At the Fourth Annual 2026 Hummingbird Wholesale March Macness Tournament, this rich and savory Cavatappi Mac & Cheese with Hazelnut–Shallot Crumb rose to the top, winning over a field of seven other creative coworker entries. The dish pairs tender cavatappi pasta with a velvety béchamel-based cheese sauce made from equal parts Gruyère, Fontina, and Creamy Toscano soaked in Syrah, with a hint of French onion flavor woven throughout. It’s finished with a crunchy topping of buttery toasted panko, roasted hazelnuts, cashews, and crispy fried shallots, plus a final dusting of grated Toscano rind for extra depth. The result is a bold, layered mac and cheese that balances creamy richness with nutty crunch—earning it the title of 2026 March Macness Champion.
Ingredients
Pasta
-
1 lb Cavatappi Pasta
-
6 quarts water
-
1–2 Tbsp Celtic sea salt
Cheese Sauce
-
1 batch béchamel sauce (prepared without mustard, garlic, panko, hot sauce, cheddar, or added salt)
-
½ packet French Onion Soup Mix
-
1½ Lbs cheese total, grated, in equal parts: Gruyère, Fontina, Toscano soaked in Syrah (rind removed)
Crumb Topping
-
1 c plain panko breadcrumbs
-
2–3 Tbsp butter
-
¼ c roasted hazelnuts, roughly chopped
-
¼ c cashews, roughly chopped
-
¼ c crispy fried shallots
-
Sprinkle French Onion Soup Mix
-
Rind from the Toscano soaked in Syrah, finely grated
Directions
Preheat the Oven to 350° F.
Bring 6 quarts of water to a rolling boil in a large pot. Add Celtic sea salt.
Add the cavatappi and cook until al dente, about 7 minutes.
Drain the pasta and rinse with cold water to stop the cooking. Set aside.
Prepare the Cheese Sauce. Make the béchamel sauce following your preferred recipe, omitting any mustard, garlic, panko, hot sauce, cheddar, or additional salt. Stir ½ packet French Onion Soup Mix into the sauce.
Remove the sauce from heat and stir in 1½ pounds grated cheese (equal parts Gruyère, Fontina, and Toscano soaked in Syrah). Mix until fully melted and smooth.
Assemble the dish. Place the cooled pasta in a 9 × 13 inch glass baking dish. Pour the cheese sauce over the pasta and gently stir to coat evenly.
For the Crumb Topping, in a skillet over medium heat, toast the panko in butter until golden brown. Watch carefully to avoid burning.
Stir in the hazelnuts, cashews, crispy fried shallots, and a light sprinkle of French onion soup mix. Spread the crumb mixture evenly over the pasta. Finely grate the Toscano rind over the top.
Bake at 350°F until the topping is golden brown and the cheese has melted into the crust, about 10–15 minutes. Watch closely as the topping browns quickly.
Remove from oven. Let rest for a few minutes before serving. Enjoy warm.
