Squash and Onions is a classic Southern dish that perfectly captures summer flavors. Tender yellow squash and sweet Vidalia onions sautéed in butter and perfectly seasoned make a simple, old-school side dish that can be cooked in just 15 minutes!

This simple dish brings back such wonderful memories of Sunday lunch after church. My Grandmother’s table would be loaded with perfectly cooked dishes using the best seasonal ingredients, and squash was always one of the all-stars on the menu!

What You’ll Need
- Yellow squash, cut into rounds, works excellent. I prefer Zepher squash, but if you can’t find it, see below for some alternative options.
- Vidalia onions that are thinly sliced are best for this dish because they are slightly sweet.
- The rest is just olive oil, kosher salt, cracked black pepper, and butter.
Switch It Up: Flavor Twists to Try
Swap in Zucchini: Mix with yellow squash for a colorful twist.
Add Garlic: Stir in a clove or two of minced garlic for extra flavor. A handful of fresh herbs like basil, thyme, or parsley is a nice touch, too.
Turn Up the Heat: A pinch of red pepper flakes or a splash of hot sauce adds a little kick.
Sprinkle on Cheese: A light dusting of shredded cheddar or grated Parmesan is so good, y’all.
Donya’s Tips For Preventing Soggy Squash
Squash has a lot of moisture, and nobody likes watery food, right? But here’s the trick to avoid soggy squash: After you’ve sliced your squash, pat it extra dry with a paper towel and sprinkle with a pinch of salt to help dry it out before you start cooking it.

How To Make Squash And Onions
- Step One: Heat olive oil in a medium-sized sauté pan. Add onion and cook on medium until soft.
- Step Two: Add the squash, water, salt, and pepper. Stir gently. Continue cooking until the squash is tender.
- Step Three: Gently add butter and toss to coat the squash and onions. Taste and adjust seasonings. This can be served with a sprinkle of Parmesan cheese or fresh herbs.
