The Direct Answer You Need Right Now

If you're standing in your kitchen wondering "can I use oregano instead of Italian seasoning" for tonight's dinner, here's what matters most: You can substitute pure oregano for Italian seasoning only in Southern Italian recipes like pizza or tomato-based sauces, but you'll need to add complementary herbs to compensate for missing flavors. For most other dishes, Italian seasoning contains too much basil and not enough oregano to work as a replacement.

• For Italian seasoning → Oregano: Use 1 teaspoon oregano + ¼ teaspoon dried basil + ⅛ teaspoon thyme per tablespoon of Italian seasoning
• For Oregano → Italian seasoning: Use ¾ tablespoon Italian seasoning per teaspoon of oregano (but avoid in pizza sauce)

• Basil (30%)
• Marjoram (15%)
• Thyme (10%)
• Rosemary (5%)

Can I use oregano instead of Italian seasoning in chicken parmesan?

Yes, but use only ¾ the amount of oregano compared to Italian seasoning. Chicken parmesan benefits from Italian seasoning's basil, so consider adding a pinch of dried basil if using pure oregano.
