This One Pot Creamy Cajun Shrimp is pure comfort in a skillet. It has the kind of bold, cozy flavor that makes a regular weeknight dinner feel special, yet it still comes together fast enough for a busy day. I love meals like this because they taste like you spent all afternoon cooking, even though the pot does most of the work.
What makes it so good is the mix of simple, familiar ingredients. You get 12 ounces penne pasta, uncooked, 1 1/2 pounds large shrimp (16/20 count), peeled and deveined, and 2 tablespoons Cajun seasoning, divided for that warm, smoky kick. Then come 2 tablespoons olive oil, 1 medium yellow onion, diced, 1 red bell pepper, diced, and 3 cloves garlic, minced for a strong base of flavor. The sauce builds with 1 (14.5-ounce) can diced tomatoes, undrained, 3 cups low-sodium chicken broth, 1 cup heavy cream, and 1 cup shredded Monterey Jack cheese. A little kosher salt, to taste finishes it off, while chopped fresh parsley, extra Cajun seasoning, and lemon wedges make a bright, fresh garnish. The flavor is creamy, savory, gently spicy, and just a little tangy from the tomatoes and lemon.
Best of all, this recipe is wonderfully easy to make. First, you season the shrimp, then cook the vegetables, pasta, and sauce all in one pot. Because the pasta cooks right in the broth and tomato mixture, it absorbs flavor as it softens. After that, you stir in the cream and cheese, add the shrimp, and let everything finish together. The timing is simple too, with 15 minutes of prep, 25 minutes of cooking, and a total time of 40 minutes. It makes 4 servings and comes in at about 520 calories per serving, which makes it a practical choice for a full dinner.
This is the kind of meal that fits so many moments. It is perfect for chilly nights, busy evenings, or anytime you want something warm and filling without making a sink full of dishes. It also works well for small family dinners, casual guests, or even a cozy date night at home.

Shrimp Tips
For the best One Pot Creamy Cajun Shrimp, start with large shrimp that are already peeled and deveined, because that saves time and keeps dinner easy. If you can, choose shrimp that look firm and smell clean, not fishy. Also, pat them dry before seasoning so the Cajun spice sticks well and the shrimp sear and cook more evenly. Since shrimp cook fast, keep a close eye on them near the end. They are ready as soon as they turn pink and opaque. If you cook them too long, they can turn rubbery, so a gentle finish is best. If using frozen shrimp, thaw them fully first and drain any extra water before cooking.
Options for Substitutions
- Use rotini, rigatoni, or fettuccine instead of penne if that is what you have on hand.
- Swap the shrimp for chicken breast, cut into small pieces, if you want a different protein.
- Replace the Monterey Jack cheese with cheddar, Colby Jack, or a mild Pepper Jack for extra heat.
- Use vegetable broth instead of chicken broth if you prefer a lighter or meat-free base.
- Trade the heavy cream for half-and-half if you want a slightly lighter sauce, though it will be less rich.
- Add extra vegetables like spinach, mushrooms, or zucchini to stretch the meal and add color.
Watch Out for These Mistakes
One of the biggest mistakes is overcooking the shrimp. Since shrimp are small and delicate, they do not need much time in the pot. In fact, they should only cook until they turn pink and opaque. If you leave them in too long, they can get tough and chewy, which takes away from the creamy texture of the dish.
Another common issue is not stirring the pasta enough while it simmers. Because the pasta cooks in the same pot with the broth and tomatoes, it can stick to the bottom if left alone for too long. So, stir every so often and make sure the pasta stays mostly submerged. If the mixture looks too dry before the pasta is done, add a little more broth.
Also, be careful with the salt. Cajun seasoning often already contains salt, so it is smart to taste before adding more at the end. Since the cheese and broth also add flavor, you may need very little extra salt. This is especially important if you are using a store-bought Cajun blend that runs salty.
Finally, do not add the cream and cheese too early. They should go in after the pasta has mostly cooked, because too much heat for too long can make the sauce separate or become grainy. Instead, stir them in near the end so the sauce turns smooth and creamy.
What to Serve With One Pot Creamy Cajun Shrimp?
This dish is rich and filling, so the best sides are simple and fresh. A green salad with a light vinaigrette works well because it cuts through the creaminess. Garlic bread is another favorite, since it is perfect for scooping up extra sauce. If you want a vegetable, try roasted broccoli or steamed green beans for balance. You could also serve warm cornbread if you want a more Southern-style dinner.
Storage Instructions
Store: Place leftovers in an airtight container and refrigerate for up to 2 days. Because this recipe contains shrimp and cream, it is best eaten sooner rather than later.
Freeze: Freezing is not ideal for this dish, since the cream sauce and shrimp can change texture after thawing. However, if needed, freeze for up to 1 month in a freezer-safe container. For the best result, thaw in the fridge overnight.
Reheat: Warm leftovers gently on the stovetop over low heat with a splash of broth or milk. Stir often and stop heating as soon as it is hot. If using a microwave, heat in short intervals at medium power, stirring between each round. This helps keep the shrimp from turning tough.

Step-by-Step Instructions
Step 1: Season the Shrimp
Pat the shrimp dry with paper towels, then toss them with 1 tablespoon of the Cajun seasoning until they are evenly coated. Set them aside while you build the base of the dish. This quick step helps the shrimp take on flavor right from the start.
Step 2: Soften the Vegetables
Heat the olive oil in a large deep skillet or Dutch oven over medium heat. Add the onion and bell pepper, then cook for 5 to 6 minutes until they soften. After that, add the garlic and the remaining tablespoon of Cajun seasoning, and cook for 30 to 60 seconds until fragrant. Keep stirring so the garlic does not burn.
Step 3: Cook the Pasta in the Same Pot
Add the diced tomatoes with their juice, the chicken broth, and the uncooked pasta. Stir well so the pasta is mostly submerged. Bring the pot to a boil, then lower the heat to a simmer, cover, and cook for 14 to 16 minutes. Stir now and then so the pasta does not stick, and continue until it is al dente and most of the liquid is absorbed.
Step 4: Make It Creamy
Stir in the heavy cream and shredded Monterey Jack cheese. Let it cook for 2 to 3 minutes, just until the cheese melts and the sauce becomes smooth and creamy. At this point, the dish should smell rich, warm, and full of Cajun flavor.
Step 5: Add the Shrimp and Finish
Nestle the seasoned shrimp into the pasta mixture. Cover the pot and cook for 5 to 6 minutes, until the shrimp are pink and opaque throughout. Do not overcook them, since shrimp can turn rubbery very quickly. Finally, taste the dish and add kosher salt if needed. Garnish with parsley, a little extra Cajun seasoning, and lemon wedges before serving hot.
