Our best keto and low carb casseroles

The easiest casseroles start with a protein that’s already cooked — or with proteins that cook quickly. It’s a great way to use inexpensive canned meats, such as chicken or seafood, and provides a tasty way to give leftovers new life.

Combining beef and chicken or using different cuts of meat can work depending on the flavors. Bacon is another good choice because it also adds flavor, additional protein, and tasty fat.

When adding vegetables, choose those that not only taste great together but that also have similar cooking times. Use either all raw or all cooked veggies if possible. For example, raw peppers and raw onions cook at about the same rate.

Chopping vegetables into similar sizes can also help them to cook at the same speed. Remember to adjust your baking time depending on the size of the vegetables you add.

Riced cauliflower, for example, will cook more quickly than larger florets. Some vegetables also benefit from either being steamed or sautéed before they’re added.
