Reasons you will love this recipe

  • It has the perfect texture! Every bite is creamy and soft with the contrast of crispy bacon. Each forkful is perfectly rich, but has a light and delicate taste.
  • The recipe can be easily adjusted to use different types of fillings. Change up the meat and cheese, or even add sautéed veggies like broccoli or spinach.

Made this for lunch today and hopefully leftovers for a couple of days. This isn’t going to make much leftovers because my husband and I can’t stay out of it. SO good!

Ingredients needed

This delicious crustless quiche recipe is made with simple ingredients that you probably already 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 recipe. 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 breakfast. However, feel free to use any favorite cheese variety. Gruyere cheese would be delicious too!
  • Eggs. You’ll need 4 large eggs to make the filling. If you can get your hands on farm fresh eggs, we 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. Heavy cream will work fine, too.

How to make this recipe

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

Full, printable recipe at the bottom of the page.

  1. Prep. Start this crustless quiche by cooking the bacon on the stovetop until it’s nice and crispy, grate the cheese and in the same pan that you cooked the bacon sauté the onion in 2 tablespoons of reserved bacon grease.
  2. Assemble. Preheat your oven to 350ºF and spray a 9-inch pie dish with cooking spray. Layer the bottom with cheese, then onion, and then bacon.
  3. Mix milk with eggs. In a blender or in a large bowl with a whisk, mix the milk, eggs, flour and salt. Then, pour the mixture into the pie plate, over the cheese, onion, and bacon layers.
  1. Bake. Place in the oven and cook uncovered for 45 minutes. Allow the quiche to cool for 10 minutes before slicing and serving. Enjoy!

Expert tips

  • It’s important to pre-cook the onions and any other vegetables that you’ll be adding to the dish, 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 or be as flavorful.
  • Don’t over-bake! When it’s ready to remove from the oven, it 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. We typically use chives, but other options include basil, parsley, green onions or dill.

Frequently asked questions

What’s the difference between a frittata and a crustless quiche?

Frittatas and quiches are very similar! You typically think of a quiche as being baked in a crust but this isn’t always the case. Both are made with eggs, but a quiche is made with an egg custard, which also includes cream or milk. Some frittatas are made with egg whites only. Also, a quiche is baked in pie dish or tart pan, while a frittata is cooked in a skillet.

Why is quiche watery?

According to Real Simple, your quiche can become watery if you add too-wet ingredients to the filling, layering the egg custard with, for example, large slices of raw tomato or raw zucchini. These vegetables, while tasty, have a high water content when raw, which will leach into the quiche as it bakes.

Can I make this gluten free?

Yes, simply use gluten-free all-purpose flour to replace the regular all-purpose flour in the recipe.

Serving suggestions

Bacon cheese quiche can be served warm, cold or at room temperature. We like it best served either warm or at room temperature, but it’s simply a matter of personal preference!

If you’re enjoying it for breakfast, it’s great paired with some yogurt, fruit or a fruit salad. Combine whatever fruits are in season; such as strawberries, melon, pineapple and/or grapes. If you’re enjoying it for lunch or dinner, pair it with a fresh side 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, cucumber, and croutons.

Flavor variations 

There are countless ways to customize this quiche recipe to your taste preference. Here are some of our 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, asparagus and any other favorite veggie.
  • Sausage. Breakfast sausage, sautéed onions, red bell peppers with cheddar cheese.

How to store, freeze & reheat 

Good news! This 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 leftovers. To refrigerate the entire quiche, allow it to cool completely, cover it, and store it in your refrigerator for up to 5 days.
  • To reheat. Cover 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, wrap them in plastic wrap and aluminum foil, and then place them into airtight containers or zip-top bags in the freezer. To reheat from frozen, unwrap the slice and place on a microwave safe dish at 30-second intervals for about 1 minute until heated through.
  • Freezing the entire 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.
