Ingredients You’ll Need

Getting the ingredients right is the secret to making this Classic Baked Oatmeal shine. Each component plays an essential role in creating the perfect balance of creaminess, sweetness, and structure that makes every spoonful comforting and delicious.

• 2 cups rolled oats: The hearty base that provides fiber and a satisfying chewy texture.
• 1½ cups milk (dairy or plant-based): Adds moisture and creaminess to bring the oats together as they bake.
• 2 large eggs: Bind the ingredients and give the oatmeal structure without heaviness.
• ⅓ cup honey or maple syrup: Natural sweeteners that infuse warmth and balance the cinnamon’s spice.
• 2 tbsp melted butter or coconut oil: Adds richness and helps develop a golden top with satisfying crispness.
• 1 tsp vanilla extract: Elevates the flavors with its sweet, aromatic touch.
• 1½ tsp baking powder: Gives the oatmeal a gentle lift for a fluffy, cake-like texture.
• 1 tsp cinnamon: Brings warmth and a hint of spice that complements the oats beautifully.
• ¼ tsp salt: Enhances all the flavors and balances the sweetness.
• Optional Mix-Ins: 1 cup berries or diced apple/banana, ¼ cup nuts or seeds, and ¼ cup chocolate chips or dried fruit—these bring extra bursts of flavor and texture to your Classic Baked Oatmeal.

How to Make Classic Baked Oatmeal

Step 1: Preheat and Prepare

Start by preheating your oven to 180°C (350°F). Grease an 8×8-inch (20×20 cm) baking dish with butter or oil—this ensures your oatmeal doesn’t stick and makes for easy serving once baked.

Step 2: Mix Wet Ingredients

In a roomy mixing bowl, whisk together the milk, eggs, honey or maple syrup, melted butter or coconut oil, and vanilla extract until well combined. This mixture acts as a luscious binder that infuses the oats with both moisture and sweetness.

Step 3: Combine Dry Ingredients

Add the rolled oats, baking powder, cinnamon, and salt to the wet mixture. Stir gently but thoroughly until the oats are fully coated and everything is evenly incorporated, creating a thick, hearty batter.

Step 4: Fold in Your Favorite Mix-Ins

This is where you can personalize your Classic Baked Oatmeal! Fold in fresh berries, diced apples, nuts, seeds, chocolate chips, or dried fruit, depending on your mood and what you have on hand. These add delightful pops of flavor, crunch, and color.

Step 5: Bake Until Perfect

Pour the oatmeal batter into your prepared baking dish and smooth the top with a spatula. Pop it into the oven and bake for 35 to 40 minutes until set and golden on top. You’ll know it’s done when the edges are slightly crisp and the center springs back when touched.

Step 6: Cool and Serve

Allow the baked oatmeal to cool slightly before slicing. This resting time helps it firm up for easier serving and gives the flavors a chance to mellow and meld beautifully.

How to Serve Classic Baked Oatmeal

Garnishes

To elevate your bowl, drizzle your Classic Baked Oatmeal with a little extra maple syrup or honey for added sweetness. Freshly sliced fruit, a dollop of yogurt, or a swirl of nut butter also make gorgeous finishing touches that add creaminess and freshness with each bite.

Side Dishes

Classic Baked Oatmeal pairs wonderfully with a side of fresh fruit salad or a tall glass of cold-pressed juice for a refreshing balance. If you want a heartier brunch, try serving it alongside turkey bacon or scrambled eggs for a mix of textures and flavors.

Creative Ways to Present

Make your Classic Baked Oatmeal extra special by portioning it into individual ramekins before baking for charming single servings. You can also top it with granola or toasted coconut flakes for extra crunch. Another fun idea is to layer baked oatmeal with yogurt and fruit in a glass to create a beautiful parfait-style breakfast treat.

Make Ahead and Storage

Storing Leftovers

Once cooled completely, cover any leftover Classic Baked Oatmeal with plastic wrap or transfer to an airtight container and store it in the refrigerator. It will stay fresh for up to 4 days, making it perfect to enjoy as a quick breakfast or snack throughout the week.

Freezing

To freeze, cut the baked oatmeal into individual portions and wrap each piece tightly in plastic wrap followed by aluminum foil or place them in freezer-safe bags. Frozen portions can last for up to 3 months, allowing you to prep ahead and have a nutritious breakfast ready whenever you want.

Reheating

Reheat your Classic Baked Oatmeal slices in the microwave for 1 to 2 minutes or until warm throughout. If you prefer a crispier top, pop them into a toaster oven at 180°C (350°F) for about 10 minutes. Add a splash of milk or a drizzle of maple syrup after reheating to refresh the flavors.

FAQs

Can I use steel-cut oats instead of rolled oats?

Steel-cut oats have a much firmer texture and require longer cooking time, so they are not the best choice for Classic Baked Oatmeal. Rolled oats absorb liquid better and bake into a softer, more cohesive dish.

Is it possible to make this recipe vegan?

Absolutely! Swap the eggs for a flax or chia egg (1 tablespoon ground flaxseed or chia seeds mixed with 3 tablespoons water per egg) and use plant-based milk and coconut oil or vegan butter to keep it completely vegan.

Can I add more sweeteners or reduce sugar?

Yes, feel free to adjust the sweetness to your preference. The recipe calls for about one-third cup of honey or maple syrup, but you can add more for a sweeter oatmeal or cut back if you prefer it less sweet, especially if you include sweet fruits like bananas or apples.

What’s the best way to make Classic Baked Oatmeal gluten-free?

Using certified gluten-free rolled oats is the key. Oats themselves can be gluten-free, but cross-contamination happens during processing, so choose oats labeled gluten-free to avoid any gluten exposure.

Can this dish be served as a dessert?

Definitely! When enjoyed warm and topped with a scoop of vanilla ice cream or a drizzle of chocolate sauce, Classic Baked Oatmeal transforms beautifully into a comforting, wholesome dessert.
