This garlic butter sautéed yellow squash transforms humble summer squash into a mouthwatering side dish that even vegetable skeptics will love. The tender squash pieces are bathed in aromatic herb oil and topped with a crispy panko mixture that adds the perfect textural contrast. Ready in just 10 minutes, it's my go-to recipe when garden-fresh yellow squash is abundant.
I discovered this recipe during a summer when my neighbor's garden produced yellow squash faster than they could harvest it. After experimenting with several preparations, this sautéed version became my signature dish at neighborhood potlucks.
Ingredients
- Yellow squash choose medium-sized squash with smooth bright skin for the sweetest flavor and fewest seeds
- Extra virgin olive oil use a good quality oil since its flavor will shine in the herb oil mixture
- Fresh lemon juice brightens the entire dish and balances the richness of the garlic and oil
- Garlic select firm cloves without any green sprouts for the cleanest flavor
- Fresh herbs parsley adds brightness while optional basil and thyme bring aromatic complexity
- Panko bread crumbs these Japanese-style bread crumbs stay crispier than regular bread crumbs
- Vegan Parmesan contributes savory umami notes without overwhelming the delicate squash
- Red pepper flakes optional for those who enjoy a gentle heat that enhances the other flavors
Step-by-Step Instructions
- Prepare the squash
- Slice yellow squash into uniform quarter-inch rounds to ensure even cooking. For larger squash, cut the rounds into half-moons to maintain consistent bite-sized pieces that cook quickly and evenly.
- Create the herb oil
- Combine fresh lemon juice, olive oil, grated garlic, chopped parsley, salt and pepper in a jar with a tight-fitting lid. Shake vigorously until emulsified. This bright mixture infuses the squash with flavor while keeping it from becoming bland.
- Mix the crispy topping
- Combine panko bread crumbs, vegan Parmesan, fresh parsley, salt, pepper and optional red pepper flakes in a small bowl. This mixture brings essential texture contrast and savory notes that elevate the simple squash to restaurant quality.
- Sauté the squash
- Heat olive oil in a large skillet over medium heat until shimmering but not smoking. Add sliced squash and cook for 7-10 minutes, stirring occasionally to ensure even browning. The perfect texture is tender but still with some bite rather than mushy.
- Finish the dish
- Remove the skillet from heat and immediately toss the hot squash with the prepared herb oil. The warm squash will absorb the flavors beautifully. Top with the panko mixture just before serving to maintain maximum crispness and garnish with additional fresh herbs if desired.

The grated garlic is my secret weapon in this recipe. Rather than mincing, I use a microplane to create a fine garlic paste that distributes evenly throughout the herb oil, infusing every bite with gentle garlic flavor without any harsh bits.
Temperature Matters
The key to perfectly sautéed yellow squash is managing your heat properly. Medium heat gives you the control to develop flavor without quickly turning the squash to mush. If your squash releases too much liquid, increase the heat slightly to evaporate excess moisture. The goal is tender squash with caramelized edges that maintain their shape.
Make It Your Own
This versatile recipe welcomes adaptations based on what you have available. Zucchini works beautifully in place of or alongside yellow squash. For a heartier version, add cherry tomatoes during the last two minutes of cooking or sprinkle with crumbled feta instead of vegan Parmesan. Mint or dill can replace parsley for different flavor profiles, while a drizzle of balsamic glaze adds sophisticated sweetness.
Serving Suggestions
This sautéed squash shines as a versatile side dish that complements almost any protein. I particularly love serving it alongside grilled fish or a simple pasta. For a complete vegetarian meal, pair it with a hearty grain like farro or quinoa and add a protein element such as white beans or a fried egg on top. The contrasting textures and bright flavors make this humble vegetable feel special enough for company.

Recipe FAQs
- → Can I use other types of squash for this dish?
Yes, you can substitute zucchini, pattypan squash, or any summer squash variety. For denser winter squash like butternut or acorn, you'll need to increase the cooking time and possibly add a little water to help them steam and soften.
- → How do I prevent the squash from becoming mushy?
To avoid mushy squash, don't overcook it. Sauté just until the squash is tender but still has a slight bite, about 7-8 minutes. Also, cutting the squash into slightly thicker slices (about ¼-inch) helps maintain its structure.
- → Is there a substitute for the Vegan Parmesan?
You can use regular Parmesan cheese if you're not following a vegan diet. For a dairy-free alternative, nutritional yeast mixed with a pinch of salt will provide a similar savory flavor to the breadcrumb topping.
- → Can I make this dish ahead of time?
This dish is best served immediately after cooking to enjoy the contrast between the tender squash and crispy topping. However, you can prepare the herb oil and breadcrumb mixture up to a day in advance and store in the refrigerator until ready to use.
- → What main dishes pair well with this sautéed squash?
This versatile side dish pairs beautifully with grilled proteins like chicken, fish, or tofu. It also complements pasta dishes, risotto, or can be served alongside other summer vegetables for a vegetable plate. For a light meal, serve it with a grain like quinoa or farro.
- → How can I add more flavor to this dish?
Enhance the flavor by adding fresh herbs like basil, oregano, or dill to the herb oil. You could also include caramelized onions, sun-dried tomatoes, or toasted pine nuts. For a spicier version, increase the amount of red pepper flakes in the breadcrumb topping.
