Sea Bass on a Bed of Swiss Chard and Browned Rosemary Potatoes

The first time I tasted sea bass prepared simply, yet elegantly, like this, it was at a small trattoria overlooking the Ligurian Sea. The salt air mingled with the scent of rosemary and garlic, and the creamy, delicate sea bass, nestled on a bed of vibrant greens, was a revelation. It was more than just a meal; it was a sensory experience, a taste of pure, unadulterated Italian sunshine, and it’s a memory I try to recreate every time I make this dish.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 25 minutes
• Total Time: 45 minutes
• Servings: 4
• Dietary Type: Pescatarian, Gluten-Free (if using gluten-free flour)

Ingredients

• 1 – 1 ½ lb Chilean sea bass fillet, bones removed, cut into 4 serving pieces
• Salt and Pepper, to taste
• ¼ cup Flour, more if needed
• 4 tablespoons Rosemary oil (or 4 tablespoons Olive oil)
• 1 small Onion, minced
• 4-6 cloves Garlic, minced or pressed, divided
• 1 tablespoon Fresh rosemary, minced
• 4 cups Chopped swiss chard, main stem removed & washed
• 2 large Potatoes or 4 medium Potatoes, peeled and cooked
• 2 Sun-dried tomatoes packed in oil, diced, for garnish

Equipment Needed

• Skillet
• Casserole dish
• Cutting board
• Sharp knife
• Garlic press (optional)
• Mixing bowls

Instructions

1. Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius).

2. Lightly season the sea bass fillets with salt and pepper. Then, gently coat each piece with flour, making sure to shake off any excess. This light dusting of flour will help the fish develop a beautiful golden crust when seared.

3. Heat two tablespoons of rosemary oil (or olive oil) in a skillet over medium-high heat. Once the oil is shimmering, carefully add the sea bass pieces to the skillet. Cook the fish just until lightly browned, about 1 minute on each side. The goal here isn’t to cook the fish through, but rather to create a flavorful crust.

4. Transfer the lightly seared sea bass to a casserole dish. Place the dish in the preheated oven and bake for 10-15 minutes, or until the fish is cooked through and flakes easily with a fork. The cooking time will depend on the thickness of your fillets, so check for doneness around the 10-minute mark.

5. While the fish is baking, return the skillet to the stovetop. Add the minced onion and 3 cloves of minced garlic to the skillet and cook, stirring frequently, until the onion is beginning to soften and become translucent, about 1 to 2 minutes. Be careful not to burn the garlic; it should be fragrant, not bitter.

6. Slice the pre-boiled potatoes into ½ inch thick rounds. Add them to the skillet with the onions, browning them on both sides. Sprinkle with minced rosemary, salt, and pepper to taste. Cook until the potatoes are golden brown and slightly crispy.

7. In a separate pan, heat the remaining two tablespoons of rosemary oil. Toss in the remaining 3 cloves of minced garlic and cook until almost browned, being careful not to burn it. Add the swiss chard to the pan and cook until it is wilted, about 3 minutes. Season with salt and pepper to taste. The swiss chard should be tender but still have a bit of bite to it.

8. To assemble the dish, place the wilted swiss chard on a serving platter. Arrange the cooked sea bass fillets on top of the swiss chard.

9. Arrange the browned potatoes around the swiss chard and sea bass.

10. Sprinkle the diced sun-dried tomatoes over the dish for a burst of sweet and tangy flavor. Garnish with sprigs of fresh rosemary, if desired, for a beautiful and aromatic touch.

Expert Tips & Tricks

• Achieving the Perfect Sear: Make sure your pan is hot before adding the fish. This ensures a good sear and prevents the fish from sticking. Pat the fish dry with paper towels before flouring to promote browning.
• Don’t Overcook the Fish: Sea bass is delicate and can easily become dry if overcooked. Cook it just until it’s opaque and flakes easily with a fork.
• Infusing the Oil: For an extra layer of rosemary flavor, you can infuse the oil by gently heating it with fresh rosemary sprigs before adding the fish or garlic.
• Make-Ahead Prep: The potatoes can be boiled ahead of time and sliced just before cooking. You can also chop the onion, garlic, and swiss chard in advance.
• Substitute for Swiss Chard: If you don’t have swiss chard, you can use spinach, kale, or any other leafy green.

Serving & Storage Suggestions

Serve the sea bass on swiss chard and browned rosemary potatoes immediately for the best flavor and texture. The warmth of the potatoes and the delicate, flaky fish are best enjoyed fresh.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, gently warm the fish and potatoes in a skillet over low heat or in a preheated oven at 300 degrees Fahrenheit (150 degrees Celsius). Be careful not to overcook the fish when reheating. The swiss chard is best enjoyed fresh, but can also be reheated gently. Sun-dried tomatoes add flavor, but omit if sodium levels need lowered.
