    Just 2 Net Carbs, an easy keto recipe, that the kids are going to love too. That means you are going to love this keto casserole recipe too.


I’m big on super easy Keto, so I took a little help on the prep time with my ingredients. Using frozen riced cauliflower and frozen peppers and onions saves a lot of time, and the nutritional value is similar to fresh.
If you want to rice fresh cauliflower, by all means, go for it! If you want to cut up fresh peppers and onions, that’s great, too. I’d saute the onions with the ground beef before assembling the casserole, but the rest of the veggies can be layered in just like the recipe is written below.
We often have extra kids around our house, friends of our children, and they are mostly used to Standard American Diet fare. Our daughter had a friend staying with us last week. We knew from other visits that she only liked very home-style flavors. Stacey whipped up this dish from what we had around the house, and it was a huge hit with everyone. Give it a try. We hope your family loves it, too!
This is a good one to make ahead, also. Make a batch early in the week and take it for lunches all week long. Or freeze individual portions in freezer/microwave friendly containers like these that you can buy on Amazon. Then you’ll have a meal ready to pop out of the freezer and into the microwave whenever you need it!
This recipe makes 15 Servings per Pan.

  1. 4 stars
    Love the recipe but it doesn’t specify a serving size. The taste is too good to guess how much is a serving. Or did I just skim over it

  2. Have you tried substituting broccoli in for the cauliflower? I’m not a fan of cooked cauliflower at all.

    1. We haven’t tried broccoli. If you do try it, please take a moment to come back and let us all know how it turns out! I can’t imagine it would be bad, beef and broccoli is a pretty standard pairing.
