Mediterranean Baked White Fish will quickly become your go-to for easy dinners bursting with flavor. The bright mix of lemon juice tomatoes olives and herbs turns simple white fish into a lively meal that feels both healthy and a little special. Quick to pull together and vibrant on the plate it is the ultimate weeknight hero.
This became a staple for me one summer when I needed fast dinners after long days at work. My family raves about the juicy tomatoes and how the house smells as it bakes.
Ingredients
- White fish fillets such as cod or halibut: Look for fillets about one to one and a half inches thick for perfect cook time
- Extra virgin olive oil: Adds richness and helps create a golden top Use the best quality you can
- Fresh lemon juice: Lifts the flavors and brightens the whole dish
- Cherry tomatoes: Choose ripe firm tomatoes for bursts of sweetness
- Pitted olives: Kalamata or green both bring briny tang and color
- Red onion: Offers gentle sharpness Choose firm onions without bruises
- Garlic cloves: Minced garlic brings depth and warmth
- Fresh thyme leaves: Delivers herbal notes Use fresh for best results
- Dried oregano: Adds that classic Mediterranean flavor Make sure it is aromatic and not faded
- Salt and pepper: To season and finish Go easy since olives are salty
Step-by-Step Instructions
- Heat the Oven:
- Preheat your oven to four hundred twenty five degrees Fahrenheit Set a rack in the center to ensure even cooking
- Prepare the Fish:
- Pat the fish dry on both sides with a paper towel to help it bake evenly Sprinkle salt and pepper all over both sides This boosts the flavor in every bite Place the fish in a lightly oiled baking dish and squeeze fresh lemon juice over the top
- Mix Toppings:
- In a mixing bowl add the halved cherry tomatoes chopped olives minced red onion and minced garlic Sprinkle in the fresh thyme and dried oregano Add a small pinch of salt and ground pepper and about three tablespoons of olive oil Toss well so everything is coated
- Top the Fish:
- Spread the tomato and olive mixture evenly over the fillets in the baking dish Try to cover the fish for the juiciest result
- Bake:
- Place the dish in your hot oven Bake for fifteen to twenty minutes until the fish is opaque and flakes with a fork If your fish is thinner check early to prevent overcooking
- Serve:
- Remove from the oven and spoon some of the flavorsome juices over each piece Serve immediately with extra lemon if you love the tartness

I cannot resist good olives and always mix green and kalamata for a pop of color and taste. My little one once helped scatter the tomatoes and still swears the bursts of juice are the best surprise in every bite.
Storage Tips
Store leftovers in an airtight container in the refrigerator for up to two days. Gently reheat in the oven or enjoy cold over salad.
Ingredient Substitutions
Snapper tilapia or haddock all work if you cannot find cod or halibut. For olives try only one kind if that is all you have on hand. Out of fresh thyme then parsley or basil gives its own spin.
Serving Suggestions
This is wonderful over lemon rice or simple couscous. Add a big green salad and maybe some crusty bread to soak up the juices. I love plating it family style for weeknight gatherings.
