How to Serve Spinach Stuffed Shells
To serve Spinach Stuffed Shells, simply dish out a few shells onto each plate. You can garnish with extra grated parmesan cheese and fresh basil for added flavor. Pair them with a side salad or garlic bread to complete the meal.
How to Store Spinach Stuffed Shells
If you have leftovers, store them in an airtight container in the refrigerator. They can last for up to 3-4 days. You can also freeze the stuffed shells before baking. Just assemble everything and cover it tightly. When you’re ready to eat, bake from frozen, adding a little extra baking time.
Tips to Make Spinach Stuffed Shells
- Make sure not to overcook the pasta shells; they should be al dente so they don’t break when you stuff them.
- Feel free to add other ingredients to the ricotta mixture, such as chopped artichokes, diced tomatoes, or even different herbs.
- If you want a creamier sauce, mix some of the marinara with a little cream before pouring it over the shells.
Variation
For a healthier twist, you can use whole wheat or gluten-free pasta shells. You can also replace the ricotta cheese with cottage cheese for a lighter filling.
