Personally, I like to let the tomatoes shine in this recipe, but you could also add some crumbled bacon or pancetta for a crispy salty crunch.

If you are not a fan of frittatas, then I’d venture to guess that you’ve never had a good one. A good frittata is light and delicious with a soft, creamy mouthfeel that is ultra satisfying.

The trick to fabulous frittatas

When it comes to making frittatas (and quiches too), the key is in the egg to dairy ratio. You just can’t get a smooth creamy frittata without it, and skim milk is not going to cut it.

Whole milk or cream blended with eggs makes for a smooth, silky texture and extremely satisfying dish.

You also must not overbake a frittata. You want it to be a little bit jiggly in the center when you pull it out of the oven. It will continue to cook in the hot dish or pan, so if you wait too long to pull it out, you can easily overcook it.

This is especially true if you’re cooking your frittata in a cast iron pan.

Choose heirloom tomatoes for this frittata dish

The quality of the tomatoes you choose in this recipe will make a big difference. A lot of tomatoes at the grocery store are watery and bland. That’s not going to be any good in any recipe.

Of course, I think you should grow your own, but the farmer’s market is a great alternative for anyone who can’t grow tomatoes. Choose some red, purple, and green tomatoes in various shapes and sizes.

Since we’ll be adding sliced tomatoes to our egg mixture. It’s important to remove as much of the tomato juices as you can before putting them in your dish.

The juices will water down your egg mixture sacrificing the smooth creamy texture, so we’ll slice our tomatoes and lay them out in a single layer on some paper towels and let them drain for a few minutes.

I love the flavor combo of tomatoes with mozzarella and basil, but you could change up the herbs or cheese to your liking if you wish.
