How to Make Rustic Baked Ratatouille Bake

Preheat your oven to 400°F (200°C) to create a perfect baking environment for your delicious casserole. The heat will ensure that everything bakes evenly and the cheese gets beautifully melty.
Dice the eggplant, zucchini, and bell peppers into 1/2-inch cubes. This size ensures they cook uniformly and blend nicely in the casserole, adding texture and flavor.
Chop the onion and mince the garlic. The onion should be finely chopped to enhance flavor distribution, while minced garlic will release its aroma into the dish beautifully as it cooks.
Sauté the onion in a large skillet with olive oil over medium heat. Cook until softened, about 5 minutes, then add the garlic and cook for an additional minute until fragrant.
Add the diced eggplant, zucchini, and bell peppers to the skillet. Cook for 10-15 minutes until slightly softened, stirring occasionally to prevent sticking and promote even cooking.
Stir in the crushed tomatoes, tomato sauce, oregano, basil, and red pepper flakes (if using). Season with salt and pepper, then reduce heat and let it simmer for 10 minutes, allowing the flavors to meld.
Transfer the vegetable mixture to a 9×13 inch baking dish, spreading it out evenly for a consistent bake.
Sprinkle mozzarella over the top, followed by Parmesan. The combination of cheeses creates a delightful golden crust that you won’t be able to resist!
Bake in the preheated oven for 20-25 minutes until the cheese is melted, bubbly, and golden on top. Keep an eye on it to prevent over-browning.
Cool for 5-10 minutes once baked. This waiting period helps the casserole set, making it easier to serve.
Garnish with fresh basil leaves for a pop of color and extra flavor before serving warm.

Optional: Serve with a side of crusty bread to soak up the delicious sauce.

Cheesy Baked Ratatouille Recipe FAQs

How do I choose ripe vegetables for my Cheesy Baked Ratatouille?
Absolutely! When selecting your eggplant, zucchini, and bell peppers, look for firm and shiny skin without dark spots or blemishes. The vegetables should feel heavy for their size and give slightly when pressed, indicating ripeness. For bell peppers, choose bright colors—like red, yellow, or green—or just one color if you prefer a more specific flavor profile.

How should I store leftovers of my Cheesy Baked Ratatouille?
Very! Store leftovers in an airtight container in your refrigerator for up to 3-4 days. Ensure that the casserole cools to room temperature before sealing to preserve its freshness. To reheat, pop it back in the oven; this will keep the cheesy topping perfectly melty.

If your Cheesy Baked Ratatouille seems watery, here’s a quick fix: Before assembling the casserole, after dicing your vegetables, you can salt the eggplant and zucchini and let them sit in a colander for about 30 minutes. This process draws out excess moisture, allowing you to pat them dry with a paper towel before cooking. Also, ensure that you let the dish rest for 5-10 minutes after baking to allow any excess moisture to evaporate.

Absolutely! For a vegan version, simply omit the cheese or substitute with plant-based cheese alternatives. Additionally, if you have allergies, be cautious with the red pepper flakes and adjust the seasonings to suit your needs. This hearty dish is naturally gluten-free, making it a wonderful option for a variety of dietary preferences!
