Vegetarian Pizza Sauce Recipe: Herb-Infused Tomato Base for Plant-Based Pies

This herb-infused tomato base elevates any plant-based pie with its rich, balanced flavors. The sauce comes together quickly with simple ingredients, delivering depth without overpowering toppings.

Unlike store-bought versions, this homemade sauce offers restaurant-quality taste with no preservatives. It’s versatile enough for thin crust, deep dish, or flatbread styles.

Ingredients for Vegetarian Pizza Sauce

Ten simple ingredients deliver restaurant-quality depth for any plant-based pie base.

For authentic flavor, San Marzano tomatoes are non-negotiable—their sweetness and low acidity create the perfect foundation. Whole Foods and Italian specialty stores carry them, but most supermarkets have a decent alternative. The extra-virgin olive oil should be high quality (look for first cold-press labels) as it’s a primary flavor carrier in this sauce.

No fresh basil? Dried basil at one-third the amount works, but add it earlier in cooking to rehydrate. Missing oregano? Marjoram offers a similar profile. For heat, cayenne pepper at half the quantity substitutes for red pepper flakes. The balsamic vinegar can be swapped with red wine vinegar (slightly sharper) or omitted entirely if you prefer a cleaner tomato taste.

Sauce keeps 5 days refrigerated in an airtight container, or freeze for 3 months. Portion into ice cube trays for single-use servings. The flavors deepen after 24 hours, making it ideal for meal prep (worth the extra minute to plan ahead).

Step-by-Step Instructions for Herb-Infused Tomato Pizza Sauce

Master the technique for a balanced, flavorful foundation that elevates any plant-based pie.

Step 1: Prepare the Tomato Base

Begin by crushing the 28 oz San Marzano Whole Peeled Tomatoes by hand directly in their can. This preserves texture better than mechanical crushing. Pour the tomatoes and all their juices into a heavy-bottomed saucepan.

I prefer hand-crushing because it leaves some chunkiness for texture while releasing the perfect amount of liquid. The San Marzano variety offers the ideal sweetness and low acidity for pizza sauce, creating a balanced foundation for your toppings.

Step 2: Sauté Aromatics in Olive Oil

In a separate skillet, heat the 2 tbsp Extra-Virgin Olive Oil over medium heat until it shimmers. Add the 4 cloves Fresh Garlic Cloves (minced) and cook for 1-2 minutes until fragrant but not browned.

Garlic burns easily, so keep the heat moderate and stir constantly. The goal is to mellow its sharpness while developing complexity. Remove from heat immediately when the garlic turns pale gold and smells sweet—this prevents bitterness.

Step 3: Combine and Simmer the Sauce

Add the garlic-oil mixture to the saucepan with tomatoes. Stir in the 1 tbsp Dried Oregano, 1 tsp Dried Thyme, 1.5 tsp Sea Salt, 0.5 tsp Black Pepper, and 0.5 tsp Red Pepper Flakes. Bring to a gentle simmer over medium-low heat.

Rub the dried thyme between your fingers as you add it—this releases its essential oils for maximum flavor. The red pepper flakes add subtle warmth that complements the herbal notes without overpowering the sauce.

Step 4: Finish with Fresh Basil and Balsamic

Reduce heat to low and let the sauce simmer uncovered for 20-25 minutes, stirring occasionally. The mixture should thicken slightly but remain spreadable. When it reaches your desired consistency, remove from heat.

Stir in the 0.25 cup Fresh Basil Leaves (chopped) and 1 tbsp Balsamic Vinegar. The basil adds bright, fresh notes while the balsamic provides depth and balances the tomatoes’ natural acidity. Let the sauce cool to room temperature before using.

Step 5: Adjust Seasoning and Texture

Taste and adjust seasoning if needed, though the measured 1.5 tsp Sea Salt should be perfect for the 28 oz San Marzano Whole Peeled Tomatoes. For a smoother texture, pulse briefly with an immersion blender, but I prefer leaving it slightly rustic.

This sauce keeps in the refrigerator for up to 5 days or can be frozen for 3 months. The flavors deepen over time, making it even better the next day for your vegetarian pies.

Creative Variations of This vegetarian pizza sauce

Spicy Arrabbiata Style

Boost the heat by increasing red pepper flakes to 1 tsp and adding ½ tsp cayenne pepper. I also like stirring in 1 tbsp tomato paste for extra richness. This variation pairs perfectly with spicy sausage alternatives on your pie.

White Sauce Alternative

Skip the tomatoes entirely and blend 1 cup ricotta cheese with ¼ cup grated Parmesan, 2 tbsp olive oil, and 1 minced garlic clove. Season with salt and white pepper for a creamy base that works wonderfully with spinach and artichoke toppings. 💛

Roasted Garlic Variation

Replace raw garlic with 6 cloves roasted garlic for a sweeter, deeper flavor. Roast whole cloves at 400°F for 15 minutes with olive oil before adding to the sauce. The caramelized flavor adds incredible depth to your base.

Sun-Dried Tomato Twist

Blend ¼ cup sun-dried tomatoes (oil-packed) into the finished sauce for intense umami. I use Bella Sun Luci brand for consistent quality. This variation works especially well on flatbreads with goat cheese and caramelized onions.

Add 1 tsp sugar to balance the tanginess of sun-dried tomatoes if needed. 🔥

Pesto Swirl Option

After the sauce cools, swirl in 2 tbsp basil pesto for a marbled effect. Use store-bought or homemade—both work beautifully. This creates gorgeous visual appeal and adds herby brightness to each bite.
