Breakfast Grilled Cheese

There are some weekend morning meals that just feel right. The smell of bacon sizzling in the pan, the rich aroma of coffee brewing, and the promise of a slow, satisfying start to the day. This Breakfast Grilled Cheese recipe is the embodiment of that feeling. It takes the humble grilled cheese, a source of comfort for many of us since childhood, and elevates it into a truly substantial morning meal. We’re talking golden, buttery sourdough, a generous amount of gloriously melty cheese, crisp, salty bacon, and the crowning glory: a perfectly fried egg with a jammy, golden yolk.
This isn’t just a sandwich; it’s a complete, well-rounded savory breakfast experience contained between two slices of bread. My kids absolutely devour this every time I make it, and honestly, so do I. It’s the kind of recipe that makes you look forward to waking up on a Saturday. It works beautifully for a lazy weekend brunch when you have a bit more time, or even for a hearty breakfast-for-dinner when you need something deeply comforting. It’s a straightforward recipe that delivers on its promise of a delicious, fulfilling meal every single time.
Recipe Overview
This Breakfast Grilled Cheese combines classic breakfast elements into one incredible sandwich. The flavour profile is rich and savory, with the sharpness of mature Cheddar balancing the salty, smoky bacon and the creamy richness of the egg yolk. The key is cooking it low and slow to achieve a perfectly crisp exterior while ensuring the cheese inside is completely melted and gooey. After testing this recipe five times, I finally got the cooking temperature just right to melt the cheese perfectly without burning the bread, which is the most common pitfall.

Why You’ll Love This Breakfast Grilled Cheese
- Genuine Flavour: The combination is a true classic for a reason. You get the tangy bite from a good quality mature Cheddar, which cuts through the salty richness of the smoked back bacon. This is all balanced by the creamy yolk of a free-range egg and held together by thick, chewy sourdough that’s been toasted to a beautiful golden-brown.
- Ready in Under 30 Minutes: From gathering your ingredients to plating up, this entire meal comes together in about 25 minutes, making it an ideal choice for a special breakfast that doesn’t consume your whole morning.
- Flexible Recipe: This recipe is a fantastic starting point. You can swap the bacon for sausage patties or slices of ham. Try different cheeses like Gruyère for a nutty flavour or Red Leicester for colour. You could even add a layer of caramelised onions for a touch of sweetness.
- Great for a Hearty Brunch: When you need a meal to power you through the day, this breakfast sandwich delivers. It’s substantial enough to be the star of a weekend brunch with friends or family. It also makes for a brilliant and satisfying lunch.
- Family Tested: This recipe always gets a thumbs-up from everyone at my table, from the youngest to the oldest. It’s one of those meals that brings a little bit of joy to the start of the day.
Ingredients You’ll Need
For the best results, using good quality ingredients makes all the difference here, especially the bread and cheese. I always opt for a proper bakery sourdough and a block of mature Cheddar that I grate myself. Pre-grated cheese often has coatings that prevent it from melting as smoothly.

