Instant Pot Crustless Quiche Lorraine

Introduction

Instant Pot Crustless Quiche Lorraine is your shortcut to a savory, elegant, and fuss-free breakfast or brunch. By skipping the crust, you get all the classic flavors—smoky bacon, nutty Swiss cheese, and tender eggs—in a creamy, protein-rich dish that’s naturally gluten-free and lower in carbs. Cooking it in the Instant Pot means you can serve up this delicious French classic in a fraction of the time, without worrying about overbaking or a soggy crust.

Flavorful Simplicity for Busy Mornings

What makes this Instant Pot Crustless Quiche Lorraine a standout is its blend of smoky bacon, sharp Swiss cheese, and a custardy egg filling—all mingling perfectly thanks to gentle pressure cooking. Unlike traditional quiche, there’s no need to fuss with pastry, making prep and cleanup a breeze. It’s the ultimate crowd pleaser: simple enough for weekdays but elegant enough for a brunch party.

Prep Your Luscious Egg Filling

Whisk together eggs, cream, and just enough seasoning to enhance the bacon and Swiss. The milk and cream combo ensures a silky texture, while sauteed onions add a subtle sweetness. Layer the bacon, onions, and cheese in your Instant Pot-safe dish, then pour the custard over the top for even distribution.

Assembling and Cooking in the Instant Pot

Lightly grease a 6- or 7-inch ovenproof dish—this will serve as your quiche mold inside the Instant Pot. Assemble your layers, cover tightly with foil to prevent moisture from dripping into the quiche, and set the dish on the Instant Pot’s trivet. Pressure cooking means no need to monitor for doneness; just set and forget until it’s decadently set and ready to slice.

Serving Suggestions for Instant Pot Crustless Quiche Lorraine

Slice your quiche into wedges and serve alongside a simple arugula or mixed green salad dressed in vinaigrette. For brunch gatherings, round out the menu with fruit salad, rosemary potatoes, or a crusty baguette for those who want some crunch.

Instructions

1. Set the Instant Pot to “Sauté” and cook chopped bacon until crispy. Remove with a slotted spoon and set aside. Drain excess fat, leaving about 1 teaspoon in the pot.
2. Add diced onion to the Instant Pot and sauté until soft, about 2–3 minutes. Remove and set aside with the bacon.
3. In a medium bowl, whisk together eggs, half-and-half (or milk), salt, pepper, and nutmeg (if using).
4. Grease a 6- or 7-inch ovenproof dish with butter or cooking spray. Layer in half of the bacon, onions, and cheese. Pour in the egg mixture. Top with the remaining bacon, onions, and cheese.
5. Cover the dish tightly with foil to keep out any condensation.
6. Add 1 cup water to the Instant Pot insert. Place the trivet inside and set the dish on top of the trivet.
7. Seal lid and set to Manual/High Pressure for 25 minutes. Allow a natural release for 10 minutes, then quick release any remaining pressure.
8. Carefully lift out the dish. Remove foil and let the quiche cool for 10 minutes to set before slicing. Garnish with chopped chives or parsley, if desired.
