Some sandwiches are complicated, and some sandwiches are perfect. The BLT belongs firmly in the second group. Bacon, lettuce, and tomato — three ingredients, plus bread and a swipe of mayonnaise — and yet when each one is treated properly, the result is greater than anything with twice the ingredient list. It is salty and sweet, crisp and juicy, rich and fresh all at once, and it has been earning its place on lunch tables for the better part of a century for very good reason.
The thing about a BLT is that there is nowhere to hide. With only a handful of ingredients, every single one has to be good. Flabby bacon, pale winter tomatoes, or limp lettuce will sink the whole sandwich, no matter how nice your bread is. But get it right — bacon cooked until it shatters, a tomato so ripe it barely holds its shape, lettuce with real crunch, bread toasted golden — and you have something that needs no improvement at all. That is the whole philosophy of this recipe: do the simple things properly, and let the ingredients do the talking.
I make BLTs most often in the summer, when tomatoes are at their peak and the whole sandwich tastes like the season. But honestly, a good BLT works year-round if you choose your tomatoes carefully. Look for the ripest ones you can find, even if that means a smaller tomato from a good grocer rather than a big, hard one from the bargain bin. The tomato is not a garnish here — it is a full partner in the sandwich, and it deserves the same respect as the bacon.
Why You’ll Love This Recipe
First, it is fast. Twenty minutes from start to finish, and half of that is the bacon cooking itself in the oven while you do something else. There is no marinating, no sauce to build, no special technique to learn. If you can toast bread and fry bacon, you can make a great BLT.
Second, it is honest food. No mystery ingredients, no trends, no fuss. Just a sandwich that tastes exactly like what it is, and what it is happens to be wonderful. In a world of over-complicated lunch ideas, there is something deeply satisfying about a classic done well.
Third, it is endlessly adjustable without ever stopping being a BLT. Add a fried egg and it is breakfast. Add avocado and it is California-style. Add a smear of pimento cheese and it is a Southern diner classic. The base recipe here is the pure version, and from there you can wander as far as you like.
And finally, it is a crowd-pleaser. Kids love it, adults love it, picky eaters love it. If you need to feed a group at lunch with no dietary drama and no complaints, a platter of BLTs with a bowl of chips is about as safe a bet as cooking gets.
Ingredients
- 8 slices thick-cut bacon
- 4 slices good sandwich bread (white, sourdough, or country-style)
- 2 tablespoons mayonnaise, preferably full-fat
- 4 large leaves of iceberg or romaine lettuce
- 1 large ripe tomato, sliced into 4 thick slices
- Salt and freshly ground black pepper
- Optional: 1 ripe avocado, sliced
Method
- Cook the bacon in the oven. Preheat the oven to 400°F. Line a rimmed baking sheet with foil or parchment paper, lay the bacon slices in a single layer without overlapping, and bake for 15 to 18 minutes, until deeply golden and crisp at the edges. Oven bacon cooks more evenly than stovetop bacon, it does not curl up, and it frees you from standing over a splattering pan. Drain the bacon on paper towels.
- While the bacon cooks, prepare the tomato. Slice the tomato into 4 slices, each about 1/4 inch thick. Lay the slices on a plate, season them generously with salt and a few grinds of black pepper, and let them sit for at least 5 minutes. Salting draws out a little moisture and concentrates the flavor — this small step is the difference between a watery sandwich and a juicy one.
- Toast the bread. When the bacon is nearly done, toast the bread slices until golden brown on both sides. You want real toast, not warm bread — the crispness of the toast is structural, not decorative. It keeps the sandwich from collapsing under the tomato and gives every bite a satisfying crunch. If you like, you can butter the bread lightly before toasting for extra richness.
- Spread the mayonnaise. Spread a generous layer of mayonnaise on one side of each slice of toast. Be generous here — mayonnaise is the moisture barrier that protects the bread from the tomato, and it adds a creamy richness that ties the whole sandwich together. Light mayonnaise does not do this job as well, so use the full-fat kind.
- Build the sandwich. Lay a lettuce leaf on two slices of toast, mayonnaise-side up. The lettuce goes against the bread on both sides in a proper BLT, because it acts as a second barrier against tomato juice. Place two tomato slices on top of the lettuce, then stack four slices of bacon on each sandwich. If you are using avocado, layer the slices over the bacon.
