About This Recipe
If you’re looking for an easy, make-ahead breakfast, you have to try these Basic Overnight Chia Oats. They’re made with simple pantry staples like rolled oats, chia seeds, milk, and a touch of sweetener, and become perfectly thick, creamy, and satisfying overnight in the refrigerator.
I love how simple this recipe is because it instantly makes each jar super customizable. You can enjoy these oats plain, or dress them up with fresh berries, sliced banana, nut butter, yogurt, chocolate chips, granola, or whatever toppings you have on hand.
Plus, they’re perfect for busy mornings, meal prep, or an afternoon snack when you need something filling and nutritious.

Ingredients and Substitutions
- Old-fashioned oats: Use gluten-free if needed.
- Milk: I used unsweetened SILK cashew milk, but any milk of your choice works.
- Protein powder: Grab your favorite protein powder. My favorite brands are Clean Simple Eats, or for a dairy-free option, I love Active Stacks! Use LILLIE for a discount.
- Chia seeds: Any type of chia seeds (black, white, or a mix) works for this recipe. Chia seeds are a great source of omega-3s and protein. They will absorb the liquid overnight and expand in size, so don’t worry if it doesn’t look like a lot when initially mixed.
- Vanilla extract: Adds warmth and sweetness without extra sugar.
- Sweetener: I prefer to use a liquid sweetener like liquid stevia or monk fruit for these overnight oats. I personally just like how the liquid blends in, but any type of sweetener will work! You can also use honey, maple syrup, agave, etc.
Dietary Adaptations
GF/DF: Make sure to use gluten-free oats and a dairy-free protein powder (Active Stacks is my favorite). Their chocolate is elite, but the vanilla is good too.

How To Make
- Combine everything in a jar or other lidded container and refrigerate for at least four hours or overnight.
- Remove from the fridge and add more milk if you like it thinner. Garnish with whatever toppings you like! We love fresh or frozen fruit, nuts, granola, nut butter, etc.
