Recipe Q&A

How can I get crispy Brussels sprouts in this dish?

Toss Brussels sprouts with olive oil, salt, and pepper before spreading on the sheet pan to roast. Ensure even spacing for proper caramelization and crispness.

Can I substitute the cheeses used?

Yes, Gruyère can be replaced with fontina or Monterey Jack for a similar melt and flavor profile.

Is there a gluten-free option for this preparation?

Use gluten-free pasta and gluten-free panko breadcrumbs to make the dish gluten-free while maintaining texture.

What enhances the cheese sauce flavor?

Adding Dijon mustard, garlic powder, and smoked paprika enriches the cheese sauce, giving it a balanced, savory depth.

How do I avoid the pasta becoming mushy when baking?

Cook macaroni slightly less than package instructions to keep it firm, as it will continue to cook in the oven.
