The cheese is critical here. Sharp cheddar from a block melts smoother than pre-shredded (which has anti-caking agents). Sargento or Tillamook are reliable brands. For the tuna, wild-caught in water gives the cleanest flavor—Bumble Bee or StarKist work well. The milk should be whole for that ultra-creamy texture (trust me on the full-fat version).

No sharp cheddar? Gruyère or Monterey Jack melt beautifully. Want more depth? Add 1/4 cup cream cheese to the sauce. For the topping, panko breadcrumbs give extra crunch. If you’re out of Dijon, regular mustard at half the amount works. The pasta can be any short shape—cavatappi or shells hold sauce well too.

This bakes best fresh but leftovers keep 3-4 days in the fridge. Reheat covered with foil at 350°F for 15-20 minutes. Freezes well for up to 2 months—just thaw overnight before reheating.

Step-by-Step Instructions for Baked Macaroni and Cheese With Tuna

This method delivers a creamy, comforting casserole with a perfectly crisp topping every time.

Step 1: Cook the Elbow Macaroni Al Dente

Bring a large pot of salted water to a rolling boil. Add the 12 oz Elbow Macaroni and cook for 1 minute less than the package directions—it should be slightly underdone. This prevents mushy pasta when it bakes later.

Drain the pasta in a colander and return it to the pot. Stir in the 2 cans Canned Tuna (drained well) and 2 tbsp Mayonnaise. The residual heat softens the tuna slightly, and the mayonnaise adds richness without overpowering the dish.

Step 2: Prepare the Cheese Sauce Base

In a separate saucepan, melt 4 tbsp Unsalted Butter over medium heat until it foams. Whisk in the 0.25 cup All-Purpose Flour and cook for 1-2 minutes until the mixture turns a light golden color and smells nutty. This roux thickens the sauce and removes the raw flour taste.

Gradually pour in the 2 cups Whole Milk, whisking constantly to prevent lumps. Cook for 3-4 minutes until the mixture thickens enough to coat the back of a spoon. Stir in the 1 tbsp Dijon Mustard, 0.5 tsp Garlic Powder, 0.5 tsp Onion Powder, 0.75 tsp Salt, and 0.5 tsp Black Pepper.

Step 3: Incorporate the Cheeses and Combine

Reduce the heat to low and stir in the 2 cups Sharp Cheddar Cheese and 0.5 cup Parmesan Cheese until fully melted and smooth. The combination of sharp cheddar and nutty Parmesan creates a deep, complex flavor. Taste and adjust seasoning if needed.

Pour the cheese sauce over the macaroni and tuna in the pot. Fold everything together gently until the pasta is evenly coated. The sauce should be creamy and cling to each piece of macaroni without being soupy.

Step 4: Add the Crispy Topping and Bake

Transfer the mixture to a greased 9×13-inch baking dish and spread it evenly. In a small bowl, mix the 0.5 cup Dried Breadcrumbs with the remaining 2 tbsp Unsalted Butter (melted), then sprinkle this evenly over the top for a golden, crunchy crust.

Bake in a preheated 375°F oven for 20-25 minutes until the edges are bubbling and the topping is golden brown. Let it rest for 5 minutes before serving—this allows the sauce to set slightly for cleaner slices.

Pro Cooking Tips for Great macaroni and cheese with tuna recipe baked

Perfect Pasta Cook

Cook your 12 oz Elbow Macaroni for 1 minute less than package instructions. This ensures it stays firm when baked. I always taste-test a piece—it should have a slight bite in the center.

Roux Right

For the sauce, melt 4 tbsp Unsalted Butter over medium heat before whisking in 0.25 cup All-Purpose Flour. Cook until golden and nutty, about 1-2 minutes. This builds flavor and prevents a raw flour taste. 🌡️

Cheese Melting Magic

Always use freshly shredded sharp cheddar—pre-shredded has anti-caking agents that make the sauce grainy. Stir in your 2 cups cheese on low heat until completely smooth.

Tuna Treatment

Drain your 2 cans Canned Tuna thoroughly and gently fold it in after cooking the pasta. Avoid breaking it up too much so you get nice chunks of tuna in every bite.

Crisp Topping

Mix 0.5 cup Dried Breadcrumbs with melted butter and spread evenly. For extra crunch, broil for the last 1-2 minutes of baking. Watch closely to avoid burning! 🔥

Resting Period

Let your dish rest for 5 minutes after baking. This helps the sauce thicken slightly and makes serving easier. The flavors meld beautifully during this time.
