Instructions

  • Cook pasta according to package instructions; drain.
    10 ounces egg noodles
  • Preheat the oven to 355°F (180ºC).
  • Heat a non-stick skillet and add the olive oil, once it’s hot, fold in the garlic and onion and cook until wilted about 7 minutes.
    2 tablespoons olive oil, 3 cloves garlic, 1 red onion
  • Add the flour, mix well, and cook until slightly thickened, then whisk in the milk until fully combined and continue cooking for a couple of minutes or until desired thickness is achieved.
    3 tablespoons all-purpose flour, 4 cups milk
  • Remove the mixture from heat, then stir in the shredded cheddar cheese until melted and well incorporated. Gently fold in the flaked tuna and season with salt and pepper to taste. Finally, add the cooked noodles and mix thoroughly until everything is evenly distributed.

Notes

  • Tuna: Opt for tuna in water for a lighter casserole, or use oil-packed tuna for a richer flavor.
  • Customize your veggies: Add frozen peas, corn, chopped carrots, or even mushrooms to sneak in some extra veggies.
  • Cheese: While Cheddar is great, try mixing in some mozzarella, Gouda, or Parmesan for a different taste.
  • Crunchy topping alternatives: If you're out of Panko, crushed potato chips or Ritz crackers make a great substitute for a crispy finish.
  • Make it gluten-free: Swap regular noodles for gluten-free pasta and use gluten-free flour to cater to dietary needs.
  • Cooking the roux: Don't rush cooking the flour and fat mixture; let it cook for a few minutes to avoid a floury taste.
  • Add a splash of color: Fresh parsley not only adds flavor but also makes your dish pop with color.

Storage and Reheating Instructions

  • Cool: Let the casserole cool to room temperature before you pack it up. 
  • Refrigerate: Store leftovers in an airtight container in the refrigerator. They'll keep well for up to 3 days.
  • Freeze: You can freeze the casserole either baked or unbaked. If unbaked, add the topping after thawing and before you bake it. It can last in the freezer for up to 2 months.
  • Reheat: To reheat, sprinkle a little water over the top and cover with aluminum foil. Warm it in the oven at 350°F until heated through.
  • Microwave: If you're short on time, you can also microwave portions. Just cover the dish with a wet paper towel to avoid drying out the pasta.
