This creamy tuna noodle casserole is a nostalgic, crowd-pleasing comfort food featuring tender noodles, savory tuna, a rich homemade sauce, and a buttery, crispy breadcrumb topping. It’s quick to prepare, endlessly flexible, and perfect for cozy family dinners or potlucks.
For gluten-free, use gluten-free noodles and breadcrumbs. Dairy-free swaps include plant-based milk, vegan cheese, and dairy-free butter. Add extra veggies like mushrooms or carrots for variety. Prep ahead by assembling the casserole (without topping) and refrigerating up to 24 hours; add topping and bake before serving. Leftovers reheat best with a splash of milk. Freezes well for up to 2 months.
