Begin by gently brushing off any dirt from the whole white mushrooms using a dry paper towel. Set them aside, ready for carving.

Using a sturdy straw, poke two eye sockets into each mushroom. Then, use a pairing knife to cut small slits for the nose and scrape lines for teeth.

Preheat your oven to 375°F (190°C). Arrange the carved mushrooms flat side down on a baking tray and bake for about 15 minutes.

While the mushrooms bake, bring a large pot of salted water to a boil and cook the spaghetti according to package instructions, usually 8-10 minutes.

In a separate saucepan, heat your pasta sauce over medium heat until bubbling. Mix in the drained spaghetti and coat well.

To serve, plate the spaghetti and place the baked mushroom skulls atop to create a spooky centerpiece.
