Ingredients You’ll Need
Each ingredient for the Ultimate Breakfast Sandwich brings something special to the party; nothing fancy here, but together, they’re brilliant. From the smoky-salty bacon to the cooling crunch of arugula, every element amplifies taste and texture in the most gratifying way.
- Sourdough bread: Lightly toasting thick slices gives you the perfect crisp foundation and a tangy edge to balance the rich fillings.
- Mozzarella cheese: Melts beautifully, providing a creamy layer that hugs the warm eggs and savory meats.
- Tomato: Choose a ripe, medium tomato for juiciness and sweetness that cut through all the richness.
- Fresh arugula: Toss in a peppery bite with vibrant green color for both flavor and a visual pop.
- Red onion: Thinly sliced for just the right amount of zesty crunch and tangy contrast.
- Bacon: Crispy, smoky bacon slices deliver that irresistible savory crunch every sandwich craves.
- Mortadella: A luxe addition that adds depth and a velvet-smooth texture to each bite.
- Eggs (scrambled with milk): Make them soft and fluffy for the ultimate creamy center.
- Salt and black pepper: Season the eggs just right to enhance the sandwich’s flavor layers.
- Mayonnaise (optional): Adds a hint of tang and keeps everything extra moist, so slather if you love it.
How to Make Ultimate Breakfast Sandwich
Step 1: Toast the Sourdough
Start by lightly toasting your sourdough bread until golden and crisp. This creates a solid, crunchy base that holds up beautifully to all the juicy, melty goodness piled on top, and brings a delightful, subtle tang that sets the Ultimate Breakfast Sandwich apart.
Step 2: Scramble the Eggs
Whisk two eggs with a splash of milk, then scramble them gently in a nonstick pan over medium heat. Don’t rush—cook them slowly for the softest, fluffiest results. Season lightly with salt and black pepper to let the creamy eggs stand out among the bold flavors.
Step 3: Spread the Mayonnaise
If you’re a mayo enthusiast, this is your moment! Spread a thin layer of mayonnaise on one side of each toasted bread slice. It’s optional, but it adds a lovely tang and keeps the sandwich moist from the first to the last bite.
Step 4: Layer the Cheese and Veggies
Stack your mozzarella slices on one slice of bread, followed by juicy tomato, a generous heap of fresh arugula, and thin ribbons of red onion. These layers don’t just give your Ultimate Breakfast Sandwich vibrant color—they add cool crunch and garden-fresh flavor to balance the savory richness.
Step 5: Add the Meats
Lay the crispy bacon and two slices of silky mortadella over your veggies. The combination is hearty, deeply flavorful, and truly indulgent—just what you want in an early-morning treat.
Step 6: Pile on the Eggs and Finish
Spoon those fluffy, seasoned scrambled eggs over the stacked meats, then crown your creation with the second slice of bread. Press gently to anchor all the glorious layers, slice in half if you like, and get ready to savor every bite of the Ultimate Breakfast Sandwich.
How to Serve Ultimate Breakfast Sandwich

Garnishes
For a final flourish, try a sprinkle of flaky sea salt or a quick grind of fresh black pepper over your sandwich top. A few extra arugula leaves or a little drizzle of hot sauce can also dial up the color and zing. Remember, garnishes aren’t just for looks—they make the experience pop!
Side Dishes
The Ultimate Breakfast Sandwich has big, bold flavors, so pair it with sides that either complement or contrast. A citrusy fruit salad or crisp apple slices refresh the palate, while crunchy hash browns or a light green salad make it a heartier meal. And of course—don’t forget your favorite morning beverage.
Creative Ways to Present
Go cafe-style and wrap your sandwich in parchment paper for easy, on-the-go eating, or serve it open-faced for a rustic vibe. Cut it into triangles for a brunch platter, or stack halves on a skewer with fresh herbs for a wow-worthy brunch centerpiece. However you serve the Ultimate Breakfast Sandwich, make it Instagram-worthy!
Make Ahead and Storage
Storing Leftovers
While the Ultimate Breakfast Sandwich is best enjoyed fresh, you can absolutely save leftovers. Cool the assembled sandwich to room temperature, wrap tightly in foil or plastic wrap, and store in the fridge for up to 2 days. The flavors meld nicely, even if the bread loses a little crisp.
Freezing
If you want to make breakfast magic ahead of time, you can freeze the (uncut) assembled sandwich. Wrap it snugly in foil and then place it in an airtight freezer-safe bag. It will keep well for up to a month—just note that the veggies may soften a bit after thawing.
Reheating
To reheat, unwrap your sandwich and warm it gently in a toaster oven or regular oven at 350°F until hot, about 10 minutes. This method will help the sourdough regain its crispness, and the cheese gets oozy again. Microwaving is quick but will leave the bread softer and less crunchy.
FAQs
Can I use a different type of bread?
Absolutely! While sourdough gives the Ultimate Breakfast Sandwich its signature tang and structure, thick-cut whole wheat, ciabatta, or a brioche bun all work wonderfully. Just toast well for extra sturdiness.
What other cheeses can I substitute for mozzarella?
You can swap in provolone, Swiss, or even sharp cheddar for mozzarella if that’s what you have on hand. Soft cheeses melt best and pair perfectly with the fillings in your Ultimate Breakfast Sandwich.
Is there a vegetarian version?
Of course! Skip the bacon and mortadella, and ramp up the veggies with roasted red peppers, sautéed mushrooms, or avocado. The sandwich will still be bursting with flavor and texture.
Can I make Ultimate Breakfast Sandwich ahead for meal prep?
Yes! Prep all your sandwich components ahead (toast, scramble, cook), let them cool, then assemble and wrap your sandwiches for the week. Store in the fridge or freezer as described above, reheating as needed.
What’s the best way to keep the sandwich from getting soggy?
Be mindful of using ripe but not overly juicy tomatoes, and place cheese under the eggs and meats to create a moisture barrier. Toasting the bread well also helps keep your Ultimate Breakfast Sandwich perfectly crisp.
