Healthy Low Carb Zucchini Side Dish Recipe for Cookouts

This is a great recipe for a cookout that takes just a little bit of time. It is a much more interesting alternative to the potato chip bowl. Use that for an appetizer with some melty cheese dip.

Grilling is my favorite way to cook zucchini in the warmer months. It keeps heat out of my kitchen but adds savory flavor to my meals.

A delicious way to cook this veggie is in a little hot oil on the stove when it is cooler. Sauteed zucchini with a little fresh garlic and a sprinkle of Parmesan cheese is always a hit. I also like to finish it with feta cheese.

However, grilled zucchini is a very healthy side dish and fits right into cookout menus.

You won’t use zucchini rounds in this recipe as they can easily fall through the grill grates. You’ll cut the zucchini into long spears which will hold up on the grill.

Your guests will really enjoy this delicious side dish of grilled zucchini topped with smokey vinaigrette.

What is Zucchini?

Wikipedia classifies the zucchini, also called a courgette, as a summer squash. It is a herbaceous plant whose fruit are harvested when their immature seeds and rind are still soft and edible. Although zucchini is often considered a vegetable, it is botanically classified as a fruit.

The zucchini fruit comes in many shades of green. However, the golden zucchini is a deep yellow or orange. At maturity, they can grow to nearly 3 feet in length, but they are normally harvested at about 6–10 inches long which is considered a medium zucchini.

When cooking most treat this low carb vegetable as an accompaniment or side dish with savory flavor, though occasionally it is used in sweeter cooking like zucchini bread or muffins.

Zucchini can be cooked in many healthy ways just like this zucchini recipe which is low carb.

Ingredients for Low Carb Zucchini with Vinaigrette Recipe

This recipe is a great way to cook fresh zucchini. However, yellow squash could be a perfect substitute if you have them on hand.

  • 4 Tbsp red wine vinegar
  • 1 lime
  • 3 tsp agave syrup
  • 1 ½ tsp ground cumin
  • ¼ cup + 1 Tbsp chopped fresh cilantro
  • 1 tsp salt
  • ½ tsp freshly ground black pepper
  • ½ cup + 1 Tbsp good olive oil
  • 4 Fresh zucchini, quartered lengthwise

How to Make this Low Carb Zucchini Recipe

The best way to begin this recipe is to first preheat your grill. While it is preheating you can make the vinaigrette.

This dish is great no matter what kind of grill you use.

Grill Prep

If you are using a charcoal grill here are your preparation steps for the best results.

  • Open the bottom vent completely.
  • Light ½ chimney starter full of charcoal briquettes. When coals are partially covered with ash, pour over the bottom of the grill.
  • Place cooking grate on top and cover. Open lid vent all the way.
  • Let grill heat up for 5 – 10 minutes.

For a gas grill, use the following instructions for preheating.

  • Turn all burners to high.
  • Close lid and heat about 15 minutes until hot.

When the grill is hot, clean and oil the cooking grate. You will use medium heat to medium-high heat depending on your grill to cook the zucchini. If you have more items on your grill, use medium-high heat. Be careful to watch your veggies closely as they can burn quickly.

Vinaigrette for the Low Carb Zucchini Recipe

Ingredients for smoky vinaigrette

Add the following to a mini food processor:

  • Red wine vinegar
  • Juice of ½ lime or about 1 Tbsp + 1 tsp of juice, but you don’t have to use these exact measurements. If you like a tangy vinaigrette, add more lime juice, but do it a little at a time.
  • Agave syrup
  • Ground cumin
  • ¼ cup cilantro
  • ½ tsp salt and ¼ tsp pepper

Process all of the above ingredients until well blended.

Then, with the processor running, stream in ½ cup of good olive oil and continue to blend until the ingredients are emulsified. Set aside the vinaigrette until ready to drizzle over your grilled zucchini.

In a mixing bowl toss the zucchini quarters with 1 Tbsp olive oil and sprinkle with ½ tsp salt and ¼ tsp pepper.

Grill over medium to medium high heat turning occasionally until golden brown with grate marks. About 2-3 minutes per side or 6 minutes total. This will give your zucchini slices a slightly crispy texture.

Remove from heat and cut in half crosswise. This will give you shorter spears of zucchini which is easier for serving.

Immediately drizzle the grilled zucchini with the cumin vinaigrette. Garnish with 1 Tbsp chopped cilantro or fresh parsley.

Serve warm or at room temperature.
