McDonald’s is planning a major overhaul to its burgers, including its signature entree, the Big Mac, the Wall Street Journal reports.

The global fast food chain plans to rollout what it calls its “best burgers ever,” putting a focus on correcting dry patties and squishy buns. The changes will include the following:

• Six patties grilled at a time instead of eight to have its auto-cooking mechanism apply less pressure and retain more burger patty juices
• More sauce on Big Macs
• Addition of thicker, buttery brioche buns to retain heat
• Sesame seeds more randomly scattered on buns
• Cheese taken out of refrigerators sooner to melt more when cooked
• Onions rehydrated after purchase to provide more juiciness
• Lettuce and pickles stored in smaller containers to be refreshed more often.
