Why This Recipe Works

Heavy cream and Gruyère cheese bring richness and a velvety texture, while fresh thyme adds a subtle herbal note. The medium pasta shells are the perfect vessel for catching the sauce, ensuring every bite is packed with flavor.

• 8 oz medium pasta shells: Perfect for holding the creamy sauce.
• 2 large onions, thinly sliced: The star of the dish, bringing sweetness and depth.
• 2 tbsp unsalted butter: Helps caramelize the onions.
• 1 tbsp olive oil: Prevents the butter from burning and adds richness.
• 1/2 tsp sugar: Speeds up the caramelization process.
• 2 cloves garlic, minced: Adds a savory, aromatic base to the sauce.
• 1/4 cup dry white wine (optional): Enhances the sauce with acidity and depth; substitute with broth if preferred.

How to Make Creamy Caramelized Onion Pasta

Follow these steps to create a dish that’s as indulgent as it is easy to make:

1. Cook the Pasta

Bring a large pot of salted water to a boil and cook the pasta shells according to package instructions until al dente. Drain and set aside. Cooking the pasta al dente ensures it holds its shape and doesn’t become mushy when mixed with the sauce.

2. Caramelize the Onions

In a large skillet, melt the butter with the olive oil over medium heat. Add the sliced onions and sprinkle with sugar to help them caramelize. Cook for 20-25 minutes, stirring occasionally, until the onions are golden brown and deeply caramelized.

3. Add Garlic and Deglaze

Stir in the minced garlic and cook for 1-2 minutes until fragrant. Pour in the white wine (if using) to deglaze the pan, scraping up any browned bits stuck to the bottom. Let the wine cook off for about 2 minutes.

4. Create the Sauce

Add the beef broth, heavy cream, and thyme to the skillet. Stir to combine and let the mixture simmer for 5-7 minutes, or until the sauce thickens slightly.

5. Combine Pasta and Cheese

Add the cooked pasta shells to the skillet, stirring to coat them in the sauce. Sprinkle in the Gruyère cheese and stir until melted and creamy. Season with salt and pepper to taste.

6. Garnish and Serve

Transfer the pasta to serving bowls and garnish with chopped parsley for a fresh, vibrant finish. Serve immediately with a slice of crusty baguette to soak up the sauce.

Tips for the Best Caramelized Onion Pasta

• Be Patient with the Onions: Caramelizing onions takes time, but the deep, sweet flavor is worth the effort. Cook them slowly over medium-low heat to prevent burning.
• Use Good Cheese: Gruyère or Swiss cheese melts beautifully and adds a nutty richness to the dish. Choose high-quality cheese for the best flavor.
• Customize the Protein: Add cooked chicken, crispy bacon, or sautéed mushrooms for a heartier meal.
• Season as You Go: Taste and adjust the seasoning throughout the cooking process for a perfectly balanced dish.

Serving Suggestions

This creamy caramelized onion pasta is a complete meal on its own, but it pairs wonderfully with simple sides:

• Crusty Bread: A baguette or focaccia is perfect for soaking up the rich sauce.
• Green Salad: A light, tangy salad balances the dish’s richness.
• Roasted Vegetables: Serve with roasted asparagus, zucchini, or Brussels sprouts for added nutrition.
