Recipe FAQ

How do I ensure crispy edges on the macaroni?

Use a rimmed sheet pan and spread the macaroni mixture evenly. Baking uncovered at a high temperature helps develop crispy cheese edges.

Can I substitute the cheeses used in the sauce?

Yes, Gruyère can be replaced with fontina or Monterey Jack for a milder taste while retaining creaminess.

What’s the best way to roast Brussels sprouts evenly?

Toss the sprouts in olive oil, salt, and pepper, then spread them in a single layer on half the sheet pan to allow even caramelization.

Is this dish suitable for a gluten-free diet?

To make it gluten-free, substitute pasta and panko breadcrumbs with certified gluten-free alternatives.

How can I add extra flavor to the cheese sauce?

A pinch of chili flakes or smoked paprika can elevate the sauce with subtle heat and depth.
