Taco seasoning typically contains a blend of various spices that work well together for seasoning Mexican or Tex-Mex foods. The main ingredients in taco seasoning usually include chili powder, ground cumin, garlic powder, paprika (or smoked paprika), oregano, salt, and pepper. Some recipes may also include onion powder and red pepper flakes. Store-bought taco seasoning often contains additives like MSG, sugar, and preservatives, which can be avoided by making your own seasoning at home
