Romano beans need a long cooking time; otherwise they will be tough. This long slow cooking gives them a deep sweetness and silky texture and when they are paired with tomatoes and herbs you get a dish that is tender and full of robust Italian flavor.
I grow Romano beans at HeathGlen Organic Farm out of frustration. They’re hard to find in grocery stores and only occasionally appear at farmers’ markets in late summer. If you have garden space, they’re worth growing yourself.
This recipe pairs the beans with smashed cherry tomatoes, which happen to peak at the same time. The technique came from Lynn Rossetto Kasper, the Italian cookbook author who buys tomatoes from my booth at the St. Paul Farmers’ Market.
She told me cherry tomatoes are excellent just mashed up and quickly made into a sauce. She was right.

What are Italian Romano beans?
Romano beans are wide flat beans that are also referred to as Italian flat beans. They are NOT Italian broad beans….those are called fava beans.
Romano beans are meaty, with a crispy crunch to them. I much prefer them over green string beans. Alas, they are not that easy to find.
Sometimes you will find them at farmers’ markets in the late summer, but they are not a common sight in the local grocery stores. I ended up growing them myself out of frustration over lack of availability.
If you can find them (or grow them) however they are well worth the trouble. They can take a boring bean dish over the top and become a main dish all alone if you are a vegetarian.
If you have any room in your garden, try growing Italian flat beans at home!
Romano beans (or flat beans) are often braised with other vegetables. In the recipe below I have slow-cooked them with smashed cherry tomatoes which are at their peak at the same time as the beans.
I’ve added a bit of fruit vinegar to the pan to brighten up the meaty beans.
Flat beans fit into a slow-carb or keto diet, where vegetables are important to ensure you get the right micronutrients.

Dragon’s Tongue Heirloom Beans
A specialty type of flat bean is a Dutch heirloom bean called “Dragon’s Tongue”. Similar in taste to the Romano but a beautiful purple-speckled color.
Just know that the beautiful color disappears when cooked and they turn pale yellow. If you want to preserve the color, blanch them quickly and use them in salads.
Here is what they look like fresh:

Pairing Flat Beans with Cherry Tomatoes:
I have the good fortune to live in the same area as Lynn Rosetta Casper, the well-known Italian cookbook author and radio personality.
She honors me every year by purchasing tomatoes from my farm booth at the St. Paul Farmers Market and chatting with me about how she uses them.
I’m always amazed at the varieties she selects and one day when the big slicers were gone she picked up a bunch of cherry tomatoes. She told me they’re actually quite good just mashed up and quickly made into a sauce.
Inspired by Lynn’s smashed cherry tomatoes, I mixed them with Italian flat beans and cooked them down to a tender, sauced vegetable side dish.
Cooking Romano Beans with Vinegar
Many chefs will tell you that the secret ingredient to take a dish over the top is a splash of acid. This can take the form of lemon juice, lime juice or any number of vinegars.
I tested this flat bean recipe first with a “tomato vinegar” to enhance the cherry tomatoes already in the dish. The second test was with cranberry vinegar which gave it a whole new flavor.
Fruit vinegars may be difficult to find so you can just use the type of vinegar you have on hand. I do have a detailed process including ratios of fruit to vinegar however, If you want to make your own homemade fruit vinegar
Using lemon juice for the acid tends to add a brighter taste, whereas the vinegars add a more subtle acidity. I often opt for vinegar as I think it allows the flavor of the ingredients to shine more.
Lemon juice can sometimes be overpowering to me.
Fruit vinegars pair nicely with all kinds of vegetables and proteins. This sheet pan of roasted veggies sprinkled with fruit vinegars is a recipe we make frequently in the Summer and Fall.

FAQ
Regular green beans work but have less meaty texture. Haricots verts (French green beans) are too delicate for this long cooking method. If using regular green beans, reduce the cooking time.
Yes. Use about 14 ounces of canned diced tomatoes, drained. Fresh cherry tomatoes have brighter flavor, but canned work in a pinch.
Any vinegar works. Fruit vinegars (tomato, cranberry, raspberry) add complexity. Red wine vinegar or sherry vinegar are good standard options. Even apple cider vinegar works.
Refrigerated, up to 3 days. Reheat in a saucepan. The dish is also good served at room temperature.
Cod, pork chops, roasted chicken, or grilled sausages. The tomato-bean combination is Italian in character, so it pairs well with Mediterranean proteins.

I was skeptical about the vinegar but it MAKES the dish. I halved the recipe because we just had a handful of beans. I used apple cider vinegar, two ripe red better boy tomatoes from the garden and everything else exactly as the recipe describes. The flavor was unbelievably good. We picked up two pounds of Roma beans at the farmers market and I’ll make a big pot this time. Enough to share!
So glad you liked it Chris. I am having such a hard time finding Romano beans this year. I usually grow them, but some varmit ate them all down and I can’t find any at the farmers market. Are you in Minnesota? If so, which farmers market did you find them at?
