Kale quiche made in the Instant Pot? Yes, it’s true! This Instant Pot quiche takes just 10 minutes to prep and is loaded with nutritious vegetables, a creamy egg base, and cheesy flavor throughout. The caramelized onions in there take it over the top. You won’t even notice that it’s an Instant Pot crustless quiche instead of one with a crust – much like you don’t miss out on flavor with Instant Pot egg bites, either!

One of the reasons I love quiche in the Instant Pot is that it’s easy to make any time of year, even if you don’t want to turn on the oven, but it’s simple and can be served for any meal of the day, all year round. Breakfast? Yes. Brunch? Of course. Lunch? Definitely. Simple dinner? Even better!

This recipe comes from the cookbook, The Art of Great Cooking with Your Instant Pot, and has been reprinted with permission. And it’s just as amazing as my other egg dishes you can eat any time, such as a crustless zucchini quiche, vegetable frittata, crustless quiche caprese, and the perfect omelette.

This Instant Pot keto quiche recipe was originally published on December 13, 2017, and the post was republished in December 2020 to add updated pictures, useful tips, and some improvements to this healthy kale quiche. (Namely, I removed the raisins that the original had, as they added sugar and I didn’t feel they were needed.)

How To Make Quiche In The Instant Pot

So, wondering how to make quiche in the Instant Pot? It’s actually very simple. And, the Instant Pot does all the work.

FYI: You’ll need a 1.5 quart casserole dish with a glass lid, like this one for this recipe. Make sure the one you have will fit inside the Instant Pot, because you can’t make this without it.

Then…

Sauté. Add butter to Instant Pot and press “Saute.” When butter has melted, add mushrooms, onions, garlic, and dried thyme, cooking until lightly caramelized. Add kale and saute another minute, until wilted. Press “Keep Warm/Cancel” button.
Make egg base. In a large bowl, whisk eggs and cream together. Mix in sea salt, lemon zest, shredded cheddar cheese, and the mushroom-kale mixture, stirring to combine.
Assemble. Pour the egg mixture into the greased dish…

…And dollop ricotta over it.

Pressure cook. Place a trivet inside the Instant Pot and pour 1 cup water into the bottom. Carefully transfer the casserole dish to the Instant Pot, place onto the trivet, and cover with the dish lid. Cover the Instant Pot with its own lid and seal the steam release valve. Press the “Manual” setting and decrease the time using the “-” button until you reach 20 minutes. Let it come to pressure and then reach zero.
Release pressure. When the Instant Pot timer goes off and beeps, press “Keep Warm/Cancel.” Allow Instant Pot to release pressure naturally for 10 minutes. Then, use an oven mitt to “quick release” and open the steam valve.
Top. Carefully open the lid and add more cheddar cheese to the top of the quiche. Place the Instant Pot lid back on for 3 minutes to melt the cheese, or broil in the oven for a few minutes.

Instant Pot Quiche FAQs

Can you make quiche in an Instant Pot?

Yes, you can make a quiche in a pressure cooker. And if you’re wondering how this works, or trying to picture it, you aren’t alone.

We’re cooking the quiche in a small, round casserole dish that gets placed into the Instant Pot.

Why is my quiche flat?

Quiche and other egg dishes fall flat when they cool too quickly. As the eggs cook, the air bubbles expand and the egg dish rises, and when it cools, those bubbles contract and the egg dish falls.

To prevent this when making a quich in the Instant Pot, open the lid after cooking, but leave the quiche inside for a few minutes.

Can I make this dairy-free?

Yes, you can make this quiche dairy-free. It won’t be quite as cheesy, but you can:

Omit the cheddar and ricotta cheese – you may want to add an extra egg or two to make up for the volume.
Swap out the heavy cream for coconut cream, which will impart creamy flavor and texture, without the cheese.

Can you use different veggies?

Sure! Just be sure that you saute them in the Instant Pot first, enough to evaporate any excess water in them – so that you don’t end up with a watery quiche. Try a caprese quiche, or a keto spinach quiche, or take your pick of fave keto vegetables here.

Instant Pot Crustless Quiche Storage Instructions

Can you make it ahead?

Yes, you can make quiche ahead, but since this version is so easy, I recommend making it right before serving.

How to store kale mushroom quiche:

Store leftover quiche in the refrigerator for 2-4 days.

Can you freeze quiche?

Yes. Portion into individual servings and freeze until solid. Transfer to a freezer bag and store for 2-3 months in the freezer.

How to reheat Instant Pot egg quiche:

Reheat the quiche in a 350 degree F oven or in a microwave, just until heated through. I haven’t tried reheating it in the Instant Pot.
