My Family’s Low-Carb Shift & This Creamy Cajun Shrimp Pasta
The Recipe That Won Over Our Pasta Nights
I’ll never forget the night I tested this creamy Cajun shrimp pasta recipe for the first time. Chloe was at the kitchen table coloring, and my mom, Linda, leaned in to watch me swirl the shrimp through a bubbling skillet of creamy sauce. “It smells like our old fettuccine nights,” she said, smiling—but this time, the noodles were low-carb, the cream was light, and our stomachs didn’t feel heavy afterward.
We’d been working to shift our family meals toward lower-carb options—not to follow trends, but to feel more energized and balanced. I wanted meals that kept up with our pace without that post-dinner slump. So, pasta night had to evolve.
Why This Cajun Pasta Feels So Comforting—Yet Light
Cajun seasoning brings bold flavor with smoky paprika, garlic, and cayenne—perfectly complementing tender shrimp and a creamy sauce. For the ideal creamy Cajun shrimp pasta, the secret lies in creating richness without heavy dairy or flour-based thickeners.
Here’s what worked for us:
- A mix of heavy cream and cream cheese for a full-bodied texture that’s still low in carbs.
- A splash of chicken broth to thin it slightly and carry flavor.
- Shrimp seared with Cajun spice for flavor that doesn’t rely on sugar or added carbs.
If you enjoy building low-carb comfort meals from scratch, you might also love these low carb bagels—they use almond flour and cream cheese in a way that feels rich and satisfying without the carb load.

How to Make Creamy Cajun Shrimp Pasta Low-Carb & Luscious
Ingredients That Create Creaminess Without the Carbs
To make this creamy Cajun shrimp pasta both low in carbs and rich in comfort, the key is in using smart fats, bold seasonings, and pasta alternatives that don’t weigh you down. Below is the exact ingredient breakdown I use for a satisfying, weeknight-friendly dinner that doesn’t spike blood sugar or leave you sluggish.
| Ingredient | Purpose |
|---|---|
| 1 lb large shrimp (peeled and deveined) | Protein base; sweet and tender contrast to spice |
| 1 tbsp olive oil | For sautéing shrimp and enhancing flavor |
| 2 tbsp Cajun seasoning | Smoky heat and bold flavor |
| 2 garlic cloves (minced) | Adds depth to the creamy sauce |
| 1 cup heavy cream | Main creamy base with low carbs |
| 2 tbsp cream cheese | Thickens and smooths the sauce |
| 1/2 cup grated Parmesan cheese | Adds saltiness, umami, and helps thicken naturally |
| 1/4 cup chicken broth (optional) | Loosens sauce if it gets too thick |
| 8 oz low-carb noodles (hearts of palm, zoodles, or penne pasta) | Low-carb pasta base to absorb all the creamy flavor |
| Salt & black pepper to taste | Final balance and seasoning |
Tip: You can also use Stevia – a natural sweetener with zero carbs.
Choosing the Right Low-Carb Pasta
This creamy sauce deserves a pasta that pairs well and keeps your plate light. These three work beautifully:
- Hearts of Palm Pasta – Mild flavor and pasta-like texture. Great for soaking up sauces.
- Zucchini Noodles (Zoodles) – Fresh and clean, but should be added last to avoid excess moisture.
- Shirataki Noodles – Ultra low-carb and gluten-free, but rinse thoroughly to remove odor.
What cream do you use for shrimp pasta?
For the richest result with the fewest carbs, go with heavy cream and balance it with a touch of cream cheese. You’ll get thickness and flavor without flour or cornstarch.
Tip: You can also use Stevia – a natural sweetener with zero carbs.
We recommend this Pure Organic Stevia Powder (8 oz)—made from high-grade green leaf extract Reb-A with a reduced bitter aftertaste. It’s keto-friendly, 0-calorie, and ideal as a sugar alternative in creamy sauces or low-carb recipes.
Cooking Creamy Cajun Shrimp Pasta to Perfection
Step-by-Step Cooking Method for Shrimp and Sauce
Making this creamy Cajun shrimp pasta is all about timing and heat control. Here’s exactly how I do it on a weeknight without missing a beat:
Step 1: Season and sear the shrimp
Coat the peeled shrimp in olive oil and a generous sprinkle of Cajun seasoning. Heat a large skillet over medium-high and sauté the shrimp for about 2 minutes per side. They should be just pink and curled. Remove them from the pan and set aside.
