Overnight chia oats are a healthy meal prep breakfast recipe. They’re delicious on their own or topped with your favorite fruit.
Do you ever go through phases of wanting the same food over and over for breakfast? I do! I’ll have days and weeks where all I want is avocado toast with eggs. Then sometimes it’s smoothies and other times it’s these overnight chia oats.
These overnight chia oats are my current go-to because they are SO easy. I can meal prep a single portion for myself or make ahead enough for grab-and-go breakfasts for my husband, my daughter, and myself for a few days.
Plus, with the recipe being so simple, it goes well with most any kind of flavors or fruits I’m craving in the moment (check out some of my favorite variations later in the post!).
These overnight chia oats have just a few simple ingredients, but they provide a variety of macronutrients and micronutrients, too.
- Oats: I like to use old-fashioned oats (be sure to use certified gluten free if needed). Oats are a complex carbohydrate that provide energy along with some protein, fiber, and micronutrients like thiamin, magnesium, phosphorus, zinc, manganese, selenium, and iron.
- Chia Seeds: Chia seeds are a tiny but mighty little seed full of protein, fiber, healthy fats, and micronutrients like B vitamins, calcium, copper, iron, magnesium, manganese, phosphorus, selenium, and zinc.
- Milk of Choice: Exact nutrient profile will vary depending on type of milk used, but this can either provide little (i.e. unsweetened almond milk) or additional protein and fat (i.e. cow’s milk or soy milk).
- Nut or Seed Butter of Choice: Use what you have and what you need (i.e. go with a seed butter if allergic to nuts). But no matter the nut or seed butter used, this will add healthy fats, a little protein, and help keep your overnight oats a little more balanced from a macronutrient standpoint.
- Honey: a little goes a long way, but I find a little sweetness makes these overnight oats immensely more enjoyable. If honey isn’t your thing, you can blend in some dates, use something like stevia or monkfruit, or substitute another sweetener like maple syrup, agave, coconut sugar, or brown sugar. Note: if you have a child under age one that will be consuming this, leave out the honey!
- Collagen Peptides: Collagen is not an essential ingredient to these overnight chia oats. You can make them exactly the same and just leave out the collagen and it will still taste great. But – collagen peptides are one way to add protein without affecting taste or texture. 20 grams of collagen peptides doesn’t change the dish in anyway, yet adds 18 grams of protein.

How to Make Overnight Chia Oats
These overnight chia oats couldn’t be more simple to prepare. Start by whisking together your milk, nut/ seed butter, honey, and collagen.
Simple meal prep tip: if you’re planning on making multiple servings, I love just blending everything into the blender to blend everything quickly and evenly!
Pour your liquid into a mason jar and then add the oats and chia seeds. Seal the mason jar, then shake-shake-shake the overnight chia oats mixture together. Place it in the fridge overnight (or at least a few hours). You can enjoy it as is or top with a half cup of your favorite chopped fruit or other toppings (i.e. nuts, seeds, cacao nibs, mini chocolate chips, unsweetened shredded coconut, cinnamon, etc.).
Overnight Chia Oats Recipe Variations
Because this is such a straightforward recipe, I love making countless variations of it! Here are some of my favorites:

Blueberry Almond Overnight Chia Oats

Raspberry Lemon Overnight Chia Oats
- Same recipe, but use cashew butter and blend the juice and zest from half a lemon into the liquid ingredients. Before serving top with (or stir in) a half cup of fresh (or thawed frozen) raspberries.
