Why I Love This Recipe

There’s something so comforting and satisfying about a dish that celebrates the natural flavors of fresh vegetables. This zucchini and yellow squash skillet isn’t just another side—it’s a celebration of summer.

The real magic? It’s the caramelization. When zucchini and yellow squash are sautéed just right, they develop that golden-brown edge that adds depth and flavor to every bite. The combination of fresh garlic, a hint of onion, and simple seasoning takes these humble veggies to another level.

I also love how versatile it is. Serve it as a light lunch, pair it with grilled chicken or salmon, or spoon it over rice or pasta for something more filling. It’s quick, gluten-free, and perfect for weeknights when you just want something easy and nourishing.

And let’s be honest—any dish that gets my family to eat a heaping portion of vegetables without a single complaint? That’s a keeper.

Ingredients for Zucchini and Yellow Squash Skillet Medley

This is one of those recipes that’s greater than the sum of its parts. You’ll be amazed at how a few simple ingredients can come together to create something so flavorful.

Here’s what you’ll need:

• Zucchini – Choose medium-sized zucchini that are firm and vibrant. I like to slice them into half-moons for even cooking and visual appeal.
• Yellow Squash – These pair perfectly with zucchini in both texture and color. Make sure they’re similarly sized so they cook evenly.
• Olive Oil – A good-quality extra virgin olive oil helps bring out the richness of the vegetables.
• Garlic – Fresh garlic adds a sharp, aromatic depth that balances the sweetness of the squash.
• Onion – Thinly sliced onion adds a savory base and complements the squash beautifully. Yellow or white onions work well here.
• Salt and Pepper – Simple seasoning, but absolutely essential.
• Fresh Herbs (Optional but recommended) – I love adding fresh basil, thyme, or parsley for a pop of color and flavor.
• Parmesan Cheese (Optional) – If you’re not keeping it vegan, a sprinkle of grated Parmesan adds a savory, nutty finish.

That’s it. Nothing fancy, nothing complicated—just the essentials to let the vegetables shine.

How to Make This Zucchini and Yellow Squash Skillet Medley

Let’s walk through it step by step. You’ll love how easy and rewarding it is.

Step 1: Prep the Veggies
Wash your zucchini and yellow squash thoroughly. Trim off the ends and slice them into ¼-inch thick rounds or half-moons, depending on your preference. Make sure they’re as uniform as possible to cook evenly. Thinly slice your onion and mince the garlic.

Step 2: Heat the Pan
In a large skillet (I like using cast iron for the best caramelization), heat the olive oil over medium heat until shimmering but not smoking.

Step 3: Sauté the Onion and Garlic
Add the sliced onion to the pan and cook for 3-4 minutes, stirring occasionally until they begin to soften and become translucent. Then stir in the garlic and sauté for another minute. Be careful not to burn the garlic.

Step 4: Add the Squash
Add the zucchini and yellow squash to the skillet in an even layer. Don’t overcrowd the pan—if needed, cook in batches. Let them sit undisturbed for a minute or two so they start to brown, then stir gently and continue to cook for 8–10 minutes.

Step 5: Season and Finish
Season the veggies generously with salt and freshly ground black pepper. Once they’re tender and golden at the edges, turn off the heat. Add fresh herbs and, if using, sprinkle with Parmesan cheese.

Step 6: Serve Hot
Transfer the vegetables to a serving dish and enjoy right away while they’re warm and vibrant.

Substitutions

Don’t have something on hand? No problem—this recipe is super adaptable.

Try these swaps:

• Butter instead of olive oil: For a richer flavor, use unsalted butter or a blend of butter and oil.
• Shallots instead of onions: They add a more delicate, slightly sweet taste.
• Garlic powder instead of fresh garlic: If you’re in a hurry, garlic powder works in a pinch—start with ½ teaspoon.
• Add cherry tomatoes: They bring a juicy pop and pair beautifully with squash.
• Make it spicy: A pinch of red pepper flakes adds a welcome kick.
• Vegan cheese or nutritional yeast: For a dairy-free cheesy flavor, this works wonderfully.

This dish is all about flexibility—adjust it to suit your pantry and your palate.

Best Side Dishes for Zucchini and Yellow Squash Skillet

This vibrant veggie dish pairs well with a variety of mains and sides. Here are three of my go-to pairings:

• Garlic Herb Grilled Chicken: The smoky char of grilled chicken complements the freshness of the squash beautifully.
• Lemon Rice Pilaf: The citrusy brightness of a simple rice pilaf balances the savory squash.
• Roasted Potatoes with Rosemary: For a heartier meal, serve with crispy, golden roasted potatoes on the side.

Whether you’re going light or hearty, these sides round out the meal with ease.

Serving and Presentation Tips

Serving a dish as simple as sautéed zucchini and yellow squash doesn’t mean it has to look plain. In fact, with just a few easy touches, you can make this humble veggie side look restaurant-worthy.

First, use a wide, shallow serving dish so you can spread the squash out and let the golden edges shine. Sprinkle a few extra fresh herbs like parsley or basil over the top just before serving—not only does it add a burst of flavor, but the bright green against the yellow and green squash looks gorgeous.

For a finishing touch, add a light grating of Parmesan or a drizzle of good-quality olive oil. If you’re serving this for guests, a lemon wedge on the side can also be a beautiful and useful garnish that adds fresh acidity to the dish.

If you want to serve it as a main dish, spoon the squash over creamy polenta, quinoa, or couscous for a hearty and wholesome presentation that looks as good as it tastes.

Tips and Tricks to Make This Recipe Better

Even though this recipe is incredibly simple, a few extra tips can take it from good to exceptional.

• Use a hot pan: Don’t rush the preheat. A properly hot skillet helps brown the squash instead of steaming it.
• Don’t overcrowd the pan: This is key. If you pile on too much squash, it will release water and become soggy. Cook in batches if needed.
• Let it sit undisturbed: Allowing the squash to sit for a couple of minutes before stirring helps develop that beautiful caramelized color.
• Use fresh herbs at the end: Adding them too early can make them wilt and lose flavor. Toss them in after cooking for the best result.
• Add a splash of lemon juice or vinegar: A tiny bit of acid at the end balances the richness of the olive oil and adds brightness.

These little techniques can elevate your dish and really let the natural flavors shine.

Common Mistakes to Avoid

Even simple dishes can go wrong if you’re not careful. Here are the most common pitfalls when making this recipe—and how to avoid them.

• Overcooking the squash: This is the biggest mistake. Overcooked squash turns mushy and loses flavor. You want it just tender with a little bite.
• Skipping the salting step: Salt is essential—it draws out moisture and brings out the natural sweetness of the vegetables.
• Using too much oil: A little goes a long way. Too much oil can make the dish greasy.
• Cutting the veggies unevenly: This causes uneven cooking. Aim for uniform slices so everything cooks at the same pace.
• Not using a big enough pan: A small pan leads to overcrowding and steaming instead of sautéing.

Avoiding these mistakes makes all the difference between a watery skillet of squash and one that’s crisp-tender and delicious.

How to Store It

One of the great things about this recipe is that it stores well, making it a great option for meal prep or leftovers.

Let the cooked squash cool completely before storing. Transfer to an airtight container and refrigerate. It’ll keep well for up to 4 days.

To reheat, warm it in a skillet over medium heat with a splash of olive oil, or microwave in 30-second increments until heated through. Avoid overheating or it will become too soft.

While it’s not ideal for freezing due to the high water content of squash, you can freeze it if needed. Place it in a freezer-safe container and use it within 1 month for best results. Keep in mind it may be softer once thawed, but still tasty when mixed into eggs, pasta, or soups.
