Ingredients Needed
For the overnight oats base:
- 1 cup old-fashioned rolled oats
- 1 cup unsweetened almond milk
- ½ cup plain Greek yogurt (or dairy-free yogurt)
- 2 tablespoons maple syrup (or honey)
- 1 teaspoon vanilla extract
- ¼ teaspoon almond extract (optional, for extra nutty flavor)
- Pinch of salt
For the blueberry almond topping:
- 1 cup fresh or frozen blueberries
- ¼ cup sliced almonds, toasted
- 1 tablespoon chia seeds (optional, for thickness)
Step-by-Step Instructions
1. Combine the wet ingredients
In a medium bowl or a 16-ounce mason jar, whisk together the almond milk, Greek yogurt, maple syrup, vanilla extract, almond extract (if using), and salt until smooth.
2. Add the oats and chia seeds
Stir in the rolled oats and chia seeds (if using) until fully combined. Make sure all oats are submerged in the liquid.
3. Add blueberries
Gently fold in ¾ cup of the blueberries, reserving the remaining ¼ cup for topping.
4. Refrigerate overnight
Cover the bowl or jar with a lid or plastic wrap. Refrigerate for at least 4 hours, but preferably overnight (8–12 hours), until the oats are soft and creamy.
5. Serve and top
In the morning, stir the oats well. If too thick, add a splash of almond milk to loosen. Transfer to a serving bowl or eat straight from the jar. Top with remaining blueberries, toasted sliced almonds, and an extra drizzle of maple syrup if desired.
Tips for Success
- Use old-fashioned rolled oats — not quick oats (become mushy) or steel-cut (stay too chewy)
- Ratio is 1:1 liquid to oats plus yogurt for extra creaminess
- Let oats soak for at least 4 hours; 8–12 hours is ideal
- Toast the sliced almonds in a dry skillet for 3–4 minutes for better flavor and crunch
- For thicker oats, add 1 tablespoon of chia seeds; for thinner, add extra almond milk in the morning
Variations & Substitutions
- Dairy-free / Vegan – Use coconut yogurt or dairy-free yogurt and maple syrup
- Protein boost – Add 1 scoop vanilla protein powder or 2 tablespoons almond butter
- Different fruit – Substitute raspberries, strawberries, or diced peaches
- Warm version – Heat in the microwave for 60–90 seconds for warm oatmeal
- Nut-free – Use oat milk or coconut milk and omit almonds (use pumpkin seeds instead)
- Sugar-free – Use stevia or monk fruit sweetener instead of maple syrup
Serving Suggestions
- Topped with a drizzle of almond butter or peanut butter
- With a side of hard-boiled eggs for extra protein
- Layered in a parfait glass with extra yogurt and berries
- Sprinkled with shredded coconut or cacao nibs
- Served with a hot cup of coffee or matcha latte
Storage & Reheating
Store overnight oats in an airtight container or mason jar in the refrigerator for up to 5 days. The oats will continue to soften and absorb liquid over time. If they become too thick, stir in a splash of almond milk or water before serving. Do not freeze, as the texture becomes grainy upon thawing. These oats are meant to be eaten cold, but you can warm them in the microwave for 60–90 seconds if you prefer hot oatmeal — just stir well before eating.
Frequently Asked Questions
Q: Can I use frozen blueberries?
A: Yes. Add them frozen directly to the jar. They will thaw overnight and release some juice, making the oats slightly purple and sweeter.
Q: Can I make these without yogurt?
A: Yes. Replace yogurt with an additional ½ cup of almond milk. The oats will be thinner but still delicious.
Q: Are overnight oats served cold or hot?
A: Traditionally served cold, straight from the fridge. However, you can microwave them if you prefer warm oatmeal.
Q: How long do overnight oats last in the fridge?
A: Up to 5 days, making them perfect for weekly meal prep.
Q: Can I use steel-cut oats?
A: No, steel-cut oats will not soften properly in cold liquid. Use old-fashioned rolled oats only.
