Ingredient Quantities
- 2 pounds beef sirloin or chuck, cut into 1 to 1 1/2 inch cubes
- 4 tablespoons unsalted butter
- 1 tablespoon olive oil
- 6 cloves garlic, minced
- 1/2 cup low sodium beef broth
- 2 tablespoons soy sauce
- 1 tablespoon Worcestershire sauce
- 1 tablespoon brown sugar
- 2 tablespoons cornstarch
- 2 tablespoons cold water
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper

- 2 tablespoons chopped fresh parsley for garnish
How to Make this
1. Pat the beef cubes dry and season with kosher salt, black pepper, and dried thyme or Italian seasoning.
2. Heat the olive oil in a large skillet over medium-high heat and sear the beef in batches until browned on all sides, about 2 to 3 minutes per side; transfer seared beef to the slow cooker.
3. In the same skillet, reduce heat to medium, add 2 tablespoons unsalted butter and the minced garlic, and cook until fragrant, about 30 seconds to 1 minute.
4. Pour the garlic butter mixture into the slow cooker with the beef.
5. Add the low sodium beef broth, soy sauce, Worcestershire sauce, and brown sugar to the slow cooker; stir to combine.
6. Cover and cook on low for 4 to 5 hours or on high for 2 to 3 hours, until the beef is tender.
7. About 15 minutes before serving, melt the remaining 2 tablespoons unsalted butter in a small bowl and whisk together the cornstarch and cold water to make a slurry.
8. Stir the butter into the slow cooker, then slowly whisk in the cornstarch slurry to thicken the sauce; cook uncovered for 10 to 15 minutes until the sauce reaches desired thickness.
9. Taste and adjust seasoning with additional kosher salt or black pepper if needed.
10. Garnish with chopped fresh parsley and serve the garlic butter beef bites hot.

High Protein Slow Cooker Garlic Butter Beef Bites Recipe Substitutions and Variations
- 2 pounds beef sirloin or chuck: substitute with flank steak, top round, or boneless skirt steak (similar cook times and protein content)
- 4 tablespoons unsalted butter: substitute with ghee, olive oil, or avocado oil for high heat and rich flavor
- 2 tablespoons soy sauce: substitute with tamari for gluten free, coconut aminos for lower sodium and soy free, or liquid aminos
- 2 tablespoons cornstarch: substitute with arrowroot powder, tapioca starch, or 1 tablespoon all purpose flour mixed with a little extra water to thicken
Pro Tips
– Sear in dry pans and small batches: Make sure the beef cubes are very dry before they hit the hot oil and only brown a few pieces at a time. Crowding the pan cools it down and causes steaming instead of a good crust, which gives you more flavor in the finished dish.
– Rake the garlic timing: Browning garlic a bit in butter gives great aroma, but it can go from golden to bitter fast. Keep the heat moderate, watch closely, and remove the skillet from direct heat as soon as the garlic is fragrant, then transfer to the cooker to finish gently.
– Control tenderness with time and cut choice: Chuck will yield more melt in your mouth bites if cooked a little longer on low, while sirloin stays firmer and benefits from the shorter end of the cooking window. If you prefer fork tender pieces, err toward the longer low setting.
– Thicken with confidence: Mix the cornstarch into cold water first and add it slowly while stirring. If the sauce thickens too much, whisk in a splash of beef broth to loosen it. For silkier richness, stir the final butter in off heat so it melts into the sauce without breaking.
