Cooking Guide

How do I get crispy edges on the baked macaroni?

Baking the mac and cheese at a high temperature on a rimmed sheet pan allows the cheese sauce to bubble and brown, creating crispy, flavorful edges.

Can I substitute the Brussels sprouts with other vegetables?

Yes, vegetables like broccoli or cauliflower work well roasted alongside the macaroni for a similar texture and flavor balance.

What cheeses provide the best flavor balance?

A combination of sharp cheddar and Gruyère offers a rich, nutty flavor and smooth melt, enhancing the sauce's creaminess.

How do I make the cheese sauce thick and smooth?

Whisking butter and flour to form a roux before gradually adding milk ensures a smooth base that thickens gently before adding cheese.

Are there tips for roasting Brussels sprouts evenly?

Toss them well in olive oil and spread in a single layer on the sheet pan to ensure even caramelization during baking.

Can this dish be made gluten-free?

Yes, use gluten-free pasta and substitute panko breadcrumbs with gluten-free alternatives to accommodate dietary needs.
