Best Grandma Style Pizza in San Diego
Experience Long Island's beloved home-style pizza in San Diego—Grandma pizza, a thin rectangular pie that captures Italian-American nostalgia from the 1970s. Baked in sheet pans heavily coated with olive oil (creating a crispy, almost fried bottom), this "upside-down" pizza features cheese first, then dollops of fresh crushed tomato sauce, finished with garlic-infused oil and oregano. Reminiscent of pizza alla casalinga (housewife-style) from Italian homes, discover where San Diego serves authentic Long Island Grandma pies.
Expert Tip: Pro tip: Authentic Grandma pizza should have a crispy, almost fried bottom from the generous olive oil—flip a corner and check that the underside is golden-brown and crunchy. The sauce should be dolloped in spots, not spread evenly, with visible chunks of fresh plum tomato. If the cheese is on top of the sauce (traditional layering), it's not true Grandma pizza—it must be "upside-down" with cheese first. Look for generous fresh garlic (not garlic powder) and a heavy garlic-oil drizzle finishing the pie. The crust should be thin but tender, not crispy-throughout like Brooklyn style. Grandma pizza is best eaten fresh from the oven when the bottom is at peak crispness; it softens as it cools. Order it when you want rustic, home-style comfort—it's nostalgia in pizza form, simple and satisfying.
Key Characteristics
What Makes It Unique
Grandma pizza's defining characteristic is its "upside-down" assembly: sliced mozzarella cheese goes directly on the dough first, followed by spoonfuls of chunky fresh plum tomato sauce dolloped strategically (not spread evenly) on top. This reverse layering keeps the thin crust crispy despite being baked in heavily oiled sheet pans. The pan is generously coated with olive oil before the dough is added, creating an almost fried, golden-brown bottom with unmistakable crunch—similar to Detroit pizza's frico effect but with olive oil instead of cheese. Unlike thick Sicilian pizza (1+ inch airy crust from extended rising), Grandma pizza uses dough that isn't given extra rise time, resulting in a thinner, denser, more tender crust closer to focaccia. The sauce is simple: fresh squeezed plum tomatoes drained 30+ minutes to remove excess water, combined with fresh garlic, olive oil, and oregano—no cooking required. A heavy drizzle of garlic-infused olive oil finishes the pie, along with Pecorino Romano and fresh basil. The rectangular shape (typically 12x18" sheet pan) allows even, controlled baking. Grandma pizza embodies rustic, home-cooking simplicity—the way Italian nonne (grandmothers) made pizza at home without professional ovens, using what they had: sheet pans, olive oil, fresh garden ingredients.
History & Origins
Grandma pizza originated around the 1970s on Long Island, New York, when Italian-American families who had emigrated became nostalgic for home-country pizza and adapted it to American home kitchens. It resembles "pizza alla casalinga" (housewife-style pizza) made in Italian homes without pizza ovens—using sheet pans and simple, fresh ingredients. The style remained a home-cooking secret until commercial pizzerias discovered it. New York area pizzerias didn't serve Grandma-style pies until approximately 1970, with Long Island shops in the late 1970s/early 1980s first adding them to menus. The breakthrough came around 1994 when Umberto Corteo introduced "Sicilian Grandma pizza" at his pizzerias, Umberto's of New Hyde Park—unlike thick Sicilian pizza, his Grandma version had a thinner crust. King Umberto's (Umberto's) is considered "ground zero of grandma pizza popularity," a pilgrimage-worthy destination where Giovanni Cesarano insists it should have a crispy bottom. The name "Grandma" honors Italian-American grandmothers (nonne) who made this home-style pizza for family gatherings, using sheet pans, olive oil, fresh tomatoes from gardens, and garlic. It represents nostalgia for simpler times, home cooking, and immigrant family traditions—comfort food embodying Italian-American identity on Long Island.

Frequently Asked Questions
What makes Grandma pizza different from Sicilian pizza?
Grandma pizza has a thinner, denser crust (no extended rise time) compared to Sicilian's thick, airy 1+ inch crust. Grandma features "upside-down" assembly with cheese first then sauce on top, while Sicilian typically has traditional layering. Grandma is baked in heavily oiled sheet pans for a fried-like bottom, while Sicilian emphasizes focaccia-like airiness. Grandma represents home-style simplicity; Sicilian is a formal pizzeria style.
Where can I find authentic Grandma pizza in San Diego?
TnT Pizza (East Village) serves Grandma pizzas with crispy Long Island-style crust alongside New York and Detroit styles. Tribute Pizza (North Park) offers rectangular Grandma-style pies with Neo-Neapolitan and NY-style options. Look for pizzerias advertising "Grandma pizza," "Long Island style," or "home-style rectangular" pies with cheese-first assembly and olive oil-crisped bottoms.
Why is the sauce on top of the cheese in Grandma pizza?
The "upside-down" assembly—cheese first, then sauce dolloped on top—is Grandma pizza's signature. This reverse layering keeps the thin crust crispy despite baking in heavily oiled pans. The cheese creates a barrier preventing sauce moisture from soaking the dough, while the sauce stays fresh and bright on top. This technique mirrors Italian home-cooking methods where nonne used what worked in sheet pans.
What does "Grandma pizza" mean and where did it originate?
Grandma pizza originated on Long Island, New York, in the 1970s, named for Italian-American grandmothers (nonne) who made this home-style pizza for families. It resembles "pizza alla casalinga" (housewife-style) from Italian homes—using sheet pans, olive oil, fresh tomatoes, and garlic. Umberto Corteo popularized it commercially in 1994 at Umberto's of New Hyde Park, now considered "ground zero" for Grandma pizza.
Why is Grandma pizza cooked with so much olive oil?
The sheet pan is heavily coated with olive oil before adding dough, creating an almost fried, golden-brown, ultra-crispy bottom—similar to pan-frying. This technique comes from Italian home cooking where nonne used abundant olive oil (central to Italian cuisine) in sheet pans since they lacked pizza ovens. The oil also adds rich flavor and prevents sticking, creating the signature crunchy base.
Is Grandma pizza from Italy or America?
Grandma pizza is Italian-American, not traditional Italian. It originated on Long Island in the 1970s when Italian-American families adapted home-country pizza styles to American kitchens using sheet pans. It resembles Italian "pizza alla casalinga" (housewife pizza) but evolved distinctly in Long Island's Italian-American community. It's American pizza inspired by Italian home-cooking nostalgia.
