Step‑by‑Step Instructions for Charred Summer Squash and Zucchini

Step 1: Prep Vegetables
Begin by washing your zucchini and yellow summer squash thoroughly. Cut them into 1-inch thick chunks to ensure even cooking. For the red onion, slice it into thick wedges while keeping the root end intact. This preparation is key to achieving the perfect char in your Charred Summer Squash and Zucchini.

Step 2: Dry Ingredients
Next, pat the chopped vegetables dry using paper towels. This step is crucial as removing excess moisture helps to prevent steaming, allowing for that mouthwatering char when you cook. Pay special attention to the zucchini; the drier they are, the better the final result will be with a nice sear.

Step 3: Heat Pan
Preheat a cast-iron grill pan over high heat for at least 5 minutes until it starts to shimmer. This high temperature is vital for getting a beautiful char on the vegetables. As the pan heats up, you’ll notice slight ripples in the surface, indicating it’s ready for cooking.

Step 4: Oil and Season
Lightly coat the hot pan with your choice of high-smoke point oil, like avocado or grapeseed, ensuring an even layer. Carefully add the zucchini and squash pieces without overcrowding them, as this will ensure proper browning. Season with garlic powder and smoked paprika to enhance the smoky flavor profile of your Charred Summer Squash and Zucchini.

Step 5: Cook Zucchini and Squash
Allow the zucchini and squash to cook undisturbed for about 4 minutes. You’re looking for a dark sear to form at the bottom. Once the time is up, gently flip the vegetables with tongs and cook for an additional 3 minutes, until they become tender-crisp and beautifully caramelized.

Step 6: Add Onions
After flipping the zucchini and squash, add the thick wedges of red onion to the pan. Cook them alongside the squash for about 4-5 minutes, turning occasionally until they are also well-charred and tender, imparting a sweet flavor that balances perfectly with the other vegetables.

Step 7: Season
Once everything is perfectly charred, remove the pan from heat. Sprinkle the vegetables with kosher salt and cracked black pepper to taste. Drizzle a delightful balsamic glaze over the dish, and toss gently to coat the vegetables. Finally, add fresh parsley for a touch of color and freshness before serving your tasty Charred Summer Squash and Zucchini.

Make Ahead Options

These Charred Summer Squash and Zucchini are perfect for meal prep enthusiasts looking to save time during busy weeknights!

Expert Tips for Charred Summer Squash and Zucchini

Dry Vegetables: Ensure zucchini and squash are patted dry before cooking to avoid steaming. Moisture is the enemy of a good char!
Don’t Overcrowd: Allow enough space in the pan for each piece of vegetable. Cooking in batches prevents steaming and promotes even browning.
Avoid Premature Salting: Resist the urge to salt before cooking. It draws out moisture, leading to soggy vegetables instead of the perfect charred summer squash and zucchini.
Use the Right Oil: High-smoke point oils, like avocado or grapeseed, are key. Steer clear of extra virgin olive oil for high-heat cooking to avoid burning.
Stay Hands Off: Once the vegetables are in the pan, let them sit for a few minutes. Avoid moving them around to achieve that lovely dark sear.
Monitor Heat: Keep an eye on your pan’s heat; too hot can burn, while too low will prevent that lovely char. Aim for that sweet spot where they’re sizzling but not smoking excessively.

Charred Summer Squash and Zucchini Recipe FAQs

What type of zucchini should I use?
Choose small to medium zucchinis for a fresher, firmer texture. They should feel firm to the touch without any dark spots—this indicates ripeness.

How should I store leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. This method helps retain flavor and keeps the vegetables from becoming soggy.

Can I freeze charred summer squash and zucchini?
