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.

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.

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!

    My family loves your recipes! We got creative this time, and fried green tomatoes using your zucchini breading and added them to these sandwiches. So good! Thank you 😋

    Hi, this recipe looks lovely, but I have a question about the sauce. Is there a substitute for the sour cream that you think would work?

      Hi Emily, I don’t know of any substitute for sour cream that I can recommend as I have not tried any substitution for it yet.

      Hi Emily, plain Greek yogurt would work well in place of sour cream.

    Best BLT I’ve ever made or ordered anywhere! I didn’t have avocado but otherwise made this exactly as written. I used Sarah Lee Artesano bread and thick cut bacon. I was surprised that such a simple sauce elevated the sandwich so much. My husband generally avoids mayo, but he was like your son and used extra as dip! Mmmm!

    Actually the simple Sause idea was a great addition, I kicked it up a bit by adding a Tbsp of ground horseradish.

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

          My favorite is Dave’s killer bread. The yellow Seed is the best, at least for me. Even good old fashioned white wonder bread, however they seem to have changed the recipe for the bread. It does not seem as soft and fluffy as before.

    The simplicity of this sauce and addition of adding avocado to the sandwich takes it to a new level of yum! Natasha, you are amazing!
