Make the filling: Heat oil in a large high-sided skillet over medium heat. Cook onions, stirring occasionally, until caramelized, about 25 minutes. Add garlic, and cook until fragrant, about 3 minutes. Let cool.
Toss onion mixture, tomatoes, flour, and red-pepper flakes with 1 1/2 teaspoons salt and some pepper.
Preheat oven to 375 degrees. Make the biscuit topping: Whisk together flour, baking powder, and 1 teaspoon salt in a bowl. Cut in butter with a pastry cutter or rub in with your fingers until small clumps form. Stir in cheese, then add cream, stirring with a fork to combine until dough forms. (Dough will be slightly sticky.)
Transfer tomato mixture to
a 2-quart baking dish (2 inches deep). Spoon 7 clumps of biscuit dough (about 1/2 cup each) over top in a circle, leaving center open. Brush dough with cream, and sprinkle with remaining tablespoon cheese. Bake until tomatoes are bubbling in the center and biscuits are golden brown, about 1 hour 10 minutes. Transfer to a wire rack. Let cool for 20 minutes.
I made this last summer and although we liked it, the whole tomatoes were exploding hot juice as we tried to eat it! I made it again today and poked each tomato with the tip of a sharp knife. That helped a lot, but as others have commented the biscuit topping was done by about 45 minutes. Next time I would cook the filling 15 minutes or so, stir and then add the biscuits. I also used sharp cheddar cheese. Yummy! Doubling the onions wouldn't hurt, either.
Love making this recipe. Made it last year a few times and couldn't wait for my cherry tomatoes to ripen this year so I could make it again. I just wondered if anyone knows how many calories are in this lucious cobbler. Thanks.
I bought gruyere from Trader Joe's but when I grated it I found it somewhat bland, so I did half gruyere and half pecorino romano. The top was very brown after 45 minutes so I pulled it out. I would half each of the tomatoes next time so that the filling would be more blended. I'd probably double the onions, too. Overall, though, this is a brilliant idea and was a delicious dinner.
Really delicious with in season tomatoes - there was some leftover which reheated well and was still as flavorful the next day. A great dish to bring to a summer dinner- would be good even at room temp.
This recipe was delicious! I was short on cherry tomatoes & had to substitute slicing tomatoes which made it a little watery so I would not recommend that, but the flavor was great.
I made this last night, but could not find a shallow 2 qt. dish to cook it in. I used a deep 2 qt dish, and the biscuit topping was done after 44 min. cooking time. Not all of the tomatoes were as done as I would have liked them to be, but the flavor of the dish was fabulous. I did not substitute anything, and was so glad that I bought the gruyere. Do not use anything other cheese or you will miss some of best tasting biscuit topping that goes so well with the tomatoes.
