My whole house smells like burnt burger patties and I need help

Late in the afternoon yesterday my brother and I decided to make burgers. We cooked too hot and there was a lot of smoke coming from the burgers for the duration of the cooking. It was about twenty minutes. Still dont know what was going through our heads when we did that. We opened every door and window, turned on the hvac, lit candles, and sprayed febreeze. Eventually we had to go to sleep so doors leading outside were shut overnight. This morning the smell is still strongly here, like a fast food kitchen. Its been extremely stressful trying to figure out what to do. Any suggestions on how to get rid of this odor asap?
