Here's a delicious cauliflower souffle full of cheese! It makes a wonderful low-carb side dish that takes little time to prepare. All cooked in the Instant Pot!
Why you'll love it
This is a totally reimagined way to enjoy mashed cauliflower. This gluten-free souffle makes it easy to eat low-carb. It is delightfully fluffy and aromatic, with a rich taste that fills you up.
Plus, this is a pressure cooker or Instant Pot recipe!
Baking comfort food is so easy when you use the Instant Pot. All you have to do is mix all the ingredients and then let the pot do all the hard work.
Since it is a pressure cooker, you don't have to use a preheated oven (which is fantastic in the summertime). No more filling your kitchen with extra heat!
This cauliflower mixture really does taste like a rich souffle. You are going to love how easy it is to make and how you can make a few changes to make it taste just like you want.
You only need a handful of simple ingredients to make gluten-free souffle. Here's some more information about what I used in this cauliflower recipe.
I used an entire head of cauliflower. You'll use a food processor to puree it all, so it doesn't take much extra work.
Some types of souffle separate the egg yolks and egg whites. I just used two whole eggs to emulsify the ingredients together.
Whenever you cook low-carb recipes, use full-fat cream cheese. You should also soften it to make it easier to mix.
Use either sour cream or yogurt to add some creaminess and tanginess. Greek yogurt will give it a boost in protein and calcium!
A little heavy cream enhances the flavors in this cauliflower mixture. Use full-fat!
If you need to decrease the dairy ingredients, you can use coconut cream instead of heavy cream.
Use Asiago cheese for sure because it has a bold flavor that stands out. Then, add some mild or sharp cheddar cheese to it for the creaminess.
Either salted or unsalted butter will both work perfectly in this recipe.
Fresh chives are ideal, but you can make this recipe with dried chives.
Top this recipe with crispy no-sugar bacon pieces. It is optional, but really makes a huge difference!
Please note: Check out the recipe card at the bottom for a full list of ingredients used to make this low-carb recipe.
- Use a food processor. This purees everything together and makes it soft and fluffy without any extra work from you.
- Cook with a trivet. I placed the cauliflower mixture into a 1 ¼-quart casserole dish and then set it on top of a trivet. The trivet separates the casserole dish from the water beneath it. Use a pot-in-pot and a small push-up cheesecake pan.
- Use enough water. A pressure cooker works by creating steam from the water. If you don't use enough water, you could get a BURN warning.
It’s super easy to make a cauliflower souffle at home. You just need to blend all the ingredients together, place the mixture in a pan, and then cook it in the electric pressure cooker. So simple!
Process the ingredients
Add the eggs, cream, cream cheese, sour cream, and both types of cheese to a food processor and process until smooth and frothy.
Add chopped cauliflower and pulse for 2 seconds at a time until it is chunky. Fold in chives and butter.
Set in the pressure cooker
Pour the mixture into a round casserole dish. Add some water to the bottom of the Instant Pot and put the trivet in the bottom of the pressure cooker.
Place the casserole dish on top of the trivet.
Lock the lid and cook at high pressure for 12 minutes. Do a natural pressure release after 10 minutes.
Garnish and serve
Top with crumbled bacon, and serve!
️ Serving suggestions
If you enjoy easy recipes, then you should give this cauliflower dish a try.
This is a wonderful recipe to serve with zucchini fritters! The fluffy souffle and the crunchy fritters are amazing together.
With all the cream and cheese I used, it is filling enough to serve as the main course. If you do serve it as the main dish, I suggest adding bacon so that it has more protein.
This Instant Pot cauliflower souffle is a great low-carb side dish to serve at holiday dinners, too. I love that it cooks up quickly in the pressure cooker.
If you are going to bring it to a family holiday dinner, bring some cranberry keto trail mix with you for the appetizer!
There are a lot of different ways you can change up this recipe. If you make any adjustments, please let me know in the comments.

- Cook it in the oven. This will cook it to a golden brown color.
