Ingredients
Here’s what you’ll need to grab at the grocery store to make this recipe:
- Old-fashioned rolled oats: Don’t use quick oats in overnight oats! They’ve been partially cooked and will turn out mushy in this recipe. Be sure to use old-fashioned rolled oats.
- Also, be sure to use certified gluten-free oats if you have an allergy or sensitivity!
- Unsweetened almond milk: Use your favorite cow’s milk, soy milk, oat milk, pea milk, or any other milk you have. However, the amount of calcium and protein in each milk varies.
- Collagen peptides or any other protein powder: Collagen is an awesome source of protein, and it’s known for its health benefits. I recommend using a brand of collagen that’s grass-fed, like Vital Proteins. Choose a protein powder that complements your flavor preferences, like vanilla or chocolate.
- Peanut butter: Creamy peanut butter creates the best texture for this recipe, but feel free to use the crunchy version if that’s what you prefer!
- Chia seeds: Chia seeds add a wonderful texture as well as extra fiber and protein to help keep you full longer.
- Maple syrup: Be sure to use real maple syrup and not pancake syrup. Always check the label.
Substitutions and variations
Protein powder: Feel free to swap the collagen peptides for vanilla protein powder, chocolate protein powder, or your favorite flavor.
Nut butter: Not a fan of peanut butter? No problem! You can substitute the peanut butter with almond butter, sunflower seed butter, or any other nut butter of your choice for a different flavor.
Sweetener: Replace maple syrup with honey or agave syrup if preferred.
Toppings: Add your favorite toppings and mix-ins! Stir in mini chocolate chips, chopped nuts, diced strawberries, bananas, or whatever you’d like!
Vegan: To make this recipe vegan or dairy free, be sure to use a vegan-friendly protein powder and a vegan-friendly milk substitute.

Instructions
First, measure and add the oats, almond milk, maple syrup, chia seeds, peanut butter and collagen peptides to two wide-mouth mason jars or similar containers with lids.
Use a spoon to fully mix all the ingredients well. Cover the jars and set them in the refrigerator for 6-8 hours or overnight. That’s it!
Store the prepared oats covered in the refrigerator until you’re ready to eat them, up to 4 days in advance. The oats can be eaten right out of the fridge (chilled), or you can warm them in the microwave for 1-2 minutes before serving.
Before you dig in, quickly stir up the oats again! I like to top the oats with some slices of banana or blueberries and a little drizzle of peanut butter, but whatever you like is great!
Want it faster? You don’t have to wait overnight! To cook the oats:
- Microwave one serving at a time, uncovered, for 2 minutes on high.
- Allow it to sit for another 2 minutes.
- Stir and dig in!

How to Serve High Protein Overnight Oats
There are so many ways to enjoy overnight oats! You can eat them straight out of the jar or dump them into a bowl. I love the jar when I'm on the go!
- Fresh fruit: Top with fresh fruit like sliced bananas, berries, or diced apples.
- Crunchy toppings: Add a sprinkle of granola or chopped nuts for added crunch.
- Add drizzles: Add a drizzle of almond butter or maple syrup for extra flavor.
You can do it either way! When I’m in a rush, I grab a jar and eat it right out of the fridge. But if I have a few minutes, I remove the lid and heat up a serving for about 2 minutes in the microwave. It’s totally up to you!
Tips for Success
This incredible High Protein Overnight Oats recipe is just like the real deal. To make it extra succesful, here are a few solid tips:
- Use Old Fashioned Rolled Oats: Quick oats can become too mushy, so stick with old-fashioned oats for the best texture.
- Mix Thoroughly: Make sure all of the ingredients are mixed together well in order to avoid clumps.
- Prep in Advance: These oats can be stored for up to four days in the refrigerator, making them perfect for meal prep!
- Customize the Consistency: Adjust the amount of almond milk to make the oats thicker or thinner to suit your preference.
FAQ
Use between 3/4 cup and 1 cup of liquid for every 1/2 cup of old fashioned rolled oats. The amount you use should depend on the consistency of oats you like. Start with less and you can always stir in a more, a little at a time, until it reaches the consistency you prefer.
Feel free to use flavored or sweetened almond milk if you want. It works well, but just keep in mind that it will add extra sweetness, so adjust the sweetener if needed.
Overnight oats are good for up to 4 days, per USDA. I prep a few jars on Sunday evening and try to eat them by Thursday.
Yes! Oats are healthy whole grains that are a good source of fiber, carbohydrates, and protein, and they contain important vitamins and minerals like manganese, phosphorus, and B vitamins. Paired with collagen, which is a great source of protein, chia seeds, which contain calcium, fiber, and more, this recipe is definitely good for you! However, beware of other overnight oats recipes that call for things like added sugars or artificial ingredients, which have fewer nutritional or health benefits!
Old fashioned rolled oats are the best choice for overnight oats. Avoid using quick oats!
