Overnight oats are a miracle of meal prep. But like all miracles, they have limits. Three to five days in the fridge, max. Use your nose, your eyes, and a little common sense. And if you’re still unsure? Toss it. A fresh batch costs a dollar; a trip to urgent care costs more.
Oh, and that mason jar from last Tuesday? It’s now in the compost. I gave it a proper funeral and a eulogy. The moral? Don’t trust your oats when they start smelling like a cocktail bar. Now go make a jar that actually makes it to breakfast tomorrow.
