Easy Baked Oatmeal + 14 Recipes

Easy baked oatmeal + all the best baked oatmeal recipes in one place, with a flavor for every season and occasion! Baked oatmeal is perfect for meal prep and so delicious.

I’ve been sharing one baked oatmeal recipe a month for over a year! I’ve had so much fun coming up with creative flavors and you love making them so it’s a win, win!

Why Baked Oatmeal?

I honestly LOVE all types of oatmeal (and I have a ton of oatmeal recipes here on EBF), but baked oatmeal is definitely one of my favorite ways to enjoy oatmeal. Here’s why:

  1. Topping the list is the fact that it’s the perfect meal prep recipe, but also fancy enough for a brunch. I love making baked oatmeal on the weekend and enjoying it for breakfast all week long.
  2. You only need one mixing bowl and one baking dish for these recipes. Minimal dishes? Score.
  3. The flavor combinations are endless! As you can tell, I’ve shared 14 flavor combinations so far and I don’t see myself slowing down anytime soon.
  4. While many of the baked oatmeal recipes sound indulgent, all of the ingredients in my baked oatmeal recipes are wholesome, nutritious ingredients.
  5. They can be allergen friendly. Sensitive to dairy? Use a dairy-free milk. Need to make vegan? Swap in a flaxseed egg in place of a traditional egg. Gluten-free? Check!

Baked Oatmeal Basics

While baked oatmeal recipes don’t get much easier, there are some pro tips.

The perfect ratio – Customize your own baked oatmeal but make sure you keep the ratio of liquid to oats the same. For most recipes you’ll use 1 part oats to 1 part liquid. I prefer to use unsweetened almond milk, oat milk or coconut milk but any milk works!

Make it vegan – All of my baked oatmeal recipes either call for an egg or a flaxseed egg to bind the dish together. To make a flaxseed egg, mix 1 Tablespoon of ground flaxseed with 3 Tablespoons water and let sit for 5 minutes until the mixture thickens a bit.

Just mix and bake – One of my favorite things about baked oatmeal is that you simply mix all of the ingredients in one bowl and then bake! Super simple and delicious.

Can You Make Baked Oatmeal Ahead of Time?

Yes, you can totally make baked oatmeal ahead of time. There are a couple options that work really well.

Option 1: Bake and Then Reheat Before Serving

  1. Prepare baked oatmeal as the recipe suggests. Once baked, let the oatmeal cool, cover the baking dish and place in the fridge. You can do this 1-2 days in advance. When ready to serve, take oatmeal dish from fridge, cover with foil and reheat in a 350°F oven for about 20 minutes. For individual portions, set toaster oven to 350°F and bake for 5-10 minutes or reheat in the microwave for 1 minute.

Option 2: Prep as Much as You Can Without Baking

  1. Mix together your dry ingredients in a bowl, cover and let sit out on the counter until morning.
  2. Mix together all the wet ingredients in another bowl, cover and store in the fridge until morning.
  3. In the morning, simply mix the wet and dry ingredients together, pour oatmeal mixture into your prepared baking dish and bake as recipe suggests.

Ingredients

  • 2 cups rolled old-fashioned oats

Instructions

  2. Mix dry ingredients: In a large bowl, mix together the oats, baking powder, cinnamon, and salt.
  3. Add in wet ingredients: Add in the milk, sugar, flaxseed, coconut oil, vanilla and bananas. Stir to combine and then add in any mix-ins that you’re using.
