Why Onion Dip Is a Must-Have Appetizer
Onion dip has been a crowd favorite since the 1950s—and it hasn’t lost its charm. But instead of using processed onion soup packets, we’re taking it back to basics with fresh caramelized onions, herbs, and Greek yogurt or sour cream.
It’s a great make-ahead option and pairs beautifully with chips, crackers, or veggie sticks. With the Thermomix, you can skip the stovetop stirring and go straight to smooth, bold flavor.
The Best Onions to Use for Onion Dip
The secret to the best onion dip lies in the type of onions you use. Yellow onions caramelize beautifully and offer a sweet, rich depth. Red onions add a slight bite and color, while shallots bring a more delicate flavor. You can even mix two types for complexity.
The Thermomix makes the process effortless—you sauté and chop directly in the bowl. No extra pans. No mess.

How to Make Onion Dip with Thermomix: Step-by-Step
Making onion dip manually means 30+ minutes of stirring and careful temperature control. With Thermomix, it’s all automated. Here’s a simple guide:
- Chop onions: Add halved onions to the bowl and chop for 5 seconds/speed 5.
- Caramelize: Add olive oil and cook for 20 mins/120°C/speed 1 with the measuring cup off.
- Blend base: Add sour cream or Greek yogurt, cream cheese, salt, pepper, garlic powder, and parsley.
- Mix: Combine for 10 seconds/speed 3. Chill and serve!
Make It Lighter or Richer – Your Choice
The great thing about onion dip is its versatility. Want it lighter? Use Greek yogurt or low-fat sour cream. Prefer it richer? Go full-fat with sour cream and cream cheese.
You can also add a splash of Worcestershire sauce or Dijon mustard to boost umami without changing the creamy consistency.

Delicious Pairings for Onion Dip
Wondering what to serve with your onion dip? Here are a few easy ideas:

- Sliced cucumber or carrots – for a lighter option
- Mini toasts or bagel crisps – great crunch
- Roasted sweet potato wedges – surprising and satisfying
Want to go gourmet? Serve the dip alongside grilled steak or chicken for an unexpected creamy garnish.
How Long Does Homemade Onion Dip Last?
Homemade onion dip lasts about 3–5 days in the fridge if stored in an airtight container. Make sure it’s fully chilled before sealing to prevent condensation.
Stir before serving, especially if it’s been sitting. The flavor actually improves after a few hours in the fridge as the ingredients meld together.
Can You Freeze Onion Dip Made in Thermomix?
While technically possible, freezing isn’t ideal for dairy-based dips like this. Once thawed, the texture may split or become watery.
If you must freeze it, freeze without the dairy base—just the caramelized onion mixture. Then thaw and mix in the dairy fresh before serving for best consistency.
Is Onion Dip with Thermomix Healthier Than Store-Bought?
Absolutely. When you make onion dip from scratch, you skip preservatives, artificial thickeners, and excess sodium. You control the ingredients, flavors, and fat levels.
Use Greek yogurt for protein, olive oil for healthy fats, and skip any added sugar. This makes it perfect for low-carb or whole-food-style diets.
Ideas to Customize Your Onion Dip Recipe
Want to spice things up? Here are some delicious upgrades:
- Add bacon bits for a smoky twist
- Mix in caramelized shallots for sweeter depth
- Top with chopped chives or scallions for freshness
- Fold in blue cheese crumbles for sharpness
You can even turn it into a warm baked dip by placing it in the oven with shredded mozzarella on top.

Perfect for Meal Prep and Events
Because the flavor deepens over time, this dip is ideal for make-ahead meal prep. Just make it the day before your event and chill overnight.
Planning a party? Serve it in small ramekins for individual dipping or use as a sandwich spread.
