Ingredients List

Here’s what you’ll need—and yes, you probably have half of it already:

1 lb large shrimp (peeled, deveined, tails on or off—your call)
8 oz fettuccine (or linguine, spaghetti, penne—just don’t use angel hair)
1 tbsp Cajun seasoning (store-bought is fine, homemade is better)
1 cup heavy cream
1 bell pepper (sliced thin—any color works)

Step-by-Step Instructions (The Right Way, with Real Kitchen Logic)

Cajun shrimp over creamy fettuccine with peppers and fresh herbs

Step 1: Prep Like a Pro (Before You Touch Heat)

What to do: Peel and devein your shrimp (keep the tails on if you like a little flair), slice your bell peppers into thin strips, mince your garlic, and measure out the cream, Parmesan, butter, and Cajun seasoning.
Why it matters: This dish cooks fast. You don’t want to be scrambling with a garlic press while your shrimp are overcooking. Having everything prepped makes your cooking smooth, not chaotic.

Chef Insight: Pat your shrimp dry with paper towels—moisture is the enemy of a good sear.

Step 2: Boil the Pasta (The Right Way)

What to do: Bring a large pot of water to a rolling boil. Salt it heavily (think ocean water). Drop in your fettuccine and stir in the first minute so it doesn’t stick. Cook until al dente—firm with a bite.
Why it matters: Overcooked pasta turns mushy in the sauce. You want a little backbone because it’ll cook a bit more when combined later.

Chef Tip: Scoop out a mug of that starchy pasta water before draining. That stuff helps your sauce cling to the noodles like it was meant to be there.

Step 3: Sauté the Veggies (Build Your Flavor Base)

What to do: Melt 1 tbsp of butter in a large skillet over medium-high heat. Add the sliced peppers and cook for about 5 minutes, until they start to soften and blister. Stir in the garlic and sauté for 30 seconds.
Why it matters: The peppers add crunch and color, and that garlic? It’s your flavor backbone. But garlic burns fast—so timing is everything.

Frank-style Note: Burned garlic is the saddest thing in the kitchen. Bitter, acrid, and ruins everything. Don’t walk away here.

Step 4: Sear the Shrimp (And Don’t Rush It)

What to do: Push the peppers to the side of the skillet. Add the other tablespoon of butter, then place your shrimp in a single layer. Season them with Cajun spice in the pan, not before. Sear for 2 minutes per side until pink and slightly golden.
Why it matters: Shrimp cook fast—overdo it and they go from juicy to chewy. Seasoning in the pan reduces moisture and helps the spice stay punchy, not soggy.

Chef Commandment: Don’t crowd the pan. If you can’t see the skillet bottom between shrimp, you’re steaming, not searing.

Step 5: Build the Sauce and Marry It All Together

What to do: Lower heat to medium-low. Pour in the cream, stir gently, and add the Parmesan. Let it simmer 2–3 minutes until the sauce thickens just enough to coat the back of a spoon. Add a splash of pasta water if it feels too thick.
Once the sauce is smooth, toss in the cooked pasta and give everything a good stir. Kill the heat and let the pasta sit in the sauce for 3–5 minutes before serving.
Why it matters: This final step lets the starch from the pasta thicken the sauce naturally and brings all the flavors together. Resting time allows the pasta to soak in the sauce, not just sit on top of it.

Frank’s Final Move: Hit it with a squeeze of lemon juice and a shower of fresh parsley right before serving. Brightens everything up.

Cooking Tips & Techniques

Pat shrimp dry: Wet shrimp don’t sear—they sulk.
Season in layers: Shrimp, veggies, sauce—everything gets a hit.
Let it rest: Pasta resting in sauce = flavor explosion.
Add pasta water slowly: Just enough to get a creamy, clingy sauce.

Customization Ideas

Protein swap: Chicken, sausage, or tofu all play nice.
Veg it up: Spinach, mushrooms, cherry tomatoes, broccoli—you name it.
Spice boost: Add cayenne, hot sauce, or smoked paprika to the Cajun mix.

Storage & Reheating Instructions

Fridge: Store airtight for up to 3 days.
Reheat: Low and slow on the stovetop with a splash of cream or broth to bring it back to life.

Avoid the microwave if you can. It kills the texture. Skillet is best.

Chef’s Helpful Tips

Fresh lemon juice > bottled. Every time.
Parmesan melts better when finely grated.
Use your senses. Sauce should coat the back of a spoon. Shrimp should be firm and opaque, not rubbery.

I once told a buddy, “You’ll know the sauce is ready when it hugs the spoon like it misses it.” He laughed. Then he tasted it. He stopped laughing.
