Ingredients and Substitutes

Rolled oats. These provide the hearty base and soak up the liquid overnight to create a creamy texture.
Chia seeds. They help thicken the mixture while adding texture and extra fiber.
Salt. Enhances and balances the sweetness of the oats and fruit.
Liquid sweetener. Adds sweetness. Use honey, maple syrup, agave or what have you. Granulated sweeteners also work if you’re warming up the raspberries before blending.
Milk of choice. Softens the oats and adds creaminess; use any dairy or plant-based milk.
Raspberries. Fresh or frozen, they contribute tartness and natural sweetness.
Lemon juice. Adds brightness and tang to balance flavors. Adjust quantity to taste.

Step-by-Step: How to Make Raspberry Overnight Oats

Mix dry ingredients. Start by adding rolled oats, chia seeds, and a pinch of salt into a bowl or a jar. Give everything a quick stir so the dry ingredients are evenly combined and ready to soak up all the flavors.

Prep raspberries. If you’re using frozen raspberries, let them defrost overnight in the fridge or gently warm them on the stove with a splash of water over low heat. Next, blend fresh or defrosted raspberries with an immersion blender or mash them using a fork until you get a smooth, saucy texture. Then, stir in fresh lemon juice and the sweetener. Taste and adjust the sweetness or tartness to your liking. It’s okay if it’s a bit too sweet at this point, as you’re going to dilute the flavor a bit with milk.

Refrigerate overnight. Cover your bowl or jar with a lid or plastic wrap and pop it in the fridge. Let it chill and soak for at least 6 hours, or overnight, so the oats soften and all the flavors meld.
Top and eat. When you’re ready, take your raspberry overnight oats out of the fridge. Give it a good stir, add your favorite toppings like nuts, seeds, fresh fruit, or a dollop of yogurt, and enjoy.

Variations

Vegan

To make the raspberry overnight oats completely vegan, you will need to make a couple of ingredient swaps:

Use plant-based milk such as oat milk, almond milk, soy milk, or any other dairy-free milk instead of cow’s milk.
Replace honey or any non-vegan sweetener with a vegan liquid sweetener such as maple syrup, agave nectar, or any branded option.

High Protein

To boost the protein content of your raspberry overnight oats without changing the delicious flavor or texture:

Add one portion of vanilla protein powder (about 30 grams total, 20 grams of protein) to the mixture.
Reduce the milk by 2 tablespoons to maintain the same creamy consistency.
Halve the amount of sugar or liquid sweetener to balance the slight sweetness that comes from the vanilla protein powder.

Tips

Stir before eating. Overnight oats tend to settle in the fridge, so give them a good stir to recombine the layers and achieve a consistent texture throughout.
Mix in extra milk if needed. If the oats seem too dense or dry after soaking, add a splash of your preferred milk and stir to loosen the mixture. It’s much easier to fix oats that are too dry than too watery.
Consider granulated sugar. If you’re warming frozen raspberries on the stove, you can use granulated sugar instead of a liquid sweetener. The sugar will easily dissolve in warm puree. You’ll likely need about 3 teaspoons to match the sweetness of 2 teaspoons of liquid sweetener.
