Ingredients Breakdown

Every ingredient in this baked oatmeal plays a crucial role in creating the perfect texture and flavor. Here’s what you’ll need and why each one matters:

Old-Fashioned Rolled Oats – The star of the dish, providing a chewy yet tender base. Avoid quick oats, as they can turn mushy.

Milk – Adds creaminess and helps bind the mixture. Dairy or plant-based options like almond or oat milk work beautifully.
Eggs – Give structure and richness, ensuring the oatmeal holds together when sliced.
Maple Syrup or Honey – A natural sweetener that enhances flavor without being overly sugary.

Baking Powder – Lifts the texture slightly, making it lighter than traditional stovetop oatmeal.
Cinnamon & Vanilla Extract – Warm spices and vanilla deepen the flavor, creating that signature cozy taste.
Butter or Coconut Oil – Adds richness and helps achieve a golden top.

Mix-Ins – Blueberries, diced apples, nuts, or chocolate chips add bursts of flavor and texture.

How to Make 1 Bowl Baked Oatmeal – Sally’s Baking Addiction

This recipe is as simple as mixing, pouring, and baking. Follow these steps for perfect results every time:

Preheat & Prep – Start by preheating your oven to 350°F (177°C) and lightly greasing a 9×9-inch baking dish.

Whisk Wet Ingredients – In a large bowl, whisk together the milk, eggs, maple syrup, melted butter (or coconut oil), and vanilla until smooth.
Add Dry Ingredients – Stir in the oats, baking powder, cinnamon, and salt. Mix until fully combined, but avoid over-stirring.
Fold in Extras – Gently fold in your choice of mix-ins, such as fresh berries or chopped nuts.

Bake to Perfection – Pour the mixture into the prepared dish and bake for 35–40 minutes, or until the top is golden and the center is set.
Cool & Serve – Let it cool for 5–10 minutes before slicing. Serve warm with a drizzle of extra maple syrup or yogurt.

Pro Tips for the Best Results

For extra creaminess, use whole milk or full-fat coconut milk.

Let the baked oatmeal rest for a few minutes after baking—it firms up as it cools, making slicing easier.
If using frozen fruit, toss it in a bit of flour first to prevent excess moisture.
Double the batch and freeze half for future busy mornings.

Toast nuts before adding them for a deeper, richer flavor.

Variations and Substitutions

This recipe is incredibly versatile. Here are some delicious ways to switch it up:

Apple Cinnamon – Swap berries for diced apples and an extra pinch of cinnamon.

Chocolate Peanut Butter – Stir in cocoa powder and swirl with peanut butter before baking.
Tropical Twist – Use coconut milk, shredded coconut, and diced mango or pineapple.
Pumpkin Spice – Add ½ cup pumpkin puree and pumpkin pie spice for a fall-inspired version.

Gluten-Free – Ensure your oats are certified gluten-free if needed.
Dairy-Free – Use plant-based milk and coconut oil instead of butter.

What to Serve With It

While this baked oatmeal is delicious on its own, pairing it with the right sides can elevate your breakfast spread:

A dollop of Greek yogurt or whipped cream for added creaminess.
Fresh fruit like sliced bananas, strawberries, or raspberries for brightness.
A sprinkle of toasted nuts or seeds for crunch.

A hot cup of coffee, chai tea, or cold glass of milk to complete the meal.

How to Store and Reheat

This baked oatmeal keeps wonderfully, making it ideal for meal prep:

Refrigerator – Store leftovers in an airtight container for up to 5 days.

Freezer – Slice and freeze individual portions for up to 3 months. Thaw overnight in the fridge.
Reheating – Warm slices in the microwave for 30–60 seconds or in a 300°F oven for 10 minutes.

Frequently Asked Questions (FAQs)

Can I use steel-cut oats instead of rolled oats?
No, steel-cut oats require much longer cooking and won’t soften properly in this recipe. Stick with old-fashioned rolled oats for the best texture.

Can I make this recipe vegan?
Absolutely! Replace the eggs with flax eggs (1 tbsp ground flaxseed + 2.5 tbsp water per egg) and use plant-based milk and oil.

Why is my baked oatmeal too dry?
Overbaking can cause dryness. Check for doneness at the 35-minute mark—the center should be set but still slightly soft.

Can I bake this in a muffin tin?
Yes! Divide the batter into a greased muffin tin and bake for 20–25 minutes for portable baked oatmeal cups.

Is this recipe suitable for diabetics?
You can reduce the maple syrup or use a sugar-free substitute to lower the glycemic impact.
