There’s something incredibly satisfying about a pot of rich, aromatic marinara sauce simmering on the stove. While store-bought sauces are convenient, they’re often loaded with hidden sugars and preservatives. That’s why I’m obsessed with making my own! This keto-friendly marinara is a game-changer—it’s packed with robust Italian flavor, uses simple pantry staples, and comes together in about 30 minutes. It’s my go-to for everything from zucchini noodle bolognese to a simple dipping sauce, proving that healthy eating never has to be boring.
