Ingredients You’ll Need

1 lb cavatappi pasta
2 cans (10.5 oz each) cream of chicken soup
2 cups half & half
3 tablespoons Dijon mustard
1 tablespoon fresh parsley, chopped
1 teaspoon seasoned salt (e.g., Lawry’s)
½ teaspoon black pepper
3 cups shredded Swiss cheese
2 cups rotisserie chicken, diced
1 tablespoon unsalted butter, melted
¾ cup plain panko bread crumbs
¼ cup grated Parmesan cheese

Yes this is basically comfort food alchemy. Keep that Swiss cheese ready and do not skimp on the panko for the crunch patrol.

Step-by-Step Instructions

4️⃣ Assemble the casserole

Preheat the oven to 350 F and grease a 9 by 13 inch baking dish. Cook the cavatappi following package directions until it is just shy of tender. Drain and set aside so it does not go mushy.
In a large bowl whisk together the cream of chicken soup, half and half, Dijon mustard, parsley, seasoned salt, and black pepper. Taste the mixture and adjust seasoning if you want a little more mustard punch.
Stir in the shredded Swiss cheese and the diced rotisserie chicken. Fold in the cooked pasta until everything looks evenly coated and deliciously saucy.
Transfer the mixture into the prepared baking dish and spread it out in an even layer. This is the time to do a small happy dance because it already smells great.
In a small bowl combine the melted butter, panko bread crumbs, and grated Parmesan. Sprinkle this breadcrumb mixture evenly over the top of the casserole to create a crunchy crown.
Bake on the middle rack for about 25 to 30 minutes until the bubbly edges show and the top is golden brown. If you want extra browning, pop it under the broiler for 1 to 2 minutes but watch it like a hawk.
Let the casserole rest for 5 minutes to set up. Scoop generous portions and serve with a simple green salad or steamed veggies to pretend this is healthy.

Common Mistakes to Avoid

Thinking you do not need to preheat the oven. Rookie mistake. Preheat it.
Overcooking the pasta. Nobody wants a casserole that turns into a sticky noodle swamp. Undercook by a minute or two so it finishes in the oven.
Skimping on the cheese. Do not be that person. Cheese makes things better. End of story.
Forgetting to taste the sauce before baking. You would be amazed at how a little extra mustard or salt can save the whole dish.
Using flavored breadcrumbs by accident. Plain panko gives you the perfect neutral crunch. Flavored crumbs can fight with the mustard and Swiss.

Alternatives & Substitutions

No cavatappi punch? Use penne, rotini, or shells. They all do a fine job at holding sauce. IMO cavatappi is cute but not essential.
Want to swap the rotisserie chicken? Leftover roasted chicken, shredded turkey, or even diced ham would work. Ham makes it feel more like the classic Cordon Bleu.
Half and half too rich or not available? Use whole milk for a lighter version, or a 1 to 1 mix of milk and cream if that is what you have.
Swiss cheese missing in action? Gruyere or provolone can step in, though Swiss is the classic vibe. For a sharper bite, try a mix of Swiss and sharp cheddar.
Gluten free pasta and panko are fine here. Just remember some GF pastas get softer, so keep an eye on texture.

FAQ (Frequently Asked Questions)

Q. Can I use margarine instead of butter?
A. Well technically yes, but why hurt your soul like that? Butter gives the breadcrumbs a nicer flavor and browning.

Q. Can I make this ahead of time and bake later?
A. Absolutely. Assemble the casserole, cover it tightly, and refrigerate for up to 24 hours. Add a few extra minutes to baking time if it goes in cold.

Q. Can I freeze it?
A. Yep. Freeze before baking for up to 2 months. Thaw in the fridge overnight before baking. You may need 10 to 15 extra minutes in the oven.

Q. Is rotisserie chicken necessary?
A. Not necessary, but it sure saves time and adds flavor. Leftover roasted chicken or deli rotisserie style meat works fine.

Q. How can I make it lighter?
A. Swap half and half for whole milk, use less cheese, and use less butter in the breadcrumb topping. Still tasty, just a touch more virtuous.

Q. Can I add veggies?
A. Yes. Peas, mushrooms, or spinach stirred in before baking work great. Keep excess moisture in check by sautéing mushrooms first.

Q. What if I want more crunch?
A. Mix crushed buttery crackers with panko or add a layer of thinly sliced almonds for a fancy crunch.

Final Thoughts

There you go, a casserole that feels like it took effort but actually respects your time and sanity. Pro tip Give the breadcrumb topping a good mix with melted butter so it crisps up perfectly in the oven. Serve this when you want to impress without sweating, or when you simply crave cheesy comfort. FYI this also makes for a stellar potluck offering.

Now go impress someone or yourself with this cozy and slightly fancy casserole. You have earned it.
