We’re sharing all of our best tips for making your best BLT Sandwich. This is one of the most popular sandwiches in America. Watch the video tutorial and see why everyone is talking about this recipe.

What is a BLT?

BLT stands for Bacon, Lettuce and Tomato. Ok, ok, so we snuck in some avocado which makes it a BALT, but once you try this iconic sandwich with avocado, there is no going back. Everyone loves the flavor profile of an authentic BLT which is why we now have a BLT Salad and even a Breakfast BLT Sandwich.

Ingredients for BLT sandwich with bacon, bread, tomatoes, lettuce, avocados and sandwich spread

The Best Sandwich Sauce Spread:

We fell in love with this sandwich sauce when we tried the Chicken Bacon Avocado Sandwich at Kneaders restaurant. I asked for an extra side of sauce, took it home, and re-created it.

It’s just 3 ingredients and the combination is memorable: mayonnaise, sour cream, and a little bit of yellow mustard. Try it on your next BLT and you will have a new favorite.

How to Cook Bacon:

The easiest (and least messy) way to cook bacon is to bake it in the oven. We prefer regular thin-cut bacon for BLT’s because it’s easier to bite through, but thick-cut bacon will also work well if that is what you have on hand.

  • Regular Bacon: arrange in a single layer over a foil-lined rimmed baking sheet and bake in the center of the oven at 400˚F for 18-20 minutes.
  • Thick-Cut Bacon: Line a rimmed baking sheet with foil and place a wire rack over the foil. Arrange bacon over the rack and bake at 400˚F for 30-35 minutes. You can omit the rack but you will need to flip the bacon halfway through so the bottom gets crisp.

How to Assemble a BLT Sandwich:

  1. Start by cooking your bacon then preparing your sauce and toasting bread.
  2. Spread 1 Tbsp sauce over the bottom bun then layer with lettuce, tomatoes, bacon, avocado, and a sprinkle of salt and pepper.
  3. Spread another 1 Tbsp sauce over the top bun and place it over the avocado.

Can I Make a BLT Ahead?

A BLT sandwich is delicious for a work or school lunch. To keep the avocados vibrant, toss the avocado slices in a little lemon juice before adding to the sandwich.

To keep the bread from getting soggy, package the tomatoes and sauce separately and add them just before serving.

More Sandwich Recipes You’ll Love:

Admittedly I’ve never been a sandwich person, but the BLT has my name all over it. It has to be truly special for me to love a sandwich and these never fail to impress. It’s so hard to pick just one favorite but you must try the sliders!

    Best BLT ever. Thank You so much for this recipe. A half was enough for my husband and I. Followed the recipe to the letter. Next time I may mash the avocado but other than that best BLT ever!

    Hi! What specific kind of bread did you use?

      It was a thick-sliced artisan bread (pre-sliced and purchased at Fred Meyer in the regular bread aisle).

    Always our favorite. BLTA and a sprinkle of lemon pepper on the tomatoes. Yum, yum. Like the added toasting in the pan.

    Greetings from the UK -Fabulous recipe can I sub the sour cream with buttermilk? Can’t get hold of it right now. Or do you have any other suggestions. Also, if I was making this vegan any ideas for a sub for sour cream. I would use vegan mayo and shitake mushroom bacon…. thanks

      Hello Nina, I haven’t personally tried using buttermilk as a substitute I imagine vegan mayo should work well but I don’t know of any substitute for sour cream that I can recommend.

        How about using %fat free yogurt instead of the sour cream? W W does it all the time and I think it works well.

    The sauce, sour cream, mayo and mustard is great on potato salad or mac salad, just Dijon rather than yellow mustard.

    We had your BLT for lunch, it was delicious as you had promised. The sauce is what I put on my Potato Salad, SO good as a sandwich spread…Thank you for that clever idea. Unfortunately, my Avocado was green (seems like they are always too ripe, or not ripe enough.) You and your little boy are the cutest! I love your videos. It was easy to get my 3 grown Gen Z grandsons to watch your videos and try some of your recipes.

    A little trick to save your clothes. When you take a bite, often the tomato skins or the edge of the bacon will not bite away free and drag ingredients out to run down your chin and clothes. I notch the edges of the tomato skins with a knife which gives you a cleaner bite. Same with the bacon BEFORE cooking and also smaller pieces of lettuce. Hopefully you will get to wear you clothes the rest of the day with this little trick. Great recipe Natasha. Thank you.

    My guess how you did that trick is that you made a hole in the bag and someone was holding the bag and gave you the food through the hole in the bag

    The sauce sounds awesome, I will give it a try next time. We just had BLATS (sounds funny right) down the beach. Made a big sub on garlic bread (loaf, reheated) because it was a mustgo. OMGoodness!
    One hint for oven cooked bacon – cover it with a sheet of parchment and there’s no splatters to clean up.
