Ina Garten’s 4-Ingredient Summer Appetizer You Can’t Miss!

My husband recently popped into the kitchen and posed his usual question, “What are you making?” At that moment, I was preparing Ina Garten’s Tomatoes Roasted with Pesto.

I explained the steps: The tomatoes are thoroughly seasoned and roasted for a short time before being coated with vibrant basil pesto and a hearty sprinkle of freshly grated Parmesan cheese. Afterward, these embellished tomatoes are baked until they bubble and the cheese turns a delicious golden brown.

He instantly responded, “How could that be anything but amazing?” And indeed, it isn’t just good—it’s fantastic!

Without overstating it, it’s clear this combination is fail-proof. Ina has a special talent for blending simple ingredients in a way that significantly enhances their appeal. Tomatoes and pesto naturally go well together, yet her technique of unifying these components upgrades the dish to a level worthy of the Barefoot Contessa.

What Captivates Me About Ina’s Roasted Tomatoes With Pesto

It’s hard to find a four-ingredient appetizer that packs as much flavor as this one. Like many of my favorite tomato dishes from Ina, the magic happens during roasting, which deepens the flavors and enhances the natural umami in the tomatoes.

Before the tomatoes go into the oven, they are liberally seasoned with high-quality olive oil, salt, pepper, and dried oregano. I adore the earthy and slightly sharp taste of dried oregano, though this recipe uses a whole two teaspoons. If that’s too much for you, consider adjusting to taste or substituting it with an Italian herb blend.

The first time I tried making this dish, I had plenty of basil available, so I decided to make my pesto from scratch. However, I’ve also successfully used store-bought pesto since then, so either option is viable.

While not traditional, I seldom use pine nuts in my homemade pesto due to their steep price. Ina’s recipe suggests a mix of walnuts and pine nuts, but I opted for pumpkin seeds instead. I find that any ingredient that introduces a nutty richness works well in this context.

Following Ina’s recipe typically results in more pesto than needed for the tomatoes, which is a plus. You can use the leftover pesto in sandwiches, scrambled eggs, or as a marinade for proteins. I like to freeze any extra pesto in ice cube trays, making it easy to add a burst of fresh, herby flavor whenever needed.

Lastly, the Parmesan cheese not only adds more depth to this already savory dish but also helps bind all the components together. While tasty, the combination of juicy tomatoes and oily pesto isn’t exactly tidy. The cheese acts as a perfect binder, making this appetizer both delicious and easy to serve.
