Why You’ll Love This Spinach and Bacon Crustless Quiche Recipe
- Hearty and Satisfying: This recipe makes eight very satisfying portions.
- Can Be Made-Ahead: I like to make this at the beginning of the week and wrap and refrigerate individual portions for a quick meal.
- Flavorful and Nutritious: This quiche is not "diet food." It is loaded with bacon and cheesy goodness which just happens to also be a great low-carb meal.
Why This Recipe Works
In general, this Spinach and Bacon Crustless Quiche is a low-carb variation of the famous Quiche Lorraine but contains a thicker custard and nutritious spinach.
Quiche is a French dish consisting of a pastry shell containing a savory egg custard filled with cheese, meat, and vegetables.
A quiche in pastry will generally contain a custard of at least 4 tablespoons of milk or cream for every egg.
Since this quiche recipe does not use pastry to hold the custard, it needs a thicker custard to make a firm texture that will set and cut easily. To make a thicker custard, 2 tablespoons of heavy cream are used per egg.
This thicker custard can then hold more than its volume of cheese, meat, and veggies that you can customize to your taste. Doesn't this sound delicious? Great!
So, let's cook!
Ingredients Notes
Here's what you need:
- Softened Butter - You will need a small amount of butter or butter-flavored cooking spray to grease the pan or dish so that the quiche releases easily.
- Large Eggs - Only use large eggs for this recipe to maintain the proportion of egg to cream to 2 tablespoons of cream per egg.
- Heavy Cream - Heavy cream is preferred to keep the filling from becoming watery. Do not substitute.
- Ground Nutmeg - A small amount of ground nutmeg complements the spinach in this dish. Freshly ground is preferred.
- Crumbled Bacon - You can use freshly cooked bacon that is cooked and crumbled or finely chopped, or you can use real bacon bits from a package.
- Yellow Onion - A small amount of minced onion brings savory notes that go well with the bacon and cheese.
- Gruyere or Swiss Cheese - We like Gruyere and Swiss cheese, but you can use any shredded cheese for this quiche.
- Chopped Spinach - You don't need to use fresh spinach; you can use frozen that has been thawed, drained, and squeezed dry.
Please see the recipe card for the exact quantities.
How to Make this Spinach and Bacon Crustless Quiche
Preheat and Prepare. Preheat oven to 350°F/177°C and grease a deep-dish pie pan with butter or butter-flavored cooking spray. Place the prepared pan on a parchment-covered baking sheet.
Beat Eggs and Cream. In a large bowl beat the eggs, heavy cream, and ground nutmeg together with a hand mixer until the egg is fully incorporated with the cream.
Combine. Add the bacon, onion, chopped spinach, and shredded cheese and stir until well combined.
Bake. Pour the egg mixture into the prepared pan. Bake for 1 hour and 15 minutes or until a knife inserted into the middle of the quiche comes out clean. Cool on a wire rack for 10 minutes before cutting with a sharp knife.

My Top Tip
♡ Chop the Cheese! Shredded cheese that is chopped into smaller pieces distributes more evenly through the quiche mixture and makes a more delicious and prettier quiche. I use this same technique when making chaffles.
Substitutions & Variations
- Substitute Broccoli. You can substitute cooked broccoli that is finely chopped and thoroughly drained.
- Substitute Cheddar Cheese. You can swap out the Gruyere or Swiss cheese for cheddar cheese.
- Vegetarian. Omit the bacon to make a vegetarian crustless quiche.
- Make it Spicy. Substitute pepper jack cheese for part or all of the Gruyere/Swiss cheese.
Make-Ahead, Storage, & Reheating Instructions
- Refrigeration: After it is fully cooled, you can cover the quiche in the pan with plastic wrap, or remove it from the pan and place it in a plastic storage bag with the air pressed out. It will keep for up to 5 days refrigerated.
- Freezing: I like to cut individual portions and place them in small freezer bags. You can freeze the quiche this way for up to three weeks.
- Reheating: Gently reheat refrigerated individual portions in the microwave for 30 seconds. Then in 10-second increments until hot. If frozen, defrost the quiche before reheating.
