I still remember the first Monday morning I tried this. The alarm went off at 6:15, the kids were already making noise in the hallway, and I had exactly zero minutes to make breakfast. I opened the fridge, grabbed the little jar I had prepped the night before, and that was it. A thick, creamy, actually-filling breakfast I could eat standing at the counter. No cooking. No stress. Just a really good start to the day.
That is when overnight oats became a permanent part of my kitchen routine. If you have been looking for a healthy breakfast you can make ahead and actually look forward to eating, this overnight oats recipe with chia seeds is the one. It takes about ten minutes to prep, keeps in the fridge for up to five days, and you can customize it endlessly. I am sharing my base recipe plus four variations that have become reader favorites.
Key Takeaways
- This is a true make-ahead breakfast that stores well for up to 5 days in the fridge
- Chia seeds are the secret to a thick, creamy texture and an extra protein and fiber boost
- Only whole rolled oats work here — quick oats go mushy and steel-cut stay too tough
- The perfect ratio is 1/2 cup oats to 2/3 cup milk to 1 tablespoon chia seeds
- Four flavor variations included: Apple Pie, Peach Crisp, PB&J, and Chocolate Banana Bread
Overnight Oats with Chia Seeds
Ingredients
Method
- Add the rolled oats, chia seeds, maple syrup (or honey), sea salt, and Greek yogurt (if using) to a mason jar or lidded container.
- Pour in the milk and stir thoroughly, making sure to scrape the bottom and sides to prevent chia seed clumping.
- Seal the jar and refrigerate for at least 4 hours, preferably overnight.
- In the morning, stir well. If the oats are too thick, add a small splash of milk to loosen the texture.
- Add desired toppings and enjoy cold, or microwave for 1–2 minutes to serve warm.

Let us know how it was!Why You Will Love This Overnight Oats Recipe
Busy mornings are the number one reason people skip breakfast. But skipping it often means reaching for something less nutritious by mid-morning. This recipe solves that in the most practical way possible. You do the work the night before, and morning-you just opens a jar.
What makes this the best overnight oats recipe is not just the convenience. It is the texture. When I first started making overnight oats, I used only oats and milk, and while that worked fine, it felt a little thin. Adding chia seeds changes everything. They absorb the liquid overnight and create this thick, pudding-like consistency that actually feels satisfying. Think somewhere between creamy oatmeal and chia pudding.

This recipe is also endlessly flexible. Dairy-free? Use almond milk or oat milk and skip the yogurt. Want more protein? Stir in Greek yogurt or a scoop of protein powder. Vegan overnight oats are just as easy — swap honey for maple syrup and skip the dairy entirely. The base stays the same; you just adjust what goes in the jar.
Overnight Oats Ingredients and Why They Matter
Good ingredients make a simple recipe great. Here is what goes into this healthy overnight oats recipe and why each one earns its place:
- Whole rolled oats — Also called old-fashioned oats. These are the only type that work correctly. Quick oats absorb too much liquid and turn to mush. Steel-cut oats do not soften enough overnight and stay chewy and tough.
- Chia seeds — These are the texture game-changer. One tablespoon per serving adds protein, fiber, and healthy omega-3 fats while creating that thick, creamy consistency. According to the Harvard T.H. Chan School of Public Health, chia seeds are a strong source of fiber and plant-based omega-3 fatty acids.
- Milk of your choice — Almond milk keeps it light and dairy-free. Oat milk adds a subtle sweetness. Coconut milk gives the richest, creamiest result. Whole dairy milk works beautifully too.
- Maple syrup or honey — Just a half teaspoon is enough to balance the oats without making things sugary. Add more on top when serving if needed.
- A pinch of sea salt — This small detail makes a real difference. Salt brings out the flavor of everything else in the jar.
- Greek yogurt (optional) — Stir in a quarter cup for extra creaminess and a solid protein boost. Leave it out to keep the recipe fully dairy-free or vegan.
How to Make Overnight Oats Step by Step
This is genuinely one of the easiest things you can make. The method is straightforward, but there are a couple of small details that make a big difference in the final texture.
Step 1: Add the oats, chia seeds, maple syrup, salt, and Greek yogurt (if using) to a Mason jar or any lidded container.
Step 2: Pour in the milk and stir everything together thoroughly. Pay attention to the bottom and sides of the jar — chia seeds love to clump there. Any clumps that are not broken up will stay that way overnight and create uneven texture.
Step 3: Seal the jar and refrigerate overnight, or for a minimum of four hours. The oats will keep well for up to five days, which makes this perfect for weekly meal prep.
Step 4: In the morning, give the oats a good stir, add your toppings, and eat. If they seem thicker than you like, stir in a small splash of milk to loosen them up.
