One Pot French Onion Pasta Ingredients
For the Pasta

For the Onions
• Yellow onions – Slice into 1/8-inch rings; essential for caramelization that creates a sweet and rich base.
For Flavoring
• Garlic – 4 cloves, minced; this deepens the flavor profile beautifully—reduce for a milder taste or swap for garlic powder.
• Worcestershire sauce – A splash enhances umami; you can substitute with vegetarian Worcestershire sauce if desired.
• Soy sauce – Adds a touch of saltiness and depth; reduced sodium options allow for better seasoning control.

For the Broth
• Water + beef bouillon – Create a savory broth base; swap for vegetable broth for a vegetarian version.
For the Creaminess
