Jambalaya OR creamy pasta. Couldn’t pick. Wouldn’t pick.
So both. Same skillet. Same night. ON PURPOSE.
Smoky sausage, cajun shrimp, peppers, tomatoes, all tangled up with fettuccine in this silky gruyere cream sauce that melts into every single noodle. The cajun seasoning does the heavy lifting here (warm, smoky, a little heat to keep the cream from feeling too rich).
It’s two dinners in one. The kind of thing you make on a Wednesday and immediately start plotting a Friday encore.
What Makes It a Jambalaya Pasta?
Jambalaya meets pasta…. and honestly, it’s a mashup that just WORKS.
- The HOLY TRINITY (onion, green pepper, red pepper) does the heavy lifting as your flavor base
- Cajun seasoning + smoked paprika bring that smoky, Louisiana-style depth
- Sausage rounds + shrimp deliver the protein punch jambalaya is famous for
- Cherry tomatoes add acidity (just like traditional jambalaya’s tomato base)
- Heavy cream + gruyere? That’s the PASTA part. Creamy, cheesy, indulgent
- Fettuccine swaps in for rice…. wider noodles grip that rich sauce beautifully
How to Keep the Cream Sauce Silky
SIMMER the cream gently. Do not let it boil rapidly, or you risk breaking the sauce and separation.
Take the skillet OFF THE HEAT before adding cheese. Residual heat melts it smoothly, no lumps!
Always use FRESHLY GRATED cheese. Pre-grated stuff won’t melt as silky.
Reserved pasta water is your secret weapon. The starch emulsifies the cream and keeps everything smooth.
Storing & Reheating Leftovers
- Fridge within TWO hours, airtight container. Eat within THREE days (*shrimp runs the clock*
- Reheat LOW and slow on the stove with a splash of cream to revive the sauce….stir constantly
- Microwave only if desperate (rubbery shrimp alert!). Top with fresh parsley
Fridge fast, reheat gentle, cream stays dreamy.

Ingredients
For the pasta:
- 12 oz fettuccine (I always use Barilla for the perfect al dente texture)
- 3 tbsp parsley
For the sauce and protein:
- 1 lb shrimp
- 3 tbsp butter (I like Kerrygold unsalted butter for this)
- 3 tbsp cajun seasoning
- 8 oz sausage (sliced into 1/4-inch rounds)
- 1 large onion
- 1 green pepper (diced into 1/2-inch pieces)
- 1/2 red pepper
- 5 garlic cloves (freshly minced for best flavor)
- 1 pint cherry tomatoes
- 2 cups heavy cream
- 8 oz gruyere (freshly grated for a smoother melt)
- 1/4 tsp smoked paprika
Step 1: Prep Ingredients and Boil Pasta
- 1 large onion, diced
- 1 green pepper, diced into 1/2-inch pieces
- 1/2 red pepper, diced into 1/2-inch pieces
- 5 garlic cloves, freshly minced
- 1 pint cherry tomatoes, halved
- 8 oz sausage, sliced into 1/4-inch rounds
- 12 oz fettuccine
Dice the onion into medium pieces, cut the green and red peppers into 1/2-inch pieces, mince the garlic cloves fresh, halve the cherry tomatoes, and slice the sausage into 1/4-inch rounds.
Bring a large pot of salted water to a boil and add the fettuccine, cooking it according to package directions until al dente.
Reserve 1/2 cup of pasta water before draining.
I like to reserve the pasta water in a measuring cup so I can control exactly how much I add to the sauce—it helps achieve the perfect creamy consistency without making it too thin.
Step 2: Brown Shrimp and Sausage
- 3 tbsp butter
- 1 lb shrimp
- 3 tbsp cajun seasoning
- 8 oz sausage from Step 1
- 1 large onion, diced from Step 1
- 1 green pepper, diced from Step 1
- 1/2 red pepper, diced from Step 1
Melt the butter in a large, deep skillet or Dutch oven over medium-high heat.
Pat the shrimp dry and season them generously with the cajun seasoning.
Sear the shrimp for 1-2 minutes per side until just cooked through and starting to turn pink, then transfer to a plate.
In the same skillet, add the sliced sausage and cook for 3-4 minutes until browned on the edges.
Add the diced onion and peppers, cooking for 4-5 minutes until they soften slightly and start to caramelize.
This builds a flavorful foundation by allowing the vegetables to pick up the browned bits left from the shrimp and sausage.
Step 3: Simmer Aromatics and Cream
- 5 garlic cloves, freshly minced from Step 1
- 1 pint cherry tomatoes, halved from Step 1
- 2 cups heavy cream
Add the minced garlic to the skillet and cook for 30 seconds until fragrant.
Stir in the halved cherry tomatoes and cook for 3-4 minutes until they begin to soften and release their juice.
Pour in the heavy cream and bring to a gentle simmer, stirring occasionally.
Let the cream reduce for 2-3 minutes until it thickens slightly—you’re looking for it to coat the back of a spoon lightly.
I find that simmering the cream gently rather than boiling it rapidly gives a smoother, silkier texture that won’t break or separate.
Step 4: Melt Gruyere into Sauce
- 8 oz gruyere, freshly grated
- 1/4 tsp smoked paprika
Remove the skillet from heat and immediately stir in the freshly grated Gruyere cheese and smoked paprika until the cheese is completely melted and incorporated.
The residual heat will melt the cheese smoothly without any lumps.
Taste and adjust seasoning as needed—the cajun seasoning and smoked paprika provide depth, but you may want a pinch more salt or pepper depending on your preference.
Step 5: Toss Everything Together
- 12 oz cooked fettuccine from Step 1
- 1 lb cooked shrimp from Step 2
- 1/2 cup reserved pasta water from Step 1
- 3 tbsp parsley
Add the cooked fettuccine from Step 1 to the sauce and gently toss to coat evenly.
Return the shrimp from Step 2 to the skillet along with half of the reserved pasta water, stirring gently to incorporate without breaking up the shrimp.
Add the parsley and toss once more.
If the sauce seems too thick, add the remaining pasta water a tablespoon at a time until you reach your desired consistency—the starch in the pasta water helps emulsify the cream sauce and prevents it from becoming heavy.
Serve immediately while piping hot.

Authentic “holy trinity” is onion, green pepper, and celery. No red pepper.
