Buttery Skillet Zucchini and Summer Squash

When zucchini and yellow summer squash begin filling garden baskets, this simple skillet recipe is one of the easiest ways to turn them into a warm, comforting side dish. The vegetables slowly cook with sweet yellow onion, fresh garlic, butter, and familiar pantry seasonings until they are tender and lightly browned around the edges.

This is not a crisp, barely cooked squash recipe. It is a soft, savory, homestyle vegetable dish—the kind that tastes right at home beside skillet chicken, pork chops, meatloaf, grilled hamburgers, or a simple summer supper.

It is also a practical way to use an abundance of garden zucchini without requiring a long list of ingredients or a complicated cooking method. Everything comes together in one oversized skillet, making cleanup almost as simple as the recipe itself.

Ingredients You Will Need

Zucchini and yellow summer squash

A combination of green zucchini and yellow squash gives the dish beautiful color, but you can use whichever variety you have available. Medium squash are usually more tender and contain fewer large seeds than oversized squash.

Unsalted butter

Butter adds richness and helps the onion, garlic, and squash develop their warm, savory flavor. Using unsalted butter gives you more control over the final amount of salt.

Yellow onion

Yellow onion becomes soft and slightly sweet as it cooks in the butter. Thin slices or a medium dice will both work well.

Fresh garlic

Fresh minced garlic adds more depth than garlic powder alone. Add it after the onion has softened so it does not burn.

Simple seasonings

Lawry’s Seasoned Salt, onion powder, and garlic powder give the vegetables plenty of flavor without covering up the fresh squash.

How to Make Skillet Zucchini and Summer Squash

Step 1: Prepare the vegetables

Wash the zucchini and yellow squash, then trim away the stem and blossom ends. Cut each squash in half lengthwise and slice it into half-moons about ½ inch thick.

Keeping the slices slightly thick helps them hold their shape while the vegetables slowly cook. Very thin slices may become overly soft before the excess liquid has time to evaporate.

Step 2: Sauté the onion and garlic

Melt the unsalted butter in an oversized skillet over medium-low heat. Add the yellow onion and cook for about 4 to 5 minutes, stirring occasionally, until it begins to soften.

Add the minced garlic and cook for about 30 seconds. Stir it into the onions just until it becomes fragrant.

Slowly sauté the onion in butter before adding the minced garlic.

Step 3: Add and season the squash

Add the sliced zucchini and yellow squash to the skillet. Sprinkle the vegetables evenly with the seasoned salt, onion powder, and garlic powder.

Gently toss everything together until the squash is coated in the melted butter and the seasonings are evenly distributed.

Toss the sliced squash with the buttery onion mixture and seasonings.

Step 4: Cover and slowly cook

Cover the skillet and continue cooking over medium-low heat for 7 to 10 minutes. Stir the vegetables once or twice so they cook evenly.

During this stage, the squash will begin to soften and release its natural moisture. Keep the heat low enough that the butter and garlic do not scorch.

Why cover it? Covering the skillet briefly traps enough steam to begin softening the squash. The lid comes off again in the next step so the excess moisture can evaporate.

Step 5: Cook away the moisture and lightly brown

Remove the lid and continue cooking for another 10 to 15 minutes, stirring occasionally. As the skillet remains uncovered, the liquid released by the vegetables will begin to evaporate.

Once most of the liquid has cooked away, spread the vegetables into an even layer and let them sit undisturbed for 2 to 3 minutes. This gives some of the squash a small amount of golden-brown pan sear.

Gently stir, taste, and add a little more seasoned salt when needed.

Finish the vegetables uncovered so the moisture evaporates and the edges can lightly brown.

Tips for the Best Skillet Squash

Use an oversized skillet

Zucchini and summer squash release quite a bit of water. A wide skillet provides more surface area, helping the moisture evaporate instead of collecting around the vegetables.

Do not overcrowd the pan

The vegetables will reduce in volume as they cook, but they still need enough room for the released liquid to evaporate. If your skillet is small, cook a half batch or divide the vegetables between two pans.

Keep the heat moderate

Medium-low heat gives the squash time to become tender while protecting the butter, onions, and garlic from burning.

Remove the lid to finish

Covering the skillet helps soften the squash, but the vegetables should finish cooking uncovered. Leaving the lid on for the entire cooking time can make the finished dish watery.

Let the squash sit before stirring

Once the liquid has evaporated, leave the vegetables undisturbed for a few minutes. Constant stirring prevents the pieces from making enough contact with the skillet to brown.

Can I Use Only Zucchini or Only Yellow Squash?

Yes. Use four medium zucchini, four medium yellow squash, or any combination totaling approximately two pounds. The flavor and color will vary slightly, but the cooking method remains the same.

Optional Additions

The simple seasoning is part of what makes this recipe so versatile. For an occasional variation, try adding one of the following:

• A pinch of freshly ground black pepper
• A small amount of dried oregano
• Fresh thyme leaves
• A pinch of crushed red pepper flakes
• Fresh chopped parsley
• A light sprinkle of grated Parmesan before serving

Fresh herbs and Parmesan are best added near the end of cooking so their flavor does not disappear into the dish.

What to Serve with Zucchini and Summer Squash

This easy vegetable side dish pairs especially well with:

• Homemade Skillet Chicken
• Grilled or baked pork chops
• Meatloaf
• Roasted chicken
• Hamburgers or chicken sandwiches
• Grilled steak
• Pasta dishes
• Rice or buttered noodles
• Cornbread and sliced garden tomatoes

How to Store Leftovers

Allow the vegetables to cool, then transfer them to an airtight container and refrigerate them promptly. For the best quality, enjoy the leftovers within 3 to 4 days.

Reheat the squash in a skillet over medium-low heat so any extra moisture can evaporate. Add a small pat of butter when the skillet seems dry. You can also use the microwave, although the vegetables may be softer.

• 1 teaspoon Lawry’s Seasoned Salt, plus more to taste

7. Cover the skillet and cook over medium-low heat for 7 to 10 minutes. Stir once or twice during cooking.
8. Remove the lid and cook uncovered for another 10 to 15 minutes, stirring occasionally, until the vegetables are tender and most of the liquid has evaporated.

Recipe Notes

• Use a wide skillet to help the vegetables release moisture and brown.
• Keep the squash slices about ½ inch thick so they do not fall apart.
• For firmer vegetables, shorten the covered cooking time.
• For softer homestyle squash, cook a few minutes longer over low heat.
• Taste before adding extra salt because seasoned salt already contains sodium.
