Overnight Oats with Flaxseed

Classic overnight oats are my go-to breakfast for busy mornings, so adding ingredients like flaxmeal or chia seeds is an easy way to boost nutrition. And because they’re mild in flavor, you’ll barely notice them while adding omega-3 fatty acids and fiber to your meal.

Ingredients

For this recipe, you’ll need old-fashioned oats (hold their texture best overnight), your favorite regular or dairy-free milk, Greek or regular yogurt (any flavor), flaxseed, and vanilla.

Ratio of Flaxmeal to Overnight Oats

To achieve the best overnight oat consistency, the ratio is ½ cup old-fashioned oats to 1 tablespoon flaxmeal. Then add milk + yogurt or milk only.

How to Make Flaxseed Overnight Oats

Combine the base recipe in each jar and stir. Then add add-ins now or wait and use them as a topping.
Refrigerate for at least 4 hours or overnight.
Serve them cold from the fridge, or microwave them for 30 seconds.
