Health Benefits & Nutrition
Roasted fish is not only delicious but also packed with nutrients. First, the fish provides lean protein that supports muscle repair and growth. According to the American Heart Association, regular consumption of fish rich in omega-3 fatty acids can lower the risk of heart disease by reducing inflammation and improving cholesterol levels.
Second, fresh herbs like parsley supply antioxidants such as vitamin C and flavonoids, which promote immune health. Third, lemon juice adds vitamin C, boosting iron absorption and enhancing flavor without added calories. Finally, using olive oil delivers heart-healthy monounsaturated fats, which can improve blood vessel function.
Note for expectant mothers or those on blood-thinning medications: anchovy paste, a key ingredient, contains sodium and natural blood-thinning compounds. Moderation and consult with your healthcare provider if unsure.

Full Ingredient List
- 2 large garlic cloves, finely chopped

- 2 teaspoons Dijon mustard
- 1 cup high-quality mayonnaise
- Zest of 2 lemons (about 1 tablespoon)
- 3 tablespoons freshly squeezed lemon juice
- Kosher salt and freshly ground black pepper, to taste
- 3 pounds striped bass steaks, 3/4 to 1 inch thick, cut into 6 portions
- 1/2 cup chopped scallions (white and green parts)
- 2 tablespoons extra virgin olive oil
- 3 tablespoons capers, drained
- Lemon wedges, for serving
Equipment Needed
- Oven preheated to 500°F
- Baking sheet lined with aluminum foil
- Food processor or blender
- Small sauté pan
- Sharp knife and cutting board
- Measuring spoons and cups
Tips for Choosing Quality Ingredients
- Fish: Opt for fresh striped bass steaks with firm, moist flesh that springs back when pressed.
- Mayonnaise: Choose a good-quality mayo without artificial additives for the creamiest sauce.
- Anchovy Paste: Select a brand with pure anchovy flavor and minimal preservatives to enhance umami without overwhelming.
- Fresh Herbs: Use bright green parsley and fresh scallions to maximize aroma and taste.
- Lemons: Pick firm lemons with thin skin for juiciness and intense zest.
Step-by-Step Instructions
Step 1: Preheat and Prep
Set your oven to 500°F and make sure it’s clean to prevent smoke during roasting. Line a baking sheet with aluminum foil for easy cleanup.
Step 2: Make the Caesar Sauce
In a food processor, pulse 2 cloves of garlic, chopped parsley, 1 tablespoon anchovy paste, and 2 teaspoons Dijon mustard until garlic is finely minced — about 15 seconds on high. Add 1 cup mayonnaise, lemon zest, 3 tablespoons lemon juice, 1 teaspoon kosher salt, and 1/2 teaspoon black pepper. Pulse until smooth and creamy, about 20 seconds.
Step 3: Season and Sauce the Fish
Pat dry the striped bass steaks and sprinkle both sides generously with salt and pepper. Reserve one-third of the Caesar sauce for serving. Spread half of the remaining sauce over one side of the fish steaks, flip, and coat the other side with the rest. Top with chopped scallions and let rest for 10 minutes to absorb flavors.
Step 4: Roast the Fish
Arrange the fish on the prepared baking sheet, skin side down if applicable. Roast uncovered for 10 to 12 minutes until the center is just barely cooked through and flakes easily with a fork.
Step 5: Prepare Crispy Capers
While fish rests covered loosely with foil for 10 minutes, heat 2 tablespoons olive oil in a small sauté pan over medium-high heat. Add 3 tablespoons drained capers and cook for 30 to 60 seconds until they start to pop and crisp.
Step 6: Serve
Serve hot fish topped with crispy capers, lemon wedges, and the reserved Caesar sauce on the side. Enjoy the creamy, tangy, and slightly salty textures that perfectly complement the roasted fish.

Variations & Substitutions
- Fish Alternatives: Swap striped bass for halibut, cod, or salmon. Adjust roasting time to fish thickness.
- Mayonnaise Swap: Use Greek yogurt or a mix of yogurt and mayo for a lighter sauce with a tangy twist.
- Anchovy-Free Option: Replace anchovy paste with caper brine for similar umami without fishiness.
- Herb Variations: Add fresh basil or dill to the Caesar sauce for an herbal aroma shift.
- Vegan Version: Use vegan mayonnaise, omit anchovy paste, and substitute fish with thick slices of roasted cauliflower steaks.
Storage & Shelf Life
Store Caesar Roasted Fish in an airtight container in the refrigerator for up to 2 days. For best taste and texture, consume cold or gently reheat in a 300°F oven for 5–7 minutes covered with foil to avoid drying.
Freezing fish after roasting is not recommended due to texture changes unless you freeze raw portions beforehand. Signs the fish has spoiled include a sour smell, slimy texture, or discoloration.
Pro Tips
- Pat the fish completely dry before seasoning to help the sauce stick and to ensure a crispy exterior.
- Letting the fish marinate for 10 minutes allows the Caesar sauce’s acidity to gently firm the flesh and infuse flavor.
- Use a very hot oven (500°F) to achieve a golden, lightly caramelized crust without overcooking.
- Cooking capers until they pop creates a crispy bite that contrasts beautifully with the creamy sauce.
- To avoid staining, handle anchovy paste with a spoon and clean any drips immediately, as it can discolor clothes and surfaces.
