This delicious crustless quiche is made entirely in the instant pot and is the easiest, least messy way to serve breakfast for your family or for a whole crowd. We loaded this quiche with caramelized onions, kale, and shredded gouda. Its a perfect flavor combination that you can serve for breakfast, brunch, lunch, or dinner. Serve alongside a salad with a simple vinaigrette or with your favorite breakfast sides like bacon and toast. You can easily switch up the vegetables or cheese and use the same method to make your own take on instant pot quiche. If you'd like a crispy top, sprinkle the top with cheese after pressure cooking and toast under the broiler.
