How to Make Red Spaghetti An easy and super tasty recipe!

Prepare the noodles according to the package instructions in salted water, reserving a cup of the pasta water before draining.
In a large skillet, heat the olive oil over medium heat, add the onion, and cook until translucent.
Add the garlic and cook for about 30 seconds, or until fragrant.
Pour the crushed or diced tomatoes into the skillet. If using whole tomatoes, you can break them up with a wooden spoon.
Add the sugar (if using), salt, pepper, oregano, and basil, stirring well.
Reduce the heat to medium-low and simmer the sauce for about 15 to 20 minutes, stirring occasionally. If the sauce is too thick, you can add a little of the pasta water to adjust the consistency.
Taste the sauce and adjust the seasonings to your liking.
Once the noodles are ready, drain them and toss them with the sauce.
Serve the noodles on individual plates and sprinkle with grated Parmesan cheese, if desired.
Additional Tips:
The quality of the tomatoes is the key to a delicious sauce. Opt for ripe, juicy tomatoes, either good-quality canned chopped tomatoes or fresh tomatoes if they are in season.
Let the sauce simmer for at least 15 to 20 minutes so the flavors blend and intensify. This also helps the sauce thicken properly.
Once the pasta is ready, toss it well with the hot sauce so that each strand is well coated and absorbs the flavors of the sauce.
