Plan on 15 minutes of preparation and 35 minutes of cooking time. There is no separate resting time, so this comforting dinner can go straight from the oven to the table.

Step 1: Preheat the Oven

Preheat your oven to 425°F. Let it heat fully while you prepare the baking dish and ingredients.

Step 2: Add the Potatoes

Place the halved baby potatoes in a large baking dish. Arrange them in a fairly even layer so they roast nicely.

Step 3: Toss with Oil

Drizzle the potatoes with 1 tablespoon of olive oil. Toss gently until the cut sides are lightly coated.

Step 4: Roast the Potatoes

Roast the potatoes for 20 minutes. This gives them a head start so they become tender and golden while the fish cooks.

Step 5: Make the Lemon Garlic Butter

In a small bowl, whisk the melted butter, remaining olive oil, garlic, lemon juice, dried parsley, paprika, salt, and black pepper. Stir until the mixture is well combined.

Step 6: Arrange the Fish

Carefully remove the baking dish from the oven and arrange the fish fillets over the roasted potatoes. Keep the fillets in a single layer for even cooking.

Step 7: Add the Sauce

Pour the lemon garlic butter evenly over the fish. Let a little sauce run onto the potatoes for extra flavor.

Step 8: Add Tomatoes and Lemon

Scatter the cherry tomatoes and lemon slices around the fish. The tomatoes will soften and release their juices as they bake.

Step 9: Bake the Fish

Return the dish to the oven and bake the fish for 12 to 15 minutes. The exact time will depend on the thickness of the fillets.

Step 10: Check the Temperature

Check the thickest part of the fish with an instant-read thermometer. It should reach 145°F for safe serving.

Step 11: Add Fresh Parsley

Sprinkle the baked fish and vegetables with the chopped fresh parsley. This adds a lovely fresh finish and a pretty touch of color.

Step 12: Serve Warm

Serve the fish warm with the roasted potatoes and tomatoes. Spoon any lemon garlic butter from the dish over each serving.

Pro Tips for Making Easy Fish Recipes For Dinner

  • Choose fish fillets that are similar in thickness so they finish cooking at about the same time.
  • Pat the fish dry before adding it to the dish. This helps the lemon garlic butter cling to the fillets.
  • Cut the potatoes into evenly sized pieces so they roast at the same rate.
  • Begin checking the fish at 12 minutes, since thinner fillets may cook quickly.
  • Use an instant-read thermometer in the thickest part of the fish to confirm it reaches 145°F.

Make Ahead and Storage

Storing Leftovers

  • Let leftovers cool promptly, then place them in a covered container and refrigerate within 2 hours.
  • Store the fish and vegetables in the refrigerator for up to 3 days.
  • Keep the fish with the pan juices to help it stay moist.

Freezing

  • For the best texture, enjoy the fish fresh rather than freezing it after baking.
  • If needed, freeze cooled fish and vegetables in an airtight freezer-safe container for up to 1 month.
  • Thaw overnight in the refrigerator before reheating.

Reheating

  • Reheat leftovers in a covered baking dish at 325°F until warmed through.
  • Add a small splash of water or a little butter before reheating to help prevent dryness.
  • Reheat only the portion you plan to eat, since repeated reheating can make fish tough.

What type of fish works best for this recipe?

Firm white fish such as cod or haddock works beautifully. Choose fillets with a similar thickness so they cook evenly.

Can I use frozen fish?

Yes, thaw the fish completely in the refrigerator and pat it dry before baking. Removing excess moisture helps the sauce cling to the fillets.

How do I know when the fish is done?

The thickest part should reach 145°F when checked with an instant-read thermometer. The fish should also look opaque and separate easily with a fork.

Can I add other vegetables?

Yes, you can add quick-cooking vegetables such as sliced zucchini, bell peppers, or green beans. Cut them into pieces that will cook in the same time as the fish.
