Slow-Cooker Gruyère French Onion Tenderloin Tips

This slow-cooker recipe turns beef tenderloin tips, sweet Vidalia onions, and a duo of creamy cheeses into a rich, savory dinner that tastes like it simmered all day—because it did. You simply dump the ingredients into the crockpot, set it, and forget it.

When you return, the beef is fork-tender, the onions are caramelized, and the sauce is bubbling and luxurious. Serve it over toasted garlic brioche for a meal that feels fancy but couldn't be easier.

This recipe is a set-it-and-forget-it dinner that delivers restaurant-quality flavor with minimal effort. Beef tenderloin tips are the star—they're naturally tender and become even more so after a long, slow simmer in beef consommé.

The addition of sliced Vidalia onions adds a gentle sweetness that deepens as they cook down into silky ribbons. Cream cheese and Gruyère melt into a rich, velvety sauce that clings to every bite. It's the kind of meal that fills the kitchen with an irresistible aroma and makes everyone eager to sit down.

Ingredients

Why this recipe works

Slow cooking is the secret to this dish's melt-in-your-mouth texture. Beef tenderloin tips are already a tender cut, but the low, moist heat of the slow cooker breaks down any connective tissue and lets the meat soak up the savory consommé.

The result is beef that's fork-tender and infused with flavor, without any risk of drying out.

The combination of cream cheese and Gruyère creates a sauce that's both creamy and deeply savory. Cream cheese adds richness and body, while Gruyère brings a nutty, slightly sweet note that pairs perfectly with the caramelized onions.

As the cheeses melt together, they emulsify into a silky sauce that coats the beef and onions beautifully.

Notes and substitutions

Beef tenderloin tips are the ideal cut here because they're lean yet tender. If you can't find them, sirloin steak cut into 1-inch cubes works well—just add about 30 minutes to the cooking time. Vidalia onions are sweet and mild; if they're not in season, use yellow onions or another sweet variety like Walla Walla.

Beef consommé is a rich, clarified broth that adds deep flavor. If you don't have it, use beef broth and add a pinch of onion powder for extra depth. The cream cheese must be softened to room temperature so it melts smoothly; cold cream cheese can leave lumps. Gruyère can be replaced with Swiss or Emmental for a similar taste.
