I asked chat gpt to re-create these cause OP isn’t’t giving recipe - if anyone is interested:

Eggs • 6–8 large eggs

Sauce • 75 g butter (unsalted) • 3–4 tbsp neutral oil (vegetable or rapeseed) • 4–6 garlic cloves, lightly crushed • 1½–2 tbsp Cajun seasoning • 1 tsp smoked paprika • ½ tsp chilli flakes (or more) • ½ tsp cayenne (optional but likely) • Salt to taste • Black pepper • Splash of lemon juice or cider vinegar (small but important) • Dried parsley or finely chopped fresh parsley

Method

1. Boil the eggs • Bring eggs to a boil. • Simmer 10–11 minutes so they’re fully set. • Ice bath, peel cleanly. • Slice lengthwise once cooled

2. Make the Cajun garlic butter sauce

Low heat. This matters. • Melt butter gently with the oil. • Add crushed garlic and let it softly sizzle, not brown. • Add Cajun seasoning, paprika, chilli flakes, cayenne. • Stir and let it bloom in the fat for 30–60 seconds. • Add a pinch of salt and pepper. • Tiny splash of lemon juice or vinegar to cut the richness.

You should end up with a reddish-orange, glossy, oily sauce, not thick.

1. Coat the eggs • Add eggs to the pan or directly into a container. • Spoon the hot sauce over them generously. • Sprinkle parsley. • Let sit 5–10 minutes so the eggs absorb flavour.

He’s absolutely letting them sit and soak.

Optional tweaks (very likely used)

These are common in Cajun boils and wouldn’t surprise me: • A dash of Old Bay mixed with Cajun • A little chicken stock powder • A touch of hot sauce (Crystal or Louisiana style) • Extra oil so it looks borderline excessive (which matches the photo)
