French Onion Butter Bottom Round Roast: Slow Cooker

This is the kind of recipe that feels like a secret: just four ingredients, one slow cooker, and a roast that turns out so tender it practically shreds itself.

The combination of sweet Vidalia onions, rich beef consommé, and a whole stick of butter creates a silky, deeply savory sauce that coats every bite. It's the set-it-and-forget-it dinner that makes a weekday feel like Sunday.

Forget complicated braises and endless steps. This French Onion Butter Bottom Round Roast is the ultimate hands-off dinner. A bottom round roast is seasoned simply, layered with sliced Vidalia onions, beef consommé, and a stick of butter, then left to cook low and slow until it's fall-apart tender.

The result is a rich, oniony, buttery sauce that's perfect over mashed potatoes or crusty bread. It's comfort food at its easiest.

Ingredients

Why this recipe works

The magic of this recipe lies in the combination of low heat and time. Cooking the bottom round roast on LOW for 8 to 10 hours allows the collagen in the meat to break down into gelatin, turning a tough, lean cut into a fork-tender, succulent roast.

The gentle heat also coaxes the natural sugars from the Vidalia onions, making them sweet and silky without any extra caramelization step.

The butter serves a dual purpose: it enriches the sauce and helps create a velvety, emulsified jus as it melts into the consommé.

The consommé, which is more concentrated than regular broth, provides a deep beefy flavor that stands up to the richness of the butter. Together, these simple ingredients create a complex, comforting sauce that tastes like it simmered all day—because it did.

Notes and substitutions

Bottom round roast is a lean, budget-friendly cut that shines with slow cooking. If you can't find it, chuck roast or brisket are excellent substitutes. Vidalia onions are sweet and mild, but any sweet onion like Walla Walla or Maui will work. For a more assertive onion flavor, use yellow onions.

Beef consommé is a concentrated, clarified broth that gives the sauce a deep, rich flavor. Look for it in the soup aisle; if you only have beef broth, use it, but consider adding a splash of Worcestershire sauce or a pinch of beef bouillon to boost the flavor. Salted butter is preferred here—if using unsalted, add a pinch of salt to the pot.

• Vidalia onions: Sweet onions like Walla Walla or Maui, or yellow onions for a sharper flavor.
• beef consommé: Beef broth or stock, but consommé is richer and more concentrated.
• salted butter: Unsalted butter plus 1/4 teaspoon salt, or use a flavored butter like garlic-herb.
• beef bottom round roast: Chuck roast or brisket, which are also well-suited for slow braising.
