How Many Calories Are in a Lou Malnati’s Deep Dish Slice?
Short answer: more than you think, and honestly, it is worth it once in a while. A single slice of Lou Malnati’s deep dish cheese pizza runs about 300 calories for a 4-ounce slice, with 15g of fat, 26g of carbs, and 15g of protein. The Chicago Classic, loaded with sausage, leans, and extra cheese, pushes a medium slice to about 670 calories with 41g of fat. The Lou, their spinach-mushroom-tomato signature, sits in the middle at roughly 490 to 599 calories per slice depending on size.
What drives the number? That famous butter crust, for one. Deep dish pies are heavy by design: thick cheese, layers of sausage or toppings, and chunky tomato sauce. A “slice” at Lou Malnati’s is also a generous serving, not a skimpy triangle. If you eat three slices of Chicago Classic deep dish, you are looking at roughly 2,000 calories before drinks or dessert. Planning around that one number honestly changes how you order.
What About Lou Malnatis Thin Crust Calories?
Here is the good news for anyone watching the numbers. Switching to thin crust nearly halves your per-slice calories. A large Deluxe thin crust slice comes in around 330 calories, while The Lou thin crust is about 310 (large) or 260 (small) per slice. The lightest option on the board is the lower-fat cheese thin crust at just 220 calories a slice.
Three slices of thin crust can run fewer calories than two slices of deep dish. Same great sauce and cheese flavor, just a lot less crust and cheese weight. If the deep dish numbers make you wince, thin crust is your move. It still tastes like Lou Malnati’s, which is the whole point of going.
Which Lou Malnati’s Items Pack the Most Calories?
The heavyweight champion is the Chicago Classic deep dish at 670 calories per medium slice. The Lou deep dish (large) is next at 599, followed by The Lou deep dish (small) at 490 and cheese and spinach deep dish at 429 per slice. Now, here is the sneaky one: the Malnati Salad, without croutons, is listed at around 1,306 calories for a full order, mostly from cheese, salami, and dressing. Salads are not always the light choice.
The kids spaghetti with meat sauce lands at about 524 calories per serving, which is pretty reasonable for a kids menu. Honestly, the biggest calorie bomb is not any single item, it is the combo of deep dish plus a full salad plus a sweet drink. That is easily a 2,500+ calorie meal if you are not paying attention.
What’s the Lowest Calorie Meal at Lou Malnati’s?
If you want to keep it light, here is my playbook. Order a small thin crust pizza, stick to two slices (about 440 to 520 calories depending on toppings), and ask for a side salad with dressing on the side. The lower-fat cheese thin crust slices at 220 calories each are the single lightest pizza option on the menu.
A few more tricks that actually work: pick vegetable toppings over sausage and pepperoni, skip the extra cheese, and drink water or an unsweetened drink instead of soda. You still get the full Lou Malnati’s experience, just a lighter version of it. And here is the thing, nobody is judging you for eating two slices and stopping. Okay, maybe your friends are judging you a little.
Where Can I Find the Official Lou Malnatis Nutrition PDF?
Lou Malnati’s keeps full nutrition information on its official website at loumalnatis.com/nutritional-information, and they note they keep updating it as more items are tested. That page is the source of truth for the current numbers, since values can shift when recipes or suppliers change.
One important caveat they flag: nutritional values vary if you add or remove toppings or ingredients, so anything loaded with extra cheese or sausage will run higher than the standard figures. The table above rounds published figures to whole slices, so treat them as solid estimates, not lab results. When in doubt, check the official page before you order.
