โญ Avocado Oil (Best Vegan Option)
3/4 tablespoon per 1 tablespoon of butterAvocado oil is a monounsaturated fat with a high smoke point, making it suitable for cooking burgers without burning. It adds moisture and fat but is liquid at room temperature, so it doesn't contribute to the firmness butter provides.
Use slightly less avocado oil than butter to avoid excess greasiness. Mix it into the meat or brush lightly on patties before grilling.
The final burger will be moist and tender but may lack the slight firmness and mouth-coating richness butter imparts.
