In the Bucovina region of northern Romania, hribi cu smântână brings the earthy flavor of porcini together with dairy, eggs and dill. The name means porcini with sour cream, but the documented preparation is more than a quick pan sauce: the softened mushrooms are combined with an egg and sour-cream mixture and finished in the oven. The top turns lightly golden while the center sets into a tender, spoonable casserole.
Regional recipes describe a practical home dish rather than a single regulated formula. The version used here follows a Bucovina account listing one kilogram of porcini, butter, a glass of sour cream, four eggs, chopped dill and salt. A second Romanian account confirms the same central combination and baked finish. The sources leave some measurements open, so this tested-style editorial record defines the glass as 250 ml and gives a usable oven setting and safety endpoint. Those choices make the dish reproducible without claiming every family measures it the same way.
Porcini, also called ceps, have firm stems, broad caps and a deep woodland aroma. Choose fresh mushrooms from a reputable food retailer, with firm flesh and no slimy or damaged areas. This recipe is written for porcini identified and sold as food; it does not ask readers to forage or identify wild mushrooms from photographs. Brush away loose soil and trim the ends. If they need rinsing, do it briefly and dry them well so excess moisture does not dilute the butter and cream.
Cut the cleaned mushrooms into even bite-size pieces so the stems and caps soften at a similar pace. Melt the butter gently in a broad skillet, then add the porcini and cook until they begin to soften. They release moisture as they heat. The regional method adds small splashes of hot water during cooking; add only enough to keep the pan from drying or catching, allowing each addition to cook away before adding more. The source gives no fixed water amount, so the ingredient list intentionally leaves it to need.
The creamy mixture is straightforward: beat the eggs with sour cream, chopped dill and salt, then fold in the cooked mushrooms. A 250 ml measure stands in for the source’s unspecified glass of cream. The four eggs give the mixture structure as it bakes, while sour cream keeps the texture moist and gives it a gentle tang. Use plain cultured sour cream. Salt is listed to taste because the regional accounts do not give a weight and dairy brands vary.
Transfer the mixture to an oven-safe dish and bake at 180°C / 350°F until the surface is lightly browned and the center has set. The Romanian recipes give a short bake of about 10–15 minutes, but they do not specify an oven setting or an egg temperature. This record estimates 15–20 minutes in a preheated oven and uses 160°F / 71.1°C at the center as the safety endpoint for an egg casserole. Ovens and dish depth differ, so begin checking near the lower end and continue in short intervals if needed.
Serve the casserole warm, with mămăligă alongside as the Bucovina accounts recommend. The polenta is a serving accompaniment and is not included in the ingredient quantities or four-serving yield. Let the dish stand briefly after baking so it settles enough to portion. The browned surface, creamy interior and substantial mushroom pieces make it suitable as a main course with a simple salad or as one part of a larger regional meal.
The recipe is best soon after baking, when the porcini remain distinct and the top is newly golden. Cool leftovers and refrigerate them within two hours in a covered container; use within three to four days. Reheat portions until steaming hot throughout, reaching 74°C / 165°F, and avoid repeated cooling and reheating. The original sources do not describe a make-ahead or freezing method, so the guidance here is limited to safe refrigeration and reheating.
