How to Make French Onion and Browned Butter Pasta
-
Sauté Onions: In a large non-stick skillet over medium-high heat, melt the ¼ cup of unsalted butter. Add your thinly sliced yellow onions and sauté for 25-30 minutes. Stir occasionally until the onions turn velvety soft and a deep caramel color. Season with salt and pepper, then transfer to a plate.
-
Brown the Butter: In the same skillet, melt the ½ cup of unsalted butter over medium-high heat. Keep stirring constantly; you want to scrape up any bits from the pan. Remove from heat as soon as the butter turns a rich chestnut brown and gives off a nutty aroma, then let it cool slightly.
-
Cook the Pasta: Bring a large pot of salted water to a rapid boil. Add the linguine and cook until al dente, about 8-10 minutes. Make sure to reserve 1 cup of pasta water before draining!
-
Blend the Sauce: In a powerful food processor or blender, combine the caramelized onions, browned butter, and ½ cup of the reserved pasta water. Blend until you achieve a smooth, well-combined mixture.
-
Heat the Sauce: Return the skillet to medium heat, then add the blended onion mixture, heavy cream, and parmesan cheese. Stir continuously until the cheese is melted and the sauce is warmed through.
-
Combine with Pasta: Toss the cooked linguine into the skillet and gently mix until the noodles are thoroughly coated with the creamy sauce. If you prefer a looser sauce, gradually add more reserved pasta water until you reach your desired consistency.
-
Serve and Garnish: Dish out the pasta hot, garnishing with additional parmesan cheese and a sprinkle of fresh parsley for that perfect touch of color and flavor.
Optional: Add a drizzle of olive oil on top for extra richness.
