Ingredients
For the Pasta and Fish:
12 oz elbow macaroni or short pasta
1 lb white fish fillets (such as cod, haddock, or tilapia)
1 tablespoon olive oil or butter
Salt and pepper, to taste
1 tablespoon lemon juice (optional)
For the Cheese Sauce:
3 tablespoons butter
3 tablespoons all-purpose flour
2 cups whole milk
1/2 cup heavy cream (optional for extra creaminess)
1 1/2 cups shredded sharp cheddar cheese
1/2 cup shredded mozzarella or Monterey Jack
1/4 cup grated Parmesan

Salt and pepper, to taste
For the Topping:

Ingredient Notes
Fish: Use mild, firm white fish. Poach, pan-sear, or bake until flaky. Remove any bones.
Cheese: Sharp cheddar offers depth. A mix of mozzarella or Monterey Jack adds creaminess.
Pasta: Elbow macaroni holds the sauce well, but shells or cavatappi work too.
Breadcrumbs: Panko adds extra crunch. Combine with butter for a golden top.

Instructions
Step 1: Cook the Pasta
Boil a large pot of salted water. Cook macaroni according to package directions until al dente. Drain and set aside.
Step 2: Cook the Fish
Season fish with salt and pepper. In a skillet, heat olive oil or butter over medium heat.
Cook fish for 3–4 minutes per side, or until opaque and flakes easily with a fork.
Flake into bite-sized pieces and set aside. Add lemon juice if desired.
Step 3: Make the Cheese Sauce
In a medium saucepan, melt butter over medium heat. Stir in flour and whisk continuously for 1–2 minutes to form a roux.
Slowly whisk in milk (and cream if using), stirring constantly until thickened—about 5–6 minutes.
Reduce heat to low. Stir in cheddar, mozzarella, Parmesan, garlic powder, paprika, salt, and pepper. Stir until smooth.
Step 4: Combine and Assemble
In a large bowl, combine cooked pasta, flaked fish, and cheese sauce. Stir gently to avoid breaking the fish too much.
Transfer to a greased baking dish.
Step 5: Add Topping and Bake
Mix breadcrumbs with melted butter and Parmesan. Sprinkle over the top of the casserole.
Bake at 375°F (190°C) for 20–25 minutes, until bubbling and golden on top.
Cool for 5 minutes before serving.
Tips
Don’t overcook the fish—it should be just flaky to stay moist in the bake.
Add a handful of peas or spinach to the mix for color and nutrition.
Use smoked fish for a stronger flavor (like smoked haddock or salmon).
Make ahead: Assemble and refrigerate up to 1 day before baking.
Variations
Tuna Mac and Cheese: Use canned tuna in place of fresh fish for convenience.
Spicy Version: Add a dash of cayenne or diced jalapeños to the sauce.
Seafood Mac: Mix shrimp or crab with the fish for a luxurious upgrade.
Herb Crust: Add fresh thyme or parsley to the breadcrumb topping.
