Cook macaroni in salted water according to package directions until al dente. Drain and set aside.
In the same pot, melt butter over medium heat. Whisk in flour and cook for 1 minute until nutty and fragrant.
Slowly whisk in milk. Simmer until the sauce thickens enough to coat the back of a spoon.
Remove from heat and stir in the shredded cheddar until smooth.
Fold in the cooked macaroni, drained tuna, and peas. Use a spatula to stir gently so the tuna stays in visible flakes. For a classic finish, you can top the dish with toasted breadcrumbs.
Add black pepper and garlic powder. Top with a dash of paprika for color.
