Ingredients:
- 2 lb (900 g) beef chuck, trimmed and cut into 1–1½ inch (2.5–3.8 cm) cubes (use leaner chuck or 93% lean stew beef for a 'skinny' version)
- 1–2 tsp kosher salt (adjust to taste)
- 1 tsp freshly ground black pepper
- 1 tbsp olive oil (15 mL) — optional, for searing
- 1 large yellow onion, diced (about 1½–2 cups / 225–300 g)
- 1 large green bell pepper, seeded and chopped (about 1 cup / 150 g)
- 3 cloves garlic, minced (about 1 tbsp / 9 g)
- 1 (14 oz / 400 g) can diced tomatoes (undrained)
- 1 (8 oz / 225 g) can tomato sauce (or 3/4 cup / 180 mL crushed tomatoes)
- 1½ cups (360 mL) low-sodium beef broth (or chicken broth)
- 1 tbsp ground cumin (8 g)
- 1 tsp dried oregano (1 g) — preferably Mexican oregano
- 1–2 tsp chili powder (optional, 2–4 g) or smoked paprika for milder smoky flavor
- 1 bay leaf
- 1 tbsp Worcestershire sauce (15 mL) or 1 tsp low-sodium soy sauce (5 mL) — optional
- 1–2 tbsp fresh lime juice (15–30 mL), to finish
- 2 tbsp chopped fresh cilantro (optional, for garnish)
- Salt and pepper to taste before serving
- Optional thickener: 1–2 tbsp cornstarch + 2 tbsp cold water (slurry) OR 2 tbsp masa harina mixed with 1/4 cup warm water
Instructions:
- Pat the beef dry and season all over with 1–2 teaspoons kosher salt and 1 teaspoon freshly ground black pepper; chop the onion and bell pepper and mince the garlic.
- Optional but recommended — heat 1 tablespoon olive oil in a large heavy skillet over medium-high heat and brown the beef in batches until well-browned on all sides (about 2–3 minutes per side); transfer browned beef to the slow cooker.
- Add the diced onion, chopped bell pepper and minced garlic to the slow cooker around and over the beef.
- Pour in the diced tomatoes with their juices and the tomato sauce, then add 1½ cups low-sodium beef broth. Stir in 1 tablespoon ground cumin, 1 teaspoon dried oregano, 1–2 teaspoons chili powder or smoked paprika, 1 bay leaf, and 1 tablespoon Worcestershire sauce or 1 teaspoon soy sauce if using; gently combine.
- Cover and cook on LOW for 6–8 hours or on HIGH for about 4 hours, until the beef is fork-tender and easily pulls apart.
- If the sauce is thin, mix 1–2 tablespoons cornstarch with equal cold water (or 2 tablespoons masa harina with 1/4 cup warm water) and stir the slurry into the slow cooker; set to HIGH and cook 10–20 minutes until the sauce thickens. Remove the bay leaf.
- Stir in 1–2 tablespoons fresh lime juice, adjust salt and pepper to taste, and garnish with chopped cilantro. Serve over rice, with warm tortillas, or alongside beans.
