Meal prepping can be a game-changer when it comes to saving time and money, but it often feels like a daunting task that requires hours of planning and cooking.

However, with the right recipes and a little bit of organization, you can create delicious and nutritious meals for the week in just one hour.

One of the best ways to streamline your meal prep is by making use of your freezer and preparing casseroles in advance.

By doubling or tripling a casserole recipe and freezing the extra portions, you’ll have a stash of ready-to-reheat meals at your fingertips whenever you need them.

This not only saves you time on busy weeknights but also helps you stick to your budget and eat healthier by avoiding the temptation of takeout or processed foods.

In this blog post, we’ve rounded up 15 of the best make-ahead freezer casseroles that are perfect for one-hour meal prep.
