Halibut Steaks

There's something incredibly satisfying about a perfectly baked halibut steak, especially when it's topped with a colorful medley of vegetables. I often turn to this recipe when I want a fuss-free keto meal that still feels special. The fish soaks up all the savory goodness from the mushrooms, zucchini, and tomatoes, making every bite a delight.

Halibut Steaks

Ingredients

  • tablespoon olive oil
  • small onion, halved and thinly sliced
  • /2 bell pepper, sliced thinly
  • ounces sliced fresh mushrooms
  • clove chopped fresh garlic
  • medium zucchini, julienned
  • (6 ounce) halibut steaks
  • /2 teaspoon dried basil
  • /2 teaspoon salt, or to taste
  • /2 teaspoon ground black pepper
  • medium tomato, thinly sliced

Instructions

  1. Step 1

    I start by preheating the oven to 400°F so it's ready when I need it. Then, I heat the olive oil in a skillet over medium heat, adding the onion, bell pepper, mushrooms, garlic, and zucchini. I cover the pan and let everything cook, giving it an occasional stir, until the onions turn translucent—usually about 5 minutes. While that's working, I arrange the halibut steaks in a shallow baking dish. Once the vegetables are tender, I spoon them evenly over the fish. Next, I season everything with basil, salt, and pepper. The dish goes into the oven for 10 minutes. After that, I pull it out and layer the sliced tomato on top, then return it to bake for another 10 minutes. You'll know it's done when the fish flakes easily with a fork. Let it rest a moment before serving so the juices settle.

Chef's Tip

I always season the halibut with a bit of salt and pepper before placing it in the dish—it layers the flavor better. For an extra zesty touch, squeeze fresh lemon over the finished dish.

Storage Tips

Store any leftover halibut in an airtight container in the fridge for up to three days. I find it's best reheated in the oven at 350°F for about 10 minutes to keep the fish moist, but a quick microwave works too.

Variation Tips

For a change of pace, use salmon or cod instead of halibut—they both work beautifully with the vegetable topping. To make it a more filling meal, spoon the steaks and veggies over a generous portion of cauliflower rice or pair with a crisp green salad.
