Saute the chopped onion in a medium pot with butter for 4-5 minutes, or until it starts to brown.
2 tbsp. butter, 1 small onion, finely diced
Add the garlic and mushrooms and cook for 7-10 more minutes, until the mushrooms begin to brown.
2 large garlic cloves, minced, 8 oz. baby Bella or crimini mushrooms, sliced
Now, add the wine and cook until it almost completely evaporates.
½ cup white wine
At this point, add the orzo, broth, milk, salt, and pepper and simmer everything together. Stir occasionally and let it cook for about 10 minutes, until almost all of the liquid is gone. Taste, add more seasonings if needed, and serve.
1 cup orzo, uncooked, 1 cup veggie broth, 1 cup whole milk, ½ tsp. sea salt, ¼ tsp. black pepper
