Cod Sheet Pan with Potatoes and Tomatoes

Sheet pan cod is one of the easiest ways to prepare this flaky white fish. Baking cod on a sheet pan also allows you to add some delicious veggies in like crispy potatoes, that can cook along with the fish! Cod has a mild flavor and I personally find it to be a very family-friendly fish. My almost three-year old often requests it! That’s also probably because she’s a sauce fanatic and the creamy dill sauce can make anything taste good.

What do I need to make this cod sheet pan meal?

  • Bite-sized potatoesif you only have larger ones on hand, just be sure to chop them into small pieces so that they’ll be nice and crispy!
  • Cherry tomatoesthese are so good when roasted and about to burst plus so easy to just plop on the pan!

  • Creamy dill saucewhile this meal is pretty yummy on its own, this creamy dill sauce is SO good to dip the cod and potatoes in! You’ll need mayo, white wine vinegar, dried dill, salt, and pepper. Full recipe is below!

Is cod healthy?

Yes, cod is a healthy fish! It is high in protein and low in calories. It doesn’t have as much omega-3 as fatty fish, but it’s a nice alternate protein source that is very easy to prepare. Plus, it doesn’t contain high mercury levels so it’s a great fish to eat if you’re pregnant!

Baked Cod with Crispy Potatoes

How do I cook cod in the oven?

Baked cod couldn’t be any easier to prepare! It’s a very forgiving fish, just don’t overcook it. The ideal cooking temperature for cod is 400 degrees for about 12-14 minutes depending on thickness. You can use a fork to see if the fish flakes or if you’re uncertain about using that method to determine if the fish is cooked, you can use a thermometer to make sure it’s 140-145 degrees. I would recommend removing the fish from the oven to test doneness on the early side to avoid overcooking!

I created this sheet pan cod with crispy potatoes recipe at the end of 2020 but apparently it’s taking me a good 6 months to get the recipe on the blog. I’ve probably made it ten times since. The creamy dill sauce alone is worth it! I often make extra for dipping the potatoes but also for basically dipping anything (vegetables, crackers, a finger) in the days following the recipe! If you’re more of a “fried” fish kind of person, my friend Mary over at Mary’s Whole Life has a delicious “Fish & Chips” cod recipe you can try!

KISS Tip: If you’re not a potato fan, substitute asparagus and the ingredients can all cook at the same time!

KISS Tip #2: If you don’t have chimichurri seasoning for the potatoes, Italian seasoning can work in a pinch!

Sheet Pan Cod with Crispy Potatoes and Creamy Dill Sauce

Total Time45 mins
Servings: 6

Ingredients

  • 1.5 lbs cod (2-3 filets)
  • 1.5 lbs bite-sized potatoes (if you can't find bite size, cut small potatoes into bite size pieces)
  • 1 pint cherry tomatoes, cut in half
  • 2 Tbsp avocado oil
  • 1 Tbsp chimichurri seasoning (if you don’t have this on hand, Italian seasoning is a great alternative)
  • 1/2 tsp salt
  • 1/2 tsp cracked black pepper

Creamy Dill Sauce

  • 1 cup avocado mayo
  • 2 Tbsp white wine vinegar
  • 1 tsp dried dill (omit or choose a different herb if you don’t like dill)
  • 1/4 tsp salt
  • 1/4 tsp cracked black pepper

Instructions

  • Preheat oven to 400F.
  • Wash and dry potatoes. Let dry completely before putting them into a large bowl and coating with avocado oil. Add chimichurri, salt and pepper and mix well.
  • Spread potatoes evenly on an ungreased baking sheet and bake for 20 min.
  • While the potatoes are baking, slice cherry tomatoes in half and place in the same bowl that you used for the potatoes. Give them a good stir to pick up any remaining oil and seasonings.
  • After the potatoes have baked for 20 minutes, remove from oven, spray sheet pan and add tomatoes.
  • Using a wooden spoon or spatula, spread potatoes and tomatoes to sides of pan to allow room for fish. Place cod filets in the middle of sheet pan and cover with approximately half of the creamy dill sauce (a silicone brush works nicely), reserving the other half to dip the potatoes in when eating.
  • Bake for 12-14 minutes or until cod easily flakes with a fork. Enjoy!
