The Dunkin’ Sourdough Breakfast Sandwich is one of the most popular morning menu items at Dunkin’ Donuts, offering a satisfying combination of crispy, buttery sourdough bread, savory proteins, and melted cheese. It’s a hearty and flavorful breakfast option that has gained a loyal following among Dunkin’ fans.

A Closer Look at the Ingredients

This sandwich is made with:

• Sourdough Bread – Unlike regular sandwich bread, sourdough has a tangy flavor and a crisp, airy texture when toasted. Its slightly chewy bite makes it the perfect base for holding all the delicious ingredients together.
• Egg – A fluffy, perfectly cooked egg adds richness and balances the savory flavors of the sandwich.
• Cheddar Cheese – The sharp, creamy taste of melted cheddar cheese enhances every bite, creating a satisfying melt-in-your-mouth experience.
• Sausage or Smoked Bacon – Dunkin’ offers two protein choices: a juicy, seasoned sausage patty or crispy smoked bacon, both adding a bold, savory element.
• Butter and Seasoning – The sandwich is toasted with butter for added crispness and a deep, rich flavor. Some locations also offer seasoning or sauce for extra taste.

Why It’s a Fan-Favorite Breakfast Choice

• Perfect Balance of Crunch and Softness – The contrast between the crisp sourdough bread and the soft egg, cheese, and meat makes every bite enjoyable.
• Hearty and Filling – This sandwich is packed with protein and healthy fats, making it an excellent choice for a satisfying breakfast that keeps you full for hours.
• Pairs Well with Coffee – Many Dunkin’ fans love pairing this sandwich with their favorite Dunkin’ coffee, such as iced lattes or hot brewed coffee, for a complete breakfast experience.

How It Compares to Other Breakfast Sandwiches

While many fast-food restaurants offer breakfast sandwiches, the Dunkin’ Sourdough Breakfast Sandwich stands out for its use of sourdough bread, which provides a more artisanal, homemade feel compared to traditional white bread or English muffins. It’s a great alternative to classic options like McDonald’s Egg McMuffin or Starbucks’ breakfast sandwiches, offering a unique, flavorful twist on the classic breakfast sandwich.

If you’ve never tried it before, this sandwich is definitely worth a taste! But if you’d rather enjoy it fresh from your own kitchen, keep reading to learn how to make a homemade version that’s just as delicious—if not better—than the original.

Ingredients You Need for a Homemade Version

Making a Dunkin’ Sourdough Breakfast Sandwich at home is easier than you might think! By using high-quality ingredients and a few simple cooking techniques, you can recreate this delicious breakfast favorite in your own kitchen. Below are the key ingredients you’ll need to make the best homemade version of this Dunkin’ copycat sandwich.

1. Sourdough Bread – The Perfect Base

The key to achieving that signature taste and texture is using sourdough bread, which has a slightly tangy flavor and a light, chewy interior. Unlike standard sandwich bread, sourdough toasts beautifully to a golden crisp while still remaining soft inside.

Sourdough isn’t just delicious—it also offers health benefits! It contains natural probiotics, is easier to digest than regular bread, and has a lower glycemic index. Learn more about the health benefits of sourdough bread from a dietitian’s perspective.

Pro Tip: Choose a fresh bakery-style sourdough loaf for the best flavor and texture. Slice it thick enough to hold all the ingredients without getting soggy.

2. Egg, Cheese & Meat – The Essential Fillings

The heart of the sandwich is its protein-packed filling, which includes a perfectly cooked egg, gooey melted cheese, and a savory meat option.

• Egg – A fluffy fried or scrambled egg gives the sandwich richness and moisture. If you want an authentic Dunkin’ style, cook the egg in a round mold for a neat, restaurant-quality appearance.
• Cheddar Cheese – Dunkin’ uses a slice of white cheddar cheese, which melts smoothly and complements the tangy sourdough. You can also substitute American cheese for extra creaminess or Swiss cheese for a milder, nuttier flavor.
• Meat Options:
  • Sausage Patty – A seasoned, juicy sausage patty is the classic choice for a heartier sandwich.
  • Smoked Bacon – Crispy, flavorful bacon adds a salty, smoky touch.
  • Turkey or Plant-Based Sausage (Optional) – For a healthier twist, you can use lean turkey sausage or a vegetarian alternative.

