- 20 jumbo pasta shells: The perfect size to hold the generous spinach and cheese filling without breaking apart.

- ¼ teaspoon black pepper: Gives a gentle spicy note that balances the creamy filling.

How to Make Decadent Spinach-Stuffed Shells Recipe
Step 1: Prepare the Pasta Shells
Begin by preheating your oven to 375°F (190°C). Cook the jumbo pasta shells in salted boiling water until they are just al dente—this ensures they hold their shape and fill nicely without getting mushy. Drain carefully and set them aside to cool slightly so they’re easy to handle during stuffing.
Step 2: Sauté the Spinach and Garlic
While the pasta cooks, heat olive oil in a skillet over medium heat. Add the minced garlic and sauté for about 30 seconds until fragrant but not browned—that delicate aroma is key. Stir in the chopped spinach and cook for around 2 minutes, just until wilted. Remove from heat and allow the mixture to cool a bit before mixing it with the cheeses.
Step 3: Mix the Filling
In a medium bowl, combine the sautéed spinach and garlic with ricotta, mozzarella, Parmesan, egg, salt, and pepper. Mix everything together well until you have a creamy, cohesive filling bursting with rich flavors and perfect seasoning. This filling is the heart and soul of your Decadent Spinach-Stuffed Shells Recipe, so take your time to get it just right.
Step 4: Stuff the Shells and Assemble
Spread one cup of marinara sauce over the bottom of a 9 by 13-inch baking dish to keep the shells moist during baking. Carefully stuff each pasta shell with about two tablespoons of the cheese and spinach mixture and nestle them into the dish. Once they are all filled and snug, pour the remaining marinara sauce evenly over the top. Sprinkle generously with additional mozzarella cheese for that irresistibly gooey and golden finish.
Step 5: Bake to Perfection
Cover your baking dish with foil and pop it in the oven for 25 minutes. This step lets all the flavors meld and the filling heat through perfectly. After 25 minutes, remove the foil and bake uncover for another 10 minutes until the sauce is bubbly and the cheese topping is beautifully golden and slightly crisp. Your Decadent Spinach-Stuffed Shells Recipe is now ready to wow!

FAQs
Can I use frozen spinach instead of fresh for this Decadent Spinach-Stuffed Shells Recipe?
Absolutely! Frozen spinach works well as long as you thaw it fully and squeeze out excess moisture before mixing it in. This prevents the filling from becoming watery and keeps the flavors concentrated.

If jumbo shells are hard to find, you can substitute large manicotti tubes or even use smaller shells stuffed with less filling, though the texture and size experience will change slightly.
How can I make this dish gluten-free?
Simply use gluten-free jumbo pasta shells available at many grocery stores. The rest of the ingredients are naturally gluten-free, so your Decadent Spinach-Stuffed Shells Recipe remains delicious and safe for gluten sensitivity.
