Here is a one pan weeknight fish dish that’s impressive enough for entertaining. Fresh tomatoes and lemons are layered over the fish with oregano & olives, then topped with fresh basil creating a beautiful flavor-packed, nourishing summer dish. Paleo, gluten free, Whole 30 & keto.
This delicious one pan dish is made with juicy summer tomatoes, lemon and fish roasted in the oven.
As it cooks, the tomatoes soften and become sweeter while the olives add a salty note that goes nicely with the mild flaky fish.
Fresh oregano infuses the fish and tomatoes with a Mediterranean taste. The fresh basil sprinkled on top before serving makes this a summer delight!
I use fluke which is a local fish here on the east end of Long Island. Cod or flounder make fine substitutes, though you may have to adjust the roasting time. The thicker the fillets, the longer they will take to cook.
It’s a simple dish with only 6 ingredients. The combination of the tomatoes, fish, olives, oregano, lemon and basil is an absolute summer favorite.
Hopefully you have fresh herbs growing on your patio or garden. But if you don’t have fresh oregano you can substitute dried but definitely buy fresh basil it’s so good!
Did you know that tomatoes are healthier when they’re cooked?
Cooking enhances the nutritional value of tomatoes. This is because lycopene, the phytochemical that makes them red—is more easily absorbed through the cooking process, which breaks down the plant cell walls, making them accessible.
Of course you can still eat tomatoes raw. Who doesn’t love garden fresh tomatoes, sliced with a sprinkle of salt, pepper and olive oil. Maybe even a little balsamic vinegar. YUM!
Making this beautiful, delicious and nutritious one pan dinner is so easy.
The fish is placed in a casserole dish, sprinkled with fresh oregano, topped with a layer of tomatoes and lemon, olives and a little olive oil, then baked for 8-10 minutes.
Top with fresh basil just before serving.
Dinner is ready in less than 20 minutes.
Serve with roasted potatoes or your favorite grains, and a green salad.
Leftovers store nicely in the refrigerator and can be eaten cold or reheated on the stove.
