To get the most out of your pizza-eating experience, it is essential to understand the science of pizza: what causes pizza to be greasy or taste different, how to prevent it, and what to do if you have left pizza out at room temperature overnight.

But beyond being delicious, pizza is a complex food, which can be affected by numerous factors.

Pizza is beloved for its wide variety of flavors, textures, and styles. Whether you’re indulging in a bubbly and oozing cheese classic from an iconic pizzeria, or pulling out a slice of homemade sauce-and-cheese pie from your oven, pizza is an undeniably delicious way to enjoy a meal.

What Causes Pizza To Be Greasy or Taste Different

There are various factors that can affect a pizza’s texture, flavor, and overall quality. The most influential factor is the cooking method, as this affects the crust, which is the foundation upon which all other ingredients must work together to create a great pie.

However, there are many other elements that can affect a pizza’s outcome as well. Here are some of the most important factors to consider when making pizza:


Flour: Different types of flour absorb moisture differently, which can affect the pizza crust’s texture. Generally speaking, bread flour contains more gluten, which helps the crust to become crispy and gives it a chewy texture. All-purpose flour is more versatile, but the texture of the crust may not be as firm or crispy.


Toppings: Your choice of toppings can affect both the taste and the texture of the pizza. Cheese, for instance, can create a greasy coating on the surface of the pizza when heated, and certain vegetables, such as peppers, cook quicker and release more moisture as they cook.


Sauce: The quality of your sauce can have a big impact on the flavor of your pizza. Make sure to use only high-quality tomato sauce, as well as other ingredients that will bring out the full flavor of the pizza.

Oven Temperature

Oven temperature: The temperature of the oven is another key factor when it comes to making a delicious pizza. Too low of a temperature can cause the pizza to become too doughy and not cook though, while too high of a temperature can cause the pizza to burn.

How to Prevent Greasy Pizza

Greasy pizza can ruin an otherwise stellar eating experience. Fortunately, there are a few things you can do to ensure a crisp, delicious pie every time. Here are a few tips for preventing a greasy pizza:

Fresh Ingredients and Topping Tactics

Use fresh ingredients: Make sure you are using fresh cheeses, vegetables, and other toppings for your pizza. Old, expired cheese or expired canned vegetables will release more grease and moisture, which can make your pizza greasy.

Blot the toppings: if you are using fresh veggies or proteins, make sure to pat them dry with a paper towel before you put them on the pizza. This will help to absorb some of the moisture and prevent the pizza from becoming greasy.

Use a lower oven temperature: cooking the pizza at a lower temperature will prevent the grease from the cheese and toppings from melting too quickly and making the pizza greasy.

What to Do If You Have Left Pizza Out at Room Temperature Overnight

If you have left your pizza out at room temperature overnight, it is important to take action as quickly as possible. The first thing to do is inspect the pizza for any signs of spoilage, such as mold, discoloration, or a foul smell.

If the pizza looks moldy or otherwise inedible, it is best to discard it immediately. If the pizza looks normal but is lukewarm, it is best to reheat it in the oven or microwave until it reaches an internal temperature of 165°F before eating.

Different Pizza Styles and Toppings Affect Taste

There are countless ways to enjoy a slice of pizza, and each offers unique pros and cons. Here are the pros and cons of some popular pizza types and toppings:

  • Neapolitan Pizza: Popularized in Naples, Italy, the Neapolitan features a thin, soft crust, and a minimal amount of tomato sauce and cheese. Pros: Light and simple. Cons: May be too light and simple for some.
