Tuna Mac and Cheese Bake

Second week of high school and I was settling in the way water settles — finding the level, filling the available space. The magnet program had a density to it that I appreciated. Teachers moved fast and expected you to keep up, which meant the students who were there wanted to be there, which meant conversations in the hallway could be substantive without apology. I had not known how much I needed that until I had it.

I met two people who would become important: Marcus, who sat next to me in Honors Biology and had strong opinions about everything but knew enough to back them up; and Tanya, from my English class, who wrote poetry in her notebook between assignments and had the most precise vocabulary of anyone I had ever met who wasn't a teacher. I started eating lunch with both of them by Wednesday. By Friday it felt like a given.

In Biology we started the year with cell biology, and I was grateful for the LSU program: the summer research had given me a context that made the textbook content feel like revision rather than introduction. I answered a question in class that surprised Mr. Davenport — he paused and then said, "How do you know about reaction rate variability?" I mentioned the summer program. He wrote something down. I tried not to feel too pleased with myself and mostly failed.

At home that week, I was in a cooking phase that Mama described as "compensating for the cafeteria with ambition." She wasn't wrong. I made stuffed mirlitons one evening — the squash halved and scooped out, filled with a mixture of sautéed shrimp and crabmeat and breadcrumbs and herbs, baked until golden. MawMaw Shirley's recipe, which I have been slowly memorizing the way you memorize a language: repetition and immersion and time. The mirlitons came out beautifully and I ate two of them standing over the counter before I called anyone to the table.

Daddy asked what got into me and I said the cafeteria food was purely motivational. He laughed and said that was exactly how some of the best cooks in Louisiana got their start: cooking in spite of something mediocre. I wrote that down. There is wisdom in everything if you listen.

The stuffed mirlitons that week were MawMaw Shirley’s territory — reverent, practiced, earned. But the cooking energy that kept spilling out of me that whole first week of high school needed other outlets too, and this Tuna Mac and Cheese Bake became one of them: a baked seafood dish that hits those same warm, savory notes without requiring the patience of a Sunday afternoon. It’s the kind of recipe that proves Daddy’s point — that something mediocre nearby can push you toward something genuinely good at home.

Prep Time: 15 minutes | Cook Time: 30 minutes | Total Time: 45 minutes | Servings: 6

Ingredients

12 oz elbow macaroni
2 cans (5 oz each) albacore tuna in water, drained and flaked
3 tablespoons unsalted butter
3 tablespoons all-purpose flour
2 cups whole milk
1 cup chicken broth
2 cups shredded sharp cheddar cheese, divided
1/2 cup shredded Gruyere or Monterey Jack cheese
1 teaspoon Dijon mustard
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
1/4 teaspoon smoked paprika
Salt and black pepper to taste
1 cup frozen peas, thawed
1/2 cup breadcrumbs
1 tablespoon olive oil
2 tablespoons fresh parsley, chopped (for garnish)

Instructions

Preheat and prepare. Preheat your oven to 375°F. Lightly grease a 9x13-inch baking dish with butter or nonstick spray and set aside.
Cook the pasta. Bring a large pot of salted water to a boil. Cook the elbow macaroni 2 minutes less than package directions indicate (it will finish cooking in the oven). Drain and set aside.
Make the cheese sauce. In a large saucepan over medium heat, melt the butter. Whisk in the flour and cook for 1 minute, stirring constantly, until the mixture turns a pale golden color. Slowly pour in the milk and chicken broth, whisking continuously to prevent lumps. Cook for 4—5 minutes, stirring often, until the sauce thickens enough to coat the back of a spoon.
Add cheese and seasoning. Reduce heat to low. Stir in 1 1/2 cups of the cheddar, the Gruyere, Dijon mustard, garlic powder, onion powder, and smoked paprika. Season generously with salt and black pepper. Stir until the cheese is fully melted and the sauce is smooth.
Combine the filling. Remove the sauce from heat. Fold in the drained tuna, thawed peas, and cooked macaroni until everything is evenly coated. Pour the mixture into the prepared baking dish and spread it into an even layer.
Add the topping. Scatter the remaining 1/2 cup of cheddar evenly over the top. In a small bowl, toss the breadcrumbs with olive oil until lightly coated, then sprinkle them over the cheese layer.
Bake until golden. Bake uncovered for 25—30 minutes, or until the top is golden brown and the edges are bubbling. If the breadcrumbs need more color in the last few minutes, switch the oven to broil and watch carefully for 1—2 minutes.
Rest and serve. Remove from the oven and let the bake rest for 5 minutes before serving. Garnish with fresh parsley and serve hot directly from the dish.