Meal prep tip: When making multiple jars at once, add all dry ingredients to each jar first, then add the milk one jar at a time and stir each before moving to the next. This prevents chia seed clumping across batches. Wait to add any crunchy toppings like granola, nuts, or seeds until the morning you eat them so they stay crisp. For another great meal-prep-friendly baked option, our Healthy Oatmeal Banana Bread is a great companion to keep in your kitchen all week.
The Perfect Overnight Oats Ratio
Getting the ratio right is the difference between oats that are perfectly creamy and oats that are either too thin or too thick to enjoy. The ratio I use consistently is:
1/2 cup whole rolled oats + 2/3 cup milk + 1 tablespoon chia seeds
When I made overnight oats with just oats and milk, equal parts worked fine. But once chia seeds entered the picture, I found I needed a bit more liquid to compensate for what the seeds absorb overnight. If you add Greek yogurt, keep the milk at 2/3 cup — the yogurt adds its own moisture and creaminess.
4 Overnight Oats Variations Worth Making
Once you have the base down, the variations are where the fun begins. These four are the ones I make most often and the ones that consistently get the best feedback. They are all built on the same base recipe — you just stir in a few extra ingredients or pile on specific toppings.
1. Apple Pie Overnight Oats
Stir two tablespoons of unsweetened applesauce and a quarter teaspoon of cinnamon or apple pie spice into the base before refrigerating. In the morning, top with diced fresh apple and chopped toasted pecans. If you happen to have cinnamon-cooked apples on hand, add a spoonful of those too. The flavor is remarkably close to the inside of an actual apple pie.
2. Peach Crisp Overnight Oats
This one is deceptively simple. Make the plain base overnight, then in the morning layer on fresh or thawed peach slices and a generous handful of granola. The granola gives you that crisp contrast against the creamy oats. It is a summer breakfast that works any time of year when peaches are available.
3. Peanut Butter Overnight Oats
This is the one people ask about most. Make the plain base overnight, then top in the morning with a spoonful of creamy peanut butter, a layer of strawberry chia jam, chopped fresh strawberries, raspberries, and a handful of toasted peanuts. The chia jam takes about ten minutes to make on the stovetop and is completely worth it — it has a concentrated berry flavor that store-bought jam cannot match. For a twist, swap in almond butter and toasted almonds instead.
4. Chocolate Banana Bread Overnight Oats
Mash half a ripe banana and stir it into the base along with one teaspoon of cocoa powder, a quarter teaspoon of cinnamon, and a pinch of nutmeg before refrigerating. In the morning, top with banana slices, chopped walnuts, and a few chocolate chips. The flavor is genuinely reminiscent of a slice of chocolate banana bread. If you love baked banana flavors, you will also enjoy our Super Moist Chocolate Chip Banana Bread.
Tips, Variations, and Storage
Beyond the four variations above, the mix-in and topping possibilities are essentially endless. A few directions worth exploring:
- Stir in a scoop of vanilla or unflavored protein powder for high protein overnight oats — this is currently one of the top-rising searches in the US for this recipe category
- Add a tablespoon of peanut butter or almond butter directly into the base for richness
- Try seasonal fruit toppings: blueberries in spring, peaches in summer, diced pears or apples in fall
- Sprinkle coconut flakes, hemp seeds, or flaxseed on top for extra nutrients
- For a vegan overnight oats recipe, use plant milk, maple syrup instead of honey, and skip the yogurt
- For overnight oats without chia seeds, use equal parts oats and milk (1/2 cup each) and increase yogurt to 1/3 cup for creaminess
Storage: Covered jars keep well in the refrigerator for up to 5 days. Do not freeze them — the texture breaks down and becomes watery after thawing. Always add fresh toppings the morning of eating.
Frequently Asked Questions
What kind of oats should I use for overnight oats?
Always use whole rolled oats, also called old-fashioned oats. Quick oats absorb too much liquid overnight and turn mushy. Steel-cut oats are too dense and will stay chewy and undersoaked no matter how long they sit. Whole rolled oats hit the perfect balance — soft but with a little body.
How long do overnight oats last in the fridge?
Overnight oats keep well in a sealed jar or container in the refrigerator for up to five days. This makes them ideal for Sunday meal prep. Just hold off on adding any crunchy toppings until the morning you plan to eat each jar so they stay fresh and crisp.
Can I make overnight oats without chia seeds?
Yes, absolutely. Skip the chia seeds and use equal parts oats and milk — about half a cup of each. To compensate for the creaminess chia seeds normally provide, stir in a bit more Greek yogurt. The texture will be softer and less thick, but still very good.
Can I eat overnight oats warm?
Yes, if cold oats are not your thing, transfer the jar contents to a bowl and microwave for one to two minutes, stirring halfway through. Add a small splash of milk before warming to keep the texture from getting too thick. The flavors are just as good warm as cold.
Make It Your Own
