What I love most about this recipe is that the base recipe is totally customizable. I prepare these in individual portions in 8oz mason jars so everyone can add their favorite flavorings and toppings and take them along if they like.
Chia seeds are a great addition to oats. They're packed with fiber, protein, healthy omega-3 fats, and antioxidants, making this a nutrient-rich breakfast.

Ingredients - Notes & Substitutions
Overnight oatmeal with chia seeds requires 4 essential ingredients, while the rest is more about personal preference and finishing. Here's a look at what we need:
For Base Recipe
- Rolled Oats: Go for old-fashioned rolled oats for the perfect chewy texture. I don't recommend quick oats or steel-cut oats since they require different soaking times.
- Chia Seeds: These tiny black seeds add fiber, omega-3 fats, and antioxidants, and also thicken the oatmeal as they soak.
- Almond Milk: I like using almond milk for its nutritional value and low-carb count, but you can also use oat milk, cashew milk, coconut milk, or dairy milk.
- Maple Syrup: Use regular or sugar-free maple syrup. Keep it low-carb with monk fruit maple syrup, or keto-friendly allulose syrup.
Carb Comparison Note: With regular maple syrup, each serving of this oatmeal has around 9 grams of net carbs, whereas, the net carbs stay under 0.5 grams if using Lakanto sugar-free maple syrup.
Toppings & Flavor Choices
- Toppings: add color and sweetness with fresh fruit like strawberries and blueberries, or try raspberries, blackberries, or chopped apples. Nuts like almonds or pistachios add a great texture and flavor.
- Optional Flavors: Ground cinnamon adds natural floral sweetness and ground cardamom adds a floral aroma and flavor.

How to Make Overnight Oats with Chia Seeds
This overnight oats recipe with chia seeds is so quick and easy. I like to soak the oats and chia seeds for at least 8 hours for optimal texture, but they can be ready in 2 hours.
Prepare the base oatmeal: Add rolled oats, chia seeds, almond milk, and maple syrup in a mason jar or any jar with a lid (Pics 1-4).
Stir: Stir everything until well combined and there are no clumps of chia seeds (Pics 5-6).
Refrigerate: Cover and refrigerate overnight for best results, or at least 2 hours.
Top and serve: Top your overnight oats with chopped strawberries, blueberries, and sliced almonds. Optionally, add ground cinnamon or cardamom (Pics 7-8). Enjoy!
Note: For a grab-and-go breakfast option, top with fruits and nuts the night before, but don't mix. Mix it before serving.
Serving Suggestions
Serving temperature: Overnight oats with chia seeds can be had cold, at room temperature, or warm. To warm them, pop them in the microwave for 30-40 seconds before adding any fruit. For best results, consume the chia oats within 2 days, since it gets too gummy beyond that.
Toppings: I top my chia oats with fresh fruits like blueberries, cut strawberries, blackberries, or chopped apples. Other cut fruits that work well are mango, peaches, pears, and pineapple. I also top it with assorted nuts like almonds or pistachios for a crunchy texture and healthy fats.
Flavorings: A dash of ground cinnamon or cardamom adds a pleasant flavor to the oatmeal, it is optional though.
Mix-ins: You can also stir in a tablespoon of Greek yogurt to boost the protein content. That also makes the texture creamier.
How to Store
You can store chia seed overnight oats in the refrigerator in a mason jar or any glass jar with a tight-fitting lid.
Overnight oats stay good for 2 days in the fridge. After the 2-day mark, their texture breaks down too much.
Flavor Variations
Here are 4 inspiring flavors to make these overnight oats your own:
- Indian flavors: Take inspiration from Kheer and add ¼ teaspoon of cardamom and a tiny pinch of saffron during soaking. Finish with pistachios.
- Rice-pudding style: Use dairy milk for the best flavor and add ¼ teaspoon cinnamon. Finish with sliced almonds.
- Tropical: Use coconut milk and add ⅛ teaspoon vanilla extract. Finish with diced pineapple, mango, or unsweetened coconut flakes.
- Brownie Batter: Add 1 tablespoon cocoa powder and 2-4 teaspoons chocolate chips.
Recipe Tips & Notes
- Oats: Rolled oats work better for this recipe since quick oats or steel-cut oats do not absorb liquid the same way. Opt for certified gluten-free if that is a dietary concern.
- Sweetener: Keep it low-carb with Lakanto sugar-free maple syrup or 1 teaspoon of allulose blend. Feel free to use regular sugar or maple syrup.
- Milk: I use almond milk for its nutritional value and for keeping it low-carb, but you can use dairy, oat, cashew, or coconut milk too.
- Oats and Chia Seed Ratio: You can change the quantities of rolled oats and chia seeds based on your preference. Another possible combination can be ¼-cup rolled oats + 2 teaspoons chia seeds.
- Oats-to-Liquid Ratio: Use a 1:2 oats + chia seeds ratio to milk. If you prefer fewer chia seeds, stick to the quantity mentioned above.
Frequently Asked Questions
Overnight oats are typically served cold. But if you prefer warm overnight oats, pack them in a microwave-safe jar. The next morning, warm them in the microwave in 30-second increments, stirring each time in between.
Chia seeds contain fiber, protein, healthy omega-3 fats, and antioxidants. A small amount goes a long way and they're a wonderful nutrient boost to add to your diet.
Chia seeds and oats should soak in the liquid for at least 2 hours, but the longer they soak, the more liquid they absorb. For creamier results, soak for at least 8 hours.
