Hint: Making perfect overnight oats is all about nailing the liquid-to-oat ratio. This is crucial for achieving that ideal creamy, but not soggy, texture. A good starting point is a 1:1 ratio of oats to liquid (milk or a combination of milk and yogurt). However, this can be adjusted based on your preference. If you like your oats thicker, use a little less liquid or add some chia seeds. If you prefer them thinner, add a splash more milk in the morning. Mastering the ratio ensures your overnight oats will be delicious every time!

Topping Ideas:

  • Sliced banana
  • Chopped peanuts
  • Chocolate chips
  • Berries
  • Shredded coconut

FAQ

Can I use quick oats in overnight oats?

Yes, you can use quick-cooking oats, but keep in mind that they will result in a softer, mushier texture. I like using a mixture of rolled oats and quick oats.

My overnight oats are too thick, what can I do?

If your oats are too thick, simply add more milk until you reach your desired consistency. If they are too thin, you can add more oats or chia seeds.

Can I eat overnight oats cold or should I heat them up?

These oats are delicious cold, straight from the fridge. However, you can also warm them up in the microwave or on the stovetop if you prefer.
