What Makes This Recipe Different

Most creamy Cajun shrimp pasta recipes use heavy cream and broth - and that's it.

Here's what elevates this version:

1. Homemade Cajun seasoning (so you control the salt + heat)

2. Properly seared shrimp (no rubbery overcooked seafood)

3. Bone broth collagen instead of regular broth

4. Pasta water emulsification for that glossy restaurant sauce

We're not just making pasta. We're building layers.

here's what you need

For the Shrimp

• 1 lb large shrimp, peeled & deveined

• 1 tablespoon olive oil

Homemade Cajun Seasoning

• 1 teaspoon smoked paprika

• ½ teaspoon garlic powder

• ½ teaspoon onion powder

• ½ teaspoon dried thyme

• ½ teaspoon dried oregano

• ¼-½ teaspoon cayenne pepper

• ½ teaspoon salt

• ¼ teaspoon black pepper

Pasta

• 12 oz fettuccine or linguine

• Salted pasta water (reserve 1 cup)

Creamy Bone Broth Sauce

• 2 tablespoon butter

• 3 cloves garlic, minced

• ½ small shallot or onion, diced

• 1 cup heavy cream

• ½ cup freshly grated Parmesan

How to Make Creamy Cajun Shrimp Pasta

Step 1: Cook the Pasta

Boil pasta in well-salted water until just al dente. Reserve 1 cup of pasta water before draining.

Step 2: Season the Shrimp

Toss shrimp with olive oil and all Cajun seasoning.

Step 3: Sear

Heat a large skillet over medium-high heat. Sear shrimp 1-2 minutes per side until just cooked. Remove and set aside.

Tip: Do not overcrowd the pan. Shrimp should sear, not steam.

Step 4: Build the Sauce

Reduce heat to medium. Add butter and sauté shallots until softened. Add garlic and cook 30 seconds.

Whisk 1 scoop bone broth collagen with ½ cup hot water until dissolved. Pour into skillet and simmer for 1 minute.

Add heavy cream and Parmesan. Stir until smooth and slightly thickened.

Step 5: Emulsify

Add pasta directly to the sauce. Slowly add reserved pasta water (¼ cup at a time) until glossy and creamy.

This is what makes the sauce cling to the noodles.

Step 6: Finish

Return shrimp to the pan. Toss gently. Add lemon juice at the end to brighten the richness.

Garnish and serve immediately.

What Does Bone Broth Collagen Do in This Recipe?

Instead of traditional boxed broth, we're using Vitauthority bone broth collagen.

Why?

• Adds protein

• Adds savory depth

• Blends seamlessly into hot liquids

• Doesn't thin the sauce

• Keeps flavor clean

It's a simple swap that makes this creamy pasta feel a little more balanced.

Tips for Perfect Cajun Shrimp Pasta

• Use freshly grated Parmesan (pre-shredded won't melt properly).

• Add lemon juice at the end - never before cream thickens.

• If sauce gets too thick, add more pasta water, not cream.

• Taste and adjust salt last - Cajun seasoning brands vary.

How to Adjust the Heat

Mild: Skip cayenne.
Medium: ¼ teaspoon cayenne.
Spicy: ½ teaspoon cayenne + crushed red pepper on top.

Cooking for kids?

Make the sauce mild and add heat to individual plates.

Can I Make This Ahead?

You can prep:

But for best texture, this pasta is best served fresh.

What to Serve With Cajun Shrimp Pasta

• Simple arugula salad with lemon vinaigrette

• Roasted asparagus

• Charred broccoli

Keep sides light - the pasta carries the richness.

Frequently Asked Questions

Can I use frozen shrimp?

• Yes. Just thaw fully and pat dry before seasoning.

Can I use half and half instead of heavy cream?

• Yes, but sauce will be slightly thinner. Use less pasta water.

Can I substitute chicken?

• Absolutely. Thin-sliced chicken breast or thighs work beautifully.

Can I make this gluten-free?

• Yes. Use gluten-free pasta and confirm seasoning is GF.
