There is something genuinely magical about a dinner that looks like a gourmet masterpiece but requires minimal effort. This Mediterranean baked fish brings the vibrant, sun-drenched flavors of the coast right to your kitchen table. Flaky, tender white fish fillets are blanketed in a robust blend of herbs and spices, then nestled in a bed of juicy cherry tomatoes, crisp zucchini, and sweet bell peppers. As it bakes, the tomatoes burst and release their sweet juices, mingling with rich olive oil and zesty lemon to create an elegant, self-basting pan sauce. It is a light, deeply satisfying meal that feels like a celebration of fresh, whole ingredients.

Key Ingredients
I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.
- White Fish Fillets: Cod or halibut work beautifully here. They provide a mild, clean canvas that absorbs the Mediterranean herbs perfectly while staying wonderfully juicy.
- Cherry Tomatoes: These add a beautiful pop of color. As they bake, they burst open to create a naturally sweet, low-carb sauce right in the baking pan.
- Zucchini and Bell Peppers: Sliced thin, these add a wonderful texture and essential nutrients to the dish while keeping the total net carbs very low.
- Extra Virgin Olive Oil: The quintessential Mediterranean ingredient that adds rich, healthy fats and helps roast the vegetables to perfection.
- Lemon and Fresh Herbs: Thick lemon slices and fresh dill bring a bright, sunny acidity and aromatic freshness that cuts through the richness of the oil.
Common Mistakes to Avoid
- Overcooking the fish: Leaving the fish in the oven too long will dry out the delicate fillets; check them early with a fork to ensure they remain flaky.
- Crowding the baking pan: If the vegetables are piled too high on top of one another, they will steam instead of roasting and losing their texture.
- Slicing vegetables too thick: Cutting zucchini or peppers into giant chunks means they won't cook through in the time it takes for the fish to bake.
- Skipping the fresh herbs: Using only dried herbs can result in a muted flavor; the fresh dill and citrus at the end truly bring the dish alive.
Required Equipment
- Large Rimmed Baking Sheet: Provides ample surface area so the fish and vegetables roast evenly together.
- Sharp Chef's Knife: Makes quick work of slicing the zucchini, peppers, and fresh lemons uniformly.
- Small Mixing Bowl: Perfect for whisking together the olive oil, garlic, and dried herbs before coating the fish.
Caleb’s Recipe Tips
- Layer thin lemon slices directly underneath the fish fillets before baking. Trust me, I've learned this the hard way—it prevents the delicate skin from sticking to the pan and infuses extra flavor!
- Pat your fish fillets completely dry with a paper towel before adding any oil or spices. This simple step helps the herb rub stick beautifully and ensures a gorgeous roast rather than a soggy steam.
- Toss the vegetables in olive oil and start roasting them for about 5 minutes before adding the fish if you prefer your peppers extra tender. This head start guarantees everything finishes at the exact same, perfect moment.
- Don't throw away the pan juices left over after baking! Spoon that liquid gold right back over the fish before serving for an instant flavor upgrade.
Storage Instructions
Store any leftover fish and vegetables in an airtight glass container in the refrigerator for up to 2 days. To keep it keto-friendly and preserve the delicate texture, reheat it gently in a skillet over medium-low heat with a tiny splash of olive oil until just warmed through. Freezing is not recommended for this recipe, as the textures of both the delicate white fish and the high-water-content vegetables will become overly soft and mushy upon thawing.
