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.

Can you use stackable pot n pot pans and make two quiche at a time? If so how do you adjust cook time or is adjusting cook time necessary?

  Hi Phyllis, I have never used a stacking pan, so I can’t say for sure if this would work.

Can you use a springform pan instead of a casserole dish?

  Hi Laurel, I have never tried to make this recipe in a springform pan. If you try let me know the results.

I re-read the recipe but see no raisins included, and can’t imagine them in this quiche, either. Your letter must belong somewhere else. Hmm!

  Hi Beverly, This recipe has been changed and republished to no longer include raisins.

Can I use frozen kale/spinach in this recipe. BTW, all your recipes have been a hit in my house. Thank you so much.

  Hi Edmeral, Yes, but let defrost and squeeze the excess water out before using. Some of the water will work out during the saute process, but it will take a lot longer if you don’t remove the excess liquid first.

We made this today for breakfast and it was very good! I subbed a 5 oz. clamshell of Baby spinach and arugula for the kale, and cottage cheese for the ricotta, both due to using what I had on hand. It cooked up so nice and moist, we really enjoyed it. The lemon was subtle, but it really enhanced the flavor. Make sure to include it if you have it! I know we will have this again!

I have never made quiche myself but I was intrigued by your recipe. I must say that we licked every bit of it and loved it. Will definitely make it make it gain.

I’m just curious what the Instant Pot brings to the party here? Don’t misunderstand, I use mine all the time, but in this recipe, it isn’t saving much time, or using less cookware. I make crustless quiche all the time in the oven. Perhaps this cooks the egg custard better somehow?

  Hi Dale, The prep process in the Instant Pot is not really adding anything special to the recipe. The magic is in the final cooking process. Pressure cooking this dish gives it a unique lightness and texture that you wouldn’t get by baking this in the oven. I hope you give it a try!

Hi. Fairly new to Instant Potting. The recipe has varying measurements fir different number of servings. (Thanks for that!) If I cut it to 3 servings, does that change the cooking time? By how much?

  Hi Rosemary, I think it might reduce the cook time a bit, but not sure for how long since this wasn’t my recipe (it was from a friend’s cookbook referenced in the post). I think a better option is to make the whole recipe and save any extra for leftovers. 🙂

Lovely recipe. However, being a Type 2 diabetic, I would omit the raisins which also lowers the carbs to 7 total carbs per serving, 6 net carbs per serving.

  Thank you for sharing! Yes, you can definitely omit the raisins.

Hi, Do I need to use an Instant Pot? I don’t have one but would like to try the recipe in my oven. Can I do that just like I cook my other quiche recipes?
- Maya | Wholesome Yum
  0 December 18, 2017Reply
  
  Hi Florence, Yes, the oven should be fine! Just do the saute part on the stove and the baking in the oven. I haven’t tested it so don’t have an exact time, but it should be similar to other quiche recipes.

Kale really does a number on my tummy. I can manage swiss chard. Can it be subbed for the kale? Will it change the cook times? I just love my Instant Pot. Thanks, D

  Hi Dee, Yes, I think you can definitely use Swiss chard! The cook times should be the same.
