Chicken Stuffing Stuffed Shells (Bake Recipe)
Make 20 hearty stuffed shells by filling jumbo pasta shells with cooked chicken, prepared stuffing, ricotta, and mozzarella. Arrange them over marinara in an oven-safe 9 × 13-inch dish, cover with sauce and cheese, then bake at 375°F (190°C) until the center reaches 165°F (74°C). Rest 5–10 minutes before serving.
What if you want a cozy baked pasta dinner but don’t want to cook a separate side dish or fuss with a complicated filling? These chicken and stuffing shells bring familiar casserole flavors into a dish that’s easy to portion and serve. The key is to cook the shells just shy of tender, keep the filling moist, and check the casserole’s temperature before it comes out of the oven.
Material Setup & Ingredient Prep
This recipe makes 20 stuffed shells in a 9 × 13-inch baking dish. Gather the pasta, cooked chicken, prepared stuffing, cheeses, and marinara before you start. Check that your dish is rated for a 375°F oven, and use a food thermometer to confirm that the center of the finished casserole reaches 165°F.
Ingredients and equipment
- 20 jumbo pasta shells
- 2 cups chopped cooked chicken
- 1½ cups prepared stuffing
- 1 cup ricotta
- 1½ cups shredded mozzarella, divided
- 3 cups marinara sauce, divided
- A little chicken broth, only if the filling seems dry
- A 9 × 13-inch oven-rated baking dish
- Foil and a food thermometer
“Prepared stuffing” means stuffing that has already been mixed and cooked according to its package directions, or a cooked leftover version. Let it cool enough to handle before mixing it with the chicken and cheeses. The chicken must also be cooked before it goes into the filling.
Choose the dish and prep the pasta
A glass, ceramic, enameled, or stainless-steel baking dish can work if its maker marks it as safe for a 375°F oven. Check the dish’s stated limit, especially with glass or ceramic. Avoid sudden temperature changes: a cold, wet surface or cold liquid against a hot glass or ceramic dish can cause it to crack.
Tomatoes are acidic, so use marinara in a nonreactive stainless-steel or enamel vessel if you heat sauce on the stovetop. You can skip stovetop heating and use the sauce straight from its container. Induction compatibility matters only if you use stovetop cookware; its base must be magnetic.
Boil the shells for about 2 minutes less than the package directs. This slightly firm stage helps them hold their shape as you fill them and finish baking. Drain them gently so they do not split, then let them cool until you can handle them. Meanwhile, heat the oven to 375°F (190°C).
Stuffing, Filling & Baking Technique
This section covers the full assembly and bake. Mix the cooked chicken, prepared stuffing, ricotta, and part of the mozzarella, then fill the shells without packing them hard. Sauce below and above the pasta helps keep it moist; foil traps heat early, while an uncovered finish melts and browns the cheese lightly.
Mix and fill the shells
Stir together 2 cups chopped cooked chicken, 1½ cups prepared stuffing, 1 cup ricotta, and ½ cup shredded mozzarella. The mixture should hold together but still feel moist. If it looks crumbly or dry, add a small splash of chicken broth, mix, and check again. Add broth gradually so the filling does not become loose.
Spread 1½ cups marinara sauce across the bottom of the baking dish. Spoon the filling into each shell, dividing it as evenly as you can. Arrange the shells in one layer over the sauce. They can sit close together, but avoid pressing them down so firmly that the filling squeezes out.
| Step | Amount or setting | What to check |
|---|---|---|
| Pasta | 20 jumbo shells | Cook about 2 minutes less than package directions |
| Filling | 2 cups chicken, 1½ cups stuffing, 1 cup ricotta, ½ cup mozzarella | Add a little broth if dry |
| Sauce under shells | 1½ cups | Cover the dish bottom |
| Sauce and cheese on top | 1½ cups sauce, 1 cup mozzarella | Cover the shells evenly |
| Oven | 375°F (190°C) | Confirm the dish is oven-rated |
| Bake | 20 minutes covered, then 10–15 minutes uncovered | Center must reach 165°F (74°C) |
Bake and check the center
Spoon the remaining 1½ cups marinara over the shells, then scatter the remaining 1 cup mozzarella on top. Cover the dish loosely with foil and bake for 20 minutes. Remove the foil and bake for another 10–15 minutes, until the sauce is bubbling and the cheese has melted.
Baking time is a guide, not a safety check. Insert a food thermometer into the center of the casserole, taking care not to measure only the hot sauce or touch the dish. The center needs to reach 165°F (74°C). If it has not, continue baking and check again.
