Peel and pit fresh mango if using, then chop into chunks. Blend the mango chunks into a smooth puree using an immersion blender. Add lime juice a little at a time if you like a tangy twist, tasting as you go.

Meal Prep

Here’s how to prep your oats ahead:

Multiply each ingredient by the number of servings you want.
Mix everything in one big bowl and then divide into individual jars, or prepare each jar separately from the get-go.
Add fresh toppings like nuts or extra mango right before eating for the best texture.

Tips

Mix wet ingredients separately for perfect flavor balance. Combine the mango puree, lime juice, milk, and sweetener on their own first, taste, and then tweak sweetness or lime juice before adding oats to ensure the flavor hits just right.
Warm mango puree when using granulated sugar. If you prefer to sweeten your oats with regular sugar, gently heat the mango puree to help dissolve the sugar evenly and avoid any graininess.
Add extra mango puree on top for a flavor boost. Spoon some fresh mango puree as a topping before eating to deepen the tropical vibe and add freshness.
Explore tropical toppings to complement mango. Think beyond nuts—try shredded coconut, passion fruit, or a sprinkle of toasted pumpkin seeds to layer in interesting textures and flavors.
