In a 12-ounce or larger jar with a lid, combine the oats, chia seeds, milk, yogurt, vanilla extract, and maple syrup. Stir well.
Fold in the diced strawberries, then secure the lid on the jar and place it in the fridge to chill overnight. (If you plan on eating sooner, 1 to 2 hours should be sufficient to soften the oats.)
When you're ready to eat, grab the jar from the fridge and remove the lid. The oats will be significantly thicker, so add a splash of milk if you'd like to loosen the texture. Enjoy it right away with any extra toppings you love.
Notes
The nutrition information is for the whole batch. It is automatically calculated using generic ingredients, so it's just an estimate and not a guarantee.Rolled Oats Note: If you want to eat this immediately, try making it with quick cooking oats instead. You can enjoy it just like cold cereal in just minutes! If you need a gluten-free recipe, make sure you buy certified gluten-free oats.Make it Vegan: Swap the Greek yogurt and milk for your favorite non-dairy options. If you don't want to use yogurt at all, you can swap it for an extra 1/4 cup of milk. Storage Tip: You can prepare overnight oats up to 4 days in advance, but the strawberries may lose some flavor by day 4. If you want to prep 4 days worth, you might wait to add the strawberries until just before serving for the most fresh taste.
