3 Easy Ways to Caramelize Onions

Caramelized onions,

onion pieces cooked low and slow in a skillet with butter and olive oil

are part of many recipes

because they add a wonderful layer of flavor

The downside of caramelized onions

is that they take 20-30 minutes to make

and you have to stir them every 2-3 minutes

Since Patience is not my middle name,

and I’ve found 3 ways to make this step easy peasy

so you can focus on making your recipe

Method #1, Foil

Slice onion/onions

Stack slices on a square of foil with a pat of butter,

a drizzle of Olive oil, S & P

Bring sides up to form tight packets

Roast at 400 for 1 hour

Cut slices in smaller pieces or whatever the recipe calls for

These baked onions don’t have any darker areas,

but they do have tons of flavor

Method #2, Sheet Pan

Another short cut way to make caramelized onions

is on a sheet pan in the oven

Drizzle them with olive oil, salt and pepper,

toss to coat and spread them out into an even layer

Give them a sprinkle of water

which helps them steam and soften

These take about the same time as cooking them in a skillet

but you don’t have to stand there for 30 minutes stirring them!

Remove from the oven when they are brown

and beginning to char, 30-40 minutes

Even though mine look a little burnt

they had incredible flavor and didn’t taste burnt at all

Method #3, Slow Cooker

These slow cooker onions take 14 hours so plan ahead!

Put the sliced onions into the slow cooker with butter and olive oil

Season with salt and pepper

I started them in the afternoon,  and let them cook all night

In the morning they were golden and creamy

and the house was full of a magical aroma

Store them in the refrigerator for up to 10 days

and use them as needed
