How To Make Old School Squash and Onions

Putting together Old School Squash and Onions is a breeze—just a few straightforward steps in the skillet bring out the best in these humble vegetables. From slicing to sautéing in a buttery-oil mix, you’ll transform squash and onions into a side that’s tender, lightly browned, and simply irresistible. Follow the detailed instructions below to master each stage, with tips to ensure perfectly cooked veggies every time.

1. Slice the squash into 1/4-inch rounds and thinly slice the onion. Keeping the cuts uniform ensures even cooking and a consistent texture.

2. Heat the butter and olive oil in a large skillet over medium heat. Wait until the butter melts and begins to foam, then swirl the pan so the oil and butter coat the surface.

3. Add the onions and cook until soft and translucent, about 5 minutes. Stir occasionally, allowing each slice to release its natural sweetness without browning too quickly.

4. Stir in the squash, salt, and pepper, then cook until the squash is tender and lightly browned, about 8–10 minutes. Toss gently so each round picks up a bit of caramelization.

5. Sprinkle the chopped parsley over the squash and onions and stir gently, then remove the skillet from the heat. The parsley adds a pop of color and fresh flavor right before serving.

6. Transfer to a serving dish and serve warm. Use a spatula to keep the browned bits from sticking to the skillet, hitting all the best flavors.

Frequently Asked Questions

Here are answers to some common questions about making and enjoying Old School Squash and Onions—because every home cook has a few extra queries.

Q: How long does it take to prepare and cook this recipe?

A: It takes about 10 minutes to prepare by slicing the squash and onions and roughly 13–15 minutes to cook. You’ll spend about 5 minutes softening the onions over medium heat and an additional 8–10 minutes cooking the squash until tender and lightly browned, for a total of around 25 minutes from start to finish.

Q: Can I use other varieties of squash in place of yellow squash?

A: Yes, you can substitute zucchini, crookneck squash, or pattypan squash. Keep in mind that thicker or harder-skinned varieties may require a minute or two of additional cooking time to become tender. Slice them uniformly to ensure even cooking.

Q: What substitutions can I make for the butter and olive oil?

A: You can swap the butter for ghee or use all olive oil if you prefer. Avocado oil or light vegetable oil also work well. Using all butter will give a richer flavor, while all oil will raise the smoke point slightly and keep it lighter.

Q: How can I adjust the seasoning or add flavor variations?

A: To suit your taste, increase or decrease the salt and pepper, add a pinch of red pepper flakes for heat, or stir in a teaspoon of minced garlic along with the onions. You can finish with grated Parmesan or crumbled feta instead of parsley or sprinkle with fresh thyme or basil for a different herb profile.

Q: What is the best way to store and reheat leftovers?

A: Store any leftovers in an airtight container in the refrigerator for up to three days. To reheat, warm them gently in a skillet over medium heat with a small pat of butter or a splash of water to prevent sticking. You can also microwave for 1–2 minutes, stirring halfway through to ensure even heating.
