Step-by-Step Instructions

Step 1: Make the Chimichurri (5 Minutes Before Grilling)

Combine parsley, cilantro, and minced garlic in a medium bowl. Pour in the olive oil and red wine vinegar, then add red pepper flakes. Season with salt and pepper, stir everything together, and let it sit while you prepare the fish. The flavors will bloom and come together beautifully.

Step 2: Prep Your Grill

Get your grill hot, really hot. Aim for high heat (around 450 degrees Fahrenheit if you’re using a gas grill). Oil those grates well right before you place the fish down, this is the secret to preventing sticking and getting beautiful grill marks.

Step 3: Season the Halibut

Pat your halibut steaks completely dry with paper towels. Brush both sides lightly with olive oil, then season generously with sea salt and freshly ground black pepper. Don’t be shy here, the seasoning is essential.

Step 4: Grill the Halibut (4 Minutes Per Side)

Place halibut steaks directly on the oiled grates. Let them sit untouched for 4 minutes, you’ll see gorgeous grill marks forming as it sears. Flip gently once, and grill for another 4 minutes on the other side until the fish is just cooked through and flakes easily with a fork.

Step 5: Rest and Serve

Remove halibut from the grill and let it rest on a warm plate for a minute. This keeps it juicy and allows the heat to distribute evenly.

Step 6: Top with Chimichurri

Spoon that vibrant chimichurri generously over each halibut steak. The warmth of the fish will slightly soften the fresh herbs while keeping them bright and punchy.

Pro Tips for Perfect Halibut

Getting beautiful grill marks comes down to one thing: don’t move the fish. Place it on the grates and leave it alone for that full 4 minutes. The oil on the grates and the heat will do the work for you.

Choose thick halibut steaks or fillets, at least an inch thick. Thin fillets cook too quickly and can dry out. Thick cuts give you a forgiving window where the outside gets beautiful color and the inside stays tender and flaky.

Fast Fact: Halibut is one of the leanest fish you can cook, packed with protein and omega-3s, making it a favorite among health-conscious cooks and pescatarians. One serving gives you nearly 30 grams of protein with minimal calories.

Chimichurri Make-Ahead Hack

Here’s the beautiful part about chimichurri: it tastes even better the next day. Make a double batch and store it in the fridge for up to 3 days. Use it on grilled chicken, roasted vegetables, alongside eggs for breakfast, or simply drizzled over fresh crusty bread.

If you want to prep it even earlier in the day, chop your herbs and garlic, store them separately in the fridge, then mix with the oil and vinegar right before serving. This keeps the herbs fresher and brighter if you’re doing this more than a few hours ahead.

The beauty of this sauce is its versatility. You can add fresh mint if you like, adjust the garlic to your taste, or make it spicier by adding extra red pepper flakes. This is your sauce to tweak and make your own.

Serving Ideas

Serve your halibut alongside grilled lemon slices, fresh summer greens with a light vinaigrette, or simply with crusty bread to soak up that incredible chimichurri. A chilled white wine, maybe a Sauvignon Blanc or Pinot Grigio, pairs beautifully here.

For a complete meal with minimal effort, throw some summer vegetables on the grill at the same time, zucchini, bell peppers, or asparagus all cook in the same timeframe. You’ll have everything done in 15 minutes.

“Cooking is like love. It should be entered into with abandon or not at all.” The same goes for grilling halibut, give it your attention and it’ll reward you every time.

Frequently Asked Questions

Can I use fresh halibut or frozen? Both work beautifully. If using frozen, thaw it overnight in the fridge first. Pat it completely dry before grilling to ensure those grill marks take.

What if I don’t have a grill? Pan-sear your halibut in a hot skillet with olive oil for the same 4 minutes per side. You won’t get grill marks, but the fish will be just as tender and delicious topped with chimichurri.

How do I know when halibut is cooked through? Look for flesh that flakes easily with a fork and has turned from translucent to opaque. An instant-read thermometer should read 145 degrees Fahrenheit. Don’t overcook, just cooked is perfect.

Can I make chimichurri ahead? Absolutely, make it up to 3 days in advance and store it in an airtight container in the fridge. The flavors actually deepen as it sits.
