Cook the spaghetti according to package directions until al dente. Drain and set aside.
1 pound Spaghetti
In a large skillet, heat olive oil over medium-high heat. Add the diced onion, minced garlic, and crushed red pepper flakes, stirring constantly until the onion is soft and translucent (about 3 minutes). Be careful not to burn the garlic.
2 Tablespoon Olive Oil, ¼ cup Diced Onion, 2 cloves Fresh Garlic, ¼ teaspoon Crushed Red Pepper
Stir in the crushed tomatoes, sugar, basil, salt, and black pepper. Mix well to combine all the flavors.
1 28 ounce Crushed Tomatoes, 1 teaspoon Sugar, 1 Tablespoon Basil, ½ teaspoon Salt, ¼ teaspoon Black Pepper
Reduce the heat to low and let the sauce simmer for 25 minutes, stirring occasionally. If the sauce is too thick, add ¼ cup of water (or chicken broth) to adjust the consistency. For a thicker sauce (ideal for pizza), simmer longer.
¼ cup Water
Toss the cooked spaghetti with the sauce or ladle the sauce over individual servings. Top with freshly grated Parmesan cheese and basil ribbons for the perfect finishing touch.
