One-Pot French Onion Pasta

Ingredients

• 2 large Onion (peeled and sliced thin)
• 2 tablespoons Unsalted Butter (cut into pieces)
• 1 teaspoon Granulated Sugar
• 1 teaspoon Salt (plus more to taste)
• 1/2 cup Dry White Wine (any dry variety)
• 1 tablespoon Cherry Vinegar
• 12 ounces Dry Pasta (such as linguine or fettuccine)
• 4 cups Beef Broth (low‑sodium preferred)
• 1 tablespoon Worcestershire Sauce
• 1 teaspoon Dried Thyme
• 1/2 teaspoon Black Pepper (freshly ground)
• 1 cup Heavy Cream (cold)
• 1/2 cup Parmesan Cheese (freshly grated)

Instructions

1. Prepare the Onions

   Peel the onions, slice them thinly (about 1/8 inch). If you have extra onions, place the sliced pieces in a zip‑top bag and freeze for later broth use.

   Time: PT5M

2. Caramelize the Onions

   Melt the butter in the large pot over medium heat. Add the sliced onions, 1 tsp sugar, and 1 tsp salt. Stir frequently and cook until the onions turn a deep golden‑brown, about 10 minutes. Adjust heat if they start to brown too quickly.

   Time: PT10M

3. Deglaze

   Pour in the 1/2 cup white wine and 1 tbsp cherry vinegar. Scrape the browned bits from the bottom of the pot with a wooden spoon. Let the liquid reduce for about 2 minutes.

   Time: PT2M

4. Add Pasta and Broth

   Stir in the dry pasta, then pour in 4 cups beef broth. Add 1 tbsp Worcestershire sauce, 1 tsp dried thyme, and a pinch of black pepper. Season with additional salt if needed.

   Time: PT1M

5. Simmer

   Cover the pot, reduce heat to low, and let the mixture simmer for 10‑12 minutes, or until most of the liquid is absorbed and the pasta is al dente. Stir once halfway through.

   Time: PT12M

6. Finish with Cream and Cheese

   Remove the pot from heat. Stir in 1 cup cold heavy cream and the grated Parmesan until the sauce becomes glossy and coats the pasta. Adjust seasoning with salt and pepper, then serve immediately.

   Time: PT3M

Troubleshooting

Storage

Refrigerator: Store leftovers in an airtight container for up to 3 days. Reheat gently on the stovetop, adding a splash of broth or milk if the sauce thickens.

Freezer: Not recommended due to the cream and cheese; texture may separate.

Room temperature: Do not leave at room temperature for more than 2 hours.

Make-Ahead Tips

• Slice and freeze onions in a zip‑top bag for future use.
• Caramelized onions can be made up to 2 days ahead and stored in the fridge.
• Prepare the broth and measure all liquids before starting the cooking process.
