Ingredients

Why this recipe works

Cooking beef chuck low and slow breaks down the connective tissue in the meat, turning tough cubes into melt-in-your-mouth bites.

The slow cooker provides gentle, even heat that allows the collagen to convert to gelatin, creating a silky, rich texture. The beef absorbs the garlic-herb butter and au jus as it simmers, so every bite is deeply flavorful.

The broccoli and mushrooms cook just enough to become tender without turning mushy. The butter and au jus create a luscious sauce that clings to the vegetables and beef. Because everything cooks together, the flavors meld and develop over time, resulting in a cohesive, comforting dish that tastes like it simmered all day—because it did.

Notes and substitutions

Beef chuck stew meat is ideal for slow cooking because it has enough marbling to stay moist and tender. Look for pre-cut stew meat or cut your own from a chuck roast. Broccoli should be cut into similar-sized florets so they cook evenly. Baby bella mushrooms add an earthy depth that complements the beef and butter.

Garlic-herb cowboy butter is the star of this dish; it's a compound butter made with garlic, herbs, and spices.

You can find it in the dairy section of many grocery stores, or make your own by mixing softened butter with minced garlic, parsley, chives, and a pinch of cayenne. Au jus gravy mix provides the savory, beefy base for the sauce—use a good-quality packet for the best flavor.
