What Makes This Special

• Balanced creaminess: A touch of cream blended with Greek yogurt delivers a silky sauce that’s lighter than traditional Alfredo-style versions.
• Weeknight easy: Everything cooks in about 30 minutes with basic pantry spices and one skillet.
• Customizable heat: Adjust the Cajun seasoning and crushed red pepper to match your spice comfort zone.
• Meal-prep friendly: Reheats well with a splash of broth or milk, so leftovers don’t dry out.

Ingredients

• 8 ounces protein pasta (chickpea, lentil, or high-protein wheat penne or rotini)
• 1 pound large shrimp, peeled and deveined (tails on or off)
• 1 tablespoon olive oil
• 1 tablespoon unsalted butter
• 1 medium yellow onion, finely diced
• 3 garlic cloves, minced
• 1 red bell pepper, thinly sliced
• 1/2 cup low-sodium chicken or seafood broth
• 1/2 cup half-and-half or light cream
• 1/3 cup plain Greek yogurt (2% or 5%)
• 1/3 cup freshly grated Parmesan (plus more for serving)
• 2 to 2 1/2 teaspoons Cajun seasoning (store-bought or homemade), divided
• 1/4 teaspoon smoked paprika (optional for extra depth)
• 1/8 to 1/4 teaspoon crushed red pepper flakes (optional, for extra heat)
• Salt and black pepper to taste
• Juice of 1/2 lemon (plus wedges for serving)
• 2 tablespoons chopped parsley or scallions, for garnish

Instructions

1. Cook the pasta: Bring a large pot of salted water to a boil. Cook protein pasta according to package directions until just al dente. Reserve 1/2 cup of pasta water, then drain.
2. Season the shrimp: Pat shrimp dry.

   Toss with 1 teaspoon Cajun seasoning, a pinch of salt, and black pepper.

3. Sear the shrimp: Heat olive oil and butter in a large skillet over medium-high. Add shrimp in a single layer and cook 1–2 minutes per side until pink and just opaque. Transfer to a plate.
4. Sauté aromatics: Lower heat to medium.

   Add onion and red bell pepper; cook 4–5 minutes until softened. Stir in garlic; cook 30 seconds until fragrant.

5. Build the sauce base: Sprinkle in remaining Cajun seasoning, smoked paprika, and red pepper flakes if using. Stir for 10–15 seconds.

   Pour in broth, scraping up any browned bits. Simmer 2 minutes to reduce slightly.

6. Add cream and cheese: Stir in half-and-half and bring to a gentle simmer. Reduce heat to low and add Parmesan, stirring until melted and smooth.
7. Temper the yogurt: In a small bowl, whisk Greek yogurt with 2 tablespoons of warm sauce to prevent curdling.

   Stir the tempered yogurt into the skillet. Keep heat low; do not boil.

8. Combine pasta and shrimp: Add cooked pasta and shrimp to the sauce. Toss gently until coated.

   If the sauce is too thick, add splashes of reserved pasta water to loosen.

9. Finish and season: Add lemon juice. Taste and adjust salt, pepper, and Cajun seasoning. The sauce should be creamy, slightly tangy, and warmly spiced.
10. Serve: Top with parsley or scallions and extra Parmesan.

    Serve hot with lemon wedges.

Storage Instructions

• Refrigerator: Cool completely, then store in an airtight container for up to 3 days.
• Freezer: Not ideal due to dairy and shrimp texture changes. If you must, freeze up to 1 month and reheat gently.
• Reheating: Warm on low in a skillet with a splash of broth or milk, stirring until creamy again. Microwave in short bursts, stirring between intervals.

  Avoid boiling to prevent the sauce from breaking and the shrimp from overcooking.

Why This is Good for You

• Protein-packed: Shrimp and protein pasta deliver a solid protein boost that supports muscle repair and keeps you full longer.
• Lighter cream profile: Combining a small amount of cream with Greek yogurt creates a satisfying texture with fewer calories than heavy cream alone.
• Fiber and micronutrients: Chickpea or lentil pasta adds fiber and minerals, while bell peppers and onion bring vitamin C and antioxidants.
• Smarter sodium: Using low-sodium broth and seasoning to taste keeps salt in check without sacrificing flavor.

Pitfalls to Watch Out For

• Overcooking shrimp: They turn rubbery fast. Pull them as soon as they are pink and just opaque.
• Boiling after adding yogurt: High heat can cause the sauce to split. Keep it at a gentle simmer or lower.
• Heavy hand with Cajun seasoning: Many blends include salt.

  Taste as you go to avoid oversalting.

• Skipping pasta water: A few splashes help you dial in a silky, clingy sauce instead of a thick, gloppy one.
• Using pre-shredded cheese: It often contains anti-caking agents that resist melting. Freshly grated Parmesan melts smoother.

Alternatives

• Protein swaps: Use chicken breast, turkey sausage, or firm tofu. For tofu, press well and pan-sear until golden before adding to the sauce.
• Dairy-free version: Replace cream with unsweetened cashew cream or coconut milk (light), and use a dairy-free Parmesan-style cheese or nutritional yeast.
• Veggie boost: Add spinach, zucchini ribbons, or mushrooms during the sauté step.

  Wilt spinach at the end to keep it vibrant.

• Gluten-free: Choose a certified gluten-free protein pasta and ensure your Cajun seasoning is gluten-free.
• Milder or hotter: For less heat, reduce Cajun seasoning and skip red pepper flakes. For more kick, add cayenne or a few dashes of hot sauce.
• No yogurt on hand: Use extra cream and a squeeze of lemon for brightness, or blend cottage cheese until smooth and stir in off the heat.

FAQ

Can I make this ahead?

Yes. Cook the pasta slightly under al dente and keep shrimp just shy of fully cooked.

Combine everything, cool, and refrigerate. Reheat gently with a splash of broth until warmed through; the shrimp will finish cooking without getting tough.

What protein pasta works best?

Chickpea and lentil pastas hold up well and bring extra fiber. High-protein wheat blends also work and have a more traditional texture.

Choose short shapes like penne or rotini to catch the sauce.

How do I prevent the sauce from curdling?

Temper the Greek yogurt with warm sauce before adding, and keep the heat low once dairy is in the pan. Avoid rapid boiling after the yogurt and cheese go in.

Is frozen shrimp okay?

Absolutely. Thaw in the fridge overnight or in a sealed bag under cold running water for 10–15 minutes.

Pat very dry before seasoning and searing to get a good crust.

Can I make it without Parmesan?

Yes. The sauce will be slightly less savory. Add a teaspoon of Dijon mustard or an extra squeeze of lemon to brighten, or a spoonful of nutritional yeast for a cheesy note.

How spicy is this?

It’s moderately spicy with the base amount of Cajun seasoning.

If you’re heat-sensitive, start with 1 teaspoon and skip red pepper flakes, then add more to taste at the end.

What if the sauce gets too thick?

Stir in warm pasta water or broth a little at a time until it loosens. Keep heat low and mix gently to maintain a smooth texture.

Can I use regular pasta?

Yes. It won’t be quite as protein-rich, but the flavor remains excellent.

Consider adding extra shrimp or a side of grilled chicken for more protein.
