Classic Baked Oatmeal Recipe for Hearty Breakfast

Here at Fit Foodie Finds, we’ve been known for one thing in particular: oatmeal. For over a decade we’ve perfected simple, reliable oatmeal recipes — and this classic baked oatmeal is a favorite. It’s a wholesome, comforting breakfast that often tastes like dessert for the first meal of the day.

This baked oatmeal is straightforward to prepare and great for feeding a family or bringing to a weekend at the cabin. The base relies on rolled or quick-cooking oats, mashed banana, eggs, almond milk, a little maple syrup and a pinch of cinnamon. To keep things fun, I like to divide the baking dish into quadrants and top each section differently so everyone gets their favorite combination.

How to Make Baked Oatmeal

This recipe is intentionally simple. Everything mixes right in the casserole dish, which keeps cleanup to a minimum. Follow these easy steps:

  1. Mash the banana & add wet ingredients: Place mashed banana in the bottom of the baking dish, then add eggs, vanilla, maple syrup, almond milk and melted coconut oil. Stir to combine.
  2. Add dry ingredients: Stir in oats, flour, baking powder and cinnamon until evenly mixed.
  3. Top as desired: Smooth the mixture and add your favorite toppings across sections — chocolate chips, banana slices, mixed berries or a peanut butter swirl are all great options.
  4. Bake: Bake at 350ºF (175ºC) until set and cooked through, about 25–30 minutes for an 8×8-inch dish.

Turn Them into Baked Oatmeal Cups

If you prefer individual portions, use a muffin tin lined with paper liners or sprayed with cooking spray. Fill each cup about 3/4 full and bake at 350ºF for 18–20 minutes. These cups are portable and reheat well for busy mornings.

Can You Use Quick-Cooking Oats?

Yes. Both rolled oats and quick-cooking oats work well in baked oatmeal. Rolled oats will give a slightly chewier texture, while quick oats result in a smoother, more cake-like crumb. Either option yields a satisfying, fiber-rich breakfast.

Should Baked Oatmeal Be Refrigerated?

We recommend refrigerating baked oatmeal once it has cooled. It can sit at room temperature for a short period or overnight, but refrigeration will extend freshness and safety. Stored in an airtight container in the fridge, portions will keep well for up to 5 days.

How to Store Baked Oatmeal

Allow the baked oatmeal to cool completely before storing. Slice it into single servings or transfer muffin-style cups into glass or airtight containers. Refrigerate for up to five days. For longer storage, individual portions freeze well in sealed freezer-safe containers or bags — thaw overnight in the refrigerator and reheat gently in the microwave or oven.
