As a Registered Dietitian, I love overnight oats because they're an easy way to add more whole grains, fiber, and fruit to your morning with very little work.
I love prepping a few jars on Sunday, so breakfast is already taken care of during busy weekday mornings.
In fact, meal prepping overnight oats is on my college-aged daughter's 'to-do' list now that she'll be living off campus. I've introduced her to this recipe and she's sold - she even packed it to take it to work for lunch today.

Overnight Oats
Overnight oats are made by soaking old-fashioned oats in water or milk (any kind of milk) for several hours. The ingredients are mixed together, usually at night, and then sit in the refrigerator for several hours to allow the oats and chia seeds time to soften.
Overnight oats are made to be eaten cold but can definitely be enjoyed warmed up as well. Perfect for grab-and-go breakfast option.
Ingredient Notes

- Oats Use old-fashioned rolled oats. Do not use quick oats or steel cut oats. Oats are an excellent source of fiber, phosphorus, thiamine, magnesium, and zinc.
- Milk An excellent source of protein and calcium. I use skim or 2% milk. Feel free to use a milk alternative, instead.
- Chia Seeds An excellent source of fiber, omega-3 fatty acids, protein, and calcium.
- Maple Syrup Use pure maple syrup. If you like oats more on the sweet side, add another half teaspoon of maple syrup.
- Seasonings Cinnamon, vanilla extract, and a pinch of salt help optimize flavor.
- Mango Use fresh or frozen mango. I prefer to use frozen mango because it's easier to cut into small pieces.
