Ingredients needed
- Bread - We went with some sliced sourdough. You want something sturdy as these sandwiches are pretty packed out and need some stable bread.
- Eggs - Use fresh eggs. We like using ones with golden yolks as that makes the omelette look nice and vibrant.
- Milk - Just a little splash of whole milk to make the omelette.
- Cheese - We added some matura cheddar to the omelette, as it has a strong flavour and a little goes a long way.
- Spinach - An easy way to give a vegetable boost to the omelette. You could swap it for kale if you prefer.
- Bacon - We used smoked bacon. You could swap it for turkey bacon if you wanted to make it a little lighter.
- Tomato - Use large beef tomatoes. Make sure they are super ripe for the best flavour.
- Avocado - A fresh and ripe avocado adds a lovely creaminess to these sandwiches.
- Oil - A little olive oil to cook the eggs in.
- Sauce - We went with ketchup, but we have given some other sauce options below.
A full ingredients list with measurements is in the recipe card below.
How to make a breakfast sandwich - Step by step
One: Mash the avocado and set aside.
Two: Whisk the eggs with the milk and then stir in the cheese and spinach.
Three: Heat a little oil in a frying pan and add the egg. Gently cook for about 3-4 minutes until the egg is cooked. Fold in half and then slice into two.
Four: Put the bacon under the grill and cook for 2-3 minutes each side.
Five: Assemble the sandwiches by toasting the bread. Spread the mashed avocado over 2 of the slices of bread and add the tomato. Top with the cooked egg.
Six: Add bacon then drizzle ketchup over the other slice of bread.
What is a breakfast sandwich?
"The Ultimate" is a bit of a bold statement. But we think these sandwiches have everything! They are a protein packed way to start your day and we have even snuck some veggies in there by adding shredded spinach to the omelette.
A breakfast sandwich is basically two slices of bread, with all your favourite breakfast ingredients in between them. We have given you lots of ways you can adapt this recipe below.
Variations
You can really go wild when it comes to customising this sandwich. Use our recipe as a base, and then switch and swap for all your favourites.
Bread - Whilst it is all about the fillings, the bread is just as important as it holds the sandwich together. We went with a couple of slices of sourdough, but there are so many options here. You could use an English muffin or a homemade bagel, a soft roll or even a croissant for something extra fancy. We found two slices of bread were the most stable though. Why not try our Easy White Bread Recipe.
Eggs - We have gone for a spinach omelette, but if that isn't your thing you could add a fried or poached egg.
Meat - You could swap the bacon for sausages (and even use veggies sausages to keep it vegetarian). Some really good quality ham will work well too. You can leave the avocado out (but we don't recommend that) and even add some roasted peppers for sweetness.
Cheese - We didn't add any extra cheese, because there is already some in the omelette. But you could leave it out of the eggs and then add a slice of cheese when stacking up the sandwich so it goes all melty and gooey. You could always then pop it under the grill for a breakfast grilled cheese.
Sauce - What is a sandwich without sauce? I wouldn't know, as I put sauce on everything! We kept this recipe classic and used our Homemade Healthy Tomato Ketchup, but you don't have to limit yourself to that.
You could add our Homemade Healthy BBQ Sauce or some chilli sauce or pesto would work too. Even salsa would be a good way to go, especially with the mashed avocado. So many options! We are big fans of hot sauce too, so a drizzle of Sriracha would go well.
Storage
Store: These are best eaten fresh, so only make as many as you need. However, if you have any leftover then you can freeze them using the directions below.
Freeze: These sandwiches are great for batch cooking at the weekend and then freezing for easy weekday breakfasts on the go. The only thing we would suggest is to leave the avocado and tomatoes out and then add them fresh once defrosted. Wrap the sandwiches individually in some baking paper and then put them in a freezer bag.
Defrost: Defrost them in the fridge overnight.
Reheat: Once fully defrosted, you can heat them under the grill or in the microwave.
Extra tips
- You can either use slices of bread from a loaf, or make this with English muffins, bagels or croissants.
- We mixed cheese in to the omelette, however you could skip that and add a slice of cheese when stacking up the sandwich.
- You can freeze these sandwiches, but we would recommend leaving out the mashed avocado and tomato and adding them fresh before eating.
- Make these vegetarian by swapping the bacon for cooked vegetarian sausages.
- If you want some extra crunch in your breakfast sandwich, then add some finely sliced red onions.

Cheese and egg in a sandwich? Sounds good to me!
What kind of bread do you usually eat? I tried to cut down on bread, but I just couldn't do it. I love it too much. So I was wondering what the best choice was.

Grilled cheese sandwiches remind me of being a kid too. My mum would always make us one on a Sunday morning. Thanks for the reminder :)
