🧅 What Makes French Onion Pasta Special?

Traditional French Onion Soup builds flavor by slowly caramelizing onions until they release their natural sugars and transform into melt-in-your-mouth goodness. This pasta uses the same technique — but instead of ladling soup into a bowl, you add pasta directly to the pot to simmer in the onion broth.

The pasta absorbs every drop of flavor while releasing starches that help thicken the sauce.
Then, nutty Gruyere cheese and a sprinkle of Parmesan melt in to create a silky finish.
The result: all the comfort of the iconic soup… but even more satisfying.

This dish is living proof that a handful of humble ingredients can produce something extraordinary.

📌 Key to Success: Low & Slow Caramelized Onions

Caramelizing onions takes time — don’t rush this step.
The browning (not burning!) is where all the flavor develops.

You’ll know they’re ready when:

• They’re soft and jammy

• They’ve turned a deep golden brown

• They smell sweet and savory at the same time

Pro Tip: If onions start sticking or browning too quickly, reduce heat and add a splash of water or extra butter to deglaze.
