How to make Guinness French onion soup recipe?
- Preheat oven: First, heat oven or broiler to 500 degrees F.
- Melt: Meanwhile, melt the butter in a large skillet or large pot over medium heat. Add the olive oil and onion cooking thoroughly until they are caramelized and brown. This usually takes about one hour, stirring every 10 to 15 minutes.
- Deglaze: Then, add beer or water to deglaze the pan to prevent burning.
- Add: Next, add the thyme, brown sugar, and garlic and cook on medium-high heat for about one minute.
- Thicken: After, on low heat, add the other half of the butter and flour and let it cook for about three or four minutes.
- Boil: Then, immediately add the beer, bay leaves, mustard, Worcestershire sauce, and the broth. Boil for 30 minutes.
- Serve: Ladle soup into heat-resistant bowls on a baking sheet, place cheese and bread on top of the soup until the cheese melts. This usually takes about one to three minutes.
Recipe variations:
- Slow cooker: For a later meal, toss the ingredients into your crock pot and cook it for three to four hours on high or six to eight hours on low.
- Other cheese: You could also use Gruyere cheese or whatever flavor you like best.
- Vegetable stock: If you do not have broth, vegetable or beef stock will do just fine.
- Soy sauce: Use soy sauce instead of Worcestershire sauce for a different flavor.
- Vinegar: Similarly, you can also use red wine vinegar instead of Worcestershire sauce.
- Chicken: Chicken broth will do in a pinch.
- Irish cheddar cheese: For an Irish twist, use Irish cheese.
How to serve:
This is a great dish for St. Patrick’s Day or any day of the year. The beer drinker of the family will love the addition of beer because it gives it a depth of flavor you cannot get otherwise. Here are some unique serving ideas you may enjoy:

Frequently asked questions
What is the best alcohol to use in French onion soup?
Although this recipe calls for Guinness beer because it is a special soup, most people use dry sherry, vermouth, red wine, or brandy in their classic French onion soup.
Then others use champagne or cognac. It depends on your taste and the recipe.
Which onions are best for this soup?
Because caramelized onions are the most important ingredient in this soup, you should use a fresh quality onion with the best flavor.
Although you should typically go with what the French onion soup recipe calls for, you also have to go by your own tastes.
Most recipes call for red or yellow onions, but you can also use white or Vidalia as well.
What is the difference between this and regular onion soup?
The end result in both of these soups are almost the same but the ingredients are a bit different. For example, French onion uses just one kind of onion, but English onion uses several kinds including shallots.
Also, English onion soup uses Worcestershire sauce instead of liquor. Lastly, French onion typically calls for Swiss cheese and English uses cheddar.
How to store leftovers:
- Store: After the soup is cooled to room temperature, you can store it in your fridge in an airtight container for up to five days.
- Freeze: To freeze, put soup into a freezer bag and lay it flat. It will stay fresh for up to 90 days.
- Thaw: Thaw overnight in the fridge before serving for best results.
- Reheat: Put soup in a microwave-safe bowl and reheat in the microwave for one or two minutes, depending on how much you are heating. Or put it into a saucepan on low heat until it boils.

Cooking tips:
- Make sure you stir broth often as it boils to keep the onions from sticking to the bottom.
- While deglazing, be sure you are scraping the bottom to get the glazed onions off.
- Try to place onions in a single layer to help them glaze more evenly.
- You can use a Dutch oven instead of a large saucepan.
- Preheat the broiler and place the bread on the top oven rack to broil to make it crusty.
- Be sure you use oven-proof bowls when you put them in the oven.
- You can also use individual broiler-safe crocks.
- Cut onion slices thick for a more intense onion flavor.
