In a large skillet over medium heat, cook the chopped 1 pound bacon until crispy. About 20-25 minutes. Use a slotted spoon to transfer the cooked bacon to a paper towel-lined plate to drain excess grease. Drain all but about 2 tablespoons of bacon grease in the skillet.
In the same skillet with the remaining bacon grease, add the 2 large onions and cook over low heat, stirring occasionally, for about 20 minutes or until they are golden brown and caramelized.
Once the onions are caramelized, add the ½ cup pure maple syrup, ¼ cup dark brown sugar, ¼ cup apple cider vinegar, 1 tablespoon thyme, ¼ teaspoon kosher salt, ¼ teaspoon black pepper, and ¼ teaspoon smoked paprika (if using) to the skillet. Stir well to combine.
Add a splash of bourbon to create bourbon bacon jam.
Bring the mixture to a simmer over low heat and let it cook for about 15-20 minutes, stirring occasionally until it thickens to a jam-like consistency. The jam should coat the back of a spoon when it's ready. Return the bacon to the pan and stir to combine
Remove the skillet from the heat and let the Maple Bacon Onion Jam cool to room temperature. Once cooled, transfer it to a glass jar or an airtight container. I typically store it in a glass mason jar.
Notes
StorageStore the jam in the refrigerator for up to 5 days.For longer storage, the jam can be stored in an airtight container in the freezer for up to 3 months. Be sure to label it with the date and contents.To Thaw: Place the container in the refrigerator to thaw overnight.Tips
Be sure to use a large skillet. A too-small skillet will crowd the bacon making it take longer to crisp and cook.
Cook the onions over low heat to caramelize the natural sugars in the onions without burning them.
Add a pinch of crushed red pepper flakes for a little heat.
Puree the jam using a hand-held blender or food processor for a smoother consistency.
