Glamorgan Sausage Hot Dog: Welsh Veggie Recipe

The Glamorgan sausage is a Welsh classic: a vegetarian sausage made with Caerphilly cheese, leeks, and breadcrumbs, traditionally shaped and fried. Turning it into a hot dog is a brilliant mash-up—the crispy, cheesy sausage gets all the classic hot dog toppings, but with a far more interesting flavor. It works because the mild, tangy cheese and sweet leeks pair beautifully with mustard and pickles, making a hearty, satisfying meal that even meat-eaters will love.

Ingredients

2 large leeks (about 200 g / 7 oz), white and light green parts only, finely chopped
2 tbsp (28 g) butter or olive oil
2 cups (100 g) fresh breadcrumbs (from about 3 slices of bread)
1 1/2 cups (170 g) grated Caerphilly cheese (or substitute with mature cheddar or a vegetarian sharp white cheddar)
1 tsp dry mustard powder
1/2 tsp salt
1/4 tsp black pepper
2 large eggs, beaten
1/2 cup (60 g) all-purpose flour, for coating
1 cup (100 g) additional breadcrumbs, for coating
Vegetable oil, for frying (about 1/2 cup / 120 ml)
4 hot dog buns
Your favorite hot dog toppings: yellow mustard, ketchup, relish, sauerkraut, or pickled onions

Instructions

In a skillet over medium heat, melt the butter or heat the olive oil. Add the chopped leeks and cook, stirring occasionally, until soft and translucent, about 5-7 minutes. Remove from heat and let cool slightly.
In a large bowl, combine the cooked leeks, 2 cups (100 g) breadcrumbs, grated cheese, mustard powder, salt, and pepper. Mix well.
Add the beaten eggs to the mixture and stir until everything is moistened and holds together when pressed. If the mixture seems too dry, add a teaspoon of milk or water; if too wet, add a bit more breadcrumbs.
Divide the mixture into 4 equal portions. With lightly floured hands, shape each portion into a sausage shape about 4-5 inches (10-12 cm) long and 1 inch (2.5 cm) thick.
Place the flour, the extra 1 cup (100 g) breadcrumbs, and a beaten egg (if needed for coating) in three separate shallow bowls. (You may need one more egg for coating; beat it in a small bowl.)
Roll each sausage in the flour, then dip in the beaten egg, then roll in the breadcrumbs, pressing gently to adhere. Place on a plate and refrigerate for 15 minutes to firm up.
In a large skillet, heat about 1/2 inch (1 cm) of vegetable oil over medium heat. When a breadcrumb sizzles when dropped in, the oil is ready.
Fry the sausages in batches, turning occasionally, until golden brown and crisp on all sides, about 4-5 minutes per batch. Do not crowd the pan. Drain on paper towels.
Warm the hot dog buns in a toaster or in a dry skillet for 1-2 minutes.
Place a Glamorgan sausage in each bun and top with your desired toppings. Serve immediately.

Tips

Cheese substitution: Caerphilly is traditional, but it can be hard to find. A good mature cheddar or a vegetarian sharp white cheddar works well. Avoid very soft cheeses like mozzarella, as they will make the mixture too sticky.
Breadcrumbs: Fresh breadcrumbs are essential for a light texture. If you only have dried, use 1 1/2 cups (75 g) dried and add a little extra egg if the mixture is too dry.
Chilling is key: Don’t skip the 15-minute chill before frying. It helps the sausages hold their shape and prevents them from falling apart in the oil.
Frying temperature: If the oil is too hot, the outside will burn before the inside is heated through. If too cool, the sausages will absorb oil and become greasy. Keep the oil at a steady medium heat.

Serving Suggestions

Serve these hot dogs with a side of crispy fries, a simple green salad, or some pickled vegetables. They are also great with a cold beer or a glass of cider. For a full Welsh spread, add a side of laverbread (if you can find it) or some roasted potatoes.

Variations

Spicy version: Add 1/2 teaspoon of smoked paprika or a pinch of cayenne pepper to the mixture for a smoky kick.
Herb version: Stir in 2 tablespoons of chopped fresh parsley, chives, or thyme.
Baked version: To make them lighter, bake the coated sausages on a parchment-lined baking sheet at 400°F (200°C) for 20-25 minutes, turning halfway, until golden and crisp. They won’t be as crunchy as fried, but they are still delicious.
Vegan option: Use a vegan cheese that melts well, replace the eggs with a flax egg (1 tbsp ground flaxseed mixed with 3 tbsp water per egg), and use vegan butter and breadcrumbs. Coat with a mixture of plant milk and flour instead of egg.

Storage and Reheating

Cooked Glamorgan sausages can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, place them on a baking sheet and warm in a 350°F (175°C) oven for 10-15 minutes, or until heated through and crisp again. You can also reheat in a skillet with a little oil over medium heat for about 5 minutes, turning occasionally. They are not recommended for reheating in the microwave, as they will become soggy.

Frequently Asked Questions

Can I make the mixture ahead of time? Yes, you can prepare the mixture and shape the sausages up to 24 hours in advance. Keep them covered in the refrigerator, then coat and fry just before serving.

What is Caerphilly cheese and where can I find it? Caerphilly is a crumbly, slightly tangy white cheese from Wales. It is available in many specialty cheese shops and some larger supermarkets. If you can’t find it, a good mature cheddar is the best substitute.

Can I freeze them? Yes, you can freeze the uncooked, coated sausages. Place them on a baking sheet in the freezer until solid, then transfer to a freezer bag. They will keep for up to 2 months. Fry from frozen, adding a few extra minutes to the cooking time.

Why did my sausages fall apart in the pan? This usually happens if the mixture is too dry or too wet, or if the oil is not hot enough. Make sure the mixture holds together when pressed, and that the oil is at the right temperature before adding the sausages. Chilling them well before frying also helps.

Are these suitable for vegetarians? Yes, as long as you use a vegetarian cheese (some cheeses contain animal rennet) and ensure your breadcrumbs are vegetarian (some contain L-cysteine). Check the labels to be sure.

Can I grill them instead of frying? Yes, you can grill them on a barbecue or under a broiler. Brush them lightly with oil and cook over medium heat, turning frequently, until heated through and browned, about 10-12 minutes. They may be less crisp than fried, but they will have a smoky flavor.
