For the Risotto:
1 small butternut squash
4 cups chicken stock
2 tablespoons extra virgin olive oil (plus 1/4 cup for garnish)
3 shallots, chopped
2 cloves garlic
1 tablespoon chopped fresh sage (plus 8-10 fresh leaves for garnish)
1 cup arborio rice
1/4 cup dry white wine
1 tablespoon unsalted butter
Salt and black pepper, to taste
1/2 cup grated Asiago cheese, divided
1/4 cup pine nuts
1/2 cup balsamic vinegar
1 tablespoon brown sugar
Preheat oven to 350-deg.
Combine the balsamic and brown sugar in a small saucepan over medium heat until it reduces in half to a syrupy consistency. Remove from heat and set aside.
Cut squash in half lengthwise. Rub with olive oil and season with salt and pepper. Arrange on a foil-lined baking sheet, cut side down. Prick outside skin a few times with a fork. Roast for 35 to 40 minutes, or until tender. Remove from oven and let cool slightly. Scoop flesh out of skin and purée in a food processor until smooth. Measure out 1 cup of purée and set aside.
Meanwhile, warm chicken stock in a small saucepan set over low heat. Cover and keep warm.
To prepare garnishes, heat 1 tablespoon of olive oil in a very small saucepan set over medium heat. When oil is hot, add pine nuts, stirring until coated with oil. Toast for 2 to 3 minutes or until nuts start to turn golden brown. Keep an eye on them, they can go from toasted to burnt very quickly.
Remove nuts from pan with a slotted spoon and transfer to a paper towel lined plate. Return pan to heat and add remaining 4 tablespoons oil, or enough to form a 1/4-thick layer in the bottom of the pan. When the oil is hot and shimmering, add sage leaves, 2 or 3 at a time (be careful, they will crackle). Cook for about 30 seconds then quickly remove from oil and transfer to a paper-towel lined plate to cool. Repeat with remaining leaves.
Heat olive oil in a large saucepan set over medium heat. Add shallots and garlic and saute until softened and fragrant, 2 to 3 minutes. Add chopped sage and cook for another minute. Add rice and stir until grains are coated and start to turn transparent, about 2 minutes.
Add wine and stir the wine has completely absorbed. Add 1/2 cup of warm chicken stock to the rice, stirring until liquid is mostly absorbed before adding more. Continue to add broth, 1/2 cup at a time, stirring constantly after each addition. After about 15 to 18 minutes, when the rice is almost done, stir in squash purée. Continue to cook until rice is creamy and al dente. Season with salt and pepper.
Finish with butter and 1/4 cup grated Asiago, stirring until fully incorporated. Divide among serving bowls and top with remaining cheese, a drizzle of the balsamic glaze, pine nuts, and sage leaves.
