Blueberry Lemon Overnight Oats (Fiber & Protein Packed!)
These Blueberry Lemon Overnight Oats are the perfect meal prep breakfast. What I love about this Breakfast is that it takes five minutes to stir together at night and then you wake up to a delicious breakfast meal prep that's ready to eat.
I’ve been making this for years when I want something that tastes fresh and light but still filling. It makes great leftovers (hello, 3 servings at once), and it’s easy to switch up with different fruit depending on the season.

Substitutions and Variations
Use a different milk: Almond milk, oat milk, or dairy milk all work.
Swap fruit: Try raspberries, strawberries, or mixed berries.
Make it vegan: Use dairy-free yogurt and maple syrup instead of honey.
Make it sweeter: Add an extra drizzle of honey before serving.

Tips and Notes
The oats will thicken significantly overnight, adjust consistency with milk in the morning.
Frozen blueberries naturally release juice, giving the oats a beautiful purple color.
