They’re hiding in your fridge door… but some of them should’ve been tossed months ago.
We tend to think of condiments as long-lasting—and while some do have a pretty generous shelf life, others can go bad faster than you’d expect. That half-used bottle of mayo? It might not be as harmless as it looks.
Here are 9 condiments that expire quicker than you think—and how to tell when it’s time to let them go.
1. Mayonnaise
Even refrigerated, mayo can spoil fast due to its eggs and oil. If it smells off or separates, toss it.
2. Pesto
Fridge life: 5–7 days (fresh); 7–10 days (jarred)
Pesto goes bad fast once opened, especially homemade versions. Watch for darkened color or sour smell.
3. Horseradish
Fridge life: 1–2 months after opening
It loses potency quickly—and once the sharpness is gone, it’s basically just bitter mush.
4. Tahini
Fridge life: 1–3 months
Made from ground sesame seeds, tahini goes rancid quickly. If it smells bitter or has an oily film that won’t stir in, it’s past its prime.
5. Salad Dressings (Creamy)
Fridge life: 1–2 months
Creamy dressings like ranch or Caesar have dairy or eggs and spoil more quickly than vinaigrettes. Trust your nose—and the texture.
6. Salsa (Fresh or Jarred)
Fridge life: 5–7 days (fresh); 1 month (jarred)
Salsa is prone to mold, especially once the seal is broken. Look for bubbles, odor, or discoloration.
7. Barbecue Sauce
Fridge life: 1–2 months
It’s easy to forget about that open bottle after grilling season. But the sugar content can ferment over time—so sniff before you slather.
8. Ketchup
Ketchup lasts a bit longer—but not forever. If it starts to taste overly acidic or smells fermented, it’s time to part ways.
