Whether you’re cooking for a cozy night in or impressing guests with a surprisingly simple dinner, French Onion Pasta delivers depth of flavor and a sense of warmth that will leave everyone asking for seconds.

Why This Recipe Works

• Caramelized onions: Slowly cooked onions provide a deep, rich flavor that’s both sweet and savory.
• Cheese: Gruyère or Swiss cheese melts beautifully, echoing the classic French onion soup topping.
• Cream or broth: Creates a luxurious sauce that clings to every strand of pasta.
• Pasta: Any long pasta like fettuccine, linguine, or spaghetti works, providing a satisfying vehicle for the sauce.

By balancing sweetness, umami, and creaminess, this dish becomes an instant comfort classic.

Ingredients

• 12 oz pasta (fettuccine, linguine, or spaghetti)
• 3 tablespoons unsalted butter
• 2 tablespoons olive oil
• 3 large onions, thinly sliced
• 2 cloves garlic, minced
• 1 teaspoon sugar (optional, for quicker caramelization)
• 1/4 teaspoon salt
• 1/4 teaspoon black pepper
• 1/2 teaspoon fresh thyme leaves (or 1/4 tsp dried thyme)
• 1/2 cup dry white wine (optional)
• 1 1/2 cups beef or vegetable broth
• 1/2 cup heavy cream
• 1 cup shredded Gruyère or Swiss cheese
• 1/4 cup grated Parmesan cheese
• Fresh parsley for garnish

Instructions

1. Cook pasta according to package directions until al dente. Reserve 1/2 cup pasta water and drain the rest. Set aside.
2. In a large skillet, heat butter and olive oil over medium heat. Add sliced onions and stir to coat.
3. Cook onions slowly, stirring frequently, until deep golden brown and caramelized, about 25–30 minutes. Add sugar halfway through if desired.
4. Add minced garlic and thyme; cook 1–2 minutes until fragrant.
5. Deglaze the pan with white wine if using, scraping up any brown bits from the bottom. Let it reduce slightly.
6. Pour in broth and bring to a simmer. Let simmer 5–7 minutes for flavors to meld.
7. Stir in heavy cream and half of the Gruyère cheese. Mix until melted and smooth.
8. Add cooked pasta to the sauce, tossing to coat evenly. Use reserved pasta water to thin sauce if needed.
9. Sprinkle remaining Gruyère and Parmesan over pasta and stir gently to combine.
10. Season with additional salt and pepper to taste.
11. Serve hot, garnished with fresh parsley and extra cheese if desired.

Tips for Perfect French Onion Pasta

• Patience with onions: Slow caramelization is key for deep flavor.
• Cheese choice: Gruyère melts beautifully; Swiss or mild cheddar are good alternatives.
• Wine: Optional, but adds a subtle acidity that brightens the sauce.
• Consistency: Use reserved pasta water to achieve the perfect creamy consistency without thinning the flavor.
• Make ahead: Caramelize onions in advance; store in fridge for up to 3 days, assemble and reheat before serving.

Serving Suggestions

• Serve with a side of garlic bread or crusty baguette.
• Pair with a light green salad for balance.
• Top with crispy fried onions for extra texture and authenticity.
• Perfect for weeknight dinners, romantic evenings, or casual entertaining.
