Step-by-Step: How to Make Blueberry Baked Oats

Grind half of the oats. Take half of your oats and grind them thoroughly until they resemble a fine flour. If you’re using a blender, set it to high speed and blend for 20 to 30 seconds or until the oats in the container look finely ground and powdery.

Preheat the oven. Set your oven to 180°C (350°F) so it’s ready when your batter is mixed.
Combine and stir dry ingredients. In a large bowl, add the ground oats along with the remaining whole oats. Toss in salt, baking powder, sugar, and lemon zest if you’re using it. Mix these dry ingredients well until they’re evenly combined.

Fold in most of the blueberries. Add the majority of your blueberries to the batter, saving a handful to scatter on top later. Give the mixture a quick stir – be careful not to overmix, or the batter can turn a dull grey color and won’t look as appetizing.

Prepare ramekin(s). Lightly grease your ramekins with a little oil to ensure the oats don’t stick during baking.

Bake for 25 minutes. Place the ramekins in the oven and bake. To check if they’re done, use the clean stick test: insert a toothpick or knife in the center – it should come out clean or with just a few moist crumbs, but not wet batter.
Slowly cool in the oven. When baking time is up, turn off the oven and crack the door open slightly. Leave the baked oats inside for an extra 5 to 10 minutes to let them cool gently and avoid sudden temperature changes.
Serve or refrigerate. Once cool enough, enjoy your blueberry baked oats immediately or store them in the fridge for later.

Variations

Vegan Variation

To make blueberry baked oats vegan-friendly, follow these substitutions:

Replace no-fat Greek yogurt with an equal amount of thick vegan yogurt, such as coconut or almond-based yogurt.
Use unsweetened plant milk (like almond, oat, or soy milk) instead of dairy milk in the same quantity.

High Fiber

To boost the fiber content, add:

1 tablespoon chia seeds (≈ +4 g fiber)
2 tablespoons milk of your choice (helps keep the oats moist after baking)
½ teaspoon white sugar (restores sweetness lost when you add chia)

Preparation:

Combine all dry and wet ingredients (but not the blueberries).
Let the batter rest for 5 minutes—this gives the chia time to absorb liquid and prevents clumps.
Give it a quick stir, add blueberries then transfer to your baking dish.

Tips

Adjust bake time & temperature. Treat your first batch as a test: if it’s undercooked, add 2–3 minutes next time; if the top browns too fast, lower the oven by 10–15 °F (5–8 °C) and keep an eye on the final minutes.
Reheat gently for creaminess. Warm at 300 °F (150 °C) for a couple of minutes or microwave in 20 s bursts, checking between each, to revive heat without drying or toughening the center. The oats are perfectly fine straight from the fridge, too.

Storage

After the blueberry baked oats have cooled, transfer them to an airtight container and store in the refrigerator for up to 3 to 4 days.
