Ingredients

Scale

3 cups cooked turkey, shredded or chopped
2 cups frozen mixed vegetables (carrots, peas, corn, green beans), thawed
1 medium onion, finely chopped
2 cloves garlic, minced
3 tablespoons unsalted butter
3 tablespoons all-purpose flour
2 cups chicken broth
1 cup whole milk
1 teaspoon dried thyme
1 teaspoon dried sage
1/2 teaspoon salt
1/4 teaspoon black pepper
1 1/2 cups shredded sharp cheddar cheese
1 cup plain breadcrumbs
2 tablespoons olive oil

Instructions

Preheat the oven to 350°F (175°C).
In a large skillet, melt the butter over medium heat. Add the chopped onion and minced garlic and cook for 3-4 minutes until softened.
Stir in the flour and cook for 1-2 minutes, stirring constantly to form a roux.
Gradually whisk in the chicken broth and milk, continuing to whisk until the sauce thickens, about 5 minutes.
Add the dried thyme, dried sage, salt, and black pepper to the sauce and stir to combine.
Remove the sauce from heat and stir in 1 cup of the shredded cheddar cheese until melted and smooth.
In a large mixing bowl, combine the cooked turkey, thawed mixed vegetables, and cheese sauce. Mix well.
Transfer the mixture to a greased 9×13 inch casserole dish and spread evenly.
In a small bowl, mix the breadcrumbs with olive oil until evenly coated.
Sprinkle the remaining 1/2 cup shredded cheddar cheese over the casserole, then evenly distribute the breadcrumb mixture on top.
Bake in the preheated oven for 35-40 minutes, or until the casserole is bubbly and the topping is golden brown.
Remove from the oven and let it rest for 5 minutes before serving.
