Simple, nutty buckwheat groats simmered soft and finished with browned butter, a traditional Czech side dish and comfort food known as kaše.
Kaše refers broadly to porridge in Czech, but buckwheat kaše specifically holds a place as a traditional side dish and comfort food, valued for its nutty, earthy flavor and its role as a hearty alternative to potatoes or dumplings alongside stews and roasted meats. The buckwheat groats are toasted lightly before simmering, a step that deepens their flavor and helps the grains stay separate rather than turning into a sticky mass. Unlike sweet breakfast porridges, this version is savory, finished simply with browned butter poured over the top just before serving — the nutty aroma of browned butter pairing naturally with buckwheat's own toasty character. Some households also fold in caramelized onion or crisp bacon bits for extra richness, turning a simple side dish into something substantial enough to eat on its own. Getting the ratio of water to buckwheat right, along with not overcooking it, is what keeps the groats fluffy and distinct rather than mushy. Kaše is old, humble food, closely tied to periods of rural Czech and broader Central European cooking when grains were more affordable and available than meat.
Serves 4
Toast dry buckwheat groats in a heavy pot over medium heat, stirring, for 3 minutes until fragrant.
Add water or stock and salt. Bring to a boil, then cover and simmer on low heat for 12 to 15 minutes until the liquid is absorbed and the groats are tender.
Resist stirring too much while it simmers — this keeps the grains distinct rather than turning them starchy and clumped.
Remove from heat and let stand, covered, for 5 minutes, then fluff with a fork.
While the buckwheat rests, melt butter in a small pan over medium heat until it turns golden-brown and smells nutty, 3 to 4 minutes. If using onion, cook it in the butter until deeply caramelized before browning fully.
Pour the browned butter (and onion, if using) over the fluffed buckwheat and serve hot as a side.
Toast the raw buckwheat groats briefly before adding liquid — this step deepens the nutty flavor considerably.
Watch the butter closely as it browns; it goes from nutty and golden to burnt within seconds if left unattended.
Let the buckwheat rest covered off the heat for a few minutes before fluffing — this helps it finish cooking evenly.
Add crisp bacon bits along with the browned butter for a heartier, meatier version.
Serve with fried mushrooms folded through for a vegetarian main course rather than a side.
Sweeten with a little sugar and serve with milk for a breakfast porridge version instead of the savory side dish.
Refrigerate up to 4 days; reheat with a splash of water or stock in a covered pan or microwave, since it firms up considerably once chilled.
Buckwheat kaše is a traditional Czech and broader Central European side dish, historically valued as an affordable, filling grain alternative to potatoes, and it remains a familiar comfort food alongside stews and roasted meats.
They refer to essentially the same dish — buckwheat porridge — with kaše being the Czech term and kasha the more commonly known Russian and Eastern European term for the same toasted buckwheat groats.
You can, but toasting first meaningfully deepens the nutty flavor, so it's worth the extra 3 minutes if you have the time.
It works well as a side to roasted or braised meats, goulash, or mushroom dishes, in the same role potatoes or dumplings would typically play on a Czech plate.
