- 1
Bake. Heat oven to 400°. Butter one shallow 2-qt. Baking dish. Melt Butter in a (2 Tbsp) mid-sized skillet over a medium-high flame. Add breadcrumbs; cook, mixing often, till a deep gold, 5–7 minutes. Move to a little bowl and toss with ½ cup Parmesan and Thyme leaves (1 Tbsp); add salt and pepper till it tastes right and keep to one side. Bring cream, broth, thyme sprigs, and leftover 2 Tbsp. Butter to a simmer in a mid-sized saucepan over a mid-sized flame; add salt and pepper till it tastes right. Remove from heat, cover, and leave to sit 10 minutes; discard thyme. Cover; hold warm. Toss vegetables in a big bowl; add salt and pepper till it tastes right. Set out ⅓ of vegetables in dish plus top using ½ cup Parmesan. Repeat layers; top using leftover vegetables. Pour cream mixture over; put a piece of baking paper directly on top of gratin. Bake till vegetables are crunchy-tender plus cream is thickened, 50–60 minutes. Uncover, top using breadcrumb mixture, plus cook till gratin is bubbling plus breadcrumbs are brown, 15–20 minutes longer. Leave to sit 10 minutes before serving.
