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. Add the peeled and chopped eggplant, stirring often to ensure even cooking. Sauté until the eggplant pieces turn lightly browned and tender. This step is essential because it softens the eggplant and lets it soak up all those wonderful flavors later in the dish. Once done, remove the eggplant from the pan and set it aside.
Step 2: Sauté the Zucchini
Add the remaining 1 tablespoon of olive oil to the pan, then toss in the zucchini or yellow squash pieces. Cook them for about 5 minutes until they develop the slightest golden edges and become tender. This preserves their freshness and prevents them from turning mushy later on. Remove the zucchini from the pan and set aside with the eggplant.
Step 3: Cook the Onions and Peppers
If your pan looks a bit dry, add just a touch more olive oil. Then throw in the diced onions and bell peppers. Sauté these vibrant veggies for roughly 5 minutes until they soften and release their natural sweetness. These aromatics form the flavorful base of your ratatouille, so be patient and let them work their magic.
Step 4: Add Tomatoes and Spices
Next, stir in the diced Roma tomatoes along with fresh thyme, kosher salt, ground black pepper, and crushed red pepper flakes if you want a subtle heat. Cook everything together for 5 minutes to meld the flavors and soften the tomatoes, allowing them to release their juices that create the signature sauce.
Step 5: Simmer with Eggplant and Zucchini
Return the sautéed eggplant and zucchini to the pan. Partially cover the skillet or Dutch oven and reduce the heat to low. Let the ratatouille simmer gently for 30 to 40 minutes, stirring occasionally. This slow cooking melds the vegetables beautifully, resulting in tender, melt-in-your-mouth textures and a harmonious flavor blend that makes Nanou’s Authentic Ratatouille Recipe truly unforgettable.
Step 6: Finish with Fresh Herbs
Just a couple of minutes before serving, stir in the chopped parsley and basil. These fresh herbs add a burst of color and brightness that lifts the dish to new heights. At this point, taste and adjust the seasoning to your liking—it’s all about creating a perfectly balanced medley that feels like a warm hug on a plate.
