This is one of my favorite weeknight dinners because it comes together in under an hour and tastes absolutely restaurant quality. Fresh mackerel is packed with omega 3 fatty acids that are wonderful for your heart and brain, plus it's incredibly affordable. The crispy lemon herb crust adds such a lovely texture and brightness to the delicate fish, while the green beans roast alongside everything else, making cleanup a breeze. It's simple enough for a busy Tuesday but fancy enough to impress guests, and the whole meal feels light yet completely satisfying.

Instructions
- 1
Preheat oven to 200°C (400°F). Pat the mackerel fillets dry with paper towels and arrange skin-side up on a baking sheet lined with parchment paper.
Tip: Drying the fish ensures the skin gets crispy during roasting.
- 2
In a small bowl, combine panko breadcrumbs, chopped parsley, dill, lemon zest, half the minced garlic, salt, and pepper. Drizzle in 3 tablespoons of olive oil until the mixture resembles damp sand.
Tip: The herb mixture should hold together slightly when pressed.
- 3
Press the herb-breadcrumb mixture firmly onto the skin side of each mackerel fillet, creating an even layer about 5mm thick.
Tip: Work gently to avoid breaking the delicate fish underneath.
- 4
Toss the green beans in a separate bowl with 2 tablespoons of olive oil, remaining garlic, salt, and pepper. Spread them on a second baking sheet in a single layer.
Tip: Use two baking sheets so the green beans can roast at the same temperature without steaming.
- 5
Place both baking sheets in the preheated oven. Roast for 20-25 minutes until the mackerel is cooked through and the herb crust is golden, and the green beans are tender with slightly charred edges.
Tip: The mackerel is done when the flesh flakes easily with a fork.
- 6
While the fish and beans roast, warm butter in a small pan over medium heat. Add the toasted almonds and sauté for 1-2 minutes until fragrant, then remove from heat and stir in lemon juice.
Tip: This warm almond-lemon dressing will be drizzled over the green beans.
- 7
Remove both baking sheets from the oven. Transfer the mackerel fillets to serving plates and arrange the roasted green beans alongside.
Tip: Keep the presentation simple to showcase the quality of the ingredients.
- 8
Drizzle the warm almond-butter sauce over the green beans and serve immediately with extra lemon wedges on the side.
Tip: Serve immediately while the fish is still warm and the herbs are at their most fragrant.

My go to drink for summer gatherings is this refreshing Beergarita, and let me tell you, it's a total crowd pleaser.
