Best ways to enjoy it
Keto Crustless Quiche is incredibly versatile when it comes to serving. Slice it into wedges for an elegant brunch, or serve it with a side salad for a light lunch. A dollop of sour cream on top can elevate the flavors even more. Additionally, pairing it with sliced avocado or a hearty green salad adds freshness and a lovely visual contrast.
Storage and reheating tips
To keep your quiche fresh, store any leftovers in an airtight container in the refrigerator. It should last up to 3-4 days. You can easily reheat individual slices in the microwave for a quick meal or warm it in the oven for a better texture. If you want to prepare it ahead of time, you can also freeze portions. Just make sure to wrap it tightly to avoid freezer burn.
Helpful cooking tips
- For added flavor, consider sautéing the vegetables in garlic or adding herbs like thyme or basil.
- You can use half-and-half instead of heavy cream if you want a slightly lighter quiche, but keep in mind it may alter the texture.
- If you’re looking for a spicier kick, try adding a pinch of cayenne pepper or red chili flakes to the egg mixture.
Recipe variations
While this Keto Crustless Quiche is fantastic on its own, don’t be afraid to experiment! You can mix and match based on your preferences: try adding cooked bacon for a smoky flavor or substituting the spinach with kale for a different leafy green. You can also switch up the cheese to use cheddar or feta for a Mediterranean twist.
