Ingredients

Instructions

  1. Step 1: Rinse 1 cup buckwheat groats under cold water until water runs clear. In a medium pot, bring 2 cups water to a boil, add the buckwheat groats and 1/2 tsp salt, cover, reduce heat to low, and simmer for 15 minutes until water is absorbed and groats are tender.
  2. Step 2: While buckwheat cooks, heat 3 tbsp butter and 1 tbsp olive oil in a large skillet over medium heat. Add 1 medium finely chopped yellow onion and sauté for 5-7 minutes until soft and golden.
  3. Step 3: Add 8 oz sliced button mushrooms and 2 minced garlic cloves to the skillet. Cook for 6-8 minutes until mushrooms release moisture and become browned, stirring occasionally.
  4. Step 4: Stir in the cooked buckwheat groats, season with 1 tsp salt and 1/2 tsp black pepper, and cook together for 2-3 minutes, allowing flavors to meld.
  5. Step 5: Remove from heat and mix in 2 tbsp chopped fresh dill. Serve warm as a side or light main.
