Step-by-Step Instructions
Step 1: Preheat the oven and set up for parboiling
Preheat your oven to 425°F (220°C). Set a rack in the middle of the oven.
Fill a medium pot about two-thirds full with water and stir in 1 tbsp kosher salt. Bring to a boil over high heat.
Step 2: Parboil the potatoes for fluffy centers
Add the halved potatoes to the boiling water and cook for 8 minutes. You’re looking for potatoes that are just starting to turn tender on the outside, but still firm enough to hold their shape.
Drain well and let the potatoes sit in the colander for 2 minutes so excess steam can evaporate (this helps them crisp).
Step 3: Roast the potatoes until crisp and golden
On a rimmed baking sheet, toss the drained potatoes with 2 tbsp extra-virgin olive oil, 3/4 tsp kosher salt, and 1/2 tsp smoked paprika (if using). Spread into a single layer with cut sides mostly down.
Roast at 425°F (220°C) for 25–30 minutes, flipping once halfway through, until deeply golden with crisp edges and tender centers.
If you like, finish the hot potatoes with 2 tbsp chopped parsley and/or 1 tbsp butter melted over the top.
Step 4: Prep the sardines (dry fish = better char)
While the potatoes roast, check the sardines for any stray scales and quickly rinse only if needed. Pat them very dry with paper towels inside and out.
Dry fish is the secret to great grilling: it helps prevent sticking and encourages quick browning.
Step 5: Preheat the grill to high and oil the grates
Preheat a gas grill to high heat (about 500–550°F / 260–288°C), or prepare a charcoal grill for a hot fire (you should be able to hold your hand 5 inches above the grate for only 2–3 seconds).
Clean the grill grates well, then lightly oil them: fold a paper towel, dip it in a little olive oil, and use tongs to rub the grates.
If you have a grill basket, set it out now. Sardines are small and delicate, and a basket makes flipping much easier.
Step 6: Season and grill the sardines quickly
Rub the sardines with 1 tbsp extra-virgin olive oil and season evenly with 1/4 tsp kosher salt.
Place sardines on the hot grill (or in a grill basket). Grill for 2–3 minutes on the first side, without moving them, until the skin releases easily and you see charred spots.
Flip carefully and grill 2–3 minutes more, until the flesh is opaque and flakes easily. If you want to check doneness with a thermometer, aim for 145°F (63°C) in the thickest part, though sardines are often best when just cooked through and still juicy.
Step 7: Finish simply and serve right away
Transfer sardines to a platter. Sprinkle with flaky sea salt while they’re hot so it clings and melts slightly into the skin.
Serve with roasted potatoes, lemon wedges for squeezing, and a final drizzle of extra-virgin olive oil at the table (about 1 tbsp total is perfect).
Tip for easy eating: the skin and bones are typically edible in sardines, but you can also lift the top fillet away and pull the backbone out in one piece if you prefer.
Pro Tips
- Ask your fishmonger to clean them: Request sardines that are gutted with heads on (traditional) or off (easier for some home cooks).
- Dry them well: Moisture is the biggest reason fish sticks. Pat dry thoroughly before oiling.
- Don’t fuss with flipping: Wait until the sardines release easily from the grill. If they’re sticking, give them 30–60 more seconds.
- Use a grill basket for confidence: It makes turning a dozen sardines fast and stress-free.
- Flaky salt at the end matters: It gives little pops of crunch and keeps the seasoning bright instead of dissolving into the fish.
Variations
- Garlic-lemon finish: Warm 1 small grated garlic clove in 1 tbsp olive oil for 30 seconds (don’t brown it), then drizzle over the sardines with lemon.
- Piri-piri touch: Serve with a small dish of piri-piri sauce or a sprinkle of crushed red pepper for heat.
- No grill option (broiler): Broil sardines on a well-oiled sheet pan 4–6 inches from the element for 3–4 minutes per side until charred in spots and flaky.
Storage & Make-Ahead
Sardines are best eaten right off the grill. If you have leftovers, cool promptly and refrigerate in an airtight container for up to 2 days. Reheat gently (a quick warm-through in a skillet over medium-low heat) or enjoy cold, flaked over salad or toast with lemon and olive oil.
You can parboil the potatoes up to 12 hours ahead; drain, cool, and refrigerate. Roast straight from the fridge, adding 3–5 minutes to the oven time.
