Low Sugar Blueberry Baked Oatmeal Meal Prep Bowls with Greek Yogurt and Chia
Monday mornings are chaotic enough without standing over a stove at 7am. That is exactly why this low sugar blueberry baked oatmeal meal prep recipe exists. You make one big batch on Sunday, slice it into portions, and suddenly five breakfasts are sorted before the week even begins. It bakes up golden on the edges, soft and jammy in the centre, and smells absolutely incredible coming out of the oven. Blueberries bubble and burst through the oats, creating little pockets of natural sweetness that honestly make added sugar feel unnecessary.
What makes this version genuinely healthier than most baked oatmeal recipes you will find is the combination of rolled oats, chia seeds, and plain Greek yogurt. The chia seeds add a serious boost of soluble fibre, which slows digestion and keeps blood sugar stable through the morning. The Greek yogurt gets mixed directly into the batter, bumping the protein content up to around 14 grams per serving without any protein powder in sight. A small amount of pure maple syrup brings just enough sweetness to round things out, but the ripe blueberries do most of the heavy lifting. The total added sugar per serving sits well under 5 grams, which is genuinely impressive for something that tastes this good.
The flavour profile here is warm and subtly spiced. Cinnamon and a touch of vanilla give each bite that comforting, bakery-style depth that makes you actually look forward to breakfast. Fresh or frozen blueberries both work brilliantly, so this is a recipe you can make year round without any compromise on taste. If you use frozen, do not thaw them first. Toss them straight in from frozen and they hold their shape better during baking, giving you those beautiful intact berries rather than a purple swirl through everything. Both options are nutritionally nearly identical, so use whatever is sitting in your kitchen right now.
Meal prepping baked oatmeal is one of those strategies that genuinely changes your morning routine. Once baked and cooled, you can slice the whole dish into six neat squares, store them in airtight containers in the fridge, and reheat each one in about 90 seconds flat. They also freeze brilliantly, which means you can double the batch and stock your freezer for the weeks ahead. Serve each portion topped with a dollop of plain Greek yogurt, a handful of fresh blueberries, or a small drizzle of almond butter if you want extra staying power. This is breakfast that works for you, not the other way around.
Ingredients
- 2 cups rolled oats (use certified gluten-free oats if needed)
- 3 tablespoons chia seeds
- 1 teaspoon ground cinnamon
- 1 teaspoon baking powder
- 1 teaspoon fine sea salt
- 2 large eggs (free range where possible)
- 3 cup plain low-fat Greek yogurt (adds protein and creaminess)
- 1.5 cups unsweetened almond milk (or any milk of choice)
- 2 tablespoons pure maple syrup (this is the only added sweetener)
- 1 teaspoon pure vanilla extract
- 1 tablespoon coconut oil (melted, plus extra for greasing the dish)
- 1.5 cups blueberries (fresh or frozen, do not thaw if frozen)
- 1 tablespoon lemon zest (from about 1 medium lemon, brightens the flavour)
Instructions
- 1
Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Lightly grease an 8x8 inch baking dish with a small amount of melted coconut oil and set aside.
Using a glass or ceramic baking dish gives you more even heat distribution than a metal pan, which helps the oatmeal bake through without over-browning the edges.

In a large mixing bowl, combine the rolled oats, chia seeds, cinnamon, baking powder, and sea salt. Stir everything together until evenly mixed.
- 3
In a separate medium bowl, whisk together the eggs, Greek yogurt, almond milk, maple syrup, vanilla extract, and melted coconut oil until smooth and well combined. Make sure the coconut oil has cooled slightly before adding it so it does not scramble the eggs.
If your Greek yogurt is very thick, whisk it with the milk first to loosen it before adding the other wet ingredients. This prevents lumps in the batter.
- 4
Pour the wet mixture into the bowl with the dry oat mixture. Add the lemon zest and stir everything together until fully combined. Let the mixture sit for 3 to 4 minutes so the oats and chia seeds begin absorbing the liquid.
This short rest time is important. It thickens the batter slightly and means the oatmeal bakes up cohesive rather than watery in the centre.
- 5
Fold in 1 cup of the blueberries gently, then pour the mixture into your prepared baking dish and spread it out into an even layer. Scatter the remaining half cup of blueberries across the top, pressing them in slightly.
