  1. Bring a large pot of lightly salted water to a boil; cook green beans at a boil until tender yet firm to the bite, 5 to 10 minutes; drain and transfer to a 9x13-inch dish.
  2. Cook and stir onions, vinegar, garlic, sugar, basil, and oregano in a skillet over medium heat until onions are softened and translucent, about 5 minutes. Reduce heat to medium-low, and continue cooking and stirring until onions are very tender and dark brown, 15 to 20 minutes more.
  3. Preheat oven to 400 degrees F (200 degrees C).
  4. Spread onion mixture over green beans and top with Parmesan cheese. Arrange tomatoes, cut sides down, atop Parmesan cheese layer.
  5. Bake in the preheated oven until cheese is melted and bubbling, about 35 minutes.

I love caramelized onions and green beans so I had great hopes for this dish. I knew the balsamic vinegar would add sweetness and had thoughts of omitting the sugar. Instead, I used just 1/4 tsp sugar and it was way too sweet for us. Salt and pepper was added to the onions with the garlic tossed in at the end of caramelizing so it would not burn and be bitter. A quick broil to melt the cheese and roast the tomatoes would save cook time.


I liked this alot! Very flavorful! I used a smaller pan for the green beans, since a 13x9 was too big to get an even layer of green beans on the bottom. Also, I used a little less onion than the recipe called for, and I used fresh grated parmesan cheese. Next time I will use more parmesan cheese to completely cover the greenish/brownish color of the onions and green beans, and maybe even mix some in with the green beans in addition to the top for extra flavor. I will definitely make this again!


Was looking for a recipe to use up some cherry tomatoes and I found this one. This is moving to the top of my side dishes list. It's excellent.
