How Long Does Pudding Last?
Homemade or prepared pudding lasts 3–4 days in the fridge, covered. An opened store-bought pudding cup should be eaten within 2 days. Unopened dry pudding mix keeps about 1 year in the pantry.

Pudding is a milk-based dessert thickened with starch or eggs, made from scratch, from an instant or cook-and-serve mix, or bought in ready-to-eat cups. Milk, sugar and moisture make prepared pudding a highly perishable food that must stay refrigerated. Only the dry mix and sealed shelf-stable cups belong in the pantry.
How to store pudding
- Press plastic wrap directly onto the surface of warm pudding before chilling it. This prevents a rubbery skin and keeps out fridge odors.
- Refrigerate cooked pudding within 2 hours, in a shallow dish so that it cools quickly all the way through.
- Check where you bought the cups: those from the refrigerated case must stay cold, while shelf-stable cups from the grocery aisle only need the fridge after opening.
- Spoon out servings with a clean spoon instead of eating from the bowl, because saliva breaks down the starch and makes leftover pudding watery.
- Freeze pudding in popsicle molds if you have too much. It is good eaten frozen but does not thaw well.
How to tell if pudding has gone bad
- A sour or tangy smell or taste, like milk that has turned.
- Pools of watery liquid with a lumpy or curdled texture. A little clear liquid on day two is normal; heavy separation with an off smell is not.
- Mold on the surface or around the edge of the container.
- A pudding cup with a domed or puffed foil lid, or one that is leaking. Discard it without tasting.
Bacteria that cause food poisoning usually do not change the look, smell or taste of food. Go by the time limits first, and the signs above second.

Frequently asked questions
How long does homemade pudding last in the fridge?
Homemade pudding lasts 3–4 days in the fridge, covered with plastic wrap pressed to the surface. That includes pudding made from instant or cook-and-serve mix, rice pudding and banana pudding. It is made with milk and sometimes eggs, so it needs the same care as other dairy desserts.
Can you eat pudding that was left out overnight?
No. Prepared pudding should not sit at room temperature for more than 2 hours, or 1 hour above 90°F (32°C). Milk-based desserts are an ideal place for bacteria to multiply, and some produce toxins that reheating does not destroy. It may smell and taste normal and still make you sick.
Do pudding cups need to be refrigerated?
It depends on the type. Shelf-stable cups sold in the regular grocery aisle are heat-treated and sealed, so they are pantry-safe until opened. Cups sold in the refrigerated dairy case must be kept cold at all times. Once any cup is opened, refrigerate it and finish it within 2 days.
Are pudding cups still good after the expiration date?
Sealed shelf-stable cups are often fine for a few weeks past their best-by date if the lid is flat and the seal is intact, though the texture may be thinner. Be stricter with refrigerated cups, and do not eat those far past the date. Discard any cup with a puffed lid, a leak, or a sour smell.
Can you freeze pudding?
Not if you want to eat it as pudding. Starch-thickened pudding separates when thawed, turning watery and grainy. It does freeze well as a frozen dessert: pour it into popsicle molds, freeze until firm and eat it within about a month.
