recipe | olive oil potato gratin
Here's a secret. I'm not all that patient when it comes to cooking. I burn things a lot. I like to blame it on the fact that most evenings I'm cooking while tripping over a tiny toddler who likes to pull all the pots and colanders out of the cupboards and onto the floor before opening the refrigerator door over and over while saying, "hmm, thupperrr." I also like to blame my inadequacies on my gas stove, because it never seems to get low enough. Simmering is not an option. It's low boil, or boil over. Nothing in between. But, no, the truth is that I'm just not patient enough. I don't like to stand at the stove and wait, and flip, and test, and wait some more. Ryan, my dear husband, has unmatched diligence in the kitchen, which is why he is in charge of cooking any expensive cuts of meat we happen to have. He's also the boss of making bacon at our house, and working pizza dough into the most perfect circular shape. I can throw together a mean soup without messing anything up, and lasagna is totally my jam, But you don't want me caramelizing your onions or anything.
Except I really love caramelized onions.
Which brings me to this: Olive Oil and Potato Gratin. It's an easy yet hearty side dish, with just a few simple ingredients. Not super rich or creamy or cheesy like most potato gratins, but it'll warm your toes just right. The hardest part is standing by the stove and stirring those onions into sticky, garlicky sweetness for 15 minutes while your child pulls all the cucumbers out of the fridge drawer and rolls them across the floor. And then empties your purse till he finds the tic tacs. At least, that's how it was at my house yesterday. I did not burn the onions though. Progress!
And now, the recipe, changed ever so slightly from the America's Test Kitchen version. I served ours last night with a roasted chicken stuffed with onion and lemon, and some steamed peas (Ralphie's fave.)
Olive Oil and Potato Gratin
1 cup grated Parmesan cheese
1/2 cup panko bread crumbs
2 onions, halved and sliced thin
2 cloves of garlic, minced
1 teaspoon minced fresh thyme
1 cup chicken broth
3 pounds Yukon Gold potatoes, peeled and sliced 1/4 inch thick
salt and pepper
1. Preheat oven to 400 degrees. Grease a 9x13 baking dish.* Combine Parmesan, 3 tablespoons olive oil, panko bread cumbs, and 1/2 teaspoon pepper. Set aside.
2. Heat 2 tablespoons oil in a skillet until shimmering. Add onions, 1/2 teaspoon of salt, and 1/4 teaspoon pepper and cook, stirring frequently, until browned (about 15 minutes.) Add garlic and 1/2 teaspoon thyme and cook until fragrant, about 30 seconds. Add 1/4 cup broth and cook until nearly evaporated, scraping up any browned bits. Remove from heat and set aside.
3. Toss potatoes, remaining 3 tablespoons oil, 1 teaspoon salt, 1/2 teaspoon pepper, and remaining 1/2 teaspoon thyme together in a bowl. Arrange half of the potatoes in prepared dish, spread onion mixture in even later over potatoes, and arrange remaining potatoes over onions. Pour 3/4 cup broth over potatoes. Cover dish tightly with aluminum foil and bake for 1 hour.
4. Remove foil, top gratin with reserved Parmesan mixture, and continue to bake until top is golden brown and the potatoes are completely tender, about 15 minutes. Let cool for 15 minutes. Serve.
*It should be noted that instead of a 9x13 baking dish, I used 4 small individual baking dishes (a fun Christmas gift from my sister, purchased here.) and an 8x8 baking dish. I reduced the baking time a smidge, but otherwise followed these directions.
