Why This Recipe Works
This recipe works because it relies on a streamlined method to achieve a velvety sauce without needing complex techniques. By using pre-cooked rotisserie chicken or shredded leftovers, you remove the most time-consuming step of the process while maintaining excellent texture.
The combination of parmesan cheese and heavy cream creates a robust flavor profile that clings perfectly to the pasta. Unlike traditional casseroles that can become dry, this version includes enough moisture to remain juicy and succulent after baking. Families love this dish because it provides a balanced meal with protein, starch, and vegetables in one simple baking dish.
Ingredients
| Ingredient | Quantity | Notes |
|---|---|---|
| Cooked Chicken | 3 cups | Rotisserie is preferred |
| Spaghetti | 16 oz | Cooked al dente |
| Mushrooms | 8 oz | Sliced cremini |
| Heavy Cream | 2 cups | For silkiness |
| Parmesan Cheese | 1 cup | Freshly grated |
| Butter | 4 tbsp | Unsalted |
| Chicken Broth | 1 cup | Low sodium preferred |
Step-by-Step Instructions
Preparation
- Preheat your oven to 375 degrees Fahrenheit to ensure an even bake.
- Grease a large 9×13 baking dish with butter to prevent sticking.
Sauce and Assembly
- Melt butter in a large skillet over medium heat and sauté sliced mushrooms until golden.
- Whisk in the flour to create a roux, cooking for one minute to remove the raw flour taste.
- Stir in chicken broth and heavy cream gradually while whisking to avoid clumps.
- Simmer the mixture until it thickens before adding the grated parmesan cheese.
- Combine the cooked spaghetti and shredded chicken into the skillet with the sauce.
Baking
- Transfer the mixture to the prepared baking dish and spread it evenly.
- Top with additional cheese and bake for 20 minutes until the edges bubble.
Chef Tips for Perfect Results
- Always reserve a half cup of the pasta cooking water to adjust the sauce consistency if it appears too thick.
- Use freshly grated parmesan rather than pre-shredded bags to ensure the sauce melts smoothly without graininess.
- Toast the breadcrumbs before adding them as a topping for an extra crunch that contrasts with the creamy pasta.
- Let the finished dish rest for five minutes after removing it from the oven to allow the sauce to set properly.
Common Mistakes to Avoid
One common mistake is overcooking the pasta before it hits the oven; this leads to mushy textures. Always cook the spaghetti to al dente, as it will continue absorbing moisture during the baking process. Another error involves using pre-grated cheese which contains potato starch that prevents proper emulsification. Use a block of cheese and grate it manually for superior melting results.
Variations and Substitutions

Frequently Asked Questions
Can I use rotisserie chicken for this recipe?
Yes, rotisserie chicken provides the best texture and flavor while significantly reducing the prep time. Shred the meat into bite-sized pieces for consistent incorporation.
How do I prevent the sauce from breaking in the oven?
Keep the heat low when incorporating the cream and cheese to maintain a stable emulsion. Avoid boiling the sauce aggressively right before adding it to the pasta.
Is this dish suitable for freezing?
Freeze the baked casserole in individual portions for up to two months, though individual components hold textures better when fresh. Thaw in the refrigerator overnight before reheating in the oven.
What is the secret to perfect doneness?
The bake is complete once the center bubbles and the top cheese layer turns a light golden brown. Overbaking leads to sauce evaporation, while underbaking keeps the center cold.
Can I swap the spaghetti for other pastas?
Short pasta shapes like penne or rotini work well if you prefer easier portion control. Adjust the pasta quantity slightly if using a bulkier shape to maintain the correct sauce ratio.

Ingredients
3 cups cooked shredded chicken

8 oz cremini mushrooms, sliced
2 cups heavy cream
1 cup freshly grated parmesan cheese
4 tbsp unsalted butter
1 cup low sodium chicken broth
3 tbsp all-purpose flour
Black pepper to taste
Salt to taste
Instructions
Preheat your oven to 375 degrees Fahrenheit and grease a 9×13 baking dish with butter.
Melt the butter in a large skillet over medium heat and sauté the mushrooms until golden brown.
Stir in the flour and cook for one minute to form a light roux.
Gradually whisk in the chicken broth and heavy cream, cooking until the sauce thickens.
Add the grated parmesan cheese to the sauce and stir until melted and smooth.
Fold the cooked spaghetti and shredded chicken into the skillet with the sauce until well combined.
Transfer the mixture into the prepared baking dish and smooth the top.
Bake for 20 minutes until the top is bubbling and lightly golden.
Notes
Ensure you cook the spaghetti just shy of al dente, as it will continue to soften in the oven. For extra flavor, sprinkle a little more parmesan cheese over the top before baking. Store leftovers in an airtight container for up to 3 days.
