Step‑by‑Step Instructions for Cod with Ratatouille
Step 1: Prepare the Ingredients
Start by patting the cod dry with paper towels, then season both sides with salt, black pepper, and sweet paprika. Next, chop the zucchini, yellow bell pepper, fennel bulb, and shallot into bite-sized pieces, and mince the garlic cloves. Having your ingredients ready will make the process smooth as you embark on making this delicious cod with ratatouille.
Step 2: Sear the Cod
In a large skillet, heat 2 tablespoons of olive oil and 1 tablespoon of unsalted butter over medium-high heat. Once the butter is melted and begins to bubble, gently place the seasoned cod loins in the skillet. Sear for about 3 minutes on each side until golden and flaky. Once done, transfer the cod to a plate and set it aside, allowing the flavors to meld together.
Step 3: Sauté the Vegetables
In the same skillet, add the chopped zucchini and sauté for approximately 3 minutes until it starts to soften. Next, toss in the bell pepper and fennel, cooking for another 3 minutes until they become tender. Add the minced garlic and shallot, continuing to sauté for an additional 2 minutes until fragrant. This vibrant vegetable mix is essential for your ratatouille.
Step 4: Incorporate Spices and Tomato Base
Stir in the herbes de Provence, tomato paste, and halved cherry tomatoes with the sautéed vegetables. Pour in 1 cup of vegetable broth, bringing the mixture to a gentle boil. Once the dish bubbles, reduce the heat to low and let it simmer uncovered for about 10 minutes. The ratatouille will begin to meld together beautifully, creating a rich sauce for your cod.
Step 5: Combine and Finish Cooking
After the ratatouille has simmered, return the seared cod to the skillet. Top it with 1 tablespoon of capers, allowing the flavors to blend. Cover the skillet and simmer for an additional 3 minutes, or until the cod is heated through and flaky. The harmonizing of the cod with the robust ratatouille creates an irresistible finish to this hearty meal.

How to Store and Freeze Cod with Ratatouille
Fridge: Store leftovers in an airtight container for up to 3 days. This keeps your healthy cod with ratatouille fresh and flavorful for a quick meal later.

Make Ahead Options
Preparing Cod with Ratatouille in advance is a fantastic way to save time on busy weeknights! You can chop all the vegetables and even season the cod up to 24 hours ahead, placing them in airtight containers in the refrigerator to maintain freshness. The ratatouille base can be cooked and stored in the fridge for up to 3 days, allowing the flavors to deepen. When you’re ready to serve, simply reheat the ratatouille and then add the seared cod back in to warm through for about 3 minutes. This approach ensures you enjoy delicious, restaurant-quality results with minimal effort and time on your hands.
