Ingredients

Main Ingredients

12 oz medium pasta shells (conchiglie)

1 lb large shrimp, peeled and deveined

8 oz cremini or button mushrooms, sliced

3 cups fresh baby spinach

Cream Sauce Base

1½ cups heavy cream

½ cup chicken broth or seafood broth

¾ cup grated Parmesan cheese

4 cloves garlic, minced

2 tablespoons butter

1 tablespoon olive oil

Seasonings & Toppings

½ teaspoon paprika or smoked paprika

1 teaspoon Italian seasoning

Salt and freshly cracked black pepper, to taste

2 tablespoons sour cream or Greek yogurt, for serving

2 tablespoons fresh parsley, chopped

1–2 teaspoons fresh lemon juice, optional

Instructions

Cook the Pasta

Bring a large pot of salted water to a boil. Add the pasta shells and cook according to the package directions until al dente.

Before draining, reserve about ½ cup of pasta water. Drain the shells well and set them aside.

Avoid overcooking the pasta because it will be added back to the warm sauce later.

Season the Shrimp

Pat the shrimp dry with paper towels. Season both sides with paprika, a little salt, and freshly cracked black pepper.

Keeping the shrimp dry before cooking helps them sear rather than steam and allows the seasoning to adhere properly.

Sear the Shrimp

Heat the olive oil and 1 tablespoon of butter in a large skillet over medium-high heat.

Add the shrimp in a single layer and cook for approximately 1–2 minutes per side, or until they turn pink and opaque and develop lightly golden edges.

Remove the shrimp from the skillet and place them on a plate. Avoid overcooking because shrimp can become rubbery if left on the heat too long.

Cook the Mushrooms

Reduce the heat to medium and add the remaining tablespoon of butter to the same skillet.

Add the sliced mushrooms and cook for about 5–6 minutes. Stir occasionally and allow the mushrooms to release their moisture and develop golden-brown edges.

Add the Garlic and Spinach

Add the minced garlic and Italian seasoning to the mushrooms. Cook for about 30–60 seconds until fragrant.

Add the fresh spinach and stir gently. Cook for 1–2 minutes, just until the spinach wilts.

Make the Cream Sauce

Pour the chicken or seafood broth into the skillet and scrape the bottom with a wooden spoon to loosen the flavorful browned bits.

Allow the broth to simmer for about 1–2 minutes.

Reduce the heat to medium-low and pour in the heavy cream. Stir gently and let the sauce simmer for approximately 3–4 minutes. Do not allow it to boil aggressively.

Gradually stir in the grated Parmesan cheese until melted and the sauce becomes smooth and creamy.

Season with salt and black pepper to taste.

Combine the Pasta and Shrimp

Add the cooked pasta shells to the creamy mushroom and spinach sauce. Toss gently until the shells are evenly coated.

Return the cooked shrimp to the skillet and gently fold them into the pasta.

If the sauce is thicker than desired, add a splash of reserved pasta water and stir until smooth.

Finish and Serve

Turn off the heat and add a small squeeze of lemon juice if desired. The acidity helps brighten the creamy sauce and balances the richness.

Divide the pasta among serving bowls. Add a small dollop of sour cream or Greek yogurt to the center of each serving, then garnish with fresh parsley and extra Parmesan if desired.

Serve immediately while the sauce is warm and silky.

Tips

Use Large Shrimp

Large shrimp are ideal because they remain juicy and tender while providing a satisfying bite. Smaller shrimp can also be used, but reduce the cooking time accordingly.

Dry the Shrimp Before Searing

Patting shrimp dry removes excess surface moisture and helps them develop better color in the skillet.

Do Not Overcook the Shrimp

Shrimp cook quickly. Once they turn opaque and pink and curl gently into a loose C shape, they are generally ready. Remove them from the pan promptly.

Brown the Mushrooms

Give the mushrooms enough time to release their moisture before adding the cream. Properly browned mushrooms provide much deeper flavor.

Keep the Cream Sauce Gentle

Heavy cream and Parmesan are best cooked over medium-low heat. A vigorous boil can cause the sauce to become too thick or separate.

Add Parmesan Gradually

Stir the Parmesan into the warm cream gradually rather than dumping it in all at once. This helps it melt smoothly into the sauce.

Reserve Pasta Water

Starchy pasta water is an easy way to adjust the consistency. Add it one tablespoon or small splash at a time.

Serve Immediately

Cream sauces naturally thicken as they cool. Serve the pasta while hot for the smoothest consistency.

Variations

Make It Spicy

Add ¼–½ teaspoon crushed red pepper flakes to the sauce or season the shrimp with cayenne for a spicy kick.

Use Seafood Broth

Seafood broth adds extra depth and complements the shrimp beautifully. Chicken broth provides a milder, more neutral base.

Add Sun-Dried Tomatoes

Chopped sun-dried tomatoes can be added with the mushrooms for a sweet, tangy flavor that works especially well with spinach and Parmesan.

Try Different Pasta

Fettuccine, penne, rigatoni, bow ties, or spaghetti can replace the shells. Choose pasta with curves or ridges to hold onto the creamy sauce.

Make It Extra Cheesy

Add a little shredded mozzarella or extra Parmesan for a richer, cheesier sauce.

Add More Vegetables

Broccoli, asparagus, zucchini, roasted red peppers, or cherry tomatoes can be added for additional color and texture.

Use Chicken Instead of Shrimp

For a different protein, replace shrimp with thinly sliced chicken breast. Cook the chicken completely before preparing the sauce.

Lighten the Sauce

Use half-and-half instead of heavy cream and Greek yogurt instead of sour cream for serving. The sauce will be lighter while still creamy.

Q&A

Can I use frozen shrimp?

Yes. Thaw the shrimp completely and pat them very dry before seasoning and cooking.

Can I use frozen spinach?

Yes. Thaw and squeeze out as much excess water as possible before adding it to the skillet.

What type of pasta works best?

Medium shells are excellent because their shape catches the creamy sauce, mushrooms, spinach, and small pieces of shrimp. Penne, rigatoni, and fettuccine are also good alternatives.

Can I make this recipe without sour cream or Greek yogurt?

Yes. The topping is optional. The pasta is already creamy from the heavy cream and Parmesan.

Can I use milk instead of heavy cream?

You can, but the sauce will be thinner and less rich. For a closer substitute, use half-and-half.

How do I prevent the shrimp from becoming rubbery?

Cook shrimp only until they are opaque and pink, then remove them from the skillet. Add them back near the end rather than simmering them in the sauce for a long time.

How should I store leftovers?

Transfer leftovers to an airtight container and refrigerate for up to 3 days.

How do I reheat creamy shrimp pasta?

Reheat gently over low heat or in short microwave intervals. Add a small splash of broth, milk, or water to loosen the sauce as needed.
