A Bharta is a roasted vegetable mash traditionally made with eggplant (baingan bharta). We thought of using butternut squash in the fall and winter seasons because that vegetable is so popular and prevalent in the States. This makes a terrific Thanksgiving side dish— in fact, we introduced this dish on the Thanksgiving menu at Rasika. The tenderness of butternut squash can vary, so start checking your roasting time at the 20-minute mark. That may be enough time for the cubes to soften. Or it may take up to 30 minutes. The same holds true for the cooking time in Step 4, when you want the finished squash to be dry rather than loose. Some squash have more moisture in them than others, so this step could perhaps take an extra minute or two.
