Tips

You can absolutely cook your own bacon if you prefer, but I like using fully cooked bacon to keep things quick and avoid the mess. It’s a simple shortcut that still delivers great flavor—without turning your kitchen into a cleanup project.

For the tomatoes, go with what looks freshest at the store—3 beefsteak tomatoes or about 5 medium vine-ripened tomatoes both work well. If the beefsteaks aren’t at their best, the smaller on-the-vine tomatoes are a great option and just as flavorful.

Kitchen Tools Required

Having the right kitchen tools makes this recipe even easier. A mini food processor quickly chops the bacon with almost no effort, and a mixing bowl with a rubber bottom keeps everything steady while you stir. Simple tools, less mess, and a whole lot less hassle.

How to Make Tomato Bacon Sandwich Triangles

Add the mayonnaise and mustard to a small bowl. I like using a 1.5-quart mixing bowl with a rubber bottom to keep it steady.

Place the bacon strips in a mini food processor and chop until finely minced, about 10 seconds.

Add the chopped bacon to the bowl with the mayonnaise and mustard, and stir until well combined.

If your tomatoes are especially juicy, place them between sheets of paper towel to absorb any excess moisture.

Lay out the bread slices and spread the mayonnaise mixture on one side of each slice. Arrange the tomatoes on half of the bread slices.

If you’re using beefsteak tomatoes, one slice per piece of bread works well. For smaller tomatoes, cut them to fit the bread.

Top with the remaining bread slices, spread side down, to form sandwiches. Using a serrated knife, cut each sandwich in half diagonally, then cut each half diagonally again to create four triangles.

Arrange on a serving platter and refrigerate until ready to serve. These can be made up to 2 hours in advance.

Optional: Cocktail & Drink Pairings for Tomato Bacon Sandwich Triangles

These Tomato Bacon Sandwich Triangles pair perfectly with something light, crisp, and refreshing. A classic gin and tonic or a Pomegranate Orange Spritz works beautifully to balance the richness of the bacon and the creamy spread. If you’re leaning into a casual happy hour vibe, even a chilled glass of rosé or a light beer keeps things easy and complements the flavors without overpowering them.

Whether you’re hosting a party or just putting together a casual snack spread, these Tomato Bacon Sandwich Triangles are the kind of appetizer guests always come back for—so don’t be surprised if they’re gone before anything else.
