What makes this recipe ideal for beginners? First and foremost, it’s a one-pot meal. That means minimal clean-up and no need to juggle multiple pans or techniques.

Ingredients and Preparation

To make One Pot French Onion Pasta, you’ll need the following ingredients:

• 2 tablespoons unsalted butter
• 2 tablespoons olive oil
• 3 large yellow onions, thinly sliced
• 4 cloves garlic, minced
• 1 tablespoon fresh thyme leaves
• 1/4 cup dry white wine (optional, but it adds depth of flavor)
• 5 cups low-sodium beef broth (for a vegetarian option, use vegetable broth)
• 1 tablespoon Worcestershire sauce
• 12 ounces uncooked rigatoni or other short pasta (penne or fusilli are great substitutes)
• 1 cup shredded Gruyère cheese (or swap with mozzarella or Parmesan)
• 1/4 cup heavy cream
• Salt and freshly ground black pepper, to taste
• Fresh parsley, chopped, for garnish

Ingredient Alternatives:

• If you prefer a different cheese, mozzarella or Parmesan can easily replace Gruyère.
• For a vegetarian version, simply use vegetable broth instead of beef broth, and skip the Worcestershire sauce.
• You can opt for different pasta shapes depending on what you have on hand, but short pasta like rigatoni or penne works best since it absorbs the broth.

Step-by-Step Instructions

1. Caramelize the Onions:
   • In a large pot, melt the butter and olive oil over medium heat. Add the sliced onions and stir frequently. Caramelizing onions is a slow process that takes time but is well worth it. You’ll want to cook them for about 20–25 minutes, until they are deeply golden and soft. This slow cooking process brings out the natural sweetness in the onions and gives the dish its signature flavor.
   • Tip: If the onions start to brown too quickly or burn, lower the heat slightly and add a splash of water to help them soften.
2. Deglaze the Pot:
   • Once the onions are nicely caramelized, it’s time to deglaze the pot. Add a splash of the beef broth (or wine, if you’re using it) and scrape up any browned bits from the bottom of the pot. This step ensures you capture all the flavorful bits that may have stuck to the bottom during cooking.
3. Add the Broth and Pasta:
   • Pour in the remaining beef broth and bring the mixture to a boil. Once boiling, add the uncooked pasta. Reduce the heat to a simmer and cook the pasta for about 10–12 minutes, or until it’s al dente and most of the liquid has been absorbed. Stir occasionally to prevent the pasta from sticking.
   • Tip: If the pasta absorbs too much liquid before it’s fully cooked, add a little more broth or water.
4. Incorporate the Cheese:
   • Once the pasta is cooked, stir in the shredded Gruyère cheese and heavy cream. Continue stirring until the cheese melts into the pasta, creating a creamy, luscious sauce.
   • Tip: If you like a more indulgent dish, feel free to add extra cheese! Just be sure to taste and adjust the seasoning with salt and pepper as needed.
5. Garnish and Serve:
   • For a burst of color and freshness, garnish the pasta with freshly chopped parsley or thyme. Serve immediately while hot and enjoy the comforting flavors of this hearty dish.

Beginner Tips and Notes

• Troubleshooting:
  • Onions are cooking too quickly or burning: Lower the heat and add a small amount of water to help them soften.
  • Pasta sticks together: Stir the pasta occasionally while it cooks to keep it from clumping together.
  • Too much liquid: If there’s excess liquid left at the end of cooking, increase the heat to reduce the sauce or stir in more cheese to thicken it up.
• Kitchen Tips:
  • Prepping the onions: Slice your onions evenly for consistent caramelization. A sharp knife makes the process easier.
  • Shredding cheese: Freshly shredded cheese melts better than pre-shredded cheese, which often contains anti-caking agents.
  • Efficient pasta cooking: To save time, measure your pasta and have all your ingredients ready to go before you start cooking (this is called “mise en place”).

Serving Suggestions

To make this meal even more satisfying, consider pairing it with a side of crusty bread or a light salad. The richness of the pasta is balanced nicely by the freshness of a simple green salad with a tangy vinaigrette. If you have extra cheese, sprinkle some on top of the bread for a makeshift cheesy garlic bread.

For a more complete meal, serve the pasta alongside roasted vegetables like Brussels sprouts, carrots, or green beans. A drizzle of balsamic glaze can elevate the dish further and bring out the natural sweetness of the caramelized onions.

Storage and Leftovers

If you have leftovers, store the pasta in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop, adding a splash of broth or water to loosen the sauce as needed. The pasta may absorb some of the sauce while sitting, but with a little extra liquid, it’ll be just as creamy and delicious as the first time you served it.
