Create THE BEST Grilled Zucchini with a delicious, simple marinade and a few tips and tricks to guarantee perfectly crispy zucchini! Serve the zucchini with grilled marinated steak or lemon rosemary chicken for a delicious meal on the grill!
The past few summers, our neighbors have grown an abundance of zucchini and summer squash. They are kind enough to share their surplus with us and after grilling the squash all summer, my husband and I perfected our marinade recipe. A simple combination of spicy brown mustard, A1 sauce and olive oil creates a flavorful zucchini marinade.
The key to getting a nice char on the zucchini? A hot grill! No one wants soggy squash, so be sure to fire up the grill and get it nice and hot before adding the zucchini. This will result in crispy, charred, grilled zucchini every time!
If you have summer squash on hand, in addition to zucchini, feel free to toss it in! This recipe works with either summer yellow squash, zucchini, or a combination of both.
Ingredients
Here I explain the best ingredients for this grilled zucchini recipe, what each one does, and substitution options. For the exact ingredient measurements, see the recipe card at the bottom of this post.
- Zucchini – you can also use yellow summer squash in this recipe, or a combination of both summer squash and zucchini. You’ll want about 2 pounds of squash, which is around 4 medium-size zucchinis.
- Spicy brown mustard – don’t let the name fool you, this recipe is definitely not spicy! But this mustard does add a nice zing to the marinade.
- A1 sauce – the combination of tart, sour, salty and peppery tastes in the sauce add great flavor to the marinade.
- Olive oil
- Sea salt
How to cut zucchini for grilling
The best way to get crispy grilled zucchini is to cut it into thin spears. How to do this will depend on the size and shape of the zucchini.
If you have pretty straight, medium zucchini, start by cutting the zucchini in half lengthwise. Remove the stem and bottom of the zucchini. Slice each half of zucchini lengthwise into 4-6 spears.
If the zucchini is really large, you may want to cut it lengthwise into quarters, then into spears.
Use this same method for cutting yellow summer squash, if you’re also using it in this recipe.
Instructions
- Make the marinade. Add the sliced zucchini spears to a large plastic bag or container with the spicy brown mustard, A1 sauce, and olive oil. Toss until all of the zucchini is coated in the marinade.
- Marinate the zucchini for at least 1 hour, or up to 8 hours.
- Add the zucchini to the grill. Preheat a grill over medium-high heat, between 425-450°F. Spray the grill grates with cooking spray. Add the zucchini to the grill and sprinkle salt over the zucchini.
- Grill the zucchini for 5-6 minutes, flip and grill for an additional 5-6 minutes.
Remove from the grill and serve immediately. Feel free to garnish with a little flaky sea salt. One of my favorite finishing touches for recipes!
What to serve with it
This marinated grilled zucchini is the perfect summer side dish for just about any meal. But since you’re already firing up the grill, might as well throw the rest of the meal on there as well! I like to pair the zucchini with grilled meats and sometimes another grilled vegetable.
Here are a few of the recipes we’ve made to pair with the zucchini over the last few years!
- Beef: Grilled Marinated Tri Tip, Chipotle Lime Carne Asada, Grilled Steak Skewers, Grilled New York Strip Steak with Peppercorn Crust, Marinated Grilled Skirt Steak
- Chicken: Grilled Marinated Chicken Thighs, Grilled Honey Mustard Chicken, Grilled Sazon Chicken Thighs
- Seafood: Grilled Bacon Wrapped Shrimp, Garlic Lime Grilled Shrimp, Chimichurri Grilled Salmon
- Veggies: Cheesy Grilled Potatoes – for when I’m looking to add another side dish to the meal!

Notes
- How to cut the zucchini: If you have pretty straight, medium-size zucchini, start by cutting the zucchini in half lengthwise. Remove the stem and bottom of the zucchini. Slice each half of zucchini into 4-6 spears, depending on the size of the zucchini. If you have really large zucchini, you may want to cut it lengthwise into quarters, then into spears.
- Use this same method for cutting yellow summer squash, if you’re also using it in this recipe.
- Always make sure the grill is hot before adding the zucchini. This will ensure it gets a nice sear and ends up charred and crispy!
- Feel free to grill the zucchini on a piece of foil. You will still get the wonderful grill marks, with easier clean-up!
- Make sure that the zucchini spears are not too thick. If they’re thicker than half an inch, they won’t get crispy.
- Always marinate the zucchini for at least an hour, longer if possible. The longer you marinate the zucchini, the more flavor you’re going to get. But it does take at least an hour to really get the flavor in the zucchini.
- To roast this zucchini recipe instead of grill it, place the marinated zucchini on a wire rack on top of a foil-lined baking sheet. This will give you the most similar taste and texture to the grilled zucchini. Preheat the oven to 400°F and roast the zucchini for 8-10 minutes. Remove from the oven, flip the zucchini, return to the oven and continue cooking for an additional 8-10 minutes.
- This recipe is gluten free. While A1 sauce is not labeled gluten-free, it does not contain any ingredients with gluten.
