Golden Summer Squash with Caramelized Onions

The scent of summer squash sizzling in olive oil always brings me back to my grandmother’s garden. As a child, I would spend hours exploring the rows of vibrant yellow squash, their leaves like giant green umbrellas. Grandma’s simple yet delicious preparation, highlighting the squash’s natural sweetness with caramelized onions, became a family staple—a taste of sunshine on a plate. That memory is the inspiration for this dish, which captures the essence of summer in every bite.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 20 minutes
• Total Time: 35 minutes
• Servings: 4
• Dietary Type: Vegetarian

Ingredients

• 1 1⁄2 – 2 tablespoons extra virgin olive oil, divided
• 2 medium onions, thinly sliced
• 1⁄8 teaspoon salt, possibly more to taste
• 1 1⁄2 lbs summer squash (cut into 1/2-inch thick slices or cubes)
• 1 teaspoon garlic, minced or crushed
• Fresh ground black pepper to taste
• Fresh thyme, minced, for garnish
• Pine nuts, lightly toasted (a handful, optional)
• 3 -4 ounces feta cheese (optional) or 3 -4 ounces goat cheese, crumbled (optional)

Equipment Needed

• Large skillet
• Mixing bowl

Instructions

1. Place a large skillet over medium heat. Let it heat up for about a minute.

2. Add 1 tablespoon of the olive oil to the hot skillet, swirling to coat the pan evenly.

3. Add the thinly sliced onions and salt.

4. Cook, stirring frequently, for about 10 minutes, or until the onions become very tender and lightly golden brown. Don’t rush this process; allowing the onions to caramelize develops their natural sweetness.

5. Transfer the caramelized onions to a bowl and set aside.

6. Return the skillet to the heat and add just a teaspoon or two more of olive oil to slick the pan. You don’t need a lot of oil here; just enough to prevent sticking.

7. Add the summer squash to the skillet in a single layer. Overcrowding the pan will steam the squash instead of browning it.

8. Cook, without stirring, until the squash is deeply golden brown on the bottom, about 1-2 minutes. The goal is to get a nice sear on one side.

9. Toss or stir to flip the squash and continue cooking, undisturbed, for 1-2 minutes longer, or until deeply golden brown on the other side. Again, let the squash develop a good sear.

10. Toss in the garlic, and cook for about 30 seconds, until fragrant. Be careful not to burn the garlic, which can become bitter.

11. Return the caramelized onions to the pan with the squash.

12. Mix well to combine the squash, onions, and garlic.

13. Season to taste with additional salt, if needed, and with a generous amount of freshly ground black pepper. Taste and adjust the seasonings as needed.

14. Serve the golden summer squash hot, warm, or at room temperature, garnished with a light sprinkling of minced fresh thyme, and pine nuts and/or feta cheese or goat cheese, if desired.

Note: You can use any thin-skinned, quick-cooking squash variety for this recipe, such as yellow patty pan, zucchini, or crookneck. Peeling the squash is optional. I typically leave the skin on for added texture and nutrients.

Expert Tips & Tricks

• Achieve perfectly caramelized onions: Low and slow is the key. Don’t crank up the heat to rush the process. Allow the natural sugars in the onions to develop, creating a rich, sweet flavor.

• Get a good sear on the squash: Make sure your pan is hot before adding the squash, and resist the urge to stir it too frequently. Let it sit undisturbed to develop a golden-brown crust.

• Add a touch of brightness: A squeeze of fresh lemon juice or a splash of balsamic vinegar at the end can brighten the flavors and add a touch of acidity.

• Make it ahead: This dish can be made a day in advance. The flavors actually meld together even more as it sits.

Serving & Storage Suggestions

This golden summer squash is incredibly versatile. Serve it as a side dish alongside grilled chicken, fish, or steak. It’s also delicious as part of a vegetarian meal, served over rice or quinoa. The bright colors and flavors make it a perfect addition to any summer barbecue or picnic.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet or microwave until warmed through. This dish is best enjoyed fresh, but it still tastes great the next day. It is not recommended to freeze this dish, as the squash will become mushy upon thawing.

FAQs (Frequently Asked Questions)

Q: Can I use frozen squash for this recipe?
A: While fresh squash is ideal for the best texture and flavor, you can use frozen squash in a pinch. Make sure to thaw it completely and pat it dry before cooking to remove excess moisture.

Q: How do I prevent the squash from getting mushy?
A: Avoid overcrowding the pan, cook the squash over medium-high heat, and don’t overcook it. The squash should be tender-crisp, not mushy.

Q: Can I grill the squash instead of sautéing it?
A: Yes, grilling the squash is a great alternative. Toss the squash with olive oil, salt, and pepper, and grill over medium heat until tender and slightly charred.

Q: What kind of cheese works best with this dish?
A: Feta and goat cheese are classic choices, but you can also use Parmesan, ricotta salata, or even a sprinkle of crumbled blue cheese. Choose a cheese that complements the sweetness of the squash and onions.

A: Absolutely! Bell peppers, zucchini, corn, and tomatoes all pair well with summer squash.
