A BLT is only as good as its ingredients, and in August at HeathGlen Organic Farm, the ingredients are exceptional.
Heirloom tomatoes straight from the field, basil from the herb garden, thick-cut bacon, and sourdough from the local bakery.
The one small tweak that takes this sandwich over the top is fresh basil pureed into the mayonnaise. It’s a simple addition that ties everything together.
What Makes the Best BLT?
If you’re going to keep the BLT simple and classic, you want to use the best ingredients possible. Here’s what to look for:
- The bread: Sourdough, toasted golden brown. The tang complements the tomatoes.
- The bacon: Thick-cut, fried crisp. About 3-5 minutes over medium-high heat.
- The tomatoes: Heirloom if possible, sliced thick and sprinkled lightly with kosher salt to bring out flavor.
- The lettuce: Crisp frilly butterleaf. It adds texture without overwhelming.
- The mayonnaise: Real mayonnaise pureed with fresh basil leaves. Process ½ cup mayo with ½ cup packed basil in a food processor until smooth.
- Assembly: Spread basil mayo on toasted bread. Layer bacon, then tomatoes, then lettuce. Top with second slice of toast.

What About a Winter BLT?
Finding a tomato with flavor in winter is rare, and grocery store tomatoes usually disappoint. But you can still enjoy a BLT in winter.
Try a homemade tomato jam (or purchase one online) instead of fresh tomatoes. The concentrated flavor satisfies the craving when heirloom tomatoes aren’t in season.
