How to Make Savory Roasted Onions in your Oven
Oven roasted onions with three flavors: Balsamic Vinaigrette, Butter and Parmesan or Olive Oil and Oregano. Creamy roasted onions with a mellow flavor make a perfect compliment to your next dinner. This impressive dish looks beautiful on the table and takes only minutes to prep.
Slow roasting the onions allows them to hold their shape, while the insides turn to a creamy center that is full of delicious flavor.
The natural onion flavor is enhanced by the oil and the spice you choose. I tried three variations and honestly can’t decide which I prefer.
We love onions and this has become our newest favorite way to fix and eat them!
My husband snacked on the cold leftover onions and raved about how good they were right from the fridge!

By the way, aren’t those the cutest bowls? We found them at a thrift store … for a really good price! There’s the three small ones and one large “serving” bowl. Since my husband is a sailor, he thought they were adorable and that we should bring them home.
ok, maybe that was my perspective and he just did the whole smile and nod, yes dear thing that husbands do when their wives get all excited about bowls in a thrift store.
But, I really do love them!
They’re even oven safe according to the stamp on the bottoms, so, I tested them with these onions. And sure enough, the bowls held up great.

- 4 small Onions

- Preheat oven to 350 degrees Fahrenheit.

Butter and Parmesan Oven Roasted Onions Recipe

A tip for all recipes, I found that while roasting the onions whole created a fabulous looking dish that will amaze your dinner guests, it takes a long time to bake. Slicing the onions in half creates a dish that still looks impressive. Not only do the onions bake faster, they are easier to eat.

Make it a Meal:
I served these onions as a side dish to spaghetti. They were a perfect compliment to the pasta and sauce. If you’re grilling steaks, these onions would go nicely!
Variations:
The onions I used for these recipes were a little bigger than golf balls – about an inch and a half to two inches in diameter. If you purchase smaller onions, you’ll want to shorten the baking time.
I tested these onions with a toothpick to determine when they were done. The toothpick easily pierced the onion to the center when completely baked.
You could use large onions and slice them into quarters. If you want to make a really impressing side dish, slice the onion into six sections.
Don’t slice all the way through the onion, leave about a quarter inch of onion uncut at the base. When you bake the onion, it will spread out like a flower.
