Storage & Freezing Tips

  • Refrigerator: Store in an airtight container for up to 2 days. Keep the components separate if possible to preserve texture.
  • Reheating: Reheat gently in a skillet on medium-low heat with a splash of olive oil or butter.
  • Freezing: Freezing is not recommended for this dish because ingredients like eggs become soggy, rubbery, or mushy when defrosted.

Frequently Asked Questions

Can I use steel-cut oats instead of rolled oats?▼

Yes, but steel-cut oats take longer to cook (25-30 minutes) and require a higher liquid ratio (3 cups of liquid per 1 cup of steel-cut oats).

Is ground flaxseed better than whole flaxseed?▼

Yes. Ground flaxseed is much easier for your body to digest and absorb the beneficial omega-3 fats and fibers.
