- 1 1/2 teaspoons chili powder
- 3 cloves garlic, minced
- 1 1/2 pounds beef chuck roast, trimmed and cut into 1-inch thick slices
- 1 cup beef stock

- Whisk together vegetable oil, vinegar, lime juice, cumin, chili powder, and garlic in a bowl and pour into a resealable plastic bag. Add the sliced beef, coat with the marinade, squeeze out excess air, and seal the bag. Marinate in the refrigerator for 4 hours or overnight.
- Bring beef to room temperature, about 20 minutes.
- Preheat oven to 350 degrees F (175 degrees C).
- Transfer beef and lime juice marinade to a large baking dish. Add beef stock and cover baking dish with aluminum foil.
