Slow Cooker Cowboy Butter Beef Bites Step-by-step instructions

Before you start

Before starting, cut the beef chuck into 1-inch cubes if not already done. Quarter the red potatoes — leave baby potatoes whole if they are small. Measure the butter and au jus mix.

Have a 6-quart slow cooker ready. No need to brown the beef or pre-cook anything; this recipe is truly dump-and-go. If you plan to serve over mashed potatoes, prepare them just before serving or keep warm.

Instructions

Layer and Season

1. 1Layer the Ingredients
   Place the cubed beef chuck in the bottom of a 6-quart slow cooker. Scatter the baby carrots and quartered red potatoes evenly over the beef. No need to stir — the layers will meld as they cook.
   Look for The slow cooker should be about half full with beef, carrots, and potatoes.
   Tip Cut potatoes into similar-sized pieces so they cook evenly.
2. 2Add Butter and Au Jus
   Dollop the softened garlic-herb butter over the top of the meat and vegetables. Sprinkle the au jus mix evenly over everything.
   Look for The butter and seasoning are spread over the surface.
   Tip If the butter is too firm, cut it into small pieces for even distribution.

At the end of this phase, the slow cooker contains a neat layer of raw beef cubes, topped with orange baby carrots and red potato quarters. The butter and au jus mix are sprinkled over the top, creating a speckled, buttery surface. The raw ingredients look fresh and vibrant, and the butter is just beginning to soften. Everything is ready for the long, slow cook.

Slow Cook to Tender

3. 3Cover and Cook Low and Slow
   Cover the slow cooker and cook on LOW for 6 to 8 hours, or on HIGH for 3 to 4 hours, until the beef is fork-tender and the potatoes are easily pierced. Stir gently once halfway through if possible. Let it rest for 3 minutes before slicing.
   Look for The aroma of garlic and herbs fills the kitchen as it cooks.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Resist lifting the lid often — it releases heat and extends cooking time.
4. 4Check for Tenderness
   Test the beef with a fork — it should shred easily or cut with no resistance. The carrots should be tender and the potatoes soft. If not done, continue cooking for another 30 minutes. Let it rest for 3 minutes before slicing.
   Look for The beef pulls apart with a fork and the potatoes are creamy inside.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip If the sauce seems thin, remove the lid and cook on HIGH for 15-20 minutes to reduce.

After several hours, the slow cooker is bubbling gently. The beef has turned a rich brown, the carrots have deepened in color, and the potatoes are tender.

The sauce is golden and fragrant, with visible herbs and a glossy sheen. The aroma of garlic and butter fills the room. The beef should be fork-tender and the vegetables easily pierced. If not, continue cooking and check again.

Rest and Serve

5. 5Rest the Meat
   Turn off the slow cooker and let the beef rest for at least 3 minutes before serving. This allows the juices to redistribute, keeping the meat moist.
   Look for The bubbling subsides slightly as it rests.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Resting is quick but essential for the most tender bites.
6. 6Serve Over Mashed Potatoes
   Spoon the beef, carrots, potatoes, and buttery au jus over creamy mashed potatoes. Serve hot, with extra sauce spooned on top.
   Look for The golden sauce glistens over the tender beef and vegetables.
   Tip Use a slotted spoon for serving if you prefer less sauce, or ladle generously.

The slow cooker is off, and the sauce has stopped bubbling. The beef is resting in the hot liquid, releasing its juices. The carrots are glazed, the potatoes are creamy, and the sauce is thick enough to coat a spoon. When you lift a spoonful, it steams and smells deeply savory. The dish is ready to be served over mashed potatoes, with extra sauce ladled on top.

Common mistakes

One common mistake is lifting the lid too often, which releases heat and extends cooking time. Another is cutting the potatoes too small, causing them to turn mushy. Avoid overloading the slow cooker — leave at least an inch of space at the top for even cooking.

Also, don’t skip the resting time after cooking; it allows the meat to reabsorb juices. Finally, if you prefer a thicker sauce, use a cornstarch slurry, but the video’s version is intentionally brothy.

How to tell it’s done

The dish is done when the beef is fork-tender — it should shred or cut easily with no resistance. The carrots should be tender but not falling apart, and the potatoes should be soft and easily pierced with a fork.

The internal temperature of the beef should reach at least 145°F (63°C) for food safety, but because it cooks low and slow, it will be far more tender. If the sauce is too thin, remove the lid and cook on HIGH for 15-20 minutes to reduce.

• Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
