Introduction

The patty melt toastie is a delicious fusion of a burger and grilled cheese sandwich, delivering rich, savory flavors with melted cheese and caramelised onions. This recipe offers a comforting twist on a classic American diner favorite, perfect for a satisfying meal any time.

The image shows two white plates on a white marbled surface with a purple cloth underneath. The plate in the front has a toasted sandwich with two layers of golden brown bread. Between the bread, there is melted cheese that is creamy yellow and oozing out with some crispy browned bits at the edges, and some browned crispy onions. The plate in the back holds a sandwich cut in half with the same toasted bread and melted cheese, but in between, there is also a visible thick layer of cooked ground meat. The cut side shows a bit of stringy melted cheese and browned caramelized onions. Next to this plate is a knife with some crumbs on it. There is also a white bowl filled with pickle slices and some other pickled vegetables on the left side. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

3 tbsp butter
2 tbsp olive oil
1 large onion, finely sliced
200g beef mince
½ tsp garlic granules
2 tsp Worcestershire sauce
4 slices bloomer loaf or white bread
100g mature cheddar, grated
100g Swiss cheese, grated
2 tsp Dijon mustard

Instructions

Step 1: Heat 1 tbsp butter and half the olive oil in a large heavy-based frying pan over medium heat. Add the sliced onion with a pinch of salt and cook gently for 20–25 minutes until the onion is golden and sticky.
Step 2: In a bowl, combine the beef mince with garlic granules, Worcestershire sauce, and seasoning. Mix well with your hands until the mince reaches a fine texture. Divide into two balls and flatten into patties matching the bread shape.
Step 3: Remove the caramelised onions from the pan and set aside. Increase the heat to high and heat the remaining olive oil. Fry the patties for 3–4 minutes on each side until golden brown and cooked through. Transfer to a plate, spooning any browned bits from the pan over them.
Step 4: Reduce the heat to medium-low. Melt ½ tbsp butter in the pan and toast the bread slices on one side in two batches, pressing them down evenly until golden and crisp. Add another ½ tbsp butter for the second batch. Mix the cheddar and Swiss cheese together in a bowl.
Step 5: Place two bread slices toasted-side up on a board and spread each with Dijon mustard. Sprinkle half the cheese on each slice, add a spoonful of caramelised onions, then top with a cooked burger patty. Scatter the rest of the cheese over the patties and cover with the remaining bread slices, toasted-side down.
Step 6: Heat most of the remaining butter in the pan and fry the sandwiches for 2–3 minutes, pressing down constantly until golden and toasted. Flip carefully, add the final butter to the pan around the sandwiches, and cook until the cheese melts and both sides are golden and crisp.

Tips & Variations

For a spicy twist, add a spoonful of gochujang and sesame seeds to the cheese mixture and layer the sandwich with kimchi and spring onions instead of caramelised onions.
To create a Reuben-style patty melt, replace the burger patties with pastrami or thick slices of salt beef, add sauerkraut with the onions, and include sliced pickled gherkins for extra flavor.
Using sourdough or rye bread instead of bloomer adds a lovely depth and texture to the toastie.
Pressing the sandwich down firmly while cooking ensures even toasting and a great crust.

Storage

Store leftover patty melt toasties in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet over low heat to crisp the bread while warming the filling, or use a toaster oven. Avoid microwaving as it can make the bread soggy.

How to Serve

The image shows two white plates on a white marbled surface with two grilled sandwiches. The sandwich on the plate in the front has two golden-brown toasted bread slices with melted, gooey cheese dripping slightly out of the edges and crispy fried onions inside. The second plate in the background holds a sandwich cut diagonally in half, showing layers with gooey white melted cheese, a thick beef patty, crispy fried onions, and a piece of crispy bacon. A knife rests on the edge of this plate. Nearby, there is a small bowl with thick pickle slices and some yellow cabbage. The overall colors include warm golden browns of the toasted bread and melted cheese with contrasting greenish-yellow pickles. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use different types of cheese?

Yes, feel free to substitute cheddar or Swiss with other melting cheeses like mozzarella or gruyère. Combining cheeses adds depth to the flavor and texture.

Can I prepare the patties in advance?

Absolutely. You can shape the patties ahead of time and refrigerate them for up to 24 hours before cooking. This makes assembling the toasties quicker.
