I absolutely love making up these Salmon Kabobs, especially during the summer. I pack each skewer with veggies and bite-sized chunks of salmon, and the whole thing comes together in just about 10 minutes on the grill. (I always marinate the salmon first in a mixture of garlic, herbs, and mustard, so you will need to add some time for that.) This is one of my go-to grilling recipes for a quick, flavorful meal when I feel like firing up the grill.

The hardest part about these Salmon Kabobs is waiting for the marinade to do its thing. It’s worth it, though: the Dijon mustard, garlic, and thyme mixture coats and soaks into the salmon. The salmon is then threaded onto skewers along with pieces of zucchini and red onion. After 10 minutes on the grill, the salmon skewers are ready to serve alongside rice and tartar sauce (or tzatziki).

Ingredients to Make Salmon Kabobs

Ingredients for recipe: Dijon mustard, honey, salt and pepper, oil, garlic cloves, fresh thyme, lemon, zucchini red onion, and salmon filets.
  • Dijon mustard: Makes for a punchy salmon skewers marinade.
  • Garlic: Grating it will infuse maximum flavor.
  • Lemon: You’ll use the zest and juice (plus extra wedges for serving).
  • Olive & avocado oil: The first is for taste; the second is for the grill grates.
  • Honey: Sweet balances savory.
  • Thyme: Adds herby, earthy flavor.
  • Salt & pepper: Most savory recipes need this duo.
  • Salmon: Use fresh or frozen.
  • Red onion & zucchini: A quick-cooking pair that does well on the grill.
  • Tartar sauce: Goes great with fish (you could also use tzatziki or Cilantro Yogurt Sauce).
  • Use another veggie: Instead of the red onion and zucchini, try any combination of summer squash, bell peppers, mushrooms, or tomatoes (see my Grilled Veggie Kabobs for inspiration).
  • Switch up the seasoning: Add spices to the marinade, like cumin, coriander, paprika, or curry powder.
  • Swap out the salmon: Try another fish like cod or mahi mahi.

Step 6: Grill until the kabobs are golden brown and lightly charred.

Tips for Making the Best Salmon Kabobs

  1. Soak the skewers. If using wooden skewers, soak them for at least 30 minutes beforehand. This makes sure they don’t burn before the kabobs finish cooking.
  2. Cut the fish and vegetables into even-sized pieces. Doing so will ensure these salmon zucchini kabobs all cook at the same speed.
  3. Allow the grill to preheat. Before adding the salmon and vegetable kabobs, let your grill preheat for 10 to 15 minutes so the fish and veggies cook quickly and evenly. (See more grilling tips here that’ll help your salmon kabobs on grill come out perfectly.)

What to Serve With Salmon Kabobs

Frequently Asked Questions

How long does it keep?

Leftovers can be kept in the fridge for up to three days if stored in an airtight container.

How do you get the vegetables and salmon cook evenly?

I cut the salmon and veggies into uniform sizes, about 2-inch cubes for salmon and 1-inch chunks for the veggies. This way, they cook evenly. Turning the skewers every couple of minutes on the grill also helps everything cook evenly without charring too much on one side.

How long should I marinate the salmon, and can I marinate it too long?

About 30 minutes in the fridge is perfect for this recipe. If you marinate it too long, especially with acidic ingredients like lemon juice, the fish can start to break down and become mushy. I’ve found that 30 minutes lets the flavors get in without changing the texture of the salmon.

These Salmon Kabobs are ideal for grilling all summer long. Zesty from the marinade and lightly charred from the grill, this is a flavorful, fast fish recipe.

    I made your Salmon Kabobs for the July Cooking challenge and they were delicious! The salmon and veggies were very flavorful, and they all cooked evenly. We were concerned that the salmon might need less time than the vegetables, but the salmon was flaky and the vegetables were done but nicely crisp. Thank you!

    1. Yumna J. says:

      Aww, I’m so happy the salmon kabobs and veggies turned out great for you! Thanks, Emiley!

  2. Tracy T says:

    I made these last night and oh my goodness..so good! I made Yumna’s roasted veggie and feta sauce over pasta to go with the kabobs and my family were happy campers. These kabobs are going to be on repeat for me all summer.
    *Quick tip – if your salmon has the skin on simply pour a teeny bit of boiling water over the skin of the raw salmon and the skin will peel right off*

    1. Yumna J. says:

      Sounds like a delicious pairing, Tracy! So glad your family loved the meal. Great tip for removing salmon skin too, thank you for sharing!!

  8. Jennifer Lockhart says:

    Where do you buy your salmon? Do they remove the skin for you? I live in West Michigan and would love to find a butcher that removes the skin. 🙂

    1. Yumna J. says:

      I buy them mostly from Wild Alaskan Company and the ones photographed are from Whole Foods. The fishmonger there can remove the skin for you!
