If you got it, flaunt it. Show off your Vidalia onions as the star of the show by baking them whole and serving as a gourmet side dish. This series is sponsored by the Vidalia Onion Committee.
Baked whole Vidalia onions are a super simple side dish with a flavor reminiscent of French onion soup. And the gourmet presentation can’t be beat! Our instructions are for one onion, but you can easily bake up to six onions on the same baking sheet for an impressive dinner party spread.

Step By Step Instructions
Step #1
First, preheat your oven to 350°F. Peel your onion, leaving the root intact. If your onion sits level, you can leave it alone. If not, cut a thin slice off the root to create a flat bottom.

Step #2
Use a paring knife to cut a 1-inch deep cone into the top of the onion.

Step #3
Insert a vegetable, chicken, or beef bouillon cube into the hole. We’re using a standard-sized 4 gram bouillon cube here, not extra-large ones. You can cut large ones smaller as needed. If you’re using granulated bouillon, use 1 tablespoon. Alternatively, you can use 1 teaspoon of your favorite seasoning blend. I really like to use Italian Sausage Seasoning or Montreal Chicken Seasoning with these onions. Note that if the blend doesn’t contain salt, add 1/4 teaspoon of salt.

Step #4
Fill the rest of the hole with butter, about 1-2 tablespoons. Season with salt and pepper.

Step #5
Place the filled onion on a sheet of foil large enough to encase it. Wrap the onion in foil, bringing the edges up in the center.

Step #6
Twist the foil together to seal the onion in. Place the foil-wrapped onion on a baking sheet.

Step #7
Bake for 45-60 minutes, until the onion is tender. Serve warm.

Thanks so much, Nancy! I love how these turn out.
I’ve now made this again, using the B than B pastes in place of bouillon. Because we had seven of us, I could experiment quite a bit. Of the vegetarian pastes, the caramelized onion was the best replacement for the beef bouillon, followed by the garlic paste. The mushroom I had high hopes for, but it clashed a bit with the sweet-and-savory onion, and the vegetable paste was a little too sweet and not savory enough. I was too chicken to try the lobster paste! A mixture of tomato paste and a little soy sauce was also good. So, if you are vegetarian, don’t sleep on this recipe!
Though I have to admit, the beef bouillon is still my fave…

Thank you SO MUCH for reporting back with your experiments. I love to hear about it! I do have some of the roasted garlic paste, so maybe that’ll be what I use next time!
