Vidalia Onion Casserole

Hi Everyone! Welcome Back to Turnips 2 Tangerines. Today I’m going to share with you an updated version of sorts, of a recipe I posted a few years back. I found the recipe on the Vidalia Onion website and it’s one of T2T most popular recipes. The recipe has since been taken off the website, for reasons unbeknownst to me. With that being said, I wanted to share with you a new and possibly updated version of this super delicious and classic recipe. Vidalia Onion Casserole is made of course with Vidalia onion, grown in Vidalia GA. This recipe also contains Ritz crackers. I love a good Ritz cracker crumb topping! Not only are the Ritz crackers made into that yummy cracker crumb topping that I love but crushed Ritz crackers are added to the filling! What more can I say?!?

Onions Never Tasted So Good!

There are a few steps to this recipe but nothing that is time consuming or daunting. Thinly slicing the Vidalia onions and boiling them in water for 8 minutes will ensure that the onions become soft and tender. Tossing the warm, drained onions with butter doesn’t hurt either. Evaporated milk ensures the sauce will be smooth and rich. We opted for using a “seriously” sharp white cheddar cheese by Cabot Creamery. A Vermont cheese company that has been in the business of making cheeses and other dairy products since 1919.

We certainly can’t mention Vidalia onion casserole without mentioning, Ritz crackers. You know the one…those buttery round crackers everyone knows and loves. You can also use Townhouse buttery crackers but for heavens sake, don’t substitute anything else. No off brand or store brand buttery crackers will do here. They just don’t taste the same and I should know I’ve tried it! Some things can and should be substituted for a cheaper brand but in my humble culinary opinion…not buttery crackers! (creamed canned soup is another that comes to mind)

Serve Only or As a Side

One thing that I really like about this casserole is the fact that you can either serve it as a side dish or on it’s own. Personally I like to serve Vidalia Onion Casserole with grilled burger or steak, a suggestion that someone once thought of as “odd.” My hubby on the other hand likes to reheat a serving of onion casserole in the morning, plop an over easy egg on top and call it a day or “new way with left0vers.” One thing that should be mentioned is the fact that Vidalia Onion Casserole is about as economical as all get out! The next time you’re invited to a gathering, consider bringing this super easy and delicious casserole. You might be surprised how many people like it!
