How to Make Stuffed Shells from Scratch
First: Preheat oven to 350F. Cook pasta shells “al dente” according to package directions. Drain and rinse with cold water. Set aside.
Second: While the pasta is cooking, sauté the onion, squash, zucchini, and bell pepper with olive oil over medium heat. Add spinach and stir until the spinach wilts. Remove from heat and cool slightly.
Third: In a separate bowl, combine the ricotta, mozzarella, egg, and spices. Stir in the vegetable mixture.
Fourth: Spread 3/4 cup of pasta sauce in the bottom of your baking dish. Stuff the pasta shells with 2-3 tablespoons of vegetable cheese mixture. Place the shells in the baking dish. Top with remaining sauce.
Fifth: Cover baking dish with aluminum foil and bake at 350F for 35 minutes. Uncover, sprinkle with parmesan cheese and bake uncovered for an additional 10 minutes. Remove from oven, cool slightly, and serve!

How long do they last?
Store any leftovers in the fridge, in an airtight container, for up to 4 days. Reheat in the microwave or oven until warmed through.
Can I freeze them?
This recipe is the perfect meal to make ahead or double the batch and throw one in the freezer for those busy nights.
To freeze these stuffed shells, prepare the shells according to directions but do not bake. After you stuff the shells, cover the pan with foil and place it in the freezer.
When you’re ready to eat, bake uncovered for 45 minutes at 350 degrees or until bubbly and browned on the top. They cook faster if you thaw overnight in the fridge.
Substitutions/Variations
Spinach- If spinach isn’t your thing, or you fight your husband and kids daily to eat the green stuff, go ahead and leave it out! Or chop it up really fine and sneak it into the sauce.
Marinara-If you’re feeling extra ambitious, try a delicious homemade marinara in place of a store-bought sauce.
Herbs-Italian seasoning is my favorite and makes things really quick with this recipe. But use whatever herbs you like best. If you have fresh herbs, feel free to use those instead of dried ones.
TIP: If you are using fresh herbs, be sure to use double the amount as you would dried herbs due to the high water content. They will cook down a lot.
Cheese- Try using a different cheese in place of mozzarella. Romano, parmesan or provolone are all tasty as well. You can also replace the ricotta with cream cheese or cottage cheese!

Tips for No Leftovers
- To keep your shells from falling apart when you stuff them, slightly undercook the shells, just to al dente as they will continue to cook when they go into the oven.
- For extra smooth melted cheese, shred your own rather than buying the pre-shredded bags of cheese.
- Make your own marinara sauce to really spice it up! This is a fantastic Simple Homemade Marinara recipe.
- To get the job done quickly with less mess, use a piping bag or Ziploc bag with the tip cut off to fill your shells.
- Only choose ingredients you like. If you don’t like a certain herb, try a different herb. Replace Ricotta with cream cheese or cottage cheese.
- Double the recipe and make a second batch to freeze later!
