Brown Your French Onion Meatballs First

It’s all about texture. Because the meatballs are cooked in stock they will have a softer texture. If you want your meatballs to be a little crispy, you can brown them in the pan before caramelizing your onion.

Simply add a tablespoon of butter to your pan, add in your meatballs and over medium heat let them brown up, it should only take a few minutes. Once browned, scoop them on a plate and set aside. Then follow the recipe below.

My favorite meatballs. If you’re a long time reader, this is of no surprise. If you’re new here, I have two favorite meatballs. I love my homemade meatball recipe but I also know that weeknight dinners need to be kept simple and easy, and sometimes making homemade meatballs is not ideal for meatball recipes…. so my favorite grocery store meatball are the Cooked Perfectly brand. They have so many options like organic, gluten-free, turkey, hidden vegetables, etc. and they come is many different flavors and sizes. For this recipe I used the Homestyle Bite Size.

I discovered this Cooked Perfectly brand in 2020 when we rented a beach house while we took on a change of scenery during stay-at-home COVID time. Since we were on vacation with a newborn and two toddlers, we opted in for frozen already cooked meatballs and once the groceries were delivered, I was hooked. It’s truly a favorite brand, this is not an ad or paid sponsorship.

How to Caramelize your Onions Step-by-Step

Caramelizing onions can be a bit intimidating but once you follow these step-by-step instructions, you’re see that it can be done easily, you just have to trust the process and let them sit without stirring.

Fun fact: Onions are full of water, they do not require butter or olive oil like other vegetables because they sweat out their liquid so easily, a lot of recipes, this one included, uses butter because butter adds flavor.

When you cook an onion you can see it go through many different stages. When you add a thinly sliced onion to a pan and place it over medium low heat, you can watch it go from being hard with a pungent raw smell to soft and translucent, then finally to caramelize brown with a sweet smell, all you need is time. If you do this too quickly over high heat, the onion will not cook throughly and risk the danger of burning.

The take-away, use medium low heat and patience. Stir minimally. When the onions cook on the stove top, you can grate the cheese or load the dishwasher.

Times will vary – this is based on the recipe below (5 small onions), it took 20 minutes for a low caramelization, building the foundation for that French Onion flavor.

As you can see the bottom of the pan has browning, that is okay, and will happen if you use a stainless steel pan, you will not see this in a non-stick pan. Once you add the wine and beef stock from the recipe the bottom bits will come up and will be incorporated back into the rich cozy flavors of these French onion meatballs.

Here are some of my favorite recipes that call for caramelized onion. French Onion Soup, French Onion Soup Pizza, and this Grilled Cheese!
