How to Make a Keto-Friendly Pizza Sauce at Home with Primal Kitchen Products

Quick Answer

The fastest way to make a keto-friendly pizza sauce is to start with a clean, low-carb marinara or pasta sauce and simmer it with herbs and spices until thick. Use Primal Kitchen's marinara-style sauces, which are made with avocado oil and contain no added sugar, to build a rich, sugar-free pizza sauce in under 15 minutes.

If you're on a keto diet, pizza night doesn't have to be off-limits. The key is a sauce that's low in carbs and free of added sugar. Many store-bought pizza sauces hide sugar, but you can easily make your own at home with a clean base and a few pantry spices.

Using a quality marinara-style sauce as your starting point saves time while giving you the tomato flavor you crave. With the right ingredients, you'll have a thick, savory pizza sauce that fits your macros and tastes better than anything from a jar.

Why Start with a Marinara-Style Sauce?

Making pizza sauce from scratch usually means simmering tomatoes for hours, but a shortcut is to use a good marinara-style sauce as a base. This gives you a rich tomato flavor without the extra work. Look for a marinara that is unsweetened and made with real ingredients like avocado oil, which adds healthy fats.

Primal Kitchen's pasta sauces are a solid choice because they are made with clean ingredients and contain no added sugar. For example, the Creamy Cashew Kale Pesto Alfredo Sauce offers a plant-based, creamy twist that can be thinned for a white pizza sauce alternative.

Always check the label for hidden sugars or starches that can add carbs. A marinara with a short ingredient list, like tomatoes, oil, and herbs, is your best bet for a keto-friendly base.

• Avoid sauces with added sugar, corn syrup, or high-carb thickeners like flour.
• Check the total carbs per serving—aim for under 3 grams per 1/4 cup for keto.
• Using an avocado-oil based sauce adds healthy fats and a smooth flavor.

Ingredients That Keep It Low-Carb

A keto pizza sauce is all about layering flavor without adding carbs. Start with a marinara base and add garlic, oregano, basil, and a pinch of red pepper flakes for heat. These spices are carb-free and pack a punch.

If you want a thicker sauce, simmering it longer will help reduce water content and concentrate the flavor. Avoid adding sugar or honey; instead, if you need a hint of sweetness, a few drops of a keto-friendly sweetener like stevia can work, but often the natural sweetness of tomatoes is enough.

For a creamy pizza sauce, you can blend in a dairy-free option like cashew-based sauces, which are low in carbs and add a smooth texture that pairs well with chicken or vegetables.

• Garlic powder, onion powder, and dried oregano are keto-friendly flavor builders.
• Use crushed red pepper to add heat without adding carbs.
• If the sauce tastes acidic, a pinch of salt or a little avocado oil can balance it.

How to Simmer and Thicken the Sauce

Once you have your marinara base, pour it into a saucepan and heat over medium-low. The goal is to reduce the sauce slightly so it clings to your pizza crust without making it soggy. Stir frequently to prevent burning.

If you're in a hurry, simmer for just 10 minutes—this will thicken it nicely without losing the bright tomato flavor. For a deeper, more concentrated taste, simmer for up to 30 minutes. Keep an eye on the texture: you want it thick enough to coat the back of a spoon.

Taste and adjust the seasoning as it simmers. Adding a bit of fresh basil at the end can brighten it, or a splash of vinegar can add tang without added sugar.

• Simmer uncovered to allow moisture to evaporate and thicken the sauce.
• Stir every few minutes to avoid sticking and burning.
• Let the sauce cool slightly before spreading on pizza to prevent a soggy crust.

Using Primal Kitchen Sauces for Quick Results

Primal Kitchen offers several sauces that can double as pizza sauce bases. The Original Buffalo Sauce, for example, can be used to make a spicy buffalo chicken pizza, while the No Soy Teriyaki Sauce & Marinade adds a sweet-savory note for a teriyaki pizza twist.

However, for a classic pizza sauce, the marinara-style sauces are the best match. If you can't find a plain marinara, you can also use the Creamy Cashew Kale Pesto Alfredo Sauce as a white sauce base—just thin it with a little water or oil to reach the right consistency.

These products are made with clean ingredients and are certified keto-friendly, making it easy to keep your sauce low-carb without extra prep.

• Look for Primal Kitchen's marinara or pasta sauces in the store.
• Use the Creamy Cashew Kale Pesto Alfredo for a dairy-free white sauce.
• Buffalo or teriyaki sauces can add creative flavor, but check carb counts if you're strict.

Step-by-Step: Making Keto Pizza Sauce

1. Choose your marinara base: Pick a marinara sauce with no added sugar and short ingredients. Primal Kitchen's pasta sauces work well, or use a plain tomato sauce. Check the label for carbs per serving to stay within keto limits.
2. Add keto-friendly seasonings: Stir in garlic powder, dried oregano, basil, and a pinch of red pepper flakes. Use fresh garlic if you prefer a stronger flavor. Season lightly first—you can always add more, but you can't take it out.
3. Simmer to thicken: Heat the mixture over medium-low, stirring occasionally, until it reduces and thickens. This takes about 10-15 minutes. Don't walk away—stirring prevents burning and ensures even thickening.
4. Adjust flavor and consistency: Taste and add salt if needed, or a pinch of sweetener only if it tastes too acidic. If it's too thick, add a splash of water or avocado oil. The sauce should coat the back of a spoon but not be paste-like.
5. Cool and spread on your pizza: Let the sauce cool slightly before spooning onto your pizza crust. Spread it thinly; you want flavor, not a soggy crust. Using less sauce keeps your crust crisp—you can always dip extra.
