Step-by-step
- 1
Prep Your Tuna Casserole
Preheat oven to 375°F and grease a 2-quart or 13x9-inch baking dish with butter. If using egg noodles or pasta, cook in well-salted boiling water until just al dente, then drain and cool slightly. Make your sauce base and prep any aromatics. Flake tuna gently into the sauce to keep some texture. Have your topping ready to add right before baking.

Baking the Casserole
Preheat oven to 375°F and place the assembled casserole on the center rack. Bake 15 to 25 minutes. Start checking at 15 minutes. Done when filling is actively bubbling at the edges and the topping is deep golden brown. Do not rely on time alone — both cues must be met. If the topping browns too fast, tent loosely with foil. If the topping looks pale but the filling is bubbling, broil for 1 to 2 minutes and watch closely. Avoid opening the oven door in the first 12 minutes. Rotate the dish 180 degrees at the halfway point only if your oven has a known hot spot.

Doneness and Serving
The casserole is done when the filling bubbles around the edges and the topping is deep golden brown. No internal temperature target is needed since canned tuna is already fully cooked. Rest for at least 5 minutes before serving so the sauce tightens and portions scoop cleanly. Add any fresh garnishes like lemon zest, dill, or chives after resting to keep them bright.