Step 2: Build the sauce base
In the same skillet (don’t rinse it—those bits are flavor gold), add a little more oil if needed. Sauté garlic until fragrant, about 30 seconds. Pour in the heavy cream and stir gently.
Step 3: Thicken with cheese
Whisk in cream cheese and Parmesan until melted. Let the sauce simmer on low for about 3–5 minutes until it thickens slightly. If it feels too rich, add a splash of chicken broth.
Step 4: Add pasta and shrimp
Toss in your cooked low-carb noodles and stir to coat. Then return the shrimp to the pan and stir gently to combine. Let everything heat through for 1–2 more minutes.
Step 5: Taste and season
Before serving, taste the sauce. Add salt and pepper as needed—remember, Cajun blends often contain salt already, so taste first.
This whole process takes just about 20 minutes from pan to plate.
Balancing Cajun Heat for the Whole Family
To make creamy Cajun shrimp pasta family-friendly, start with 1 tablespoon of Cajun seasoning and adjust to taste. Use a mild blend or homemade mix if cooking for kids or spice-sensitive guests. More cream or cheese can soften the heat, and plain hearts of palm pasta works well for milder servings. For those who love extra spice, like Linda, just add a dash of cayenne separately.
What cream to use in seafood pasta?
Heavy cream is the best option for seafood pasta—it’s rich enough to hold the flavor of shrimp, doesn’t break when heated, and keeps your sauce smooth without needing thickeners.
Serving Creamy Cajun Shrimp Pasta & Keeping It Fresh
Plating Tips & What to Serve With It
This creamy Cajun shrimp pasta doesn’t need much to shine. The sauce is bold, the shrimp are tender, and the whole dish already feels like something special. That said, a few thoughtful plating ideas can really elevate the experience:
- Serve it hot on warm plates: This helps preserve the creamy texture and keeps everything luscious from the first bite to the last.
- Top with fresh herbs: A sprinkle of chopped parsley or green onions adds brightness and a touch of color.
- Add a lemon wedge on the side: Just a squeeze can cut through the richness and highlight the Cajun spice beautifully.
As for side dishes, we like to keep it clean and green. Think:
- Arugula or spinach salad with lemon vinaigrette
- Roasted asparagus or green beans with garlic
- Avocado slices sprinkled with a touch of sea salt for a boost of healthy fats
When we had Olivia and Sophie over for dinner last Friday, I served this dish with a quick baby kale salad tossed in olive oil and balsamic vinegar. Everyone went back for more, and the bread wasn’t missed at all.
How to Store Leftovers & Reheat Without Losing Flavor
Creamy sauces can be tricky the next day, but with a few adjustments, this dish stays delicious:
- Storage: Store any leftovers in an airtight container in the refrigerator. It stays fresh for up to 2 days.
- Reheating: Use a skillet over low heat. Pour in a bit of cream or broth and stir softly to thin the sauce without causing it to separate.
- Avoid microwaving at full power: Instead, warm it up at half power to reheat slowly and evenly.
If you’re prepping ahead, keep the pasta and shrimp stored separately from the sauce. Mix them together right before serving to ensure optimal texture and taste.
Chloe even took a small portion to school once in a thermos—it was still creamy and flavorful by lunch, and her note to me that day just said: “More pasta please!”
FAQ About Creamy Cajun Shrimp Pasta
What to add to pasta to make it more creamy?
To make pasta creamier without flour, stir in cream cheese, heavy cream, and Parmesan. These three thicken the sauce naturally and add a rich, smooth texture. A small splash of broth can help loosen it if needed.
What cream do you use for shrimp pasta?
Heavy cream is the best choice for shrimp pasta. It’s low in carbs, thick enough to hold flavor, and doesn’t curdle under heat. For even more richness, add a bit of cream cheese or a spoonful of mascarpone.
What are the three ingredients in creamy pasta?
The essential trio in creamy pasta includes:
Heavy cream or cream cheese (for the base)
Parmesan cheese (for flavor and thickness)
Seasoning (like garlic, salt, or Cajun spices for depth)
What cream to use in seafood pasta?
Always go for heavy cream when making seafood pasta. It holds up to heat and pairs well with the delicate flavor of shrimp or fish. Avoid milk or half-and-half—they tend to separate or become too watery.
