Ingredients
1. Sour Cream
Sour cream provides the creamy, tangy base for the dip. Use full-fat sour cream for the richest texture, although reduced-fat varieties can also work.
2. Onion Soup Mix
A packet of dry onion soup mix provides the concentrated onion flavor and seasoning. It makes this recipe especially convenient because you don’t need to chop or cook onions.
3. Mayonnaise
Mayonnaise adds richness and gives the dip a smooth, creamy consistency. It also balances the tanginess of the sour cream.
How to Make 3-Ingredient Onion Overton Dip
Step 1: Combine the Ingredients
Add the sour cream, mayonnaise, and dry onion soup mix to a medium bowl.
Step 2: Stir Until Smooth
Mix everything together thoroughly until the soup mix is evenly distributed throughout the sour cream and mayonnaise.
Make sure to scrape around the bottom and sides of the bowl so there are no pockets of dry seasoning.
Step 3: Chill
Cover the bowl and refrigerate the dip for at least 30 minutes.
For the best flavor, let it chill for 1 to 2 hours. This gives the onion seasoning time to blend into the creamy base.
Step 4: Serve
Give the dip another quick stir before serving. Transfer it to a serving bowl and surround it with chips, crackers, or fresh vegetables.
Tips for the Best Onion Dip
Let It Chill
Although you can eat the dip immediately, chilling it allows the onion flavor to develop and become more balanced.
Mix Thoroughly
The dry onion soup mix can settle at the bottom, so stir well to distribute the seasoning evenly.
Adjust the Texture
If you prefer a thicker dip, use slightly more sour cream. For a richer, creamier dip, increase the mayonnaise slightly.
Make It Ahead
This is an excellent make-ahead appetizer. Preparing it several hours before serving gives the flavors plenty of time to blend.
Easy Variations
The basic three-ingredient version is delicious on its own, but you can customize it when you want something different.
Add Fresh Onion
For extra onion flavor, finely chop a small amount of sweet or green onion and stir it into the finished dip.
Add Chives
Freshly chopped chives provide a mild onion flavor and a fresh finish.
Make It Extra Creamy
Add a spoonful of softened cream cheese for a thicker, richer dip.
Add Herbs
Fresh parsley, dill, or chives can add a little freshness to the creamy dip.
Add Heat
For a spicy version, add a pinch of cayenne pepper or a few dashes of hot sauce.
What to Serve With Onion Dip
This dip pairs with almost any crunchy snack.
Try serving it with:
- Potato chips
- Tortilla chips
- Pretzels
- Crackers
- Pita chips
- Carrot sticks
- Celery sticks
- Cucumber slices
- Bell pepper strips
- Broccoli and cauliflower florets
For a party, arrange the dip in the center of a large platter and surround it with a variety of dipping options.
Can I Make This Dip Ahead of Time?
Absolutely. In fact, making it ahead is recommended.
Prepare the dip several hours before serving, cover it tightly, and refrigerate. The onion seasoning will have more time to blend with the sour cream and mayonnaise, resulting in a more flavorful dip.
How to Store Leftovers
Store leftover onion dip in an airtight container in the refrigerator.
For the best quality, enjoy it within 3 to 4 days. Stir well before serving again.
Do not leave the dip at room temperature for extended periods. If you’re serving it at a party, keep it chilled and replenish the serving bowl as needed.
Frequently Asked Questions
Can I use Greek yogurt instead of sour cream?
Yes. Plain Greek yogurt can replace some or all of the sour cream. The finished dip will have a slightly tangier flavor and thicker texture.
Can I use only sour cream?
You can replace the mayonnaise with additional sour cream, although the dip will have a lighter, tangier flavor.
How long should the dip chill?
At least 30 minutes is recommended, but 1 to 2 hours gives the onion seasoning more time to blend into the creamy base.
Can I make this the night before?
Yes. This dip is ideal for preparing the night before. Keep it covered and refrigerated until you’re ready to serve.
Is this dip good for parties?
Yes. Its simple preparation makes it especially convenient when you’re preparing several appetizers at once.
