This is one of my favorite weeknight dinners because it comes together in under an hour and tastes like you spent all day cooking. Grilled mackerel is wonderfully rich and flaky, and it pairs beautifully with roasted cauliflower in this simple Mediterranean inspired dish. Mackerel is packed with omega 3 fatty acids that are fantastic for your heart and brain health. The best part? Everything roasts on one pan, which means minimal cleanup and maximum flavor. Fresh lemon and thyme brighten up both the fish and vegetables perfectly.

Instructions
- 1
Pat mackerel fillets dry with paper towels and season both sides generously with salt, pepper, and smoked paprika. Set aside at room temperature for 10 minutes.
Tip: Drying the fish helps it develop a crispy skin on the grill.
- 2
Brush cauliflower steaks on both sides with 2 tablespoons of olive oil and season with salt and pepper. Set aside.
Tip: Thick steaks hold together better than smaller florets when grilling.
- 3
Heat a large skillet over medium heat and add 2 tablespoons of olive oil. Toast the panko breadcrumbs and sliced garlic together, stirring constantly for 2-3 minutes until golden and fragrant. Transfer to a small bowl and set aside.
Tip: Watch carefully to prevent burning; the residual heat will continue cooking the garlic.
- 4
Preheat your grill to medium-high heat (about 200°C). Lightly oil the grill grates with a paper towel dipped in oil.
Tip: Clean grates prevent sticking and create better char marks.
- 5
Place cauliflower steaks on the grill and cook for 5-6 minutes per side until tender with charred edges, brushing with reserved oil halfway through cooking. Transfer to a serving platter.
Tip: Let each side develop a golden crust before flipping for maximum flavor.
- 6
Grill mackerel fillets skin-side down for 4-5 minutes without moving them, then carefully flip and cook for 2-3 minutes until the flesh is opaque and flakes easily. The skin should be crispy and smoky.
Tip: Avoid pressing down on the fish; this breaks the delicate flesh and releases juices.
- 7
While fish cooks, whisk together the remaining 2 tablespoons of olive oil, lemon juice, lemon zest, fresh thyme, and red wine vinegar in a small bowl. Season with a pinch of salt and pepper.
Tip: Making the dressing while cooking saves time and keeps everything warm.
- 8
Arrange grilled mackerel fillets and cauliflower steaks on serving plates. Drizzle the lemon-herb oil over both components, then top with the crispy garlic and panko mixture. Scatter fresh parsley over everything and serve immediately.
Tip: Serve hot while the grill marks are still visible and the fish skin is crispy.
