These caramelized onions prepared in the crockpot are easy, aromatic, and flavorful.
I had quite a few recipes over the weekend that needed caramelized onions. Instead of preparing them over the stove, which requires me to pay attention to them, these onions caramelized themselves in the crockpot while I slept. When I woke up Saturday morning, the house smelled wonderful! Not only did I have perfectly caramelized onions, I also had liquid gold (aka onion flavored beef broth).
Stay tuned over the next week for the recipes I used these caramelized onions for, including Portobello Mushroom Burgers, French Onion Risotto, and French Onion Grilled Cheeses. I also froze half a batch of the caramelized onions to use for future recipes.
Caramelized Onions (Crockpot)
·5-6 large onions
·½ cup homemade beef broth
·½ cup water
·4 TBS butter
·2 TBS port wine (optional)
Peel onions and cut off stems. Chop onions in half and place in the bottom of a 6-quart crockpot. Pour broth and water over the onions. Cut butter into smaller pieces and place on top of the onions. If desired, drizzle with port. Cover and cook on low for 10-12 hours (I find it convenient to cook the onions overnight).
Remove onions from crockpot and use as needed in recipes/meals. (You may want to chop into thinner slices when using caramelized onions as an ingredient). Save onion flavored beef broth for future recipes that call for beef broth. Freeze extra caramelized onions in cupcake liners for up to 3 months.
