This recipe for Baked Halibut with Sour Cream, Parmesan, and Dill Topping has six main ingredients besides salt and pepper, so it barely misses the cut for my category of Five Ingredients or Less. But in spite of that this must 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.

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

This was a delicious and impressive-looking 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!

Can you use another fish 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.

Is this Baked Halibut low in carbs?

It seems worth mentioning that not only is this recipe absolutely delicious, but it also has only about 2 net carbs per serving! And personally I love making a dinner like this that’s absolutely wow and also extra low in carbs.

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

(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 cooked 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.)

This Baked Halibut with Sour Cream, Parmesan, and Dill Topping is a low-carb dinner that's easy but delicious enough to make for guests! And if halibut isn't in the budget you can use other mild white fish for this Baked Halibut recipe.

Ingredients

  • 2 pieces halibut or other mild white fish, thawed if frozen and patted dry with paper towels
  • 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 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.
