Spinach and ricotta stuffed shells are one of those comfort food classics that never go out of style creamy cheesy filling packed into tender pasta shells and nestled in tangy marinara sauce With every bite you get satisfying richness and the pop of spinach to keep it light This is my favorite way to feed a crowd or make a cozy weeknight dinner feel extra special
I remember making these shells for a friend's birthday potluck Everyone went back for seconds and it turned a simple dinner into a memory we still laugh about
Ingredients
- Jumbo pasta shells: These create the perfect pockets for stuffing Look for shells with no cracks
- Ricotta cheese: Creamy and mild Full fat gives the best texture
- Shredded mozzarella cheese: Melts beautifully and helps bind the filling Choose whole milk mozzarella for better melt
- Grated Parmesan cheese: Adds salty depth Use real Parmigiano Reggiano if you can
- Large egg: Helps keep the filling together A fresh egg will give you the creamiest texture
- Fresh spinach or frozen: Fresh gives a mild green flavor and good texture Frozen is convenient and budget friendly Just squeeze out all the moisture
- Garlic: Brings aroma and a little punch Use fresh cloves for the brightest flavor
- Marinara sauce: Tangy and balanced Go for a brand with few added sugars or make your own
- Olive oil: Adds richness Use extra virgin for the most flavor
- Italian seasoning: Rounds out the filling Choose a blend with oregano basil and thyme
- Salt and freshly ground black pepper: Season to taste Always taste your filling before stuffing
- Fresh basil leaves for garnish: Adds color and fresh herby aroma Totally optional but I love the finish
Instructions
- Prepare the Pasta Shells:
- Boil a large pot of salted water and add the shells Cook them until al dente which means tender but with a little bite usually about eight to ten minutes Stir gently so they do not break Drain the shells and lay them out on a clean towel or tray to cool slightly This keeps them from sticking and tearing
- Make the Ricotta Filling:
- In a large bowl stir together the ricotta half the mozzarella Parmesan and the egg until completely smooth Make sure there are no streaks or clumps In a skillet warm the olive oil over medium heat Add the garlic and cook just until it smells fragrant about thirty seconds Do not let it brown Add chopped fresh spinach and cook until wilted about two to three minutes If you use frozen spinach get every bit of water out so the filling stays thick Let the spinach cool slightly then mix it into the cheese filling Season with Italian seasoning salt and plenty of pepper Taste the filling to check if it needs more salt
- Stuff the Shells:
- Heat your oven to three hundred seventy five degrees Fahrenheit Pour about one cup of marinara sauce over the bottom of a nine by thirteen inch baking dish Take each cooled shell and gently stuff with a couple tablespoons of filling You want enough to fill without splitting the shell Place the stuffed shells open side up on top of the sauce in a single layer Pour the rest of the marinara over the stuffed shells and sprinkle with the remaining mozzarella
- Bake to Perfection:
- Cover the pan with aluminum foil and bake for twenty minutes This allows everything to steam and meld Uncover and bake ten more minutes so the cheese can bubble and brown Check in the last few minutes so it does not overcook
- Serve and Enjoy:
- Let the shells rest for a few minutes so the flavors settle Garnish with torn fresh basil for a pretty finish Serve hot with garlic bread or a green salad Leftovers make the best lunch the next day

One of my favorite parts of this dish is sneaking bites of the ricotta filling before it goes into the pasta My daughter and I always share a little spoonful as we cook and it has become our kitchen tradition
Storage Tips
Leftover shells keep in the fridge for up to four days Store in an airtight container To reheat cover with foil and warm in the oven at three hundred fifty degrees or microwave in one minute bursts If you want to freeze assemble the shells but do not bake Wrap tightly in foil and freeze for up to two months Thaw in the fridge then bake as usual
