This one pan baked oatmeal went viral on TikTok for a reason. It requires 7 ingredients, comes together in one dish and has no added sugar!
If you’ve been around EBF for awhile you know I love baked oatmeal, so when I saw the one pan baked oatmeal recipe go viral on TikTok I knew I had to try it for myself!
You only need 7 simple ingredients and it’s mixed together and baked all in the same dish. That’s what makes it so easy.
As an added bonus, there’s no added sugar. All of the sweetness comes from the bananas and berries, which means it’s lower in sugar and perfect for kids. Olivia gobbles up this baked oatmeal and absolutely loves helping me make it too.
Why You’ll Love This Recipe
- It’s prepped and baked in the same dish. No mixing bowl needed = less dishes!
- There’s no refined sugar. This baked oatmeal is naturally sweetened with just banana and frozen fruit.
- It can be meal prepped for healthy breakfasts all week long or made for brunch.
- Diet friendly! This recipe is gluten-free, dairy-free and vegan.
- bananas – the bananas add plenty of natural sweetness to this baked oatmeal. Make sure your bananas are ripe with some brown spots on them.
- old-fashioned rolled oats – I really like Bob’s Red Mill gluten free old fashioned rolled oats. Oats are naturally gluten-free, but are often cross-contaminated so make sure you’re grabbing gluten-free oats if you have a gluten intolerance.
- chia seeds – chia seeds add omega 3 fatty acids, plant-based protein and fiber.
- cinnamon – I love cinnamon and adding a touch to this baked oatmeal goes a long way.
- almond milk – any non-dairy milk works but I used unsweetened almond milk. You can make your own following my homemade almond milk recipe.
- frozen berries – this adds additional sweetness, some antioxidants and a pop of color to this baked oatmeal! I used a mixed berry blend with strawberries, blueberries and raspberries and evenly distributed them. Some of the strawberries in these mixes are large so I find it best to halve or quarter them. Feel free to use your favorite fresh or frozen fruit here!
- unsweetened shredded coconut – I love the flavor and added crunch the unsweetened shredded coconut adds.
How to Make
This one pan oatmeal is prepped and baked all in the same dish so it really can’t get any easier to make.
First, spray an 8×8 baking dish with cooking spray. Then mash the bananas in the baking dish. Add oats on top of the mashed bananas. Sprinkle on chia seeds and cinnamon, then add almond milk. Stir to combine. Top with frozen berries and shredded coconut.
Bake at 350ºF for 25-30 minutes. Portion baked oatmeal into 6 pieces and drizzle with maple syrup and nut butter for serving.
Notes & Substitutions
I love this baked oatmeal as is, but the great thing about this recipe is that you can customize it however you like! Here are some substitutions and ideas:
- Bananas: Since this baked oatmeal doesn’t have any added sweetener the bananas add a good amount of natural sweetness, so I don’t recommend skipping them. That said, if you’re not a banana fan or have an allergy I bet using applesauce would work well. I’d use 1 cup of applesauce in place of the 2 mashed bananas.
- Chia seeds: If you don’t have chia seeds on hand, you can use flaxseeds, hemp seeds or just skip them altogether.
- Milk: Feel free to use your favorite dairy-free milk or dairy milk. My next choices after almond milk would be oat milk or coconut milk.
- Oats: I don’t recommend using quick oats or steel cut oats for this recipe as the cook times will vary and the texture will likely change.
- Cinnamon: You can skip the cinnamon or swap it with another spice of choice. I bet ground ginger, cardamom or nutmeg would all add a delicious flavor!
- Frozen berries: I love the combo of the frozen mixed berries, but you can definitely use any combo of frozen or fresh fruit. I bet this would be delicious with frozen cherries or with a combo of frozen mango and pineapple for tropical baked oatmeal!
- Coconut: If you’re not a coconut fan or don’t have any on hand, feel free to skip this!
- Add some nuts: I bet chopped almonds or pecans would be delicious and add a nice crunch to this baked oatmeal!
- Add extra sweetness: I love how the sugar in this recipe comes from fruit, but if you are looking for sweeter baked oatmeal feel free to add some maple syrup or honey to the mixture before baking. I’d start with 1/4 cup and you can always drizzle more on top when serving!
- Add protein: Feel free to add some Greek yogurt or protein powder to this recipe to amp up the protein!
- Add chocolate chips: I’ll occasionally make these baked oats more decadent by sprinkling some chocolate chips on top with the fruit! Berries + chocolate = best combo ever!
What to Serve with Baked Oatmeal
I find that I either make baked oatmeal as part of my meal prep for a healthy breakfast all week or for brunch. Either way, it can be a meal on its own, but if you want to serve it with some sides here are some recipes that pair well with it.
- Baked Egg Muffins – I love pairing my baked oatmeal with a savory egg dish and these baked egg muffins are my go-to!
- Fruit Salad – It’s always nice to have extra fruit on the side! I love this simple mixed berry fruit salad.
- Cold Brew Coffee – Definitely have to have some sort of coffee to sip on with my baked oatmeal and I love making my cold brew especially during the summer months. If you’re not a coffee person I also have this iced matcha latte that is delicious.
- Mimosas – If you’re serving this baked oatmeal for brunch mimosas are a must!
How to Store and Reheat
This baked oatmeal is a great meal prep recipe. You can store it in an airtight container in the fridge for 4-5 days or in the freezer for up to 3 months. When freezing, I recommend cutting the oatmeal into portions, wrapping each in plastic wrap and placing the portions in a large freezer bag. The individual servings make it easier for reheating.
To reheat the entire pan of baked oatmeal: cover with foil and reheat in the oven at 350ºF for about 20 minutes or until warm.
To reheat individual portions: set oven or toaster oven to 350ºF and bake for 5-10 minutes. You can also reheat in the microwave for 1 minute. Once warm, add your toppings and enjoy!

This is so ridiculously easy and tasty! I didn’t have any chia seeds, but I decided to add in 2 scoops of chocolate protein powder and roughly 1 tablespoon of powdered peanut butter to give it a protein boost. (I also increased the milk to ~1.5 cups.) The flavors work so well together and I love having my breakfast prepped for nearly a full week. Thank you for another wonderful recipe!