- 4 thick slices of sourdough or other sturdy white bread
- 60g unsalted butter, softened (or see my tip below!)
- 150g mature Cheddar cheese, grated
- 6 rashers of smoked back bacon
- 2 large free-range eggs
- 1 tsp Dijon mustard (optional)
- Freshly ground black pepper
Marcus’s Tip: For an unbelievably crisp and evenly golden crust, use mayonnaise instead of butter on the outside of your bread. It sounds a bit unusual, but the oil and egg in mayonnaise give a fantastic finish. Just a thin, even layer is all you need. Give it a try; you might never go back to butter.
How to Make a Breakfast Grilled Cheese
The process is straightforward. We’ll cook the bacon first, then assemble the sandwich and toast it carefully while we fry the egg. The key is to manage your heat to ensure everything is ready at the same time.
- Cook the Bacon: Place a large, non-stick frying pan over a medium heat. Lay the bacon rashers in the cold pan and let them cook, turning occasionally, for 8-10 minutes or until they reach your desired level of crispiness. Remove the bacon to a plate lined with kitchen paper and set aside. Carefully wipe the excess fat from the pan.
- Prepare the Bread: Lay the four slices of sourdough on a chopping board. Spread the softened butter or mayonnaise evenly over one side of each slice. On the unbuttered side of two slices, spread the Dijon mustard, if using.
- Assemble the Sandwich: Flip the two mustard-spread slices over. Divide half of the grated cheese between them. Top with the cooked bacon rashers, breaking them if needed to fit. Sprinkle the remaining cheese over the bacon.
- Toast the Sandwich: Place the remaining two slices of bread on top, buttered-side-up. Carefully transfer the sandwiches to the frying pan over a medium-low heat. What works best for me is pressing down gently with a spatula for the first minute to ensure great contact with the pan and even browning.
- Cook Low and Slow: Cook the sandwiches for 4-5 minutes on the first side, until the bread is a deep golden brown. Carefully flip them over and cook for another 3-4 minutes on the other side, until golden and the cheese is completely melted and oozing.
- Fry the Eggs: While the second side is toasting, use a separate small pan to fry your eggs to your liking. A sunny-side-up egg with a runny yolk is traditional and adds a wonderful sauciness to the sandwich.
- Serve Immediately: Once the grilled cheese is ready, transfer it to a chopping board. You can either place the fried egg on top or gently open the sandwich and place it inside. Slice in half with a sharp knife and serve straight away while it’s hot and the cheese is stretchy.
Tips From My Kitchen
- Temperature Control: The single most important factor for a great grilled cheese is medium-low heat. If the heat is too high, the bread will burn long before the cheese has a chance to melt properly. Be patient; it’s worth it.
- The Secret Step: I mentioned it earlier, but using mayonnaise is a game-changer. I learned that the higher smoke point of the oil in mayo helps prevent burning, and the emulsifiers promote a beautifully even, crisp crust. For a deep dive into the science, Serious Eats has a great explanation.
- Make-Ahead: You can cook the bacon a day in advance and store it in an airtight container in the fridge. You can also grate your cheese ahead of time. This cuts the prep time down on the day you’re making them.
- Storage: A Breakfast Grilled Cheese is definitely best enjoyed fresh. If you do have leftovers, wrap them tightly in foil and store in the fridge for up to 24 hours. Reheat in a dry frying pan over a low heat until warmed through and crisp again.
Equipment You’ll Need
You don’t need any fancy gadgets for this recipe, just a few kitchen basics.
- Large non-stick frying pan
- A second small frying pan (for the egg)
- Spatula or fish slice
- Cheese grater
- Sharp knife
Common Mistakes to Avoid
- Using High Heat: As mentioned, this is the number one mistake. It leads to a sad sandwich with burnt bread and a solid block of cheese in the middle. Keep the heat low and give the cheese time to melt.
- Using the Wrong Bread: A standard thin-sliced sandwich loaf can become soggy and fall apart under the weight of the fillings. You need a sturdy bread like sourdough, ciabatta, or a thick-cut bloomer to provide the necessary structure.
- Overfilling the Sandwich: While it’s tempting to pile on the fillings, too much will make the sandwich difficult to flip and can lead to cheese oozing out and burning in the pan. Stick to the ratios in the recipe for a well-balanced result.
Delicious Variations to Try
Once you’ve mastered the basic recipe, feel free to get creative. This sandwich is a brilliant canvas for other flavours.
- Spicy Version: Add a few dashes of your favourite hot sauce with the cheese, or layer in some pickled jalapeño slices for a fiery kick. A spicy tomato chutney also works wonderfully.
- Vegetarian Option: Swap the bacon for pan-fried halloumi slices or a generous layer of sautéed mushrooms and spinach. Make sure to squeeze any excess water out of the spinach to avoid a soggy sandwich.
- Different Protein: Leftover cooked sausage patties, a few slices of good quality ham, or even some leftover Creamy Chicken would be fantastic in place of the bacon.
What to Serve With Your Breakfast Grilled Cheese
This is a hearty meal on its own, but a few simple accompaniments can round it out beautifully.
- A Simple Green Salad: A handful of rocket or watercress tossed with a sharp lemon vinaigrette helps to cut through the richness of the cheese and bacon.
- Classic Sauces: A dollop of tomato ketchup or brown sauce on the side is a must for many.
- A Strong Cup of Tea: Nothing complements a savoury British breakfast quite like a proper cup of tea. Freshly squeezed orange juice is also a great choice.
