Steak Frites with Béarnaise Sauce - a restaurant classic that combines perfectly seared steak, crispy fries, and a velvety herb-infused sauce. This recipe shares professional secrets learned from making this sauce dozens of times in restaurant kitchens.
During my years in professional kitchens, I made this béarnaise sauce over fifty times before being allowed to serve it to guests. Each batch taught me something new about the delicate dance between heat and emulsion.
Essential Ingredients
- Ribeye steak: Choose well-marbled meat for best results
- Russet potatoes: Their starch content creates the perfect fry
- Fresh tarragon: The signature flavor of béarnaise
- Egg yolks: The foundation of the sauce
- Quality butter: Don't skimp here - it makes the sauce
- Shallots: Adds subtle depth to the béarnaise
Step-by-Step Creation
Prepare the Fries:Cut potatoes uniformly
Soak in ice water (2 hours minimum)
First fry at 275°F until tender
Freeze briefly between fryings
Final fry at 375°F for golden perfection
Master the Béarnaise:Reduce shallots and herbs with vinegar
Whisk yolks over gentle heat
Gradually emulsify butter
Watch temperature carefully
Temperature Control Mastery
Keep béarnaise warm but not hot (135°F max)
Steak needs very hot cast iron (450°F+)
Monitor oil temperature between batches
Rest steak 5-10 minutes before slicing
Troubleshooting Béarnaise
If sauce breaks: Whisk in hot water droplets
If too thick: Add warm water gradually
If too thin: Continue whisking off heat
If eggs scramble: Start over, lower heat
