Rich Handmade White Pizza Sauce
Elevate your homemade pizzas with this velvety white sauce. Infused with fresh rosemary, onion, and herbs, it offers a fragrant, creamy base that beats any store-bought alternative.
Many pizza shops rely on semi-finished white sauces, but taking the time to build one from scratch transforms the entire pie. By infusing milk with aromatics like onion and rosemary before blending it into a classic roux, the sauce develops a profound depth of flavor. It requires patience and a gentle, low flame, but the resulting delicate, milky richness is entirely worth the effort.
Ingredients
- 500 ml fresh whole milk
- 50 g high-quality yellow butter
- 50 g white flour or glutinous rice flour
- 14 onion
- 1 sprig fresh rosemary
- 1 tsp pizza herbs
Instructions
- 1Melt the butter

Place chunks of high-quality yellow butter into a preheated pan over low heat. Allow the butter to melt slowly until it begins to bubble gently. This fat base will eventually combine with flour to create the roux, providing the sauce with its rich, velvety structure.
Tip: Keep the heat low during this stage to prevent the butter from browning or burning, which would alter the clean milky color of the final sauce. - 2Infuse the milk with aromatics

In a separate pot, combine fresh whole milk with aromatic ingredients including onion pieces, fresh rosemary sprigs, and pizza herbs. Heat the mixture gently to allow the flavors of the spices to fully penetrate the milk. This infusion is the secret to a fragrant, professional-tasting white sauce.
Tip: Do not bring the milk to a rolling boil; a gentle simmer is enough to extract the essential oils from the herbs without scorching the milk. - 3Create the roux

Gradually add white flour (or glutinous rice flour for a smoother texture) to the melted butter. Use a spatula to stir-fry the mixture constantly until it forms a uniform, thick paste. Cooking the flour briefly in the fat removes the raw taste and prepares the base for thickening.
Tip: Stir vigorously to ensure there are no dry flour pockets, ensuring a completely smooth sauce later on. - 4Combine milk and roux

Slowly pour the strained, herb-infused milk into the pan with the butter and flour paste in stages. Continue to stir or whisk as you pour to help the liquid merge seamlessly with the roux. This gradual process prevents lumps from forming and ensures a delicate texture.
Tip: Adding the milk in small increments at the beginning is crucial for maintaining a smooth consistency. - 5Thicken the sauce

Keep the heat on low and continue stirring the mixture with a wooden spatula. As the sauce heats up, the flour will hydrate and thicken the milk into a lush, creamy consistency. Be patient and keep the spatula moving to prevent the bottom from sticking or burning.
Tip: Constant movement is the key to a perfect handmade sauce as it ensures the heat is distributed evenly. - 6Simmer until thickened

Continue to cook the sauce over low heat, stirring constantly to prevent any burning or clumping. The mixture will gradually transform into a smooth, delicate, and thick consistency. The goal is a velvety texture that coats the back of a spoon, carrying the deep aroma of the infused spices.
Tip: Patience is key here—never rush the heat. A slow simmer ensures the flour cooks through and the milk achieves a perfectly glossy finish.
