Step‑by‑Step Instructions for Grilled Summer Squash with Balsamic Glaze
Step 1: Prepare Squash
Begin by slicing the green zucchini and yellow summer squash into 1-inch thick half moons or chunks. Ensure the pieces are uniform in size to promote even cooking. Using a sharp knife for smooth cuts, this will make your grilled summer squash more visually appealing and easier to handle on the grill.
Step 2: Salt and Drain
Toss the cut squash with 1 teaspoon of kosher salt in a large bowl. Transfer the salted squash to a colander set over a bowl and let it drain for 15 minutes. This step is crucial as it helps draw out excess moisture, ensuring that the final dish has that desirable tender-crisp texture instead of being soggy.
Step 3: Dry Squash
After the squash has drained, pat the pieces completely dry using clean kitchen towels. Drying is vital for achieving that beautiful sear during grilling, so make sure to remove as much moisture as possible. A dry surface allows your grilled summer squash to caramelize perfectly, enhancing its flavors.
Step 4: Sear Squash
In a skillet, heat 1 tablespoon of olive oil over medium-high heat. Once the oil shimmers, add the squash in a single layer without overcrowding the pan. Allow the squash to cook for 3-4 minutes until browned on one side, then flip and cook for an additional 3 minutes. Look for a caramelized golden color to indicate it’s ready to flip.
Step 5: Make Glaze
Lower the heat and add the remaining tablespoon of olive oil and minced garlic to the skillet. Cook for about 30 seconds until the garlic is fragrant, being careful not to let it brown. Stir in the balsamic vinegar, brown sugar, and optional red pepper flakes, allowing the glaze to simmer for 2 minutes until it thickens slightly.
Step 6: Combine
Pour the balsamic glaze over the seared squash and toss gently to ensure each piece is well-coated. The rich glaze will cling beautifully to the grilled summer squash, enhancing its natural flavors while creating a glossy finish that makes the dish even more inviting.
Step 7: Garnish and Serve
Transfer the glazed grilled summer squash to a serving platter and sprinkle with freshly chopped parsley for a pop of color and freshness. This vibrant dish is best served immediately, allowing your family or guests to enjoy the warm, caramelized flavors right off the grill.

Storage Tips for Grilled Summer Squash with Balsamic Glaze
Fridge: Store any leftover grilled summer squash in an airtight container for up to 3–4 days to maintain flavor and texture.
Freezer: For longer storage, freeze the glazed squash in a single layer on a baking sheet, then transfer to an airtight container or freezer bag for up to 3 months.
Reheating: To reheat, thaw in the fridge overnight, then warm gently in a skillet over low heat, adding a splash of olive oil if needed to revive the glaze.
Serving Suggestions: Revive leftovers by tossing in fresh herbs or drizzling with additional balsamic glaze for added flavor when serving.

Make Ahead Options
These Grilled Summer Squash with Balsamic Glaze are perfect for meal prep enthusiasts! You can slice and salt the zucchini and yellow squash up to 24 hours in advance; just remember to keep them covered in the refrigerator. After salting, let the squash drain for about 15 minutes, and then pat them completely dry to ensure they maintain their texture during grilling. When you’re ready to serve, simply follow the last steps: sear the squash, prepare the glaze by sautéing garlic, and combine them for that delicious finish. This not only saves time on busy nights but guarantees that your dish will remain just as delectable!
Expert Tips for Grilled Summer Squash
• Dry Thoroughly: Ensure the squash is completely dry after salting to prevent steaming and achieve that perfect caramelization.
• Avoid Overcrowding: Cook the squash in a single layer in the skillet; overcrowding can lead to uneven searing, resulting in sogginess instead of a nice brown crust.
• Mind the Glaze: Keep a close watch while reducing the balsamic glaze. It should thicken but avoid cooking it until it becomes overly sticky, which can burn the edges.
• Taste and Adjust: Feel free to tweak the sweetness or spice of the glaze; personal preferences can vary, so taste before serving!
• Explore Variations: Experiment with flavor by adding fresh herbs or citrus zest to your grilled summer squash with balsamic glaze for a refreshing twist.
