This hearty casserole brings together the best of chicken pot pie and pasta. Shredded chicken, peas, carrots, corn, and celery swim in a velvety homemade white sauce seasoned with thyme and parsley. The mixture coats penne or rotini perfectly, then gets crowned with a buttery Parmesan-panko topping that bakes golden and crisp. Ready in about 50 minutes, this serves four generously and easily adapts to leftover turkey or extra vegetables.
The smell of butter hitting a hot skillet still takes me back to my first apartment, where I'd cook whatever comfort food reminded me of home. This chicken pot pie pasta came together on a particularly gloomy Tuesday when I couldn't decide between making a proper pot pie or just boiling pasta for dinner.
My roommate walked in midway through sauce-making and literally hovered over the stove with a spoon. We ended up eating it straight from the baking dish while watching a movie, both agreeing it was better than either dish on its own.
Ingredients
- 2 cups cooked chicken breast: Leftover rotisserie chicken works perfectly here and actually has more flavor than plain boiled breast
- 12 oz short pasta: Penne or rotini catch all that sauce in their crevices, plus they hold up well under the broiler
- 1 cup frozen peas and carrots blend: The frozen vegetables actually work better than fresh here because they release just the right amount of water into the sauce
- 1/2 cup frozen corn: Adds these little bursts of sweetness that balance the savory creaminess
- 1/2 cup diced celery and onion: These aromatics build the flavor foundation, so don't rush this step
- 2 cloves garlic: Minced fresh because garlic powder just doesn't have the same punch in a cream sauce
- 3 tbsp butter and 3 tbsp flour: This is your roux, the magic thickening base that makes everything silky
- 2 cups chicken broth and 1 cup whole milk: The broth gives depth while the milk adds richness
- 1/2 tsp dried thyme and parsley: Classic pot pie herbs that make it taste like home
- 1/2 tsp black pepper and 3/4 tsp salt: Adjust these after tasting, as some broths are saltier than others
- 1/2 cup grated Parmesan and 1/2 cup panko: This topping creates the crust that everyone fights over
- 2 tbsp melted butter: Mixed into the topping to ensure it gets properly golden and crispy
Instructions
- Get your oven and pasta going:
- Preheat oven to 375°F and grease a 9x13 baking dish while you boil salted water for the pasta, cooking it just until al dente
- Build your flavor base:
- Melt 3 tbsp butter in a large skillet over medium heat, then cook onion, celery, and garlic for 3 to 4 minutes until softened and fragrant
- Create the creamy sauce:
- Sprinkle in flour and stir constantly for 1 minute before gradually whisking in broth and milk, letting it simmer until thickened
- Add the seasonings and fillings:
- Stir in thyme, parsley, salt, and pepper, then add chicken, peas, carrots, and corn, cooking until everything is heated through
- Combine and top:
- Mix in the cooked pasta, pour everything into your baking dish, then toss panko, Parmesan, and melted butter together before sprinkling it evenly over the top
- Bake until golden:
- Bake for 20 to 25 minutes until the sauce is bubbling up around the edges and that topping has turned golden brown
- Let it rest:
- Wait 5 minutes before serving so the sauce has time to set slightly, making it easier to scoop
This has become my go-to when friends need comforting, and I've learned to always make extra because the leftovers somehow taste even better the next day.
Make It Your Own
The beauty of this dish is how forgiving it is. I've swapped in leftover turkey after Thanksgiving and added mushrooms when I needed to use them up.
The Secret To The Perfect Crust
Mixing the melted butter into the panko and Parmesan before sprinkling it on top is what makes it actually crisp up instead of just staying dry and sandy.
Serving Suggestions
A simple green salad with vinaigrette cuts through the richness, and a crisp white wine like Sauvignon Blanc pairs beautifully. Keep the sides light since this is such a hearty main.
- Arugula with lemon dressing adds a nice peppery contrast
- Garlic bread is never a bad idea if you want to go all out
- Steamed broccoli brings some crunch and color to the plate
There's something about pulling this bubbling dish out of the oven that makes even a regular Tuesday feel like a small celebration.
Recipe Questions & Answers
- → Can I make this ahead of time?
-
Yes, assemble the casserole up to 24 hours in advance, cover tightly, and refrigerate. Add an extra 10-15 minutes to the baking time since it will be cold.
- → What pasta shapes work best?
-
Short pasta with ridges or tubes like penne, rotini, or gemelli capture the creamy sauce beautifully. Avoid long strands like spaghetti—the sauce won't cling properly.
- → Can I freeze leftovers?
-
Absolutely. Portion cooled leftovers into airtight containers and freeze up to 3 months. Thaw overnight in the refrigerator and reheat at 350°F until bubbly throughout.
- → How do I get the topping extra crispy?
-
Broil for the final 2-3 minutes, watching closely to prevent burning. The butter in the breadcrumb mixture helps achieve that golden crunch.
- → What substitutions can I make?
-
Swap leftover turkey for chicken, add mushrooms or green beans, or use gluten-free pasta and flour blend. Greek yogurt can replace half the milk for extra protein.
- → Why is my sauce too thick or thin?
-
Sauce consistency depends on how long it simmers. If too thick, add more broth a tablespoon at a time. Too thin? Cook another minute or two—flour continues thickening off heat.
