Add the diced pancetta to a large pot and sauté over medium heat until golden and crisp.
Do not drain the fat — it’s liquid gold.
Add Onion
Stir in the diced sweet onion and cook until translucent with the faintest golden edge. Do not brown.
Season with black pepper and a tiny pinch of salt.
Make the Roux
Add the butter to the pot. Once melted, whisk in the flour and cook 3–5 minutes over medium–medium low, whisking constantly. It should be smooth and bubbly (not browned).
Add White Wine
Pour in the Chardonnay and whisk. It will tighten up and get a little clumpy — that’s exactly what it should do.
Add Half & Half
Slowly whisk in the room-temp half-and-half.
Bring it to just a boil, then immediately reduce to a medium simmer.
Let it simmer 5–10 minutes, whisking often, until thickened.
Add the Cheeses (Sauce Portion Only)
Reduce heat to low and stir in:
10 oz mozzarella
~6 oz white cheddar
1 cup Pecorino Romano
Stir until completely melted and silky.
Taste, then add salt only if needed.
Assemble
Preheat oven to 350°F.
Grease a 9×13 baking dish.
Add the undercooked rotini and pour the cheese sauce over top.
Make the Topping
Mix the panko with the melted butter.
Sprinkle the remaining mozzarella (6 oz), cheddar (~2 oz), and Pecorino Romano (¼ cup) over the pasta.
Add the buttery panko.
Bake
Bake about 30-40 minutes, or until top is browned and cheese is bubbling.
Broil 1 minute at the end for extra crispiness (optional).
