5-Ingredient Crockpot Steak Bites are the kind of recipe that makes weeknight cooking feel effortless. I still remember the first time I tossed everything into my slow cooker on a busy Tuesday morning. By dinnertime, my kitchen smelled like Sunday supper, and those tender bites were swimming in the richest, most savory gravy you can imagine.
Growing up in the Midwest, I learned that the best meals don’t need fancy ingredients or complicated steps. My grandmother used to say that good cooking is about letting simple ingredients do their magic, and that’s exactly what happens with these steak bites. The slow cooker transforms affordable sirloin into fork-tender pieces that practically melt in your mouth, while the au jus and onion soup mix create a gravy so good you’ll want to soak it up with every last bit of bread on your plate. Let’s get that crockpot working.

Understanding Your Ingredients
Top sirloin steak gives you the best balance of flavor and tenderness for slow cooking. I always choose a well-marbled cut because that fat breaks down during cooking and adds so much richness to the gravy.
Au jus gravy mix brings that deep, beefy flavor that makes these steak bites taste like they’ve been simmering all day. In my kitchen, I prefer the packets without MSG if you can find them.
Onion soup mix adds layers of savory flavor and helps thicken the gravy naturally as it cooks. This is one of those secret ingredients that does so much heavy lifting in such a simple recipe.
Butter creates richness and helps the gravy develop that silky, restaurant-quality finish. I’ve found that real butter makes all the difference here, not margarine.
Beef broth forms the base of your gravy and keeps everything moist during the long cooking time. Low-sodium broth gives you better control over the final seasoning.
Betty’s Tested Technique
Step 1. I’ve learned that taking a few minutes to trim any excess fat and gristle from your steak makes a big difference in the final texture. Cut the meat into even 1-inch cubes so everything cooks at the same rate.
Step 2. Place your steak cubes in a single layer at the bottom of your slow cooker. If you’re making a larger batch, it’s okay to have a bit of overlap, but try to keep it mostly even.
Step 3. Sprinkle both the au jus mix and onion soup mix evenly over the meat. I like to shake the crockpot gently to make sure the seasoning gets into all the nooks and crannies.
Step 4. Dot the butter pats across the top of the steak. As they melt, they’ll create pockets of richness throughout your dish.
Step 5. Pour the beef broth over everything, making sure to distribute it evenly. The liquid should come about halfway up the meat.
Step 6. Cover and cook on LOW for 4 to 6 hours or HIGH for 3 to 4 hours. I’ve found that low and slow gives you the most tender results. You’ll know it’s done when the meat is fork-tender and the gravy has thickened.
Step 7. Give everything a gentle stir, garnish with fresh chopped parsley if you like, and serve these beauties over mashed potatoes, rice, or noodles.
Keeping This Recipe Fresh
I typically store leftover steak bites in an airtight container in the refrigerator for up to 4 days. The gravy thickens as it sits, which actually makes the leftovers even better the next day. For the best texture when reheating, I warm them gently on the stovetop over low heat, adding a splash of beef broth if the gravy has gotten too thick. You can also microwave individual portions, though the stovetop method keeps the meat more tender.
For longer storage, these freeze beautifully for up to 3 months. I like to portion them into freezer-safe containers or bags so I can thaw just what I need. Thaw overnight in the refrigerator before reheating.

Building the Perfect Plate
These rich, savory steak bites pair beautifully with sides that can soak up all that incredible gravy. I love serving them over creamy mashed potatoes or buttered egg noodles. For a lighter option, steamed rice works wonderfully too.
- Garlic Parmesan Mashed Potatoes for a rich, creamy base
- Buttered Egg Noodles to catch every drop of gravy
- Steamed Rice for a lighter starch option
- Roasted Vegetables to add color and freshness
- Crusty Bread for soaking up that delicious gravy
- Simple Green Salad to balance the richness
FAQs
I recommend sticking with sirloin for the best results, but chuck roast or flat iron steak can work in a pinch. Just be aware that fattier cuts may need longer cooking times to become tender.
No, that’s the beauty of this recipe. The slow cooking and seasoning packets do all the work for you, so you can skip the browning step entirely.
You can, but I’ve found that cooking on LOW for 4 to 6 hours gives you the most tender, melt-in-your-mouth results. HIGH works in a pinch for 3 to 4 hours.
