Risotto Con Radicchio, Gorgonzola, Noci, e Crema di Balsamico

Step 1
Bring vegetable stock to a boil in a saucepan; reduce heat to low and keep simmering.

Step 2
Heat 2 tablespoons olive oil in a stockpot over medium heat; cook and stir carrot, celery, and onion until onion is translucent, about 2 minutes. Add remaining 2 tablespoons olive oil; stir in rice. Cook and stir until rice is coated with oil and warm, 1 to 2 minutes. Pour in red wine and stir until rice is coated and wine is absorbed, 2 to 3 minutes.

Step 3
Pour 1 ladleful of warm vegetable stock into the rice mixture; cook, stirring continuously, until stock is absorbed, 2 to 3 minutes. Continue adding stock, 1 ladleful at a time, cooking and stirring after each addition until liquid is absorbed and risotto is easily broken when chewed, 10 to 15 minutes.

Step 4
Stir radicchio, Gorgonzola cheese, and walnuts into risotto until cheese is completely melted, 2 to 3 minutes. Add more stock and cook until risotto is tender yet firm to the bite, about 5 minutes more. Remove from heat and cover stockpot for 1 minute.

Step 5
Spoon risotto onto plates and top with balsamic glaze and Parmigiano-Reggiano.
