Air Fryer French Onion Dip Recipe Tips

  • Use Quality Beef Broth: Choose a high-quality beef broth or stock for the best flavor. 
  • Mix Cheeses Thoroughly: Ensure your cream cheese is softened before mixing it with sour cream and mayonnaise. 

  • Seasoning is Key: Don’t skimp on the garlic salt and thyme. 

  • Combine Ingredients Carefully: Once the onions are caramelized and the cheese mixture is ready, combine all ingredients gently but thoroughly.  

  • Use the Right Baking Dish: Transfer the mixture to an oven-safe baking dish that fits in your air fryer. A smaller, deeper dish will keep the dip warm and gooey longer, whereas a wider, shallower dish will create more crispy edges.

  • Serve Immediately: French onion dip is best served hot. Have your dipping options ready—such as chips, crackers, or fresh vegetables—so you can enjoy the dip at its peak flavor and texture.

Serve it with chips, crackers, or fresh vegetables for a variety of delicious dipping options.
