Cooking Sequence & Checkpoints
Sauté finely diced onion and minced garlic in 2 tbsp olive oil, add diced roasted red peppers, 2 diced Roma tomatoes, half the fresh thyme, kosher salt, and black pepper; simmer 20 minutes until thick and spread across the bottom of the baking dish.
✓ Checkpoint: Thick savory bed of red peppers.
Slice zucchini, yellow squash, Japanese eggplant, and remaining 4 Roma tomatoes into uniform 1.5mm rounds on a mandoline.
✓ Checkpoint: Uniform thin vegetable discs.
Alternate vegetable rounds tightly in concentric circles over the pipérade, working from the outside rim to the center.
✓ Checkpoint: Impeccable colorful shingled pattern.
Drizzle with remaining olive oil, fresh thyme, kosher salt, and black pepper. Cover with a parchment cartouche and bake at 275°F (135°C) for 45 minutes, then remove the parchment and bake at 350°F (175°C) for 15 minutes until tender; finish with aged balsamic vinegar.
✓ Checkpoint: Silky, glistening tender vegetables.
🔬 Why It Works:
Two-Stage Parchment Cartouche Baking (275°F then 350°F): Baking covered with a parchment cartouche at 275°F (135°C) gently confits the vegetables in their own steam, before uncovering at 350°F (175°C) to caramelize the edges.
⚠️ Troubleshooting:
Watery casserole: Simmer roasted pepper pipérade until thick like jam before spreading onto dish.
