Discover the ultimate comfort food with this slow cooker beef and mushrooms recipe. Tender beef and earthy mushrooms simmered in a rich, savory gravy.
Introduction
Honestly, there are days when nothing beats a rich, slow-simmered dinner that requires almost zero effort on my part. I usually turn to my slow cooker when I want the house to smell like an upscale steakhouse without actually spending hours chained to the stove. That’s exactly how this Slow Cooker Beef and Mushrooms recipe became a regular rotation in my kitchen. The first time I tossed these tender beef cubes and sliced mushrooms into the crockpot with a savory broth, I knew it was a keeper. As you can see in the photo, it cooks down into this glossy, deeply flavorful gravy that coats every single piece. It’s high-protein, incredibly cozy, and practically foolproof.
Ingredients
-
2.5 lbs beef chuck roast: Cut into 1.5-inch bite-sized cubes. Chuck roast is my go-to because it breaks down into melt-in-your-mouth perfection.
-
8 oz fresh mushrooms: Sliced (cremini or button mushrooms work wonderfully).
-
1 large yellow onion: Finely diced.
-
4 cloves garlic: Minced.
-
1.5 cups beef broth: Low-sodium lets us control the salt level.
-
1 packet (1 oz) brown gravy mix: Gives the sauce an instant depth and thickness.
-
1 packet (1 oz) dry onion soup mix: Packed with savory flavor that saves you from chopping extra herbs.
-
2 tablespoons Worcestershire sauce: For that classic tangy, umami boost.
-
2 tablespoons unsalted butter: Cut into small pieces to add a rich, velvety finish.
-
2 tablespoons cornstarch + 2 tablespoons cold water: Mixed into a slurry to thicken the gravy right at the end.
Step-by-Step Method
-
Layer the aromatics and mushrooms: Scatter the diced yellow onions, minced garlic, and sliced mushrooms evenly across the bottom of your slow cooker insert.
-
Add the beef: Place the cubed chuck roast right on top of the mushroom and onion layer.
-
Mix the savory liquid: In a medium bowl, whisk together the beef broth, brown gravy mix, dry onion soup mix, and Worcestershire sauce until the packets are fully dissolved.
-
Pour and dot with butter: Pour the liquid mixture evenly over the beef and mushrooms. Scatter the small cubes of butter right over the top.
-
Slow cook to perfection: Cover the slow cooker and cook on LOW for 7 to 8 hours or on HIGH for 4 to 5 hours, until the beef is fork-tender and completely yielding.
-
Thicken the gravy: About 30 minutes before serving, whisk your cornstarch and cold water into a smooth slurry, then stir it gently into the slow cooker. Cover and let it bubble on HIGH for the last 30 minutes until the gravy is thick and glossy.
Cooking Tips
-
Don’t cut the beef too small: I usually keep the cubes around 1.5 to 2 inches. If they’re cut too small, they tend to dry out or shred completely instead of staying as nice, meaty bite-sized chunks.
-
Sear if you have extra time: While skipping this step works great on busy days, you can quickly sear the beef cubes in a hot skillet for 2 minutes per side before tossing them in the slow cooker for an even deeper, caramelized crust.
-
Choose your mushrooms: Cremini mushrooms (baby bellas) give a slightly earthier, richer flavor than standard white button mushrooms, but both work brilliantly.
Serving Suggestions
This dish is all about the gravy, so you definitely want something that can soak it up. I usually serve these beef tips and mushrooms piled high over a massive bed of creamy garlic mashed potatoes or buttered egg noodles. Steamed broccoli or green beans make a great green side to balance out the richness of the meal.

Frequently Asked Questions
Can I use frozen beef for this recipe? Honestly, I wouldn’t recommend it. Putting frozen meat in a slow cooker can keep it in the “danger zone” temperature range for too long, plus it releases too much water and dilutes the gravy. Always thaw your beef completely first!
What cut of beef works best besides chuck roast? If you can’t find a good chuck roast, bottom round roast or pre-cut stew meat will also work. Just keep in mind that chuck roast has the best fat marbling for that melt-in-your-mouth texture.
Can I make this ahead of time? Yes, you can prep everything in the slow cooker insert the night before, cover it, and keep it in the fridge. In the morning, just pop the insert straight into the heating base and turn it on.
How do I store leftovers? Store any leftovers in an airtight container in the refrigerator for up to 3 to 4 days. The flavors actually meld together even more overnight, making it taste fantastic for lunch the next day.
Can I freeze these beef tips? You can freeze the cooked beef and mushroom mixture in a freezer-safe container for up to 2 months. Just note that starch-thickened gravies can sometimes separate slightly when thawed, so give it a good stir while reheating on the stove.
