Chef John’s Turkey Noodle Casserole transforms Thanksgiving leftovers into a creamy, cheesy comfort dish with egg noodles, tender turkey, and a crunchy panko topping, ready in under an hour for 6-8 servings. This elevated classic skips canned soups for a from-scratch cream sauce enriched with Gruyère and nutmeg, balancing richness with bright veggies like peas and celery. Ideal for post-holiday meals, it reheats beautifully.
Ingredients
For the Casserole:
- 2 tbsp unsalted butter
- 1/2 cup diced onion
- 1/2 cup diced celery
- 2 cloves garlic, minced
- 3 tbsp all-purpose flour
- 2 1/2 cups whole milk
- 1 pinch freshly grated nutmeg
- Salt and black pepper to taste
- 1 pinch cayenne pepper
- 3 cups cubed cooked turkey (about 1 lb)
- 2 cups frozen peas, thawed
- 3 cups uncooked egg noodles (wide)
- 1 cup grated Gruyère cheese (4 oz)
- 1/2 cup grated sharp white cheddar (2 oz)
For the Topping:
- 2 tbsp unsalted butter, melted
- 1/2 cup panko breadcrumbs
- 1/2 cup grated Parmigiano-Reggiano
- 1 tsp chopped fresh thyme or parsley
Instructions
Preheat oven to 350°F (175°C); grease a 9×13-inch baking dish. Cook noodles in boiling salted water 1-2 minutes less than package (al dente); drain and set aside. Melt 2 tbsp butter in skillet over medium; sauté onion, celery, garlic 5 minutes until soft. Stir in flour; cook 1 minute. Gradually whisk in milk; simmer until thickened (3-5 minutes). Season with nutmeg, salt, pepper, cayenne.
Off heat, stir in turkey, peas, cheeses until melted. Fold in noodles; transfer to dish. Mix melted butter, panko, Parm, thyme; sprinkle evenly. Bake 25-30 minutes until golden and bubbly. Broil 1-2 minutes for crisp top if needed. Rest 10 minutes before serving.
Tips for Perfection
Use rotisserie or leftover turkey; shred for even distribution. Freshly grated nutmeg elevates sauce—don’t skip. Undercook noodles to avoid mushiness post-bake. Make-ahead: assemble, cover, refrigerate up to 24 hours; add 10 minutes bake time. Freeze unbaked up to 2 months; thaw overnight.
