Ingredients

  • 2 tablespoons chopped fresh chives
  • 2 teaspoons Dijon mustard
  • 1 tablespoon lemon zest
  • 1 tablespoon olive oil
  • 3 cloves garlic minced
  • cup freshly grated Parmesan
  • 10 ounces wide egg noodles approximately 4 ½ cups
  • 3 5-ounce cans tuna in water, drained
  • cup Panko
  • 3 tablespoons unsalted butter
  • 3 ½ cups half and half
  • 2 large shallots diced
  • 1 cup frozen green peas rinsed
  • 2 tablespoons all-purpose flour
  • Kosher salt and freshly ground black pepper to taste
  • 8 ounces shredded sharp white cheddar cheese approximately 2 cups

Instructions

  • In a generously salted pot of boiling water, cook the egg noodles following the package instructions; drain thoroughly and set aside.
  • Preheat the oven to 400°F.
  • In a Dutch oven over medium heat, melt the butter. Incorporate the garlic and shallots, sautéing with frequent stirring until aromatic and softened, about 2 minutes.
  • Whisk in the flour and cook until it develops a light golden hue, approximately 1 minute.
  • Gradually pour in the half and half and add Dijon mustard; stir constantly until the mixture thickens slightly, about 4 to 5 minutes.
  • Remove the pot from heat and blend in the shredded cheddar cheese until the sauce is smooth and fully integrated, roughly 2 minutes.
  • Fold in the drained noodles, tuna, and peas, ensuring the ingredients are evenly distributed; adjust seasoning with salt and pepper as needed.
  • Evenly spread the Panko topping mixture over the casserole.
  • Transfer the Dutch oven to the preheated oven and bake uncovered until the surface turns golden and the filling is bubbling, 25 to 30 minutes.
  • Serve immediately, garnished with fresh chives if preferred.

Notes

For the Panko Topping: In a small mixing bowl, combine Panko, grated Parmesan, lemon zest, and olive oil until the mixture is evenly coated and crumbly.
