Creamy Spinach Mushroom Shrimp Shells is the ultimate cozy comfort meal for seafood lovers with the decadent creaminess you crave tucked into every bite of perfectly tender pasta. It is a crowd pleaser on family nights or when you want something just a little bit fancy without too much fuss.

I first whipped this up when I had leftover shrimp from a holiday party and some wilting spinach in the fridge. It was an instant hit and my family now cheers whenever I say it is on the menu.

Ingredients

  • Jumbo pasta shells: They make the perfect vessel for the creamy filling Choose shells that are intact with no cracks
  • Olive oil: This delivers richness and helps sauté the veggies Use a good extra virgin one for the best flavor
  • White or cremini mushrooms: Mushrooms add earthiness and texture Pick firm dry mushrooms for best results and clean with a damp cloth
  • Garlic: Adds aromatic depth Fresh garlic cloves really shine here
  • Onion: Provides sweetness and a mellow background Use a small yellow or white onion
  • Shrimp: Brings sweet briny flavor and tender protein Go for raw peeled and deveined shrimp for easiest prep
  • Fresh spinach: Bright color and gentle earthiness Baby spinach leaves are easiest to chop and cook down quickly
  • Cream cheese: Creates the base of the creamy filling Let it sit at room temp so it blends easily
  • Heavy cream: Lightens the filling and brings luscious texture
  • Parmesan cheese: Adds sharp savory notes and helps the tops crisp up Freshly grated melts best
  • Salt and black pepper: Essential for seasoning
  • Fresh parsley: Brings a pop of freshness at the end and looks beautiful

I have always loved how Parmesan cheese forms that crispy top in the oven My son once declared it the best part and now he sneaks into the kitchen to grab the crispiest shell before anyone else can

Storage Tips

Store leftovers in an airtight container in the fridge for up to three days To reheat add a splash of milk to keep everything creamy and zap in the microwave or warm in a low oven covered so it does not dry out

Ingredient Substitutions

If you do not have shrimp swap in diced cooked chicken or even flaked canned tuna If mushrooms are not your thing try finely chopped zucchini or bell peppers Ricotta can stand in for cream cheese if that is what you have

Serving Suggestions

Serve these shells with garlic bread or a crisp green salad A sprinkling of lemon zest right before serving wakes the flavors up even more For a holiday meal pair with roasted asparagus

Common Queries

→ Can I use frozen shrimp instead of fresh?

Yes, thaw frozen shrimp thoroughly, then pat dry before cooking to prevent excess water in the filling.

→ Which type of mushrooms work best?

White or cremini mushrooms both provide a mild, earthy flavor that complements shrimp and spinach well.

→ Is there a substitute for cream cheese?

You can use ricotta or mascarpone cheese for a similarly creamy texture in the filling.

→ How do I prevent pasta shells from tearing?

Cook shells just until al dente and handle gently. Drizzle with a little oil to keep from sticking while filling.

→ Can I prepare the dish ahead of time?

Yes, assemble filled shells in the baking dish, refrigerate covered, and bake just before serving for best results.

Steps to Follow

Step 01

Bring a large pot of salted water to a boil. Add the jumbo shells and cook until al dente, about 10–12 minutes. Drain and set aside, keeping them warm.

Step 02

Heat the olive oil in a large skillet over medium heat. Add the chopped onion and cook until softened, about 3–4 minutes. Stir in the mushrooms and cook another 4–5 minutes, until they release their juices and begin to brown. Add the garlic and cook 30 seconds until fragrant.

Step 03

Push the veggies to one side of the pan. Add the chopped shrimp to the empty side, season with a pinch of salt and pepper, and cook 2–3 minutes until just pink and opaque. Stir together with the veggies.

Step 04

Reduce heat to low. Stir in the cream cheese until melted and smooth. Pour in the heavy cream and whisk until combined. Add ¼ cup of Parmesan and stir until melted into the sauce.

Step 05

Stir in the chopped spinach and cook 1–2 minutes until wilted. Taste and adjust seasoning with salt and pepper.

Step 06

Spoon the shrimp-spinach mixture into each pasta shell, arranging them in a single layer in a baking dish (about 9×13 inches).

Step 07

Sprinkle the remaining ¼ cup Parmesan over the filled shells. Place under a preheated broiler for 2–3 minutes, or bake at 375°F for 8–10 minutes, until the tops are lightly golden and bubbly.
