Keto Jalapeno Popper Cauliflower Casserole (2024)

This Keto Jalapeno Popper Cauliflower Casserole has all the flavors of your favorite jalapeño popper appetizer, but in a low carb and family friendly casserole format! Keep it as is for a keto vegetarian casserole, or add bacon to jazz it up a bit! Low carb and gluten free.

As you know, Mondays are for low carb meatball recipes here on IBIH. Lately, I feel like I’ve also gotten into the habit of posting variations of the low carb cauliflower casserole recipes on Wednesdays. I’m not committing to a cauliflower Wednesday or anything – though I probably could, since this cauliflower casserole alone is so versatile that there is no end to the flavor combinations one could come up with!

It’s a delicious rut to be stuck in, and I plan to explore the many possibilities over the coming months (though not always on Wednesdays, because let’s face it, I’m not that organized.)

My latest low carb cauliflower creation is this Keto Jalapeno Popper Cauliflower Casserole. It’s an impossible task to figure out which is my favorite so far between this one, the insanely popular Pepperoni Pizza Cauliflower Casserole, or the Mexican inspired Cheesy Chipotle Cauliflower Casserole.

Honestly, they are all fantastic. Let’s just say that I love this one AT LEAST as much as the others, if not a hair more.

Creamy, cheesy, spicy – this Keto Jalapeno popper cauliflower casserole has it all! Super kid friendly (and picky husband friendly too), this recipe makes a great keto side dish, though I’ve also eaten it with a salad as a main course. I hope you guys will love it at least as much as I do!

As a side note, as you can see by the photos we cooked this in our new Wood Fired Oven that Mr. Hungry built – it works just as well in a regular oven though, or even the microwave, if you’re pressed for time with all of the back to school chaos coming up!

One last thing, the pictures don’t show it, but when I ate this Keto Jalapeno Popper Cauliflower Casserole leftover the next day I added some crumbled bacon on top – Mind. Blown. I’ve listed the bacon as optional in the recipe (crazy, right?) since without it, this dish is vegetarian friendly as well. Otherwise, you can, and should, feel free to pile bacon on this sucker with wild and reckless abandon!

Description

A low carb cauliflower recipe inspired by the jalapeno popper! Kid friendly, this is a recipe the whole family will love! Serve as a side, or with a salad for a main dish!

Ingredients

Scale

  • For the puree:
  • 1 head of cauliflower
  • 2 Tbsp heavy cream
  • 1 Tbsp butter
  • 1/4 cup sharp cheddar cheese, shredded
  • 1 Tbsp raw jalapenos, chopped
  • 1/4 tsp garlic powder
  • salt and pepper to taste

For the cream cheese layer:

  • 6 oz cream cheese, softened
  • 1/2 cup shredded cheddar cheese
  • 1/4 cup salsa verde

For the topping:

  • 3/4 cup colby jack cheese, shredded
  • 1/4 cup raw jalapenos, sliced (seeds removed)

Instructions

  1. For the puree:
  2. Clean and trim the cauliflower, breaking it into medium sized pieces. Place in a microwave safe bowl with 2 Tbsp of cream and 1 Tbsp of butter. Microwave, uncovered, on high for 10 minutes. Stir to coat cauliflower with cream/butter mixture. Microwave for another six – eight minutes on high (or until cauliflower is tender). Remove from the microwave and put into a high speed blender or food processor along with the cheese, jalapenos, and garlic powder. Puree until smooth (or you can leave it chunky if you prefer. Season generously with salt and pepper to taste.

For the cream cheese layer:

  1. Put the cream cheese in a microwave safe bowl and nuke for 30 seconds to soften. Add the shredded cheese and salsa verde, mixing thoroughly. It should be very spreadable – if not, nuke for a few more seconds.

To assemble the casserole:

  1. In a medium-sized oven proof dish (approximately 8 x 8), spread out a thick layer of cauliflower puree. Spread the warm cream cheese mixture on top of the puree. Top with a layer of shredded colby jack cheese, and sliced jalapenos. Bake at 375 degrees for about 20 minutes, or until the cheese is completely melted. You can finish it under the broiler for a couple of minutes to brown further if you’d like. Alternatively, microwave on high for about 6 – 8 minutes, or until the cheese is melted and the casserole is heated through. Serve hot.
  2. Optional – top with cooked, crumbled bacon before serving.

    I wanted something to go with my carne asada… My store was out of jalapenos =(
    So I grabbed poblanos and serrano peppers/chiles. I also had frozen cauliflower but wanted texture so I didn’t blend it. I roasted my chile and ingredients for my salsa on the barbecue. I creamed my cream cheese with about 1/4 cup of sour cream in the food processor, along with a rough chop of the roasted poblanos. Added monterey jack cheese. Added cheddar cheese and serranos on top. Reminded me of a Bobby Flay dish I make… Fabulous!! Carne Asada, Cauliflower Casserole, and Grilled onions and peppers…will be a staple dish at my house!

    Just made this for the first time. DELICIOUS! One of the best cauliflower recipes I have ever had. The only thing I added was some cooked cubed chicken that I had tossed in some paprika and cayenne seasoning for extra protein. Thank you so much for sharing this recipe. I will definitely make again.

    Oh he** yeah! This was so flippin’ good! Reminded me so much of a dish called Pepper Soufflé, no idea why it was called that ; there wasn’t an egg in sight. Lol! I added 2 cups chopped rotisserie chicken and was just wowed! I used frozen riced cauliflower but didn’t blend, all sharp cheddar (plus cream cheese) and loved the texture and flavor! Thank you!!!!

