In this article, we share our basic recipe , some topping ideas , and 6 of our favorite recipes .

THE ULTIMATE BASIC OVERNIGHT OATMEAL RECIPE
Below is the basic recipe for making overnight oatmeal for 1 serving. However, it's possible (and recommended) to make a few extra servings to have some on hand throughout the week.
(SERVING: 1)
Ingredients
- 1/2 cup (125 ml) oatmeal
- 1/3 cup (85 ml) milk or plant-based beverage
- 1/3 cup (85 ml) plain Greek yogurt
- 1 tsp (5 ml) maple syrup or honey
- 1/2 tsp (2.5 ml) chia seeds
- 1/2 tsp (2.5 ml) ground flax seeds
Preparation
In a bowl, mix the oatmeal, milk, plain Greek yogurt, maple syrup , chia seeds and ground flax seeds.
Transfer the mixture to an airtight container and refrigerate for at least 2 hours.
Notes
Overnight oatmeal can be stored in the refrigerator for up to 5 days. However, if it contains fruit, such as bananas, it will only last 2 to 3 days in the refrigerator.
VARIATIONS OF "OVERNIGHT" OATMEAL
1. The liquid
In most overnight oatmeal recipes, the liquid used is milk or some other plant-based beverage. By substituting another liquid, such as tea infusion , orange juice , or even espresso , you can vary the flavor of your oatmeal a bit.
2. Yogurt
When it comes to yogurt, it's perfectly possible to vary the flavor. However, keep in mind that flavored yogurts generally contain sugar, while plain yogurts do not. Therefore, we recommend omitting maple syrup or honey from the basic recipe if you're using flavored yogurt.
Finally, it is essential that the yogurt is thick, so preferably Greek or skyr yogurt so that the oatmeal has a nice consistency.
3. Aromatics
The basic recipe we're offering doesn't contain any spices or extracts because we wanted it to be easy to customize. However, adding ground cinnamon , cocoa powder , or even vanilla or almond extract are great alternatives to explore to give your oatmeal a little more flavor!
4. The toppings
Of course, toppings are always a great way to vary the flavors! As toppings, we suggest you include nuts, seeds or dried fruits , nut or peanut butter , fresh fruits , jam or small pieces of dark chocolate .
