MacAroni & Cheese with Tuna

Tuna mac and cheese gets a sophisticated upgrade with diagonally sliced celery, pimento-stuffed green olives, and a wine-spiked sour cream sauce. The pasta and tuna are familiar comfort, but the brininess of olives and the dry white wine cut through the richness and keep it from reading as childish.

Layering is the key technique. Half the macaroni goes down first, half the tuna-cheese mixture on top, then repeat. This stratification ensures every fork brings up both pasta and tuna in every bite, instead of separating into a layer cake.

The sauce is a quick mornay variant: butter and flour cook into a roux, sour cream and wine stir in for a tangy, glossy finish. The acid in both the sour cream and wine balances all that American cheese, keeping the dish bright instead of cloying.

Grated onion (not chopped) is the small detail that matters. It melts into the tuna mixture and disappears, leaving behind onion flavor without crunchy bits competing with the textures.

Foil-covered baking for the first 30 minutes keeps the casserole moist, then uncovering for the last 15 lets the top brown.

Pro Tips

• Drain the tuna thoroughly. Wet tuna waters down the sauce and dilutes the cheese flavor.
• Pat the green olives dry too, brine introduces extra salt and water.
• Stir the roux constantly until smooth and bubbly. Lumpy roux makes lumpy sauce.
• Let it rest 10 minutes before serving. The sauce thickens as it cools and won’t run on the plate.

Variations

• Sub canned salmon for tuna for a different fish flavor profile.
• Use sharp cheddar instead of American for a stronger cheese punch, accepting a slightly less smooth sauce.
• Add 1 cup of frozen peas with the tuna for color and sweetness.
