Start by bringing a large pot of salted water to a boil. Add the pasta and cook until al dente, about 8 minutes, until it feels firm yet tender to the bite.
While the pasta cooks, heat olive oil in a skillet over medium heat. Add the chopped onion and sauté until it becomes translucent and fragrant, about 3-4 minutes, with a gentle sizzle and sweet aroma filling the air.
Add the minced garlic to the skillet and cook for about 30 seconds, stirring constantly, until it turns fragrant and slightly golden, avoiding burning.
Pour in the crushed fire-roasted tomatoes and stir to combine. Sprinkle in red pepper flakes, then let the sauce simmer gently, bubbling softly and thickening slightly, for about 10 minutes.
Once the pasta is cooked, drain it in a colander and then add it directly to the skillet with the sauce. Toss everything together with a wooden spoon, ensuring the noodles are coated evenly, and let it simmer together for 2 minutes to meld flavors.
Sprinkle the shredded cheese over the pasta and stir gently until melted and gooey, creating a spooky, melty finish.
Remove from heat and sprinkle with chopped fresh herbs for a burst of color and freshness. Give it a final toss to distribute evenly.
Serve hot in bowls, showing off the vibrant red sauce and cheesy topping, perfect for a fun Halloween dinner.
