Method
Prepare the pan and pasta
- Heat the oven to 375°F.
- Lightly grease a 9x13-inch baking dish with 1 teaspoon olive oil.
- Bring a large pot of water to a boil, add the kosher salt and macaroni, and cook until 2 minutes shy of the package’s al dente time.
- Drain the pasta and set aside.
Cook the shrimp
- Heat 1 tablespoon olive oil in a 12-inch skillet over medium-high heat.
- Sprinkle the shrimp with paprika.
- Cook the shrimp in batches for 1–2 minutes per side, until opaque and 145°F, then transfer to a plate.
Make the cheese sauce
- In the pot used for the pasta, melt the unsalted butter over medium heat.
- Whisk in the flour and cook for 1 minute, whisking constantly.
- Gradually whisk in the milk, dry mustard, and black pepper.
- Cook, whisking often, for 6–8 minutes, until the sauce thickens and bubbles gently.
- Remove the sauce from the heat and stir in both cheeses until melted.
Assemble and bake
- Fold the macaroni and cooked shrimp into the cheese sauce.
- Transfer the mixture to the prepared baking dish.
- Stir the panko with the melted butter.
- Sprinkle the panko mixture evenly over the macaroni and cheese.
- Bake for 15–18 minutes, until the edges are bubbling and the topping is golden brown.
- Rest for 5 minutes before serving.
Notes
For the best texture, cook the macaroni until 2 minutes shy of the package’s al dente time so it finishes in the oven. Refrigerate leftovers for up to 3–4 days; freezing is possible, though the sauce may become less creamy. For a gluten-free swap, use gluten-free macaroni, flour, and panko.
