Yay for quiche all the time! Quiche is a flexible dish for sure and certainly one that anyone can learn to make like a champ. I do appreciate that not only is quiche perfect for serving at any meal time, but there are endless ingredient combinations to please all palates.

I find this Sautéed Onion Gruyere Spinach Quiche Recipe a particularly pleasing combination. Packed with fresh baby spinach leaves, sautéed onions, creamy gruyere cheese and thyme, how could it not be?

Sautéed Onion Gruyere Spinach Quiche is a fantastic meatless option too! Of course a handful of crumbled bacon could easily be added for all of those bacon lovers out there. When entertaining, consider preparing one with bacon and one without to please all of the quiche eaters.

If you’ve never made quiche before, it’s as easy a pie, because, well, it is a pie, a deliciously satisfying savory pie. Begin by fitting a 9-inch pie dish with pie dough and bake for about 25 minutes until lightly browned. While the pie crust is baking, saute onions for a few minutes. Next add spinach, salt pepper and thyme and cooked for a couple of minutes until the spinach is slightly wilted. Finally beat the milk and eggs together. Stir in the cheese, along with the onion, spinach, herb mixture. Allow the pie crust to cool slightly once it has finished baking, then pour in the egg mixture. Bake until set. It usually takes about 30-35 minutes depending on your oven. It will be slightly jiggly in the middle when ready. Let cool slightly before serving.

This quiche rewarms well so it could be prepared a day ahead, then rewarmed. Another option is to prepare the filling up to a day ahead, then cover and refrigerate until ready to assemble.

Quiche couldn’t be easier and I find it an excellent dish for serving throughout the year, any time of the day. This one is particularly nice for brunch or a light lunch, and it is oh so perfect for holiday entertaining. Whatever time of day you decide to serve quiche, I sure hope you enjoy this one as much as we do!

Sautéed Onion Gruyere Spinach Quiche Recipe

Packed with fresh baby spinach leaves, sautéed onions, creamy gruyere cheese and thyme, this delicious quiche is perfect for any time of the day.

Ingredients:

  • 1 (9-inch) unbaked pie crust
  • 2 tablespoons extra virgin olive oil
  • 1/2 cup thinly sliced sweet onion
  • 3 cups (packed) fresh baby spinach leaves
  • 1/4 teaspoon salt*
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon dried thyme leaves (NOT ground thyme)
  • 1 cup milk
  • 3 large eggs
  • 3 ounces Gruyere cheese, grated**

Directions:

  1. Preheat oven to 350-degrees F.
  2. Bake 9-inch pie crust until slightly browned, about 25 minutes. Set aside to cool.
  3. Heat a large skillet over medium-high heat. Add oil to coat. When oil ripples, add sliced onion and saute for 5 minutes. Add spinach, salt, pepper and thyme; cook stirring for another 2 minutes.
  4. In a mixing bowl, thoroughly whisk together milk and eggs. Stir in shredded cheese, as well as onion/spinach/herb mixture.
  5. Pour egg filling into prepared pie crust. Bake at 350-degrees F for 30-35 minutes. Let cool slightly before serving.

*I reduced the salt for this quiche since gruyere tends to be a bit saltier than some other cheeses. If using another cheese, add a pinch or two more of slat if you’d like, but don’t overdo it.

**Gouda or Havarti would be nice substitutions.
