Why You’ll Love This Recipe

I love how incredibly easy this is to prepare—just a few minutes of searing and chopping, then everything goes into the slow cooker. The beef becomes so tender, and the mushrooms soak up all the meaty flavor. It’s a comforting, low-effort dinner that tastes like I spent hours in the kitchen. Plus, it’s made with simple ingredients I usually already have on hand.

ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

2 pounds stew beef
8 ounces white mushrooms
⅓ cup white onion, chopped
6 tablespoons butter, sliced
3 cloves garlic, minced
¾ cup beef broth
1 teaspoon salt
1 teaspoon black pepper

directions

I start by searing the stew beef in a skillet over medium-high heat until it’s browned on all sides. This helps lock in flavor, but I don’t fully cook the meat here.
I transfer the browned beef to the slow cooker, then add the mushrooms, chopped onion, sliced butter, minced garlic, beef broth, salt, and pepper.
I give everything a gentle stir to combine, then cover and cook on LOW for 4 to 6 hours until the beef is tender.
If I want a thicker sauce, I mix in a cornstarch slurry near the end and let it cook for another 15 minutes until thickened.

Variations

I sometimes use sirloin tips instead of stew beef for a leaner cut.
For more flavor, I like to add Worcestershire sauce or a splash of soy sauce to the broth.
If I want extra richness, I use sliced baby bella mushrooms instead of white mushrooms.
For a spicy kick, I’ll add red pepper flakes or a dash of hot sauce.
I also like to throw in baby carrots or small potatoes to make it a one-pot meal.

storage/reheating

I store any leftovers in an airtight container in the refrigerator for up to 3 days. When I want to reheat, I use the microwave or warm it on the stove over low heat with a splash of broth to loosen the sauce.

For longer storage, I freeze the cooled beef and sauce in a freezer-safe container or bag for up to 3 months. To reheat, I thaw overnight in the fridge and then warm it on the stove or in the microwave.

FAQs

What type of beef is best for this recipe?

I usually use stew beef or chuck roast cut into bite-sized pieces. These cuts become incredibly tender in the slow cooker.

Do I have to sear the beef first?

While it’s not absolutely necessary, I like to sear the beef because it adds a deeper, richer flavor to the final dish.

Can I make this in the Instant Pot?

Yes, I can adapt this for the Instant Pot. I sear the beef using the sauté function, then pressure cook everything on high for about 20 minutes with a natural release.

How can I thicken the sauce?

If I want the sauce to be thicker, I make a cornstarch slurry with 1 tablespoon of cornstarch and 2 tablespoons of cold water, then stir it into the slow cooker 15 minutes before serving.

What should I serve with mushroom steak bites?

I usually serve this over mashed potatoes, egg noodles, or rice. It’s also great with roasted vegetables or crusty bread on the side.

Conclusion

Slow cooker mushroom steak bites are one of my favorite set-it-and-forget-it meals. The beef turns out incredibly tender, the mushrooms soak up all the savory flavor, and the buttery, garlicky sauce brings it all together. It’s a comforting, satisfying dinner that’s simple enough for weekdays but feels special enough for weekends.
