Ingredients Notes

  • 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.
  • 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. You can substitute any other protein powder you enjoy.
  • You can substitute almond butter or any other nut butter you enjoy.
  • Be sure to use confirmed or certified gluten free oats if you have an allergy or sensitivity!
  • Substitute cow’s milk, soy milk, oat milk, or pea milk or any other milk you have. However, the amount of calcium and protein in each milk varies.
  • To make this recipe vegan, use a vegan friendly protein powder and vegan friendly milk substitute.

Instructions

Step 1: Measure and add the oats, almond milk, maple syrup, chia seeds, peanut butter, and collagen peptides (all the ingredients) to two wide mouth mason jars or any other containers with lid.

Step 2: 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!

Step 3: 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 it, 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:

  1. Microwave one serving at a time, uncovered, for 2 minutes on High. 
  2. Allow it to sit for another 2 minutes. 
  3. Stir and dig in!

FAQ & Tips

What’s the correct oats to liquid ratio?

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.

How long are overnight oats good for?

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.

Should I eat overnight oats cold or hot?

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!

Are overnight oats good for you?

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!

What kind of oats are best for overnight oats?

Old fashioned rolled oats are the best choice for overnight oats. Avoid using quick oats!
