Start your day off right with vegan high-protein overnight oats! I have four different flavour options, so there’s something for everyone.

High-protein overnight oats in jars with toppings

Overnight oats are the quintessential meal prep breakfast. Not only are they easy to prepare, but they can be made in bulk so you have breakfast ready for days.

While I’ve shared Strawberry Coconut Overnight Oats, Peanut Butter Banana Overnight Oats, and Espresso Cinnamon Overnight Oats in the past, if you’re looking for an overnight oats recipe that’s loaded with protein, this is the one for you! Greek yogurt, protein powder, and chia or flax seeds give these oats a boost in protein, making for a supremely satisfying breakfast.

Below, I share recipes for chocolate mint, chocolate peanut butter, vanilla strawberry, and almond butter pretzel high-protein overnight oats. Which will you choose?! (I recommend not choosing and trying them all!)

Are Overnight Oats Healthy?

Yes, overnight oats are a healthy breakfast option. Oats are a great source of fiber, but this vegan high-protein overnight oats recipe is also high in protein to help you build and maintain muscle and stay fuller longer. Depending on the ingredients you add, overnight oats can also deliver vitamins, minerals, antioxidants, and healthy fats.

Notes on Ingredients

Scroll down to the recipe card to find the ingredient quantities and recipe instructions.

For the Base:

  • Rolled oats – Also known as old-fashioned oats.
  • Chia seeds or whole flax seeds – If you’re not a fan of the texture of these seeds, try adding hemp hearts instead.
  • Salt
  • Non-dairy milk – Use vanilla or unflavoured.
  • Vegan plain or vanilla Greek yogurt
  • Maple syrup – Or your favourite vegan sweetener.

Flavour Options:

  • Chocolate mint – Vegan chocolate protein powder, cocoa powder, peppermint oil, dairy-free chocolate chips (optional), fresh mint (optional)
  • Chocolate peanut butter – Vegan chocolate protein powder, cocoa powder, peanut butter, dairy-free chocolate chips (optional), peanuts (optional), banana (optional) 
  • Vanilla strawberry – Vegan vanilla protein powder, fresh strawberries, coconut shreds (optional)
  • Almond butter pretzel – Vegan vanilla protein powder, almond butter, banana (optional), almonds, pretzels, dairy-free chocolate chips (optional)

Which Non-Dairy Milk Is Highest in Protein?

Soy milk contains the most protein per cup of all traditional non-dairy milks (not counting those that are fortified). It averages 7 grams of protein per cup, so if you want to give your high-protein overnight oats an even bigger protein boost, choose soy milk for this recipe.

How to Make High-Protein Overnight Oats

Overnight oats need several hours in the fridge to soften up—hence the name! Be sure to make them the night before you plan on eating them.

Combine the dry ingredients. Stir together the oats, seeds, and salt in a small bowl.

Add the liquid ingredients. Stir in the non-dairy milk, vegan yogurt, and maple syrup.

Add the flavourings. Choose the flavour you’d like to make and stir those ingredients into the oats, minus any toppings.

Chill. Transfer the oat mixture to a food-safe airtight container and refrigerate overnight, or up to 3 days.

Serve. Stir the oats, add any toppings, and enjoy cold.

Tips for Success

These tips will help you make sure your vegan high-protein overnight oats turn out perfect!

  • Don’t make more than you can eat in a few days. Beyond 3 days, the oats start to go bad, so don’t make more overnight oats than you can eat within that timeframe.
  • Meal prep it. If you’re making overnight oats for breakfast meal prep, I recommend doubling or tripling the base recipe, then dividing it to create multiple flavor combinations for the week.
  • Use rolled oats. Quick oats will be too mushy, and steel-cut oats won’t soften enough in the fridge.

More Variations

The beauty of these high-protein overnight oats is that they are highly customisable. Add vanilla protein powder with fresh peaches, diced mango, or just about any fruit. Chocolate protein powder is delicious with raspberries, antioxidant-rich cacao nibs, and pomegranate arils. Add matcha powder or espresso powder for a boost of caffeine, or top your overnight oats with homemade granola or coconut whipped cream.

How to Store

Store vegan high-protein overnight oats in an airtight container in the refrigerator for up to 3 days.

Yes, you can freeze high-protein overnight oats in a freezer-safe bag or container for up to 3 months. When ready to eat, thaw overnight in the refrigerator, give it a good stir, and add your favourite toppings.
