Red Onion Dip Recipe
This creamy roasted red onion dip is just the thing for a crowd or a cozy night in! With rich, sweet onions folded into a blend of cream cheese, sour cream, and a hint of Parmesan, this dip is packed with flavor. Serve it up with thick potato chips or crunchy veggie sticks for a snack that everyone will love.
Making red onion dip starts with diced red onions, tossed in olive oil, salt, and pepper, then roasted until they’re tender and just a little charred around the edges. The cooked onions are then folded into a smooth blend of cream cheese, sour cream, and a bit of Parmesan for an extra touch of savory depth. Lemon juice and garlic add brightness, balancing all that rich flavor and making each bite seriously satisfying.
Serve it with thick, ridged potato chips or pita chips for that perfect dip-and-crunch combo or a fresh platter of veggies if you’re in the mood for something lighter. And if you’re a fan of warm dips, pop it in the oven to take it up a notch in coziness.
I like this dip for its flavor balance of savory and sweet. You can also make it ahead of time, and the flavors will get even better overnight. If you have any extra, try spreading it on sandwiches or using it as a topping for baked potatoes.
Ingredients for Roasted Red Onion Dip
- 2 cups red onion, diced
- 1 tablespoon olive oil
- 1/2 teaspoon salt, or to taste
- 1/4 teaspoon pepper, or to taste
- 8 ounces cream cheese, room temperature
- 1/2 cup sour cream
- 1 teaspoon Worcestershire sauce
- 2 teaspoons lemon juice
- 1 teaspoon garlic, minced
- 2 tablespoons mayonnaise
- 1/4 cup grated Parmesan cheese
Ingredient Notes
- Red Onion: Red onions add a hint of sweetness and deep flavor when roasted. If you prefer a milder taste, you can substitute with yellow onion, though it will give a slightly different flavor.
- Cream Cheese:Room temperaturecream cheese blends smoothly and gives the dip a rich, creamy base.
- Sour Cream: Lightens the texture of the dip while adding a slight tang that complements the roasted onions. Plain Greek yogurt is a good substitute.
- Worcestershire Sauce: I use vegan Worcestershire sauce for adding a savory depth to the dip. If you need a substitute, soy sauce with a few dashes of hot sauce can work well.
- Lemon Juice: Freshly squeezed lemon juice brightens the flavors and balances the richness of the cream cheese and mayonnaise.
- Garlic: Minced fresh garlic adds a subtle aromatic kick to the dip. For a more robust flavor, try roasting the garlic with the onions.
- Mayonnaise: Mayonnaise enhances the creamy texture and adds a slight tang. Use vegan mayo if needed.
- Parmesan Cheese: Adds a nice bit of sharpness to balance out the creaminess. For a milder option, try finely grated mozzarella or leave it out for a slightly lighter dip.
How to Make Roasted Red Onion Dip
STEP ONE: Preheat the oven to 400°F. Line a small baking tray with parchment paper.
STEP TWO: Prepare the onion. In a medium bowl, toss the diced red onion with the olive oil, salt, and pepper. Spread the onion evenly on the prepared baking tray.
STEP THREE: Roast the onion. Place the tray in the preheated oven and roast for 20 minutes, stirring occasionally, until the onion is softened and the edges begin to char. Remove from the oven and allow to cool.
STEP FOUR: Make the dip. In a large mixing bowl, beat the softened cream cheese with an electric mixer for 1 minute, until creamy. Add the sour cream, Worcestershire sauce, lemon juice, garlic, mayonnaise, and Parmesan cheese. Beat until smooth. Stir in the roasted onion just until combined. Adjust seasoning taste and serve.
Warm Dip Option: For a warm dip, transfer to an oven-safe serving dish and bake in a 350°F oven for 15 minutes, until heated through.
FAQ
- Can I make this dip in advance? Yes! This dip actually tastes even better after a few hours as the flavors meld together. Just prepare it as directed, cover, and store it in the fridge until ready to serve.
Can I use a different type of onion? Absolutely. Yellow or white onion can work if you don’t have red onions on hand, though they won’t have the same touch of sweetness red onions give when roasted. - How do I make this vegan? For a plant-based dip, use vegan cream cheese, sour cream, mayonnaise, and Parmesan cheese. Ensure the Worcestershire sauce is vegan, or use soy sauce as a substitute.
- Can I serve this dip warm? Yes! For a warm version, bake the dip in an oven-safe dish at 350°F for 15 minutes until heated through.
Storage
- Store any leftover dip in an airtight container in the refrigerator. Stir well before serving.
