Ingredients
Method
- Melt 2 tbsp butter in a saucepan over medium heat. Cook onion until soft, 5 minutes. Stir in garlic for 30 seconds. Sprinkle flour over top and stir 1 minute.
- Slowly whisk in warm milk and cook, stirring, until thickened, 3–4 minutes. Remove from heat and stir in 1 cup cheddar, salt, pepper, and mustard powder.
- Toss shredded cabbage with the cheese sauce in a large bowl until evenly coated.
- Transfer to a 9x13-inch baking dish. Mix panko, remaining ½ cup cheddar, and melted butter; scatter over the top.
- Bake at 375°F (190°C) for 30–35 minutes until golden and bubbling. Let rest 5 minutes, garnish with parsley, and serve.
Notes
Resting the baked casserole for a few minutes makes it easier to serve and lets the sauce thicken. If you like extra crunch, pop it under the broiler for the final two minutes, but keep a close eye so the breadcrumbs don’t scorch.
