I often make baked perch fillets, especially when I find a bag of fillets in the freezer that I had forgotten about. I love that it doesn’t require much effort, and the vegetables cook alongside the fish, with no extra dishes to wash. The recipe is quick, and there’s nothing complicated to clean up afterward.
Quick Info
Total time: 1 hour
Servings: 4
Difficulty: easy
Ingredients
800 g frozen perch fillets
4-5 medium potatoes
3-4 small zucchini
4-5 garlic cloves
1 lemon
salt
dried oregano
olive oil, about 4-5 tablespoons
Preparation Method
1. Place the perch fillets in a colander to thaw. Leave them there for at least 30 minutes or until they soften and no longer have ice on them. You can gently pat them dry with a towel afterward.
2. In the meantime, peel the potatoes and zucchini. Slice the potatoes thinly, about 0.5 cm thick. You can cut the zucchini into rounds or lengthwise, according to your preference. Peel and roughly slice the garlic.
3. In a large baking dish, arrange the potatoes, zucchini, and garlic. Sprinkle with salt, oregano, and add about 3 tablespoons of olive oil. Mix everything directly in the dish to coat the vegetables with oil and spices.
4. Spread the vegetables into as even a layer as possible. Place the perch fillets on top (dry them lightly with a towel if they are watery). Drizzle the fish with lemon juice (I use about half a lemon, saving the rest for serving), a little olive oil, and a bit more salt and oregano.
5. Put the dish in the oven at 190-200°C on the middle rack. Bake for 35-40 minutes. In my experience, the potatoes cook around the same time as the fish. If you are using thick fillets, check after 30 minutes. The fish should be opaque and flake easily with a fork, and the potatoes should be easily pierced.
6. If you want a browner crust on the fish or vegetables, turn on the grill for the last 5 minutes. Make sure the fish doesn’t dry out.
Why I Make This Recipe Often
I often choose this recipe because it’s quick and almost cooks itself in the oven. There aren’t many ingredients, and there’s no need to fry anything. It works well with both fresh and frozen fillets. It’s easy to portion, and it remains just as good the next day.
Tips and Variations
Tips
- Frozen fillets need to be well-drained. If they remain watery, they will release liquid in the dish, and the vegetables won’t brown but will steam instead.
- Thinly sliced potatoes will definitely cook during the fish. If you have very large potatoes, you can cut them into small cubes.
- Oregano gives a Mediterranean flavor, but don’t use too much, so it doesn’t overpower the taste of the fish.
Substitutions
- Instead of perch, you can use cod, pike, salmon, or any white fish fillet. Cooking times may vary slightly.
- Potatoes can be replaced with sweet potatoes or parsnips for a different texture.
- Oregano can be substituted with thyme or basil if you prefer.
Variations
- You can add other vegetables, such as bell peppers, red onions, or cherry tomatoes.
- For a different flavor, add some sliced black olives on top before putting the dish in the oven.
- If you want a crust, you can sprinkle breadcrumbs or a bit of Parmesan over the fish before baking.
Serving Ideas
- I like to serve the perch fillet with extra lemon slices and a simple green salad.
- It pairs well with a garlic yogurt sauce or a bit of melted butter with parsley.
Frequently Asked Questions
1. Can I use fresh fish fillets instead of frozen?
Yes, fresh fillets do not need to be thawed and will cook a little faster. Check after 25-30 minutes to make sure they don’t dry out.
2. If I don’t have zucchini, what can I substitute?
You can use eggplant, bell peppers, onions, or thinly sliced carrots. Be mindful of cooking times – for example, carrots take longer to cook than zucchini.
3. Can I make the recipe without potatoes?
Yes, if you want it to be lighter or are on a low-carb diet, just use zucchini and your favorite vegetables. The cooking time may even be shorter.
4. What should I do if the fish releases a lot of water in the dish?
If the fillets are very wet, drain them well and pat them with a towel before placing them over the vegetables. If needed, you can drain some liquid from the dish halfway through the cooking time.
5. Can I make the recipe with whole fillets or cut them into pieces?
Either way works. If you have large fillets, you can leave them whole for presentation or cut them into pieces if you want them to cook faster and be easier to serve.
Nutritional Information
One serving has approximately 320 kcal, consisting of:
- protein: 28 g
- fat: 10 g (depending on how much oil you use)
- carbohydrates: 27 g
Perch fillet is relatively low in fat and high in protein. The vegetables add fiber and vitamins. If you reduce the oil or don’t use potatoes, the calories will also decrease.
Storage and Reheating
Cool the leftovers completely, then place them in a sealed container in the refrigerator for up to 2 days. They reheat best in the oven for 10-15 minutes at 160°C, covered with foil to prevent the fish from drying out. You can also use the microwave, but the fish may become a bit drier. I do not recommend freezing it after it has been cooked, as the fish will fall apart.
This recipe is simple, doesn’t leave much mess, and is adaptable for any season or what you have in the fridge. The fish remains tender, and the vegetables absorb flavor from all the juices left in the dish.
