Recipe Tips and Tricks

  • Use fresh herbs. You can often substitute dried rosemary when making recipes, but for oven roasted onions, fresh sprigs make all the difference. Be sure to remove the stems and chop the leaves to help release their flavor and aroma!
  • Tip to avoid teary eyes: There have been numerous tricks shared throughout the years, from wearing goggles to slicing near running water.

    The newest tip for cutting onions is to hold a chunk of bread or a cracker in your mouth, letting it hang out as you chop. I can’t guarantee it will work, but it’s worth a try!
  • Get your hands dirty! I’ve tried using spoons to toss the dressing with the vegetables, but hands really are the best tool for the job.

How To Cut An Onion Into Wedges

First, trim both the root and stem sides of the onion. You’ll often see dried brown roots on one side — slice off enough to remove these, but leave the thick white nub intact. This prevents the layers from separating.

Remove the peel and the outer layer (or two) if it appears dented or damaged. Slice in half through the stem, then in half again to make quarters.

Kitchen Tools You Will Need

  • Rimmed Baking Sheet - Used for anything from cookies to roasting, a good baking pan will last for years.

  • Quality Knives and a big solid Cutting Board make prepping a breeze and are well worth the investment.

  • Citrus Juicer - This gets every last drop out, which makes juicing lemons so much easier.

Roasted Onions FAQ

What goes well with roasted onions?

This easy recipe pairs wonderfully with meat and poultry dishes. Enjoy with a simple weeknight dinner or add it to your holiday menu, doubling as needed for extra guests.

It’s especially delicious alongside a beef roast, pork tenderloin, or any main course that could use a tangy and sweet side dish.

Which onion is best for roasting?

The general rule for onion varieties is this: red is best raw, white is used to flavor dishes, and yellow is the most versatile for cooking.

That said, there are always exceptions to the rule! When paired with herbs like rosemary or parsley, the sharp red onion can be cooked to caramelized perfection.

What can I do with a bunch of onions?

Make these baked onions, of course! If you need to use them quickly, dice and freeze them to toss into skillets and sauces. Or, make a pint’s worth of caramelized slices in the crockpot.

  1. I love onions, too and this looks wonderful. The dressing by itself sounds great. One of my daughters just decided that onions that are cooked are actually pretty good, but the other one won't touch them. This is a great side dish - love it!

  3. Oooh, yum! I've never thought about serving onions on the side - am wondering how that would go over here at the 365 house.
    Definitely worth trying. Thanks, Donna!

  4. I love this combination of flavors. I can't imagine just doing onions though. I usually roast other veggies or potatoes with them. Sam would be in heaven with just a pan of onions though. I'll have to try onions on their own, now that I have four million pounds of them here to use!
