Creamy Roasted Butternut Squash Risotto
Slow-stirred Carnaroli or Arborio rice with sweet caramelized butternut squash puree, browned sage butter, dry white wine, and freshly grated Parmigiano-Reggiano.
A classic autumn and winter Italian dish, Butternut Squash Risotto achieves creamy luxury not through heavy cream, but through the mechanical release of starch from high-amylopectin rice gently stirred with simmering hot stock.
This recipe uses a dual-texture method: half of the roasted squash is pureed into silky golden velvet that colors the broth, while the other half is roasted into caramelized cubes folded in at the end for sweet, tender bites.
Finished with the classic mantecatura (vigorous beating of cold butter and Parmigiano-Reggiano off the heat), the risotto flows across the warm plate like gentle lava (all'onda).
Why This Method Works
Dual Squash Preparation
Pureeing half the squash infuses the rice with sweet autumn flavor and golden color, while roasted cubes provide delightful textural contrast.
Hot Stock Additions
Adding simmering hot stock in stages maintains rice starch gelatinization without dropping cooking temperature.
Mantecatura Emulsification
Beating in cold butter and finely grated cheese off the heat emulsifies residual cooking liquid with cheese fat into a glossy sauce.

Creamy Roasted Butternut Squash Risotto
Ingredients
- 1 medium butternut squash (about 2 pounds), peeled, seeded, and cut into 1/2-inch cubes
- 3 tablespoons olive oil, divided
- 1.5 teaspoons kosher salt, divided
- 1/2 teaspoon freshly cracked black pepper
- 5 to 6 cups low-sodium vegetable or chicken broth
- 4 tablespoons unsalted butter, divided
- 12 fresh sage leaves
- 1 medium shallot, finely minced (or 1/2 yellow onion)
- 2 cloves garlic, minced
- 1.5 cups Arborio or Carnaroli rice (do not rinse)
- 1/2 cup dry white wine (Pinot Grigio or Sauvignon Blanc)
- 3/4 cup freshly grated Parmigiano-Reggiano cheese
- Pinch of freshly grated nutmeg
Instructions
-
Roast and Puree the Squash
Preheat oven to 400°F (200°C / 180°C fan). Toss diced squash on a baking sheet with 2 tablespoons olive oil, 1/2 teaspoon salt, and pepper. Roast for 25 minutes until tender and caramelized at edges. Transfer half of the roasted squash to a blender with 1/2 cup warm broth and blend until silky-smooth; reserve remaining roasted cubes.
Texture Cue Squash puree is silky; reserved cubes are tender with golden edges. -
Keep Stock Hot & Crisp Sage
Pour remaining broth into a saucepan and keep on low simmer. In a wide 12-inch heavy skillet or Dutch oven, melt 2 tablespoons butter over medium heat. Add sage leaves and fry for 1 to 2 minutes until crisp. Remove sage with tongs to a paper towel and leave aromatic sage butter in skillet.
Visual Cue Sage leaves crisp up and turn dark green; butter is lightly browned. -
Toast the Rice (Tostatura)
Add remaining 1 tablespoon olive oil to the sage butter. Add minced shallot and cook for 3 minutes until soft. Add garlic and cook 1 minute. Add unrinsed rice and stir constantly for 2 to 3 minutes until grains are coated and edges turn translucent with a faint toasted aroma.
Texture Cue Rice grains make a crackling sound as they toast in the fat. -
Deglaze with Wine (Sfumare)
Pour in dry white wine. Stir constantly until wine is almost completely absorbed by the rice.
Visual Cue Wine bubbles vigorously and evaporates, leaving aroma behind. -
Add Broth and Squash Puree
Stir in the blended butternut squash puree. Begin adding hot broth one ladleful (about 3/4 cup) at a time, stirring frequently. Allow each addition to be mostly absorbed before adding the next ladle. Continue for 18 to 20 minutes until rice is creamy and al dente (tender with a slight firm core).
Texture Cue Velvety, flowing consistency; grains are plump and al dente. -
Mantecatura (Emulsify)
Remove skillet from heat. Stir in reserved roasted squash cubes. Vigorously beat in remaining 2 tablespoons cold butter and grated Parmigiano-Reggiano with a wooden spoon for 1 minute. Add a pinch of nutmeg and season with remaining salt and pepper. Cover and let rest 2 minutes.
Visual Cue Risotto ripples softly when skillet is gently shaken (all'onda). -
Garnish and Serve
Spoon into warm, shallow bowls. Top with crispy fried sage leaves and extra grated parmesan. Serve immediately.
Texture Cue Luxuriously creamy, sweet and savory, with tender rice grains.

Storage, Reheating & Freezing Guidance
Refrigeration: Refrigerate in a sealed container for up to 3 days.
Freezing: Freezing risotto alters rice texture and is not recommended.
Reheating: Reheat in a saucepan with a splash of broth or water over low heat, or shape cold leftovers into arancini (risotto balls) and fry.
