Ingredients
- 2 large onions (thinly sliced)
- 3 tablespoons olive oil
- 1 tablespoon butter
- 1 teaspoon sugar
- 1/2 teaspoon salt
- 3 cloves garlic (minced)
- 1/2 cup white wine (optional)
- 1/2 cup vegetable or chicken broth

How to Make Caramelized Onion Pasta
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Cook the pasta according to the package instructions until al dente. Drain and set aside.
Step 2: Caramelize the Onions
In a large skillet, heat the olive oil and butter over medium heat. Add the sliced onions, sugar, and salt. Cook, stirring occasionally, for about 25–30 minutes until the onions are golden brown and caramelized. Be patient and avoid burning them; lower the heat if necessary.
Step 3: Add Garlic
Add the minced garlic to the skillet. Cook for another 1–2 minutes until fragrant.
Step 4: Deglaze the Pan
If using white wine, pour it into the skillet to deglaze. Scrape up any browned bits from the bottom. Let it simmer for a few minutes until mostly evaporated.
Step 5: Add Broth and Cream
Pour in vegetable or chicken broth along with heavy cream. Stir to combine and let it simmer for about 5 minutes until the sauce thickens slightly.
Step 6: Add Cheese
Stir in grated Parmesan cheese until melted and well incorporated into the sauce. Season with salt and pepper to taste.
Step 7: Combine Pasta and Sauce
Add the cooked pasta to the skillet. Toss to coat evenly with the sauce.
Step 8: Serve
Divide the pasta among serving plates. Garnish with chopped fresh parsley and additional Parmesan cheese if desired. Enjoy your delicious caramelized onion pasta!

How to Perfect Caramelized Onion Pasta

- Deglaze the Pan: Adding white wine after caramelizing lifts flavorful bits stuck to the skillet, enhancing your sauce.

- Reserve Pasta Water: Save a cup of pasta water before draining; it can help adjust sauce consistency if needed.