Pro Tip: Pre-cook your bacon or sausage before assembling the sandwich to get that perfectly crisp texture without making the bread soggy.

3. Extras for More Flavor

To elevate your DIY Dunkin’ Sourdough Breakfast Sandwich, consider adding a few extras for even more deliciousness:

• Butter – Spreading a thin layer of butter on the sourdough before toasting helps achieve a golden, crispy texture.
• Seasoning – A dash of salt, pepper, or even garlic powder can enhance the flavors.
• Optional Sauces – While Dunkin’s version doesn’t come with sauce, you can customize your homemade sandwich with a spread of:
  • Spicy Sriracha Mayo – For a kick of heat.
  • Honey Mustard – Adds a sweet-savory contrast.
  • Avocado Spread – For a creamy, nutrient-packed boost.

How to Make a Dunkin’ Sourdough Breakfast Sandwich at Home

Now that you have all your ingredients ready, it’s time to put everything together and recreate the Dunkin’ Sourdough Breakfast Sandwich in your own kitchen. This homemade version is easy to make and delivers the same delicious, crispy, and savory flavors you love from Dunkin’ Donuts. Follow these step-by-step instructions to achieve the perfect breakfast sandwich every time!

Step 1: Toast the Sourdough Bread to Perfection

The foundation of this sandwich is crispy, golden-brown sourdough bread, which provides the perfect balance of crunch and chewiness.

How to Toast the Bread:

• Lightly butter both sides of the sourdough slices for extra flavor and crispness.
• Heat a non-stick skillet or griddle over medium heat.
• Place the buttered slices face down in the skillet and toast for about 2-3 minutes per side, or until golden brown.
• Remove from heat and set aside.

Pro Tip: If you prefer a crispier texture, you can also toast the sourdough in a toaster oven or air fryer at 375°F (190°C) for 3-5 minutes.

Step 2: Cook the Egg & Meat

The egg and protein are the heart of this sandwich, adding rich flavor and a satisfying bite.

Cooking the Egg:

• Heat a small amount of butter or oil in a non-stick pan over medium heat.
• Crack an egg into a round egg mold (or a mason jar lid) to keep it in the perfect shape.
• Cook for 2-3 minutes until the egg white is set but the yolk remains slightly runny (or cook longer if you prefer a firmer yolk).
• Season with salt and pepper, then set aside.

Pro Tip: For a scrambled version, whisk the egg with a splash of milk before cooking to create a fluffy texture.

Preparing the Protein (Sausage or Bacon):

• For Sausage: Cook a breakfast sausage patty in the same pan over medium heat for 3-4 minutes per side, or until browned and fully cooked.
• For Bacon: Cook smoked bacon strips until crispy, about 4-5 minutes, then drain on a paper towel.

Healthier Option: Use turkey sausage or a plant-based sausage patty for a leaner alternative.

Step 3: Assemble the Sandwich

Now comes the fun part—putting everything together!

How to Assemble:

1. Start with one toasted sourdough slice as the base.
2. Add the cooked sausage patty or crispy bacon on top.
3. Place the fried egg over the meat.
4. Top with a slice of cheddar cheese to let it melt slightly from the heat.
5. Finish with the second slice of toasted sourdough to complete the sandwich.

Pro Tip: If you want the cheese to melt more, you can place the assembled sandwich back in the pan for 30 seconds per side, covering it with a lid.

Step 4: Customize Your Sandwich (Optional Enhancements)

Want to take your homemade Dunkin’ Sourdough Breakfast Sandwich to the next level? Try these delicious customizations:

• Add a Sauce: Spread some sriracha mayo, honey mustard, or garlic aioli on the bread for extra flavor.
• Make It Healthier: Use egg whites, turkey bacon, or avocado for a nutritious twist.
• Extra Toppings: Add sautéed onions, spinach, or a slice of tomato for more freshness.

Tips to Make the Best Breakfast Sandwich

Creating a homemade Dunkin’ Sourdough Breakfast Sandwich is easy, but with a few extra tips and tricks, you can take it from good to absolutely amazing! Here’s how to ensure your breakfast sandwich is crispy, flavorful, and perfectly balanced every time.

