Ingredients

Why this recipe works

The slow cooking process is essential for breaking down the beef chuck roast. By cooking on low heat over an extended period, the collagen in the meat slowly converts into gelatin, which makes the beef exceptionally tender and succulent. This method allows the flavors of the poblano peppers and garlic to permeate the meat deeply, ensuring that every bite is seasoned perfectly from within.

The combination of Mexican crema and queso Oaxaca provides a unique texture and flavor profile that distinguishes this dish from standard shredded beef.

The crema adds a subtle tang that balances the richness of the butter and beef, while the queso Oaxaca brings a mild, milky stretch that thickens the sauce. These ingredients work together to create a cohesive, restaurant-style finish that holds up beautifully in a tortilla.

Notes and substitutions

Beef chuck roast is the ideal cut for this recipe due to its marbling and connective tissue, which respond perfectly to slow cooking. If you cannot find queso Oaxaca, Monterey Jack or low-moisture mozzarella are excellent alternatives that provide similar melting properties.

Ensure the poblano peppers are roasted and peeled properly, as this step is crucial for achieving the characteristic smoky flavor without any tough skin textures.

For the best results, use a standard 6-quart slow cooker. If your slow cooker runs particularly hot, start checking the tenderness of the beef around the 7-hour mark. The butter is a key component for adding richness, so do not omit it.

Feel free to adjust the amount of dried oregano depending on personal preference, though the suggested amount provides a balanced, earthy undertone that complements the sweetness of the corn.

• Mexican crema: Use sour cream mixed with a splash of heavy cream for a similar consistency and tang.
• Queso Oaxaca: Low-moisture mozzarella or Monterey Jack can be used as a melting substitute.
