Can you freeze Baked Oatmeal?
Absolutely. Oatmeal bakes are perfect for freezing and enjoying as a future meal. We love to double the recipe and stash one away in the freezer. You can also make them into oatmeal cup muffins as we did in our Zucchini Banana Baked Oatmeal Cups.
Can fresh blueberries be used instead of frozen?
You sure can. In fact, you can use any berries you like or have on hand. Strawberries, blackberries, raspberries, or a mix like we did in our Mixed Berry Baked Oatmeal recipe.
How to make Blueberry Baked Oatmeal nut-free and dairy-free.
Simply omit the almonds for a nut-free option. For dairy-free, we like to use unsweetened almond milk and melted coconut oil in place of the butter.
