Step‑by‑Step Instructions for Grilled Summer Squash with Balsamic Glaze
Step 1: Prep the Squash
Start by cutting the green zucchini and yellow summer squash into 1-inch thick half moons or chunks, ensuring they are uniform for even cooking. Preheat your grill to medium-high heat, aiming for about 400°F (200°C). The vibrant colors of the squash will set the stage for the delicious grilled summer squash with balsamic glaze to come.
Step 2: Salt & Drain
Toss the cut squash with 1 teaspoon of kosher salt in a large bowl. This important step will draw out excess moisture, preventing your squash from becoming soggy. Place the bowl in a colander over another bowl and let it sit for 15 minutes, allowing the salt to work its magic while you get ready for the next steps.
Step 3: Dry Thoroughly
After draining, pat the salted squash pieces dry with clean kitchen towels. This step is crucial to ensure the squash sears beautifully on the grill. You want them to be as dry as possible for that ideal caramelization—this will enhance the flavor of your grilled summer squash with balsamic glaze.
Step 4: Sear Squash
In a skillet, heat 1 tablespoon of olive oil over medium-high heat. Once shimmering, carefully add the squash in batches, cooking for about 3-4 minutes per side. You’ll know when they’re ready to flip when they develop rich, deep brown grill marks and become tender-crisp. Remove them from the skillet as they finish cooking, keeping them warm.
Step 5: Make Balsamic Glaze
Reduce the heat to medium and add the remaining tablespoon of olive oil and minced garlic to the same skillet. Sauté for about 1 minute, until fragrant and golden. Then pour in the balsamic vinegar, add brown sugar and optional red pepper flakes, bringing it to a gentle simmer. Let it cook for about 2 minutes until slightly thickened, stirring occasionally.
Step 6: Combine & Garnish
Toss the seared squash in the skillet with the balsamic glaze, making sure they are well-coated in the glossy mixture. Remove from heat and transfer the grilled summer squash to a serving platter. Garnish with freshly chopped parsley for a pop of color and a burst of freshness. Serve immediately and enjoy this delightful side!

Expert Tips for Grilled Summer Squash
Salt Smartly: Don’t rush the salt step; allowing the squash to drain properly prevents sogginess, ensuring perfect texture in your grilled summer squash with balsamic glaze.
Pat Dry: After draining the salted squash, make sure to pat them thoroughly dry to achieve that desirable caramelized crust when searing.
Avoid Overcrowding: Cook squash in batches to prevent steaming; overcrowding the skillet can lead to uneven cooking, ruining the crispy exterior.
Watch the Glaze: Keep a close eye on the balsamic glaze while it simmers, as it can quickly go from perfectly thickened to burnt. It should coat the back of a spoon.
Experiment with Heat: Adjust the red pepper flakes to your taste. Just a pinch can elevate the flavor without being overwhelming.
Perfect Pairing: For an exciting flavor boost, consider a drizzle of fresh lemon juice over the finished dish to brighten your grilled summer squash!
How to Store and Freeze Grilled Summer Squash
Fridge: Store leftovers in an airtight container for up to 3-4 days. Ensure the container is well-sealed to preserve freshness and flavor of your grilled summer squash with balsamic glaze.
Freezer: For longer storage, freeze cooked squash in a single layer on a baking sheet before transferring to a freezer bag. Enjoy within 3 months for optimal taste.
Reheating: When ready to enjoy, thaw overnight in the fridge, then reheat gently in a skillet over medium heat or in the microwave until warmed through. Avoid overcooking to retain texture.
Pre-Prep Storage: If preparing ahead, you can salt and drain the squash earlier in the day. Store in an airtight container lined with paper towels to absorb excess moisture before cooking.

Grilled Summer Squash with Balsamic Glaze Recipe FAQs
How do I choose the perfect summer squash?
Absolutely! When selecting summer squash, look for firm, unblemished specimens. For zucchini, choose those that are about 6-8 inches long, with smooth, shiny skin. Yellow summer squash should also be smooth, bright, and free from dark spots or blemishes. Avoid those that feel soft or have wrinkled skin.
How should I store leftovers of grilled summer squash?
Very simple! Store any leftover grilled summer squash in an airtight container in the refrigerator for up to 3-4 days. Make sure the container is sealed well to keep the squash fresh and flavorful.
Can I freeze grilled summer squash with balsamic glaze?
Absolutely! To freeze, first let the cooked squash cool completely. Then, spread it out in a single layer on a baking sheet and freeze until solid. Once frozen, transfer the pieces to a freezer bag. For the best quality, consume within 3 months. When ready to enjoy, thaw in the fridge overnight and reheat gently to maintain texture.
What if my balsamic glaze is too thick or too thin?
If you find your glaze has become too thick, simply whisk in a little water or broth over low heat until it reaches the desired consistency. If it’s too thin, continue to simmer for a minute or two to thicken further. A good glaze should coat the back of a spoon but not be overly sticky.
Is this recipe suitable for pets, and are there allergy considerations?
Great question! This recipe is vegetarian and gluten-free, making it safe for most people with dietary restrictions. However, if you have pets, avoid sharing portions with them due to the garlic and salt, which can be harmful in larger quantities. Always check for ingredient allergies such as honey in the glaze if anyone you’re serving has specific allergies.
How can I prep the squash ahead of time?
Definitely! You can prepare the squash by cutting it into the desired shapes and tossing with salt to draw out moisture well ahead of time. After salting, let them drain in a colander for about 15 minutes. To store, place the drained squash in an airtight container lined with paper towels to absorb any excess moisture. They can be stored in the fridge for several hours before cooking, ensuring a quick and easy prep later!
