How to Make Creamy Cheesy Chicken Tortellini Bake
1. Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish.
2. Bring the Pasta Water to a Boil
Fill a large pot with water.
Season lightly with salt and bring to a boil.
3. Cook the Tortellini
Add the refrigerated tortellini.
Cook approximately 1–2 minutes less than the package directions.
The tortellini should still be slightly firm because it will continue cooking in the oven.
4. Reserve Pasta Water
Before draining, reserve approximately ½ cup pasta water.
5. Drain Carefully
Drain the tortellini gently.
Do not rinse.
Set aside.
6. Prepare the Chicken
Place the cooked chicken in a bowl.
Add:
- Garlic powder
- Onion powder
- Italian seasoning
- Smoked paprika
- Black pepper
Toss gently.
If you are cooking chicken specifically for this recipe, cook it to 165°F (74°C) before adding it to the casserole.
7. Melt the Butter
Place a large deep skillet or saucepan over medium heat.
Add the butter.
8. Add the Garlic
Stir in the minced garlic.
Cook for approximately 30–60 seconds, just until fragrant.
Do not allow it to burn.
9. Add the Flour
Sprinkle in the flour.
Whisk continuously for approximately 1–2 minutes.
This creates the base for the creamy sauce.
10. Add the Chicken Broth
Slowly pour in the chicken broth while whisking.
Continue until smooth.
11. Add the Milk
Gradually pour in the milk.
Whisk continuously to prevent lumps.
12. Add the Heavy Cream
Stir in the heavy cream.
13. Add the Seasonings
Add:
- Dijon mustard
- Italian seasoning
- Garlic powder
- Onion powder
- Black pepper
- Red pepper flakes, if using
14. Simmer the Sauce
Cook over medium-low heat for approximately 4–6 minutes, stirring frequently.
The sauce should begin to thicken.
15. Lower the Heat
Reduce the heat to low.
Avoid aggressively boiling the sauce once the cheese is added.
16. Add Parmesan
Gradually add the Parmesan.
Stir continuously until melted and smooth.
17. Check the Consistency
The sauce should be creamy but still slightly loose.
It will thicken further during baking.
If it becomes too thick, stir in reserved pasta water a few tablespoons at a time.
18. Taste and Adjust
Taste before adding salt because Parmesan already contributes plenty of saltiness.
Adjust pepper, garlic, or Dijon as desired.
19. Add Optional Spinach
If using spinach, stir it directly into the hot sauce.
Cook for approximately 1 minute, just until wilted.
20. Add the Chicken
Stir the seasoned chicken into the sauce.
21. Add the Tortellini
Add the cooked tortellini.
Fold everything together gently so the pasta does not break.
22. Add Other Optional Ingredients
If using broccoli, mushrooms, sun-dried tomatoes, or bacon, fold them in now.
23. Transfer to the Baking Dish
Spoon the tortellini mixture into the prepared baking dish.
Spread into an even layer.
24. Add Mozzarella
Sprinkle the mozzarella evenly over the top.
25. Add Provolone or Monterey Jack
If using, sprinkle it over the mozzarella.
26. Add Parmesan
Finish with freshly grated Parmesan.
27. Cover
Cover loosely with foil.
28. Bake Covered
Bake for approximately 15 minutes.
29. Remove the Foil
Carefully uncover the baking dish.
30. Continue Baking
Bake for another 10–15 minutes.
The sauce should be bubbling around the edges and the cheese fully melted.
31. Broil for Extra Browning
For a golden cheese topping, broil for approximately 1–2 minutes.
Watch carefully.
32. Rest
Remove the casserole from the oven.
Let it rest for approximately 5–10 minutes.
This gives the sauce time to thicken slightly.
33. Garnish
Finish with:
- Fresh parsley
- Fresh basil
- Extra Parmesan
- Black pepper
- Red pepper flakes
34. Serve
Spoon generous portions onto plates and serve hot.
