Caramelized Onion and Bacon Quiche

Quiche in a tart pan.

Rich and creamy Quiche with sweet caramelized onions and salty bacon is perfect for your next brunch or luncheon. Nothing wrong with eating one for breakfast or dinner too. I always associate quiche with Spring and Easter and if you’re serving Easter Brunch at home, a quiche is a welcome addition. It has a wide appeal and can be made in advance. Serve it warm or cold.

Quiche in a tart pan.Be patient when caramelizing the onions and be sure to slice them thinly and evenly. The heat should be fairly low so they develop a deep caramel color without burning. I like to save a little bacon grease when I cook the bacon and add it to the pan when sauteing the onions so they pick up the bacony flavor.

Many different types of cheese work well in a quiche and you can even do a mixture of different types to use up what you have in your refrigerator. I have used a mixture of Gruyere and Cheddar, but any type of Swiss works well as well as Monterey Jack, Jarlsberg, smoked Gouda, or Fontina.


This Caramelized Onion and Bacon Quiche recipe is the only quiche recipe I’ve seen that calls for stacking 2 refrigerated pie crusts. If you think the pie crust is the best part of the quiche, you will like this. Or if you’re like me and you use one pie crust out of the box and the other lingers at the back of the fridge until it’s too old to use, using them both at once will prevent waste.

Caramelized Onion and Bacon Quiche



  • 1 package refrigerated piecrusts
  • 2 large sweet onions, thinly sliced
  • 1 tablespoon olive oil
  • 1 tablespoon butter
  • 1 teaspoon bacon grease, optional
  • 6 cooked bacon slices, crumbled
  • 1 1/2 cups shredded Gruyere cheese
  • 1/2 cup shredded sharp Cheddar cheese
  • 1 1/2 cups half-and-half
  • 4 large eggs
  • 1/2 teaspoon salt
  • 1/4 teaspoon freshly ground black pepper
  • 1/4 teaspoon nutmeg


  • Preheat oven to 425 degrees. Unroll pie crusts and stack on a lightly greased surface. Roll into at least a 12-inch circle, depending upon the size of your pan. Mold pie crust into a deep dish pie pan or 10-inch deep dish tart pan with removable bottom. Trim off excess pie crust along edges. Place a sheet of aluminum foil or parchment paper on pie crust and place pie weights or dried beans on top. Place on a foil-lined baking sheet and bake for 10 minutes. Remove weights and foil and bake an additional 8 minutes. Cool completely, about 15 minutes.
  • Reduce oven temperature to 350 degrees.
  • While piecrust is baking, cook onions in olive oil, butter, and bacon grease in a large skillet over medium-low heat. Stir often and cook for 15 to 20 minutes, until caramel colored. Remove from heat and add bacon crumbles to pan with onions.
  • Place half of onion-bacon mixture in piecrust and top with half of cheese. Repeat with remaining onions and cheese.
  • In a medium bowl, whisk together half-and-half, eggs, salt, pepper, and nutmeg. Pour over cheese.
  • Bake for 40 to 45 minutes at 350 degrees, or until set. Cool 15 minutes before serving.

  1. We have an abundance of eggs from our chickens at times. I have tried my hand at several different quiche recipes. This one is amazing!

  2. This was delicious!!! Doctored it a little bit based on some comments (added an extra egg). I also caramelized the onions for much longer than 20 minutes. Took about 45 to 50 minutes but well worth the patience. The onions turned out absolutely delicious. The result of your recipe overall was flavorful and delicious! Thank you – cannot wait to make this one again and hopefully will figure out how to keep the edges of the dough higher around the edges 🙂

  3. Question: How do you keep your pie crust from sinking down around the sides? Ours shrunk down about half way which made it difficult to make “deep dish” style?

      Try fitting the crust in the pie pan and then sticking it in the refrigerator for 15 to 20 minutes or the freezer for 5 minutes.


    shouldn’t the bacon be cooked to fry stage
    should onions be sliced half moon
    Instructions aren’t very complete

  5. This quiche needs more egg or less onion or something. It took way longer than 40min to cook and doesn’t have a quiche texture… too much filling, not enough egg in between.

  6. I was so happy to find a recipe that didn’t require heavy cream. To be on the safe side I used 3/4 of half-and-half and 1/4 of heavy cream. Since I had some leftover cooked Swiss chard I added about a half cup of that I used 4 bacon pieces instead of six. It was absolutely wonderful! This recipe is a keeper!

  7. I rarely cook, so I am thrilled to find a recipe I can understand, and get the great nutrition from eggs and cheese.
