How to Make Nanou’s Authentic Ratatouille Recipe
Step 1: Sauté the Eggplant
Start by heating 2 tablespoons of olive oil in a large skillet or Dutch oven over medium-high heat. Toss in the peeled and chunked eggplant and sauté it, stirring frequently, until each piece is lightly browned and tender. This step ensures the eggplant develops a lovely texture, absorbing flavors beautifully later on. Once done, remove the eggplant from the pan and set it aside to keep warm.
Step 2: Sauté the Zucchini
Add the remaining tablespoon of olive oil to the pan, then add the zucchini cubes. Let them cook for about 5 minutes until they’re golden and softened. The zucchini adds a subtle sweetness and a tender bite that’s crucial for the overall harmony of this dish. When ready, remove from the pan and set aside just like the eggplant.
Step 3: Sauté Onions and Peppers
If your pan looks dry, drizzle a bit more olive oil in and add the diced onions along with your bell peppers. Softening these veggies, about 5 minutes, builds the foundational flavors, and the natural sweetness from the onions and peppers enriches the ratatouille’s character.
Step 4: Add Tomatoes and Spices
Now, stir in the perfectly diced Roma tomatoes, fresh thyme, kosher salt, ground black pepper, and if you love a gentle heat, sprinkle in the crushed red pepper flakes. Let this mixture simmer and meld together for 5 minutes. During this time, you’ll notice the mixture thickening slightly, turning into a fragrant, chunky base for your stew.
Step 5: Simmer the Ratatouille
Return the sautéed eggplant and zucchini to the pot. Give everything a good stir, cover partially with a lid, reduce the heat to low, and let it simmer gently for 30 to 40 minutes. Stir occasionally to keep the veggies from sticking and to encourage all those fresh flavors to mingle into a tender, cohesive dish.
Step 6: Finish with Fresh Herbs
Just before you’re ready to serve, stir in the chopped fresh parsley and basil. These vibrant herbs bring a burst of freshness and a finishing aroma that elevates Nanou’s Authentic Ratatouille Recipe to something truly special. Taste the stew and adjust salt or pepper if needed.
How to Serve Nanou’s Authentic Ratatouille Recipe

Garnishes
This ratatouille shines with simple garnishes. A sprinkle of extra fresh basil or a drizzle of good quality extra virgin olive oil right before serving adds an irresistible aroma and rich mouthfeel. Some toasted pine nuts or a crumble of feta cheese can also add a delightful textural contrast.
Side Dishes
Nanou’s Authentic Ratatouille Recipe pairs beautifully with many sides. Try serving it alongside crusty French bread to soak up the flavorful juices or over a bed of fluffy couscous for a more substantial meal. It also complements grilled meats or roasted chicken wonderfully if you prefer a protein on the side.
Creative Ways to Present
Impress your guests by serving this ratatouille layered in a shallow baking dish and topped with thin slices of vegetables arranged in a pretty pattern before cooking. Alternatively, serve it in individual bowls with a dollop of creamy goat cheese or a poached egg to add richness and a touch of elegance.
Make Ahead and Storage
Storing Leftovers
Ratatouille tastes even better the next day as the flavors have more time to develop. Store leftover ratatouille in an airtight container in the refrigerator and enjoy it within 3 to 4 days. It’s perfect for quick lunches or easy dinners during the week.
Freezing
You can absolutely freeze Nanou’s Authentic Ratatouille Recipe. Let it cool completely, then portion it into freezer-safe containers or heavy-duty zip bags. Freeze for up to 3 months. When you’re ready, thaw overnight in the fridge and reheat gently on the stove to maintain that fresh, vibrant flavor.
Reheating
To bring leftovers back to life, reheat slowly over low heat on the stove, stirring occasionally. This ensures that the vegetables stay tender without losing their shape or becoming mushy. You can also reheat in the microwave, but be careful to warm gently and evenly.
FAQs
Can I use canned tomatoes instead of fresh Roma tomatoes?
Absolutely! Canned diced tomatoes work well if fresh ones aren’t available. Choose a good-quality can with no added flavors for the best results, and drain excess liquid to avoid a watery stew.
Is Nanou’s Authentic Ratatouille Recipe vegan?
Yes, this recipe is entirely plant-based and vegan-friendly as it is made solely from vegetables, herbs, and olive oil with no animal products involved.
Can I prepare ratatouille in advance?
Definitely! In fact, ratatouille often tastes better the next day after the flavors have melded. You can make it a day ahead and simply reheat before serving.
What’s the best way to peel an eggplant?
The easiest method is to use a vegetable peeler to remove the skin in long strips. Peeling reduces bitterness and helps the eggplant soften evenly in the stew.
Can I add other vegetables to Nanou’s Authentic Ratatouille Recipe?
Of course! While the traditional recipe focuses on specific vegetables, feel free to add mushrooms, carrots, or even potatoes, but keep in mind this may slightly change the texture and cooking times.
