Low Carb Mac and Cheese

Isn’t food in a jar cute? It’s all the rage on Pinterest now. It seems like you can find about anything in a jar?? I’m waiting for the Filet Mignon in a jar, personally.

Food in a jar isn’t anything new. A lot of us have used those nifty canning jars for decades. I mean, what else are you going to do with them when canning season is over and you start emptying them out? I ?must have 200 canning jars stored in my high cupboards and I don’t have time to garden or can anymore.

If you ask someone who is low carbing what food they miss most they are likely to have macaroni and cheese on the list, right? Well, I haven’t been happy with the various faux mac and cheese recipes. The texture was weird, the flavor wasn’t what I was looking for… you know the story.

You know what I did, right?

Low carb Mac & Cheese

Yup. I made my own. But not just that. I made mac and cheese that you can cook in a jar. One cheesy serving that you can take to work and cook in the microwave. One comforting meal that has just a few carbs, smells delicious and goes anywhere. You can even make several jars and keep them in your refrigerator for instant meals.


If you want to freeze the jars you can but you will need to blanch the cauliflower before adding it to the jar, ‘k?

It isn’t exactly mac and cheese?? I mean that’s a lot to ask of cauliflower. It is delicious and I bet is completely curbs those cravings for… you know. That stuff.

Recently there have been a lot of comments that the calorie count was much higher than I figured. This was due to a typo in the recipe which called for 1/4 cup of cheddar or 4 ounces… 1/4 cup cheddar is only one ounce – my mistake and I do apologize. The nutrition info is correct. Thanks.

  1. I’m going to try this, but on a larger scale. I’m very worried about using plastic wrap in the microwave!?! I’ll likely use a casserole dish with the standard glass lid instead of a jar with plastic wrap.

  2. The 4 oz are by volume not weight. But 1/4 cup is 2 oz by volume I believe. Anyway I am going to try it. Hungry for a good low carb casserole

  3. If you don’t have extra sharp cheddar cheese, you could add a little grated Parmesan to taste. — maybe 1 tsp for this recipe. It’ a good work around.

  4. Louis is right. You are way off on calorie count. According to fitness pal this recipe is 510 calories per serving. 400 in cheese alone.

  5. Tenika McMillan

    According to myfitnesspal.com with regualr sharp cheddar cheese, heavy cream, and light cream cheese only the calorie intake is around 311.

  6. I wanted to try this but I got over 600 calories using your calculator. The 4oz of cheese is over 400 depending on brand.

  8. I don’t know where you got your info, but the chedar cheese alone is about 300 calories. Could you tell me which cheese you use? Cause the whole recipe is about 510 cals, which is bad unless you want to eat it as a side for your protein.

    1. Louis I use a recipe calculator… I will recalculate it and make any changes but I generally double check. I am on vacay right now so it will be a week or so..

  9. This is excellent. I made my first batch on the stove since that was the recipe I had. I can’t wait to jar these up. I’m hoping this works with broccoli as well. My kids love cauliflower and broccoli with cheese. This would be a great afternoon snack for them.

  10. Had this for dinner tonight since I was craving mac n cheese. It was amazing! I had some left over pizza toppings from Portobello cap pizzas the night before (bacon, mushroom, pepperoni, and chives) added those into the mix once everything was cooked and the hubby and I loved it! My favorite recipe by far! Thank you!

  12. This was amazing. I made this for lunch. I made two jars because hey two is as easy to make as one. I shared it with my oldest who loves cauliflower and cheese and we both loved it. I had it with some grilled chicken as a side dish. Absolutely yumm-o.

  13. You started a low carb blog??? Awesome!! Our weight-loss tales are so similar, and low carb has always worked for me in the past, so here I go. (I just started today THEN found your blog.) Question: I don’t have canning jars AND I don’t have a microwave. (It is an appliance that takes up a lot of room that I hardly use. People ask, “OMG, how do you make popcorn? Or heat up leftovers?!” Umm… on the stove. Hello 1970. 😀 Anyway, how would I cook this if I were going to do it stovetop? What would you recommend?

    1. Dawn, I would partially cook the cauliflower… until it was crisp tender. Then I would heat up the cheese sauce ingredients WITH the cualiflower in it and slow cook it until it was tender. Does that make sense?
