Most of us Washingtonians, as well as Oregonians, know of the famous Walla Walla onions that are named after their hometown, Walla Walla, Washington. Their home town even has an annual onion festival which this year will be in late June. These onions are known for their sweet taste, mild onion flavor, and their juiciness.
They have only a 3-6 week shelf life and at maturity, I am told, can weigh up to an impressive two pounds! The huge, colossal onions are great grilled on the BBQ, sliced and used in hamburgers, sandwiches or salads. At the beginning of the season they are much smaller and resemble a giant scallion.
Recently, I spotted some very large scallion-type onions in my favorite produce market, I didn’t pay enough attention to them to even check the label to see what exactly they were.
I did note that they were definitely not leeks. It was only a few days later that our son, Burl, mentioned in conversation that the family had visited friends in Eastern Washington and they had served baby sweet Walla Walla onions grilled on the BBQ. He was very impressed with their flavor and sweetness. It occurred to me that that was what I had spotted in the produce market.
I made a special trip back to the market and bought a couple bunches of these little sweeties. When I roasted them they really did taste sweet, juicy and delicious. I also made a wonderful Onions and Tomato Quiche.
If you have never tasted these baby onions I hope you have a chance to buy some while they are in season. The onion season is short and will run from June through August. Happy grilling!

Notes

Yum, Pat! These look great. I”m not sure if I can find them in my area, but I’m going to look. I love any veggie on the grill.
Oh, yes, I am sure you will like these on the grill. Later in the summer the big daddy’s should be in the stores, some of them can get as large as 2 pounds! I’m watching for them as I think they will taste great thick sliced and grilled. thanks for your comments. I hope you find some of these onions. 🙂
I don’t believe I’ve ever had a Walla Walla onion. I have to look for them, particularly since I so love the name! 😉 Good stuff — thanks.
I hope you can find some, John, the season only runs from June to September. I am waiting for some of the huge 2-pounder’s so I can grill them up. thanks for the comments. 🙂
You know I love these, being a local Washingtonian! I have never grilled them or even thought of grilling them – so clever!
