How to Make Caramelized Onion & Garlic Spaghetti
Cook Pasta: In a large pot of boiling salted water, cook the spaghetti according to package instructions until al dente, usually about 8-10 minutes. Drain and set aside, reserving a cup of pasta water.
Sauté Onions: In a large skillet, heat olive oil over medium heat. Add sliced onions and cook, stirring occasionally, until they become soft and caramelized, about 15-20 minutes. They should be a golden brown color for that rich sweetness.
Add Garlic: Stir in minced garlic and cook for 1-2 minutes until fragrant, being careful not to let it burn. The aroma is enticing and signals you're on the right track!
Combine Pasta and Sauce: Add the cooked spaghetti directly to the skillet with the caramelized onions and garlic. Toss everything together, and if the pasta seems dry, add a bit of the reserved pasta water to create a silky sauce.
Stir in Butter and Cheese: Remove the skillet from heat, then stir in butter and Parmesan cheese until melted and creamy. Adjust seasoning with salt and freshly cracked black pepper to taste.
Garnish and Serve: Plate your spaghetti and sprinkle with fresh herbs, if desired. Serve immediately to enjoy the warmth and depth of flavor.
