Ingredients List
· 1 cup sour cream (full-fat recommended)

· Fresh chives or parsley, chopped

Step-by-Step Instructions
Step 1: Combine Ingredients
In a medium bowl, combine the sour cream, mayonnaise, and dry onion soup mix.
Step 2: Stir Until Smooth
Stir vigorously with a spatula or whisk until the soup mix is fully incorporated and the dip is smooth and uniform in color. (The dip will be thick and creamy.)
Step 3: Chill
Cover and refrigerate for at least 1 hour before serving. Chilling allows the flavors to meld and the dried onions to soften slightly. For the best flavor, chill for 2-4 hours or overnight.
Step 4: Garnish and Serve
Give the dip a final stir. Transfer to a serving bowl. Garnish with fresh chives or a sprinkle of paprika. Serve cold with chips, crackers, or vegetables.
Cooking Tips and Pro Tips for Best Results
· Use full-fat sour cream and mayonnaise: Low-fat or fat-free versions contain more water and stabilizers, which can result in a thinner, less creamy dip. Full-fat creates a rich, stable dip that holds its texture.
· Do not use Miracle Whip: Miracle Whip is sweeter and has a different flavor profile. Use real mayonnaise (Hellmann’s, Duke’s, or Kewpie).
· Let the dip rest: The dried onions need time to rehydrate and soften. Do not skip the chilling step.
· Make it ahead: This dip tastes even better after a day in the refrigerator. Make it 24 hours in advance.
· For a thinner dip: Add 1-2 tablespoons of milk or buttermilk and whisk until you reach your desired consistency.
· For a chunkier dip: Some brands of onion soup mix have larger onion flakes. If you prefer a smoother dip, pulse the dry soup mix in a food processor for a few seconds before adding.
Variations and Substitutions
· Greek Yogurt French Onion Dip: Substitute the sour cream with plain Greek yogurt. The dip will be tangier and higher in protein.
· Light French Onion Dip: Use low-fat sour cream and light mayonnaise. The dip will be thinner; add 1 tablespoon of cornstarch to thicken if needed.
· Caramelized Onion Dip: Sauté 1 large diced onion in 1 tablespoon of butter over medium-low heat for 15-20 minutes until deeply caramelized. Let cool, then stir into the sour cream and mayonnaise mixture (omit the soup mix or use half).
· Vegan French Onion Dip: Use vegan sour cream and vegan mayonnaise. Use a vegan onion soup mix (or make your own). Chill as directed.
· Spicy French Onion Dip: Add ½ teaspoon of cayenne pepper or 1 teaspoon of sriracha. Stir in 1 diced jalapeño.
· Herbed French Onion Dip: Add 1 tablespoon of fresh chopped chives and 1 tablespoon of fresh parsley.

2. Can I use low-fat or fat-free sour cream and mayonnaise?
You can, but the dip will be thinner and less creamy. Full-fat versions are strongly recommended for the best texture and flavor.
3. What is the best brand of onion soup mix?
Lipton Recipe Secrets onion soup mix is the classic choice. Store brands work well too. For a more intense onion flavor, look for a brand with visible dried onion flakes.
4. How long does this dip last in the refrigerator?
Up to 5 days in an airtight container. The dip may thicken as it sits; stir before serving.
5. Can I make this dip without mayonnaise?

6. Is this dip gluten-free?
Most dry onion soup mixes contain gluten (in the form of hydrolyzed wheat protein or maltodextrin). Look for a gluten-free onion soup mix or make your own (see below).
