Ingredients

For cooking:

85 grams rolled oats 1 cup
240 mL milk any kind, 1 cup
240 mL water 1 cup
1 pinch salt optional

To add after cooking:

15 - 30 grams whey protein 2 tablespoons, depending on taste or protein goal
Frozen blueberries add as much as you like
Brown sugar or sweetener of choice optional
Milk or cream to adjust consistency (optional)

Instructions

Combine rolled oats, milk, water, and salt in the Instant Pot. Stir gently.
Seal the lid. Set to High Pressure for 3 minutes. Once done, let the pressure release naturally for 10–15 minutes, then release any remaining pressure manually.
Open the lid and give the oats a good stir. They’ll thicken as they sit.
Add frozen blueberries and stir to thaw slightly. Then stir in the whey protein while the oatmeal is still warm (this helps it dissolve smoothly), but not hot, as the heat can make it curdle to some extent.
If it gets too thick, stir in a splash of milk or water. Finish with a splash of milk or cream to cool the oatmeal a bit and a sprinkle of brown sugar or sweetener of choice.

Notes

Let the oats cool slightly before stirring in the protein powder—this helps it dissolve smoothly and prevents clumping or curdling.
Always add protein after cooking—never before.
Stir the oats well after pressure cooking to help them thicken evenly.
If your oats look watery at first, give them a few minutes—they’ll thicken as they sit.
Use rolled oats, not steel-cut or quick oats—they cook differently.
If the texture feels too thick after cooling, just stir in a little extra milk or water to loosen it.
You can easily double the recipe—just don’t go over the max fill line of your Instant Pot.
