Caramelized onions have a multitude of uses, whether they are the base for your classic French onion soup recipe or if you want to stuff them into omelettes or sandwiches. The problem is that they take a long time to make, though, at approximately forty-five minutes to an hour on the stove where you need to keep a watchful eye to prevent burning. Luckily, Judith, the author of The Midnight Baker recipe blog, came up with this slow cooker caramelised onions recipe, which takes a long time as well, but is almost entirely hands-off during the cooking time, and produces a large number of onions for all your favourite dishes. The preparation of this caramelised onion recipe is very easy too, as the onions are the only thing that requires slicing. This dish is just a matter of combining the thinly sliced onions with some butter before letting the crock pot do its magic.

The secret to exceptional caramelised onions is to cook them low and slow until their sugars render and the sliced onions turn golden. It is also incredibly important to slice the onions as thin as you can so that they cook evenly. The crockpot is an ideal vessel for this caramelised onion recipe because it cooks at a low heat automatically, and you won’t have the risk of burning the onions like you would on the stove. Since you will be starting with a lot of onions, it is crucial that you use a larger crockpot, approximately four to six quarts in size. If you aren’t sure what size slow cooker you have, a great way to tell is to add a quart of water at a time until it comes to the top of the slow cooker. Whatever number of quarts the crock pot can hold is the amount of food it can contain as well. If you have a smaller crockpot, simply reduce the number of onions in this onion recipe, as it is easy to scale back.

Once you have plenty of these golden, sweet onions on hand, they will be ready for any comfort meal you want during the week. Just store in the refrigerator until you are ready to add them to a good comfort soup by mixing them with beef stock or add them to sandwiches, pizzas or pasta. These onions will be particularly delicious in a grilled cheese sandwich recipe for lunch, consisting of gooey gruyere cheese. They can even be added to elegant holiday apps, like crostini with cheese or stuffed into phyllo with tangy cranberries. While crockpot recipes are usually a full meal ready to enjoy at the end of a long day, these onions are unique because they can be stretched through multiple meals during the week.

Great crockpot recipes are the ones that produce results just as good as the other cooking methods, but with much less work. This slow cooker recipe results in the sweetest and golden looking onions that everyone will be surprised were done in the crockpot. Besides the occasional stir, the crockpot will do most of the work in turning raw onions into versatile golden onions that can be used in several ways. Judith likes to add some fresh thyme to her onions for an earthy undertone, but you can omit it if you like. Alternatively, consider stirring in a sprig of fresh rosemary for a stronger taste, or leave plain if you plan on using the onions in a variety of ways during the week. Thank you to Judith, the author of The Midnight Baker recipe blog, for sharing her slow cooker caramelised onions recipe with us.
