Ingredients Breakdown

This recipe serves 4 people generously.

Fats & Oils

• 2 tablespoons olive oil – For searing the salmon and sautéing garlic.

Seasonings & Aromatics

• 3 cloves garlic, minced – The foundation of the sauce’s aroma.
• ¼ teaspoon crushed red pepper flakes (optional) – For an extra layer of spice.
• Salt and black pepper – To taste.

Sauce Base

• 1 cup heavy cream – Gives the sauce its rich, silky texture.
• ½ cup chicken broth – Balances richness with savory depth.
• ½ cup freshly grated Parmesan cheese – Melts into the sauce for creamy, nutty flavor.
• 1 tablespoon fresh lemon juice – Brightens and balances the richness.
• 1 teaspoon lemon zest – Adds fresh citrus aroma.

Garnish

Tools & Equipment Needed

• Large pot for boiling pasta
• Large deep skillet or sauté pan (12-inch recommended)
• Cutting board & sharp knife
• Measuring cups & spoons
• Tongs or pasta fork for tossing pasta
• Microplane or fine grater for lemon zest and Parmesan

Step-by-Step Instructions

1. Cook the pasta

Bring a large pot of salted water to a boil. Add the 12 oz spaghetti and cook according to package directions until al dente. Reserve ½ cup pasta water before draining, then set the pasta aside.

2. Prepare the salmon

While the pasta cooks, pat the 1 lb salmon chunks dry with paper towels. Season with 1 tablespoon Cajun seasoning, plus a pinch of salt and pepper.

3. Sear the salmon

Heat 2 tablespoons olive oil in a large skillet over medium-high heat. Add the salmon pieces in a single layer, searing for 2–3 minutes per side until golden and almost cooked through. Remove salmon to a plate and set aside.

4. Sauté garlic and spices

In the same skillet, reduce heat to medium. Add the minced garlic and, if using, ¼ teaspoon crushed red pepper flakes. Sauté for 30 seconds until fragrant—be careful not to burn the garlic.

5. Build the creamy Cajun sauce

Pour in ½ cup chicken broth, scraping up any browned bits from the pan. Add 1 cup heavy cream, ½ cup Parmesan cheese, 1 tablespoon lemon juice, 1 teaspoon lemon zest, and another pinch of Cajun seasoning if you want more spice. Stir until smooth and slightly thickened, about 3–4 minutes.

6. Combine pasta and salmon

Add the cooked spaghetti to the skillet, tossing it in the sauce until coated. If the sauce is too thick, add a splash of the reserved pasta water to loosen it. Gently fold the salmon pieces back into the pasta, taking care not to break them apart too much.

7. Taste & adjust

Season with salt, pepper, and extra Cajun seasoning to your liking.

8. Serve & garnish

Transfer to plates or serve family-style from the skillet. Garnish with chopped parsley and an extra sprinkle of Parmesan if desired.

Tips & Variations

• Swap the pasta – Try linguine, fettuccine, or even penne for a twist.
• Make it lighter – Use half-and-half instead of heavy cream, though the sauce will be less rich.
• Go extra spicy – Add diced jalapeños or increase red pepper flakes.
• Seafood swap – Shrimp, scallops, or even crab meat work beautifully in place of salmon.
• Vegetable boost – Toss in baby spinach, cherry tomatoes, or roasted red peppers.

FAQs

Q1: Can I use frozen salmon?

You can easily reduce the Cajun seasoning and skip the red pepper flakes for a milder version.

Serving Suggestions

Serve this pasta in shallow bowls so the sauce pools at the bottom. Garnish with fresh parsley, extra Parmesan, and maybe a thin lemon slice for presentation. A sprinkle of extra Cajun seasoning on top adds color and a hint of spice.

Recipe Variations

• Cajun Shrimp Alfredo – Swap salmon for shrimp and skip the lemon for a more traditional Cajun cream pasta.
• Lemon Basil Salmon Pasta – Replace Cajun seasoning with fresh basil for a lighter, herb-forward dish.
• Creamy Tuscan Salmon Pasta – Add sun-dried tomatoes, spinach, and Italian herbs instead of Cajun spice.

Ingredient Spotlight: Cajun Seasoning

Cajun seasoning is a bold blend typically made from paprika, garlic powder, onion powder, oregano, thyme, cayenne pepper, and black pepper. It adds smoky heat and earthy flavor to dishes. When buying pre-made blends, check for salt levels—some are quite salty, so you may need to adjust other seasoning accordingly.

Pro Cooking Tips

• Don’t overcook the salmon—remove it from the pan just before it’s done so it stays moist when you add it back.
• Use freshly grated Parmesan—it melts better and has superior flavor.
• Reserve pasta water—it’s liquid gold for adjusting sauce consistency.

Storage & Freezing Guide

• Fridge: Store leftovers in an airtight container for up to 2 days.
• Freezer: Not recommended—cream sauces can separate, and salmon can become dry when thawed.
• Reheat: On the stovetop over low heat with a splash of broth or cream.
