What kind of onion is best for French Onion Soup?
The best onions for caramelized onions are sweet, white onions. I haven’t tried this recipe with red onions but wouldn’t recommend it.
French Onion Soup Recipe Easy Substitution
Olive Oil: You can substitute avocado oil, butter, or ghee.
Fresh Thyme: If you don’t have fresh thyme, add ½ teaspoon of dry thyme.
Red Wine: Use a good quality red wine, something you would drink. If you don’t usually have red wine on hand, you can buy small single serve bottles at most convenience and grocery stores.Dry white wine can be used in place of red wine. Sauvignon Blanc or Chardonnay both work well for white wine. You can omit the wine altogether, or substitute it with sherry.
Broth:Anybrothor stock (broth and stock are the same) can be used in any soup recipe.Beef Broth,Chicken Broth, or vegetable broth all work interchangeably. I always use low or no salt broth.
Can I omit the flour? Yes! The flour mixes together with the olive oil from the caramelized onions to make a roux, which thickens the soup. If you skip the flour, your soup will just be a bit on the thin side. You can also use just 1 tablespoon of flour instead of two, again this will make a thinner soup but will not affect the flavor.
I don’t have oven proof bowls, what can I use? Place slices of bread on a baking sheet lined with foil, top with cheese and broil briefly until cheese is melted. Place the cheesy toast on top of the soup just before serving.
Lower Carb: You can also use a parmesan crisp for texture instead of bread. Simply melt a handful of freshly shredded parmesan cheese on a silicone baking mat in a 400℉ oven until golden brown, about 3 minutes. Watch it closely so it does not burn.
