The Great Walla-Walla Onion Pie Escapade
So, there I was, staring down four sweet onions, a tablespoon of olive oil, three tablespoons butter, two eggs, and a sprinkle of nutmeg, among other things, wondering what in the world I’d gotten myself into. This wasn’t your average, run-of-the-mill culinary endeavor. No, this was the Walla-Walla Onion Pie challenge.
The Unassuming Pie Crust
We all know the crust is the unsung hero of any pie, so let’s not overlook it here. The first step was to prepare and partially bake a crust to fit a 9-inch pie pan. Sounds simple, right? Well, if you’ve ever wrestled with pie dough, you know it can be as stubborn as a mule with a grudge. But a few gentle reminders from my rolling pin, and lo and behold, I had a crust in the oven.
The Sweet Onion Tango
Next up, it was time to get down and dirty with those sweet onions. Now, if you’ve never had the pleasure of thinly slicing four onions, let me tell you, it’s an experience. I’m not saying I cried, but there may have been some gentle weeping. Once my eyes had recovered, I sautéed those onions in a delightful mix of olive oil and butter until they were golden yellow and my kitchen smelled like an Italian grandmother’s house.
The Egg and Cheese Rendezvous
With the onions doing their thing, I turned to the eggs, half and half, flour, salt, pepper, and nutmeg. It was like a high school reunion in my mixing bowl. I beat them together, then added in the onions and half of the Swiss cheese. Honestly, I couldn’t tell if it was a pie filling or a savory custard. But who am I to question the process?
The Grand Finale
The moment of truth was upon us. I poured the oniony, eggy, cheesy concoction into the crust and sprinkled the remaining cheese on top. Then, into the oven it went for 25 to 30 minutes. Let me tell you, waiting for that pie to bake was like waiting for paint to dry on a roller coaster. Exciting, but nerve-wracking.
The Verdict
Out of the oven came a golden brown, bubbling marvel. A sprinkle of chopped parsley on top, and it was a sight to behold. But, the true test was in the tasting. Spoiler alert, it was delicious. The sweetness of the onions, the richness of the eggs, the creaminess of the cheese, and that little kick from the nutmeg. It was like a symphony in my mouth.
So, there you have it, folks. My Walla-Walla Onion Pie escapade. And let me tell you, it was worth every tear shed over those onions. Because, in the end, isn’t that what cooking is all about? A few laughs, a few tears, and a whole lot of deliciousness.
