Recipe Instructions:
2 pounds chuck roast, cut into 1-inch pieces
1 tablespoon extra-virgin olive oil
Kosher salt and freshly cracked black pepper
1 pound ground beef
1 large onion, diced
2 bell peppers, diced
2 cups diced zucchini
1 cup mushrooms, roughly chopped
5 garlic cloves, minced
1 (28-ounce) can tomato sauce
1 (15-ounce) can fire-roasted tomatoes, diced
1 (4-ounce) can mild green chiles
2 cups beef stock
2 bay leaves
1 tablespoon garlic powder
¼ to ⅓ cup chili powder
2 tablespoons cumin
Jalapeños, diced, for serving
Avocado, diced, for serving
Cilantro, stems removed, for serving
Green onions, chopped, for serving
Heat olive oil in a large skillet (or in your slow cooker if it has a browning mode) over medium-high heat. Generously season the chuck roast with salt and pepper. Once the oil is glistening, add chuck roast to the skillet and brown on all sides. Transfer to a plate.
Place the beef in the same skillet over medium-high heat. Cook, breaking it up with a wooden spoon, until browned, about 8 minutes. Transfer the beef to a colander set over a bowl to drain off the fat.
Add the browned chuck roast and ground beef, onion, bell peppers, zucchini, mushrooms, garlic, tomato sauce, fire-roasted tomatoes, green chiles, beef stock, bay leaves, garlic powder, chili powder, and cumin to the slow cooker. Cook on HIGH for 4 hours on or on LOW for 8 hours.
Stir, breaking up any large pieces of ground beef, and adjust the salt and pepper to taste.
Serve family-style with slivered jalapeños, avocados, cilantro, and green onions. Enjoy!
