Method
- Pat the sirloin tips dry, then season them with the kosher salt and black pepper.
- Heat 1 tablespoon of the vegetable oil in a 12-inch skillet over medium-high heat. Brown half the beef, turning occasionally, for 4 to 5 minutes, then transfer it to a 6-quart slow cooker.
- Add the remaining oil to the skillet and brown the rest of the beef.
- Add the yellow onion and green bell pepper to the skillet and cook for 4 to 5 minutes, until softened.
- Stir in the garlic, tomato paste, chili powder, ground cumin, smoked paprika, dried oregano, and cayenne pepper, and cook for 1 minute.
- Stir the crushed tomatoes and low-sodium beef broth into the skillet, scraping up any browned bits.
- Pour the tomato mixture over the beef in the slow cooker and stir to combine.
- Cover and cook on LOW for 4 to 5 hours or HIGH for 2 to 3 hours, until the beef is fork-tender.
Notes
Brown the beef in batches so it sears rather than steams. Refrigerate leftovers for 3 to 4 days or freeze them; use certified gluten-free beef broth if needed.
