I caramelized four big onions this weekend. How should I use them? What is your favorite recipe that incorporates caramelized onions?

You can freeze them in portions in ice cube trays, so all your burgers and steaks henceforth can have a nice dollop of them.

It's a little warm here for onion soup, but you could do that too.

Throw them in a rice cooker with brown rice and some oil.

Mujadara is the only thing I think of when I think of carmelized onions.

Everything. Everything is appropriate for good caramelized onion. Yes even popsicles.

My inclination would be to serve generously over a grilled protein, or sautée some mushrooms and whatever other veggies scraps are on hand to make a delicious soup, do an easy roux for extra tasty points.

Grilled cheese sandwiches! I think one onion's worth of caramelized onion per sandwich is about right. I like either a brie or a sharp cheddar. If you're using a non-melty cheese, get some non-sliced American cheese at the deli counter, grate both cheeses up and toss them together before making your sandwich.

Pasta, olive oil or butter, parmesan cheese. Maybe a little bacon or pancetta.

Before I stopped eating dairy, I used make an onion tart with sauteed onions and swiss cheese.

Freezing them in ice cube trays, yes.

Pissaladier - I have not used this exact recipe (I've used home-made or purchased pizza dough in the past)

Tamarind chickpea curry - Surprisingly delicious.

Omelette, with more onions than egg. Warm about a half cup or cup of them up slightly, then start the eggs in a larger pan than you think you need so you get a thin omelette, then drop them in and fold and eat. Add a bit of cheese if that's your thing.

Beets and Caramelized Onions with Feta

This is really good. Works with roasted beets or pickled beets.

Butternut squash and caramelized onion galette from Smitten Kitchen.

Sliders or burgers with caramelized onions, arugula, melted cheese, and a little ketchup.

Dirty rice. Fry sliced mushrooms and onions together until the onions are caramelised. (Or warm your pre-cooked onions and fry some mushrooms.) Chuck into the pan the white rice you have previously boiled. Mix together, serve with green veg or salad. Garnished nuts might be nice. Or not, doesn't matter, it's a cheap-and-easy-feed-lots-with-little kind of recipe. Rice for 5 or 6 people will take two fistfuls each of onions and mushrooms.

Koshari! Pasta, rice, chickpeas, and lentils with a tomato sauce and a vinegar sauce and the onions on top ... decadent.

I can also recommend the smitten kitchen dish, it's super yummy. I love to put caramelized onions on a pizza - sometimes alone, sometimes with chicken and BBQ sauce. The possibilities are endless!

Ooh, also, I like to drape them over perogi, especially if you can get some really good quality perogies!

in scrambled eggs.

also in sauteed grated zucchini, but that's a whole recipe.

Seconding that caramelized onions make a really great pizza topping. My partner recently made a pizza with balsamic caramelized onions, prosciutto, blueberries, basil, mozzarella and soft unripened goat cheese. For a heavier pizza we've paired the caramelized onions with crumbled sausage & Italian seasoning.

All the onion burgers, all the time. Hamburger patty is not optional, but does not have to dominate. Cheese of course, grilled mushrooms are also nice, or grill some red and green bell peppers.
Grill the bun before assembly, preferably in the same drippings as the caramelized onions.

Also, slice some potatoes and spend an enormous amount of time slowly frying them. Electric skillet is good, cast iron skillet is even better. Brown them tatters. Then add sliced onion. More frying ensues. Some like their condiments, but I just add salt and devour as (deity of your choice) intended.

This caramelized onion+rosemary dip is SUPER yum and happens to be vegan.

Onion tart/s with either thyme or oregano notes.
For extra flavour combo with the onions, roll up the pastry edge with Parmesan or similar, seal the edges with a fork n milk. Fit it into a square or rectangle tin. (I also make these as little tarts with shop bought cases sprinkled with a bit of Parmesan.) Blind bake for a bit til it’s got a light tan. Take out of oven and spoon in a layer of the onions, add roughly torn feta bits. Bake til it’s a bit melty and then shower the tart with fresh oregano leaves. You can eat it hot or cold. Lots of caramelised onion tarts are quiches but you don’t need milk or eggs to make this as you could use vegan pastry and skip the animal cheese for substitutes. I think the onions and lashings of fresh oregano or thyme in a crunchy mouthful is The Best food combo for any meal in the day.

I make a pizza with caramelized onions, a generous sprinkling of thyme and fontina cheese. Sooo good!

They're good on a tunafish sandwich, with capers.
They're good with pasta, with garlic and red pepper flakes and capers.
They're good on pizza, with goat cheese and black olives.
They're good on hamburgers, with cheddar cheese and bacon.

They go really well with a salty element with contrasting texture, because they're kind of gooey. That's part of their charm, but it needs offsetting.

My favorite is slicing a broiled flank steak thinly and topping thick toast with that, some caramelized onions with a bit of paprika and some warmed sour cream with horseradish mixed in. Yuuummm.

Also homemade pizza with caramelized onions, creme fraiche, and crispy bacon.

My husband’s chili recipe makes copious use of caramelized onions. (I think the recipe is pretty generic otherwise.)

Came in to say pizza topped with goat's cheese, gorgonzola, roasted pears and caramelized onions would be divine!

Patty Melt uses about 1/2 onion per sandwich, maybe a bit more.

Quiche Lorraine is the most common use of my freezer stash, but pizza, as a shortcut to bacon jam, and worked into any bread/roll recipe are fantastic as well.
