Notes

Notes
Overnight steel cut oats can be refrigerated for up to 1 week or frozen for up to 2 months. To reheat, top desired amount with a few tablespoons of water or milk, then warm in the microwave or in a small saucepan until hot. If the oatmeal is frozen, let thaw overnight in the refrigerator first.
*The ground flaxseed meal I added for a nutritional boost. If you don’t have it or do not wish to add it, simply omit it. You can also substitute
chia seeds
or
hulled hemp seeds
