Ingredients

Scale

Pasta

  • 12 oz Fettuccine pasta

Vegetables & Aromatics

  • 3 large Yellow onions, peeled and thinly sliced
  • 3 cloves Garlic, minced

Fats & Dairy

  • 2 tbsp Olive oil
  • 2 tbsp Butter
  • 1 cup Heavy cream
  • 1 cup Parmesan cheese, freshly grated

Seasonings

  • Salt, to taste
  • Freshly ground black pepper, to taste

Instructions

  1. Prepare the Onions: Peel and thinly slice the yellow onions. Heat olive oil and butter in a large skillet over medium-low heat. Add the onions, stirring occasionally, and cook slowly for about 30 to 40 minutes, until they become deep golden and caramelized. Patience is key to developing the natural sweetness and rich flavor.
  2. Cook the Fettuccine: While the onions cook, bring a large pot of salted water to a boil. Add the fettuccine and cook until al dente according to package instructions. Reserve 1 cup of pasta water before draining.
  3. Make the Creamy Sauce: To the caramelized onions, add minced garlic and cook for 1 minute until fragrant. Pour in the heavy cream and stir gently, allowing the sauce to thicken slightly. Stir in grated Parmesan cheese until melted and fully incorporated. Season with salt and freshly ground black pepper to taste.
  4. Combine Pasta and Sauce: Add the drained fettuccine to the skillet with the onion cream sauce. Toss gently to coat evenly. If the sauce is too thick, loosen it with some reserved pasta water until you reach the desired creamy consistency.
  5. Serve and Enjoy: Plate the pasta, garnishing with a generous sprinkle of fresh Parmesan and freshly cracked black pepper. For extra flavor and color, add optional garnishes such as chopped parsley or a drizzle of olive oil. Serve immediately for best taste and texture.

Notes

  • Low and slow: Take your time caramelizing the onions to avoid bitterness and ensure even color.
  • Reserve pasta water: Use the starchy water to adjust sauce consistency and help it cling to the noodles.
  • Use fresh Parmesan: Grate your own for better melt and flavor.
  • Don’t overcrowd the pan: Allow onions enough space to caramelize rather than steam.
  • Taste as you go: Season gradually and adjust salt and pepper while cooking.
