Steak with Cajun shrimp sauce is a quick skillet surf-and-turf dinner for two. A New York strip develops a deep seared crust, large shrimp cook in the same flavorful pan, and a cream sauce made with Dijon, Parmesan, Cajun seasoning, lemon, and parsley ties them together.
The complete recipe takes about 25 minutes. Its success depends on cooking the steak and shrimp separately, resting the beef, and finishing the Parmesan sauce away from direct heat so every component keeps the right texture.
Ingredients for Steak with Cajun Shrimp Sauce
Use 1 pound New York strip steak, 24 large raw deveined shrimp, and 3 tablespoons butter divided across the cooking stages. The sauce needs 1 cup heavy cream, 1/4 cup chicken broth, 1/4 cup freshly grated Parmesan, 2 tablespoons Dijon mustard, 2 teaspoons minced garlic, 1 teaspoon Cajun seasoning, 1 tablespoon lemon juice, and 1 tablespoon chopped fresh parsley.
- New York strip: Its balance of tenderness and beefy flavor suits a fast skillet sear.
- Large shrimp: Raw, deveined shrimp are easier to judge than precooked shrimp and stay juicier.
- Dijon mustard: It brings tang and helps the cream sauce taste balanced rather than heavy.
- Cajun seasoning: Brands vary in salt and heat, so taste before adding extra salt.
- Fresh Parmesan: Grate it finely so it melts quickly after the skillet leaves the heat.

How to Make Steak with Cajun Shrimp Sauce
- Sear the steak. Melt 1 tablespoon butter in a large skillet over medium-high heat. Sear the steak about 4 to 5 minutes per side for medium-rare, or until it reaches your preferred doneness.
- Rest the beef. Move the steak to a board and leave it undisturbed while the shrimp and sauce cook.
- Cook the shrimp. Lower the heat to medium and melt another tablespoon butter. Add shrimp in a single layer and cook 1 to 2 minutes per side, just until pink and opaque. Transfer them beside the steak.
- Bloom the garlic. Add the final tablespoon butter and cook minced garlic for about 1 minute without browning it.
- Start the sauce. Pour in chicken broth and stir to lift the browned bits. Add cream, Dijon, and Cajun seasoning. Bring to a boil, then simmer about 1 minute.
- Add Parmesan off heat. Remove the skillet from the burner and stir in Parmesan until smooth.
- Finish. Add lemon juice, parsley, and cooked shrimp. Slice the rested steak and spoon the warm Cajun shrimp sauce over it.

Prepare for a Strong Sear
Pat the steak dry before it reaches the skillet. Surface moisture must evaporate before browning can begin, so a dry steak develops color faster and spends less time overcooking inside.
Let the skillet heat before adding butter and steak. Once the meat is down, avoid sliding it around. Turn when it releases easily and a dark crust has formed.

Judge Steak by Temperature
The suggested 4 to 5 minutes per side is a guide for medium-rare, but thickness and skillet temperature change the timing. An instant-read thermometer is more dependable. Account for a small rise in temperature while the steak rests.
Resting is not optional here. It gives the juices time to redistribute and creates the window needed to cook shrimp and sauce without rushing.
Use the Flavor Left in the Skillet
The brown residue from steak and shrimp is the foundation of the sauce. After the garlic becomes fragrant, add chicken broth and scrape the skillet with a wooden spoon. Those dissolved bits provide savory depth without another ingredient.
Keep the garlic pale. Burned garlic will make the entire cream sauce bitter, and no amount of Parmesan can hide it.
Make a Smooth Cajun Cream Sauce
Whisk cream, Dijon, and Cajun seasoning into the broth and let the mixture simmer only long enough to begin thickening. A one-minute simmer keeps the sauce pourable and reduces the risk of the cream separating.
Remove the pan from direct heat before stirring in finely grated Parmesan. Add the lemon juice after the cheese has melted; the acidity brightens the rich sauce without interfering with the initial melt.
Balance the Cajun Seasoning
Use 1 teaspoon as written the first time. Some blends are mostly herbs and pepper, while others contain considerable salt and cayenne. Taste the finished sauce before increasing it.
If the sauce tastes too intense, loosen it with a small splash of cream or broth. If it feels too rich, an extra squeeze of lemon provides contrast without making it thin.
Serving Ideas
Mashed potatoes, rice, or crusty bread catch every bit of Cajun cream sauce. For a lighter plate, add roasted asparagus, green beans, broccoli, or a crisp salad.
Slice the steak against the grain just before serving. Fan the pieces on warm plates, arrange the shrimp across them, and spoon over enough sauce to coat without hiding the seared crust.
Plan the Timing
Measure the sauce ingredients and grate the Parmesan before the skillet heats. Once the steak begins resting, the shrimp and sauce move quickly, and stopping to measure can leave the seafood sitting too long.
Use the same warm plate for the steak and cooked shrimp, but keep the shrimp beside rather than under the beef so their juices do not soften its crust. Start the sauce immediately after removing them. By the time the sauce is smooth, the steak has had an adequate rest and everything can reach the table hot.
Storage and Reheating
This dish is best freshly cooked. If needed, refrigerate steak, shrimp, and sauce airtight for up to 2 days. Reheat the sauce slowly over low heat and add a splash of broth if it thickens.
Warm steak and shrimp only until heated through. High heat makes the beef tougher, causes shrimp to turn rubbery, and can split the cream sauce.
Conclusion
Sear a New York strip in butter and let it rest. Cook shrimp briefly in the same skillet and remove. Sauté garlic, deglaze with broth, and simmer cream, Dijon, and Cajun seasoning for 1 minute. Stir in Parmesan off heat, then add lemon, parsley, and shrimp before spooning the sauce over sliced steak.
Frequently Asked Questions
- → How do I keep the shrimp from becoming rubbery?
Cook them only 1 to 2 minutes per side, remove as soon as they are opaque, and return them only briefly to the finished sauce.
- → Why should Parmesan go in off the heat?
Lower heat helps finely grated Parmesan melt smoothly and reduces the chance of a grainy or separated cream sauce.
- → Can I make the Cajun shrimp sauce less spicy?
Start with less Cajun seasoning and increase after tasting. A splash of cream can soften a sauce that is already too hot.
- → What should I serve with steak and Cajun shrimp sauce?
Mashed potatoes, rice, or crusty bread are ideal for the sauce, while asparagus or a crisp salad adds freshness.
