Steak Alfredo

Heat milk and cream in a saucepan over medium heat until simmering, about 5 minutes. Slowly whisk in Parmesan and Romano cheeses. Remove from heat.

Whisk egg yolks together in a heat-proof bowl; slowly whisk in about ¼ cup hot cream mixture to temper eggs. Slowly whisk egg yolk mixture into the cream mixture in the saucepan; season with salt and black pepper. Cool Alfredo sauce; refrigerate until needed.

Whisk salad dressing, rosemary, and lemon juice together in a large glass or ceramic bowl. Add steak and toss to evenly coat. Cover the bowl with plastic wrap and marinate in the refrigerator for 4 hours.
