Roast Halibut with Roast Baby Tomatoes|

Mild flavored and pearly white, there is nothing like fresh Alaskan halibut.  I’m always happy when spring arrives and halibut comes into season. Although it’s pricey right now, I couldn’t resist the beautiful thick filets at the fish counter for our Sunday dinner. With a container of organic Sugar Plum tomatoes left from a catered dinner the night before, I had my inspiration.

Roasted Halibut with Roasted Baby Tomatoes

I tossed halved tomatoes with a generous tablespoon of fresh chopped thyme from my garden, a couple cloves of finely minced fresh garlic, olive oil, salt and pepper and roasted them until they shriveled and started to brown a bit at the edges. Roasting tomatoes develops an amazing flavor as their sweetness concentrates. The fresh thyme is a great compliment.

Fast and Healthy Dinner

I like to sear my halibut on the stovetop then finish in a hot oven. The whole process took just 10 minutes in total. I added brocclini as a side dish and we had a fast, tasty and incredibly healthy dinner in about 25 minutes.

Buying Fish

When you buy fresh halibut figure 4-6 ounces per person. That’s not only portion control, but budget control. The filet I purchased was very thick; two inches to be exact.

If not already done, cut the halibut into 4 portions.  If there is any dark purple flesh on the bottom I carefully trim if off with a sharp filet knife. You can ask the person at the fish counter to do this for you.

A Note On Fish and Seasons

In the winter when I can only get thinner local halibut filets, I still make this. Just adjust the cooking time way down. For thin filets it might take just a minute or two in the oven or you might even be able to cook it just on the stove top. Fresh cod filets would work too. Get what looks good in your local area.

How to Cook the Halibut:  Sear and Roast

Season fish with salt, pepper, and granulated garlic. Heat a non-stick pan over medium heat and drizzle in a little olive oil. When the oil starts to shimmer and liquefy (not smoke), place the halibut filets in the pan presentation side (or top side) down. The fish should sizzle when it hits the hot pan. Allow the halibut to sear for three minutes, until it has a golden crust when you peak underneath. Carefully turn the fish over and sear for one minute longer.

Place halibut on a parchment or foil lined rimmed baking sheet and roast at 425 degrees for approximately 6 minutes. That’s it. Your timing will depend on the thickness of the filets. If they are thinner they will roast more quickly. Your halibut should still be moist and barely translucent in the center, not dry and flaky. Don’t over cook it. If your are not sure, use a digital thermometer. The fish should reach 145°F in the center.

To Finish the Dish

Warm up some dinner plates; place your roast halibut on the plate and spoon on the roast tomatoes. The broccolini takes just three minutes in boiling, salted water. To serve, drizzle the halibut, tomatoes and broccolini all with a little finishing olive oil or a squeeze of lemon.

With fresh halibut in season, try this simple method of roasting fish for an easy and healthy dinner.

Roast Halibut with Roast Baby Tomatoes

Easy to prepare, sear your filets on the stove top and finish in a hot oven. Top with Roast Tomatoes (recipe below) or simply a squeeze of lemon and a little olive oil.


  • 4  4-6 ounce fresh halibut filets, preferably thick filets from Alaska
  • Salt and pepper, to taste ( I like Szechuan Pepper Salt from Penzeys)
  • 2 teaspoons olive oil
  • Lemon wedges, optional


  1.  If cold, allow halibut to get the chill of by allowing it to stand at room temperature for 30-45 minutes.
  2. Cover a quarter or half sheet rimmed backing sheet with parchment or foil and set aside.
  3. Pre-heat the oven to 425 degrees. Place a non-stick skillet or fry pan over medium heat and add oil. Season halibut with salt and pepper. When the oil is shimmering (but not smoking), place the halibut top side down in the pan. Allow a golden crust to form, about 3 minutes. Turn the halibut over and sear 1 minute longer. Remove the halibut to your prepared baking sheet.
  4. Roast in the oven for approximately 6 minutes for 2″ thick filets. If your filets are thinner, roast for a shorter time. When done, halibut will be moist and barely opaque in the center. Remove and serve with a drizzle of good olive oil and a squeeze of fresh lemon.
  5. Note – Another way to test if your fish is done is by using a cake tester tool which is a very thin metal skewer. Place it in the middle of the filet for a few seconds and remove it. Hold it close to your upper lip to feel the heat. Sounds crazy but it works.  If the center is warm, not hot, the fish should be ready.
  6. Roast Baby Tomatoes with Thyme
  8. These bright, herb roasted tomatoes go great with fish and equally as well with chicken. Spoon some over an omelet like salsa or sprinkle into a salad. There are many ways to enjoy them. Next time you have a container of baby tomatoes on the counter and don’t know what to do with them, roast them. Try multi-color baby tomatoes for even more color.
  9. Ingredients
  10. 12-16 ounces organic sweet baby tomatoes such as Sugar Plum or Grapeseed, halved
  11. 1 tablespoons olive oil
  12. 2-3 large garlic cloves, finely minced or squished through a garlic press
  13. 1 generous tablespoon fresh chopped thyme leaves
  14. salt and pepper to taste
  15. Directions
  16. Pre-heat oven to 375 degree, salt and pepper. Spread tomatoes on the baking sheet and roast for 20-25 minutes until shriveled and edges are just starting to turn a bit brown. Timing will depend on your oven. I let mine go about  25 minutes on the convection setting.
  17. Serve warm, or cool and refrigerate.  They will keep a few days in the refrigerator, if they last that longs. Cover a quarter sheet or half sheet rimmed baking sheet with parchment or foil. Toss halved tomatoes with oil, garlic, thyme.
