Low Carb Sausage and Cauliflower Casserole Recipe

When my husband is watching his carbs, it’s essential that dinner ideas are as quick and painless as possible. We are so busy that dedicating an hour or more to making dinner during the week is usually an impossibility. That’s why I love quick low carb meals like this… Even if you’re starving, you can fix this quickly enough to stave off the temptation to go through a drive-thru somewhere.

And you know what’s better than a quick low carb dinner? One that the whole family will eat. Yep, this low carb sausage and cauliflower casserole is even kid-friendly. Our son thinks the cauliflower tastes like potatoes in this recipe, so we have to trouble getting him to eat it. It’s packed with veggies, too, so that’s a major plus! Topped with shredded cheddar cheese or eaten as is, I think you’ll really enjoy this simple low carb meal.

While you can use fresh cauliflower for this recipe if you’d like, I honestly use frozen cauliflower pieces. You could also use riced cauliflower if you’d like smaller cauliflower pieces. But this works for us, and using the frozen cauliflower is just so convenient. You don’t even need to defrost it first!

Oh, and to keep it kid-friendly, we use mild sausage. You can certainly use hot sausage if you want to up the spice factor. Totally yummy either way.

But let’s get to the recipe, and you can judge for yourself.
