Step-by-Step Instructions
- Slice the Tomatoes:
- Cut the tomatoes into thick even slices about one half inch each Take your time to make sure the slices are sturdy and will hold up to marinating
- Layer the Tomatoes:
- Arrange the tomato slices in a single layer in a large shallow dish This helps every piece soak up the marinade rather than just the ones on top
- Make the Marinade:
- Combine olive oil red wine vinegar finely chopped red onion minced garlic parsley basil salt and black pepper in a jar with a tight lid Shake hard until the mixture is emulsified and everything is blended together
- Pour and Marinate:
- Pour the marinade evenly over the tomato slices Make sure every slice is coated Cover the dish tightly and let it sit for at least two hours on the counter or up to a full day in the refrigerator for extra depth
- Serve and Garnish:
- Bring chilled tomatoes back to room temperature before serving Transfer carefully to plates drizzle with the marinating juices and sprinkle with more chopped herbs for a fresh look and flavor

I never skip the basil in this recipe because its fragrance reminds me of picking herbs in my backyard during late summer Every time I make this my kids jump in to help whisk the marinade and sneak tomato slices
Storage Tips
Keep marinated tomatoes in an airtight container in the fridge for up to two days The flavors deepen over time but the texture of tomatoes is best within the first twentyfour hours If they sit longer just give them a quick toss before serving
Ingredient Substitutions
- If you do not have red wine vinegar balsamic or sherry vinegar can work in a pinch
- No fresh herbs Try the dried versions but use one third the amount for similar intensity

Serving Suggestions
