French Onion Dip

Learn how to make French Onion Dip from scratch with caramelized onions, cream cheese, sour cream and/or mayo, and simple seasonings!


  • 1 Tablespoon olive oil
  • 2 Tablespoons Salted Butter
  • 2 large yellow Onions, about 2.5 cups finely diced
  • 2 teaspoons low sodium soy sauce
  • 1 teaspoon Garlic Salt
  • ½ teaspoon Onion Powder
  • ½ teaspoon pepper
  • ¼ teaspoon dried thyme
  • 1 cup Sour Cream
  • 4 oz. Cream Cheese, cut into cubes


  • Take out the cream cheese and let it soften while you caramelized the onions.
  • Add butter, olive oil, and onions to a 12-inch skillet over medium heat. Toss to combine and heat for 5 minutes, until softened.
  • Add soy sauce, garlic salt, onion powder, pepper, and thyme. Reduce heat to low.
  • Cover partially and cook for 20-25 minutes, until caramelized. Stir every few minutes. Remove from heat and let cool.
  • Combine the cream cheese with sour cream (and/or mayo). Add caramelized onions. If possible, refrigerate for at least 1 hour prior to serving.


  • This recipe makes 1 ¾ cups.
  • A combination of mayo and sour cream can be used.
Baked Version (with Cheese):
  • Once the onions are caramelized, remove from heat and add cream cheese and sour cream.
  • Add 3 Tbsp. grated Parmesan cheese along with 1 cup of shredded gruyere or mozzarella cheese.
  • Top with an additional 1 cup of cheese.
  • Bake in a cast iron skillet or oven-safe dish 375° for 15 minutes, uncovered.
  • You may choose to broil it at 450° for up to 5 minutes at the end for a brown top.
