Ingredients for Lou Malnati’s Pizza Sauce

Ten ingredients deliver that iconic Chicago-style tang and robust depth for authentic pizza sauce.

The tomatoes are non-negotiable—San Marzano whole peeled tomatoes from Italy provide the sweet, low-acid base that defines authentic Chicago sauce. Eataly or Whole Foods carry them, but most supermarkets have a decent alternative. Tomato paste adds depth; double-concentrated versions eliminate the need for reducing. The olive oil should be something you’d drizzle on bread—California Olive Ranch is a reliable supermarket brand.

No San Marzano tomatoes? Muir Glen organic works in a pinch. Fresh garlic can replace minced at a 1:1 ratio, though the flavor profile differs slightly. Dried herbs are standard here, but fresh can be used at triple the amount—just saute them first to mellow the flavor. The sugar balances acidity, but honey or maple syrup can substitute if preferred.

Sauce keeps for 1 week in the fridge in an airtight container. For longer storage, freeze in ice cube trays—perfect single-serving portions. The flavors deepen overnight, so making it a day ahead is ideal (worth the extra minute).

Step-by-Step Instructions for Chicago-Style Pizza Sauce

This method ensures the perfect balance of tangy, savory depth for authentic Chicago-style pizza.

Step 1: Prepare the Tomato Base

Drain the 28 oz San Marzano Whole Peeled Tomatoes and crush them by hand directly into a large bowl. I prefer this method over blending for a rustic texture that clings perfectly to pizza dough.

Add the 3 tbsp Tomato Paste to the crushed tomatoes and mix thoroughly. The double-concentrated paste intensifies the tomato flavor, which is essential for countering the richness of Chicago-style deep dish. This combination creates a thick, spreadable base.

Step 2: Sauté Aromatics in Olive Oil

Heat the 0.25 cup Extra-Virgin Olive Oil in a medium saucepan over medium heat until it shimmers. The high-quality oil adds depth and carries the flavors of the aromatics throughout the sauce.

Add the 4 cloves Garlic Cloves, minced, and cook for 30-45 seconds until fragrant but not browned. Garlic burns easily, so keep it moving in the pan. This step builds the aromatic foundation that defines the sauce’s character.

Step 3: Combine and Simmer the Sauce

Add the tomato mixture to the saucepan with the garlic and oil. Stir in the 2 tsp Dried Oregano, 2 tsp Dried Basil, 1 tsp Granulated Sugar, 1.5 tsp Kosher Salt, 0.5 tsp Ground Black Pepper, and 0.5 tsp Red Pepper Flakes.

The sugar balances the natural acidity of the tomatoes, while the Diamond Crystal kosher salt enhances all the flavors without overpowering. The red pepper flakes add a subtle heat that’s characteristic of Lou Malnati’s signature taste. Crush the dried basil between your fingers as you add it to release its essential oils.

Reduce heat to low and let the sauce simmer uncovered for 45-60 minutes, stirring occasionally. You’ll notice the sauce darkening and thickening slightly—this concentration of flavors is crucial for that authentic Chicago-style punch.

Step 4: Finish and Cool the Sauce

After simmering, taste and adjust seasoning if needed. The Mediterranean oregano should be prominent but balanced with the sweetness from the tomatoes and sugar. The sauce should have a chunky texture that will spread beautifully on your pizza crust.

Remove from heat and let the sauce cool to room temperature. This cooling step is important—it allows the flavors to meld completely and prevents the sauce from making your pizza dough soggy when assembling. The final sauce should be thick enough to hold its shape on a spoon.

Dietary Considerations for This Dish

Gluten-Free Adaptation

This sauce is naturally gluten-free as written, since all ingredients are whole foods without wheat derivatives. The San Marzano tomatoes and spices contain no gluten, making it safe for most gluten-sensitive individuals. Always verify your tomato paste brand for hidden additives.

Vegan Variation

No animal products are used in this recipe, so it’s inherently vegan-friendly. The olive oil serves as the fat base, and all seasonings are plant-derived. Perfect for topping vegan cheese alternatives on your pizza.

Low-Sodium Option

To reduce sodium, cut the kosher salt by half and use no-salt-added tomato paste. The natural sweetness of San Marzano tomatoes means you won’t miss much salt. Taste before adding the full amount.

Sugar-Free Adjustment

Omit the granulated sugar entirely—San Marzano tomatoes are naturally sweet. For extra sweetness without sugar, add 1 tsp honey or maple syrup. The acidity remains balanced without additional sweeteners. 💪

Allergen Awareness

This sauce contains no common allergens like dairy, nuts, or soy. The only potential concern is nightshade sensitivity from tomatoes. If garlic is an issue, reduce to 2 cloves or substitute 1 tsp garlic powder.

Calorie-Conscious Mods

To reduce calories, cut the olive oil to 2 tbsp—the flavor impact is minimal. The sauce remains rich and flavorful with this small adjustment. Each serving contains about 50 calories as originally written.
