Instructions
Prepping
- Slice the mushrooms, grate the cheese and prepare the stock.225 grams (½ lb) mushrooms, 85 grams (3 oz) Gruyere cheese, grated, 700 millilitre (3 US cups) chicken stock
- Take the sprigs of thyme and tie them together using a piece of string. Set aside.4 sprigs thyme
- Slice the onions into rings or half rings using a kitchen mandoline or a sharp knife. Aim for a thickness of approximately 3-4mm (0.2"). No need to be perfect.3 large (minimum 450g/1 lb) onions, sliced
Making the pasta
- Melt the butter over medium heat. Add the sliced onions and salt. Cover with a lid and let it cook for 5 minutes. After this time, take off the lid and give the onions a good stir.2 tablespoons butter, heaped, ½ teaspoon salt
- Continue cooking the onions, uncovered, over low heat for an additional 25 minutes until they turn a deep, golden brown colour. Stir the onions every 2-3 minutes, making sure to scrape the bottom of the pot as you do so. If the onions begin to stick, add a small splash of water as necessary. However, try to avoid adding water until the last 10 minutes of cooking.
- Next, add the sliced mushrooms, chopped garlic, bunch of thyme and black pepper to the pot. Sauté the mixture over low heat for 3-4 minutes until the mushrooms begin to shrink slightly.2 teaspoons garlic, chopped, ¼ teaspoon black pepper
- Add the sherry. Deglaze the pan by scraping off any bits stuck to the bottom. This adds extra flavour to the dish.4 tablespoons sherry
- Pour in the chicken stock, add the dry pasta and sherry vinegar. Stir the mixture and bring it to a gentle simmer. Securely place the lid on the pot and cook over low heat for 18-20 minutes until the pasta is al dente. Stir every 2-3 minutes. Keep it brief to avoid losing too much steam.225 grams (½ lb) dry rigatoni pasta, 1 tablespoon sherry vinegar
- Typically, there's no need to add more liquid when cooking with the lid on. However, trust your instincts and if absolutely necessary, add a small splash of extra stock or water.
- Take the pan off the heat and remove the bunch of thyme.
- Stir in the grated cheese and cream. If the cheese isn't melting as desired, briefly return the pan to low heat for a minute while gently folding the cheese through the pasta.6 tablespoons double cream (heavy cream)
- Test for seasoning and add more if needed.
- Plate up and serve with additional cheese on top and a sprinkle of chopped thyme.
Notes
Please read:
Numerous French onion pasta recipes can be found online, yet a prevalent issue echoed in user feedback for these recipes revolves around two key points:
- Many express concern that the specified amount of stock in the recipe they chose is insufficient for properly cooking the pasta.
- Another recurring feedback is that the suggested time frame often falls short, leaving the pasta undercooked.
Use the right pot
Opt for a large, heavy-based, lidded saucepan such as a Dutch oven or a cast iron casserole dish. This type of pot is ideal as it offers a generous surface area for the proper caramelisation of onions and ensures even heat distribution throughout the cooking time.Cover the pot tightly once the pasta is added
Once you've added the pasta, tightly cover the pot. This helps trap the steam, preventing excessive liquid loss during the pasta cooking process. Make sure the lid forms a tight seal and doesn't have any openings, such as a small steam hole, to retain the steam effectively.Cook over low heat
When it starts simmering, turn the heat down to the lowest setting. Keep it low throughout the cooking time. The blazing hot steam trapped inside the pot is enough to cook the pasta.Stir frequently
Remember to stir the pasta every 2-3 minutes or so throughout the 20-minute cooking time. This helps ensure it doesn't stick to the bottom and rotating the pieces ensures even cooking. Keep it brief to avoid losing too much steam.Only add liquid if needed
Trust the process and only add extra liquid if absolutely necessary. If you follow the guidelines and use the recommended amount of stock, you shouldn't need to add more during the 20 minutes of cooking. Even if some pieces of pasta aren't fully submerged, the steam trapped under the lid will help cook them, along with frequent stirring.Use your noggin
If you're using a pot with a thinner base, a poorly sealing lid or a stove that's too hot even on low heat, think on your feet and use your judgement. Consider adding a bit more liquid, shifting to a smaller burner or placing something heavy on the lid to secure it better. Adapt as needed for your cooking setup.
