Can I use frozen shrimp?

Yes and just thaw them fully and pat them dry well before seasoning so they sear instead of steam.

Can I make Cajun Shrimp Pasta less spicy?

Yes and you can reduce the Cajun seasoning a little and skip extra black pepper for a milder sauce.

What pasta works best if I do not have fettuccine?

Linguine and penne and spaghetti all work well because they catch the creamy sauce nicely.

Can I make this ahead for meal prep?

Yes and it reheats well with a small splash of broth or cream to loosen the sauce the next day.

Instructions

Pat the 28 shrimp dry and coat them with Cajun seasoning and smoked paprika and garlic powder and a little salt and pepper so the surface turns from pale and glossy to a deeper red orange with uneven spice coverage. Slice the onion and red pepper into thin strips so the vegetables look loose and irregular rather than neat and identical. The shrimp should sit in a casual layer with some overlap and some heavier spice patches while the sliced vegetables stay separate and visibly fresh. This first change matters because the shrimp now look boldly seasoned and ready for the heat rather than plain and raw.
Cook the fettuccine in salted water until tender so the dry stiff strands change into soft flexible ribbons with a pale glossy finish. The noodles should look relaxed and slightly tangled with uneven curves and natural clumping instead of straight dry sticks. This is the first major structure change in the pasta and it sets up the dish for the creamy sauce later. Save a little pasta water before draining so the final sauce can cling without turning heavy.
Cook the seasoned shrimp in olive oil until they curl and turn opaque with light golden spots and darker red edges. The surface changes from wet and translucent to firm and lightly browned while the spice coating deepens in color. Keep the shrimp in a single uneven layer and remove them as soon as they are cooked through so they stay juicy. This step gives the dish its first real browned flavor and creates a clear contrast from the raw seasoned shrimp in the earlier step.
Add butter and then cook the sliced onion and red pepper until they soften and slump into glossy ribbons while the garlic blends in and disappears between the vegetables. The pan shifts from mostly shrimp marks to a bed of softened vegetables with a warmer orange sheen from the leftover spices. The texture change here is obvious because the vegetables lose their raw stiffness and begin to fold into each other. Their edges turn tender and slightly translucent and the mixture looks richer and more relaxed than the firm slices from the first step.
Pour in the broth and cream and then stir in the parmesan so the pan changes from separate vegetables in fat to a smooth creamy orange sauce with softened vegetables suspended throughout. The cheese melts unevenly at first and then the liquid thickens enough to coat the vegetables in a velvety layer. A squeeze of lemon brightens the sauce so it looks glossy and full rather than flat and heavy. This step creates the main body of the dish and turns the pan into a true pasta sauce instead of a sautéed mixture.
Return the shrimp and add the drained fettuccine so the pale noodles and browned shrimp become fully coated in the creamy orange sauce. The ingredients shift from separate pieces into one dish with sauce clinging to the pasta and shrimp tucked through the noodles with softened peppers and onions woven between the strands. Finish with parsley so the top gets fresh green contrast and the whole dish looks lively and homemade with uneven sauce coverage and irregular twirls and non uniform color. This final change brings the raw preparation and cooked components into one finished Cajun Shrimp Pasta ready for the plate.

Notes

Pro Tips:

Pat the shrimp dry well so the seasoning sticks and the surface browns better.
Reserve a little pasta water so the sauce can loosen without losing flavor.
Grate the parmesan finely so it melts faster into the sauce.
Add the shrimp back only at the end so they stay tender and juicy.

Storage: Let the pasta cool and then store it in an airtight container in the fridge for up to 3 days. The sauce will thicken as it sits and that is normal. Reheat gently with a splash of broth or cream so the noodles loosen and the sauce turns silky again. Avoid high heat because the shrimp can turn firm if warmed too aggressively.
