Roasted Caramelized Onion Dip

This creamy roasted onion dip is an irresistible take on my childhood favorite chip dip. It’s made with fresh ingredients like roasted onions, garlic, Greek yogurt, and lemon juice. It’s an easy dip recipe you can make ahead of time, and it’s perfect for party season!

This roasted onion dip is my grown-up take on the classic French onion dip I remember from childhood — and honestly, it might be even better. It has all that familiar, savory onion flavor, but it’s made with simple, whole ingredients that give it a fresher, more irresistible feel.

I love how easy this dip is to pull together. It uses just six everyday ingredients, skips the mayo entirely, and leans on Greek yogurt for a creamy, tangy base. It’s also a dream for entertaining since you can make it a day or two ahead and let the flavors deepen in the fridge.

I usually serve it with plain salted potato chips or fresh veggies, but it’s great with just about anything scoopable — pretzels, crackers, pita, tortilla chips, even sliced apples or pears. It fits right in on a snack board, pairs naturally with other appetizers, and if there’s any left (rare, but it happens), it’s surprisingly good smeared onto a roast beef sandwich.

What should the onions look like when they’re finished roasting?

Make-ahead

This dip is great to make in advance, as the flavors deepen after a day in the fridge. It will last for at least 4 days in your fridge, so it’s a great recipe to prep ahead for a party!

• ▢ 2 tablespoons lemon juice

Instructions 

• Turn your oven to 375 degrees Fahrenheit and line an 18×13"  baking sheet with parchment paper.
• Add the sliced onions and the garlic to the baking sheet and toss with the oil, salt, and 2 tablespoons of water.

Notes

You can dig into this dip right away (it’s delicious!) but the flavors come together best after you let it rest for a couple hours in your fridge.
