Step‑by‑Step Instructions for Spinach Stuffed Shells
Step 1: Cook the Pasta
Bring a large pot of salted water to a rolling boil and add the jumbo pasta shells. Cook them for about 8-9 minutes, slightly less than the package instructions, to keep them firm. Drain the shells and drizzle a little vegetable oil over them to prevent sticking, then set them aside to cool.
Step 2: Sauté Aromatics
In a large frying pan, heat 2 tablespoons of olive oil over medium heat. Add 3 cloves of minced garlic and ½ chopped onion, cooking for 3-5 minutes until they’re fragrant and the onion is translucent. This step infuses the filling with a delicious flavor while you prepare the spinach.
Step 3: Cook the Spinach
Add 8 ounces of fresh spinach, along with ½ teaspoon of salt and ½ teaspoon of pepper, to the sautéed garlic and onion mixture. Stir and cook for another 2-3 minutes until the spinach is wilted and bright green. Then, transfer this mixture to a mixing bowl to cool slightly.
Step 4: Prepare the Filling
To the cooled spinach mixture, add 1 block of softened cream cheese, 1 teaspoon of garlic powder, 1 teaspoon of onion powder, and 2 teaspoons of Italian seasoning. Incorporate 8 ounces of shredded triple cheddar cheese into the mixture, stirring until everything is creamy and well combined for your Spinach Stuffed Shells filling.
Step 5: Preheat the Oven
While the filling cools, preheat your oven to 350°F (175°C). This temperature will ensure the stuffing is heated through while the cheese on top gets perfectly golden.
Step 6: Assemble the Dish
Spread a thin layer of spaghetti sauce (about ½-1 cup) on the bottom of a 9x13 inch baking dish. Carefully fill each cooled pasta shell with the creamy spinach mixture, then place them seam-side up in the prepared dish. Arrange the stuffed shells snugly for even baking.
Step 7: Top with Sauce and Cheese
Pour the remaining spaghetti sauce over the stuffed shells, ensuring a good coverage. Sprinkle 1-2 cups of shredded mozzarella cheese generously on top, making sure each shell is covered for that delightful melty topping.
Step 8: Bake to Perfection
Cover the baking dish with foil and place it in the preheated oven. Bake for 25 minutes covered, then remove the foil and bake for an additional 10-15 minutes until the sauce bubbles and the cheese is golden brown. Your Spinach Stuffed Shells are now ready to be enjoyed!

Make Ahead Options
These Creamy Spinach Stuffed Shells are perfect for meal prep enthusiasts looking to simplify their weeknight dinners! You can prepare the filling (spinach, cream cheese, and seasonings) a day ahead and refrigerate it, ensuring it stays fresh and just as delicious when you’re ready to assemble. For an even more convenient option, you can assemble the entire dish and refrigerate it for up to 24 hours before baking. Just cover it tightly with foil to maintain moisture and flavor. When you're ready to serve, bake directly from the fridge, adding an extra 10-15 minutes to the baking time, and enjoy a comforting meal with minimal effort!
How to Store and Freeze Spinach Stuffed Shells
Fridge: Store leftover Spinach Stuffed Shells in an airtight container for up to 3 days. Reheat in the oven or microwave until warmed through.
Freezer: Assemble the shells but do not bake; wrap tightly or use a freezer-safe dish to prevent freezer burn. They can be frozen for up to 3 months.
Reheating: If frozen, increase baking time by 10-15 minutes when you're ready to enjoy them. Ensure they reach an internal temperature of 165°F (74°C) for safe consumption.
Airtight Storage: For best results, place parchment paper between layers of stuffed shells before covering to maintain texture and prevent sticking during storage.

Spinach Stuffed Shells Recipe FAQs
How should I select and ensure the freshness of my spinach?
Absolutely! When choosing fresh spinach, look for bright green leaves free of dark spots or wilting. If you can, opt for organic spinach to avoid pesticides. A good bunch should feel firm and crisp, and it’s best to use it within 3-5 days for peak freshness.
What is the best way to store cooked Spinach Stuffed Shells?
Very! Store leftover Spinach Stuffed Shells in an airtight container in the fridge, where they will stay fresh for up to 3 days. Reheat in the oven or microwave until warmed through. Just ensure they are covered to maintain moisture.
Can I freeze Spinach Stuffed Shells for later?

What can I do if my filling is too runny?
No worries! If your filling seems too runny, add some breadcrumbs or an extra block of cream cheese to help absorb the excess moisture. You can also try chilling the filling in the fridge for about 30 minutes before stuffing the shells, which helps firm it up.
Are there any dietary considerations for Spinach Stuffed Shells?
