This Caramelized Onion and Bacon Dip is the perfect blend of sweet, smoky, and creamy flavors all in one bowl. Rich caramelized onions bring a sweet depth that pairs beautifully with crispy, salty bacon pieces. It’s smooth and thick, making it great for dipping chips, crackers, or fresh veggies.
I love making this dip whenever friends come over because it’s always a crowd-pleaser. The slow cooking of the onions brings out the best sweetness, while the bacon adds a little crunch and that unmistakable smoky taste. I usually make it ahead of time so the flavors can meld together, which makes it taste even better the next day.
My favorite way to serve this dip is with a big bowl of kettle-cooked potato chips or some sturdy pita chips for scooping. It’s also great as a spread on toasted bread during casual get-togethers. Honestly, once you try it, you’ll find yourself reaching for this dip at every party and snack time!
Key Ingredients & Substitutions
- Yellow Onions
- These are perfect for caramelizing because of their natural sweetness. White onions are a good alternative, but they have a sharper taste. Red onions can work if you want a milder, slightly fruity flavor.
- Bacon
- Bacon adds smoky crunch that balances the dip's creaminess. You can swap it with turkey bacon for a leaner option or smoked sausage bits if you prefer.
- Cream Cheese
- This creates the creamy base. Neufchâtel cheese is a lower-fat substitute, or you can use a mix of Greek yogurt and cream cheese for tang and creaminess.
- Sour Cream & Mayonnaise
- They add richness and smooth texture. For a lighter version, swap mayonnaise with Greek yogurt or use all sour cream. Just keep the creamy balance.
- Cheese
- Mozzarella gives gooey meltiness, while Parmesan adds sharpness. You could use cheddar or Gruyère to vary the flavor.
How Can I Perfectly Caramelize Onions Without Burning Them?
Caramelizing onions takes patience but it’s worth it for deep, sweet flavor. Here’s how to get it right:
- Slice onions thin and evenly to ensure they cook uniformly.
- Cook on medium-low heat—too high and they burn or dry out.
- Stir occasionally, about every 5 minutes, scraping the pan to prevent sticking.
- Add a pinch of salt to help draw out moisture and speed caramelization.
- If onions start sticking too much or browning too fast, lower the heat and add a splash of water.
- Be patient—it can take 40-50 minutes, but the deep brown color and sweet aroma mean you’re done.
Slow cooking is the key. Rushing this step will leave the onions with a sharp taste rather than a mellow sweet flavor.
Equipment You’ll Need
- Large skillet – perfect for slowly caramelizing onions without burning them.
- Mixing bowl – makes combining cream cheese, sour cream, and other ingredients easy.
- Sharp knife – helps you slice onions thin and chop bacon evenly.
- Baking dish or oven-safe dip bowl – holds the dip while it bakes and browns beautifully.
- Wooden spoon or spatula – great for stirring onions gently as they cook.
Flavor Variations & Add-Ins
- Swap bacon for cooked pancetta or diced ham for a different smoky pork flavor.
- Add chopped jalapeños or a dash of cayenne for a spicy kick that balances the sweetness.
- Mix in shredded sharp cheddar cheese instead of mozzarella for a bolder, tangier taste.
- Stir in chopped fresh herbs like chives or parsley at the end to add fresh, bright notes.

How Much Time Will You Need?
This recipe takes about 15 minutes to prepare the ingredients, 40-50 minutes to caramelize the onions, plus 20-25 minutes baking time. In total, expect around 1 hour 15 minutes from start to serve, but much of this is hands-off cooking time.
Step-by-Step Instructions:
1. Caramelize the Onions:
Heat olive oil in a large skillet over medium-low heat. Add the thinly sliced onions and a pinch of salt. Cook slowly for around 40-50 minutes, stirring every few minutes, until the onions are deeply browned and sweet. Be patient—this slow cooking develops the rich flavor.
2. Cook the Bacon:
While the onions cook, place the bacon strips in a separate pan over medium heat. Fry until crispy, then drain on paper towels. When cool, chop the bacon into small pieces.
3. Mix the Dip Ingredients:
Preheat your oven to 375°F (190°C). In a mixing bowl, combine the softened cream cheese, sour cream, mayonnaise, minced garlic, shredded mozzarella, grated Parmesan, and thyme leaves. Add salt and pepper to taste. Fold in the caramelized onions and half of the chopped bacon.
4. Bake the Dip:
Transfer the mixture to an oven-safe baking dish or dip bowl. Sprinkle the remaining chopped bacon on top. Bake for 20-25 minutes until the dip is bubbly and golden on top.
5. Serve and Enjoy:
Take the dip out of the oven and let it cool for a few minutes. Garnish with fresh thyme sprigs if you like. Serve warm with toasted baguette slices or your favorite crackers for dipping.
Can I Make This Dip Ahead of Time?
Yes! Prepare the dip a day before, cover it tightly, and refrigerate. When ready to serve, bake it fresh to warm through and get that bubbly top.
Can I Use Frozen Onions for Caramelizing?
Fresh onions work best for caramelizing because frozen ones release too much water, which prevents proper browning. If needed, thaw and drain frozen onions before using, but results may vary.
What Can I Use Instead of Bacon?
You can substitute turkey bacon or cooked pancetta for a different smoky flavor. For a vegetarian option, try smoked mushrooms or sun-dried tomatoes to add depth without meat.
How Should I Store Leftovers?
Store leftover dip in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F (175°C) until warmed through, stirring halfway for even heating.
