Story of the Dish
These Piedmont-inspired stuffed onions combine slow-roasted onions, sausage, Toma Piemontese, Parmigiano Reggiano and Grissini Torinesi. The grissini are softened inside the filling to retain moisture and kept coarse on top to form a deeply golden crust. The onion should become sweet and tender enough to cut with the side of a fork.
Servings: 4 Prep Time: 35 minutes Cooking Time: 55 minutes Total Time: About 1 hour 30 minutes
Ingredients
For the Onions
4 large yellow onions, 10 to 12 oz each (285 to 340 g) 1 tablespoon extra virgin olive oil 1 tablespoon unsalted butter Fine sea salt and black pepper
For the Filling
12 oz Italian sausage, casings removed (340 g) 4 oz plain Grissini Torinesi (115 g) 3/4 cup whole milk (180 ml) 4 oz Toma Piemontese (115 g), finely diced 1/2 cup finely grated Parmigiano Reggiano (45 g) 1 large egg 2 tablespoons chopped flat leaf parsley 1 tablespoon chopped fresh sage 1/4 teaspoon freshly grated nutmeg Freshly ground black pepper
For the Crust and Cooking
2 oz Grissini Torinesi (55 g) 3 tablespoons Parmigiano Reggiano 1 tablespoon melted butter 1 tablespoon extra virgin olive oil 1/2 cup dry white wine (120 ml) 1/2 cup light chicken stock (120 ml) 4 sage leaves
Preparation
1. Pre-Cook the Onions
Heat the oven to 375°F (190°C). Peel the onions, trim the tops and keep enough root to hold the layers. Place in a baking dish with 1/2 cup water, drizzle with oil, cover tightly and bake about 30 minutes.
2. Hollow
Cool until easy to handle. Remove the center layers while leaving two or three outer layers intact. Finely chop about 1 cup of the removed onion for the filling.
3. Make the Panade
Crush 4 oz grissini, add milk and rest 10 minutes until soft.
4. Cook the Sausage
Cook the sausage over medium heat for about 4 minutes, breaking it into small pieces. Add the chopped onion centers and cook another 5 to 6 minutes. Cool slightly.
5. Build and Fill
Mix sausage and onion with softened grissini, Toma, Parmigiano, egg, parsley, sage, nutmeg and pepper. Taste before adding salt. Fill the onions generously without compressing.
6. Add the Crust
Combine coarse grissini with Parmigiano, parsley, melted butter and olive oil. Apply a thin layer to each onion.
7. Roast
Place the onions in a baking dish with white wine, stock and sage around them, never over the crust. Bake uncovered at 375°F for about 25 minutes. Raise to 425°F (220°C) for the final 4 to 5 minutes until deeply golden.
8. Finish the Jus
Transfer onions to warm plates. Reduce the baking liquid until concentrated and whisk in a small knob of cold butter. Spoon around the onion, not over the crust.
Professional Technique
The onion needs two cooking stages. Pre-roasting makes it tender enough to hollow without overcooking the filling later. Hydrated grissini inside retain moisture; dry grissini on top create crunch. One ingredient performs two opposite jobs.
Chef Tips
Choose onions of similar size. Do not remove too many outer layers. Return the chopped centers to the filling. Use a clean, simply seasoned sausage and a Toma that melts well. Toasted hazelnuts can be added sparingly to the topping.
Common Mistakes
Raw onions from the start: filling finishes before the onion softens. Over-hollowing: the shell collapses. Dry grissini inside: make the filling heavy. Overworking sausage: creates a compact texture. Sauce over the crust: destroys crispness.
Wine Pairing
Barbera d'Asti is the strongest pairing. Dolcetto d'Alba works with toasted grissini and sausage. Nebbiolo d'Alba suits a richer cheese finish. Grignolino d'Asti is lighter. Roero Arneis is excellent when served as an antipasto.
Storage and Reheating
Refrigerate cooked stuffed onions up to 3 days. Reheat at 350°F (175°C) for about 15 minutes and finish uncovered to restore the crust. They can be filled up to 12 hours ahead; add the grissini topping only before baking.

Chef Gianluca’s Recommendation
Keep the filling loose and juicy while pushing the grissini in the opposite direction on top: dry, coarse, toasted and crisp.
