What Makes our Chicago Deep Dish Great? Our Ingredients! Tomato - Crucial to the Lou Malnati's Pizza Recipe Each year a team from Malnati’s goes to California and meets personally with the tomato growers. The finest vine ripened plum tomatoes are then blended and canned exclusively for Lou Malnati's use. The trip is well worth the effort when the result is continuing our tradition as making some of the best deep dish pizzeria in Chicago! Cheese - Quality & Flavor are Essential. We strive to maintain long term relationships with our vendors, which is why we have used the same Wisconsin dairy farm for over 40 years as our source for mozzarella cheese. The unique flavor and texture of their cheese is vital to the Lou Malnati's pizza recipe. Dough - Flaky, Buttery, Delicious Our dough is patted out by hand and raised up high on the sides of a seasoned deep dish pizza pan. True Chicago-style pizza crust is actually rather thin but sturdy enough to hold the delicious toppings. The secret recipe for the flakey, buttery crust has been passed down for generations and is unmatched in flavor and taste.
