This comforting casserole combines the best of chicken pot pie with pasta. Shredded chicken, frozen vegetables, and tender penne are coated in a creamy homemade sauce made with butter, flour, chicken broth, and milk. Seasoned with thyme, parsley, salt, and pepper, the mixture gets a crispy topping of panko breadcrumbs and Parmesan cheese before baking until golden and bubbly.
Ready in under an hour, this dish transforms simple ingredients into a satisfying family meal. The creamy sauce binds everything together while the breadcrumb topping adds delightful crunch. Perfect for using leftover chicken or turkey, and easily customizable with your favorite vegetables.
The first time I made this hybrid dish, my husband looked at me like I had lost my mind when he saw me boiling pasta for what was supposed to be pot pie night. But one bite of that crispy, golden topping over creamy noodles and he was completely converted. Now it's the most requested comfort food in our house, especially on those bone-chilling February nights when we need something that hugs back.
Last winter, my sister came over for dinner after a terrible week at work. I watched her shoulders drop two inches when she took that first bubbling spoonful, and she actually closed her eyes mid-bite. She asked for the recipe before she even finished her plate, and now she makes it for her family every Sunday night.
Ingredients
- 2 cups cooked chicken breast, shredded: Rotisserie chicken works beautifully here, and I always save the extra breast meat when I make stock for this exact purpose
- 12 oz (340 g) short pasta: Penne catches the sauce in those ridges, but rotini works just as well—whatever you have waiting in the pantry
- 1 cup frozen peas and carrots blend: The frozen vegetables actually work better than fresh here because they hold their texture through the baking
- 1/2 cup frozen corn: Adds little bursts of sweetness that balance the savory cream sauce perfectly
- 1/2 cup diced celery and 1/2 cup diced onion: These create the classic pot pie aromatic foundation, so do not skip the sauté step
- 2 cloves garlic, minced: Fresh garlic makes such a difference here, jarred garlic cannot compete with that mellow roasted flavor
- 3 tbsp unsalted butter: Use real butter for the roux, margarine will give your sauce an odd waxy texture
- 3 tbsp all-purpose flour: This creates the silky thickness that transforms milk and broth into that luxurious pot pie sauce
- 2 cups chicken broth and 1 cup whole milk: The combination gives you depth of flavor while keeping the sauce rich and creamy without being heavy
- 1/2 tsp dried thyme and 1/2 tsp dried parsley: These herbs scream comfort food and taste exactly like what grandma used to make
- 3/4 tsp salt and 1/2 tsp black pepper: Season the sauce generously since the pasta will absorb some of the salt as it bakes
- 1/2 cup grated Parmesan cheese: The salty nuttiness of real Parmigiano-Reggiano makes that topping absolutely irresistible
- 1/2 cup panko breadcrumbs: Panko stays lighter and crunchier than traditional breadcrumbs, creating that perfect golden crust
- 2 tbsp unsalted butter, melted: Tossing the panko in melted butter helps it turn that gorgeous golden brown in the oven
Instructions
- Get your oven ready:
- Preheat oven to 375°F (190°C) and grease a 9x13-inch baking dish with butter or cooking spray
- Cook the pasta:
- Boil pasta in salted water until al dente, then drain—it will cook more in the oven so do not overdo it now
- Sauté the aromatics:
- Melt 3 tbsp butter in a large skillet over medium heat, then cook onion, celery, and garlic for 3–4 minutes until they soften and your kitchen starts smelling amazing
- Build the sauce base:
- Sprinkle flour over the vegetables and stir constantly for 1 minute to cook out that raw flour taste
- Create the creamy sauce:
- Whisk in chicken broth and milk gradually, then simmer for 3–4 minutes until the sauce coats the back of a spoon
- Season and add filling:
- Stir in thyme, parsley, salt, and pepper, then add chicken, peas, carrots, and corn and heat everything through for 2 minutes
- Combine with pasta:
- Pour the sauce over your cooked pasta and mix until every noodle is coated in that velvety goodness
- Transfer to baking dish:
- Pour the entire mixture into your prepared baking dish and spread it evenly
- Make the golden topping:
- Mix panko, Parmesan, and melted butter in a small bowl until combined, then sprinkle it all over the casserole
- Bake until bubbly:
- Bake for 20–25 minutes until you see the sauce bubbling up around the edges and the topping is golden brown
- Let it rest:
- Wait 5 minutes before serving—this helps the sauce set slightly so it does not run all over the plate
My youngest daughter, who usually picks out every visible vegetable, somehow never notices the peas and carrots in this dish. Something about that creamy sauce and crunchy topping makes everything taste better together.
Make It Your Own
Leftover turkey from Thanksgiving works just as well as chicken, and I have even used rotisserie chicken from the grocery store on busy weeknights. Sometimes I add mushrooms or green beans when I want to sneak in more vegetables.
Perfect Pairings
A crisp green salad with vinaigrette cuts through the richness beautifully. I usually serve it with a chilled Sauvignon Blanc or even just some cold water with lemon.
Make Ahead Magic
You can assemble the entire casserole up to 24 hours ahead and keep it covered in the refrigerator. Add an extra 5–10 minutes to the baking time if it is cold from the fridge.
- Freeze unbaked casseroles for up to 3 months, wrapped tightly in foil and plastic
- Thaw overnight in the refrigerator before baking as directed
- The topping stays crunchier when added just before baking rather than freezing with it
There is something so satisfying about hearing that crispy topping crackle when you scoop out that first serving. This is the kind of food that makes a house feel like home.
Recipe Q&A
- → Can I make this ahead of time?
-
Yes, assemble the casserole up to 24 hours in advance and refrigerate. Add an extra 10-15 minutes to the baking time if baking from cold.
- → What pasta shapes work best?
-
Short pasta shapes like penne, rotini, or fusilli catch the creamy sauce well. Avoid long strands like spaghetti as they don't hold the thick sauce properly.
- → Can I freeze leftovers?
-
Absolutely. Portion leftovers into airtight containers and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
- → How do I know when the sauce is thick enough?
-
The sauce is ready when it coats the back of a spoon and leaves a clear trail when you run your finger through it. This typically takes 3-4 minutes of simmering.
- → Can I use fresh vegetables instead of frozen?
-
Yes, but add them earlier in the process. Sauté carrots and celery with the onions, and add fresh peas or corn when you add the chicken to ensure they cook through.
- → What's the best way to reheat?
-
Cover with foil and reheat at 350°F until warmed through, about 20-25 minutes. For individual portions, microwave with a splash of milk to restore creaminess.
