In my kitchen, there's a special place for homemade condiments like this Caramelized Onion and Bacon Jam. I had a few friends over for dinner, and I decided to make something tangy and sweet. The magic really happens when the onions break down and meld with the bacon and spices, creating a symphony of flavors that can enhance even the simplest of meals.

As I experimented with different ingredients, I found that a touch of balsamic vinegar at the end added the perfect balance of acidity to the sweetness of the onions. If you’re patient and let it cook low and slow, the flavors really deepen, creating a jam that is bursting with taste.

Understanding the Ingredients

The foundation of this Caramelized Onion and Bacon Jam is the onions. Opting for sweet onions like Vidalia or Walla Walla will amplify the sweetness of the jam, balancing beautifully with the savory bacon. When slicing your onions, aim for uniform thickness; this ensures they caramelize evenly without burning. The caramelization process draws out natural sugars, transforming the onions into a rich and exquisite base for the jam.

Bacon adds a smoky, savory depth to the jam, but the type you choose can significantly influence the flavor. I prefer using thick-cut bacon as it renders fat slowly and becomes wonderfully crispy. If you’re looking for a leaner option, turkey bacon can work, but you might want to add a touch more olive oil to ensure the onions caramelize properly.

Perfecting the Cooking Technique

While it may be tempting to crank up the heat to speed up caramelization, practice patience. Cooking the onions over medium-low heat allows them to release moisture and develop that beautiful golden color without burning. Stirring every few minutes not only prevents sticking but also helps ensure even caramelization. You’ll know they’re ready when they are soft and glossy, with a deep, golden hue. This process typically takes about 30-40 minutes, so it’s well worth the wait.

Adding the brown sugar and balsamic vinegar after caramelizing the onions enhances the depth of flavor. Brown sugar helps to further caramelize the onions while balsamic vinegar adds a tangy sweetness. Keep an eye on the mixture as it simmers; you want it to reduce to a thick, jam-like consistency. If it becomes too thick, a splash of water or a bit more vinegar can help adjust the texture.

Ingredients

For Caramelized Onion and Bacon Jam

4 large onions, thinly sliced
6 strips of bacon, diced
1/4 cup brown sugar
1/4 cup balsamic vinegar
1 tablespoon fresh thyme, chopped
Salt and pepper to taste

Instructions

Cook the Bacon

In a large skillet, cook diced bacon over medium heat until crispy. Remove bacon with a slotted spoon and drain on paper towels.

Caramelize the Onions

In the same skillet, add sliced onions. Stir frequently over medium-low heat for about 30-40 minutes until they are golden and caramelized. If they stick to the pan, add a splash of water.

Add Sugar and Vinegar

Once onions are nicely caramelized, stir in the brown sugar and balsamic vinegar. Bring to a simmer.

Combine Ingredients

Add the cooked bacon and fresh thyme to the onion mixture. Season with salt and pepper as desired. Cook for an additional 10-15 minutes, allowing flavors to meld.

Cool and Store

Let the jam cool to room temperature, then transfer to a jar. Store in the refrigerator for up to 2 weeks.

Pro Tips

For a slightly spicier version, consider adding a pinch of red pepper flakes during cooking.

Storage and Shelf Life

Once your jam has cooled, transfer it to a clean, airtight jar. This delicious spread can be safely refrigerated for up to two weeks. If you plan to enjoy it beyond that, consider freezing portions. Use ice cube trays for easy portioning—once frozen, store the individual cubes in a sealed bag. This way, you can thaw just the amount you need for quick meals or snacks.

I recommend labeling your jars with the date you made the jam. This not only helps you keep track of freshness but also makes it easier to plan future meals. As it sits, the flavors may deepen when stored, creating a more complex and savory jam that is great to have on hand.

Serving Suggestions

Caramelized Onion and Bacon Jam is incredibly versatile. While it’s fantastic on toast or bagels, it also elevates dishes when used as a topping. Try it on a juicy burger to add a gourmet twist, or spread it atop grilled chicken for an instant flavor upgrade. It pairs wonderfully with cheese boards too—serve it alongside creamy cheeses like Brie or sharp Cheddar for impressive entertaining.

For a unique appetizer, spread the jam on small puff pastry rounds or crostini and top with a dollop of goat cheese or crème fraîche. This combination not only looks beautiful but also adds a rich texture and tangy contrast to the sweet and savory jam. Your guests will surely be asking for the recipe!
