Ingredients
Scale
- 2 tablespoons olive oil
- 3/4 cup panko breadcrumbs
- 1 1/4 teaspoons kosher salt, divided
- 12 ounces dried wide egg noodles (about 9 cups)
- 1 medium yellow onion, diced
- 2 medium carrots, peeled and diced
- 1 medium stalk celery, diced
- 3 cloves garlic, minced
- 1 small bunch fresh parsley (1/2 cup chopped leaves)
- 2 (5- to 6-ounce) cans tuna, preferably oil-packed, drained and flaked
- 1 ounce Parmesan cheese (1/2 cup freshly grated or 1/3 cup store-bought grated)
- 4 tablespoons (1/2 stick) unsalted butter
- 1/2 teaspoon freshly ground black pepper
- 1/4 cup all-purpose flour
- 2 cups low-sodium chicken broth
- 2 cups whole or 2% milk
- 1 tablespoon Dijon mustard
- 1 cup frozen peas (do not thaw)
Instructions
- Preheat oven to 375℉ and position a rack in the center.
- Heat olive oil in a Dutch oven over medium heat. Add panko and 1/4 teaspoon salt. Stir until golden brown, 3–4 minutes. Transfer to a bowl and let cool.
- Wipe out the Dutch oven, fill with salted water, and bring to a boil. Add noodles and cook 3 minutes less than package directs. Drain and rinse the pot.
- Dice onion, carrots, and celery. Mince garlic. Chop parsley. Drain and flake tuna. Grate Parmesan and add to panko; mix.
- Melt butter in Dutch oven over medium heat. Add onion, carrots, celery, remaining salt, and pepper. Cook until onion is translucent, about 5 minutes.
- Add garlic; cook 30 seconds. Add flour and stir to coat vegetables; cook 1 minute.
- Pour in chicken broth, milk, and Dijon mustard. Stir and scrape the bottom. Simmer until thickened, 5–7 minutes.
- Remove from heat. Stir in parsley, tuna, and frozen peas. Mix in the noodles.
- Transfer mixture to a 9×13-inch baking dish. Spread evenly and top with the panko-Parmesan mixture.
- Bake 20–25 minutes, or until bubbling and golden brown on top.
Notes
- Use oil-packed tuna for richer flavor.
- Don’t thaw the peas beforehand—they’ll cook perfectly in the oven.
- Substitute whole milk with 2% if desired.
- Make ahead: Assemble and refrigerate for up to 1 day before baking.
- Use fresh parsley for best flavor, but dried works in a pinch.