Reserving some blueberries for the top gives you those beautiful bursting berries on the surface and makes the finished dish look really inviting.
- 6
Bake uncovered for 38 to 42 minutes, until the centre is set and no longer jiggles when you gently shake the dish. The top should look lightly golden and the edges should have pulled away slightly from the sides of the pan.
Check at the 35 minute mark. Ovens vary and you want to pull it out as soon as the centre is just set to keep the interior soft and moist.
- 7
Remove from the oven and allow to cool in the dish for at least 10 minutes before slicing into 6 equal squares. Serve warm with a dollop of plain Greek yogurt on top, or allow to cool completely before storing for meal prep.

Pro Tips
- ✓
Do not substitute quick oats for rolled oats. Quick oats become mushy during baking and the texture will not hold up for meal prep storage.
- ✓
Frozen blueberries go straight in from frozen, no thawing. Thawed berries release too much liquid and can make the centre of the baked oatmeal soggy.
- ✓
Let the batter rest for at least 3 minutes before pouring it into the dish. This activates the chia seeds and produces a much better texture.
- ✓
For extra protein, serve each square with a side of plain Greek yogurt rather than mixing more into the batter, which can make it too dense.
- ✓
Lemon zest is a small addition that makes a big difference. It cuts through the richness and makes the blueberry flavour taste brighter and more vibrant.
- ✓
If your blueberries are particularly tart, you can add an extra teaspoon of maple syrup to the batter without significantly affecting the overall sugar content per serving.
Frequently Asked Questions
Variations
- •
Lemon Blueberry Baked Oatmeal
Add an extra tablespoon of lemon zest and a teaspoon of lemon juice to the batter for a brighter, more citrus-forward version. Pairs beautifully with a lemon-flavoured yogurt topping.
- •
Mixed Berry Baked Oatmeal
Replace half the blueberries with raspberries or chopped strawberries for a mixed berry version. The flavour complexity is wonderful and the colour is stunning.
- •
Blueberry Almond Baked Oatmeal
Stir 3 tablespoons of almond flour into the dry ingredients and top the dish with a small handful of sliced almonds before baking. This adds healthy fats and a satisfying crunch on top.
- •
Vegan Blueberry Baked Oatmeal
Replace the eggs with 2 flax eggs (2 tablespoons ground flaxseed mixed with 6 tablespoons water, rested for 10 minutes) and swap the Greek yogurt for plain unsweetened coconut yogurt. Use oat milk instead of almond milk for a creamier result.
Substitutions
- •Plain low-fat Greek yogurt → Plain unsweetened coconut yogurt or soy yogurt (Use for a dairy-free version. The protein content will be slightly lower depending on the brand you choose.)
- •Unsweetened almond milk → Oat milk, soy milk, or regular low-fat dairy milk (Any milk works here. Soy milk adds the most protein. Oat milk gives the richest flavour.)
- •Pure maple syrup → Raw honey or a few drops of liquid stevia (Honey works as a 1:1 swap. If using stevia, start with 4 to 5 drops and taste the batter before baking.)
- •Coconut oil → Light olive oil or avocado oil (Any neutral oil works fine here. Coconut oil gives a very subtle sweetness that complements the blueberries nicely.)
- •Chia seeds → Ground flaxseed (Use the same quantity. Ground flaxseed provides similar fibre and omega-3 benefits, though it gives the baked oatmeal a slightly darker colour.)
- •Eggs → Flax eggs (1 tablespoon ground flaxseed mixed with 3 tablespoons water per egg) (Rest the flax egg mixture for 10 minutes before using. This works well for a vegan version and the texture is very similar.)
🧊 Storage
Allow the baked oatmeal to cool completely before storing. Slice into 6 squares and transfer to individual airtight containers or store the whole dish covered tightly with a lid or plastic wrap. Refrigerate for up to 5 days. To freeze, wrap individual squares in parchment paper, place in a zip-lock freezer bag, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
📅 Make Ahead
This recipe is ideal for Sunday meal prep. The full dish can be assembled the night before and stored unbaked in the fridge overnight, then baked fresh in the morning. Alternatively, bake it fully on the weekend and refrigerate or freeze portions for the week ahead. The texture holds up beautifully after reheating, making this one of the most practical make-ahead breakfasts you can have in your rotation.
