So grab your pie pan, and let’s get crustless quiche makin’ friends!
What is Crustless Quiche?
Crustless quiche is exactly what it sounds like — the delicious, cheesy, meaty quiche filling, without the crust! While means less carbs, less work, and more of the good stuff.
The one important note to make about crustless quiche, is that you can’t use a tart or quiche pan to make it — the bottom of traditional quiche pans aren’t attached, and this quiche has no crust to hold the ingredients together. So save yourself a giant mess and use a pie pan or casserole dish when baking this quiche!
Since I stick to low carb recipes, I used heavy cream in this quiche. If low carb isn’t your goal, swap this for regular milk!
Crustless Quiche Recipes Swaps
Crustless quiche recipes are rather flexible. Just keep the quantity of cheese, cream, and eggs the same, and mix and match your favorite meat and low carb vegetables.
I often start with a basic crustless quiche recipe (eggs, cream, salt, pepper and cheese) and toss in some leftovers for a quick crustless quiche — chicken, steak or sausage are amazing! Keep the amount of protein you use around the same as the pancetta in this quiche, and be sure to cook it completely before adding.
Add keto vegetables of choice, keeping the amount of veggies used the same as what’s in the recipe. Again, be sure to cook your veggies before adding them the the pie pan — this helps to release any liquid they contain so your quiche will bake properly.
Although it may not seem like it, a crustless quiche broccoli, spinach or mushroom would be ruined by the amount of liquid veggies contain.
This quiche recipe is a magical combination of the low carb foods my family loves most — here are some other variations you may prefer:
Crustless Quiche Lorraine
Swap pancetta for bacon, mozzarella for swiss, leave out the kale and add a dash of nutmeg for the classic of quiches: crustless quiche lorraine.
Crustless Spinach Quiche
Swap kale for spinach, skip the meat and double that onion for a crustless spinach quiche any low carb vegetarian would love. When it comes to crustless quiche keto, spinach is a duh, as it’s a mild tasting veggie that’s full of nutrients — but it’s also full of liquid. Be sure to cook the spinach until it’s completely wilted and place it over paper towel to absorb any excess water.
Spinach Bacon Quiche
Spinach bacon quiche makes for the perfect combination of healthy, meaty and delicious!
