Ingredients You’ll Need
- 3 lb sirloin steak: Tender cuts like sirloin are ideal; they hold up beautifully in slow cooking. You can substitute with ribeye if you prefer marbled beef.
- 2 tsp coarse salt: This enhances the beef’s natural flavor. Use kosher salt as it distributes evenly without overwhelming the palate.
- 1 tsp ground black pepper: Freshly ground offers a brighter taste, which complements the richness of the butter.
- 1 tbsp vegetable oil: For searing, it provides a high smoke point, ideal for locking in flavors when browning the beef.
- 1 small sweet onion: Adds a subtle sweetness that balances the rich garlic and beef; yellow or red onions work well as alternatives.
- 3 garlic cloves: Thinly sliced, they infuse the entire dish with aromatic depth. Garlic powder can be used in a pinch but lacks the same impact.
- 1 cup unsalted beef stock: Offers moisture and enhances the flavor. You can use low-sodium if you prefer to control salt levels.
- 1 oz au jus mix: This ingredient thickens the sauce and adds umami richness, but a homemade blend of beef broth with cornstarch can work too.
- 4 tbsp unsalted butter: Adds a rich, velvety finish to the sauce. Try flavored butters for an interesting twist.
How to Make Crock Pot Garlic Butter Steak Bites
Season the Steak: Start by placing 3 pounds of sirloin steak cut into 1-inch cubes into a large bowl. Sprinkle in 2 teaspoons of kosher salt and 1 teaspoon of freshly ground black pepper. Toss everything together until each piece of steak is evenly coated—this step is crucial for building that savory flavor foundation!
Sear for Flavor: Heat a large skillet over medium-high heat and add 1 tablespoon of vegetable oil. It’s hot enough when shimmering. Carefully add the seasoned steak cubes in batches; don’t overcrowd the skillet. Brown each batch for a couple of minutes until the edges are golden. This step enhances flavor, giving the steak a beautiful crust without cooking it through.
Combine in Slow Cooker: Once all the steak is seared, transfer it to a 6-quart slow cooker. Add the sliced sweet onion and the garlic. Give everything a gentle stir to distribute the ingredients evenly—it’s pulling together beautifully already!
Add Stock and Finishing Touches: Pour 1 cup of unsalted beef stock over the beef mixture. Then, sprinkle an ounce of au jus mix across the top. Finally, lay 4 tablespoons of unsalted butter, cut into pats, over the surface. This is where the magic truly happens!
Cook Low and Slow: Cover the slow cooker and set it to high for 3-4 hours or on low for 6-8 hours. If possible, stir once an hour. This helps the flavors meld even more. You’re looking for fork-tender steak by the time cooking is complete—not falling apart, just perfectly cooked.
Serve & Enjoy: Once done, ladle out the succulent steak bites and sauce over your choice of mashed potatoes, egg noodles, or perfectly fluffy rice. The savory sauce soaked into every bite will leave everyone wanting more!

Storing & Reheating
To store your Crock Pot Garlic Butter Steak Bites, allow them to cool before transferring to an airtight container. They’ll stay fresh in the refrigerator for about 3-4 days. For longer storage, you can freeze the leftovers for up to 3 months. Just be sure to store them in a freezer-safe container. When you’re ready to indulge again, simply reheat in the microwave for 2-3 minutes or on the stovetop until warmed through. The flavors may intensify, but you can always add a splash of beef stock to refresh the sauce’s consistency.
Chef’s Helpful Tips
- Avoid crowding the pan when searing the steak; doing so will steam rather than brown, leading to a less flavorful outcome.
- Be sure to allow your steak to come to room temperature before cooking for even better results.
- If you have time, consider making the steak bites a day in advance. The flavors will deepen overnight, making them even tastier.
- A splash of Worcestershire sauce can amp up the rich flavor if you desire a little more complexity.
- For a bit of heat, add red pepper flakes or a dash of hot sauce when cooking!
As you wrap up this delightful culinary adventure, don’t forget that the best meals often come from experimenting! So feel free to play with ingredients and flavors. Gather your loved ones, set the table, and let the comforting aroma of Crock Pot Garlic Butter Steak Bites fill your home. Enjoy!
