I grew up thinking stroganoff was one of those dishes that just couldn't work in a kosher kitchen. The traditional version relies heavily on beef and sour cream together, which obviously doesn't fly when you're keeping kosher. But after years of experimenting, I've cracked the code on a mushroom version that's every bit as satisfying as the original. The key is building layers of umami flavor with different types of mushrooms. I use a mix of cremini and shiitake because they each bring something different to the table. The cremini give you that classic mushroom flavor we all know, while the shiitake add this deep, almost meaty richness. You'll want to slice them thick, about half an inch, so they don't disappear into the sauce. What makes this stroganoff work so well is the technique I use for the cream sauce. Instead of dairy, I build the base with a good vegetable stock and finish it with cashew cream or a quality non-dairy sour cream alternative. The cashew cream blends smoother and tastes more neutral than most store-bought options. If you're making your own, soak the cashews for at least four hours first. This dish hits the table in about 30 minutes, which makes it perfect for weeknight dinners when you want something that feels special but doesn't require hours of prep. I like serving it with some steamed broccoli or a simple green salad. The richness of the stroganoff balances nicely with something fresh and crisp on the side.