    Just made this and it came out amazing! I decided to go the “chunky” way because it was still pretty early and didn’t want to wake anyone up with my blender. Next time I’ll make it with a blender.

    We love this recipe…but we actually like cauliflower and don’t have a problem with eating mashed potatoes. That a given… We half cook the cauliflower-do not blend it but leave it in clumps and follow directions after that. Amazing!!!!
    Friends and co-workers love it this way as well.

    OMG is this sooo good!!! My husband loved it too! I just ate my luch at 11:15 because I couldn’t wait any longer to eat the leftovers!!

    Turns out my blender sucks, so my cauliflower was chunky- which was still great! I would double up on jalapenos next time for a little more spice!

    Hi there,
    I just ran across your site and love it! I’m doing a version of the ideal protein diet and like yours better because it includes avacado and some dairy. Do you know why they would omit it…maybe slows the weight loss? I would like to be a convert! :)

    I used five jalapenos, added cooked chicken and used a bit ahem more cheese and this was delicious. Next time I’ll double the cauliflower.

    Absolutely delicious. I roasted my cauliflower florets first (w/olive oil, fresh garlic & seasonings) then kind of improvised with the steps since I rarely use my microwave to cook. I must say I absolutely loved this and will become a regular addition to our meals.

    Boom Baby! You did it again Dahling! I loved this so much, I wanted to take a bath in this, put it in my pillowcase so I could eat some during the night, face plant myself right into the bowl…too much? Ah well, next time I will put more jalapeno in it…I like it spicy! Every recipe has been so good. I thank you so much for trying these and perfecting them for us LCHF minions!

    Is there anything else I can use in place of the salsa verde? Or do you think it would be ok just to leave it out?

    Thanks!

    • Mellissa Sevigny says

      You can leave it out Judy, but it will change the flavor a bit – not sure if regular salsa will work the same because of the tomato flavor but you could try it. Enjoy!

    Hi,

    I know I’m a little late to the party here, but I just made this yesterday. It was delicious, thank you! I agree about the bacon, I had my first portion of it in a bacon bowl and it was awesome. I also had a bit of a the puree left over since my cauliflower was massive; it worked great for a slightly spicier base for the “potato” skins recipe elsewhere on the site. Thanks for sharing all your great recipes!

    I don’t understand 2 things :

    1. How much is a head of cauliflower? I have seen some large ones (around 3# before cutting) and small ones (around 1 1/2# before cutting) so I am having trouble here.
    2. When i spec this out with 600g of cauliflower I only get 271cal but with 5net carbs and 22g Fat. Am I picking out wrong ingredients in MFP using the recipe import feature?

    Thanks

    Sounds good to me, but if you haven’t tried the recipe as written, I recommend giving it a go first. It’s really not that spicy even with all the jalapeños. These two additions will really jazz this recipe up.

    If I didn’t have a microwave, I’d cook the cauliflower in a small (2-3 Tbl.) amount of water in a covered pot. Keep the heat no higher than medium, and don’t lift the lid. Give the florets about 15 minutes, then check for doneness. THEN add cream and butter and stir until butter melts.

  36. Jamie says

    How would you prep the Cauliflower if you do not have a microwave? Just steam it then add the cream, or would it bettern heated with the cream in a covered sauce pan? or?

    Reply

    • Mellissa Sevigny says

      Steaming it in the saucepan with the cream and butter would work great. Just be sure to bake long enough for the cream and butter to reduce in the oven until it’s thick and not watery – enjoy!

        Beautiful recipe. Thank you for sharing. Thought I’d post a suggestion to research how microwave ovens kill all the food nutrients by radiating them. You may want to look into that for the better health of you and your loved ones. Blessings and thank you for sharing your art.

    I made this recipe tonight as a side dish (served with London Broil) and it was a-mazing! I didn’t have salsa verde so I substituted chopped pickled jalapenos. It was absolutely delicious and now I want to buy more cauliflower so I can make it again!

    Could someone please please tell me what jalapeño popper is. I’m not in America so cannot buy it but I don’t know what it is :'(

    Reply

    • Tyffany says

      Judy, a jalapeno popper is an American appetizer made by stuffing a jalapeno pepper with cheese and sometimes other ingredients, then breading and deep frying. A jalapeno pepper, which is the ingredient called for in this recipe, is a hot green chili pepper which is usually about 3 inches long and about 3/4 inch in diameter at it’s widest point. If fresh jalapeno peppers are not available where you live, a similar hot pepper would probably be a good substitution. Here in America, jalapeno peppers are also available pickled in jars, so you might look for those.

      Hope this helps!

    Do your children gobble this up with the tablespoon of jalapeños or do you leave them out? How about the peppers on top?

    Reply

    • Mellissa Sevigny says

      The peppers in the mix don’t really add much heat – the peppers on top I would do at your discretion depending on how spicy your family likes things – maybe half with and half without?

    I like to use cauliflower in a base for “cream of…” soups. Just nuke the florets until tender, add a half of an onion, diced and sauteed, if you wish, then put in a blender with just enough chicken stock (or other stock, depending on what kind of soup you are making), and puree until smooth. Add the main ingredient : broccoli, red peppers and shrimp, spinach, cheddar cheese, whatever… I usually have these cooked, but not always… and puree again, unless you want to leave some as chunks. Add additional stock as needed, and perhaps 1/4 cup or so of cream. Season as desired and serve. These soups are good hot or cold (I was on a cold fennel soup kick this summer… so good!), and can go lots of ways depending on what seasonings you use (curried soups are great!).

      Wow thank you so much for your tip on the “cream of” soup substitute! I am not a fan of cauliflower so that’s an amazing way to sneak it in :)
