How long does Kugel last in the fridge?
Turning the range into a date
Kugel (homemade) keeps 3–4 days in the fridge. Each kind gets its own dated rows here, 3 rows across the 2 the USDA lists under this name, because a date is only worth printing against the window it belongs to.

The USDA rates 2 kinds of this separately
The USDA files 2 separate entries under this name — commercial and homemade — and gives every one of them the same window outside the freezer, 3 days to 4 days. They are separate rows in the source rather than separate answers to the question.
Freezing changes the unit, not just the number
Here the freezer does not so much extend the answer as replace it. 4 days in the refrigerator becomes 1 month in the freezer: 7.5 times longer, and days turning into months. It stands 1 of 11 on its shelf, one step below Pizza, frozen at 4 days after cooking. Commercial, commercial kugel and homemade are the same food in the source list.
Every storage figure the USDA publishes for this item
The USDA rates this item cold or frozen and never at room temperature: no pantry figure exists for it, as for 222 of the 466 foods in the data that get no pantry time at all. The source also indexes it as commercial and homemade.

Can you freeze kugel?
Yes. The USDA gives kugel (homemade) 1 month in the freezer, and held at 0 °F food stays safe beyond that: the figure is about quality. Cool it fast in shallow containers first, then freeze it in portions you will thaw in one go.
How to tell if kugel has gone bad
Go by the date first: kugel keeps 3–4 days in the fridge. An off smell, mold or a slimy film mean it goes out, but leftovers can carry harmful bacteria with none of those signs, so the calendar decides first. Never taste to test.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 3 days to 4 days in the fridge. What decides that is the food: the source files Kugel, homemade under Food Purchased Frozen, a heading it keeps for perishable food. Past it, it is not safe to eat: throw it out without tasting, because bacteria build up while food still looks and smells fine.
The figure in the freezer here is a quality window. The same page carries windows of more than one kind, so which sentence applies depends on which row you are reading, not on the food.
It is past the date. Now what?
Say the calculator above puts Kugel, homemade past its 3 days to 4 days in the fridge window, or the container sat out on the counter overnight. Throw the container out without tasting it, and count any hours it already spent out of the refrigerator as part of that window rather than on top of it.
The USDA's limit for perishable food standing at room temperature is 2 hours, or 1 hour when the kitchen is above 90 °F, and that clock runs whatever the storage figure says. Freezing stops the clock but does not turn it back: food already past its window is not rescued by putting it in the freezer. The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.
Items that behave the same way
All 3 of the 3 items nearest Kugel, homemade keep exactly as long as it does, 4 days, so the ranking around it is a tie rather than an order.
Where these numbers come from
Every storage time on this page is the USDA’s own published figure from the FoodKeeper data, one of the 9 it keeps per food, reproduced unchanged and never an estimate of ours. Where the USDA lists several kinds under one name, each kind keeps its own windows, and the page names the kind its answer is for. The dates and multipliers are ours, computed from those ranges.
