Ingredients for this Raspberry Overnight Oats Recipe

  • Old Fashioned Rolled Oats: We recommend using old-fashioned rolled oats as they easily absorb the liquid overnight and come morning, provide a smooth and chewy texture. However, if you do not have old-fashioned oats, and you just have quick-cooking oats, you can use but be sure to enjoy them the next day otherwise, they will become too mushy. And finally, we don’t advise using steel-cut oats as the texture of your oats will be extremely dense.
  • Raspberries: During the summer months plump juicy raspberries provide another avenue of natural sweetness but feel free to use frozen if that’s what you have on hand. And regardless, if you’re using fresh or frozen, be sure to reserve some as a tasty garnish for the top of your raspberry oats!
  • Greek Yogurt: For added nutrition and protein, we used plain Greek yogurt. If you need to make these overnight oats with raspberries dairy-free, feel free to use your favorite non-dairy Greek-style yogurt.
  • Milk: Overnight oats can be made with either dairy or unsweetened plant-based milk such as almond, cashew, oat, coconut, or any other favorite.
  • Honey: Used as a natural sweetener, feel free to add more or less based on your taste preference and the sweetness of your raspberries. And to make these vegan, maple syrup would be a delicious substitute.
  • Chia and Flax Seeds: While optional, chia and flax not only add additional nutrients such as fiber and essential fatty acids, but they also help to thicken the oats. Feel free to omit it completely or use one or the other.

FAQ and Expert Tips

What is the best kind of oats for overnight oats?

We recommend using Old Fashioned Oats, regular or gluten-free, as they soften nicely as they absorb the milk overnight and produce a creamy, velvety texture without being mushy. Quick oats (sometimes called instant oats) can be used but do not have as much pleasantly toothsome texture.

Can you add fruit to overnight oats?

Yes, you can add fruit and fresh berries to overnight oats. It is a great way to add fruit to a simple breakfast. Fruit, whether fresh or frozen, will add additional sweetness, fiber, nutrients and flavor to your oats.

Do you eat overnight oats hot or cold?

These oats are meant to be enjoyed cold. Since the oats are soaked overnight, they have a soft, creamy texture, so heating is not necessary. If cold overnight oats are not your thing and you prefer your oats warm you can heat your overnight oats. To warm overnight oatmeal simply transfer it to a microwave-safe bowl and heat in 30-second increments until the desired temperature is reached.

How long do overnight oats last?

Overnight oats can last for up to four days in the refrigerator.

Can I make these raspberry oats vegan?

Raspberry overnight oats can be made vegan. To do so, make these easy swaps: Use pure maple syrup or agave syrup for the honey and use your favorite plant-based milk, like oat milk or almond milk, and Greek-style vegan yogurt.

Can you add frozen raspberries to overnight oats?

While fresh raspberries are plentiful during the summer months, these overnight oats can be made year-round by using your favorite brand of frozen raspberries as they are picked at the height of ripeness and so juicy once thawed! Once the frozen berries are thawed, lightly mash them with the honey and follow the recipe as directed.

Are overnight oats gluten-free?

No, overnight oats are not guaranteed to be gluten-free, unless they are made with certified gluten-free oats. If you have celiac disease or a severe gluten intolerance it is important to check your labels carefully to prevent contamination.

Topping Ideas for Overnight Oats with Raspberries

While we love to finish these easy raspberry chia overnight oats with a handful of raspberries, any of the following would be delicious toppings to round out this healthy breakfast in a mason jar!

  • Top with red strawberries, fresh blueberries, juicy blackberries or sliced bananas instead of extra raspberries.
  • Add a touch of crunch with sliced almonds, walnuts, or even pecans!
  • For a hint of sweetness sprinkle with your favorite chocolate chips or some coconut flakes

Meal Prep Tips

The best part of these raspberry overnight oats is they can be prepped up to 4 days in advance. While these oats can be made in any container, we like to use individual jars, such as mason jars, for convenient individual servings that you can just grab and go on busy mornings. The key is to keep them covered in the fridge and to use raspberries that are free of any signs of spoilage.

Substitutions and Variations to Try

While we love how easy and flavorful this simple raspberry overnight oats recipe is, feel free to customize it to your liking with any of the following suggestions:

  • Add in a 1/2 teaspoon of vanilla extract
  • To amp up the protein content, add a scoop of your favorite protein powder. Use pea protein or hemp protein for plant-based protein if making the vegan variation.
  • Use coconut milk, coconut yogurt and garnish with toasted coconut for a tropical twist
  • When mashing the raspberries with honey, add in a scoop of almond butter or peanut butter for additional nutrition, nuttiness, and creaminess
  • Stir in lemon zest to help brighten up the natural sweetness of the raspberries
  • Don’t have chia or flax on hand? Swap in hemp seeds for the same subtle nuttiness with additional nutritional benefits
