These Spanish-style vegetarian croquettes feature earthy mushrooms folded into a creamy béchamel with manchego cheese, then coated and fried until golden. The result is a crisp shell with a rich, velvety filling. Perfect for tapas, appetisers, or a meat-free meal that feels indulgent yet comforting.
Start by heating olive oil in a large pan and cooking the shallot and garlic until soft. Add the mushrooms and cook over medium heat until all the liquid has evaporated and they’re beginning to brown. Season lightly and set aside.
In a separate saucepan, melt the butter and stir in the flour to make a smooth paste. Cook for a minute before gradually adding warm milk, whisking until you have a thick, glossy béchamel. Stir in the mushroom mixture and grated cheese, along with nutmeg, salt, and pepper. Mix until everything is well blended.
Spread the mixture into a shallow dish, drizzle with a touch of oil, and leave to cool completely before chilling for several hours. When firm, shape into small ovals or balls, coat in flour, egg, and breadcrumbs, and chill again for 30 minutes. Fry at 180°C for 2 to 3 minutes until golden.
Notes
Use fresh mushrooms, not the watery kind that come pre-sliced in plastic tubs. Slice or chop them evenly so they cook at the same pace. A bit of shallot adds sweetness that balances the savoury mushrooms, and garlic brings out their depth.I prefer manchego for its nutty tang, but cheddar or even mozzarella works if that’s what you have. The cheese should melt easily into the sauce, giving the mixture its creamy, slightly elastic texture when you bite in.
