Preparation
Step 1
How do you cook buckwheat with mushrooms and onion? Prepare the ingredients listed. In this recipe the buckwheat cooks together with the mushrooms, but you can also make this dish using already cooked buckwheat. I use fresh champignons; you can use frozen, dried, or any wild mushrooms you like. For seasoning I use only salt and ground black pepper, but you can add other spices or blends. Prepare a deep skillet with a lid.
Step 2
Sort through the champignons and rinse under cold running water to wash off any dirt and debris. Cut the mushrooms as you like - into cubes or slices. Peel the onion and dice it into small cubes.
Step 3
Place the skillet on the heat and pour in vegetable oil. Add the chopped onion to the hot oil and sauté for a few minutes, stirring constantly so it doesn’t burn.
Step 4
Add the mushrooms to the onion and sauté over high heat until the liquid evaporates (8-10 minutes). Lightly salt the mushrooms.
Step 5
Pick through the buckwheat to remove any debris (sand, husks, dark stones, damaged kernels, etc.). Rinse the buckwheat several times under cold water. Add the rinsed buckwheat to the skillet, season with salt and pepper to taste, and sauté the buckwheat with the mushrooms over medium heat for a couple of minutes.
Step 6
Add boiling water so it completely covers the buckwheat. Reduce the heat, cover the skillet with a lid, and cook for about 15-20 minutes (adjust to your stove). Then turn off the heat and let the buckwheat with mushrooms stand, covered, for another 10-15 minutes.
Step 7
Serve the cooked buckwheat with mushrooms hot. It works as a stand-alone dinner dish, but it can also be a side for meat dishes. When serving, sprinkle with chopped fresh dill or parsley.
