Fish with vegetables can be a great way of ending a long day and starting romantic diner. The combination of fish and various types of low carb vegetables and herbs will make this a super healthy, delicious, and flavorful dish.

While cooking something in oven, you are always at risk of making the food too dry and gummy. Well, there is no need to be afraid with this recipe because you’ll cook the fish fillets in butter, oil and vegetables which will give the fish extra juice.

Moreover, by wrapping the ingredients in foil paper, it will retain all the incredible flavors and keep the food moist. The beautiful taste and fragrance of veggies will soak inside the fish while baking. You will love the smell of it the moment you open the foil bag.

You can use any type of fish for this recipe, preferably boneless and in fillets. Fish such as salmon, cod, barramundi, whiting, perch, etc… Or you can also use other seafood for this recipe such as shrimp.

To make the fish even tastier, try marinating it beforehand in lemon juice and seasonings, garlic and ginger. If you’d like to, you can just leave it overnight in a fridge.

To make it looks more appealing, when choosing vegetables, go for as many different colors as possible. Low carb veggies choices such as zucchini, eggplant, bell pepper in various colors, broccoli, cauliflowers, etc…



Be creative! You don’t have to follow this recipe to a T. You can add extra veggies, herbs and spices or simply work with whatever you have in your kitchen.

Perks of spending so much time cooking something like fish is that later you can reheat it and turn into something else. For example, to cover the same fish with vegetables with melted cheese is a new way to reconstruct yesterday’s diner for today’s lunch.
