Ingredients

Why this recipe works

The slow cooker transforms beef tenderloin tips into meltingly tender bites. The low, moist heat breaks down connective tissue without drying out the lean cut, while the butter and au jus create a rich, flavorful sauce that coats every piece.

Cooking on low for several hours allows the flavors to meld and the beef to absorb the garlic and herbs.

The potatoes cook right alongside the beef, soaking up the seasoned butter as they soften. Because they are halved, they cook at the same rate as the beef, becoming creamy and tender without turning to mush.

The hands-off method means you can walk away and come back to a fully cooked, satisfying dinner.

Notes and substitutions

Beef tenderloin tips are the star of this dish, but you can substitute sirloin steak cut into cubes if needed. Look for pre-cut tips at the butcher counter for convenience.

Baby Yukon Gold potatoes hold their shape well and have a buttery flavor that complements the sauce; red potatoes or fingerlings work too.

Garlic-herb cowboy butter is a flavored butter sold in sticks or tubs. If you cannot find it, mix 1/2 cup softened unsalted butter with 1 tablespoon minced garlic and 1 teaspoon dried parsley or chives. The dry au jus mix adds depth and salt; use a low-sodium version if you prefer.
