Arctic char fillets baked over blistered cherry tomatoes and fresh basil — a Canadian take on a simple, produce-forward baked fish dinner.
Arctic char, a cold-water fish native to Canada's northern lakes and rivers and increasingly farmed sustainably across the country, has a flavor and texture similar to salmon but slightly milder and more delicate, making it well suited to simple preparations that don't overwhelm it. Here, fillets are baked directly over a bed of cherry tomatoes that blister and burst in the oven's heat, releasing their juices to form a light, naturally sweet pan sauce that needs nothing more than fresh basil and a finishing drizzle of olive oil. The technique relies on timing: tomatoes go into the hot oven first to start softening and releasing juice before the fish is added, since char cooks quickly and would overcook if it went in at the same time as raw tomatoes. Once the fish is added, the whole dish finishes together in well under 15 minutes, keeping the char moist and letting the tomato juices reduce just enough to coat the fillets. It's a dish that showcases Canada's growing focus on sustainable, farmed Arctic char as a menu staple, prepared simply enough for a weeknight but polished enough for company.
Serves 4
Preheat oven to 200°C (400°F). Toss cherry tomatoes with 2 tbsp olive oil, garlic, salt and red pepper flakes in a baking dish. Roast for 8 minutes until starting to blister.
Nestle the char fillets among the tomatoes, skin-side down. Drizzle with remaining olive oil and top with lemon slices.
Return to the oven and bake for 10-12 minutes until the fish flakes easily and the tomatoes have burst into a light sauce.
Check char a minute or two early — it cooks faster than salmon and dries out quickly if left too long.
Scatter torn basil over the top and serve straight from the dish, spooning the tomato juices over each fillet.
Buy fillets of even thickness so they finish cooking at the same time; thinner tail pieces cook faster than thicker center cuts.
Don't skip pre-roasting the tomatoes — adding them raw alongside the fish leaves them underdone and the sauce thin and watery.
Tear basil rather than chopping it with a knife to avoid bruising and blackening the leaves.
Substitute salmon or trout if Arctic char isn't available; both share a similar richness.
Add sliced fennel to the tomato bed for a subtle aniseed note.
Swap basil for fresh dill for a more classically Canadian, less Mediterranean-leaning version.
Best eaten fresh. Refrigerate leftovers up to 2 days and eat cold over salad rather than reheating, which tends to overcook the delicate fish further.
Arctic char has been an important traditional food source for Indigenous peoples across Canada's north for thousands of years, and sustainable aquaculture has made it increasingly available in grocery stores nationwide over the past few decades as a lower-impact alternative to farmed salmon. This tomato-and-basil preparation reflects a broader trend in modern Canadian cooking toward simple, produce-forward methods that let high-quality local fish speak for itself.
Arctic char is milder and slightly more delicate than salmon, with a similar pink-orange flesh color but a more subtle, less oily flavor — it works well in dishes where you don't want the fish to overpower other ingredients.
Yes — thaw it fully in the refrigerator overnight and pat it very dry before baking, since excess moisture will dilute the tomato sauce.
Char cooks faster than many people expect due to its lower fat content — start checking for doneness a couple of minutes early and pull it as soon as it flakes easily with a fork.