1. Use Fresh, High-Quality Ingredients

The quality of your ingredients plays a huge role in the taste and texture of your sandwich.

• Sourdough Bread – Opt for a fresh, bakery-style sourdough loaf rather than pre-packaged slices. A thick-cut sourdough will hold up better to the fillings.
• Eggs – Pasture-raised or organic eggs tend to have richer yolks and better flavor.
• Cheese – Sharp white cheddar is closest to Dunkin’s version, but you can also try pepper jack for spice or Swiss for a milder taste.
• Meat – Use high-quality sausage or thick-cut smoked bacon for the best flavor. If using store-bought sausage patties, look for options with minimal additives.

Pro Tip: If you love extra crunch, toast your sourdough in a pan with a little butter rather than in a toaster—it adds more flavor!

2. Cook Everything at the Right Temperature

Cooking your ingredients properly is key to getting the perfect textures in your sandwich.

• Eggs – Cook your egg over medium-low heat to prevent overcooking. For a soft, creamy yolk, remove it from the pan while it’s slightly underdone, as it will continue cooking from residual heat.
• Meat – Whether using sausage or bacon, cook it over medium heat to get a crispy, golden-brown finish without drying it out.
• Bread – If using butter, toast your sourdough on medium heat so it crisps up without burning.

Pro Tip: If you want your cheese to melt perfectly, place it on the egg while still in the pan, then cover with a lid for 30 seconds.

3. Customize the Sandwich to Your Taste

One of the best things about making this sandwich at home is the ability to customize it to your preferences!

Protein Variations:

• Swap sausage for crispy bacon or turkey sausage for a leaner option.
• Try plant-based sausage patties for a vegetarian-friendly version.
• Use grilled chicken or ham if you want something different from traditional breakfast meats.

Topping Ideas:

• Avocado slices – Add creaminess and healthy fats.
• Tomato & spinach – Bring freshness and extra nutrients.
• Caramelized onions – Add a touch of sweetness and depth of flavor.
• Pickled jalapeños – A great way to add some heat!

Sauce Enhancements:

Dunkin’s original sandwich doesn’t include sauce, but adding a flavorful spread can take it to the next level. Here are some delicious options:

• Spicy sriracha mayo – If you love a little heat.
• Honey mustard – A sweet-savory combination that pairs well with sausage.
• Garlic aioli – A rich, garlicky spread for extra depth.
• Maple butter – A perfect mix of sweet and savory!

Pro Tip: Lightly spread your chosen sauce on the toasted sourdough before assembling for the best flavor distribution.

4. Pair It With the Perfect Drink

A great breakfast sandwich deserves an equally amazing drink pairing!

• Classic Hot Coffee – A smooth, medium-roast coffee complements the rich flavors of the sandwich.
• Iced Latte – Dunkin’ fans love pairing this sandwich with an iced caramel or vanilla latte.
• Cold Brew with Sweet Cream – For a bold yet slightly sweet pairing.
• Fresh Orange Juice – If you prefer a non-coffee option, fresh juice provides a refreshing contrast to the richness of the sandwich.

Pro Tip: If you’re making a coffeehouse-style breakfast at home, brew your own Dunkin’ Donuts coffee blend to get the full experience!

5. Meal Prep for a Quick Breakfast on Busy Mornings

Want to enjoy this sandwich without cooking every morning? You can prep ingredients ahead of time for a grab-and-go breakfast!

Make-Ahead Tips:

• Pre-cook the sausage or bacon and store it in the fridge for up to 3 days.
• Toast the sourdough ahead of time and store it in an airtight container.
• Fry the eggs in advance and reheat them in a skillet for 30 seconds before assembling.

Freezing for Later:

• Assemble the sandwich without toasting the bread, then wrap it in foil or parchment paper.
• Freeze for up to 1 month.
• To reheat, unwrap and microwave for 1-2 minutes, then toast the bread separately for freshness.

Pro Tip: If you have an air fryer, reheat the frozen sandwich at 350°F (175°C) for 5-7 minutes to restore its crispy texture!
