Do you love caramelized onions as much as I do? They’re one of those foods that make my eyes roll back into my head just a little bit every time I eat them. They’re not at all like the raw onions from which they transformed. This is another piece of culinary alchemy… the long, slow application of heat to a raw, fiery onion to transform them into something meltingly tender, sweet, savoury, and subtle.
I love to tuck them into sandwiches, toss them onto pizzas and salads, stir them into pasta or chip dip, and bake them into bread and stuffing. I use them at least twice a week and sometimes more. I always have a supply on hand for whatever caramelized onion whim might strike.
How do I keep these deep brown, fragrant beauties on hand when they take so long to make?
I employ my slow-cooker and make mega-batches. The slow-cooker is the perfect onion-caramelizing vessel for a multitude of reasons.
- It cooks at a low enough temperature that after a good stir an hour in, and another good stir three hours into the cook time, you don’t have to mess with it any more. Bonus: no need to stand stirring at the stove when you could sit sipping tea and reading books!
- It holds a whole mess of onions (technical term) which makes it ideal for big batches of caramelized onions which is really the only logical way to make them because if you’re cooking it for that long, you want a lot to show for it, right?
- If you want, you can just remove half of the onions at the end of the cooking time, add the remaining ingredients for your French Onion Soup directly to the caramelized onions in the slow cooker, and let it heat up while you prepare your croutons. Voila! Almost instant soup with only one pot dirtied. That is a very nice thing indeed!
- I’ll admit it, it smells deliciously and strongly of caramelizing onions while it cooks. Just plug in your slow cooker outside. I do this all the time to keep myself from feeling ravenous while it cooks. It also helps keep my super-sniffer husband from being overwhelmed by the smell. Can’t just move your stove outside, can you?
How do I make French Onion Soup from these caramelized onions?
Are you ready for the easiest French Onion Soup recipe of all time? Take half of the onions you caramelized and put them in a pan with 1 1/2 cups each of beef broth and chicken broth, a splash of red wine, and heat it up.
Make some big soup croutons from thick slices of French bread, drop one on a bowl of the soup, cover with grated or thinly sliced Swiss cheese and pop under the broiler until melted, bubbly, and browned in places. Ta da!
