Cook Time: 20 minutes
Servings: 6
Ingredients:
- 8 oz wide egg noodles
- 3 tbsp unsalted butter
- 1 cup diced white onion
- 2 stalks celery, finely chopped
- 3 tbsp all-purpose flour
- 1 ½ cups low-sodium vegetable broth
- 1 ½ cups whole milk
- 1 tsp sea salt
- ¼ tsp freshly ground black pepper
- ½ tsp dried oregano
- 1 ½ cups mixed frozen peas and diced carrots
- 2 cans (5 oz each) chunk light tuna in water, well-drained
- 1 cup sharp cheddar cheese, shredded (about 4 oz)
Topping:
- ¾ cup panko breadcrumbs
- 2 tbsp grated Parmesan cheese
- 1 tbsp unsalted butter, melted
- Optional: Fresh parsley leaves, chopped for garnish
Instructions:
- Preheat your oven to 375°F (190°C).
- In a large pot, bring water to a boil. Cook egg noodles until al dente, then drain and rinse under cold water. Set aside.
- In a large skillet over medium heat, melt 3 tbsp of butter. Add diced onion and celery, cooking until softened (about 4-5 minutes).
- Add flour to the skillet, stirring for 30 seconds. Gradually add vegetable broth and milk, stirring constantly. Include salt, pepper, and dried thyme. Continue cooking until the sauce thickens (approximately 2-3 minutes).
- Remove the skillet from heat, and stir in frozen peas and carrots, drained tuna, shredded cheddar cheese, and cooked egg noodles. Transfer this mixture to a 13×9-inch baking dish.
- For the topping, combine panko breadcrumbs, grated Parmesan cheese, and 1 tbsp melted butter in a medium bowl. Sprinkle this mixture evenly over the casserole.
- Place the baking dish in the preheated oven, uncovered, and bake for 15-20 minutes or until the casserole is heated throughout, and the topping achieves a beautiful golden-brown color.
- Serve hot, optionally garnished with chopped fresh parsley.
