Creating delicious Slow Cooker Garlic Beef Bites is straightforward if you follow these steps:

1. Prep the Beef: Cut the beef chuck roast into bite-sized pieces, trimming any excess fat.
2. Sear the Meat: In a skillet, heat the olive oil over medium-high heat. Add the beef pieces in batches and sear until browned on all sides. This step adds depth of flavor.
3. Prepare the Sauce: In a bowl, mix the minced garlic, beef broth, soy sauce, brown sugar, Worcestershire sauce, black pepper, onion powder, and red pepper flakes (if using).
4. Combine in Slow Cooker: Place the seared beef into the slow cooker. Pour the sauce mixture over the beef, ensuring all pieces are coated.
5. Cook: Cover and cook on low for 5 to 6 hours or on high for 3 to 4 hours, until the beef is tender.
6. Thicken the Sauce (Optional): If you prefer a thicker sauce, combine cornstarch with a little water to make a slurry. Stir this into the slow cooker about 30 minutes before serving.
7. Garnish: Once done, taste and adjust seasoning if necessary. Before serving, garnish with chopped green onions for a fresh touch.

These simple steps will guide you in creating these incredible bites effortlessly.
