How to Make Creamy Cajun Shrimp Crab Pasta

Here is exactly how we make this creamy cajun shrimp crab pasta: about 15 minutes of prep and roughly 30 minutes of cooking.

What you need: Large Skillet, Large Pot, Colander.

1. Bring a large pot of salted water to a boil. Cook pasta according to package directions until al dente. Reserve 1/2 cup of pasta water, then drain and set aside.
2. In a large skillet over medium-high heat, combine 1 tbsp butter and 1 tbsp olive oil. Add shrimp in a single layer and sear for 1 to 2 minutes per side until pink and opaque. Transfer to a plate and set aside.
3. In the same pan, add crab meat and warm for 1 minute. Remove and set aside with shrimp.
4. Reduce heat to medium. Add remaining butter and olive oil. Saute onion and bell pepper for 4 to 5 minutes until soft. Stir in garlic and cook 30 seconds.
5. Add Cajun seasoning and stir for 1 minute to bloom the spices.
6. Pour in chicken broth and scrape up browned bits. Simmer 2 minutes until reduced.
7. Stir in stock, then slowly pour in heavy cream. Add crushed tomatoes if using. Bring to a gentle simmer and cook 5 to 7 minutes until slightly thickened.
8. Stir in Parmesan cheese until melted. Return shrimp and crab to the pan. Simmer 2 to 3 minutes to reheat.
9. Add lemon juice, red pepper flakes, salt, and pepper. Taste and adjust seasoning.
10. Add cooked pasta and toss to coat. Add reserved pasta water as needed for creaminess.
11. Remove from heat. Garnish with green onions or parsley and extra Parmesan.
12. Serve immediately with crusty bread.

That is the whole method. Nothing here needs special technique, just a little attention at the right moments.

Tips for the Best Creamy Cajun Shrimp Crab Pasta

None of this is complicated, but these are the small habits that separate a good plate of this creamy cajun shrimp crab pasta from a great one.

• Get the pan properly hot before anything goes in. That first sear is where the flavor starts.
• Do not move the food too soon. Let it sit long enough to release on its own.
• Scrape up the browned bits when you add liquid. That is pure flavor sitting on the bottom.
• Read the steps once before you start. Knowing what is coming makes the whole thing calmer.
• Have everything measured and within reach before the heat goes on. Have everything measured and within reach before the heat goes on.

Taste as you go and adjust the seasoning at the end rather than the beginning. This creamy cajun shrimp crab pasta rewards a little attention right at the finish.

Variations and Add Ins

Creamy cajun shrimp crab pasta takes changes well, so treat the recipe above as a starting point rather than a set of rules. These are the swaps we come back to most often.

• Use a different fish. Any firm white fish works, so buy whatever looks best that day.
• Add citrus. A squeeze of lemon or lime right at the end wakes everything up.
• Make it creamy. A splash of cream or a spoonful of cream cheese turns it into comfort food.
• Add herbs. Fresh dill, parsley or basil brighten the whole plate.
• Change the herbs. Fresh parsley, basil or dill at the end each send it somewhere slightly different for no extra effort.
• Make it a bigger meal. Serve it over rice or with warm bread and it stretches to feed another person or two.

Change one thing at a time rather than three. That way you find out what you actually like in this recipe instead of guessing at the end.

How to Store and Reheat Creamy Cajun Shrimp Crab Pasta

Seafood is best the day it is made, but leftovers keep in an airtight container in the refrigerator for up to two days. Reheat gently and briefly, since seafood turns firm quickly with too much heat.

If you are cooking ahead on purpose, prep the components and keep them separate until you are ready. It takes a few minutes off a busy evening and this dish holds its texture far better that way.
