Caramelized Onion Butter
-
1Melt 2 Tablespoons of butter in a cast-iron or non-stick skillet over medium heat. Add onions, season with salt and pepper, and stir to combine.
-
2Cook onions slowly for at least 20 to 25 minutes, stirring occasionally to prevent burning. You may need to adjust your heat to low as well. Cook onions until they become translucent and golden brown and then allow to cool.

3Cream butter in small bowl using a fork or electric mixer.
-
4Gradually blend in caramelized onions. Butter mixture can be used while still soft; or it can be rolled into a cylinder in parchment paper or plastic wrap and refrigerated or frozen, then sliced into thin rounds.
-
5Flavored butter can be stored a couple days in the refrigerator or it can be frozen for several weeks.
