This Strawberry Protein Baked Oatmeal is the perfect make-ahead breakfast for busy mornings. What I love about this Breakfast is that it’s filling, lightly sweet, and packed with nourishing ingredients... plus it is freezer friendly!

I’ve been making this for years when I want something I can prep once and eat all week. It makes great leftovers and is easy to switch up with different fruits depending on what you have on hand.

Freezer Instructions

1. Cool completely.
Never freeze hot food. Let it cool completely first (you can even refrigerate it overnight). Before sealing, wipe away any condensation inside the container to help prevent ice crystals from forming.

2. Portion it for real life.
Freeze the amount you'll actually use. If your family won't eat a whole casserole in one night, divide it into smaller portions instead. Smaller portions also thaw much faster.

3. Leave a little room.
Don't fill containers all the way to the top, foods expand slightly as they freeze.

4. Label everything.
Write the recipe name and the date on each container so you know exactly what's waiting in your freezer.

5. Freeze.
I love freezing meals in 2-cup silicone freezer cubes. They're the perfect size for lunches or small dinners, stack beautifully, and thaw much faster than one giant frozen block.

How to Reheat

For best results, transfer your meal to the refrigerator the night before.

If it's still a little frozen in the center, microwave on the Defrost setting in 5-minute intervals until it can be broken apart easily.

Then simply reheat like you would any leftovers:

Bake casseroles in the oven.
Warm soups, pasta, and skillet meals on the stovetop.
Use the microwave for quick meals.
The air fryer works great for foods that should stay crispy.

My favorite freezer rule: Reheat food the same way you originally cooked it whenever possible. It almost always gives you the best texture.

Storage Tip: For the best flavor and texture, enjoy freezer meals within about 3 months.
