Healthy Overnight Oatmeal
It can be challenging to have a healthy breakfast and stay within your WW points if you don’t prepare ahead of time. Put this recipe together the night before, or meal prep enough for a week at a time, and be assured your breakfast will fit perfectly with your WW plan.
Basic Overnight Oatmeal Recipe
The time saving idea of overnight oats is to mix oatmeal with your milk of choice (skim or unsweetened alternative milk like almond milk, flax milk, soy milk or oat milk are the lowest in points) and allow it to sit in the fridge to thicken. Then when you are ready to eat it, just grab it from the fridge, top with fresh fruit or other toppings (see below), and enjoy! Here are the basic ingredients:
- 1/2 cup oats (old-fashioned or rolled)
- 1/2 cup milk of choice
- 1/4 cup yogurt of choice OR 1 Tablespoon (T) chia seeds and additional 1/4 cup milk
- mix-ins, toppings, and fruits as desired
We add Greek yogurt to our oats recipe to thicken it more and increase the protein. Plain low-fat Greek yogurt is a zero point food on the WW plan for members.
Have you tried incorporating Chia seeds into your recipes? They are popular mix-in because they absorb liquid, promote fullness, and provide additional texture that is similar to tapioca. If you add chia seeds to this recipe, be sure to increase the milk as the seeds absorb quite a bit of liquid and you need enough to thicken the oats.
Overnight Oats Variations
Once you get the basics down for how to make refrigerator overnight oatmeal, there’s no stopping what you can create.
Here are some ideas:
- Add chia seeds – be sure to increase milk for this variation
- Add flax or hemp seeds
- Add PB2 powdered peanut butter (chocolate flavored) along with the banana (also check out our Instant Pot Chocolate Peanut Butter Oatmeal)
- Banana and cinnamon for a banana bread flavor
- Pumpkin and cinnamon for pumpkin pie overnight oats
- Add strawberries, blueberries, or raspberries
- Make carrot cake overnight oats with shredded cooked carrot and pineapple (Check out this recipe for tropical blast oatmeal for a similar variation.)
How to Meal Prep Overnight Oatmeal
This Overnight Oats recipe, also known as Refrigerator oatmeal, is a recipe that screams “meal prep” because it is so easy to make in advance.
Just prepare however many servings you need for the week and store them in the fridge until it’s time to enjoy. It takes just a few minutes to make five servings on the weekend so you have enough for the rest of the work week. This is a great time saver.
Overnight oats stay fresh in the refrigerator for up to 5 days. Do not freeze since the texture becomes too watery when thawed.
You can use cute little mason jars, but don’t worry if you don’t have them. Any container works for storing your oatmeal.
Serve the oats hot or cold and add your toppings of choice.
Weight Loss Overnight Oats in 3 Easy Steps
Step 1 – Whisk together almond milk, Greek yogurt, and honey. Stir in oats.

This recipe is very simple and quick to make. Just whisk together the wet ingredients ,and then stir in the oats.
To reduce calories/points even further, eliminate the honey or use a no-calorie sweetener of your choice such as stevia or monk fruit.

The recipe makes one serving of easy overnight oats. To meal prep breakfasts, multiply by the number of servings you want, such as 5-7 servings for each day of the week or for family members.
Step 2 – Store in an airtight container in the fridge overnight.

Because the oatmeal is not (typically) cooked, your oats need to sit for several hours or preferably overnight. The oats absorb the liquid, making this breakfast thick and creamy.
Step 3 – Top thickened oats with banana slices and peanut butter granola (optional) before serving.

Most people eat overnight oats cold, but you can heat them in the microwave if you prefer.
