Grilled Whole Onion in Foil

Grilled French Onion

It doesn’t get much easier than this for a tasty side dish.

This idea was inspired by my cousin, Scott, who first told me about this basic grilled treat.  Scott and his dad, my uncle Bill, are both excellent cooks.  I look forward to every meal they prepare.

So, how easy is this:  Onion, beef bouillon cube, butter, salt & pepper.  Wrap, grill, eat.

 Onion with seasonings


Doesn’t get too much easier, right?  Apparently this is also a hit with campers and hunters out there, looking for a tasty easy dish to eat or throw on top of…well…everything.

Core the onion with a knife

So, you just take a whole yellow or vadalia onion and core out the middle with a knife.

Place the seasonings into the cored onion

Then set it on tin foil, add the buillon cube and butter to the cored out hole, then sprinkle salt & pepper all over.  Wrap the onion up tight and cook it for as long as you would like – the longer it cooks, the sweeter and softer the onion gets.

I cooked mine for about an hour while doing a beer can chicken.

If you love onions as much as I do, throw this sucker on next time you fire up your grill.  When you take your first bite, tell me it doesn’t taste exactly like French Onion Soup.  You can’t.  If you said it didn’t, you’d be lying.

Finished Grilled Onion

And no one likes a liar.  Enjoy.
