Creamy Cajun Pasta with Roasted Peppers

My neighbor knocked on my door one evening holding a jar of Cajun seasoning she'd brought back from New Orleans. She said it was too spicy for her pantry but too good to waste. I tossed it with cream, roasted peppers, and whatever pasta I had on hand, and the kitchen smelled like a backstreet bistro I'd never visited. That improvised dinner turned into this recipe, one I now make when I want comfort with a little fire.

I made this for a potluck once, and someone asked if I'd ordered it from a restaurant. I laughed because I'd been rushing, tasting the sauce straight from the spoon between stirring. It's become my go-to when I want to look like I tried harder than I did. The compliments always feel better than the effort it takes.

Ingredients

• Penne or fettuccine (350 g): Penne holds the sauce in its ridges, fettuccine wraps it around like a ribbon; both work beautifully, so pick what you're craving.
• Red bell peppers (2 large, roasted): Roasting them yourself makes them smoky and sweet; jarred ones work in a pinch, just drain them well.
• Yellow onion (1 small, finely chopped): It melts into the sauce and adds a gentle base that balances the boldness of the Cajun spices.
• Garlic (2 cloves, minced): Fresh garlic blooms in the oil and makes the whole kitchen smell like anticipation.
• Olive oil (2 tbsp): It carries the spices and keeps everything from sticking; don't skimp or the flavors won't release properly.
• Cajun seasoning (1 tbsp): This is the heart of the dish; taste it first so you know how much heat you're working with.
• Smoked paprika (1 tsp): It adds depth and a whisper of campfire without any actual spice.
• Heavy cream (200 ml): The richness that turns this into comfort food; it thickens as it simmers and coats the pasta like silk.
• Vegetable broth (60 ml): It loosens the sauce just enough and adds a savory backbone that cream alone can't provide.
• Parmesan cheese (60 g, freshly grated): Grate it yourself; pre-grated doesn't melt the same and the sauce won't be as smooth.
• Fresh parsley (2 tbsp, chopped): A handful of green at the end makes it look alive and taste brighter.
• Salt and black pepper: Season at the end after the Parmesan goes in, or you might overdo it.

Instructions

Boil the pasta:

Cook your pasta in heavily salted water until it still has a little bite. Reserve half a cup of the starchy water before you drain; it's your secret weapon for adjusting the sauce later.

Sauté the aromatics:

Heat the olive oil over medium heat and add the onion, stirring until it softens and turns translucent, about three minutes. Toss in the garlic and let it sizzle for a minute until your kitchen smells incredible.

Bloom the spices:

Stir in the Cajun seasoning and smoked paprika, letting them toast for thirty seconds. This step wakes up the flavors and keeps them from tasting raw or dusty.

Add the peppers:

Toss in the roasted bell peppers and sauté for two minutes so they soak up the spices. They'll start to glisten and smell sweet.

Build the sauce:

Pour in the cream and broth, stirring everything together. Let it simmer gently for three to four minutes until it thickens just a little and coats the back of your spoon.

Stir in the cheese:

Add the Parmesan, salt, and pepper, stirring until the cheese melts into the sauce and it turns glossy. If it looks too thick, splash in some reserved pasta water a little at a time.

Toss and serve:

Add the drained pasta to the skillet and toss it with the sauce until every piece is coated. Let it warm together for a minute or two, then serve hot with parsley and extra cheese on top.

Pin It

I served this to a friend who doesn't usually like spicy food. She ate two bowls and asked for the recipe, which told me the sweetness of the peppers really does soften the heat. It's the kind of dish that surprises people, including yourself, every time you make it.

Making It Your Own

This pasta loves protein. I've stirred in sliced grilled chicken, pan-seared shrimp, and even crumbled Italian sausage, and each version felt like a different meal. If you want it vegetarian, leave it as is; if you want it hearty, toss in whatever cooked meat you have on hand. The sauce is forgiving and stretches to fit.

Storage and Reheating

Leftovers keep in the fridge for up to three days, though the sauce thickens as it sits. When you reheat it, add a splash of broth or cream and warm it gently on the stove, stirring until it loosens back up. Microwaving works in a pinch, but the stovetop brings the creaminess back to life. I've never had leftovers last longer than two days, if I'm being honest.

Pairing and Serving Suggestions

This pasta is rich, so I like to serve it with something crisp and green. A simple arugula salad with lemon and olive oil cuts through the cream, and garlic bread is never a bad idea if you're feeding a crowd. A cold Sauvignon Blanc or a light Pinot Noir works beautifully if you're pouring wine.

• Add a handful of spinach or kale to the sauce in the last minute for extra greens.
• Swap fettuccine for rigatoni if you want more sauce trapped inside each bite.
• Finish with a squeeze of lemon juice for brightness if the dish feels too heavy.

This dish has become one of those recipes I make without thinking, the kind that feels like muscle memory. I hope it finds a spot in your rotation too.

Recipe Q&A

→ Can I make this dish ahead of time?

Yes, you can prepare the sauce up to 2 days in advance and store it in the refrigerator. Reheat gently over low heat before tossing with fresh pasta. Cook the pasta just before serving to maintain its texture.

→ What pasta shapes work best with this sauce?

Penne and fettuccine are ideal because their ridged or flat surfaces catch the creamy sauce beautifully. Rigatoni, linguine, or even farfalle also work well. Avoid thin pasta like angel hair, which can clump.

→ How can I adjust the spice level?

Start with 1 tablespoon of Cajun seasoning and add more gradually to taste. You can also reduce the smoked paprika or omit it entirely for a milder version. Fresh chili flakes can intensify heat if desired.

→ What proteins pair well with this dish?

Grilled or pan-seared chicken breast, shrimp, or andouille sausage complement the Cajun flavors beautifully. Add cooked proteins in step 8 when tossing with the pasta.

→ Can I substitute the heavy cream?

Yes. Use half-and-half for a lighter version, or substitute with coconut milk or cashew cream for a dairy-free option. The sauce will have a slightly different texture but remains delicious.

→ Why is the sauce too thick or thin?

If too thick, add reserved pasta water one tablespoon at a time until you reach desired consistency. If too thin, simmer an additional 2-3 minutes. The sauce should coat the pasta without pooling at the bottom of the bowl.
