Advice
You can use dried mushrooms instead of champignons (you'll need 5–6 times less than fresh). Don't forget to rinse and soak them for 2–3 hours before cooking.
Preparation
Step 1
You can use any mushrooms – wild, champignons, or oyster mushrooms. Boil wild mushrooms beforehand, depending on the type. Wash and peel the vegetables. Sort through the buckwheat to remove black grains and debris.
Step 2
Dice the onion into small cubes.
Step 3
Grate the carrot using a coarse grater.
Step 4
Gently clean the mushrooms from any dirt. Avoid over-wetting them – when soaked, champignons become watery and lose flavor. I wipe them with a damp sponge and dry with paper towels. Slice the mushrooms into thin pieces.
Step 5
Heat a frying pan over medium heat and pour in some vegetable oil. Sauté the onion and carrot for a few minutes while stirring.
Step 6
Then add the mushrooms to the vegetables. Season with salt and pepper, mix. Fry for about 10 minutes, stirring. If using wild mushrooms, fry only after boiling them.
Step 7
Take a suitable ovenproof dish. Rinse the buckwheat several times in cool water. Pour it into the bottom of the dish. Place the sautéed mushrooms and vegetables on top.
Step 8
Pour boiling water into the dish at a 1:2.5 ratio (for every cup of buckwheat, add 2.5 cups of water). Lightly salt the top. Do not stir.
Step 9
Cover the dish with foil and bake in a preheated oven at 180°C (355°F) for 35–40 minutes. The exact time depends on your oven and the amount of buckwheat.
Step 10
After the time is up, remove the dish from the oven – all the water should be absorbed by the buckwheat.
Step 11
Mix the buckwheat with the mushrooms and onions, optionally add some butter, and serve. Enjoy your meal!
