What Are Overnight Oats?
Definition and Origin
Overnight oats are a no-cook oatmeal preparation method where oats are soaked in liquid—typically milk or a dairy-free alternative—overnight in the refrigerator. By morning, the oats absorb the liquid, become soft and creamy, and are ready to eat cold or warmed up. This preparation originated from “Bircher Müesli,” a Swiss breakfast dish developed over a century ago, now modernized into countless variations globally.
Basic Preparation Method
Making overnight oats is incredibly simple. Here’s the base recipe:
- ½ cup rolled oats
- ½ cup unsweetened almond milk (or preferred milk)
- 1 tablespoon chia seeds (optional for added fiber and texture)
- 1–2 teaspoons of natural sweetener (like honey, maple syrup, or stevia)
- Optional: ¼ cup Greek yogurt for creaminess and protein
Mix all ingredients in a mason jar or sealable container, refrigerate for at least 6 hours (or overnight), and enjoy in the morning.
Nutritional Benefits
Overnight oats are naturally rich in:
- Fiber: Helps you stay full longer, supports digestion
- Complex Carbs: Sustained energy release throughout the morning
- Plant-based Protein: Especially when combined with chia seeds or yogurt
- Micronutrients: Including iron, magnesium, and B-vitamins
By making strategic choices like using unsweetened almond milk and portion-controlled fruits, you can keep your bowl of oats well under 300 calories, making it a low calorie breakfast powerhouse.
Benefits of Low Calorie Overnight Oats
Supports Weight Management
Low calorie overnight oats are ideal for anyone looking to shed pounds or maintain a healthy weight. They’re naturally filling, thanks to a high fiber content from oats and chia seeds. Fiber slows digestion, helping you feel full longer, which can reduce your overall calorie intake throughout the day.
By sticking to low calorie ingredients like unsweetened almond milk, fresh fruits, and minimal natural sweeteners, you can keep your breakfast under 300 calories without sacrificing flavor or satisfaction.
Saves Time in the Morning
One of the biggest perks of overnight oats is that they’re completely ready by the time you wake up. No cooking, no cleaning, no hassle. If your mornings are rushed, prepping overnight oats the evening before ensures you still start your day with a healthy, energy-packed meal..What Kind of Algae Is in Almond Milk Yogurt

Nutrient-Dense and Balanced
Even though they’re low in calories, overnight oats can be incredibly nutrient-dense. A single serving can deliver:
- Whole grains from oats
- Healthy fats from seeds and nut butters
- Natural sweetness from fruits
- Protein from Greek yogurt or plant-based options
This balance keeps your blood sugar levels stable and provides sustained energy for hours.
Customizable to Any Diet
Whether you’re following a vegan, vegetarian, gluten-free, or dairy-free diet, overnight oats can easily be tailored to your needs. Swap regular milk for oat milk, yogurt for coconut yogurt, or add vegan protein powder—the possibilities are endless.
Cost-Effective and Sustainable
Oats are one of the most affordable pantry staples available. When paired with in-season fruits and store-brand alternatives, low calorie overnight oats become not only a healthy but budget-friendly breakfast solution.
Essential Ingredients for Low Calorie Overnight Oats
Rolled Oats – The Core Ingredient
Choose old-fashioned rolled oats over instant oats. Rolled oats maintain a chewy, hearty texture after soaking, while instant oats can become mushy. Plus, rolled oats have a lower glycemic index, which helps stabilize your blood sugar..Best Cowboy Caviar Recipe
Unsweetened Almond Milk – The Light Liquid Base
Unsweetened almond milk is a low calorie liquid perfect for soaking oats. It adds a creamy texture with just 30–40 calories per cup. You can also try oat milk, cashew milk, or skim milk if preferred.
Chia Seeds – Fiber and Texture Booster
Just one tablespoon of chia seeds adds fiber, omega-3 fats, and a slight gel-like texture that makes your oats feel thicker and more satisfying. At just 60 calories, they pack a powerful nutritional punch.
Greek Yogurt – Protein and Creaminess
Adding a scoop of plain nonfat Greek yogurt boosts the protein content and makes the oats creamier. It also provides calcium and gut-friendly probiotics—an excellent way to stay fuller longer.
Natural Sweeteners – Keep It Light
Instead of loading your oats with sugar, use:
- Stevia or monk fruit sweetener (0 calories)
- Maple syrup or honey (in small amounts)
- Mashed banana or apple sauce for natural sweetness
This keeps your breakfast enjoyable without derailing your calorie goals.
Toppings – Flavor Without the Calories
Stick to toppings like:
- Fresh berries (low in sugar and high in antioxidants)
- Sliced banana
- A sprinkle of cinnamon or nutmeg
- Unsweetened coconut flakes
- Chopped nuts (in moderation)
Aim to stay under 100 calories for toppings to keep your oats within the low calorie range.

Frequently Asked Questions
Can I use steel-cut oats instead of rolled oats?
While you can use steel-cut oats, they require a longer soaking time and result in a much chewier texture. They also don’t soften as well overnight unless parboiled. For best results, stick with old-fashioned rolled oats.
How long can I store overnight oats in the fridge?
Overnight oats can be stored in the refrigerator for up to 4–5 days in an airtight container. This makes them perfect for weekly meal prep. Just stir before eating and top with any fresh fruit right before serving.
Are overnight oats suitable for diabetics?
Yes, if made without added sugars. Choose recipes with low-glycemic fruits like berries and avoid sweeteners like honey or maple syrup. Opt for stevia or monk fruit and pair oats with protein and healthy fat to slow down glucose absorption.
Can I warm up overnight oats?
Absolutely! Although typically eaten cold, you can warm them in the microwave for 30–60 seconds if you prefer a hot breakfast. Just be sure to use a microwave-safe container.
What’s the best container for overnight oats?
Glass mason jars with lids are the gold standard—easy to clean, BPA-free, and they seal tightly. You can also use plastic containers or small Tupperware, but avoid using containers that may stain or retain odors.
Can I add protein powder to overnight oats?
Yes! Adding ½ scoop of your favorite protein powder is a great way to boost protein content. Just reduce other sweeteners slightly, as many powders are flavored or sweetened. Blend well to avoid clumps.
