I seldom buy spice blends because I don't use them very much AND you never really know what is in them; some are heavy on garlic, some are heavy on onion and even more of them are heavy on ..."what the heck is that"". When that happens, the $5 jar goes right in the trash, what a waste. Nowadays, when the occasional recipe calls for Italian seasoning, I just mix up this one, it is excellent.
2 1/4 teaspoons dry basil
2 1/4 teaspoons dry oregano
2 1/4 teaspoons dry parsley
1/4 teaspoon garlic powder (not garlic salt)
1/4 teaspoon onion powder (not onion salt)
1/4 teaspoon fennel seed
1/4 teaspoon dry thyme
1/4 teaspoon dry rosemary
1/4 teaspoon black pepper
pinch dry red chili flakes
Basically you just mix all of these ingredients together, however I do an extra step: I measure out the bulky spices, like the fennel seed, rosemary and chili flakes, THEN I work them over a little in my mortar and pestle so it breaks them up which helps distribute their flavor more evenly to the finished spice blend. This step isn't absolutely necessary, but it works well.
