Yes, this pasta bake will freeze great! If you’d like to freeze a whole pasta bake, we recommend baking it in a freezable container (like this one) for 40 minutes but skipping the final baking step. Instead, after baking for 40 minutes, you’ll stir in the spinach, top with cheese, then let it sit for about an hour before covering and freezing. Once you’re ready to reheat it, bake for 40 minutes, covered, in a 350°F oven, then and additional 15-20 minutes uncovered, until the cheese is browned and bubbly. If you’d like to freeze individual portions, just bake the pasta all the way through, then spoon into freezer-safe containers. You can reheat individual portions by microwaving for 3-4 minutes, or by baking at 350°F for about 20 minutes.
