    This easy dinner of Roasted Mahi Mahi with Green Beans and Cherry Tomatoes gets a kick with a lemony vinaigrette.   It will become one of your favorite sheet pan suppers!

    Scalloped plate with fish, green beans and tomatoes.

    Healthy sheet pan suppers have become my favorite thing to cook.  They are so easy to prepare and so easy to modify.   

    All you need to do is check on the individual roasting times for your vegetables and your protein.  Then you simply start with the longest roasting item and then add each additional food, so that they all finish at the same time.

    Once you have everything roasted, you can serve it as is or you can make a quick vinaigrette like I did for this recipe.  It adds a little freshness at the end and brightens the flavors.

    Two plates with mahi mahi and green beans and tomatoes

    Ingredients

    Green Beans

    Cherry Tomatoes - could use regular tomatoes, just dice them.

    Red Chili Pepper - seeded if you don't want heat.

    Mahi Mahi filets - I used frozen that I thawed.

    Olive oil, salt and pepper, lemon juice and Dijon Mustard - for dressing.

    Instructions

    Preheat oven to 400. You want a nice hot oven.

    Place green beans, red chili and tomatoes on a baking sheet. Keep the green beans and tomatoes separate, if you want to serve them like I have in the photo. Drizzle with olive oil and sprinkle with salt and pepper. Roast for 10 minutes.

    While the vegetables are roasting place the Place Mahi Mahi on one baking sheet, drizzle with olive oil and salt and pepper.

    After 10 minutes add the mahi mahi to the oven and continue to roast the vegetables and the fish for 10 more minutes.

    While everything is roasting, in a small mason jar combine 1 tablespoon of olive oil, 1 tablespoon of lemon juice and 1 teaspoon of Dijon mustard. Put a lid on it and shake and until creamy.

    Note that I used two baking sheets for this.  I wanted to be able to spread out the green beans and the tomatoes so that they roasted and didn't steam.   Crowding the baking sheet will cause food to steam, you need to allow air to circulate around the food so it can brown.

    To serve, divide the green beans between two plates. Top with the fish and then the cherry tomatoes. Drizzle with the vinaigrette.

    So easy and so delicious! This simple pan roasted fish is the perfect weeknight dinner!

      Beautiful and simple but very well written instructions. Thank you for this gorgeous dinner idea. Ps. I’m a planner too but usually those throw-the-fridge-open-and-iron-chef-it-out meals are the best!

      Mahi Mahi is not something I could buy in France but I think that most firm white fish would be delicious with this combination!

      We don't really get mahi mahi here. It's a recreational fish rather than a commercial one. Looks tasty.

      Yep, that's going on the summer rotation. Not sure we get mahi mahi here but I'd substitute snapper.

      I love clean out the CSA meals like this!! I have been terrible about using up all my goodies lately (like...I am drowning in my potatoes) so this is definitely inspirational.
