Ten ingredients and forty minutes in a single wide pot. There is no colander in this recipe.
The chicken is browned first and taken out, so its spice crust survives. It goes back in only at the end.
Why This Recipe Works
- Browning the chicken first builds a crust that simmering would have washed off.
- Cooking the shells in broth and half-and-half means the starch stays in the sauce.
- Stirring often is what stops pasta catching on a pot with dairy in it.
- Stopping at al dente leaves the liquid as a thin coating rather than a paste.
- Parmesan stirred in at the end thickens without needing a reduction.
Ingredient Notes
- Medium shell pasta
- Eight ounces. Shells are the shape here — there is no elbow macaroni in this recipe despite what the name suggests.
- Half-and-half
- A cup, with two cups of broth. Lighter than cream, which is why the finished sauce coats thinly rather than pooling.
- Cajun seasoning
- Two teaspoons, all of it on the chicken. The sauce gets its colour from smoked paprika instead.
- Grated Parmesan
- Half a cup, stirred in at the end. It thickens the liquid without a long reduction that would overcook the shells.
How to Make It
Cajun crust, browned to 165F, then out
Season chicken with Cajun seasoning. Heat oil in a wide pot and brown chicken until crusted; remove when it reaches 165 degrees Fahrenheit.
Broth and half-and-half, then the shells
Add broth and half-and-half to the same pot and bring to a gentle simmer. Stir in shell pasta.
Stir often, to al dente and a thin cream
Cook, stirring often, until shells are al dente and the liquid becomes a thin light-orange cream coating.
Parmesan and paprika, chicken back
Stir in Parmesan, paprika, and black pepper. Return the chicken and warm through.
Parsley, and nothing else in it
Finish with parsley. Do not add cashew cream, tomato pieces, bell pepper, sausage, or elbow macaroni.
One Pot, and Why the Chicken Leaves It
A one-pot pasta is really a sequence problem: everything shares a pot, so the order decides what survives. Each rung below is the reason its step happens where it does.
Crust the chicken while the pot is drybrowned and crusted, out at 165F
1 1/4 lb of breast chunks with 2 tsp of Cajun seasoning - ALL of it, on the meat - browned in 1 tbsp of oil until CRUSTED. There is no liquid in the pot yet, and that is the only window a spice crust gets. That crust is what keeps this from tasting like chicken poached in its own sauce.
Take it out - the pot is needed for something else
Removed the moment it reads 165F. Left in, it would sit through the pasta's whole simmer and both dry out and lose its crust to the liquid. This is the step that makes the rest possible.
The cooking liquid IS the saucegentle simmer, not a boil
2 cups of low-sodium broth and 1 cup of HALF-AND-HALF brought to a gentle simmer, then 8 oz of medium shells stirred in. No separate pot of water and no draining: the starch that would go down the sink stays here and is what thickens the sauce. Half-and-half rather than cream is why the result coats thinly instead of pooling.
Stir often, and stop at al denteal dente, liquid a thin coating
Stirring is not optional with dairy and pasta starch in the same pot - both catch on a hot base. And al dente is the stopping point for the LIQUID as much as the pasta: cooked further, a thin light-orange cream reduces into a paste and the shells go soft in it.
Thicken and reunite, off the clock
1/2 cup of Parmesan, 1/2 tsp smoked paprika and 1/4 tsp pepper stirred through, then the chicken back in just to WARM THROUGH. The Parmesan thickens without another minute of reduction, and the paprika is where the sauce's colour comes from - the Cajun seasoning all went on the meat. Step 5 leaves out cashew cream, tomato, bell pepper, sausage and elbow macaroni.
Success Tips
- Take the chicken out once it is browned — it goes back in at the very end.
- Stir often; dairy and pasta starch catch on a pot base quickly.
- Stop at al dente. The shells keep softening in a hot sauce.
Serving Ideas
Four servings in pale bowls, the shells in their thin light-orange cream with the browned Cajun chicken over them, finished with grated Parmesan, cracked black pepper and chopped parsley.
Frequently Asked Questions
What is a shellbow?
The pasta shape here is medium shells. There is no elbow macaroni in it.
Can I cook the chicken in the sauce?
It would lose the spice crust the finished dish shows. Step 1 browns it and takes it out; it returns in step 4 to warm through.
How is this different from the other Cajun chicken pastas?
One is built on a dairy-free cashew cream and one is deliberately sauceless with tomato and bell pepper. This is a one-pot half-and-half sauce with neither.
