Ingredients Overview
Each ingredient in this recipe plays a role in keeping it flavorful, tender, and packed with protein.
Beef Chuck Roast or Sirloin
High in protein and ideal for slow cooking. Chuck becomes incredibly tender over time, while sirloin offers leaner bites that still retain juiciness. Cut into 1½-inch cubes for even cooking.
Butter
The base of the flavor. Garlic butter gives the beef a luxurious, savory coating. Use unsalted to better control seasoning.
Fresh Garlic
Use plenty! Garlic infuses the butter and slowly flavors the beef as it simmers. It softens into sweet, mellow bites.
Beef Broth
Just a splash helps create a flavorful cooking environment without drowning the meat. Keeps everything moist and tender.
Worcestershire Sauce
A secret umami booster that gives depth and enhances the beef’s natural flavor without overpowering it.
Italian Seasoning or Fresh Herbs
A blend of oregano, thyme, rosemary, and basil adds a savory herbal note. Fresh parsley at the end brightens everything up.
Salt and Black Pepper
Simple seasonings that bring out the full potential of the garlic and beef.
Step-by-Step Instructions
These garlic butter beef bites take just 10–15 minutes to prep and slow cook to perfection. Here’s how:
1. Prep the Beef
Trim 2½ to 3 lbs of beef chuck or sirloin and cut into 1½-inch cubes. Pat dry with paper towels and season with:
-
1½ tsp salt
-
1 tsp black pepper
-
1 tsp Italian seasoning
Optional: Sear the beef in batches in a hot skillet with 1 tablespoon olive oil for 2–3 minutes per side to add extra depth of flavor.
2. Make the Garlic Butter Mixture
In a small saucepan (or microwave), melt:
-
6 tablespoons unsalted butter
-
Stir in 6–8 cloves garlic, minced
-
Add 1 tablespoon Worcestershire sauce
-
Optional: pinch of red pepper flakes or smoked paprika for a kick
Let simmer for 1–2 minutes to soften the garlic and bloom the flavor.
3. Add Everything to the Slow Cooker
Place the beef cubes into a 6-quart slow cooker. Pour the garlic butter mixture over the top. Add:
-
¼ cup low-sodium beef broth
-
Optional: 1 sprig rosemary or thyme (remove before serving)
Stir to coat all the beef.
4. Slow Cook
Cover and cook on:
-
LOW for 6–8 hours (best for chuck roast)
-
HIGH for 3½–4 hours (works for sirloin)
Beef should be very tender but not shredded—bite-sized and juicy.
5. Serve
Give everything a stir and spoon the garlic butter over the beef bites. Garnish with freshly chopped parsley or serve with a lemon wedge for brightness.

Yes. Cool completely, transfer to a freezer-safe container, and freeze up to 3 months. Thaw in the fridge overnight and reheat gently.
