Creamy Caramelized Onion Pasta is made by slowly caramelizing onions until golden and sweet. While the onions cook, pasta is boiled and set aside. A creamy sauce is prepared with garlic, heavy cream, and Parmesan cheese. The caramelized onions are mixed into the sauce, creating a sweet-savory balance. The pasta is tossed with the sauce, and a little pasta water is added for smoothness. Garnish with fresh parsley and extra Parmesan before serving for added flavor.

Ingredients:

For the Caramelized Onions:

  • 3 large onions (yellow or white), thinly sliced
  • 2 tbsp olive oil or butter
  • 1 tsp sugar (optional, to enhance sweetness)
  • tsp salt
  • 1 tbsp balsamic vinegar (optional, for added depth of flavor)

For the Pasta:

  • 400g pasta (such as fettuccine, spaghetti, or penne)
  • Salt (for pasta water)

For the Creamy Sauce:

  • 1 cup heavy cream (or half-and-half for a lighter version)
  • cup Parmesan cheese (freshly grated)
  • 1 tsp garlic powder or 2-3 cloves fresh garlic (minced)
  • 1 tsp dried thyme or fresh thyme (optional)
  • 1 tsp black pepper
  • 2 tbsp butter
  • cup pasta water (reserved from cooking the pasta)

Garnish (Optional):

  • Fresh parsley, chopped
  • Extra Parmesan cheese for serving
  • Red pepper flakes (for a little heat)

Step By Step Instructions:

1. Caramelize the Onions:

  • Preparation: Peel and thinly slice the onions. Aim for even slices to ensure uniform caramelization.
  • Cook the Onions: Heat 2 tbsp of olive oil or butter in a large skillet over medium-low heat.
  • Add the sliced onions and tsp of salt to the skillet. Stir to coat the onions with oil or butter.
  • Cook the onions on low to medium-low heat, stirring occasionally, for 30 to 40 minutes. The key is slow cooking to draw out the natural sugars, allowing the onions to gradually turn a deep golden brown.
  • Optional: Add 1 tsp of sugar after 15 minutes to help enhance the caramelization.
  • Optional for depth: In the last 5 minutes of cooking, add 1 tbsp of balsamic vinegar to the onions for an extra layer of flavor.
  • Set the caramelized onions aside once they're perfectly golden, soft, and slightly sticky.

2. Cook the Pasta:

  • Boil the Pasta: While the onions are caramelizing, bring a large pot of salted water to a boil.
  • Add 400g of your chosen pasta (fettuccine, spaghetti, penne) and cook according to the package instructions until al dente. This usually takes about 8-10 minutes.
  • Reserve cup of pasta water before draining the pasta. This starchy water will help bind the sauce later.
  • Drain the pasta and set it aside.

3. Prepare the Creamy Sauce:

  • Start the Sauce: In a separate large skillet or saucepan, melt 2 tbsp of butter over medium heat.
  • Add Garlic: If you're using fresh garlic, add 2-3 cloves of minced garlic and saut for 1 minute until fragrant. If using garlic powder, add it later with the cream.
  • Add the Cream: Pour in 1 cup of heavy cream and bring it to a gentle simmer, stirring occasionally. Lower the heat to avoid burning the cream.
  • Season: Add 1 tsp of garlic powder (if not using fresh), 1 tsp of dried thyme (or fresh thyme leaves), black pepper, and a pinch of salt to taste.
  • Add Parmesan: Stir in cup of freshly grated Parmesan cheese. Continue stirring until the cheese melts and the sauce becomes thick and creamy.

4. Combine the Elements:

  • Add the Onions: Add the caramelized onions to the creamy sauce and stir to combine. Allow the onions to infuse the sauce with their sweet, savory flavor.
  • Adjust Consistency: If the sauce feels too thick, add a little of the reserved pasta water (start with 1-2 tbsp) to loosen it. The starchy water helps make the sauce cling to the pasta.
  • Add the Pasta: Toss the drained pasta into the sauce. Stir everything together so that the pasta is evenly coated with the creamy onion sauce.

5. Final Touches:

  • Taste the pasta and adjust seasoning if needed. You may want to add more black pepper, salt, or Parmesan depending on your preference.
  • For an added kick, sprinkle some red pepper flakes if desired.

6. Garnish and Serve:

  • Garnish: Top with freshly chopped parsley for color and freshness.
  • Extra Parmesan: Serve with extra grated Parmesan on the side.
  • Optional: A drizzle of olive oil or a sprinkle of fresh thyme leaves adds a burst of flavor before serving.

Tips for Perfect Creamy Caramelized Onion Pasta:

  • Patience with Caramelizing: Caramelizing onions takes time. Don't rush the process by turning up the heat. Low and slow ensures sweet, perfectly golden onions.
  • Control the Creaminess: If you prefer a lighter dish, you can use half-and-half or milk instead of heavy cream. Just be sure to simmer gently to avoid curdling.
  • Balance Flavors: The sweetness of the caramelized onions balances well with the savory Parmesan and creamy sauce. If you prefer a sharper flavor, consider adding a splash of white wine to the sauce before adding the cream.
  • Texture Control: For a heartier texture, add saut ed mushrooms or spinach to the dish.

Serving Suggestions:

This creamy caramelized onion pasta pairs wonderfully with:

  • Garlic bread or crusty baguette for soaking up the sauce.
  • A light green salad with vinaigrette to balance the richness.
  • A side of roasted vegetables such as asparagus or broccoli for added nutrition.

Storage and Reheating:

  • Storage: Leftover pasta can be stored in an airtight container in the fridge for up to 3 days.
  • Reheating: To reheat, add a splash of milk or cream to the pasta while warming it in a skillet over low heat to revive the creamy texture.
