French Onion Pasta One Pot

Transforming the beloved French onion soup into a hearty pasta dish creates pure comfort in a bowl. This one-pot French onion pasta marries sweet, deeply caramelized onions with al dente mezze rigatoni, all enveloped in a rich, Gruyere-laced sauce that captures the essence of the classic French soup.

After making this recipe countless times, I've found it's the perfect dish for those chilly evenings when you want something special but don't want to spend hours managing multiple pots and pans. My family actually prefers this to traditional French onion soup now - they love how the pasta soaks up all those amazing flavors.

Essential Ingredients and Selection Tips

• Yellow Onions: Choose firm, heavy onions with shiny, paper-thin skins. The natural sugars in yellow onions make them perfect for caramelizing.
• Mezze Rigatoni: This shorter pasta variant has the perfect ridges to catch the sauce. Look for bronze-die cut pasta for the best sauce adherence.
• Gruyere Cheese: Splurge on aged Gruyere - its nutty, complex flavor is essential. Make sure to grate it fresh.
• Beef Bone Broth: The collagen-rich broth creates a silky sauce. Choose one with a deep brown color and rich aroma.
• Sherry and White Wine: These aren't just fancy additions - they help deglaze the pot and add crucial depth. Choose dry varieties you'd enjoy drinking.

Detailed Cooking Instructions

1. Starting the Onion Magic:

- Slice your onions with the grain (from root to stem) about 1/8 inch thick. This helps them hold shape during long cooking.
- Heat avocado oil in a heavy-bottomed Dutch oven until it shimmers.
- Add onions, salt, and water - the water helps them soften evenly before caramelizing.

2. Perfecting the Caramelization:

- Once initial moisture evaporates, maintain medium-low heat - too hot and they'll burn.
- Stir every 5-7 minutes, scraping thoroughly. Look for gradual color changes from white to blonde to amber.
- You'll notice the onions reducing significantly in volume - this concentration equals flavor.
- When they reach a deep golden brown, deglaze with sherry and wine.

3. Building the Pasta Component:

- Add pasta and liquids to the same pot - the starch release will help thicken your sauce.
- Keep an eye on liquid levels, stirring frequently to prevent sticking.
- Test pasta regularly - you want it just slightly firmer than al dente.

4. Creating the Final Symphony:

- Lower heat before adding cheese to prevent graininess.
- Stir in half & half gradually, assessing consistency as you go.
- Let everything meld together for 2-3 minutes before serving.
