Essential Ingredients for Homemade Keto Marinara Sauce
Choosing the Right Tomatoes
When making keto marinara sauce, selecting quality tomatoes is crucial. Opt for fresh, ripe tomatoes if available, as they provide a rich flavor profile. Alternatively, canned tomatoes are a great option. Look for no sugar added marinara varieties, such as San Marzano tomatoes, which are known for their sweetness and low acidity.
Herbs and Spices for Flavor
Fresh herbs like basil, oregano, and thyme can elevate your keto marinara sauce. These herbs not only enhance the taste but also align with low-carb dietary guidelines. For added flavor, consider using garlic – the result is a savory keto marinara for pizza that can also double as a delicious dip.
Cooking Fats and Sweeteners
In traditional marinara recipes, olive oil is often the go-to fat. It adds richness and a healthy dose of monounsaturated fats, making it perfect for a healthy marinara sauce. Additionally, if you prefer a slightly sweet flavor, consider using a sugar substitute, like erythritol or monk fruit, to maintain the sauce's keto integrity.

Using Fresh Ingredients for Marinara
When making a fresh marinara sauce, consider chopping fresh vegetables such as bell peppers or zucchini for added nutrition and flavor. This can create a nutrient-rich base for your sauce that’s not only tasty but also satisfying. Experimenting with seasonal vegetables can lead to a unique flavor profile tailor-made for your palate.
Storage Tips for Marinara Sauce
Make a big batch of homemade marinara sauce and store it for later use. To keep it fresh and flavorful, store it in airtight containers in the refrigerator for up to a week, or freeze it in portions for ≈ 3 months. This approach aligns perfectly with meal prep methods, ensuring you always have keto marinara sauce at hand for quick dinners or lunches.
