A Utilitarian Soup
It’s cold as I write this. Polar vortex, bring-the-pets-inside, everything is frozen cold. So you’d better believe that soup is on the menu.
Battling a whipping wind demands a hearty soup. Something that feels more substantial than a wimpy broth.
This onion soup fits the bill nicely.
Another bonus is that it’s delightfully inexpensive. Sometimes diets get a bad rap for being pricey, but that doesn’t have to be the case.
You’re really only looking at onions, beef broth, and garlic. You’ll likely already have olive oil, salt, and pepper on hand, and the Madeira and parsley are optional.
Caramelizing Onions
The trick to caramelizing onions is to give them plenty of time without allowing them to burn. It’s a process.
Olive oil works nicely for this job because it doesn’t burn as easily as some other fats.
Don’t get impatient and crank the heat. Set your cooker to sauté and let the magic happen in its own time.
Tongs can be handy for flipping the onions early in the process, but any spoon will do once they’re soft.
Keep them going until they’re very soft and brown. Then you can add your broth.