- Make it spicier. Add a dash of cayenne pepper or paprika to the mixture.
Below are some questions people often ask about making this keto side dish. If you don't see your question in this list, please leave it in the comments.
A souffle is a French recipe that is usually served sweet as a dessert. It is traditionally made with beaten egg whites that are whipped until stiff peaks form. As it bakes, a classic souffle will bubble over the top of the dish.
My version is savory and uses whole eggs instead of egg whites.
No, you do not need to use milk in this recipe. The light texture is achieved from the combination of sour cream, heavy cream, and cheese.
You don't need any almond flour in this recipe. The cauliflower and cheese work together to make a light and fluffy souffle that is plenty thick.
There are 5 grams net carbs in each serving of this savory souffle.
One of my favorite ways to use the electric pressure cooker is for steaming vegetables. I have a steamer basket that I insert that sits above the water.
It doesn't take long for vegetables to cook under pressure. And, I find they come out much better than with the stovetop method.
For pressure cooker cauliflower, I add a half cup of water and steam for 3 minutes. Then, I let it sit for a couple of minutes before releasing the pressure.
A few of the other things I've done in the pressure cooker are spaghetti squash and no noodle lasagna.

Can you explain what size the cauliflower should be when added to recipe?
Cauliflower florets and chunks should be about 1 to 1.5 inches.
I don't have a pressure cooker. Can this be made in the oven or crock pot?
You can make it in the oven instead. I'd try at 350°F for about 20-25 minutes or until it looks done.
Made this as part of our meal prep. I'm sorry I waited to try it, it is delicious! Followed the recipe exactly, turned out perfect. Definately making again.
You can thank Jill from ThisOldGal.com as she gave me the inspiration for this recipe.
I tried this last night in my instant pot and the pot turned itself off before it finished cooking- there wasn’t enough water in the pot and it was all gone. I added more water and restarted but when it ended the soufflé still wasn’t set. I baked it in the over for another 20+ minutes. The recipe tasted good but it didn’t work well in my IP
It worked in my 6 quart IP without issue.
Are you supposed to grate the cheese prior to putting in the food processor? Or use the grate blade as you put in the cheese and then change to the chop blade for the cauliflower?
I use the grate blade or a hand shredder.
I love your recipes!
This dish looks so delicious too..I really want to make it!
My problem is, that I don't have a pressure cooker.
Can I make it in any other way?
You can bake it in the oven (350F) until set.
I have made a version of this as a Faux Mashed Potatoes when I low carbed years ago. That recipe also called for finely chopped almonds (not almond flour) mixed in with the cauliflower after it was pureed to give it a bit of texture.
I just tried a pot roast in my instant pot last night as a first instant pot experiment. It turned out nice. Can't wait to get to the store for ingredients to try this recipe! Looking forward to seeing (and sharing) instant pot recipes.
I'm just starting to experiment with cooking meat. I made turkey bread and it was moist and tender.
This Cauliflower Soufflé looks delicious! I can't wait to try it out :).
It's super tasty. You should give it a try!
How much butter?
I used about 2 tablespoons.
Made this tonight - it was excellent! I even have the exact casserole dish you used. (I had to cook it for an additional 5 minutes to get the center to set a bit more.). Thank you for the recipe!
So glad it worked out for you Janice. Thanks for the info on needing additional cook time. It does cook during the 10 minute natural pressure release as well so maybe your pressure was releasing a little faster.
What size casserole dish?
I used a 1-1/2 quart (1.4L) French White round casserole dish by CorningWare.
Hi there, how would I be able to receive more of your recipes for electric pressure cookers? I just got my pressure cooker and I would like to get more recipes.
I'm slowly adding more. In fact, I made one today that should post soon. Just do a search on the site for "Instant Pot" or "pressure cooker" to find them.
Looks like a great holiday recipe! Could it just be baked in oven instead of using a pressure cooker?
You can certainly bake it if you'd like. I'd try 350°F until done, likely 45 minutes or more.
