Grimaldi’s Pizza Sauce Recipe: Authentic Coal-Fired Flavor at Home

There’s a reason Grimaldi’s coal-fired pizza sauce stands out—it’s the perfect balance of sweet San Marzano tomatoes, fresh garlic, and aromatic herbs. This version captures that signature flavor without a coal oven.

With just a few simple ingredients and 10 minutes of simmering, you’ll have a smooth, rich sauce ready for your next pie. Store it in the fridge for up to a week or freeze for later.

Ingredients for Grimaldi’s Pizza Sauce

Nine ingredients. One pot. That iconic coal-fired taste right at home.

The tomatoes are non-negotiable here. San Marzano canned tomatoes (the ones in the tall cans) have the right sweetness and low acidity. Whole Foods and Trader Joe’s carry them, but any well-stocked grocery store should have them in the Italian aisle. The olive oil should be something you’d happily drizzle on bread—California Olive Ranch is a solid supermarket pick (worth the extra minute to grab the good stuff).

No fresh basil? Dried basil at one-third the amount works, though it won’t be quite the same. Out of San Marzanos? Regular canned tomatoes are fine in a pinch, but add a pinch of sugar to balance the acidity. The garlic must be fresh though—jarred minced garlic has a harsh, metallic bite (don’t skip this part). If you’re sensitive to spice, skip the red pepper flakes entirely.

This sauce keeps beautifully. Fridge for up to 1 week, or freeze in ice cube trays for 3 months. I like to portion it into small jars so it’s ready for pizza night anytime (frozen works in a pinch).

Step-by-Step Instructions for Grimaldi’s Pizza Sauce

Here’s my tested method for capturing that authentic coal-fired flavor you crave.

Step 1: Sauté Aromatics in Olive Oil

Heat the 2 tbsp Extra-Virgin Olive Oil in a medium saucepan over medium-low heat. Add the 4 cloves Garlic Cloves (minced) and cook for 1-2 minutes, stirring constantly, until fragrant but not browned. The garlic should sizzle gently—if it starts to color, lower the heat immediately.

This step builds the flavor foundation. I always use fresh garlic for its bright, pungent character. The olive oil carries the garlic’s aroma throughout the sauce, creating depth that dried garlic can’t match.

Step 2: Incorporate Tomatoes and Tomato Paste

Add the 28 oz San Marzano Tomatoes (crushed by hand) and 1 tbsp Tomato Paste to the saucepan. Stir well to combine with the olive oil and garlic. Increase heat to medium and bring to a gentle simmer.

San Marzano tomatoes are key—they’re sweeter and less acidic than standard varieties. The tomato paste adds body and intensifies the tomato flavor. I crush the tomatoes with my hands right over the pot to avoid losing any precious juices.

Step 3: Season and Simmer for Depth

Stir in the 1 tsp Dried Oregano, 1 tsp Sea Salt, 0.5 tsp Black Pepper, and 0.25 tsp Red Pepper Flakes. Reduce heat to low and let the sauce simmer uncovered for 20-25 minutes.

You’ll notice the sauce thicken slightly and deepen in color. The red pepper flakes add a subtle warmth that balances the tomatoes’ natural sweetness. Stir occasionally to prevent sticking, especially as the sauce reduces.

Step 4: Finish with Fresh Basil

Remove the sauce from heat and stir in the 0.25 cup Fresh Basil Leaves (torn by hand). Let it sit for 5 minutes to allow the basil’s aromatic oils to infuse the sauce. The residual heat will gently wilt the basil without turning it bitter.

Fresh basil is non-negotiable for authentic flavor—it adds a bright, herbal note that dried basil can’t replicate. I tear the leaves rather than chopping to prevent bruising and maintain the best texture.

Step 5: Cool and Use or Store

Let the sauce cool to room temperature before using. For pizza, spread a thin layer—about ¼ cup per 12-inch pie—over your dough. The sauce will continue to develop flavor as it cools, becoming more concentrated and complex.

This makes enough for 4 pizzas. Store leftovers in an airtight container in the refrigerator for up to 5 days, or freeze for 3 months. The flavor actually improves after a day as the ingredients meld together.

Flavor Customization for grimaldis pizza sauce

Spice It Up

For a bolder version, increase the red pepper flakes to ½ tsp. This adds noticeable heat without overpowering the tomatoes. I also recommend adding a pinch of cayenne pepper for extra kick. 🌶️

Herb Variations

Swap the dried oregano for 1 tsp dried thyme or 1 tsp dried marjoram. Thyme brings earthiness, while marjoram offers a sweeter, more floral note. Both complement the San Marzano tomatoes beautifully.

Garlic Lovers

Double the garlic cloves to 8 cloves for a punchier, more aromatic sauce. Roast the garlic first for a sweeter, milder flavor that blends seamlessly into the sauce.

Sweet and Smoky

Add 1 tbsp brown sugar to balance acidity in standard tomatoes. For smokiness, include ½ tsp smoked paprika with the oregano. This mimics the coal-fired depth Grimaldi’s is famous for.

Creamy Twist

Stir in 2 tbsp heavy cream at the end for a richer, velvety sauce. This works especially well for white pizzas or as a dipping sauce. The cream mellows the acidity beautifully. 💛

Fresh Herb Boost

Mix in 1 tbsp fresh oregano or 1 tbsp fresh parsley with the basil. Fresh herbs add brightness and complexity that dried versions can’t match.
