PIN the Baked Halibut so you can make it later!

This recipe for Baked Halibut (with Sour Cream, Parmesan, and Dill) has only six main ingredients besides salt and pepper, and this might be about the easiest recipe in the world for Baked Halibut! I splurged on the fish, since my Costco started carrying Halibut again, but see tips for other fish that would be less expensive if halibut isn’t in the budget for you.

And even if you don’t use Halibut, this was a delicious and impressive-looking baked fish dinner that would be perfect to serve to guests, but also easy enough to make for yourself if you’ve had a rough day and just need something quick and tasty. I hope you’ll try it!

What ingredients do you need?

(This is only a list of ingredients; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe with ingredient amounts.)

• halibut or other mild white fish, thawed if frozen
• salt and fresh ground black pepper to taste
• sour cream
• Garlic Powder (affiliate link)
• dried Dill Weed (affiliate link)
• finely ground Parmesan cheese
• sliced green onion

What other fish can you use for the Baked Halibut recipe?

Halibut is definitely a lot more expensive than it was when I created this recipe! So if that just isn’t in the budget for you, you can use the same method to cook other mild white fish like Cod, turbot, haddock, flounder, striped bass, sole, or swordfish. Or use any mild white fish that’s available in your area.

How can you tell when Baked Halibut is fully cooked?

As you can see from the photos, my pieces of halibut were quite thick, so I used an Instant Read Meat Thermometer (affiliate link) to tell when the halibut was done. If you don’t have one of those, cook the pieces of fish until it’s firm, but not hard to the touch.

How low in carbs is the Baked Halibut?

This baked fish recipe is absolutely delicious and it also has only 2 net carbs per serving and 40 grams of protein! And personally I love a dinner like this that’s absolutely a wow and also extra low in carbs.

How to Make Baked Halibut (with Sour Cream, Parmesan, and Dill):

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

1. Any recipe for cooking fish should start with letting the fish come to room temperature. In land-locked Utah I’m using frozen halibut, so I thawed it overnight in the refrigerator.
2. When I was ready to cook the halibut, I used a paper towel to press down on the fish and draw out some of the water, then let it come to room temperature in these little baking dishes. 
3. Preheat oven to 375F/190C.
4. Slice enough green onions to make 3 T sliced green onions, then set aside 1 T for the topping and very finely chop the rest.
5. Mix together the sour cream, garlic powder, dill weed, finely grated Parmesan cheese, and finely chopped green onion. Dill weed (affiliate link) is dried dill leaves, but if you had fresh dill I would definitely use that and just increase the amount a little.
6. When the fish has come to room temperature, season each piece with a little salt and fresh ground black pepper.
7. Then use a rubber scraper to spread a thin coating of the sour cream mixture over the top of each piece of fish. You want the topping to be an even thickness all the way across each piece.
8. Timing will depend on the thickness and type of fish you’re using, but I baked these thick halibut pieces for about 24 minutes to get the temperature to reach 145F, the temperature recommended on the package of frozen halibut. The fish was still moist but perfectly cooked. (My pieces are extra thick; thinner fish will need quite a bit less time.)

Make it a Low-Carb Meal:

Baked Halibut would taste great with Twice-Baked Cauliflower, Stir-Fried Spinach with Garlic and Parsley, or Green Beans with Lemon, Parmesan, and Pine Nuts for a low-carb meal.

Baked Halibut (with Sour Cream, Parmesan and Dill)

Prep Time 10 minutes

Cook Time 24 minutes

Total Time 34 minutes

This Baked Halibut is a low-carb dinner that's easy to make but delicious enough to serve for guests! And if halibut isn't in the budget you can use other mild white fish for this baked fish dinner.

Ingredients

• 2 pieces halibut or other mild white fish, thawed if frozen and patted dry with paper towels (see notes)
• salt and fresh ground black pepper to taste
• 3 T sour cream
• 1/4 tsp. garlic powder
• 1/4 tsp. dill weed (dried dill leaves)
• 2 T finely ground Parmesan cheese
• 3 T sliced green onion

Instructions

1. Thaw frozen halibut overnight in refrigerator, then place in baking dish and blot dry with paper towels.
2. Let the halibut come to room temperature while you prep other ingredients. Preheat oven to 375F/190C.
3. Slice 3 T green onions, then measure 2 T and finely chop them. Reserve the other 1 T sliced onions to garnish the cooked dish.
4. In a small bowl, stir together the sour cream, garlic powder, and dill weed (affiliate link). Stir in the finely grated Parmesan cheese and green onions.
5. When fish has come to room temperature, use a rubber scraper to spread an even coating of this topping over each piece of the fish, using all the topping mixture.
6. Bake fish until the internal temperature reaches 145F/62C, or until fish pieces feel firm but not hard to the touch. (Use a fork to press down to test.) I baked my extra-thick pieces of halibut for 24 minutes, but other types of fish or thinner pieces will cook much more quickly.
7. Serve hot, sprinkled with remaining sliced green onions.
