Ingredients

Scale
  • 1.5 pounds leftover turkey, chopped or shredded
  • Cooked rice, for serving
  • 1 pound broccoli, cut into florets or bite-sized pieces
  • ½ teaspoon kosher salt
  • ¼ teaspoon black pepper
  • ½ cup water
  • Cheese Sauce:
  • 2 tablespoons olive oil
  • 2 tablespoons unsalted butter
  • ⅓ cup all-purpose flour
  • 1.5 cups turkey broth (or chicken broth)
  • 2 cups whole milk
  • 1 teaspoon Dijon mustard
  • 1 teaspoon chicken bouillon
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon dried parsley
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ cup sour cream
  • 1.5 cups shredded cheddar cheese, divided
  • ½ cup shredded Parmesan cheese
  • Panko Topping:
  • 2 tablespoons butter
  • 1 cup panko crumbs

Instructions

1. Preheat the oven to 350°F and spray a 9×13 baking dish with cooking spray. Set aside.

2. In a large pan over medium heat, bring ½ cup of water to a light simmer. Add broccoli, salt, and pepper. Cover and steam for a few minutes until bright green and slightly crisp. Drain and place in the baking dish.

3. Layer the chopped or shredded turkey evenly over the broccoli.

4. In the now empty pan, heat olive oil and butter over medium heat. Add flour and whisk until clumpy and cooked through.

5. Slowly whisk in broth and milk. Add Dijon mustard, sour cream, and seasonings. Bring to a light simmer and cook for 5–10 minutes, whisking often, until thickened.

6. Remove from heat and stir in ½ cup cheddar cheese and all the Parmesan until melted. Pour over the turkey and broccoli, spreading evenly. Sprinkle the remaining cheddar on top.

7. In a small pan, melt butter over medium heat. Add panko crumbs and toss to coat. Toast until golden, then spread evenly over the casserole. Cover with foil.

8. Bake for 30 minutes. Remove foil and bake an additional 5–10 minutes, until bubbly and golden. Broil briefly for extra crispiness, if desired.

9. Remove from oven and cool for 10 minutes before serving. Serve over rice.

Notes

Use a mix of turkey breast and dark meat, but remove the skin as it can become chewy.

Only use freshly shredded cheese for the best melt and texture.

Panko, Italian breadcrumbs, or crushed Ritz crackers all make great topping options.

Stick to fresh broccoli – frozen broccoli tends to get too mushy.

Serve over your favorite cooked rice for a complete meal.
