Step-by-Step Instructions
Prepare the Ingredients:
Rinse the mackerel fillets under cold water and pat them dry with paper towels.
Chop the onion, mince the garlic, and measure out the diced tomatoes and herbs.
Sauté the Aromatics:
In a large skillet, heat the olive oil over medium heat.
Add the chopped onion and sauté for about 5 minutes until softened and translucent.
Stir in the minced garlic and cook for another minute until fragrant.
Add the Tomatoes and Seasoning:
Pour in the diced tomatoes along with their juices.
Add the dried oregano, salt, and pepper. Stir to combine, then bring the mixture to a simmer.
Cook the Mackerel:
Gently place the mackerel fillets skin-side down into the sauce.
Spoon some of the sauce over the fillets to keep them moist.
Cover the skillet and let the fish cook for about 10-15 minutes, or until the mackerel is cooked through and flakes easily with a fork.
Finishing Touches:
Once cooked, remove the skillet from heat and let it stand for 5 minutes.
Garnish with fresh basil leaves and serve with lemon wedges on the side for an extra zing.
Variations
Herb Variations: You can use fresh herbs like thyme or parsley instead of oregano for a different flavor profile.
Spicy Twist: Add red pepper flakes to the sauce for some heat.
Vegetarian Option: Substitute mackerel with hearty vegetables like eggplant or zucchini, cooking them in the sauce until tender.
