Night before:
1 1/2 c. steel cut oats
4 c. water
1/2 tsp. salt
Bring water to a boil. Add oats and salt and cook for 1 minute. Remove from heat, cover, and leave overnight.
In the morning:
1 c. milk
1/2 tsp. vanilla
1/4 c. brown sugar
Reheat oats over medium heat, adding in milk, vanilla, and brown sugar (or any other desired sweeteners or mix-ins). Serves 6-8. This refrigerates and reheats well, so make extra for another easy breakfast!
