How long can mac and cheese stay fresh in the fridge?

I made mac and cheese a few days ago and forgot about it in the fridge. I’m not sure if it’s still good to eat or should be thrown out. How many days is it safe to keep mac and cheese refrigerated?

So, mac and cheese in the fridge, huh? Generally speaking, it’s good for about 3-5 days if stored properly in an airtight container. BUT… a “few days ago” sounds ominous, like we’re teetering on the edge of the fifth day or maybe even risking Day 6. At that point, you’re entering the danger zone, my friend.

Here’s the deal: if it smells funky, has changed colors, or developed that signature science project fuzz (aka mold), just let it go. No mac and cheese—no matter how delicious—is worth playing gastrointestinal roulette. Even if it LOOKS okay, foodborne bacteria don’t always announce themselves; they’re sneaky like that.

Next time, maybe throw a little date label on there (trust me, your future self will thank you). For now, if you’re unsure, just toss it. Your stomach and dignity are worth more than a questionable leftover.

Mac and cheese in the fridge for ‘a few days’? That’s flirting with danger right there. Sure, @jeff gave the 3-5 day range, but let’s break it down further since food safety doesn’t do well with guesswork. If it’s closer to Day 3, you’re likely fine—assuming you stashed it in an airtight container and your fridge is below 40°F. But past Day 5? You’re betting your digestive system won’t revolt.

Here’s the kicker, though: just because it looks normal doesn’t mean it’s safe. Bacteria are sneaky little jerks. Listeria and friends don’t exactly wave red flags. Don’t just sniff it, either, because some spoiled food doesn’t smell. And if it’s developing a slimy texture? Hard pass.

A hack for the future—label those leftovers! Slap a piece of tape with the date on that container as soon as you pack it up. Future you will love that easy decision-making. For now? Toss it if there’s even a whisper of concern. Trust me, no one wants a mac and cheese regret story.
