Casseroles are normally a quick and easy way to put a meal together—throw a few ingredients into a casserole tray and then pop it in the oven. But just because casseroles are convenient doesn't mean that they're always delicious or healthy. Many times they're carb-laden and filled with potatoes, rice, and other starchy products.

For people who are trying to avoid carbs in their diet, casseroles might seem off-limits, but that's far from the truth. Here are 15 casserole recipes for the fall that are relatively low in their carb content. Then for more recipes, check out 25 Cozy Soup Recipes That Are Perfect for Weight Loss This Fall.

To help combat the high carb content found in pizza, there's been the innovation of cauliflower crust to pile the toppings and sauce on top of, but make use of your casserole dish this fall by turning that into a warm oven-ready casserole. The meal features one cauliflower head, covered in all the things you'd find on a pepperoni pizza—sauce, black olives, mozzarella cheese, and of course, pepperoni. The casserole is still relatively high in sodium, but it's definitely lower than if you were eating a regular pepperoni pizza, so that's got to count for something.
