Prepare steak marinade by mixing together oil and garlic paste in a small bowl. Brush over both sides of each ribeye.
Cover both sides of ribeyes with Grill Mates Montreal Steak Seasoning. Wrap tightly and let marinate in fridge for a couple hours or overnight.
Begin cooking right before serving. Heat a large pan or skillet over medium heat on stovetop. Add butter and let melt.
Once butter has melted, add ribeyes and sear 1 minute on one side, and then flip and sear 1 minute on the opposite side. Repeat process until desired temperature is met. This will take anywhere from 7-15 minutes depending on desired temp. As a reference point, for a medium steak cook for 10 min.
During periods of searing, take a spoon and scoop melted butter and fat drippings over top of ribeyes.
Serve after cooking.
