How to Select Good Haddock for Grilling
Whenever you shop for fresh fish, you want to avoid any that show these signs of spoilage:
- an unpleasant smell
- cloudy or sunken eyes
- soft or squishy flesh
- visible damage or blemishes
Fresh haddock, whether whole or a fillet, should have firm flesh with a pearly white color. It will have a slightly fishy smell, but it should remind you of the ocean—not rotten food. If you can buy a whole haddock, make sure the eyes are bright and clear, and the gills should be a nice red.

How to Grill Haddock on the Grill
Making grilled haddock is fast and easy, and this best haddock recipe will walk you through everything you need to do to make delicious haddock on your pellet smoker.
Step 1: Prepare the Haddock
Preparing haddock for this grilled haddock recipe is simple. Simply pat the fish dry. Gently rub or brush a light layer of olive oil on it. Then, season it on both sides with a mixture of salt, pepper, and garlic powder. That’s it!
Step 2: Prepare the Pellet Smoker for the Grilled Haddock
Before we throw the grilled haddock on, we need to prepare your Z Grills pellet smoker.
First, fill your smoker with your favorite Z Grills wood pellets. We generally want to stick with mild wood for fish since it’s easy to develop an overpowering smokey flavor. But this haddock will only cook for 8 minutes on your pellet smoker, so it’s okay to experiment if you want to.
Preheat your pellet smoker to medium heat, about 350°F. Then, oil the grill grates with cooking spray or a paper towel soaked in olive oil.
Instead of cooking the haddock fillets directly on the grill grates, we’ll place them atop a few lemon slices.
So, envision where your fillets will lay. Then, place 2-3 lemon rounds on the grill. Finally, lay the fillets on top of the lemon slices
Step 3: Smoke the Haddock Fillets
Now it’s time to close the lid and let your Z Grills pellet smoker work its magic. When the haddock fillets reach an internal temperature of 145°F, pull them out. This will only take about 8 minutes.
When you make this best haddock recipe, there’s no need to flip or prod the haddock. It’s fast and easy from start to finish.
Step 4: Make the Lemon Garlic Caper Sauce
This final step is optional. Your smoked haddock will taste great without it, but this buttery sauce can bring it to the next level, especially when served with more tame sides like plain rice and veggies.
Simply combine all the sauce ingredients in a saucepan and simmer it for 5 minutes. When it’s ready, you can pour it directly over the haddock fillets.
