Sourdough BLT Sandwich Recipe

Meet your new lunchtime obsession: the Sourdough BLT Sandwich.

Each bite is a perfect balance of salty, creamy, and fresh, with textures that just won’t quit. Whether you’re packing a killer weekend brunch or want to enliven an everyday meal, the Sourdough BLT Sandwich delivers flavor and satisfaction in every layer.

Ingredients You’ll Need

A killer Sourdough BLT Sandwich doesn’t need a long shopping list; it’s all about simple, high-quality ingredients coming together. Here’s what you’ll need—and why each one is absolutely essential to nailing the ultimate bite.

• Thick-cut bacon: Thicker slices offer a meatier, smoky bite and crisp up beautifully for that signature BLT crunch.
• Sourdough bread: Go for a sturdy, artisan loaf—its tangy flavor and hearty crust make the perfect base and soak up those bacon drippings.
• Ripe avocado: Mashed avocado adds creamy richness, acting as a buttery layer that balances the salt and acid.
• Mayonnaise: Smooth, tangy mayo ties everything together and keeps the sandwich juicy.
• Kosher salt and freshly-cracked black pepper: These basics amplify every ingredient, so don’t skip them!
• Tomato slices: Look for ripe, in-season tomatoes for a burst of juicy sweetness with every bite.
• Iceberg lettuce: Its crunch brings freshness and a satisfying snap—plus it holds up well to the heavier fillings.

How to Make Sourdough BLT Sandwich

Step 1: Cook the Bacon

Start with a cold skillet and lay your bacon flat, making sure the strips don’t overlap. Cooking them slowly over medium-low heat helps the fat render out, turning each strip into a crispy, smoky delight. Take your time—let the bacon get as crisp as you like, then drain on a paper towel to keep the sandwich from getting greasy.

Step 2: Toast the Sourdough

After you’ve cooked the bacon, pour off most of the fat but save a teaspoon in the pan for major flavor. Place the sourdough bread right into the skillet and toast only one side over low heat. This gives you a gloriously golden, slightly crisp exterior, while the other side stays soft and ready to soak up your spreads.

Step 3: Add the Spreads

Flip the bread so the toasted sides are down on your plate. Mash the ripe avocado onto the untoasted side of one slice—it should glide on like butter. Slather mayonnaise on the other slice, then season both with a touch of kosher salt and a few grinds of pepper to bring out all those beautiful flavors.

Step 4: Assemble the Sandwich

Next comes the build: arrange the crispy bacon on the mayo-slathered bread, followed by juicy tomato slices and a generous pile of iceberg lettuce. Top it all with the avocado-smothered slice, avocado side down, and press ever-so-gently to let the layers settle into each other.

Step 5: Serve and Enjoy

Seal the deal by slicing your Sourdough BLT Sandwich in half—diagonally, for that classic deli look—and dig in while it’s still warm and crisp. Every bite is loaded with a mix of rich, crunchy, and refreshing flavors that’ll have you planning your next one before you’re even finished.

How to Serve Sourdough BLT Sandwich

Garnishes

A Sourdough BLT Sandwich really shines with a few thoughtful garnishes. Try a sprinkle of flaky sea salt, a little extra cracked black pepper, or even a handful of fresh chives or microgreens on top. For a spicy twist, add a few thin slices of pickled jalapeño or a drizzle of hot sauce right before serving.

Side Dishes

It’s hard to compete with the Sourdough BLT Sandwich, but some classic sides truly round things out. Serve with crunchy kettle chips, a tangy pickle spear, or a small green salad tossed with lemon vinaigrette. In colder months, a cup of tomato soup on the side transforms this BLT into soul-warming comfort food.

Creative Ways to Present

Want to really wow your guests? Cut the sandwich into miniature sliders for brunch platters, or stack halves on a rustic wood board with an assortment of mustards and dipping sauces. For a picnic, wrap each Sourdough BLT Sandwich in parchment and twine—it’s practical, pretty, and Instagram-ready!

Make Ahead and Storage

Storing Leftovers

If you happen to have any leftover Sourdough BLT Sandwich (which is a rarity!), keep it tightly wrapped in foil or an airtight container in the fridge. Eat it within 24 hours for the best texture. The bacon will soften slightly and the bread may lose some crunch, but the flavors hang in beautifully.

Freezing

Freezing the fully assembled Sourdough BLT Sandwich isn’t ideal, as avocado and tomatoes don’t thaw well. However, you can cook and freeze the bacon ahead of time in a sealed bag—just crisp it up quickly in a skillet before assembling your fresh sandwich later.

Reheating

For a next-day treat, gently rewarm the bacon separately in a skillet or microwave, then quickly toast the sourdough again for a few seconds per side to revive its crispness. Freshen the veggies and spreads just before reassembling for the brightest, tastiest result.

FAQs

Can I use a different bread instead of sourdough?

Absolutely! While sourdough’s tangy flavor and sturdy texture are perfect for holding all the BLT fillings, you can swap in any hearty artisan bread or even a rustic whole wheat if you prefer.

How do I keep the sandwich from getting soggy?

To avoid sogginess, make sure to toast only one side of the bread (the side facing out), and assemble just before eating. Let any cooked bacon and tomatoes cool slightly before layering to prevent steam from softening the bread.

What can I use instead of mayonnaise?

If you’re not a mayo fan, try creamy Greek yogurt, a swipe of pesto, or even whipped goat cheese as an alternative. Each brings its own delicious spin to the Sourdough BLT Sandwich.

Can I make this vegetarian?

Definitely! Swap the bacon for crisped tempeh, smoky tofu, or a generous layer of roasted mushrooms. Combine with all the other fixings for a Sourdough BLT Sandwich that’s just as satisfying.

What’s the best way to mash the avocado?

Use a fork to mash your ripe avocado with a pinch of salt until it’s creamy but still a little chunky. This helps it spread easily without turning runny, keeping the texture perfect in your sandwich.
