Step-by-Step Instructions

Step 1: Caramelize the Onions

1. Heat butter and olive oil in a large pot over medium-low heat.
2. Add onions, sugar, salt, and pepper. Stir occasionally for 20–25 minutes until golden brown and caramelized.
3. Add garlic and thyme during the last 2 minutes of cooking.

Step 2: Deglaze the Pot

• Pour in white wine (if using) and scrape up any brown bits. Simmer until wine reduces by half.

Step 3: Cook the Pasta

• Pour in beef broth and bring to a boil.
• Add pasta and cook according to package instructions, stirring often to prevent sticking.

Step 4: Make It Creamy

• Once pasta is al dente, reduce heat to low.
• Stir in heavy cream, Gruyère, and Parmesan until melted and creamy.

Step 5: Serve

• Garnish with fresh parsley and extra cheese.
• Serve immediately while hot and cheesy.

Tips for Success

• Slice onions evenly so they caramelize at the same rate.
• Stir onions occasionally, but don’t over-stir—letting them sit helps caramelization.
• For richer flavor, use beef broth. For lighter flavor, go with vegetable broth.
• Reserve a splash of pasta water in case you need to loosen the sauce.

Common Mistakes to Avoid

• Rushing the onions: Caramelization is key. Don’t cook on high heat or you’ll burn them.
• Too much liquid: Measure broth carefully; too much can make pasta watery.
• Not stirring pasta: Since it’s cooked in broth, pasta may stick—keep it moving.
• Overcooking pasta: Stop when al dente, as it will continue cooking slightly in sauce.

Storing Tips

• Refrigerator: Store leftovers in an airtight container up to 4 days.
• Freezer: Not recommended, as creamy sauces may separate.
• Reheat: Warm gently on the stove with a splash of broth or cream to restore creaminess.
