Glamorgan Sausage Recipe: Welsh Veggie Sausages

Glamorgan sausage is a traditional Welsh vegetarian sausage made from cheese, leeks, and breadcrumbs, bound with egg and shaped into cylinders before being fried until golden. It is a satisfying, savory dish that works beautifully as a main with mashed potatoes and gravy or as a party snack. The combination of tangy cheese, sweet leeks, and crisp breadcrumb coating delivers a hearty texture and flavor that even meat-eaters will enjoy.

Ingredients

2 large leeks (about 1 lb / 450 g), white and light green parts only
2 tbsp (30 g) unsalted butter
2 cups (100 g) fresh breadcrumbs (from about 3 slices of bread)
1 1/2 cups (170 g) grated mature cheddar cheese (or Caerphilly)
1 tsp (5 g) dry mustard powder
1/2 tsp salt
1/4 tsp black pepper
2 large eggs, beaten
1/2 cup (60 g) fine dry breadcrumbs (for coating)
2 tbsp (30 ml) vegetable oil, for frying

Instructions

Slice the leeks in half lengthwise, rinse well to remove grit, and thinly slice crosswise. You should have about 2 cups (200 g).
Melt the butter in a skillet over medium heat. Add the leeks and cook, stirring, for 8–10 minutes until soft and translucent but not browned. Remove from heat and let cool for 5 minutes.
In a large bowl, combine the fresh breadcrumbs, grated cheese, mustard powder, salt, and pepper. Add the cooked leeks and mix well.
Pour in the beaten eggs and stir until the mixture holds together when pressed. If it seems too dry, add a splash of milk; if too wet, add more breadcrumbs.
Shape the mixture into 8 equal cylinders, about 3 inches (7.5 cm) long and 1 inch (2.5 cm) thick. Press firmly so they hold their shape.
Place the fine dry breadcrumbs in a shallow dish. Roll each sausage in the breadcrumbs to coat evenly, pressing gently to adhere.
Heat the oil in a large non-stick skillet over medium heat. Cook the sausages in batches, without crowding, for 3–4 minutes per side, turning carefully, until golden brown and heated through. The internal temperature should reach 160°F (71°C) (USDA FSIS safe minimum for egg dishes) if checked with a food thermometer.
Drain on paper towels and serve hot.

Tips

Use a mature (sharp) cheddar or traditional Caerphilly cheese for the best flavor. A mild cheese will make the sausages bland.
Make sure the leeks are well-drained after cooking; excess moisture will make the mixture too soft to shape.
Chilling the shaped sausages for 15 minutes before coating helps them hold together during frying.
If you don’t have fresh breadcrumbs, you can make them by pulsing stale bread in a food processor. Avoid using the fine dry ones for the mixture—they will make it too dense.

Serving Suggestions

Serve the Glamorgan sausages with creamy mashed potatoes, a rich onion gravy, and steamed green vegetables like peas or broccoli. For a lighter meal, tuck them into a warm baguette with salad and a dollop of chutney, or serve them as part of a traditional Welsh breakfast with fried eggs and mushrooms.

Variations

Add 1/2 teaspoon of smoked paprika or a pinch of cayenne pepper to the mixture for a smoky or spicy kick.
Swap the leeks for finely chopped spring onions (scallions) or a mixture of leek and onion.
Use a vegetarian hard cheese like a mature Gouda or Gruyère in place of cheddar for a different flavor.
For a gluten-free version, use gluten-free breadcrumbs and ensure your mustard powder is gluten-free.

Storage and Reheating

Refrigerate cooked Glamorgan sausages in an airtight container for up to 3 days. To reheat, place them on a baking sheet in a 350°F (175°C) oven for 10–12 minutes, or until piping hot (165°F / 74°C). They can also be reheated in a skillet over medium heat for 3–4 minutes per side, but the coating may soften. Freeze uncooked sausages on a tray, then transfer to a freezer bag for up to 2 months. Thaw overnight in the refrigerator before frying.

Frequently Asked Questions

Can I bake the sausages instead of frying? Yes, you can bake them at 400°F (200°C) for 15–18 minutes, turning once, until golden and hot throughout. They will be less crispy than fried, but still delicious.

What is the traditional cheese for Glamorgan sausage? The original recipe uses Caerphilly cheese, a crumbly Welsh cheese. Mature cheddar is a common and excellent substitute that is easier to find.

Why did my sausages fall apart during cooking? This usually happens if the mixture is too wet. Make sure the leeks are well-cooked and drained, and chill the shaped sausages before coating. If the mixture is too soft, add more breadcrumbs.

Can I make the mixture ahead of time? Yes, you can prepare the mixture up to a day in advance, cover, and refrigerate. Shape and cook when ready. The mixture may become a bit sticky; just add a little more breadcrumbs if needed.

Are Glamorgan sausages suitable for vegans? The traditional recipe contains eggs and cheese, so it is not vegan. However, you can make a vegan version using crumbled firm tofu, nutritional yeast, and a flax egg, though the texture will differ.

What can I use instead of leeks? If leeks are unavailable, use a large yellow onion, finely chopped and cooked until soft, or a combination of onion and celery for a similar mild flavor.
