Classic Creamy Jambalaya Pasta

Here is my favorite creamy jambalaya pasta recipe, with tender shrimp, smoky sausage, colorful peppers, and fettuccine all tossed in a rich Cajun cream sauce with melted gruyere.

This pasta is what I make when I’m craving something with a little kick but still want that comfort food feel. It’s got all those classic jambalaya flavors but in a creamy pasta form that my family can’t get enough of.

What Kind of Shrimp Should I Use?

For this jambalaya pasta, you’ll want to use medium to large shrimp that are already peeled and deveined to save yourself some prep time. Fresh shrimp is great if you can get it, but frozen shrimp works just as well and is often more budget-friendly – just make sure to thaw it completely and pat it dry before cooking. If you’re at the seafood counter and not sure what size to grab, look for shrimp labeled 31-40 count or 21-30 count per pound, which are perfect for this kind of dish. Raw shrimp is preferred over pre-cooked since it’ll soak up all those cajun flavors as it cooks in the sauce.

Options for Substitutions

This jambalaya pasta is pretty forgiving when it comes to swaps:

• Fettucine: Any long pasta works great here – try linguine, pappardelle, or even penne if that’s what you have in the pantry.
• Shrimp: You can use chicken breast cut into bite-sized pieces instead. Just cook it a bit longer until it reaches 165°F internally.
• Sausage: Andouille sausage is traditional for jambalaya, but kielbasa, chorizo, or even Italian sausage will work. If you can’t find any smoked sausage, regular breakfast sausage adds good flavor too.
• Gruyere: This cheese can be pricey, so feel free to use sharp white cheddar, fontina, or even a mix of mozzarella and parmesan for a more budget-friendly option.
• Heavy cream: Half-and-half works if you want to lighten things up, though the sauce will be slightly thinner. You can also use whole milk mixed with 2 tablespoons of cream cheese to add back some richness.
• Bell peppers: Use whatever color peppers you have on hand – the mix of green and red is just for color variety.
• Cherry tomatoes: A 14.5 oz can of diced tomatoes (drained) works just as well if fresh tomatoes aren’t available.

Watch Out for These Mistakes While Cooking

The biggest mistake with this creamy jambalaya pasta is overcooking the shrimp, which turns them rubbery and tough – pull them from the heat as soon as they turn pink and curl slightly, since they’ll cook a bit more when you add them back to the sauce at the end.

Another common error is adding the cheese while the cream is still boiling, which can cause it to separate and become grainy instead of smooth, so make sure to turn off the heat first and stir the gruyere in gradually.

Don’t skip saving that pasta water before draining – those starchy few tablespoons help the sauce cling to the noodles and bring everything together, making the difference between a creamy dish and a dry one.

Finally, go easy on the cajun seasoning at first since brands vary wildly in heat level, and you can always add more at the end but you can’t take it away.

What to Serve With Jambalaya Pasta?

This creamy jambalaya pasta is pretty hearty on its own, but I love serving it with some crusty French bread or garlic bread to soak up all that amazing cajun cream sauce. A simple side salad with crisp romaine, cucumber, and a light vinaigrette helps balance out the richness of the dish and adds a refreshing crunch. If you want to lean into the Southern vibe, cornbread muffins are another great option that pair really well with the spicy, creamy flavors. For drinks, I’d go with a cold beer or sweet iced tea to cool things down if the cajun seasoning brings the heat.

Storage Instructions

Store: Keep your leftover jambalaya pasta in an airtight container in the fridge for up to 3 days. The cream sauce might thicken up a bit as it sits, but that’s totally normal. I actually think the flavors get even better the next day after everything has had time to meld together.

Freeze: While you can freeze this pasta for up to 2 months, just know that cream-based sauces sometimes separate a bit when thawed. If you do freeze it, portion it out in freezer-safe containers so you can grab individual servings whenever you need them.

Reheat: Warm it up gently on the stovetop over medium-low heat, adding a splash of cream or milk to loosen the sauce. You can also microwave it in 30-second intervals, stirring between each one. Just be careful not to overcook the shrimp or it’ll get rubbery.

• Calories: 3400-3700
• Protein: 160-180 g
• Fat: 190-210 g
• Carbohydrates: 220-250 g

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: Prepare Mise en Place and Start 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: Sear Shrimp and Build Aromatics

• 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: Deglaze and Create Sauce Base

• 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: Incorporate Cheese and Season

• 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: Combine All Components and Finish

• 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.
