Braised Flat Beans in Tomato Sauce. This flat green beans recipe is delicious!

Have you ever cooked with flat green beans before? They are new to me!

Flat beans weren’t something I encountered very often. String beans, on the other hand, were abundant in summer and a staple at Thanksgiving dinner.

I saw some flat beans in the market here and grabbed some. I’m so glad I decided to give them a try.

I love oven-roasted green beans, but I’d never tried braising flat green beans until just recently.

Flat beans are perfect for braising. They hold their shape really well and become wonderfully tender. You will know they are finished when they have lost their “squeak.”

You can make this recipe with round green beans, but if you find some flat beans be sure to scoop them up!

Braised Flat Beans in Tomato Sauce! This is a great flat bean recipe!

I think I’ve made this flat beans recipe six or seven times in the last 3 months.  I just can’t get enough of it!

Tender beans coated in a luscious tomato sauce, studded with salty olives, served on top of a smear of whipped goat cheese — what’s not to love?

I originally thought to stir some chunks of feta right into the pan, but if I did that I’d be on my own eating a whole pan of beans.

I decided to use briny green olives to up the umami factor in this dish. It’s a wonderful addition!

You could use chunky feta instead, or cashew cheese if you eat a plant-based diet.

I happen to love sheep and goat cheese, so when I serve these braised flat beans I first spread some creamy goat cheese onto my plate.

The olive oil seeps out of the sauce and onto the cheese, just begging to be scooped up with a piece of baguette.

This dish is best served at room temperature. The beans benefit from a gentle resting period, and the flavors are at their best this way!

I usually prepare this early in the day, then let it hang out in the pan until it’s time for dinner. The leftovers are even better after a night in the fridge and an hour on the counter.

These braised flat beans are lovely as a side dish, but they also make a great addition to a tapas spread. Enjoy, my friends!

  • 3 tablespoons extra virgin olive oil - divided
  • 1 1/2 medium yellow onions - peeled and sliced vertically
  • 3 large cloves garlic - chopped
  • 1 14-ounce can crushed tomatoes
  • 1 pound flat beans - trimmed and cut into 1 1/2-inch pieces
  • 1 tablespoon aged balsamic vinegar
  • 2/3 cup halved green olives - about 10 olives, such as castelvetrano
  • Salt and pepper
  • 2 tablespoons feta cheese or goat cheese for serving - optional


  • Heat two tablespoons of olive oil in a large non-stick skillet (for which you have a lid) over medium-high heat. Once the oil is shimmering, add the onions and season generously with salt. Fry the onions until they are turning golden brown, about 4 to 6 minutes.
  • Turn the heat down to medium and add the garlic and canned tomatoes. Fill the empty tomato can halfway up with water and pour it into the pan.
  • Stir well, then add the flat beans to the pan. Cover and cook for 20 minutes, stirring occasionally.
  • Stir the balsamic vinegar into the sauce. Continue cooking, partially covered, for another 20 to 30 minutes or until the beans are very tender and have lost their squeak.
  • Fold the olives into the mixture along with the remaining tablespoon of oil. Sprinkle with salt and freshly ground black pepper.
  • Let the dish rest until it has cooled to room temperature. Serve with a crusty baguette and goat cheese, if desired.


Storage Info:
To store Braised Flat Beans, first, let the dish cool to room temperature. Once cooled, transfer it to an airtight container and refrigerate it. When stored properly, it will stay good in the refrigerator for up to 3-4 days. While you can freeze it, keep in mind that the texture of the beans may change slightly upon thawing, as they can become a bit softer. To freeze, place the cooled dish in a freezer-safe container or bag, removing as much air as possible. You can store it in the freezer for up to 2-3 months. To reheat, gently warm it on the stovetop or microwave, adding a bit of water if needed to maintain the desired consistency.

    Absolutely delicious. Thank you. 😊
    I made this dish with fresh from the garden beans (a generous neighbor with a fantastic green thumb). They were ready to enjoy after 25 minutes. No second simmer.

    I used Trader Joe’s Grilled chalkidiki green olives.

    Your recipe is a keeper!
