Step-by-Step Instructions
Step 1: Heat the oven and prep the produce
Preheat the oven to 350°F (175°C). Cut the eggplant into 1-inch chunks and the zucchini into 1/2-inch half-moons. Dice the onion and peppers, and thinly slice the garlic. Crush the canned tomatoes by hand in a bowl, keeping all juices.
Step 2: Salt and drain the eggplant
Spread the eggplant on a sheet pan and sprinkle with 1/2 tsp kosher salt. Toss and let sit for 20 minutes to draw out excess moisture and tame bitterness. Pat dry thoroughly with paper towels just before searing.
Step 3: Sear the eggplant until deeply golden
In a large oven-safe Dutch oven (or heavy skillet), heat 3 tbsp olive oil over medium-high. Add the eggplant in a single layer (work in batches if needed) and cook until well browned on several sides and tender at the edges, 8–10 minutes. Transfer to a bowl.
Step 4: Sear the zucchini
Add 1 tbsp olive oil to the pot. Add zucchini and cook, undisturbed, until the underside is golden, 2–3 minutes; toss and cook 3 minutes more until spotty brown but still firm in the center. Transfer to the bowl with the eggplant.
Step 5: Build a sweet, savory base
Add 2 tbsp olive oil to the pot. Add onion and peppers with a pinch of salt and cook over medium heat, stirring occasionally, until softened and sweet with light golden edges, 10–12 minutes. Stir in garlic, tomato paste, herbes de Provence, and red pepper flakes; cook 1 minute until fragrant. Deglaze with the white wine (if using) and scrape up browned bits.
Step 6: Add tomatoes and reunite the vegetables
Pour in the crushed tomatoes and any juices. Add the bay leaf, balsamic vinegar, and sugar. Return eggplant and zucchini (and any collected juices) to the pot. Season with 3/4 tsp kosher salt and the black pepper; bring to a gentle simmer for 5 minutes.
Step 7: Bake until jammy
Cover the pot and transfer to the oven. Bake for 30 minutes covered, then uncover and bake 15 minutes more, until the sauce is thick and glossy and the vegetables are meltingly tender but still distinct. If your pot isn’t oven-safe, transfer to a covered baking dish for baking.
Step 8: Finish with basil and balance
Remove from the oven and discard the bay leaf. Stir in the basil chiffonade and the remaining 1 tbsp olive oil. Adjust seasoning with additional salt, pepper, and a touch more balsamic if needed. Rest 10 minutes so flavors mingle. Garnish with small basil leaves, a sprinkle of flaky sea salt, and lemon zest (optional). Serve warm with crusty bread, polenta, or your favorite grain.
Pro Tips
- Salt the eggplant: This quick step concentrates flavor and prevents a watery ratatouille.
- Sear in batches: Crowding the pan steams the vegetables; space equals browning and sweetness.
- Oven finish = jammy: The gentle, enclosed heat transforms the tomatoes into a glossy, thick sauce.
- Season in layers: A pinch of salt at each stage builds depth without over-salting at the end.
- Add basil off heat: Fresh herbs stay vibrant and aromatic when stirred in right before serving.
Variations
- Confit Byaldi Style: Slice eggplant, zucchini, and peppers very thin and shingle over the sauce; bake covered 40 minutes, then uncovered 20 minutes.
- Provençal + Chickpeas: Add 1 can (15 oz/425 g) drained chickpeas with the tomatoes and finish with chopped Niçoise olives.
- Spicy Harissa Twist: Swap red pepper flakes for 1–2 tsp harissa paste and finish with a squeeze of lemon.
Storage & Make-Ahead
Cool completely, then refrigerate in an airtight container for up to 5 days or freeze for up to 2 months. Reheat gently on the stovetop over low heat with a splash of water. Flavor improves overnight, so it’s ideal to make ahead. You can also sear the eggplant and zucchini a day early; store separately and combine when ready to cook.
