Sautéed Yellow Squash Ingredients
There’s nothing complicated about this dish, you just need a few simple ingredients:
- Yellow squash
- Sweet onion
- Unsalted butter
- Garlic powder
- Salt and white pepper

How To Make Sautéed Yellow Squash
- Add ingredients to a 12-inch skillet over medium heat.
- Stir and cook the squash and onions until they are softened, about 15-20 minutes.
What is yellow squash?
Yellow squash is a variety of summer squash. They have a creamy white flesh and their seeds are larger than other varieties. They can be found all year round in stores, but their peak season is in the summer months. It is mild tasting with a slight sweetness.
Why sauté with butter?
I sautéed the yellow squash and onions in butter rather than oil as it adds a really nice flavor. If you prefer, or want to make this dish vegan, you can of course use oil instead, you would need about 1 tablespoon.
I prefer to use unsalted butter and then add in the salt to taste. You can use salted butter, but you may want to cut back on the added salt if you do.
Can you use other squashes for this recipe?
I love the flavor and vibrant colors of the yellow squash, but if you can’t get hold of it, you can easily substitute it with either green or yellow zucchini.

Recipe Notes and Tips
- Slice the squash into evenly sized pieces so that they cook evenly.
- Cook the dish on a medium heat. Butter has a low smoking point, so you need to be careful not to burn it.
- Stir the squash frequently while it is cooking.
