Sweet Vidalia Onion & Potato Casserole

ByElina

Around here, we love pretty much anything that gets cooked up in a casserole dish and we especially love this onion and potato casserole. It’s similar to classic scalloped potatoes or a potato gratin, but the plentiful Vidalia onions add a sweet touch that you didn’t even know was missing before. We all have a favorite way of making a creamy potato dish, but after you take one bite of this, we don’t think you’ll go back to making it the same old way again! It’s such a great combination.

1 hour 20 minutes to prepare
serves 6-8

INGREDIENTS

2 lbs waxy potatoes (like Yukon gold), peeled and sliced very thin, about 1/8 inch thick
3 sweet Vidalia onions, thinly sliced
2 cups heavy cream
1 cup mild or medium cheddar cheese, grated
1 clove garlic
1 sprig rosemary
1 sprig thyme
2 tablespoons olive oil
1 tablespoon butter, plus more for greasing dish
Kosher salt and freshly ground pepper, to taste

PREPARATION

  • Preheat oven to 375°F and liberally grease a 9×12-inch casserole dish with butter.
  • Heat olive oil and the 1 tablespoon of butter in a large pan over medium-low heat. Add onions and cook until soft and translucent, about 5-8 minutes.
  • Meanwhile, bring cream, garlic, rosemary, and thyme to a boil in a medium saucepan over medium heat, removing it from the heat as soon as it reaches a boil.
  • Arrange 1/3 of the potatoes in the prepared casserole dish, overlapping slightly. Season liberally with salt and pepper and top with half of the onions and 1/4 cup of cheese.
  • Repeat, layering another third of the potatoes, more salt and pepper, and the rest of the onions and another 1/4 cup of cheese.
  • Top with the last third of the potatoes and season with salt and pepper again.
  • Strain the cream from the saucepan to remove herb sprigs and garlic and pour liquid over potatoes.
  • Cover dish with foil and bake until potatoes are tender when pierced with a knife, about 45 minutes. Remove foil, top dish with remaining cheese and continue to bake until golden and bubbly, about 15-20 more minutes.
  • Let rest 10 minutes before serving. Enjoy!
