**History:**
Fettuccine Carbonara has deep roots in Roman cuisine, dating back to the mid-20th century. Originally known as “pasta alla carbonara,” it is believed to have been created by Italian coal workers (carbonai), hence the name. Today, it’s renowned worldwide for its simplicity and unmatched flavor.

**Ingredients:**
– 12 oz (340g) fettuccine pasta
– 4 large eggs
– 1 cup (100g) grated Pecorino Romano cheese
– 1 cup (100g) grated Parmesan cheese
– 200g pancetta or guanciale (Italian cured pork), diced
– 4 cloves garlic, minced
– Freshly ground black pepper, to taste
– Fresh parsley, finely chopped (for garnish)

**Instructions:**

1. **Cook the Pasta:** Begin by cooking the fettuccine pasta in a large pot of salted boiling water until al dente. Drain and set aside, reserving about 1/2 cup of pasta water.

2. **Prepare the Sauce:** In a separate bowl, whisk together the eggs, grated Pecorino Romano cheese, and grated Parmesan cheese. Season generously with freshly ground black pepper. Set aside.

3. **Cook the Pancetta:** In a large skillet over medium heat, cook the diced pancetta or guanciale until it turns crispy and golden brown. Remove from heat and discard excess fat.

4. **Combine Everything:** Return the cooked pasta to the skillet with the crispy pancetta. Toss in the minced garlic and stir well.

5. **Add the Egg Mixture:** Immediately after, pour the egg and cheese mixture over the pasta. The heat from the pasta and pancetta will cook the eggs, creating a luscious, creamy sauce. If the sauce is too thick, gradually add reserved pasta water until desired consistency is achieved.

6. **Serve and Garnish:** Plate the Fettuccine Carbonara and sprinkle with fresh parsley for a burst of color and flavor.

**Variations:**

– **Vegetarian Carbonara:** Substitute pancetta with sautéed mushrooms or zucchini for a meatless twist on this classic.

– **Spaghetti Carbonara:** Replace fettuccine with spaghetti if you prefer a thinner pasta.

– **Bacon Carbonara:** If pancetta or guanciale is hard to find, bacon can be used as a flavorful alternative.

Incorporate these variations to make Fettuccine Carbonara your own signature dish.
