Tasty French Onion Pasta

Mixing the classic French onion soup with pasta creates the ultimate comfort food experience. This one-pot onion pasta combines sweet, slowly browned onions with perfectly cooked mezze rigatoni, all wrapped in a delicious Gruyere-infused sauce that brings to mind the familiar taste of France's famous soup.

I've made this dish so many times now, and it's just right for those cold nights when you want something special without juggling tons of pots and pans. My kids now ask for this instead of the traditional soup version - they love how the pasta soaks up all the tasty flavors.

Key Ingredients and Shopping Advice

• Yellow Onions: Go for ones that feel heavy and have tight, shiny skins. Yellow onions naturally contain more sugars, making them ideal for browning.
• Mezze Rigatoni: This compact pasta shape has grooves that trap the sauce perfectly. Try to find pasta made with bronze dies for better sauce coating.
• Gruyere Cheese: Worth paying extra for aged Gruyere with its rich, nutty taste that's key to this dish. Always grate it yourself right before using.
• Beef Bone Broth: Pick one that's thick with collagen for a smooth sauce. Look for deep color and strong smell.
• Sherry and White Wine: These aren't just fancy extras - they scrape up the tasty bits from the pot bottom and add important flavor. Pick dry ones you'd happily drink.

Step-by-Step Cooking Guide

1. Starting the Onion Magic:

- Cut onions from end to end about 1/8 inch thick so they keep their shape while cooking.
- Warm avocado oil in a heavy Dutch oven until it's glossy.
- Toss in onions with salt and water to help them soften evenly at first.

2. Perfecting the Caramelization:

- After the water cooks off, keep heat at medium-low so they don't burn.
- Give them a stir every 5-7 minutes, making sure to scrape the bottom well. Watch as they change from white to light gold to amber.
- You'll see them shrink down a lot - that means flavor is concentrating.
- When they turn deep gold, pour in sherry and wine to loosen all the tasty bits.

3. Building the Pasta Component:

- Add pasta and liquids right to the same pot - the starch will naturally thicken your sauce.
- Watch the liquid level and stir often so nothing sticks.
- Check pasta regularly - you want it just a tiny bit firmer than perfectly done.

4. Creating the Final Symphony:

- Turn down the heat before adding cheese so it melts smoothly without clumping.
- Pour in half & half slowly, checking thickness as you go.
- Let everything sit together for 2-3 minutes before serving.

I grew up in a home with lots of French cooking influence, and I've always loved how onions change when you cook them slowly. The sweet, deep flavor they develop is just amazing - that's why I use them so much in my cooking.

Getting It Just Right

• For extra luxury, throw in some butter when adding the half & half.
• Make sure to scrape up all the brown bits when deglazing - that's where tons of flavor hides.
• Add some fresh thyme right before you serve to give the whole dish a lift.

I'm still wowed by how these basic ingredients turn into something so fancy-tasting, even after making this countless times. The secret really is taking your time with those onions - they're what makes this dish special.
