Ready to bring a piece of my family’s kitchen into yours? Follow these steps, and you’ll have a delightful meal on your table in no time:

1. In a large pot, bring salted water to a boil. Add the pasta and cook until al dente, according to package instructions. Drain and set aside, reserving 1/2 cup of the pasta water.
2. In a large skillet over medium heat, heat the olive oil. Add the onions and a pinch of salt, cooking until they become translucent and tender, about 8-10 minutes. Stir occasionally to avoid burning.
3. Add the minced garlic and red pepper flakes to the skillet, cooking for another 2-3 minutes until fragrant. This step always reminds me of my mother’s kitchen, where the aroma of garlic meant something delicious was on its way.
4. Pour in the broth and bring the mixture to a gentle simmer. Let it reduce slightly, about 5 minutes, allowing the flavors to meld together beautifully.
5. Toss in the cooked pasta, reserved pasta water, and Parmesan cheese. Stir until the pasta is well coated with the onion sauce. Season with salt and pepper to taste.
6. Serve hot, garnished with fresh parsley for a touch of color and freshness.

Remember, the key to this dish is patience. Letting the onions caramelize slowly is what builds the rich, sweet flavor that makes this pasta recipe onion so irresistible.
