"Doomsday" jerk marinated roasted onions

Sharing is caring!

There are some recipes that are so easy to make yet so delicious you keep them in heat rotation, likely weekly. For us these jerk marinated roasted onions qualify.

Thick cut onion slices are marinated in a wet jerk seasoning mix and then slow-roasted to deliciousness.

This roasted onions recipe was stolen from the mental vault of the great chef and my grandfather, Mr. James Napoleon Brown. He loved onions, particularly raw onions -green, red, white, yellow it didn't matter. This love for and daily consumption of raw onions was a doomsday scenario for my brother and me as invariably his frequent yelling for us to look at him when he spoke to us forcing us to smell the onion infused halitosis while straining simultaneously to lift our eyes up to make contact with his.

Texturally, the interior is soft and creamy, with the edges slightly crispy. I used a mild Jerk marinade as I wanted a more mellow flavor that enhanced and complimented the sweet onions. If you prefer more heat know that the stronger the marinade then the more of that flavor is impaired on the onions. In other words a little goes a long way, so reduced the amount of heat you use.

  • Fresh Thyme Leaves
  • Kosher Salt
  • Black Pepper

How To Roast Onions (step by step)

Over the years I've made a version of marinated smoked or roasted onions. I often lament the fact that my grandfather, never wrote anything down. Luckily with this dish, you don't really need one. It's as simple as slicing onions, dropping them in your preferred marinated overnight, and then slow roasting them for an hour or so. The flavors in these are intense. The natural sweetness in the yellow onions is concentrated as the onions caramelize in the jerk marinade during roasting.

Step 1: Marinate the onions

Cooking Tips for Jerk Marinated Oven Roasted Onions

  • If using small onions just slice them in half, otherwise for larger ones just slice them in thirds crossways so all of the slices roast evenly.
  • Leave the skin on as they will help keep the onions intact when cooking.
  • Keep the marinade as simple or complicated as you prefer
