- 4 tbsp unsalted butter, divided
- 1 medium yellow onion, diced
- 1 cup carrots, diced
- 1/2 cup celery, diced
- 2 cloves garlic, minced
Creamy Sauce
- 1/3 cup all-purpose flour
- 2 1/2 cups low-sodium chicken broth
- 1 cup whole milk
- 1/2 cup heavy cream (optional, for extra richness)
- 3/4 cup frozen peas (do not thaw)
- 1/2 cup shredded sharp cheddar cheese (optional)
- 1 tsp dried thyme (or 1 tbsp fresh)

- 1 tsp kosher salt (adjust to taste)

Pastry Topping
- 1 sheet puff pastry, thawed

Instructions
- Preheat the Oven
Heat your oven to 400°F (200°C). Lightly grease a 9-inch pie dish or 8×8-inch baking dish. - Cook the Pasta
Bring salted water to a boil. Cook pasta until al dente (8–10 minutes). Drain and set aside. - Sauté the Vegetables
In a large skillet or Dutch oven, heat the olive oil and 2 tbsp butter over medium heat.
Add onion, carrots, and celery. Cook 6–8 minutes until softened. Add garlic and cook 30–45 seconds. - Make the Roux
Push vegetables to one side. Add remaining 2 tbsp butter, then sprinkle in the flour.
Stir 1–2 minutes to cook the flour. - Build the Sauce
Slowly whisk in chicken broth, scraping up any browned bits.
Add milk and heavy cream. Simmer 3–5 minutes until thickened. - Add Chicken & Seasoning
Stir in shredded chicken, peas, thyme, salt, pepper, and cheddar (if using).
Taste and adjust seasoning. - Combine with Pasta
Fold in the cooked pasta and parsley.
If too thick, add a splash of broth or milk; if too thin, simmer 1–2 minutes. - Assemble the Dish
Transfer the pasta mixture to your baking dish and smooth the top. - Add the Puff Pastry
Place puff pastry over the top, trimming as needed. Press edges to seal.
Cut 2–3 small slits to vent steam. - Brush & Bake
Brush with egg wash.
Bake 18–22 minutes, until pastry is golden and filling is bubbling.
Tent with foil if browning too quickly. - Cool & Serve
Let rest 5–10 minutes before serving. Garnish with extra parsley if desired.
