What You’ll Need
Let’s gather the essentials to create this delectable dip!
- 2 tablespoons olive oil
- 2 large yellow onions, finely chopped
- 1 medium shallot, thinly sliced
- 3/4 teaspoon salt
- 1/4 teaspoon black pepper
- 1 teaspoon granulated sugar
- 3 garlic cloves, minced
- Pinch crushed red pepper flakes (optional)
- 3/4 cup full-fat Greek yogurt or sour cream (both work wonders!)
- 2/3 cup mayonnaise
- 3/4 cup finely grated hard Italian-style cheese (think Parmigiano-Reggiano)
- 6 ounces shredded mozzarella cheese
Feel free to experiment a little! If you want a slightly tangy kick, use crème fraîche instead of yogurt. For a smoky flavor, consider adding some smoked Gouda to the mix.
Step-by-Step Instructions
- Preheat your oven to 375°F and lightly grease a small to medium baking dish. Set this aside.
- In a large skillet, warm the olive oil over medium heat. Add in the chopped onions and shallots, then sprinkle with salt, pepper, and sugar.
- Cook slowly for about 20–25 minutes, stirring occasionally. Your goal? Deep golden, soft, and ridiculously sweet onions.
- Stir in the minced garlic and red pepper flakes, if you’re feeling a bit adventurous with heat, and cook for about 1 minute until fragrant. Remove from heat.
- In a medium bowl, combine your yogurt or sour cream, mayonnaise, grated cheese, and shredded mozzarella. Stir until you have a smooth, creamy mixture.
- Fold the warm onion mixture into the creamy cheese base until everything is well combined.
- Spoon this heavenly mixture into the prepared baking dish and spread evenly.
- Bake uncovered for 22–25 minutes, or until the dip is hot, bubbly, and lightly golden on top. For an extra nice finish, broil briefly at the end for that beautiful color.
- Let it rest for about 5 minutes before diving in. Warm it up with crackers, toasted bread, or fresh veggies—it’s an open invitation to indulge!

Best Ways to Enjoy It
Now that you have this wonderfully rich dip ready, let’s talk about how to serve it.
This dip pairs beautifully with an array of dippers. Think crunchy crackers, crispy tortilla chips, or warm toasted baguette slices. Fresh veggies—like crisp cucumber or bell pepper sticks—offer a refreshing contrast to the creamy mixture. You could even layer it up on a charcuterie board, surrounding it with a selection of cured meats, pickles, and olives for an impressive display. Your guests will be charmed!
Keeping Leftovers Fresh
If you happen to have any leftovers (though that’s rare with this dip!), it’s best to store them in an airtight container in the refrigerator. You can enjoy it for up to three days after baking. Reheat gently in the oven or microwave until warmed through. Just give it a stir before serving—it’s a fast and easy way to keep the flavors bright and enjoyable!
Helpful Cooking Tips
Here are a few tips to elevate your experience when making this dip:
- Patience with onions: Caramelizing the onions slowly is critical. Rushing this step could lead to bitterness rather than the lovely, sweet flavor we’re aiming for.
- Grate your cheese: Using fresh cheese instead of pre-shredded guarantees a creamier consistency. Pre-shredded cheeses often contain anti-caking agents that prevent optimal melting.
- Customize your spices: Don’t hesitate to add herbs like thyme or chives for an added depth of flavor.
Creative Twists
Feel free to mix things up! You could add chopped spinach for a note of freshness or even mix in a little blue cheese for added sharpness. Swap out the mozzarella for a pepper jack if you’re craving a spicy kick. This recipe is quite flexible, allowing you to cater to various palates.
