The Most Delicious Crustless Quiche

You can never go wrong with a tasty quiche to start off your day, and this crustless quiche made with Swiss cheese and bacon is one of my all time favorites! It’s quick to put together, flavorful, and can satisfy even the heartiest of appetites.

I’m always looking for easy breakfast recipes that my whole family will happily eat, and I’ve found that tasty quiche recipes are always a big hit! I love that you can easily customize your quiche recipe to everyone’s tastes, and it’s not too complicated to whip up. In fact, I’ve made this crustless quiche recipe three times in the past month. It’s that good.

The holidays are coming to a close, but my kids are still home from school for another week. I just baked up another quiche, so they have breakfast ready to just grab and reheat each day. They’re pretty happy it!

Crustless quiche ingredients

This delicious bacon cheese quiche is made with simple ingredients that you probably have in your kitchen. Since there’s no crust, this pie is light and packed with protein. Here’s what you’ll need:

  • Bacon. Always a favorite and it adds such delicious flavor to this quiche. You can swap the bacon for turkey bacon, Canadian bacon, diced ham or even sliced chicken sausage.
  • Cheese. The combination of Swiss cheese and bacon is so wonderful in this quiche. However, feel free to use any favorite cheese variety.
  • Eggs. You’ll need 4 large eggs for this recipe. If you can get your hands on farm fresh eggs, I highly recommend them.
  • Onion. Adds delicious savory flavor. If you don’t like onion, simply leave it out or add in another cooked veggie that you prefer.
  • Salt. Brings out all of the flavors.
  • Flour. Most quiche recipes do not have flour in the filling, but I find that it helps everything bind together and gives the quiche a lovely fluffiness.
  • Milk. You can use any milk that you have on hand: skim, 2%, whole, almond, or cashew milk.

How to make crustless quiche

Classic quiche recipes are made with a mixture of milk and eggs that gets poured into a crust, then baked. However, making a crustless quiche works great and personally, is how I prefer my quiches to be served. Here’s how to make a crustless quiche:

  1. Start this quiche by cooking the bacon, grating the cheese and sautéing the onion.
  2. Preheat your oven to 350ºF and spray a pie dish with cooking spray. Layer the bottom with cheese, then onion, and then bacon.
  3. In a blender or in a bowl with a whisk, mix the milk, eggs, flour and salt. Then pour the mixture into the dish, over the cheese, onion, and bacon layers.
  4. Bake uncovered for 45 minutes. Allow the quiche to cool for 10 minutes before slicing and serving. Enjoy!

Tips for making this easy quiche recipe

  • It’s important to pre-cook the onions and any other vegetables that you’ll be adding to your quiche, otherwise they’ll leach water if they cook in the egg mixture and they will make your quiche watery.
  • Skip the bagged pre-shredded cheese from the grocery store and grate your own Swiss cheese. The store bought shredded cheese is often coated in anti-caking agents and preservatives, and will not melt smoothly.
  • Don’t over-bake! The best quiche will jiggle a bit in the center, which means the quiche is extra creamy. Bake until the edges are set, but you still have a little wobble in the center.
  • You can use any fresh herbs you have on hand to garnish your quiche. I typically use chives, but other options include basil, parsley, green onions or dill.

Can you serve quiche cold?

Crustless quiche can be served warm, cold or at room temperature. I personally prefer to serve my quiche either warm or at room temperature, only because I think it tastes better that way. That being said, it’s simply a matter of personal preference!

Serving suggestions

If I’m enjoying quiche for breakfast, I’ll pair it with some fruit. When I make it for lunch or dinner, I usually have a small green salad on the side. I like to combine whatever fruits are in season; such as strawberries, melon, pineapple and grapes. For a green salad, simply toss mixed greens with lemon juice, olive oil, salt and pepper. Feel free to add toppings to your salad such as red onion, cherry tomatoes, avocado or croutons.

Flavor variations 

There are countless ways to customize crustless quiche to your taste preference. Here are some of my favorite flavor combinations:

  • Greek. Roasted red bell peppers, chopped cooked spinach, kalamata olives, crumbled feta cheese and minced fresh dill.
  • Mexican. Cooked and crumbled chorizo, cheddar cheese, red and green bell peppers.
  • Ham & cheese. Diced smoked ham, Swiss cheese and sautéed onions.
  • Veggie. Leave the meat out and add cooked spinach, mushrooms and any other favorite veggie.
  • Sausage. Breakfast sausage, sautéed onions, red bell peppers with cheddar cheese.

How to store, freeze & reheat this quiche recipe

Good news! Quiche is a great make ahead dish. You can store this crustless quiche either in the refrigerator for about 5 days, or in the freezer for up to 3 months.

Storing in the refrigerator.

To refrigerate the entire crustless quiche, allow it to cool completely, cover it, and store it in your refrigerator for up to 5 days. To reheat it, cover the quiche with foil and place it in the oven at 350ºF for 15-20 minutes. Alternatively, you can reheat individual servings in the toaster oven for about 10 minutes or in the microwave for about 1 minute until heated through.

Storing in the freezer.

To freeze individual slices of the crustless quiche that have cooled completely, wrap them in plastic wrap and foil, and then place them into airtight containers or ziptop bags in the freezer. To reheat, unwrap the slice and place on a microwave safe dish at 30-second intervals for about 1 minute until heated through.

If you want to freeze the entire crustless quiche, make sure it cools completely, then wrap it in plastic wrap and cover it tightly with foil. Before reheating, allow the quiche to thaw out a bit, then place it in the oven for 20-30 minutes at 350ºF until it’s heated through.
