Cottage cheese casserole is one of those recipes that gets passed down almost unchanged from one generation to the next, and for good reason: it works reliably even for cooks who don’t consider themselves confident in the kitchen. Semolina acts as a natural thickener that keeps the casserole from spreading out too thin, and letting the batter rest before baking is the real trick behind a texture that’s dense but still tender, rather than dry or overly wet.

The quality of the cottage cheese matters more than any other ingredient here. If it’s especially wet, pressing it briefly through cheesecloth helps, otherwise the casserole can turn out denser and need extra time in the oven. Cottage cheese around 5-9% fat gives the most balanced result — fat-free cheese tends to dry the casserole out, while very rich cheese makes it heavier and less airy.

The sour cream layer on top isn’t just about flavor — it’s a practical trick that browns nicely in the oven, gives the casserole an attractive golden top, and helps keep it from drying out. Raisins can be swapped for chopped dried apricots or prunes, or left out entirely without hurting the result.

Serve the casserole slightly warm or fully cooled, since it holds together and slices more neatly that way. It pairs well with sour cream, jam, or condensed milk, and keeps just as well the next day if stored covered in the fridge.