- Close and press gently. Top with the remaining toast, mayonnaise-side down. Press the sandwich down gently with the palm of your hand — just enough to settle the layers together, not so hard that the tomato slides out. A gentle press makes the sandwich easier to pick up and eat without it falling apart.
- Slice and serve. Cut each sandwich in half, either straight across or on the diagonal. A diagonal cut looks better and gives you a wider face of filling to admire. Serve immediately, while the bacon is still warm and the toast is still crisp, with chips, pickles, or a simple side salad.
Tips and Variations
Bacon quality matters more than anything else in this recipe. Thick-cut bacon gives you a meatier bite and a better chew than thin bacon, which can disappear into the sandwich. Look for bacon with a good balance of meat and fat — all fat renders away and leaves you with nothing, all meat stays tough. A good butcher or a quality grocery brand makes a real difference.
Tomato choice is the second-biggest factor. In summer, use whatever ripe, fragrant tomato you can find — beefsteak, heirloom, even a big Roma. Out of season, cherry tomatoes halved and lightly salted can actually beat a pale, mealy slicing tomato. Never refrigerate a good tomato, by the way — cold kills both flavor and texture. Keep tomatoes on the counter, always.
Bread is a matter of taste, but it should be sturdy. Soft, thin sandwich bread turns to mush under a juicy tomato. Sourdough adds a lovely tang, country white adds a wholesome chew, and a good Texas toast makes the whole sandwich feel like a diner treat. Whatever you choose, toast it well.
If you want to dress it up, the classic additions are avocado, a fried egg, or a slice of sharp cheddar melted onto the toast. A smear of chipotle mayonnaise instead of plain adds a smoky heat that pairs beautifully with bacon. And if you are feeling Southern, a thick spread of pimento cheese turns a BLT into something truly special.
For a lighter version, use center-cut bacon, which is leaner, and go easy on the mayonnaise — or swap half of it for mashed avocado, which gives you creaminess with better fats. The sandwich stays satisfying, just a little less indulgent.
Frequently Asked Questions
Why cook the bacon in the oven instead of a pan?
Even cooking, less mess, and no curling. Stovetop bacon cooks unevenly, splatters everywhere, and curls up at the edges, which makes it hard to layer neatly in a sandwich. Oven bacon lies flat, renders evenly, and you can cook a whole batch at once. Once you try it, you will rarely go back to the pan for sandwich bacon.
Can I make BLTs ahead of time?
Not really — a BLT is a sandwich that wants to be eaten fresh. The toast goes soft, the lettuce wilts, and the whole thing loses its magic within an hour. What you can do ahead is cook the bacon: it keeps in the fridge for up to four days and reheats in a hot skillet in about a minute. Then assembly takes two minutes when you are ready to eat.
What is the best lettuce for a BLT?
Iceberg is the classic choice, and for good reason: it is cold, crisp, and shatteringly crunchy, which is exactly what this sandwich needs. Romaine is a close second and adds a slightly greener flavor. Butter lettuce is too soft and will disappear. Whichever you use, make sure it is dry — wet lettuce makes a soggy sandwich.
My BLT always falls apart. What am I doing wrong?
Usually one of three things: the bread is not toasted enough, the tomato slices are too thick and slippery, or the sandwich is overloaded. Toast firmly, slice the tomato no thicker than 1/4 inch, salt it and let it drain briefly, and layer the lettuce against the bread on both sides. A gentle press before slicing helps too.
Is a BLT really just three ingredients?
At its heart, yes — bacon, lettuce, and tomato, plus bread and mayonnaise. That is the whole point. The BLT is proof that a short ingredient list, executed well, beats a long one executed carelessly. Every addition after that is a variation, not an improvement on the original.
There it is: the BLT, done properly. No tricks, no shortcuts that cost flavor, just crisp bacon, ripe tomato, crunchy lettuce, golden toast, and good mayonnaise. It takes twenty minutes, it uses ingredients you probably already have, and it reminds you why some recipes never go out of style. Make one this week, and make it properly — your lunch break will thank you.
