## Ingredients

* 1 pound pasta (such as spaghetti, linguine, or fettuccine)
* 2 large yellow onions, thinly sliced
* 1 head of garlic
* 4 tablespoons olive oil, divided
* 1/2 cup dry white wine (optional, but recommended)
* 1/4 cup vegetable broth or pasta water
* 2 tablespoons butter
* 1/4 cup grated Parmesan cheese, plus more for serving
* Salt and freshly ground black pepper to taste
* Fresh parsley, chopped (for garnish)
* Red pepper flakes (optional, for a touch of heat)

## Equipment

* Large pot for boiling pasta
* Large skillet or Dutch oven
* Baking sheet
* Aluminum foil
* Garlic press (optional)

## Instructions

### 1. Roast the Garlic

* Preheat your oven to 400°F (200°C).
* Cut off the top of the garlic head, exposing the cloves. Drizzle with 1 tablespoon of olive oil and wrap tightly in aluminum foil.
* Roast for 45-60 minutes, or until the garlic is soft and fragrant. The cloves should be easily squeezed out of their skins.
* Let the garlic cool slightly before handling.

### 2. Caramelize the Onions

* While the garlic is roasting, start caramelizing the onions. Heat the remaining 3 tablespoons of olive oil and the butter in a large skillet or Dutch oven over medium-low heat. The key to perfect caramelized onions is low and slow cooking.
* Add the sliced onions to the skillet and stir to coat them in the oil. Sprinkle with a pinch of salt. Salt helps to draw out the moisture from the onions, which speeds up the caramelization process.
* Cook the onions, stirring occasionally, for about 45-60 minutes, or until they are a deep golden brown color and very soft. The onions will gradually shrink in size and become increasingly sweet. Be patient! This process takes time.
* If the onions start to stick to the bottom of the pan, add a tablespoon of water or vegetable broth to deglaze the pan and scrape up any browned bits. This will add even more flavor to the onions.

### 3. Cook the Pasta

* While the onions are caramelizing, bring a large pot of salted water to a boil. Add the pasta and cook according to the package directions until al dente. Al dente means “to the tooth” in Italian, and it refers to pasta that is cooked through but still firm to the bite. This texture is ideal for absorbing the sauce.
* Reserve about 1/2 cup of pasta water before draining the pasta. This starchy water will help to create a creamy and emulsified sauce.
* Drain the pasta and set aside.

### 4. Combine the Ingredients

* Once the garlic is cool enough to handle, squeeze the roasted garlic cloves out of their skins into a small bowl. Mash the garlic with a fork until it forms a smooth paste.
* Add the mashed roasted garlic to the skillet with the caramelized onions. Stir to combine.
* If using, pour the white wine into the skillet and let it simmer for a few minutes, scraping up any browned bits from the bottom of the pan. The alcohol will evaporate, leaving behind a delicious flavor.
* Add the drained pasta to the skillet and toss to coat it in the onion and garlic mixture.
* Add the reserved pasta water, a little at a time, until the sauce reaches your desired consistency. The pasta water will help to create a creamy and emulsified sauce that clings to the pasta.
* Stir in the Parmesan cheese and season with salt and freshly ground black pepper to taste. Add a pinch of red pepper flakes if you like a little heat.

### 5. Serve

* Serve the pasta immediately, garnished with fresh parsley and extra Parmesan cheese. A drizzle of olive oil is also a nice touch.

## Tips for Perfect Caramelized Onions

* **Use the Right Pan:** A heavy-bottomed skillet or Dutch oven is ideal for caramelizing onions. This type of pan distributes heat evenly and prevents the onions from burning.
* **Low and Slow is Key:** The secret to perfect caramelized onions is to cook them over low heat for a long period of time. This allows the onions to slowly release their sugars and develop a deep, rich flavor.
* **Don’t Rush the Process:** Caramelizing onions takes time, so be patient. Don’t try to speed up the process by turning up the heat, as this will only result in burnt onions.
* **Stir Occasionally:** Stir the onions occasionally to prevent them from sticking to the bottom of the pan. However, avoid stirring them too frequently, as this can prevent them from caramelizing properly.
* **Deglaze the Pan:** If the onions start to stick to the bottom of the pan, add a tablespoon of water or vegetable broth to deglaze the pan and scrape up any browned bits. This will add even more flavor to the onions.

## Variations and Additions

* **Add Vegetables:** Sautéed mushrooms, spinach, or asparagus would be delicious additions to this pasta dish.
* **Add Protein:** Grilled chicken, shrimp, or sausage would add protein and make this a more complete meal.
* **Add Cheese:** In addition to Parmesan cheese, you could also add goat cheese, ricotta cheese, or mozzarella cheese.
* **Use Different Herbs:** Instead of parsley, try using fresh thyme, rosemary, or oregano.
* **Make it Vegan:** Omit the Parmesan cheese and use a plant-based butter substitute to make this dish vegan.

## Serving Suggestions

* Serve this pasta as a main course for dinner.
* Serve it as a side dish alongside grilled meat or fish.
* Serve it as a potluck dish.
* Pack it for lunch.

## Storage and Reheating

* **Storage:** Store leftover pasta in an airtight container in the refrigerator for up to 3 days.
* **Reheating:** Reheat the pasta in a skillet over medium heat, adding a splash of water or broth if needed to prevent it from drying out. You can also reheat it in the microwave.
