Grandma Pizza

The Grandma pizza is my favorite pizza to make and once you see how easy it is, it will become yours as well.  Created at Umberto's of New Hyde Park in Nassau County, Long Island, this amazing pizza can now be found in most of the New York metro area.  Everything you've ever wanted to know about the technique and ingredients needed to create the perfect Grandma pizza is below. 

What is Grandma pizza?

Grandma pizza is unique and quite different from the ubiquitous traditional New York pizza.

It is a fairly thin sheet-pan pizza that's baked in a pan that has been heavily coated with olive oil.  This creates the perfect environment to fry the bottom of the pizza giving Grandma pizza that unmistakable crunch!

Grandma pizza contains sliced mozzarella cheese and randomly scattered thick plum tomatoes on top. 

Kind of like an upside-down pie.

It's almost always drizzled with a heavy dose of garlic-infused olive oil and finished with some Sicilian oregano and Pecorino Romano cheese.

Just talking about it makes me want to make one right now!

Where did Grandma pizza come from?

The Grandma pie was created on Long Island at Umberto's of New Hyde Park.  Its popularity soared in the 2000s and onward in the New York metro area. 

Fun fact:  Umberto's would often make special deliveries for the New York Giants and Yankees.  I'm sure the Mets and Jets like it too. 😉

Though the Grandma pie isn't quite as well known as a traditional New York pizza or a New York Sicilian, it's still very well known amongst New Yorkers.   

Some of the more popular places amongst the hipster crowd will create their own names for the style, but basically, it's a thin sheet pan pizza. 

Just like the one your Nonna would make.

How to make the dough

Each number corresponds to the numbered written steps below.

Note: Mass measurements will always be more accurate than volume measurements.  For doughs and bread, this is a good thing, because it provides absolute consistency.  I only use mass measurements for baking/dough recipes and always stick to standard cups, tablespoons, etc. when "cooking".  But, I also provide the volume (standard U.S. customary) measurements here and in the recipe card below.

Bakers Percentages: 64% hydration, .4% yeast, 2% salt, 3.4% oil, 1.2% sugar

Note:  Baker's percentages will allow you to scale the dough amount up or down depending on how much you need.  To use baker's percentages you simply divide the amount of flour in a recipe by 100 and then multiply that number by the percentages listed above.

1. Weigh out or measure 406 grams (3.25 cups) of bread flour, 2 grams (½ teaspoon) of instant yeast, 8 grams (1.5 teaspoons) of fine sea salt, and 4 grams (1 teaspoon) of sugar and combine into a large bowl. 
2. Mix the dry ingredients together.

3. Pour 9 ounces of cold water into another large bowl.  Slowly add the dry ingredients to the water and mix together.
4. Pour 14 grams or 1 tablespoon of olive oil all over the dough and continue to mix well to incorporate all of the ingredients.
5. Place the dough onto a large work surface (a plastic cutting board or granite/marble countertop work best) and begin kneading. To knead, you want to fold the dough over and press down and away on the cutting board with a bit of force.  Turn the dough 90 degrees and repeat.  Knead for at least 5 minutes.  If the dough becomes too sticky, cover it for 30 minutes with plastic or an inverted clean bowl and let the dough warm up.  Return to kneading (just make sure to knead for at least 5 minutes total) and then form a dough ball.
6. You do not need a perfect dough ball for Grandma pizza so don't go crazy.  To form the ball, fold the dough tight and create a seam.  Rotate the dough and fold again.  Do this 20 times, then pinch the seam side.  Place the dough ball seam side down in an oiled container and cover with plastic wrap.  Refrigerate the dough for at least 12 hours to cold ferment.  Do 24-48 hours if you can plan ahead.

7. Remove the dough 2 hours prior to use to warm up.  Oil the sheet pan with a ⅜ cup of olive oil.  You need plenty of oil.  Remove the dough and place it into the oiled pan.  Using your fingers press down and try to stretch the dough into the pan.  You will not be able to do this right away.
8. Cover the sheet pan with plastic wrap and wait 45 minutes, before returning to stretch the dough.  Depending on how warm the dough is, you might need to repeat the process one more time to completely fill the pan.

How to make the best Grandma pizza

Each number corresponds to the numbered written steps below.

1. Hand crush 1 (28 ounce) can of whole San Marzano or other good quality plum tomatoes in a large bowl.
2. After hand crushing, strain the tomatoes and save the juice for another purpose.  You want to be left with thick tomato pulp with minimal juice.  Season the tomatoes with a ½ teaspoon of Kosher salt, mix well, and set aside.

