    Quiche has always beckoned a leisurely weekend pace for me, and this Keto Crustless Quiche with Bacon is my idea of brunch perfection. I like to make and enjoy it on the weekend, and then have leftovers to enjoy throughout the busy week. Give it a try, and I think you will agree, it is the perfect way to power your morning.

    The first time I had quiche was at a cute local brunch spot. It was served with a crisp green salad, and it was love at first bite.

    Of course, it had a crust, making it unsuitable for my current low carb and keto lifestyle.

    This Keto Crustless Quiche is every bit as delicious as the original, and since you don't have to mess with rolling out a crust, it is super simple to make.

    This easy keto recipe is perfect for breakfast or brunch!

    For a special brunch, I like to serve it with a simple green salad with poppy seed dressing and Keto Cheese Breadsticks. Other good options are Fathead Bagels, Keto Waffles, or Blueberry Muffins.

    Ingredients for Making Crustless Quiche Keto

    • Bacon: You can use any bacon that you like, but do make sure you check the label. Many brands have sugar which can impact the carb count.
    • Onion: I used a yellow onion, but white or red onion would also work.
    • Thyme: I used dried thyme, but if you happen to have fresh thyme on hand, that will work as well.
    • Cayenne Pepper:  This adds a subtle kick of heat. If you don't care for heat, feel free to omit.
    • Shredded Cheese:  I recommend shredding your cheese to avoid unnecessary additives.
    • Eggs:  I always use large eggs, but whatever you happen to have on hand will work here.
    • Heavy Cream:  I love the richness this adds to the crustless keto quiche. If you are low-carb and not keto, half and half would work.  
    • Salt: Adjust the amount of salt to your liking.

    Tips & Tricks

    • I recommend cutting the bacon into strips about ¼ to ½ inch wide. This adds a wonderful texture that you don't get with smaller pieces.
    • Remove the quiche from the oven when it is just set. It can get rubbery if you cook it too long. And remember, your quiche will continue setting as it cools.
    • Speaking of cooling, don't skip letting your quiche cool! I recommend allowing the custard to firm up for 40 minutes or so. If you have the time and want the best looking slices, chill it before cutting and reheat the individual slices. You don't want to slice it while it is hot!

    How to Make Keto Crustless Quiche

    Start by preheating your oven.

    Next, heat a skillet to medium. Add your bacon and cook for three minutes.

    Add the onion, and cook for about 7 more minutes, or until the bacon is crispy. The exact time will vary based on your bacon type (pork, beef, turkey) and thickness.

    Remove from the skillet with a slotted spoon and transfer to a well-greased pie plate.

    Sprinkle with the thyme and cayenne pepper and top with the cheddar.

    Whisk the eggs, cream, and salt in a large bowl.

    Pour the eggs over the bacon, onion, and cheddar.

    Bake until set, about 40 minutes.

    Notes

    Storage

    Refrigerator Storage

    You can store this keto quiche covered or in an airtight container in the refrigerator for up to four days.

    Freezing 

    You can freeze this quiche for up to three months. If you are freezing a cooked quiche, I recommend cutting it and freezing in individual portions, for an easy meal without a lot of planning.
    Is it better to freeze quiche cooked or uncooked?
    I find that it is easier to freeze the quiche once it has been cooked, since I don't have to worry about spilling on my way to the freezer. Also, I love the convenience of having frozen portions of it that I can pull out and let defrost overnight in the refrigerator when I know my time is going to be tight the next morning.
    If you want to freeze an uncooked crustless keto quiche, you can! Just wrap it tightly in freezer paper and foil.
    Either way, I recommend thawing overnight in the refrigerator before enjoying.

    Reheating

    Reheating quiche isn't necessary - it is delicious straight from the fridge!  
    If you want to enjoy it warm, it is easy to reheat.
    I prefer the taste when I reheat quiche in the oven. To do this, you can cover it in foil and cook in a 350° F oven until it is heated through, about 15 to 20 minutes.
    If you prefer, you can also reheat it in the microwave.
    Make Ahead
    You can make this the night before and keep it covered in the refrigerator. Just be careful when you are transporting the quiche from the fridge. I find it easier to prep all of the components and then put them together at the last minute.

      I love quiche but was unsure of one with no crust. This recipe is fantastic. Just a bit of heat from the spices that makes it interesting. This recipe is a keeper. Thanks
