Ingredients

Why this recipe works

The slow cooker is the hero here. Low, even heat transforms tough sirloin tips into tender, juicy morsels over several hours. The beef consommé provides deep umami flavor while the onions soften and sweeten as they cook.

This method requires zero babysitting — just layer everything in the pot and walk away. The result is a rich, complex sauce that tastes like it simmered for hours, because it did.

Cream cheese and Gruyère are stirred in at the end, creating a silky, creamy texture that clings to the beef. The cream cheese adds tang and body, while the Gruyère brings nuttiness and a beautiful melt.

Because the cheese is added after cooking, it doesn't curdle or separate. The sauce becomes a luxurious gravy that elevates the humble sirloin tips into a restaurant-worthy dish.

Notes and substitutions

Choose sirloin tips that are well-marbled for the most flavor and tenderness. If you can't find sirloin tips, you can use chuck roast cut into chunks — it will also become tender with long cooking. Vidalia onions are sweet and mild, but any sweet onion works. For a sharper flavor, use yellow onions.

Gruyère is the classic choice for French onion soup, but Swiss cheese or Emmentaler are good substitutes. Make sure to shred it yourself from a block for the best melt. The brioche is optional but highly recommended — it soaks up the sauce beautifully. For a gluten-free option, serve over mashed potatoes or rice instead.

• Vidalia onions: Sweet onions like Walla Walla or Maui, or yellow onions for a sharper flavor.
• Gruyère cheese: Swiss cheese or Emmentaler for a similar nutty, melty texture.
• Beef consommé: Beef broth with a pinch of onion powder and a splash of soy sauce for depth.
• Brioche bread: Crusty baguette slices or sourdough, toasted for serving.
