Too Much Cheese – While cheese adds flavor, overloading the dough can make it greasy and soggy.
Watery Veggies – Toppings like tomatoes or mushrooms release excess moisture, which can result in a soggy, undercooked focaccia.
Too Many Herbs – Fresh herbs are great, but overloading with them can overpower the bread's natural flavor and make it too earthy.
Heavy Sauces – Creamy or oily sauces, like Alfredo, can weigh down the dough, making it too dense and greasy.
Sweet Toppings – Avoid overly sweet toppings like fruit or sugary sauces, as they clash with the savory nature of focaccia.
Spicy Ingredients – Strong, spicy toppings like jalapeños can overpower the mild flavor of focaccia unless used in moderation.
Excessive Salt – Focaccia is already salted, so avoid adding too much salt or salty ingredients like olives or anchovies, which can make the bread too salty.
