Wagyu Ribeye with Blender Béarnaise Sauce & Hand-Cut Fries
-
This Wagyu cottage pie takes a much-loved family favourite to new heights — rich, slow-simmered mince with garlic, thyme, and a hint of cumin, topped with a cloud of buttery, parmesan-flecked mash that bakes up golden and irresistible.
Ingredients
Wagyu Ribeye
- 2 First Light Wagyu ribeye steaks
- 1 tbsp olive oil
- 1 tbsp butter
- 2 garlic cloves, smashed
- 1 sprig rosemary or thyme
Hand-Cut Fries
- 3 large Agria potatoes
- Vegetable oil, for frying
- Sea salt, to finish
Blender Béarnaise Sauce
- 2 egg yolks
- 2 tbsp white wine vinegar
- 2 tbsp dry white wine
- 1 small shallot, finely chopped
- 1 tsp crushed peppercorns
- 125g clarified butter/ghee (hot, melted)
- 1 tbsp fresh tarragon leaves, finely chopped
- 1/2 tsp lemon juice
- 1/2 tsp salt

Cooking Method
- Peel potatoes and cut into thick batons (about 1cm). Soak in cold water for 30 minutes to remove starch.
- In a deep fryer or deep heavy-bottom pot, heat oil to 150°C. Dry potatoes well and fry for 4-5 minutes until soft but still pale. Drain on paper towels.
- Let them rest completely – chilling helps crisp them later.
- Remove the Wagyu ribeye from the fridge 30 mins before cooking. Pat dry and season generously with salt and pepper.
- Make the Blender Béarnaise Sauce. In a small saucepan, combine vinegar, wine, shallot, and peppercorns. Simmer until reduced to about 1 tablespoon of liquid. Strain and cool slightly.
- Add the reduction and egg yolks to a blender. Blend for 10 seconds to combine.
- With the blender running on low, slowly drizzle in the hot melted butter until the sauce thickens and turns glossy.
- Add chopped tarragon, lemon juice and a pinch of salt. Pulse once or twice to mix.
- Keep warm over a bowl of hot water or in a small thermos – not on direct heat.
- Heat a heavy pan (cast iron is ideal) over medium-high. Add oil, then the steaks. Sear 2 minutes per side for medium-rare.
- Add butter, garlic, and rosemary. Tilt pan and spoon the foaming butter over the steaks for 30-60 seconds.
- If you have a meat thermometer, cook until the internal temperature is around 54°C before resting.
- Transfer to a warm plate, tent loosely with foil, and rest 5-10 minutes.
- Once the potatoes have cooled, increase the oil temperature to 190°C and fry until golden and crunchy, about 3-4 minutes. Drain and toss immediately with sea salt.
- Slice the rested ribeye against the grain. Serve with hand-cut fries and a generous pour of the Blender Béarnaise Sauce.
