I don't know if I trust someone who doesn't like a BLT. The BLT is a classic sandwich that continues to stand the test of time. But if you're asking me (which duh, you're reading this), sometimes it needs a little more flavor to keep things interesting. This BLT with avocado sandwich is a simple twist on tradition that adds creamy avocado slices to the mix.

A BLT is my favorite sandwich because you can literally eat this any time of day. Breakfast? Yes ma'am. Lunch? Duh. Dinner? Of course! Add some tater tots to complete the whole meal and you're good to go. Plus, if you've got leftover bacon, toss into a complimentary BLT pasta salad.

Tips, Tricks, and Reminders
- The best way to get the stem out of the iceberg lettuce is to slam the entire head stem-side down onto the counter. This will loosen then stem and will right out with a light tug.
- Feel free to throw in slices of chicken breast, turkey breast, a slice of cheese, or prosciutto if you want to amp up the meat and flavor.
- If you don't want to run the risk of the avocado slipping right out of the sandwich in just one bite, you can mash the avocado into the bread and then layer on the other ingredients. It helps big time.
The Main Ingredients

- Bread: To make a great BLT with avocado, the bread really does matter, but you could use whatever you have on hand. Just be sure to toast the bread enough so that it doesn't become soggy.
- Bacon: Traditional bacon is great, but you could always use turkey bacon or plant-based bacon instead. I love using an applewood smoked bacon on the thicker side.
- Lettuce: Iceberg lettuce is a classic, but don't shy away from experimenting with romaine, spring mix, baby arugula, or butter lettuce for a slightly softer bite.
- Tomatoes: Fresh summer tomatoes or juicy heirloom varieties add a sweet and tangy balance to your sandwich. Slice them thick for a hearty, satisfying bite.
- Avocados: Go for perfectly ripe avocados to achieve that creamy texture. Thin avocado slices fit beautifully into the sandwich without overpowering the other elements.
- Mayonnaise: The glue that holds it all together. Just enough mayo brings richness without creating a soggy sandwich.

Simple Swaps and Substitutions
- Swap out the sourdough bread for any type of bread you like such as rye, whole wheat, gluten free, ciabatta, or even in a wrap.
- Ditch the whole bread thing and make a BLT salad bowl.
- If you wanna get extra fancy, swap the mayo for an aioli or a thousand island dressing.
- Not into pork? You can use turkey bacon or a meat-alternative bacon.
How to make a BLAT

Step 1: Preheat your oven to 400°F and line a baking sheet with aluminum foil. Lay out your bacon slices evenly and bake until crispy. Thick-cut bacon works wonders here because it stays meaty while offering a satisfying crunch. Once it is fully cooked, lay the slices of bacon on paper towels to absorb any extra fat.

Step 2: While the bacon crisps up, slice your tomatoes thinly. If you can get your hands on heirloom or summer tomatoes, even better-they bring unbeatable sweetness and juiciness. Next, halve your avocado and cut it into even slices. Finally, grab your lettuce leaves and give them a quick rinse to maintain their crunch.

Step 3: Toast slices of bread to a golden brown, just enough to hold up to the juicy tomatoes and creamy avocado without falling apart.

Step 4: Now for the fun part-assembly! Start by spreading mayo on one side of each slice of bread. Layer on the lettuce for crunch, followed by tomato slices, crispy bacon, and creamy avocado slices. Top it with the remaining slice of bread, and press gently to hold it all together.
Mistakes I've Made (so YOU don't have to!)
- Do not toast the bread so much that it's hard to bite into. I find that a good BLT is made with bread that is toasted just enough that it gives a crunch, but also doesn't rip the top of your mouth when bitten into.
- Don't forget to add mayonnaise to both pieces of bread, and then layer with the lettuce first. This helps with the tomato and avocado slippage.
- Don't slice the tomatoes too thick, it won't fare our well for anyone, including your clothing.

BLT with Avocado FAQs
As I said earlier, truly any bread can work, I just always caution to use a crustier bread like a hearty sourdough, or a pullman loaf, white bread is great too, or even a seeded multigrain bread. The reason is because when you toast the bread you want it to be sturdy, and some breads get softer and soggier quicker than others.
Absolutely! Turkey bacon or plant-based bacon options work well if you're looking for a lighter or vegetarian-friendly twist.
Of course! Think cucumber slices, arugula (instead of iceberg), a slice of fresh roasted turkey or chicken, some Swiss or muenster cheese, or a drizzle of balsamic glaze.
You can add all of the chopped vegetables in a large ziplock bag and reuse the next day. For the bacon, you can place in a container and use up to 48 hours later. I would not toast the bread and then store it. If you want to make a BLAT sandwich another time, make the bread the day of.

Although BLT’s are a simple, classic sandwich, the added avocado just gives it the extra richness and creaminess I never knew it needed. Chef’s kiss!

I love ordering BLTs out at the diner, but never thought to make them at home. I also never baked my bacon before, so this recipe is officially my new favorite way to make bacon at home, and the BLTs were delicious!
