Equipements Needed
- Large Pot: For boiling the pasta shells.
- Mixing Bowls: One large one for the filling, a smaller one for seasoning.
- 9×13-inch Baking Dish: The perfect vessel for assembling and baking.
- Box Grater: If you’re grating your own cheese.
- Spoon or Cookie Scoop: Makes filling those shells a total breeze.
Ingredients
- 1 (12-oz) box jumbo pasta shells: The sturdy vessel for all that goodness.
- 2 cups whole milk ricotta cheese: For the creamiest, dreamiest base.
- 1 (10-oz) package frozen chopped spinach, thawed and squeezed very dry: Crucial for that vibrant green color and flavor without wateriness.
- 1 large egg: Helps bind the filling so it doesn’t spill out.
- 2 cups shredded mozzarella cheese, divided: For that iconic, irresistible stretch.
- 1/2 cup grated Parmesan cheese: Adds a sharp, salty, nutty depth.
- 2 cloves garlic, minced: For a essential aromatic punch.
- 1 tsp Italian seasoning: The classic flavor blend we all love.
- 1/2 tsp kosher salt, plus more for pasta water: To season the filling perfectly.
- 1/4 tsp black pepper: A little kick to balance the richness.
- 1 (24-oz) jar of your favorite marinara sauce: The speedy, saucy base of the dish.
- Fresh basil or parsley, for garnish: For a bright, fresh finish.
Step By Step
- Prep: Preheat your oven to 375°F. Grab your 9×13-inch baking dish and spread about 3/4 cup of the marinara sauce evenly over the bottom. This creates a saucy bed that prevents sticking.
- Cook the Shells: Bring a large pot of generously salted water to a boil. Cook the jumbo shells according to package directions for al dente—they’ll continue to cook in the oven. Drain them and rinse with cool water to stop the cooking and make them easier to handle.
- Make the Filling: In a large bowl, combine the ricotta, squeezed-dry spinach, egg, 1 cup of the mozzarella, Parmesan, garlic, Italian seasoning, salt, and pepper. Mix it all together until it’s fully combined.
- Stuff ‘Em: Now for the fun part! Take a cooked shell in your hand and spoon a heaping tablespoon of the filling into it. Gently place it seam-side up in the prepared baking dish. Repeat until all the shells are filled and snuggled tightly in the dish.
- Assemble & Bake: Pour the remaining marinara sauce over the top of the stuffed shells, then sprinkle the remaining 1 cup of mozzarella cheese over everything. Cover the dish tightly with foil and bake for 25 minutes. Then, remove the foil and bake for another 10-15 minutes, until the cheese is golden and the sauce is bubbly.
- Rest and Serve: Let the baked shells sit for about 5-10 minutes before serving. This helps everything set up so they don’t fall apart when you scoop them out. Garnish with fresh herbs and dig in!
Oven Temperatures
This recipe is designed for a conventional oven at 375°F. That’s the sweet spot for heating the filling all the way through while getting the cheese beautifully melted and slightly golden on top. If you’re using a convection oven, you can reduce the temperature by 25 degrees to 350°F and keep a close eye on it, as it may bake a few minutes faster.
Variations & Substitutions
- Dairy-Free/Vegan: Use your favorite plant-based ricotta and shreds. A flax egg (1 tbsp ground flax + 3 tbsp water) works great as a binder.
- Add Protein: Stir in a cup of shredded cooked chicken or smoked turkey into the filling for a non-vegetarian twist.
- Different Greens: Not a spinach fan? Try using an equal amount of thawed, squeezed frozen kale or chopped sautéed mushrooms.
- Extra Herby: Fold 2 tablespoons of freshly chopped basil or parsley right into the filling mixture for an extra fresh flavor.
- Spice It Up: Add a pinch of red pepper flakes to the filling for a littleThese shells are a whole meal on their own, but a simple side can round it out perfectly. A crisp, green salad with a tangy vinaigrette is my absolute go-to—it cuts through the richness of the pasta. A side of garlic bread is never a wrong answer for soaking up that extra sauce. And for a lighter option, some simple roasted broccoli or asparagus spears are fantastic. So good.
Storage & Reheating
Leftovers will keep in an airtight container in the fridge for up to 4 days. You can also freeze them! Assemble the dish but do not bake it. Wrap it tightly in both foil and plastic wrap, and freeze for up to 2 months. Thaw in the fridge overnight before baking as directed. To reheat, the best method is in the oven at 350°F until warmed through (about 20-25 minutes for a refrigerated portion). The microwave works in a pinch, but the texture of the pasta won’t be quite as perfect.
Frequently Asked Questions
- Can I make these stuffed shells ahead of time? Absolutely! You can assemble the entire dish, cover it, and keep it in the refrigerator for up to 24 hours before baking. You might just need to add a few extra minutes to the baking time since it will be cold from the fridge.
- What’s the best way to squeeze the spinach dry? Thaw the spinach completely. Then, place it in the center of a clean kitchen towel or a few layers of paper towels. Gather the edges and twist tightly over the sink, squeezing until no more water comes out. This step is key for avoiding a watery filling!
- Can I use fresh spinach instead of frozen? You sure can! You’ll need about 10 ounces of fresh spinach. Sauté it in a pan with a tiny bit of oil until completely wilted. Let it cool, then squeeze it dry just like you would the frozen stuff.
- Are these vegetarian stuffed shells kid-friendly? In my experience, yes! The creamy, cheesy filling is usually a big hit. You can even blend the spinach into the ricotta mixture more thoroughly if you have picky eaters who might be put off by green flecks.
