Directions for Baked White Fish with Lemon Garlic and Roasted Potato Medley
Follow these simple one-pan steps to prepare your Baked White Fish with Lemon Garlic and Roasted Potato Medley:
- Roast the Potatoes: Preheat your oven to 400°F (200°C). On the large baking sheet, toss the halved baby potatoes with 2 tablespoons of olive oil, salt, and pepper. Arrange them in a single layer.
- First Roast: Roast the potatoes for 20-25 minutes, or until they are beginning to get tender and golden.
- Prepare the Fish and Sauce: While the potatoes are roasting, pat the fish fillets completely dry with a paper towel and season both sides with salt and pepper. In a small bowl, whisk together the melted butter, lemon juice and zest, minced garlic, chopped parsley, and optional red pepper flakes.
- Combine and Add Fish: Remove the baking sheet from the oven. Push the potatoes to the sides of the pan to create space. Place the fish fillets in the center of the pan. If using, scatter the cherry tomatoes around the potatoes.
- Add Sauce and Bake: Pour the prepared lemon garlic sauce evenly over the fish fillets and the potatoes.
- Final Bake: Return the pan to the oven and bake for another 12-15 minutes. The Baked White Fish is done when it is opaque and flakes easily with a fork. The potatoes should be fully tender.
- Garnish and Serve: Garnish the entire pan with a sprinkle of fresh parsley. Serve your Baked White Fish with Lemon Garlic and Roasted Potato Medley immediately.

Tips and Variations
- Best Fish to Use: This recipe works well with any firm white fish. Cod, haddock, halibut, pollock, or tilapia are all great choices.
- Add Other Veggies: Quick-cooking vegetables like asparagus spears, zucchini slices, or bell peppers can be added to the pan along with the fish.
- Use Parchment Paper: Lining your baking sheet with parchment paper will prevent the fish from sticking and makes cleanup a breeze.
- Herb Variations: Feel free to add other fresh herbs to the sauce, such as dill or thyme, which both pair beautifully with fish.
- Don’t Overcook: The key to tender fish is to not overcook it. Keep a close eye on it; it’s done as soon as it flakes easily.

FAQs
1. How can I tell when the fish is cooked?
The fish is cooked when its color changes from translucent to opaque and it flakes easily when gently pressed with a fork.
2. Can I use frozen fish fillets?
Yes, but you must thaw them completely first. Pat them very dry before seasoning to ensure they bake properly and don’t become watery.
3. What if I don’t have baby potatoes?
You can use larger potatoes like Yukon Golds or red potatoes. Just be sure to cut them into uniform 1-inch cubes so they cook evenly.
4. Can I prepare this ahead of time?
You can chop the potatoes and make the sauce ahead of time. However, it’s best to bake the dish right before you plan to serve it, as fish is best enjoyed fresh.
5. Is this recipe gluten-free and dairy-free?
It is naturally gluten-free. To make it dairy-free, simply substitute the butter with a good quality olive oil or a dairy-free butter alternative.
6. My sauce looks separated. Is that normal?
Yes, a simple butter and lemon sauce can sometimes separate a bit while baking. Just give everything a gentle stir on the pan or spoon some of the sauce from the pan over the fish and potatoes before serving.
