Making delicious marinated tomatoes is simple; just use the right technique and ingredients. Let the tomatoes soak up a light champagne vinaigrette, then top them with shallots and capers. Champagne vinegar has a softer flavor than most vinegars, which lets the summery tomato flavor shine through.

A Cathedral-Inspired Marinated Tomato Recipe

My husband and I go to New York to see musicals whenever we can. One of our favorite NYC restaurants is Cathedral. Their tomato provençal is my absolute favorite recipe. Their recipe uses tomatoes that are marinated and served raw (the opposite of a true tomato provençal, which initially threw me for a loop), a perfectly seasoned, marinated heirloom tomato salad.

While developing this recipe, I focused on addressing a common complaint about marinated tomato salads: watery tomatoes. Salting and lightly curing the tomato slices helps solve this complaint.

What Makes This Marinated Tomato Recipe Unique

  • Salting tomatoes and lightly curing them for 20 minutes helps to remove excess water. That, in turn, keeps your marinated tomato slices from becoming waterlogged.
  • The champagne vinaigrette is gentle, creating a subtle yet balanced flavor.
  • I use heirloom tomatoes, but you can use any kind or size.
  • This is a perfect summer tomato recipe when heirlooms are at their peak!

Ingredients

Ingredients used in making marinated tomatoes (tomatoes, shallot, olive oil, champagne vinegar, capers, Dijon mustard, thyme, parsley, and basil

Key Ingredient Notes

Heirloom or beefsteak tomatoes

Look for ripe, heavy, and firm tomatoes. You want to avoid under-ripe ones. They need more time to develop flavor.

Champagne vinegar

Champagne vinegar is my first choice for making marinated tomatoes. The flavor is lighter than red wine or balsamic vinegar. If you do not have champagne vinegar, you can use white wine vinegar. It’s close.

Dijon mustard

Add a small amount of Dijon to emulsify the vinaigrette. If you skip this ingredient, your vinaigrette will most likely separate.

How to Marinate Tomatoes

Step One: Prepare the tomatoes

Slice the tomatoes about half an inch thick, skin on. I recommend using a mandoline for even slices. Lay them flat on a rack or on paper towels. Generously salt them with flaky sea salt and let them sit for 20 minutes. After 20 minutes, blot the tomatoes dry.

Step Two: Prepare the dressing

Whisk together the olive oil, champagne vinegar, Dijon mustard, maple syrup, dried thyme, salt, and pepper. Taste before using and adjust to your preference.

Step Three: Arrange

Arrange the tomatoes on a platter. Scatter the shallots and capers over the top. Pour the vinaigrette over them and let them marinate at room temperature for 15-30 minutes. If you marinate them longer, the tomatoes risk losing their structure and releasing water.

Step Four: Serve

Just before serving the sliced, marinated tomatoes, add the basil, parsley, a fresh drizzle of olive oil, a light squeeze of lemon, flaky salt, and freshly cracked pepper. Add the herbs last to keep their texture and color.

Variations and Substitutions 

Cheese

A little crumbled feta or vegan feta can add a lot of flavor. But only a slight amount. Too much changes the personality of these marinated tomatoes. 

Herbs

I wrote this recipe with basil and parsley. You can swap in mint for the basil, parsley, or both.

How to Store Marinated Tomatoes

This recipe is best when eaten within 30 minutes of marinating. I do not recommend storing or making these seasoned tomatoes ahead of time.
