Carne Guisada (South Texas Taqueria Style)

• 2 lbs chuck roast, hand-cut into 1/2-inch cubes (cut your own for the collagen; round works but is leaner and less forgiving)
• 1/3 cup all-purpose flour, for dredging
• 2 teaspoons ground cumin (comino), divided
• Salt, to taste
• Coarse-ground black pepper, to taste (be generous — it's a signature note)
• 2 tablespoons oil or lard
• 2 large green bell peppers, diced (structural — this is what makes the gravy pale and pepper-forward)
• 1 large onion, diced
• 1–2 serrano peppers, minced (moderate heat; seed them for milder)
• 4 cloves garlic, minced
• 2 tablespoons tomato sauce or 1 small tomato, chopped (a little — background acid and color, not a tomato stew)
• 2.5–3 cups beef stock or water, enough to nearly cover
• 1 teaspoon paprika (optional, for warmth and color)

Method

1. 1
   Dredge the beef

   Pat the chuck cubes dry. Toss with the flour, 1 teaspoon of the cumin, a good amount of salt, and plenty of black pepper until lightly coated. The flour on the meat is what thickens the gravy as it braises.

2. 2
   Brown lightly

   Heat the oil or lard in a heavy pot over medium. Brown the dredged beef in batches — but only LIGHTLY, just to set the flour and give a little color. Do not hard-sear to a dark crust; this dish stays pale, not deeply browned. Pull the meat out as each batch is done.

3. 3
   Soften the vegetables

   In the same pot, add a touch more fat if needed and cook the bell pepper, onion, and serrano over medium until soft and the onion is translucent, scraping up any flour stuck to the bottom. Take your time — the bell pepper cooking down is where the flavor and the greenish color come from. Add the garlic in the last minute so it doesn't scorch.

4. 4
   Build the gravy

   Stir in the tomato, the remaining 1 teaspoon cumin, the paprika, and more black pepper. Return the beef and any juices. Add the stock or water to nearly cover — not drown; the flour will thicken it. Stir well to loosen any flour from the bottom into the liquid.

5. 5
   Braise

   Bring to a simmer, then cover and cook low for about 2 hours, stirring occasionally, until the beef is fork-tender and the gravy has thickened to a cohesive, spoon-coating consistency — not chunky, not pureed. If it thickens too much, add a splash of stock; if it's thin, uncover for the last 20–30 minutes to reduce.

6. 6
   Season and serve

   Taste and adjust salt, pepper, and cumin. Serve with Mexican rice, refried or borracho beans, and warm flour tortillas — or spoon into breakfast tacos with egg and potato.
