Hands-on Time
15 Mins
Total Time
48 Mins
Serves 4 (serving size: 1 fillet, 2 tomato halves, and 3/4 cup green beans)

Green beans steam in their own sealed packet while tomatoes slowly roast and panko-crusted tilapia gets nicely crisp on top, all on a single baking sheet.

How to Make It

Step 1

Preheat oven to 500°.

Step 2

Place tomatoes, cut sides up, on a foil-lined baking sheet coated with cooking spray. Coat tomatoes with cooking spray; sprinkle evenly with 1/4 teaspoon salt and 1/4 teaspoon pepper. Bake at 500° for 5 minutes.

Step 3

Reduce oven temperature to 450° (do not remove pan from oven). Combine 1/4 teaspoon salt, oil, garlic, and green beans on a large piece of foil; toss to coat. Fold foil over, and seal tightly to form a packet. Place packet on baking sheet with tomatoes; bake at 450° for 20 minutes.

Step 4

Combine mayonnaise, juice, tarragon, and Dijon in a bowl, stirring with a whisk. Sprinkle fillets evenly with remaining 1/4 teaspoon salt and remaining 1/4 teaspoon pepper. Spread mayonnaise mixture evenly over 1 side of fillets. Top evenly with panko, and coat with cooking spray.

Step 5

Remove pan from oven. Move tomatoes and packet to 1 side of pan. Arrange fillets on other side of pan. Bake at 450° for 6 minutes. Turn broiler to high (do not remove pan from oven). Broil 3 minutes or until panko is golden and fish flakes easily when tested with a fork. Serve with green beans, tomatoes, and lemon.

Easy to put together and quite tastey. My husband only wants green beans like this from now on.

This was delicious; everything, the fish, tomatoes and green beans. Didn't change anything, made exactly as written. I'd definitely serve this to guests. Served with a warm whole wheat roll.

I did not make the veggies because we had a salad. The fish was delicious. I did not have the fresh herbs, so I used flavored panko. Quick and easy weeknight dinner.

The fish was great tasting and easy. I used Wegmans basting oil on beans. Tomatoes could have used something more. Would make again-takes a bit long but easy prep.

This was incredible and all is done on one baking tray.  I cut the tomatoes and got the green beans ready at the same time while the oven preheated.  I used pre-minced garlic to save time.  I chopped the tarragon and got the fish ready while the other stuff baked.  Overall very very pleased.  It is a beautiful presentation too!  I will be making this for company! 

Absolutely Delicious!!

Everything about this meal was fantastic!! Beautiful seasoning on the tilapia ... I timed it exactly as written and it was perfect (I used tilapia loins). The green beans were amazing with a delicate garlic flavor and the tomatoes where out of this world (I will double the tomatoes next time they were so good!) I did not change a thing in the recipe and it was perfection!

Tasty and easy!

This was really easy to make and required very little prep work, which was nice. I had plenty of time to prep the green beans while the tomatoes started roasting and even more time to prep the fish while the veggies cooked. I used French style green beans, but made everything as written. The tomatoes were sweet, the beans took on a really nice garlic flavor and the fish was moist, delicious, and flavorful. 

The best tilapia I've ever made

This tilapia recipe is amazing.  So simple and delicious.  The tarragon mayonnaise adds great flavor and binds the crisp panko crust on top.  The fish was so moist and flavorful.  The tomatoes were also a hit, although the green beans needed more time in the packet (and I even used the thinner haricot verts).  Cleanup was a breeze with the foil-lined single pan.  My husband and I were raving as we ate this; it will definitely make it into our regular rotation. 

Fantastic, he said!

My picky spouse loves this recipe.  In fact, he commented on it several times during the meal which is really unusual.  The recipe is easy, and delicious, and cleanup was a snap.  Lets make more one-dish meals!

Great seafood and veggies oven meal

I like that this meal can be prepared all in one pan in the oven.  Love the way the green beans come out not soft and overdone.  Can't wait to try this on the grill in the summer.  This has become a regular on our menus and can be made with different types of fish.
