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.

Perfect recipe for baked vidalia onions!! So good!! Melty delicious goodness!!
Debra, I’m delighted you liked it so much. Thanks for coming back to let me know 🙂
Have tried this and it is wonderful! Thank you so much for this!
You’re welcome, Sarah! I’m so glad you loved it.
Baked Vidalias are delicious!
I agree, Deborah! Glad you loved it.
Will a sweet yellow onion work with this recipe?
Yes, any sweet onion will work here, it’s just extra delicious with those Vidalia onions. But when they aren’t available, a sweet yellow onion is perfect. Enjoy, Renette!
I make these all the time. I have to bake them at 425 for about an hour and a half for them to be completely tender. 350 would probably take about 3 hours
I love this recipe! This is now my base recipe and I change it up depending on what I’m pairing it with and what I’m in the mood for.
Today I’m adding a teaspoon (give or take) of Worcestershire sauce and more fresh cracked pepper.
I’ve also packed them with brown sugar, topped with butter and sprinkled salt and red pepper on top. Sweet hot! 👍🏼
Oh, I love those ideas, Janeece! Thanks for taking the time to share them with us.
Sounds great! I will try this!
I hope you love it, Debra!
Great!
Thank you, Adriene!
So good and easy, everyone loved them
So happy to hear that, Carolann!
Been doing something similar, since the 1970’s, but instead of a bullion cube, I use brandy. Taught to me by the Chef in a now defunct Basque restaurant in the central valley of California. After reading your version, I combine the brandy with beef Better than Bullion. Wow!
Interesting, thanks for sharing, Gary!
Soooooo delicious. Open the onion into a bowl because there’s going to be a lot of broth. If you like French onion soup, you’re going to like this! . Save one for the next day, melt cheese on it for lunch!
Thank you so much, I love these onions too!
Dipping sauce?
Donna, the onion ends up quite soft with this recipe and isn’t really dippable. But if you wanted to, you could have some ranch dressing or ranch dip on the side.
What a great recipe for Vidalia onions! Absolutely delicious! Wish my grandmother was here to try this recipe, she would adore it; she was a chef.
Thank you so much, Rick! I’m glad you enjoyed it and that it made you think of your grandmother.
I haven’t made this yet but plan to for dinner tonight. Just wondering, how much Better Than Bullion would you suggest? Also, I love the idea of topping it with cheese. Just might try some pepper jack (I love spicy!)
You want about 1 teaspoon of better than bouillon in place of one cube. Enjoy, Mimi!
I have made this multiple times, it’s always a hit.
Love to hear that, Margaret!!
Love these! After they were done baking, I opened the top of the cone, added provolone cheese and put under broiler. A different side dish that goes with anything! Inexpensive and Amazing!! Thank you for this recipe!
Yum! That sounds wonderful, Cindy.
