Why You Will Love This Recipe

Fabian’s Budget and Health Tip: Use frozen raspberries when fresh berries cost too much. Stir them in while still frozen. They thaw overnight and release ruby colored juice that sweetens the oats naturally.
Ingredients (Serves 4)
- 2 cups rolled oats (180 g)
- 2 cups raspberries, fresh or frozen (250 g)
- 2 tablespoons ground flaxseed (14 g)
- 2 tablespoons chia seeds (24 g)
- 1 cup plain Greek yogurt (240 g)
- 1 1/2 cups low fat milk or unsweetened plant milk (360 ml)
Step-by-Step Instructions
1. Mix the Oats and Seeds
Add the rolled oats, ground flaxseed, and chia seeds to a large bowl. Stir until the seeds look evenly scattered through the oats, so no spoonful turns too thick later.
2. Stir in the Yogurt and Milk
Add the Greek yogurt and milk. Stir slowly until the mixture looks creamy and loose. It should seem a little thinner than finished oatmeal, because the oats and seeds will drink up the liquid overnight.
3. Fold in the Raspberries
Gently stir in the raspberries. If you use fresh berries, keep a few partly whole for juicy bursts. If you use frozen berries, the mixture may streak pink, which gives the oats a pretty berry swirl by morning.
4. Chill Overnight
Cover the bowl or divide the mixture into 4 jars. Refrigerate for at least 6 hours, or overnight. By morning, the oats should look thick, creamy, and softly pink around the berries.
5. Serve Chilled
Stir each serving before eating. If the oats feel too thick, add a small splash of milk and stir until creamy again. Serve cold, straight from the fridge.
Expert Troubleshooting and FAQs
Can I use frozen raspberries?
Yes. Frozen raspberries work very well. Add them straight from the freezer. They thaw overnight and add extra berry juice to the oats.
Why are my overnight oats too thick?
Chia seeds and flaxseed absorb a lot of liquid. Stir in 1 to 2 tablespoons milk per serving until the oats loosen and turn creamy again.
Why are my overnight oats too runny?
They may need more time in the fridge. Let them chill longer, or stir in 1 tablespoon oats or 1 teaspoon chia seeds and wait 20 minutes.
Can I make this dairy free?
Yes. Use unsweetened plant milk and a plain dairy free yogurt. Choose a thick yogurt for the creamiest texture.
How long do these oats keep?
They keep well in the fridge for up to 4 days. The raspberries soften more each day, so the berry flavor gets stronger.
