Something I wish more people knew as a dietitian is that healthy eating can actually be really easy.

This balanced recipe takes less than 5-minutes to make but it packs all the protein and fiber you need to stay full for hours. It tastes amazing, too, and it uses everyday ingredients you probably already buy regularly.

Here’s how to make these easy oats and some ideas for tasty toppings.

Incredibly easy: Anyone can master this no-cook recipe.

Ingredients

Here’s what you’ll need to make high protein overnight oats:

  • Rolled oats — also known as large flake or old fashioned oats
  • Chia seeds — you could sub ground flaxseed if you want
  • Vanilla protein powder — use any kind you like the taste of
  • Milk — I prefer cow’s milk or soy for the extra protein, but use what works for you

Step-by-step instructions

First, add all ingredients to a mason jar or food container with a lid.

Tips for success

I promise, you can’t mess up these simple overnight oats! But here are a few tips just in case:

  • Use a protein powder you like the taste of
  • For thicker oats, use 1/4 cup less milk
  • For thinner oats, use 1/4 cup more milk
  • Stir the oats well before refrigerating to avoid clumps
  • Stir the oats again before adding toppings to avoid clumps

Topping suggestions

These high protein overnight oats taste best with toppings, and they help add nutrition too.

Here are some of my favorite topping combinations:

  • Peanut butter and jam: 1 cup frozen berries, 1 Tbsp melted peanut butter
  • Banana walnut: 1 sliced banana, 2 Tbsp crushed walnuts
  • Apple cinnamon: 1 chopped apple, dash of cinnamon
  • Trail mix: 2 Tbsp raisins, 2 Tbsp chopped nuts of choice
  • Pear and almond: 1 chopped pear, dash of cinnamon, 1 Tbsp almond butter

Or, use a different flavored protein powder. Chocolate, cinnamon cereal, and salted caramel protein powders are delicious here.

Dietary restrictions

  • Gluten-free: use certified gluten-free oats
  • High fiber: add another tbsp of chia seeds
  • Dairy-free: use soy milk and a plant-based protein powder

What’s the best protein powder for overnight oats?

The best protein powder is the one you enjoy the taste of! I also recommend choosing one that’s been third-party tested for your safety.

If you can tolerate it, whey protein powder is well-studied for muscle growth and I find it has the best texture. I like the whey protein powders from Leanfit (we get them from Costco) and anything from Legion.

If you’d prefer a plant-based protein powder, there are a lot of great options on the market. I’d recommend you choose one with a blend of plant-based proteins, and a brand you enjoy the taste of.

Frequently asked questions

Can I eat these warm?

Yes! To enjoy these protein overnight oats warm, simply heat in the microwave in 30-second intervals before adding toppings. Stir between microwave cycles to prevent burning.

Can I use plant-based milk?

You can use plant-based beverages like almond, cashew, and oat milk if you prefer them. I prefer soy milk for a plant-based option because it contains substantially more protein than other varieties.

How can I add more fiber?

Add an extra tbsp of chia seeds and top with high-fiber berries like raspberries or blackberries.

Help! My oats are too thick.

If you prefer thinner overnight oats, add an extra 1/4 cup of milk before refrigerating.
