A copycat recipe of Lawry's seasoned salt is available from Top Secret Recipes and includes salt, sugar, paprika, onion powder and turmeric as well as cornstarch and garlic powder. The spice mix takes approximately five minutes to prepare.
In a small bowl, combine 2 tablespoons salt, 2 teaspoons sugar and 1/2 teaspoon paprika. Also add 1/4 teaspoon each of turmeric, garlic powder, onion powder and cornstarch. Mix well before pouring the spice mix into a clean, dry spice bottle with a shaker top or another airtight container. Although the recipe earns more than four out of five stars from user ratings as of 2015, some reviewers recommend adding 1/4 teaspoon of celery salt for a more authentic flavor. If desired, you can also substitute arrowroot powder or potato starch for the cornstarch.
Use the imitation Lawry's seasoned salt on prime rib, chicken, casseroles and steaks, or sprinkle it atop potato dishes such as mashed potatoes, French fries, hash browns or baked potatoes. The original Lawry's seasoned salt was created in 1938 to season prime ribs at the Lawry's restaurant in Beverly Hills, and it is now available from McCormick. The spice mix contains tricalcium phosphate to prevent caking as well as unspecified natural flavors, but it contains no monosodium glutamate.
