I have to admit — this dish is one of my favorite creepy creations to make during Halloween. The first time I pulled a bubbling tray of these Zombie Guts Stuffed Shells out of the oven, the kids screamed (in delight), and I couldn’t stop laughing. It’s gross-looking in the best way possible — think gooey cheese, rich tomato sauce, and oozing pasta shells that look like… well, zombie guts. But once you take a bite, it’s all comfort food heaven.

These shells are stuffed with a savory, creamy ricotta filling and baked under a blood-red marinara sauce. It’s basically lasagna in disguise — just way more fun and spooky.

What makes this recipe special is how it balances playful Halloween vibes with seriously delicious flavor. You get the drama of a haunted dinner table, but the taste of an Italian classic that could hold its own any night of the year.

Tools You’ll Need

Large pot – for boiling the jumbo pasta shells. (They need space so they don’t stick together!)
Mixing bowls – one for the cheese filling, another for your “blood” sauce.
Baking dish (9×13 inch / 23×33 cm) – where all the zombie action happens.
Spoon or piping bag – for filling the shells easily. I usually just use a spoon; less cleanup!
Aluminum foil – to cover the dish while baking, keeping it moist and gooey.
Oven mitts – trust me, you’ll want to avoid actual burns when handling your “zombie guts.”

Ingredients

For the Stuffed Shells:

20 jumbo pasta shells (about 250 g)
1 ½ cups ricotta cheese (340 g)
1 cup shredded mozzarella (113 g)
½ cup grated Parmesan (50 g)
1 egg
2 cloves garlic, minced
1 tablespoon fresh parsley, chopped (or 1 teaspoon dried)
Salt and black pepper, to taste

For the “Zombie Blood” Sauce:

3 cups marinara or pasta sauce (700 g)
1 tablespoon olive oil
½ teaspoon red pepper flakes (optional, for a spicy “bite”)
½ teaspoon dried oregano
A few drops of green or black food coloring (for that undead tint, optional)

For the “Guts Effect”:

1 cup mozzarella cheese (113 g), shredded for topping
¼ cup extra marinara, drizzled for a bloody look

Step-by-Step Instructions

1. Cook the Pasta Shells

Fill a large pot with salted water and bring it to a boil. Drop in your jumbo shells and cook them until just al dente — about 9 minutes. They’ll finish cooking in the oven. Drain and lay them on parchment paper so they don’t stick.

Tip: Don’t overcook the shells or they’ll tear when you stuff them. Think of them like delicate zombie organs — handle with care.

2. Prepare the “Zombie Blood” Sauce

In a saucepan, heat olive oil over medium heat. Add marinara, oregano, and red pepper flakes. Stir it until it’s heated through. For extra Halloween flair, stir in a few drops of green or black food coloring — it gives the sauce that eerie undead hue.

I usually taste it here and adjust seasoning — you want the sauce flavorful enough to carry the whole dish.

3. Mix the Filling

In a large bowl, combine ricotta, mozzarella, Parmesan, egg, garlic, parsley, salt, and pepper. Mix until creamy and smooth. It should look thick and spreadable — like cheesy stuffing for your zombie shells.

4. Stuff the Shells

Using a spoon (or piping bag, if you’re fancy), fill each pasta shell with about 2 tablespoons of the ricotta mixture. I love this part — it’s oddly satisfying watching each shell come to life (or death).

5. Assemble the Dish

Spread a thin layer of the “blood sauce” in the bottom of your baking dish. Arrange the stuffed shells in a single layer, open side up. Pour the rest of the sauce on top, making sure it seeps into all the nooks and crannies. Sprinkle mozzarella over everything.

For the final zombie touch, drizzle a little extra sauce across the top — it’ll bake into realistic “blood trails.”

6. Bake the Guts

Cover with foil and bake in a preheated oven at 375°F (190°C) for 25 minutes. Then remove the foil and bake another 10 minutes, until the cheese bubbles and the sauce looks thick and gory.

When you pull it out, the sight alone is worth it — bubbling red sauce, melty cheese, and pasta shells oozing with filling.

Serving Ideas

Serve with garlic breadsticks (call them “bone sticks” for fun).
Add a side salad for freshness — it balances all that cheesy richness.
Drizzle extra marinara on top right before serving for extra “blood effect.”
For Halloween parties, serve each shell in a small bowl and label them “Zombie Guts Cups.”

Variations & Customizations

Meat Lovers: Add cooked ground beef or sausage to the sauce.
Veggie Style: Mix in chopped spinach, mushrooms, or roasted peppers to the filling.
Spicy Twist: Add hot sauce or crushed red chili flakes to make it bite back.
Vegan Option: Swap ricotta for tofu blended with nutritional yeast and lemon juice.

Make-Ahead & Storage

Make-Ahead: Assemble the dish up to a day in advance. Cover and refrigerate. When ready to bake, add 10 minutes to the cook time.
Storage: Store leftovers in an airtight container in the fridge for up to 4 days.
Freezing: Freeze baked or unbaked shells for up to 2 months. Reheat straight from frozen at 350°F (175°C) for about 40 minutes.

Pro Tips (and Mistakes to Avoid)

Don’t skip the sauce layer at the bottom — it keeps the shells from sticking or drying out.
Let the dish rest for 5–10 minutes after baking — the filling sets and makes serving easier.
Use a piping bag if you’re short on patience. It’s cleaner and faster than spooning.
Avoid overfilling the shells. They’ll burst open like… well, real guts.
For ultimate creep factor: Add a drop of green food dye to the ricotta filling too. It’ll ooze out with zombie flair.