If you use a greased dish, apply a small amount of suitable liquid oil only where needed. Refined canola oil often has a smoke point around 400–450°F (204–232°C), but this varies by product. Smoke point is not a safe-use temperature for nonstick coatings. PTFE cookware limits also vary by maker, so do not put it in the oven unless it is explicitly rated for that use. For this bake, the simplest choice is an oven-rated baking dish.
Cleaning & Cookware Care
Good cleanup starts with serving and storing the casserole safely. Move leftovers into shallow containers and refrigerate them within 2 hours. Let the baking dish cool before washing, and use warm soapy water with a nonabrasive sponge to help protect its surface.
After dinner, transfer leftover shells and sauce into shallow containers rather than leaving them in the baking dish to cool for a long time. Refrigerate within 2 hours. If the dish is glass or ceramic, let it cool before washing; do not rinse a hot dish with cold water or set it on a cold, wet surface.
Wash the cooled dish with warm, soapy water and a nonabrasive sponge. Avoid tools or cleaners that could scratch the finish. Follow the dish maker’s care instructions, since coatings and materials can have different limits.
| Situation | Practical choice | Why it helps |
|---|---|---|
| You have an oven-rated glass or ceramic dish | Use it only within its marked oven limit | Helps avoid damage from excess heat or sudden temperature changes |
| You are heating tomato sauce on the stovetop | Choose nonreactive stainless steel or enamel | Suitable for acidic tomato sauce |
| You want to use nonstick cookware in the oven | Check the maker’s oven rating first | PTFE limits vary by product |
| You need to wash a hot glass or ceramic dish | Let it cool before washing | Avoids sudden temperature changes that may cause cracking |
Resting & Serving Presentation
Resting lets the filling settle so the shells are easier to lift and serve. Once the casserole has reached 165°F (74°C), take it out of the oven and leave it undisturbed for 5–10 minutes. Serve the shells with extra marinara if you like, and refrigerate leftovers promptly.
The sauce may look loose straight from the oven, and the shells may shift as you scoop them. A short rest helps the filling settle and makes portions easier to lift. Use a broad spoon or spatula to support each shell as you serve it.
You can bring extra marinara to the table for anyone who wants more sauce. If you plan to serve the casserole straight from a glass or ceramic dish, place it on a dry, heat-safe surface rather than a cold or wet one. Refrigerate leftovers within 2 hours.
Useful adjustments for different kitchens
| If you’re working with… | Try this |
|---|---|
| Leftover cooked chicken | Chop it into small pieces so it mixes evenly |
| Stuffing that feels dry | Add chicken broth a little at a time |
| Shells that tear while filling | Handle them gently and leave split shells out of the dish |
| A deeper or smaller baking dish | Keep shells in one layer when possible; check the center temperature rather than relying only on the timer |
| A make-ahead casserole | Keep it chilled until baking and use the thermometer to confirm the center reaches 165°F (74°C) |
Conclusion and FAQ
This baked pasta uses familiar ingredients and a clear sequence: slightly undercook the shells, mix a moist filling, layer with marinara, and bake until the center reaches 165°F. Resting before serving makes portions easier to handle. Keep the dish within its oven rating, and cool leftovers safely.
Can I use rotisserie chicken?
Yes. Remove the meat from the bones, chop it, and measure 2 cups for the filling. It should be cooked before you mix it in.
Should I cook the shells all the way first?
No. Boil them about 2 minutes less than the package directions so they stay firm enough to fill and finish baking.
What does “prepared stuffing” mean?
It means stuffing that has already been mixed and cooked according to its package directions, or cooked leftover stuffing.
Can I make the filling ahead?
You can mix the filling ahead and keep it refrigerated. Fill and bake the shells when ready, then check the casserole center with a thermometer for 165°F (74°C).
Can I assemble the shells ahead of time?
Yes, if you keep the assembled dish refrigerated until baking. Bake until the center reaches 165°F (74°C), since a chilled dish may need more time than the recipe’s estimate.
How do I keep the filling from being dry?
Mix in a small splash of chicken broth if the filling looks crumbly or dry. Add it gradually; too much can make the filling loose.
Can I use a different baking dish?
Yes, if it fits the shells in one layer and is rated for a 375°F (190°C) oven. Check the maker’s limit, especially for glass or ceramic.
How do I know the shells are done?
The sauce should be bubbling, but use a food thermometer to check the casserole center. It must reach 165°F (74°C).
How long should the casserole rest?
Rest it for 5–10 minutes after baking. This helps the filling settle and makes the shells easier to serve.
How should I store leftovers?
Transfer them to shallow containers and refrigerate within 2 hours. Let the baking dish cool before washing it.
