Creamy Cajun Chicken and Shrimp Stuffed Shells
This is comfort food with a little Cajun swagger. I sear chicken and shrimp hard for that deep char, build a creamy Cajun sauce right in the same pan so nothing gets wasted, then fold the chopped proteins back in and spoon it all into jumbo shells. Pour the rest of the sauce over the top, blanket it with fresh mozzarella, and you've got a rich, cozy dinner that looks like a lot more work than it actually is.
I say it in the video and I'll stand by it here: this is one of my favorite dishes to this day. If you can never decide between chicken and shrimp, this is the dinner that doesn't make you choose — both get seared in the same skillet, both get chopped into the filling, and both end up under that blanket of fresh mozzarella.
The trick worth stealing is the timing on the proteins. Instead of cooking the chicken and shrimp separately, the shrimp goes into the skillet just before the chicken is fully done, and about a minute and a half per side is all it needs — long enough to pick up that char-brown color, short enough that it never turns burnt or overcooked.

The recipe
Creamy Cajun Chicken and Shrimp Stuffed Shells
Ingredients
- 1/2 of a 12-ounce box jumbo pasta shells
- 2 chicken breasts
- Cajun seasoning, to taste (for the chicken)
- salt, to taste (for the chicken)
- 1/2 pound shrimp
- garlic paste, to taste (I never give an exact amount in the video — add it to your liking)
- 1 red bell pepper, diced
- 1 green bell pepper, diced
- 1 large white onion, chopped
- 1 1/2 cups heavy cream
- 1/2 teaspoon garlic powder (for the sauce)
- 1/2 teaspoon salt (for the sauce)
- 1/2 teaspoon Cajun seasoning (for the sauce)
- 1 teaspoon lemon pepper seasoning (for the sauce)
- 1/2 cup shredded Parmesan cheese
- fresh mozzarella cheese, to taste (grated, for topping)
- 2 tablespoons fresh parsley, chopped (optional garnish)
How to Make It
- Boil the jumbo pasta shells (about half of a 12-ounce box) in a pot of boiling water until al dente.
- Drain the shells and blanch them in cold water so they stop cooking and don't get too soft.
- Season the chicken breasts with Cajun seasoning and salt.
- Cook the chicken in a hot skillet until it has a dark brown char on each side.
- Just before the chicken is fully done, add the shrimp to the same skillet.
- Cook the shrimp about 1 1/2 minutes per side, until char-brown but not burnt.
- Remove the chicken and shrimp from the pan and set them aside.
- Add the garlic paste to the same pan.
- Add the red bell pepper, green bell pepper, and white onion to the pan.
- Saute the vegetables for 3 to 5 minutes, until very translucent.
- Slowly pour in 1 1/2 cups heavy cream, scraping up the browned seasoning from the bottom of the pan into the sauce.
- Stir in the garlic powder, salt, Cajun seasoning, and lemon pepper seasoning.
- Bring the sauce to a simmer.
- While the sauce heats, chop the shrimp into medium bite-size pieces — small enough to fit inside a shell, but not too small.
- Chop the chicken into similar bite-size pieces.
- Once the sauce starts to bubble, stir the chopped chicken and shrimp into the sauce and mix well.
- Stir in 1/2 cup Parmesan cheese until the sauce thickens.
- Let the filling cool down before stuffing.
- Spoon the filling into the cooked shells.
- Pour the rest of the sauce over the stuffed shells.
- Grate fresh mozzarella over the top, as much as you like.
- Sprinkle about 2 tablespoons of chopped parsley over the top for garnish, if desired.
Curtis's Tips
- Blanch the cooked shells in cold water — it keeps them from overcooking and getting too soft.
- Season the chicken however you like; I go with Cajun seasoning and salt.
- Look for a nice char-brown color on the shrimp — not burnt or overcooked.
- Cut the shrimp and chicken into nice-size pieces: not too small, not too big, so they fit inside the shells with the rest of the filling.
- Let the filling cool before stuffing the shells. I rushed it once, so learn from my mistake — waiting gives a better texture so the shells aren't runny.
- Add as much mozzarella on top as your heart desires.
- Parsley on top makes it look fancier and adds a minty, nutty taste that pairs well with the dish.
- If you'd rather run a single Creole-style blend in the sauce, try 1 teaspoon Creole seasoning, 1/2 teaspoon black pepper, 1 teaspoon lemon pepper, and 1/2 teaspoon Cajun seasoning instead of the garlic powder plus Cajun combo.
- You can also dice the chicken and shrimp before cooking and sauté them right alongside the onion and bell peppers — either way works, I just like to sear them whole and chop after.
- Want a set, bubbly top? Bake the stuffed shells with the cream sauce and mozzarella until they're hot and golden; otherwise this finishes great straight from the skillet, no oven needed.
Why this works
The move that makes this sauce is the slow pour. The chicken sears with Cajun seasoning and salt until it has a dark brown char, the shrimp follow for about a minute and a half per side, and all of that leaves seasoning stuck to the skillet. When the 1 1/2 cups of heavy cream go in, I add them slowly, lifting every bit off the bottom and into the sauce — flavor you'd throw away with a fresh pan. The half cup of Parmesan is structural: it makes the sauce a lot thicker, which is what stuffing a shell demands. The shells get protected twice, too — blanched in cold water so they stop cooking and don't go too soft, and stuffed only after the filling cools, so the texture sets instead of turning runny.
- Lemon pepper — the zest in the sauce, riding alongside the garlic powder, salt, and Cajun.
- Fresh parsley — a minty, nutty taste that pairs well with the cream, and it makes the plate look better too.
FAQ
Do I have to use heavy cream, or can I use half-and-half?
Heavy cream — 1 1/2 cups, poured in slowly so it picks up all the seasoning off the bottom of the skillet. It's also what the Parmesan thickens into a filling sturdy enough to spoon into shells. It's the only dairy I cook this with in the video, so it's the version I can vouch for — the whole stuffing step is built around that thicker sauce.
My sauce came out thin — what did I miss?
It comes down to two spots in the process: the sauce coming up to a simmer — I wait for a little boil before the chopped chicken and shrimp go back in — and the half cup of Parmesan stirred in at the end, which makes the sauce a lot thicker. And don't stuff hot. I rushed that step once; let the filling cool and the texture sets up so the shells aren't runny.
Can I use Creole seasoning instead of Cajun?
You can build the sauce either way. In the video I use half a teaspoon each of garlic powder, salt, and Cajun seasoning plus a teaspoon of lemon pepper for that zest. If you'd rather run a single Creole-style blend, swap the garlic powder and Cajun combo for 1 teaspoon Creole seasoning, 1/2 teaspoon black pepper, 1 teaspoon lemon pepper, and 1/2 teaspoon Cajun seasoning.
Do the stuffed shells go in the oven?
Not the way I make them in the video — this one finishes on the stovetop: stuff the shells, pour the rest of the sauce over the top, and grate fresh mozzarella over everything, as much as your heart desires. If you want a set, bubbly top, baking the sauced, mozzarella-topped shells until hot and golden works too — no oven required, though.
Why cook the chicken and shrimp whole and chop them after?
The whole breasts build that dark brown char on each side — that color is how I judge they're done — and the shrimp pick up their char-brown color in about a minute and a half per side without tipping into burnt. Chopping afterward lets me cut everything to the size a shell needs: not too small, not too big, so it fits in with the rest of the filling. Dicing the raw chicken and shrimp and sautéing them alongside the onion and bell peppers works too — I just like to sear whole and chop after.
