Ingredients
This is a super simple recipe, calling for only some yellow summer squash, olive oil and salt and pepper.
Variations and topping ideas
- Substitute zucchini for the yellow squash to make grilled zucchini. You can also use zucchini and squash together.
- Use any type of seasoning you like - I love to use this Creole seasoning sometimes for some heat. Garlic powder also gives a nice garlicky flavor to the squash.
- Sprinkle with some feta cheese and/or fresh cherry tomatoes to make a summer squash salad.
- Drizzle with a squeeze of fresh lemon juice (or lime juice).
- Top with fresh herbs like fresh basil, parsley or mint. Red pepper flakes can add a touch of heat to the squash.
Step by step instructions to grill squash

- Start by washing the squash and cutting the ends off. Slice the squash lengthwise in ¼" slices and lay the slices on a baking sheet.

- Drizzle with salt, pepper and olive oil and use your hands to mix it up well.
- Heat the grill to 400°F, place the squash planks on the grill grates, and cook for 2 to 3 minutes per side, until you see char marks on the outside.
Remove and serve warm. Drizzle with fresh lemon and a touch of good quality olive oil if desired. It's also delicious served with a drizzle of Argentinian chimichurri, any fresh vinaigrette or our favorite mint chimichurri.

Expert tips
- Brush the grill with oil before adding the squash to prevent it from sticking.
- The squash should have nice grill marks on both sides when done - make sure your grill is hot enough before putting the squash on.
- For ease, you can also use a grill basket and cut squash into pieces instead of slices.
Frequently asked questions
You do not need to peel yellow squash before cooking it. The skin is very tender and can be eaten.
Pat the squash dry before putting it on the grill. Always make sure you put it on a very hot grill to cook it quickly without letting it get soggy.
Store leftover cooked squash in an airtight container in the fridge for up to 5 days. Reheat leftovers in the microwave in 30 second intervals until warmed through. *Note that squash will become softer when reheated after being leftover.
