Beef and Spinach Stuffed Manicotti is a warm, hearty baked pasta dish filled with seasoned ground beef, spinach, ricotta, mozzarella, Parmesan, garlic, and Italian herbs. The stuffed pasta shells bake in marinara sauce until the filling turns creamy, the pasta becomes tender, and the cheese on top melts into a bubbly golden layer.
This is the kind of dinner that feels comforting and homemade without being too complicated. The filling has plenty of savory flavor from the beef, freshness from the spinach, and creaminess from the cheese. Once everything bakes together, the sauce, pasta, and filling turn into a cozy family-style meal.
It is a great recipe for Sunday dinner, holidays, meal prep, or anytime you want a baked pasta dish that feels filling and special. Serve it with garlic bread, Caesar salad, roasted vegetables, or a simple green salad.
Ingredients You’ll Need
Manicotti Shells
Manicotti shells are large pasta tubes made for stuffing. Cook them just until firm-tender so they are flexible but not too soft.
Ground Beef
Lean ground beef gives the filling a rich, savory flavor without too much grease.
Spinach
Fresh spinach works well because it cooks quickly. Frozen spinach can also be used, but it must be thawed and squeezed dry.
Ricotta Cheese
Ricotta makes the filling creamy and helps everything hold together.
Mozzarella Cheese
Mozzarella gives the filling and topping a smooth melted texture.
Parmesan Cheese
Parmesan adds salty, savory flavor and helps the filling taste more complete.
Marinara Sauce
Use a marinara sauce you enjoy because it gives the dish most of its tomato flavor.
Egg
One egg helps bind the filling so it stays inside the shells after baking.
Garlic and Onion
These build flavor in the beef mixture and make the filling taste homemade.
Italian Seasoning
Italian seasoning adds classic baked pasta flavor with herbs like oregano, basil, and thyme.
Fresh Parsley or Basil
Fresh herbs brighten the finished dish and make it look more appetizing.

How to Make Beef and Spinach Stuffed Manicotti
Step 1: Cook the Manicotti Shells
Bring a large pot of salted water to a boil.
Add the manicotti shells and cook them 1 to 2 minutes less than the package directions. They should be soft enough to fill but still firm enough to hold their shape.
Drain the shells and rinse them gently with cool water. Place them on a lightly oiled tray or parchment-lined baking sheet so they do not stick together.
Be gentle with the shells. They can tear if they are overcooked or handled roughly.
Step 2: Cook the Beef and Spinach
Heat olive oil in a large skillet over medium heat.
Add the ground beef and cook until browned, breaking it into small crumbles as it cooks. Add the onion and cook until softened, about 2 to 3 minutes.
Stir in the garlic and cook for about 30 seconds, just until fragrant.
Add the chopped spinach, Italian seasoning, salt, black pepper, and red pepper flakes if using. Cook until the spinach wilts and the mixture no longer looks watery.
Remove the skillet from the heat and let the mixture cool for a few minutes. Ground beef should be cooked to 160°F if checking with a food thermometer.
Step 3: Mix the Filling
In a large mixing bowl, stir together ricotta, mozzarella, Parmesan, egg, and chopped parsley or basil.
Add the cooled beef and spinach mixture. Stir until the filling looks evenly combined.
The filling should be thick, creamy, and easy to spoon or pipe into the manicotti shells.
If the filling looks loose, let it sit for a few minutes or add a little extra Parmesan.
Step 4: Stuff the Manicotti
Spread 1 cup of marinara sauce into the bottom of a 9×13-inch baking dish.
Fill each manicotti shell with the beef and spinach cheese mixture. A small spoon works, but a piping bag or zip-top bag with the corner cut off makes this step much easier.
Place the filled shells in the baking dish in a single layer.
Do not pack the shells too tightly. A little space helps the sauce move around the pasta while it bakes.
Step 5: Add Sauce and Cheese
Pour the remaining marinara sauce over the stuffed shells.
Sprinkle mozzarella and Parmesan over the top.
Cover the baking dish with foil. Try to keep the foil from pressing directly into the cheese. If needed, lightly spray the underside of the foil with cooking spray.
Step 6: Bake the Manicotti
Bake at 375°F for 25 minutes covered.
Remove the foil and bake for another 10 to 15 minutes, or until the sauce is bubbling and the cheese is melted.
For a golden top, broil for 1 to 2 minutes at the end. Watch closely because cheese can brown quickly.
Let the manicotti rest for 5 to 10 minutes before serving. This helps the filling settle and makes the shells easier to lift from the dish.
Tips for the Best Stuffed Manicotti
Do not overcook the pasta shells. Slightly firm shells are easier to fill and hold up better during baking.
Let the beef mixture cool before mixing it with ricotta. Hot beef can loosen the cheese mixture too much.
Remove extra moisture from spinach. If using frozen spinach, squeeze it very dry before adding it.
Use enough marinara sauce. The pasta needs sauce around it to stay tender in the oven.
Use a piping bag for cleaner stuffing. It is faster and helps prevent shells from tearing.
Let the dish rest before serving. This keeps the filling inside the pasta instead of spilling out.
Use freshly shredded mozzarella if possible. It melts better and gives a smoother topping.

Make-Ahead Instructions
You can assemble this manicotti up to 24 hours ahead.
Prepare the dish, cover it tightly, and refrigerate it until ready to bake. Let it sit at room temperature for about 20 minutes while the oven preheats.
If baking straight from the refrigerator, add 5 to 10 extra minutes to the covered baking time.
How to Store Leftovers
Store leftover manicotti in an airtight container in the refrigerator for up to 4 days.
Keep some sauce with the pasta so it does not dry out.
How to Reheat
Reheat individual portions in the microwave until warm.
For the best texture, place the manicotti in a covered baking dish and warm at 325°F until heated through.
Add a spoonful of marinara sauce before reheating if the pasta looks dry.
Frequently Asked Questions
Can I use jumbo shells instead of manicotti?
Yes. Jumbo shells work well with the same filling and are often easier to stuff.
Can I use frozen spinach?
Yes. Thaw it completely and squeeze out as much water as possible before using.
Can I use cottage cheese instead of ricotta?
Yes. Cottage cheese can work, especially if blended smooth first. Ricotta gives a more classic texture.
Can I use ground turkey instead of beef?
Yes. Ground turkey works well for a lighter version.
Can I make this ahead?
Yes. Assemble it up to 24 hours ahead and bake when ready.
Why did my manicotti tear?
The shells were likely overcooked or handled too roughly. Cook them firm-tender and fill them gently.
Can I make this without egg?
Yes. The filling will be a little softer, but it can still work. Add extra Parmesan if you want it thicker.
