This simple and delicious, slow-simmered sauce is bursting with flavor. The key? San Marzano tomatoes! San Marzano tomatoes are sweeter and less acidic, making this marinara sauce a homerun! And we’re making this easy for you, with Magnum seasoning as the only seasoning shaker you need for this recipe. The coarse garlic, onion, crushed red pepper flakes, kosher salt, and cracked black pepper in Magnum is everything you need to bring bold flavor to your sauce!
