Ingredients

Why this recipe works

Cooking beef chuck low and slow breaks down the connective tissue, turning it melt-in-your-mouth tender. The slow cooker maintains a gentle, consistent temperature that transforms tough cuts into succulent bites.

Meanwhile, the carrots and potatoes absorb the buttery, herby juices, becoming flavorful and soft without turning mushy.

The garlic-herb butter and au jus mix create a rich, savory sauce that coats every bite. The butter adds richness and a silky mouthfeel, while the au jus provides deep umami. Layering the ingredients without stirring keeps the beef on the bottom, where it browns slightly and develops extra flavor as it cooks.

Notes and substitutions

Choose well-marbled beef chuck for the best results — the fat keeps the meat moist during long cooking. Baby carrots are convenient and hold their shape well. Red bliss potatoes are waxy and stay firm, but Yukon Golds work too. If using larger potatoes, cut them into 1-inch chunks for even cooking.

Garlic-herb butter (often called cowboy butter) is sold in sticks or tubs at many supermarkets. If unavailable, make your own by mixing softened butter with minced garlic, parsley, and a pinch of salt.

Au jus mix adds a savory, beefy flavor; use a low-sodium version if preferred. The mashed potatoes for serving are not included in the slow cooker — prepare them separately.
