Jack provides a similar melt and stretch. Do not skip frying the tortillas; this creates a barrier that prevents the casserole from becoming a soggy mass. Adjust the heat by adding 1-2 chiles de รกrbol to the sauce if you prefer a spicier kick. Make it ahead by preparing the sauce and chorizo a day early, then assemble and bake just before serving.

๐Ÿฝ๏ธ Serving Suggestions

Serve alongside a crisp green salad with a lime-vinaigrette to cut through the richness. A side of Mexican red rice (Arroz Rojo) is the traditional accompaniment for a full meal. Pair with a cold Hibiscus Tea (Agua de Jamaica) or a crisp Mexican Lager. For brunch, top individual servings with a fried egg (sunny side up). Serve with extra lime wedges on the side to brighten the smoky flavors.
