Baked Onion Dip

Cheesy, hot, baked Vidalia Onion dip with chunks of real sweet onions and loads of cheese is a perfect party appetizer. Served up with French bread slices or toasted baguettes, I love making hot onion dip for my own get-togethers.

This not-so-ordinary dip has the perfect bold flavors of an onion balanced with melty cheese. With super simple and readily available ingredients, this dip is also cost effective to make and won’t break the bank, which is one of the parts I like the best.

One of my very favorite dips to serve and to eat, I really hope this is one of your most requested recipes after your next party.

Dip Ingredients

Unlike my other cold dip recipes that are mainly meant as a chip dip (like ranch dip or cucumber dip), this onion dip is served hot.

• Sweet Onions: Vidalia, Sweet Yellow Onions, or Maui can all be used.
• Cheese: Shredded Swiss and Gruyere. Typically you can find these cheese mixes pre-shredded in a bag and already combined.
• Real mayonnaise
• Seasonings: garlic powder, salt, black pepper
• Chopped green onions

How to make Baked Onion Dip

1. Preparation: Begin by preheating your oven to 350°F (175°C). Then, take a nonstick baking pan and lightly grease it with cooking spray. Set this aside for later use.
2. Mix Ingredients: In a large mixing bowl, combine the following ingredients: 2 cups of finely chopped sweet onions, 1 1/2 cups of the shredded Swiss and Gruyere cheese mix, 2 cups of real mayonnaise, 1 teaspoon of garlic powder, 1 teaspoon of salt, and 1/4 teaspoon of pepper. Stir these together until everything is well mixed.
3. Transfer to Baking Pan: Once your onion mixture is ready, take it and spread it evenly into the prepared baking pan. Make sure the mixture is spread out evenly for consistent baking.

1. Bake: Place the pan in the preheated oven and bake the onion dip for 30 minutes. You’ll know it’s done when the cheese has completely melted and the onions have softened and sweetened slightly from the heat.
2. Cool and Serve: After baking, remove the pan from the oven and let the dip stand for about 5 minutes to cool down a bit. This resting period allows the flavors to meld together even more.
3. Garnish and Enjoy: Just before serving, sprinkle some chopped green onions on top of the dip for a fresh, colorful garnish. Serve the warm onion dip with toasted slices of French bread for dipping.

You will find that this dip will have some oil from the cheese and mayo ingredients rise to the top. This is totally normal in the baking process.

What dippers to serve with Onion Dip

• Traditionally I like sliced baguettes that are are either served as their natural state (soft bread) or crisped up on the oven. You can find the already crispy baguette pieces that are more like hard crouton texture in containers near the bakery in most stores.
• We have a whole list of best vegetables for dipping if you need suggestions.
• Serve in a bread bowl. We do that for our Knorr spinach dip and walk you through how to make the perfect bread bowl with images if you need help.

A NOTE FROM MY KITCHEN: One suggestion that isn’t present in this dip recipe is to add an additional TOP layer of golden cheese prior to baking and I plan on doing that myself in future renditions of this dip.
