Ingredients You’ll Need
This dish keeps things simple but full of character, leaning on fresh herbs and pantry staples to build flavor. It’s one of those easy mediterranean diet recipes that shows how a few thoughtful ingredients can create something truly special.
- Extra virgin olive oil (2 tablespoons): This is the foundation of the sauce, adding richness and helping soften the onions. The amount ensures the vegetables cook properly without becoming greasy.
- Large yellow onion (1, halved and thinly sliced): These slices melt down into the sauce, adding natural sweetness and body. Cutting them into half moons helps them cook evenly and blend into the dish.
- Garlic cloves (2, minced): Garlic adds a punch of savory depth. Mincing ensures it distributes evenly throughout the sauce without overpowering any bite.
- Whole peeled tomatoes (1 can, 28-ounce): These form the heart of the sauce, delivering a rich, slightly tangy base. Using whole tomatoes allows you to control the texture as you break them down.
- Dried oregano (2 teaspoons, plus more for fish): This herb brings a warm, earthy flavor that ties everything together. The quantity ensures the sauce is well-seasoned without being overwhelming.
- Black pepper: Adds gentle heat and balance to the sweetness of the tomatoes and onions.
- White fish filet (2 pounds, such as halibut or cod): The star of the show. A firm white fish holds its shape while baking and absorbs all that beautiful sauce.
- Kosher salt and black pepper: Essential for seasoning both the sauce and the fish, enhancing all the natural flavors.
- Kosher salt (for fish): Helps draw out moisture slightly and seasons the fish throughout for better flavor.
- Dried oregano (1/2 teaspoon for fish): Reinforces the herb flavor directly on the fish so every bite is balanced.
- Sweet paprika (1 teaspoon): Adds a subtle warmth and color without any heat, giving the fish a gentle depth.
- Ground cumin (1/2 teaspoon): Brings a hint of earthiness that complements the tomato sauce beautifully.
- Lemons (2, divided): One lemon is squeezed over the fish to brighten the flavor, while the other is served fresh for that final pop of acidity.
- Fresh parsley (1/4 cup, chopped): Adds a fresh, clean finish and a pop of color right before serving.
Every one of these ingredients plays its part—nothing fancy, just honest, flavorful cooking that comes together like a charm.
There’s something special about a dish like this. It doesn’t ask for much, but it gives you a whole lot in return—flavor, comfort, and that feeling of gathering around something homemade and meaningful.
How to Make Psari Plaki (Baked Fish with Tomatoes and Herbs)
This is one of those dishes that feels like it came straight from a well-loved family kitchen—simple steps, big flavor, and a whole lot of heart. I’ll walk you through it just like I would if you were standing right beside me.
- Preheat the oven to 400°F and position a rack in the middle so everything cooks evenly.
- Cook the sauce by heating olive oil in a large oven-safe pan over medium-high heat. Add the sliced onions with a pinch of salt and cook, tossing regularly, until softened and lightly golden. Add the garlic, then stir in the tomatoes with their juices, breaking them up with a wooden spoon. Season with oregano, salt, and black pepper, then bring to a boil before lowering the heat to simmer for 10 to 15 minutes.
- Season the fish by patting it dry and coating both sides with kosher salt, oregano, paprika, and cumin. Cut one lemon and squeeze it evenly over the fish to add brightness.
- Nestle the fish into the sauce once it’s ready, then spoon some of that rich tomato mixture right over the top so each piece is well covered.
- Bake on the center rack until the fish turns opaque and flakes easily with a fork, checking occasionally to avoid overcooking.
- Finish by sprinkling fresh parsley over the top and serving with lemon wedges from the remaining lemon on the side.
Tips for the Best Psari Plaki (Baked Fish with Tomatoes and Herbs)
- Slice onions evenly: Keeping the onion slices uniform helps them cook at the same rate and blend smoothly into the sauce.
- Break up the tomatoes well: Using a spoon to crush the whole tomatoes ensures a balanced sauce texture that coats the fish nicely.
- Pat the fish dry: Removing excess moisture helps the seasoning stick better and keeps the texture just right.
- Cover the fish with sauce: Spoon the sauce over the top before baking so every bite stays moist and flavorful—perfect for quick mediterranean recipes.
- Check doneness carefully: Since ovens vary, keeping an eye on the fish prevents it from drying out.
Storage & Make-Ahead Tips
Fridge: Store any leftovers in an airtight container in the refrigerator for up to 2 days. For best texture, enjoy it at room temperature rather than reheating, which can overcook the fish.
Freezer: While freezing is possible, the texture of the fish may change slightly once thawed. If you do freeze it, store in a sealed container for up to 3 months and thaw in the refrigerator before serving.
Make-ahead: You can prepare the tomato sauce ahead of time and refrigerate it. When ready to serve, reheat the sauce, add the seasoned fish, and bake as directed.
Frequently Asked Questions
Q: What type of fish works best for Psari Plaki?
Firm white fish like cod or halibut works best because it holds its shape during baking and absorbs the flavors of the sauce without falling apart. The recipe is designed for these types of fish, ensuring a tender but sturdy texture once cooked.
Q: How do I know when the fish is fully cooked?
The fish is done when it turns opaque and flakes easily when touched with a fork. Since oven performance can vary, it’s helpful to check occasionally toward the end of baking to avoid overcooking.
Q: Can I make the sauce ahead of time?
Yes, the sauce can be made ahead and stored in the refrigerator. When you’re ready to cook, simply reheat it, add the seasoned fish, and bake as instructed. This makes the process even smoother.
Q: Why do I need to pat the fish dry before seasoning?
Patting the fish dry removes excess moisture, which helps the seasoning stick better and ensures the fish cooks properly in the sauce without becoming watery.
Q: Can I adjust the seasoning on the fish?
The seasoning blend provided gives a balanced flavor that complements the sauce. You can slightly adjust salt or pepper to taste, but the combination of oregano, paprika, and cumin is key to the dish.
