🥣 What is baked oatmeal?

Unlike your typical bowl of oats, baked oatmeal is served casserole style. Generally, it’s made from a base of rolled oats, milk, eggs, and other pantry staples. From there, berries, nuts, chocolate chips, spices, and other mix-ins can be added to create different flavors.

The texture is meant to be similar to bread pudding rather than creamy and porridge-like. So if you’re not a fan of traditional oatmeal, this baked berry oatmeal may be the answer!

Just mix everything together, add it to a dish, and wait as it transforms into a golden-brown masterpiece! It works great for meal prep too! Just make a large batch at the beginning of the week, and you’ll have quick and easy breakfasts for days.

🌱 Is baked oatmeal vegan?

Traditionally, baked oatmeal recipes include ingredients like eggs, milk, and butter. However, it’s incredibly easy to make a vegan baked oatmeal recipe with a few swaps. Here’s how it’s done:

• Eggs: Replace eggs with mashed banana, applesauce, pumpkin puree, or sweet potato puree. In addition, use flax eggs (ground flaxseeds and water).
• Milk: Substitute regular milk with your favorite non-dairy alternatives like soy milk, almond milk, cashew milk, oat milk, or pea milk.
• Butter: Use dairy-free butter or coconut oil!

🤔 Which oats work best for baked oatmeal?

The best oats to use for vegan baked oatmeal are old-fashioned rolled oats. They provide a perfectly chewy texture without turning out too mushy.

You can use quick oats in a pinch, but you won’t achieve the same textural characteristic baked oatmeal is known for. And we don’t recommend using steel-cut oats as they require a much longer baking time.

🛒 Ingredients & substitutions

• Pecans: Provide a toasty crunch all throughout the vegan baked oats. Use pecans, walnuts, cashews, macadamia nuts, or pistachios.
• Rolled oats: Make sure you have old-fashioned rolled oats for the best texture. If you have gluten sensitivities, double-check that the oats are labeled “gluten-free.”
• Baking powder: Gives the oat batter lift, preventing a dense vegan baked oatmeal. You’ll want baking powder, not baking soda!
• Cinnamon: Ground cinnamon adds sweet, warming flavors. Ceylon cinnamon is the better choice compared to cassia cinnamon, both in taste and health effects.
• Salt: Brings out the other flavors, adding depth to the baked oatmeal.
• Coconut sugar: Sweetens the recipe while creating layers of rich, complex, and caramel-like flavors. Brown sugar also works, just make sure it’s vegan-friendly.
• Flax egg: Binds the oat mixture together. Ground chia seeds also work as a 1:1 replacement.
• Vegan butter: Adds richness and moisture, preventing a rubbery texture. No vegan butter on hand? Substitute it with coconut oil or more mashed banana.
• Soy milk: We typically use plain, unsweetened soy milk. If you use a sweetened variety, reduce the overall sugar added. Oat milk is another favorite!
• Banana: Mashed banana adds natural sweetness and moisture. Make sure it’s extra spotty! If not, use unsweetened applesauce, pumpkin, or sweet potato puree.
• Vanilla extract: We always recommend pure vanilla extract over artificial. It’s worth the splurge!
• Berries: We used frozen mixed berries, but we love fresh berries when they’re in season. Feel free to use only blueberries, raspberries, blackberries, or strawberries.

📝 How to make vegan baked oatmeal

Step 1: Make the flax egg

Preheat the oven to 350 degrees F and lightly grease a 9×9 baking dish with coconut oil or vegan butter. Mix the ground flaxseed and water in a small bowl. Set aside for 5 minutes to thicken.

Step 2: Toast the nuts

When the oven is ready, toast the chopped pecans on a baking sheet for 3-4 minutes, or until lightly browned and fragrant.

Step 3: Whisk the dry ingredients

In a large mixing bowl, whisk together the rolled oats, baking powder, cinnamon, salt, and coconut sugar.

Step 4: Mix the wet ingredients

Melt the vegan butter in a heat-safe bowl. Add it to the bowl of dry ingredients along with the soy milk, flax egg, mashed banana, toasted pecans, and vanilla.

Step 5: Layer the berries

Cover the bottom of your baking dish generously with frozen berries (about 1 ½ cups). Layer the oatmeal mixture over the berries, then add the remaining berries on top.

Step 6: Bake the oats

Bake for 35-40, or until the oats reach your preferred consistency. Bake them less for a softer texture, or bake them longer for firmer slices. Let the dish rest for 10 minutes, then serve warm. Happy eating!

🌡️ Storage & reheating

For leftover vegan baked oatmeal, follow these storage and reheating tips:

• Fridge: Keep your baked oatmeal in the refrigerator for 5-6 days. It’s best to transfer it to an airtight container or wrap slices in cling wrap and aluminum foil. 
• Freezer: Freezing is the best way to keep vegan baked oats fresh for longer periods of time (especially if you’re meal-prepping). Just cut it into single-serving portions and freeze them in a freezer-safe bag or container for up to 3-4 months.
• Reheating: When you’re ready for breakfast, heat slices in the oven at 350 degrees F for about 5-7 minutes, or until warmed through. Alternatively, microwave them in 20-30 second intervals.

♻️ Variations

• Chocolate chip: Create an even more dessert-like vegan baked oats by swapping out the berries for dairy-free chocolate chips. You can also add a dash of cocoa!
• Apples and cinnamon: For an oatmeal classic, mix in diced apples and cinnamon. For extra soft apples, cook them for a few minutes in a skillet with vegan butter.
• Maple and brown sugar: Another fan favorite! Replace the coconut sugar with brown sugar, and add maple syrup in place of some mashed banana.
• Peanut butter and jelly: Top vegan baked oatmeal slices with natural peanut butter and your favorite jam or jelly. There is no better combo!
• Pumpkin spice: During cool fall months, start your morning with pumpkin spice vegan baked oatmeal. Add 2 teaspoons of pumpkin spice, replace the banana with pumpkin puree, and substitute the berries with more pecans or chocolate chips.

🧑‍🍳 Top tips

• Prep flax eggs first: You’ll need about 5-10 minutes for the flaxseed and water mixture to thicken. Combine these before anything else!
• Use rolled oats: For the best texture and slightly sweeter flavor, use old-fashioned rolled oats instead of quick or steel-cut oats.
• Let the bananas ripen: Make sure your banana is extra ripe, which will provide natural sweetness and a creamier texture.
• Add a touch of salt: We can’t stress adding salt enough! It really brings out the sweet flavors of recipes like baked berry oatmeal.
