Ingredients You’ll Need

Here’s everything you need to make this easy, flavorful walleye on the grill. The foil-packet method keeps the fish tender while simple seasonings let the natural flavor shine.

• 2 (6-ounce) walleye filets
  – Firm and flaky, walleye fish grills beautifully. Look for filets about 1 to 1½ inches thick. Skinless is best for this method.
• 2–3 tablespoons melted butter
  – Unsalted gives you more control, but olive oil or ghee are good substitutes.
• Seasoned salt, to taste
  – Use your favorite blend, or combine kosher salt with paprika and garlic powder.
• Garlic and herb seasoning blend
  – Think parsley, thyme, or dill. Or build your own with dried garlic, onion, and herbs.
• Heavy-duty aluminum foil
  – Holds up better than standard foil and helps seal in moisture when grilling walleye.
• Cooking spray or oil, for the foil
  – Prevents sticking and promotes even cooking.
• Optional: Lemon wedges, for serving
  – Brightens the flavor and balances the richness of the butter.

Grilling walleye doesn’t need to be complicated. Stick to quality ingredients and simple prep, you’ll be amazed at how flavorful this fish can be.

Prefer a different texture? These same filets work beautifully in a foil packet or even an air fryer version for a crispy finish.

How to Grill Walleye (Foil Packet Method)

Grilling walleye in foil is one of the easiest and most reliable ways to get perfectly flaky fish every time. This method locks in moisture, simplifies cleanup, and keeps delicate filets from falling apart on the grates.

Step-by-Step Instructions

1. Preheat the Grill
   Set your gas or charcoal grill to medium-high heat (375–400°F). Let it heat up for 10–15 minutes with the lid closed.
2. Prep the Foil Boats
   • Cut two 12-inch squares of heavy-duty foil.
   • Spray or lightly brush with oil to prevent sticking.
   • Fold up the edges to create shallow “boats” that hold the fish and juices.
3. Prepare the Walleye Filets
   • Check each filet for pin bones and remove if needed.
   • Pat the filets dry with paper towels for better texture.
   • Place one filet in each foil boat.
4. Season Generously
   • Brush melted butter over each filet.
   • Sprinkle with seasoned salt and your garlic-herb blend.
   • Adjust to taste with additional herbs or spices if desired.
5. Seal the Packets
   • Fold the foil over the top and crimp the edges to seal.
   • Leave a little space inside for steam to circulate.
6. Grill the Walleye
   • Place foil packets directly on the preheated grill.
   • Close the lid and cook for 13–15 minutes (no need to flip).
   • The fish is done when it flakes easily with a fork and looks opaque throughout.
7. Rest and Serve
   • Remove packets from the grill and let them rest for 1–2 minutes.
   • Open carefully, watch for steam, and serve with lemon wedges.

Pro Tip: If the edges of the foil start browning too quickly while the center isn’t done, shift the packets to indirect heat for the last few minutes.

This simple grilled walleye recipe is perfect for summer nights, quick dinners, or even camping trips, just bring foil and fire.

Quick Tips for Perfect Grilled Walleye

Grilling walleye on the grill is surprisingly easy, but these tried-and-true tips will help you get perfect results every time.

Preheat Your Grill

Let your grill reach 375–400°F before adding the fish. A steady, even temperature helps steam the fish inside the foil and prevents drying out.

Oil Your Foil

Spray or brush the foil with oil before adding the filets. It’s a simple step that prevents sticking and helps develop better texture on the bottom.

Check Doneness the Smart Way

According to FDA food safety guidelines Walleye is cooked through at an internal temperature of 145°F. You’ll know it’s ready when it flakes easily and turns opaque throughout.

Don’t Open Too Soon

Keep your foil packet closed while grilling. Opening it too early can release steam and slow down the cook time.

Pat Filets Dry First

Blot moisture from the fish before seasoning—it helps create a better surface for flavor and prevents mushy texture.

Let It Rest

Give your grilled walleye 1–2 minutes to rest before opening the foil. This helps the juices settle back into the fish for maximum tenderness.

Skin-On or Skinless?

Skinless filets are easier for foil grilling. But if your walleye fish still has skin, just grill it skin-side down and peel it off after cooking—it’ll slide off easily.

Want to skip the packet and go straight on the grate? Check our guide on breaded grilled fish for a crispy crust version.

Fast Fact: Grilling walleye in foil eliminates flare-ups, locks in moisture, and makes cleanup a breeze, ideal for weeknight dinners or cabin cookouts.
