Ingredients You’ll Need
One of the best things about Crockpot Steak Bites is how just a handful of straightforward ingredients come together to create something truly special. Each component plays a part in building deep flavor, melt-in-your-mouth texture, and a mouthwatering aroma that will fill your home as they cook.
- Sirloin Steak (3 pounds, cut into bite-sized pieces): Tender, hearty, and perfect for soaking up all those incredible juices. Don’t be afraid to substitute with round steak, stew meat, or chuck roast if that’s what you have.
- Kosher Salt (2 teaspoons): Enhances the natural flavor of the beef and helps tenderize every bite.
- Black Pepper (1 teaspoon): Adds a hint of gentle heat and rounds out the flavors.
- Vegetable Oil (2 tablespoons): Essential for getting that beautiful sear on the steak bites to lock in flavor before slow cooking.
- Sweet Onion (1 small, thinly sliced): Brings a subtle sweetness that melts right into the sauce.
- Garlic (3 cloves, thinly sliced): Infuses each bite with rich, aromatic depth.
- Unsalted Beef Stock (1 cup): The foundation for a savory, luscious au jus. You can use unsalted beef broth as an alternative.
- Au Jus Gravy Mix (1 packet, 1 ounce): Shortcut to a concentrated burst of traditional flavor—no mess, no fuss.
- Unsalted Butter (4 tablespoons, thinly sliced): Melts into the sauce, lending creaminess and shine.
- Fresh Chopped Parsley (for garnish, optional): Adds a pop of color and herbal brightness; not essential, but delightful if you have it.
How to Make Crockpot Steak Bites
Step 1: Season the Steak
Start by tossing your bite-sized chunks of sirloin in a large bowl with kosher salt and black pepper. This little bit of prep brings out the meat’s natural flavor and sets the foundation for a truly tasty result.
Step 2: Sear the Steak Bites
Heat up a large skillet over medium-high heat, add half the vegetable oil, and work in batches to sear the steak pieces until they’re just browned on the outside. Searing adds fantastic depth to the steak bites, locking in juices and creating those irresistible caramelized flavors. Don’t overcrowd the pan—sear in batches and add more oil if needed.
Step 3: Fill the Crockpot with Flavor
Transfer your beautifully browned steak pieces directly into the slow cooker. Scatter the thinly sliced onion and garlic over the top, then give everything a gentle toss so those fragrant flavors mingle together.
Step 4: Add Liquid Gold
Pour in the unsalted beef stock, then sprinkle the contents with the au jus gravy mix. Top it off by layering thin slices of unsalted butter over everything for extra richness as it cooks.
Step 5: Slow Cook to Tender Perfection
Pop the lid on your crockpot and let the magic happen! Cook on high for 3 to 4 hours or on low for 6 to 8 hours, stirring every half hour or so if you can. When finished, the steak bites will be fork-tender and swimming in that insanely flavorful au jus.
How to Serve Crockpot Steak Bites

Garnishes
For a fresh and vibrant touch, a sprinkle of chopped parsley over your Crockpot Steak Bites does wonders to both flavor and presentation. If you’re feeling bold, a pinch of flaky sea salt or even some freshly cracked black pepper can add a bit of extra zing right before serving.
Side Dishes
These steak bites truly shine when spooned over a pillowy mound of mashed potatoes or egg noodles—both capture that luscious sauce beautifully. They also pair wonderfully with classic sides like buttered green beans, roasted carrots, or a crisp green salad to round out the meal.
Creative Ways to Present
Try piling the Crockpot Steak Bites onto toasted sub rolls for an irresistible steak sandwich, or serve them appetizer-style on small skewers at parties. They’re also delightful as a filling for baked potatoes or even over rice for a versatile twist. However you serve them, don’t forget a drizzle of extra au jus!
Make Ahead and Storage
Storing Leftovers
Leftover Crockpot Steak Bites keep fabulously well—simply place them in an airtight container and refrigerate for up to 3 days. The flavors deepen as they sit, so you may find them even tastier the next day!
Freezing
If you’d like to freeze leftovers, let the steak bites cool completely first. Store in freezer-safe containers or heavy-duty freezer bags, ensuring plenty of the au jus is included to keep the meat moist. Properly stored, they’ll keep beautifully in the freezer for up to 3 months.
Reheating
Reheating is a breeze—warm your Crockpot Steak Bites gently on the stovetop or in the microwave, adding a splash of beef stock or water if needed to loosen the sauce. Always reheat until piping hot and enjoy the convenience of a meal that still tastes homemade.
FAQs
Can I use a different cut of beef for Crockpot Steak Bites?
Absolutely! While sirloin is ideal for its tenderness, you can easily swap in round steak, stew meat, or chuck roast. Each will offer a slightly different texture and flavor, but all work wonderfully in this slow-cooked recipe.
Do I have to sear the steak bites first?
Searing is technically optional, but it gives a big boost of flavor and color to the final dish. If you’re pressed for time, you can skip it, but I highly recommend taking the extra few minutes for best results.
Is it possible to make Crockpot Steak Bites without the au jus mix?
You can! For a homemade alternative, combine 1 teaspoon each of garlic powder, onion powder, and dried parsley with a pinch of black pepper and a splash of Worcestershire sauce. The flavor will be slightly different but still delicious.
Can I make Crockpot Steak Bites ahead of time for a party?
Definitely! Prepare the recipe as directed, then reheat gently in the slow cooker on the “warm” setting when ready to serve. This makes entertaining a breeze, and you can even keep them warm for hours during a gathering.
How can I make this recipe gluten-free?
Just double-check your au jus gravy mix and beef stock to ensure they’re gluten-free varieties. Otherwise, the rest of the ingredients are naturally gluten-free, making this a perfect dish for those with dietary restrictions.
