Creamy Turkey Vegetable Casserole with Crispy Herb Crumb Topping
This creamy turkey casserole is the kind of cozy comfort food that disappears fast at the dinner table. Tender shredded turkey is baked in a rich creamy sauce with peas, carrots, celery, and herbs, then topped with buttery golden breadcrumbs for the perfect crispy finish. It’s a great way to use leftover turkey and honestly tastes even better the next day.
In a large skillet or Dutch oven, heat olive oil and 2 tbsp butter over medium heat.
Add onion, celery, and carrots. Cook for about 6–8 minutes until softened.
Stir in garlic, thyme, rosemary, salt, and pepper. Cook another minute until fragrant.
Add peas and shredded turkey. Set aside.
Step 2: Make the Cream Sauce
In a separate saucepan, melt 4 tbsp butter over medium heat.
Whisk in flour and cook for 1–2 minutes to remove the raw flour taste.
Slowly whisk in broth, then milk and cream until smooth.
Cook until thickened and creamy, about 4–5 minutes.
Stir in Parmesan cheese, Dijon mustard, and garlic powder.
Taste and adjust seasoning if needed.
Step 3: Assemble the Casserole
Pour the cream sauce over the turkey mixture and stir until evenly coated.
Transfer everything into a large greased casserole dish.
Step 4: Make the Crispy Topping
In a bowl combine: panko breadcrumbs, melted butter, Parmesan, parsley, and pinch of salt and pepper
Sprinkle evenly over the casserole.
Step 5: Bake
Bake uncovered for 25–30 minutes until bubbling around the edges and deeply golden on top.
For extra browning, broil for 1–2 minutes at the end.
Let rest 5–10 minutes before serving.
Rotisserie chicken works perfectly if you don’t have leftover turkey.Fresh rosemary really boosts the cozy holiday flavor.Don’t overbake or the sauce can tighten too much.A little Parmesan in the filling adds depth without making it overly cheesy.Panko breadcrumbs stay crispier than regular breadcrumbs.
