Creamy Spinach Mushroom Shrimp Shells is truly a weeknight miracle dish that feels like a restaurant treat yet comes together quickly in one skillet The combination of sweet juicy shrimp with earthy mushrooms bright spinach and a silky cheesy sauce hugs each bite of shell pasta so you get a little bit of everything in every forkful I first whipped this up for my partner when we needed a comfort meal after a long cold day and now it is our go to for both easy dinners and special nights in
The first time I made this it felt so fancy yet fast my husband said it tasted like something you would order at a bistro My favorite part is how the sauce clings to every shell for maximum flavor in every bite
Ingredients
- Shell pasta: Choose a sturdy shape with pockets to hold the sauce I love using medium shells for this
- Large shrimp: Look for wild caught ones if possible for the freshest flavor and firm texture
- Olive oil: Adds flavor and helps sear the shrimp
- Butter: Creates a rich flavor base for the sauce
- Garlic: Freshly minced gives the sauce savory depth and aroma
- Mushrooms: Choose white or cremini for classic flavor slice evenly so they cook uniformly
- Baby spinach: Adds color nutrition and a subtle earthiness make sure leaves are fresh and vibrant
- Heavy cream: The key to that ultra creamy sauce select a good quality cream for best texture
- Chicken broth: Balances the richness and loosens the sauce homemade or low sodium is best
- Grated Parmesan cheese: Buy a wedge and grate it yourself for the most flavor and best melting
- Lemon juice: Adds brightness and a fresh finish use freshly squeezed if you can
- Chopped parsley: Optional but adds a pop of color and freshness
Step by Step Instructions
- Cook the Pasta:
- Boil the shell pasta in well salted water until just al dente Drain and set aside This timing is important so your pasta stays tender but not mushy
- Sear the Shrimp:
- Pat the shrimp dry then season all over with salt and pepper Heat olive oil in a large skillet over medium high Once shimmering add the shrimp in a single layer Cook for two to three minutes per side until they turn pink and opaque Remove shrimp to a plate so they do not overcook
- Sauté the Mushrooms and Garlic:
- Drop the heat to medium and add butter to the same skillet When melted add in minced garlic and all the sliced mushrooms Stir frequently and let the mushrooms sauté undisturbed for the first two minutes to get some browning This step draws out their earthy flavor Continue for another minute or two until mushrooms are caramelized and garlic is fragrant
- Wilt the Spinach:
- Add baby spinach by the handful into the mushrooms Stir gently as the leaves wilt down from the heat Aim for tender spinach that still has some color
- Make the Cream Sauce:
- Pour in the heavy cream and chicken broth stirring up any bits stuck to the pan Simmer for about four to five minutes The sauce should thicken slightly so it coats a spoon
- Finish the Sauce With Cheese:
- Sprinkle in freshly grated Parmesan Stir until melted and smooth This cheeses the sauce while adding nutty complexity
- Combine Everything:
- Add the cooked pasta and shrimp back into the pan Toss gently making sure every shell and piece is coated You can adjust seasoning to taste here too
- Final Touch:
- Squeeze half a lemon over the pan for brightness if desired Sprinkle with chopped parsley before serving for a restaurantworthy finish

I am a sucker for wild caught shrimp because their sweetness really pops in this dish Once I used garden fresh spinach picked that afternoon and my family raved that it was the best batch ever I make sure to save the first creamy taste for my youngest who always asks for more
Storage Tips
Leftovers keep well in a tightly covered container in the refrigerator for up to three days For best results reheat gently on the stovetop with a splash of broth or cream to restore the sauce Avoid microwaving the shrimp for too long because it can make them rubbery
Ingredient Substitutions
If you do not have shell pasta try penne farfalle or orecchiette which also hold sauce well For a dairy free version swap in full fat coconut milk and leave out the Parmesan trading for nutritional yeast For mushrooms any fresh variety works and if spinach is not on hand baby kale or Swiss chard tastes great too
Serving Suggestions
Serve this straight from the skillet family style with a green salad and crusty bread on the side Leftovers are delicious reheated for lunch Sometimes I like to add extra lemon zest or a sprinkle of red pepper flakes for a little zing
Cultural and Historical Context
