Classic Ratatouille Byaldi Recipe
Ingredients
Base sauce
Vegetable layers
Optional additions
Instructions
- Prepare the sauce base
Heat olive oil in a large skillet over medium heat, add the chopped onion, and cook until soft and translucent, stirring often. Add the minced garlic and cook for another minute, then stir in the crushed tomatoes, tomato paste, thyme, oregano, salt, pepper, and red pepper flakes if using. Let the sauce simmer gently for 15 to 20 minutes to deepen in flavor, stirring occasionally, then adjust seasoning.
- Preheat the oven and prepare the baking dish
Preheat your oven to 375°F and spread a thin layer of sauce on the bottom of a 9 by 13 inch baking dish to prevent sticking and add extra flavor.
- Slice the vegetables evenly
Using a mandoline or a very sharp knife, slice the eggplant and zucchini into thin, consistent rounds so they cook evenly and stack beautifully.
- Sauté or roast the vegetable slices
Lightly brush both sides of the eggplant and zucchini slices with olive oil, season with salt and pepper, and either sauté them in a hot skillet for a few minutes per side or roast them on a baking sheet for about 10 minutes until just tender.
- Arrange the vegetables in a spiral pattern
Start with a ring of eggplant slices along the outer edge of the sauce coated dish, then layer zucchini slices, overlapping slightly, moving toward the center in a neat spiral. Tuck in red bell pepper strips and any optional mushrooms or squash for color and texture.
- Bake until the vegetables are tender
Cover the dish with foil and bake for 25 minutes, then remove the foil and bake for another 10 to 15 minutes until the edges are bubbling and the top vegetables are lightly golden.
- Finish with seasoning and fresh herbs
Taste the ratatouille and add a little more salt or pepper if needed, then scatter over fresh basil or parsley for a bright, garden fresh finish.
- Rest before serving
Let the byaldi rest for 5 to 10 minutes so the layers set slightly, making it easier to portion neat slices and serve the glossy sauce.
Substitutions and variations
- Use gluten free breadcrumbs or crushed gluten free crackers for a gluten free version.
- Swap fresh tomatoes for high quality canned San Marzano tomatoes in the sauce.
- Substitute dried herbs with 1 tablespoon fresh herbs per teaspoon dried if you prefer a brighter flavor.
- Make it vegan by using olive oil instead of butter and skipping any optional cheese garnish.
Chloe's tips
- For extra flavor, roast the eggplant and zucchini on a sheet pan first so they hold their shape and add a deeper taste to the dish.
- Take your time slicing the vegetables as thinly and evenly as possible; this makes the dish look restaurant quality and helps everything cook through.
- If you like a richer sauce, stir in a small knob of butter at the end or sprinkle a little grated Parmesan over the top before serving.
How to store it
- Cool completely, then store in an airtight container in the refrigerator for up to 3 to 4 days.
- Reheat gently on the stovetop or in a low oven until warmed through to keep the vegetables tender and saucy.
- The flavors often improve overnight, so consider making it a day ahead for an even more vibrant ratatouille.
Serving suggestions
Serve this beautiful byaldi sliced straight from the pan, accompanied simply by crusty bread or a light salad.
