Begin by gently brushing off any dirt from the whole white button mushrooms using a dry paper towel.

Using a straw, poke eye sockets into each mushroom to create the spooky skull features and carve out mouth and nose details.

Preheat your oven to 375°F (190°C).

Line a baking tray with oil and place the carved mushrooms flat side down. Bake for about 15 minutes until tender.

Bring a pot of salted water to a boil and cook the spaghetti according to package instructions for 8-10 minutes.

Heat your jarred pasta sauce in a separate saucepan until warmed through. Toss cooked spaghetti in the sauce.

Plate the saucy spaghetti and top with the spooky baked mushroom skulls, arranging them artistically.
