Tomato Confit BLT Sandwich

Today’s sandwich is the “Tomato Confit BLT.” It combines crisp bacon, Boston bibb lettuce, tomato confit, and mayonnaise on fresh-baked bread.

Notes: Is there a better sandwich on planet Earth than the classic bacon, lettuce, and tomato sandwich? Variations on the sandwich’s classic structure are almost always completely unnecessary, and often take away from what is already a perfectly balanced combination of crisp, salty, fatty bacon, with crunchy, cool lettuce, and a juicy, acidic sweetness from the tomatoes. Adding cheese or avocado or lobster is almost never an improvement, such is the excellence already inherent in this sandwich.

Unleeeeeessssssss…you are in Maine in the middle of Winter when your BLT craving hits. There’s a reason we tend to think of BLTs as a Summertime sandwich; the deliciousness of tomatoes picked at the height of their season are a major contributor to your overall impression of a BLT. And unless you are willing to take out a sketchy payday loan on a bunch of organic hydroponic vine-ripened vat-grown stem cell tomatoes flown in from Argentina, you’re simply not going to scratch your BLT itch with the kind of tough, flavorless, pale tomatoes found at the supermarket this time of year.

Enter the “Tomato Confit BLT,” one of the few variations on the classic sandwich that I dare say may be better than the original. Normally, when I think of “confit,” I think of something French, poached in its own fat, as with duck, until the flesh becomes impossibly tender and soft. Adding fat to meat imparts a huge blast of flavor, and even acts as a preservative. It’s a wonderful way to coax additional flavor and texture out of an ingredient that may need a boost, like the tough leg of an aquatic waterfowl, say, or the three-for-a-dollar softball-sized tomatoes at Hannaford.

“Oh ho,” you say, “but tomatoes are a fat-free food! How in the world are we to prepare them confit-style?” That’s easy. We’re going to cover them in bacon fat. A little bacon fat, a sprinkle of salt, and three hours in the oven at low temperature are all you need to transform tough, flavorless tomatoes into bite-sized grenades of acid and flavor with the consistency of a warm custard. Piled high on a BLT, they bring more tomato flavor to the sandwich than you ever thought possible.

The rest of the standard BLT rules apply. Use a fresh loaf of sourdough, or a loaf of Jillian’s no-knead Dutch oven bread. Get the thickest-cut bacon you can find (I used Oscar Meyer “Super Thick Cut”), and cook it slow and low in a frying pan until it is dark brown and crisp, but still chewy. You don’t want bacon that shatters when you take a bite. I like a soft Boston-style lettuce, and as much Hellmann’s Blue Ribbon as I can fit onto a butter knife, on both sides of the bread, please. Toast your bread in a little butter on just one side, so that the outside of the bread gets a little crunchy, while the inside stays soft and warm. Spend a little time making a tomato confit, and your reward will be one of the best BLTs you’ve ever tasted.

Place a paper towel over the mouth of a heat-proof container, and carefully pour bacon fat through paper towel to remove any chunks or burned bits.

Slice tomatoes to 1/3 inch thick, and arrange on parchment paper in a single layer on a large baking sheet, or two if needed.

Using a teaspoon, drizzle each tomato with some of the strained bacon fat. Turn each tomato over, and repeat so that both sides are covered in fat. Sprinkle each tomato lightly with Kosher salt.

Bake in preheated oven for about three hours, flipping once. Check tomatoes often during the last half hour, and remove before any blackening occurs.

Butter one side of each slice of bread, and grill butter-side down in a frying pan over medium heat, until one side of bread turns crisp and golden. Remove from pan.

To assemble: For each sandwich, spread mayonnaise on two slices of bread, with the toasted side down. Arrange a layer of bacon, then the lettuce, then half of the tomatoes on one slice of bread. Top with remaining slice and serve.

  1. I must say that I am surprised that you feel that the only fresh tomatoes available to Mainers are the: “…organic hydroponic vine-ripened vat-grown stem cell tomatoes flown in from Argentina…”. You must have missed the fact that Backyard Farms is in Madison, Maine and grows them year round and has been for some years now. (Check a Maine store near you!)

    PS: Your tomato confit would be nice in place of roasted tomatoes in a red sauce, and I am sure makes this sandwich better! Lyn

  2. My mother taught me to save all my bacon grease. Great on any kind of green beans (especially haricots verts) also try browning some bread crumbs in bacon grease for a topping for veggies, chowder, tomato soup.

  3. Question? Can these be made in bulk and saved? Looks like they are being dried but I know dried things with fat can go rancid. So could these be made ahead and frozen? I think its a great idea and Id like to have them around for when I need them.

    1. That’s a great question, and one I don’t really know the answer to. I believe I have read that they can be jarred and stored in oil, but I don’t have any more details than that. If freezing them works out, would you please circle back and let us know? Thanks!

  4. My tomatoes are in the oven as we speak. I’m experimenting with some grape tomatoes that are pretty flavorless and will see about freezing them myself. Can’t wait.

    1. Awesome! My guess about the grape tomatoes is that they will shrivel away to nothing…but please let me know how they turn out!

  5. i’m sorry but these don’t look like confit tomatoes to me. they look like semi dried in the oven tomatoes?
