Slow Cooker Garlic Butter Steak Bites
There are days when I want steak for dinner, but I don’t necessarily want to stand over a hot skillet cooking piece after piece. That’s when these slow cooker steak bites come in handy.
I usually cut the beef into generous bite-sized pieces, give them a quick sear for that gorgeous browned crust, and then let the slow cooker take over. The meat cooks slowly with garlic, onions, butter, and savory seasonings until everything is tender and swimming in a rich, flavorful sauce.
Honestly, the smell alone is enough to make everyone wander into the kitchen asking when dinner is ready.
And while these steak bites look fancy enough for a weekend meal, they’re actually incredibly simple. Serve them with mashed potatoes, rice, noodles, or even crusty bread for soaking up all that buttery sauce.
Ingredients
For the Steak Bites
- 2 pounds beef chuck roast or sirloin steak, cut into 1½-inch cubes
- 1½ teaspoons salt
- 1 teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon smoked paprika
- ½ teaspoon onion powder
- 2 tablespoons all-purpose flour, optional
- 2 tablespoons olive oil, for searing
For the Garlic Butter Sauce
- 4 tablespoons unsalted butter
- 1 medium yellow onion, diced
- 5–6 cloves garlic, minced
- 1 cup beef broth
- 1 tablespoon Worcestershire sauce
- 1 teaspoon dried thyme
- ½ teaspoon dried rosemary
- ½ teaspoon smoked paprika
- 1 tablespoon chopped fresh parsley, plus more for garnish
Optional
- ½ teaspoon red pepper flakes for a little heat
- 1 tablespoon cornstarch + 2 tablespoons cold water for a thicker sauce
How to Make Slow Cooker Steak Bites
1. Cut and season the beef
Start by cutting your beef into roughly 1½-inch chunks.
Try to keep the pieces relatively similar in size so they cook evenly.
Pat the beef dry with paper towels. This little step makes a difference when you’re trying to get a nice brown crust.
Season the steak pieces with salt, pepper, garlic powder, smoked paprika, and onion powder.
If you like a slightly thicker sauce, toss the beef lightly with flour.
2. Sear the steak bites
Heat the olive oil in a large skillet over medium-high heat.
Once the skillet is hot, add the beef in batches. Don’t crowd the pan—this is important because crowded beef tends to steam instead of brown.
Sear the pieces for about 1–2 minutes per side, just until they’re nicely browned.
They don’t need to be cooked through at this point.
I know it’s tempting to skip this step when you’re making a slow cooker recipe, but honestly, I wouldn’t. That browned crust adds so much flavor to the finished dish.
Transfer the seared steak bites to your slow cooker.
3. Sauté the onions and garlic
Reduce the heat to medium and add the butter to the same skillet.
Add the diced onions and cook for about 3–4 minutes, until they begin to soften.
Add the minced garlic and cook for another 30–60 seconds.
Be careful not to burn the garlic.
Those browned bits stuck to the bottom of the skillet? Scrape them up as the butter melts. That’s where a lot of the good stuff is hiding.
4. Make the sauce
Pour the beef broth into the skillet and stir well, scraping up any remaining browned bits.
Add the Worcestershire sauce, thyme, rosemary, and smoked paprika.
Let the mixture simmer for about 1–2 minutes.
5. Add everything to the slow cooker
Pour the buttery onion mixture over the steak bites.
Make sure the beef is spread out in the slow cooker and coated with the sauce.
Cover with the lid.
6. Slow cook until tender
Cook on:
- LOW for 5–7 hours, or
- HIGH for 2½–3½ hours
The exact cooking time depends on the cut of beef and the size of your pieces.
I usually choose LOW when I have the time. The slow cooking gives tougher cuts like chuck plenty of time to become tender.
7. Finish the sauce
When the steak bites are tender, taste the sauce and adjust the salt and pepper.
If you prefer a thicker sauce, mix 1 tablespoon cornstarch with 2 tablespoons cold water.
Stir the slurry into the hot sauce and cook for another 10–15 minutes with the slow cooker on HIGH, until thickened.
Finish with fresh parsley.
Cooking Tips for the Best Slow Cooker Steak Bites
Choose the right beef
For incredibly tender slow cooker steak bites, chuck roast is a great choice because the connective tissue breaks down during slow cooking.
Sirloin can also work, especially if you prefer a leaner result, but be careful not to overcook it.
Sear the beef first
This is probably my biggest tip. A quick sear creates those deep, caramelized flavors that you simply don’t get from putting raw beef straight into the crockpot.
Don’t overcrowd the skillet
Work in batches if necessary. Give each piece enough room to touch the hot pan.
Cut the beef evenly
Try to keep your steak pieces around the same size. Smaller pieces will cook faster than large chunks.
Don’t add too much liquid
The slow cooker doesn’t allow much evaporation, so you don’t need to completely submerge the beef. Too much liquid can leave you with a thin, diluted sauce.
Taste before serving
Beef broth and Worcestershire sauce can vary quite a bit in saltiness. I always taste the finished sauce before adding more salt.
What to Serve With Steak Bites
These slow cooker steak bites are wonderfully versatile.
I usually serve them with creamy mashed potatoes because that buttery sauce over potatoes is hard to beat.
Other great options include:
- White rice
- Garlic mashed potatoes
- Buttered egg noodles
- Roasted potatoes
- Cauliflower mash
- Steamed green beans
- Roasted broccoli
- Glazed carrots
- Corn on the cob
- Crusty French bread
- Dinner rolls
For a simple family dinner, I’d go with mashed potatoes and green beans. It’s easy, filling, and the leftovers are just as good the next day.
How to Store Leftover Steak Bites
Let the steak bites cool slightly before transferring them to an airtight container.
Store them in the refrigerator for 3–4 days.
When reheating, use the microwave in short intervals or warm them gently in a saucepan over low heat. Add a splash of beef broth if the sauce has become too thick.
You can also freeze the steak bites and sauce for approximately 2–3 months in a freezer-safe container.
Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions
1. What cut of beef is best for slow cooker steak bites?
I like chuck roast for slow cooking because it becomes incredibly tender and flavorful. Sirloin is another good option if you want something leaner, although it generally needs less cooking time.
2. Can I make steak bites without searing the meat?
Yes, you can. Simply season the beef and add it directly to the slow cooker. However, I highly recommend searing it first. That extra few minutes gives the finished dish a much deeper, richer flavor.
3. Why are my steak bites still tough?
If you’re using chuck or another slow-cooking cut, tough beef usually means it needs more time, rather than less. Continue cooking until the connective tissue breaks down and the beef becomes fork-tender.
4. Can I add mushrooms?
Absolutely! Mushrooms are delicious with steak and garlic butter. Add sliced mushrooms during the final few hours of cooking for a firmer texture, or add them earlier if you prefer them very soft.
5. Can I make these steak bites spicy?
Definitely. Add ½ teaspoon of red pepper flakes, a pinch of cayenne, or a little hot sauce to the gravy. I usually start with a small amount—you can always add more at the end.
Final Thoughts
These slow cooker steak bites with garlic butter are one of those recipes that feel much more complicated than they actually are.
You get beautifully browned pieces of beef, tender onions, plenty of garlic, and a buttery, savory sauce—all with very little hands-on work.
I usually make a big batch when I know we’ll want leftovers because, honestly, the steak bites might be even better the next day. Spoon them over mashed potatoes, add some green vegetables on the side, and you’ve got the kind of comforting dinner that everyone tends to come back for seconds of.
