Spinach, Pesto, and Beef Stuffed Shells: A Hearty Italian Comfort

The aroma of simmering tomato sauce and bubbling cheese takes me straight back to Sunday dinners at my grandmother’s house. Her manicotti was legendary, a labor of love that always brought the family together. While this recipe for spinach, pesto, and beef stuffed shells isn’t exactly her manicotti, it evokes the same feeling of warmth and comfort. It’s a dish that satisfies both the palate and the soul, and it’s perfect for sharing with loved ones, creating memories that will last a lifetime.

Ingredients

8 ounces manicotti, approximately 12 pasta shells
1 1/2 lbs ground beef
1/3 cup pesto sauce
3 cups marinara sauce
2 (8 ounce) bags fresh spinach
8 ounces cream cheese
4 ounces provolone cheese, sliced and cut into 12 pieces
1/2 cup parmesan cheese, grated
2 cups mozzarella cheese, shredded
Salt and pepper to taste
Olive oil

Equipment Needed

Large pot
Large skillet
Large bowl
Large casserole dish

Instructions

Begin by browning the ground beef in a large skillet over medium-high heat. Season generously with salt and pepper while cooking. Ensure the beef is cooked through and no longer pink.
Once the beef is browned, drain off all excess grease. Removing the grease will help prevent a greasy final dish. Transfer the cooked beef to a large bowl and set aside.
While the beef is browning, bring a large pot of salted water to a boil. Add the manicotti shells and cook according to package directions, until al dente. Be careful not to overcook the shells, as they will continue to cook in the oven.
Once the shells are cooked, drain them thoroughly and set aside. Gently handle the shells to prevent tearing.
Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius).
In the same skillet used to brown the beef, add a drizzle of olive oil over medium heat. Add the fresh spinach to the skillet and sauté until the spinach is completely wilted. This should only take a few minutes. You may need to do this in batches depending on the size of your skillet.
Add the sautéed spinach, pesto sauce, cream cheese, and Parmesan cheese to the bowl with the cooked ground beef. Mix all ingredients together thoroughly until well combined. This mixture will be the delicious filling for your shells.
Pour a thin layer of marinara sauce into the bottom of a large casserole dish. Use just enough sauce to coat the bottom of the dish and prevent the shells from sticking.
Now comes the fun part: stuffing the shells. Take each cooked manicotti shell and carefully fill it with the ground beef and spinach mixture. Use your fingers or a small spoon to pack the filling in tightly.
Place the stuffed shells into the prepared casserole dish in a single layer. Ensure they are not overcrowded, allowing for even cooking.
Top each stuffed shell with a piece of provolone cheese.
Pour the remaining marinara sauce over the stuffed shells, ensuring they are well coated.
Finally, sprinkle the shredded mozzarella cheese evenly over the top of the shells.
Bake in the preheated oven for 45-60 minutes, or until the dish is hot and bubbly and the cheese is melted and lightly golden brown. Keep an eye on the dish to prevent the cheese from browning too quickly. If necessary, you can loosely cover the dish with foil during the last 15 minutes of baking.
Remove from the oven and let cool for a few minutes before serving.

Expert Tips & Tricks

Don’t overcook the pasta shells. Aim for al dente, as they will continue to cook in the oven. Overcooked shells are more prone to tearing when stuffing.
Make ahead: The stuffed shells can be assembled ahead of time and stored in the refrigerator for up to 24 hours before baking. This is a great way to break up the prep work.
Spice it up: Add a pinch of red pepper flakes to the meat mixture for a touch of heat.
Ingredient Swaps: Use ground turkey or Italian sausage instead of ground beef. Ricotta cheese can be used instead of cream cheese. Use your favorite jarred pesto or make your own!
Vegetarian option: Omit the beef and add more sautéed spinach, mushrooms, and other vegetables to the filling.

Serving & Storage Suggestions

Serve the Spinach, Pesto, and Beef Stuffed Shells hot out of the oven, garnished with fresh basil leaves or a sprinkle of Parmesan cheese. A side of garlic bread or a simple green salad complements the dish perfectly.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, bake in a preheated oven at 350°F (175°C) until heated through, or microwave individual portions.

For longer storage, the stuffed shells can be frozen. Wrap them individually in plastic wrap, then place them in a freezer-safe bag or container. They can be frozen for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
