Slow Cooker Caramelized Onions

It’s “Caramelized Onion” week in our house…so the first recipe to make would, of course, be Slow Cooker Caramelized Onions!

My daughter LOVES caramelized onions, and she’s constantly giving me ideas of what to make with them.

Well, friends…this week her dreams are coming true.

I will update this post with links to following recipes that I plan to make this week.

So far I have planned:

Caramelized Onion and Steak Flatbreads

Goat Cheese Caramelized Onion Pasta with Bacon

Caramelized Onion and Gruyere Cheese Dip

And Cheesy Caramelized Onion Pig Shots

You can also freeze these onions for a few months.

So even if you’re not crazy like me and making EVERYTHING in a week with these, still make the whole batch and freeze them.

How to Make Slow Cooker Caramelized Onions

This may seem like a lot of onions, but they reduce in size so much that really at the end you have about 6 cups of caramelized onions.

So yes, we are going to peel and thinly slice EIGHT yellow onions 🙂

If your eyes are sensitive, get some goggles or safety glasses.

Honestly if you have a super sharp knife the cutting should be pretty painless.

And yellow onions are fairly mild.

I like to cut the ends off and peel them, then cut in half to have a flat surface on the cutting board.

Then thinly slice, again a good quality knife helps so much.

Once the onions are cut, transfer them to the crock pot/ slow cooker.

Next set out some brown sugar, balsamic vinegar, butter, kosher salt, pepper, and crushed red pepper flakes.

Add 1/3 cup each of the brown sugar and balsamic vinegar.

Cut 4 Tablespoons butter into smaller pieces and add those in too.

Then season with kosher salt, pepper, and crushed red pepper flakes.

Turn the slow cooker on low for 8 to 10 hours, stirring a few times throughout.

This is what you’ll see about halfway through cooking.

Keep letting it go a few more hours, and keep stirring.

It’s kinda cool seeing the process of caramelizing each time you stir.

THIS…this right here my friends is what you want to see!

Gorgeous golden brown, practically falling apart.