3. Combine 3 tablespoons of olive oil with 3 cloves of minced garlic in a small bowl to create the garlic oil.
4. Preheat the oven to 450f and set the rack to the lowest level.  Here I am stretching the dough again.  Be sure to keep it covered with plastic after stretching.
5. I highly recommend buying sliced mozzarella cheese at your local deli or supermarket.  If not using already sliced mozzarella, a partially frozen block of cheese is easier to slice.  You'll need 12-16 ounces of sliced mozzarella.  The exact weight isn't as important as covering the dough.
6. Now that the dough has filled the pan almost completely, we can move on to assembly and cooking.

7. In pic 7 above I am pinning a corner with my hands then placing the cheese down and applying light pressure.  This will lock in the corners and prevent them from moving too much.  Layer the remaining cheese in an overlapping shingle pattern, leaving about a ¼" around the edges.
8. Distribute the tomatoes all over the cheese in a random pattern.  Resist the urge to over sauce.  The tomatoes will spread out during the cooking and will create the characteristic Grandma pizza pattern.
9. Drizzle a couple of tablespoons of garlic oil all over the pizza.  If you love garlic, use more.  Bake the pizza in the oven on the lowest rack for 12 minutes, rotating 180 degrees after 6 minutes.  After 12 minutes check the bottom of the pizza with a spatula.  If the pizza is nice and brown, move it to the top oven rack and cook for 6 more minutes. 
10. Remove the pizza from the oven at 18 minutes.  Sprinkle a few tablespoons of Pecorino Romano cheese all over the pizza. 

11. Sprinkle ½ to 1 teaspoon of oregano on the pizza.  In pic 11 I'm using Sicilian oregano and crumbling it in my hands.  Return the pizza to the top rack and cook for 2 more minutes.  Additionally, if the Grandma pizza is not crisp enough on top, broil for 30-60 seconds but watch carefully.  Normally the pizza does not need to be broiled.
12. Here is your perfect Grandma pizza.  

That is how to make the real-deal, New York Grandma pizza.  It is the easiest of the 3 types of New York pizza - the hardest part is waiting for the dough to cold ferment, but it is worth it!

What type of pan for Grandma Pizza?

Many pizza shops use heavy steel pans for their Sicilian and Grandma pies.  They are cooking their pies in a deck oven which browns the bottom quicker.   Most home cooks can't replicate this, though if you have a baking or pizza steel as large as your pan you could try.

If you were to attempt to make this Grandma pizza in a thick steel or cast iron pan in your home oven, the bottom wouldn't get brown enough in time.

For this reason, I recommend using an aluminum pan on the bottom of your oven.  If anything, you'll have to worry more about the bottom burning.  An aluminum pan is thin and will crisp the bottom of the pizza very quickly on the lowest level of the oven. 

A dark aluminum pan like the one seen throughout my pictures works amazingly well.  It's a LloydPans 16 x 12" Grandma pan.

You can also use a standard 18 x 13 half-sheet pan with great results.

Oven temperature and placement

Now you know the type of pan, but what about the oven?

I cook all of my pizzas in a standard 20-year-old GE oven.  I have not tested this pizza using a convection oven, so you may need to adjust the cooking time, oven temperature levels, and of course pan placement.

Note:  Many experts state that convection adds 20-25F degrees to recipes that call for a conventional oven.  

As mentioned above in the detailed steps you should check the bottom of the pizza after 12 minutes of cooking.  If the bottom is very blond, finish cooking it on the bottom rack for the remaining 8 minutes.   

If you're having problems with browning, you could pour 3 more tablespoons of olive oil under the pizza.  Grandma pizza uses a lot of olive oil!

Inevitably, the temperature of all ovens fluctuates.  Your oven is not my oven, and so on.  You may need to play around with the placement and temperatures a bit, but I'm confident that with these instructions you'll be able to make a Grandma pizza that looks just like mine.

Making Grandma pizza dough in a Kitchen Aid mixer

I've shown the process here and on YouTube, (for more pizza check out the 20 pizza videos on my channel) using hand mixing.

Why?  Because I like to show without special equipment.  But if you want to use your mixer all you have to do is:

1. Mix dry ingredients in a large bowl and place half of them and all the water into the Kitchen Aid mixer bowl.
2. With the dough hook attached, mix for 1 minute on low (speed level 1) and begin adding in the remaining dry ingredients.
3. Drizzle the olive oil into the mixing bowl and continue at speed level 1 for 4 more minutes or until the dough is sticking well to the bread hook.
4. Remove the dough, hand knead for 1 minute and cover for 40 minutes.  After 40 minutes, ball the dough, place it in an oiled proofing container and get it in the fridge for at least 12 hours.  Simple!
