There is something undeniably intimate about cooking for someone you love. The rhythm of the kitchen slows, every gesture becomes intentional, and even the simplest ingredients feel elevated when they’re chosen with care. This dish is built for that kind of evening—where the lights are low, the conversation unhurried, and the meal feels like a quiet celebration.
These sous vide portobello “steaks” take a humble mushroom and treat it like royalty. Slow, gentle cooking transforms each cap into something tender, juicy, and unexpectedly luxurious. Then comes the showstopper: a velvety plant-based “bone marrow” butter, infused with miso, herbs, and citrus, shaped into elegant batons that melt dramatically into the warm gills. It’s a steakhouse theatre, recreated for the plant-forward, modern romantic.
Whether you’re cooking for a partner, a dear friend, or simply for yourself, this recipe invites you to savour the art of slowing down. It’s a little sensual, a little playful, and absolutely memorable—perfect for an evening meant to linger.

Ingredients
Portobello “Steaks”
• 8 large portobellos, stems removed
• 2 tbsp olive oil
• 1 tbsp soy sauce
• 1 tbsp balsamic vinegar
• 2 garlic cloves, smashed
• 4 sprigs thyme
• Salt and pepper, to taste
Plant “Bone Marrow” Butter
• 120 g refined coconut oil, softened
• 1 tsp white miso
• 1 tbsp parsley, minced
• 1 tbsp chives, minced
• ½ tsp lemon zest
• Freshly ground black pepper
• Optional: bone-shaped silicone moulds
Method
1. Season and bag
Brush the portobellos with olive oil, soy sauce, and balsamic. Add garlic and thyme. Season lightly with salt and pepper, then vacuum seal in a single layer.
2. Sous vide to perfection
Cook at 85°C for 60 minutes. The mushrooms will become supple, deeply flavoured, and beautifully juicy.
3. Prepare the marrow butter
Beat the softened coconut oil with miso, parsley, chives, lemon zest, and pepper until smooth. Pipe or spoon the mixture into bone-shaped moulds (or any small mould), then chill until firm.
4. Sear for the steak effect
Remove the mushrooms from the bag and pat dry. Sear in a ripping-hot pan for 60–90 seconds per side to achieve a deep, golden crust.
5. Plate with a touch of romance
Stack two caps per plate for height and drama. Crown each stack with a chilled “marrow” baton and let it slowly melt into every crevice.
A Dish Made for Slow Evenings
As the herb-miso butter melts, the portobellos take on an almost decadent richness—warm, savoury, and deeply satisfying. This is comfort food dressed up for a night out, or better yet, a night in. Pair it with a bold red wine, soft candlelight, and someone who appreciates both good food and good company.
This recipe isn’t just dinner. It’s an invitation to savour the moment, linger over each bite, and make the evening feel just a little more extraordinary.I remain at your disposal.
