Hidden Vegetable Recipe for Toddlers and Kids!

Adding cauliflower rice to this low carb pepperoni pizza casserole makes it easy to get kids to eat their veggies! Additionally, on a keto diet, adding a bit of cauliflower rice is a good way to hide vegetables in a recipe. They’ll never know! This casserole is layered with cauliflower rice, sautéed ground beef and onions, tomatoes (you could use sauce) cheese and pepperoni. We’ve added some optional spices, as usual, our homemade Italian seasoning, in this recipe.

It doesn’t take long to bake – 30 minutes at 400 degrees. And leftovers are fabulous. I think it’s kinda like pizza – just as good for breakfast the next day!

Want More Low Carb Pizza Casserole Ideas?

  • Don’t have ground beef thawed? Try a ground sausage pizza casserole.
  • Want more veggies? Add peppers and mushrooms to your pizza casserole.
  • Want a fancy pizza casserole? Try adding spinach and sliced, fresh mozzarella.

If you don’t want to add tomatoes or prefer a sauce, you can make your own pizza sauce. Actually, I usually make my own, because I’m not a garlic person (shock!) and I like to control my flavors. Try your hand at making your own – we like this Atkins pizza sauce recipe and adding the sweetness is what makes it more “pizza sauce” and less “spaghetti sauce”.
