I love cooking simple vegetable recipes during the week like zucchini, asparagus, sautéed broccoli, and glazed carrots because they only take 15-20 minutes to make, they can be paired with just about any protein, and when cooked correctly they're absolutely delicious!
Simple Ingredients
You’ve got to love recipes that use just a few simple ingredients. Only 5 ingredients (plus salt and pepper) is all you need:
- Zucchini and Yellow Squash: I like using a combination of both zucchini and yellow squash. Both are in season during the spring and summer months and they make a colorful final dish!
- Yellow Onion: A little bit of onion goes a long way in this recipe. The onion gets sautéed with butter and oil, then mixed in with the squash and adds so much flavor!
- Butter & Extra Virgin Olive Oil: A combination of both butter and olive oil to sauté the veggies.
- Salt & Pepper: And just a little bit of salt and pepper to bring out the flavor in the squash.

How To Cook Yellow Squash and Zucchini

Step One: Add the sliced squash and onions to a large skillet with butter and olive oil over medium heat. Season with salt and black pepper.

Step Two: Cook the squash on one side undisturbed until it starts to get golden brown. Then give the squash a stir and sauté for several minutes stirring occasionally. Season with a little more salt and pepper. Before you know it, your perfectly cooked squash is ready to enjoy!
Key Recipe Tips!
- Use butter and olive oil. I highly recommend the combination of butter and extra virgin olive oil. The butter adds a wonderful flavor to the squash and the olive oil helps keep the butter from burning while the veggies are sautéing.
- Don’t skip the onion! It may not seem like it, but the onion is what really gives this recipe incredible flavor. Definitely recommend adding it to your squash.
- Control your temperature. You want your heat hot enough to give the squash a golden brown color, but not too hot to where the veggies will burn. Keep the temperature on medium heat and lower to medium-low heat when needed.

Equipment
Ingredients
- 1 medium zucchini
- 1 medium yellow squash
- ½ yellow onion
- 1 Tablespoon butter
- 1 Tablespoon extra virgin olive oil
- ½ teaspoon fine sea salt, divided
- ½ teaspoon freshly cracked black pepper, divided
Instructions
- Wash the zucchini and yellow squash thoroughly. Slice the squash into ¼ inch rounds or half moons. Cut the onion into thin slices.
- In a large 12-inch skillet, heat the butter and the olive oil over medium heat. Add the zucchini, yellow squash, and the onion to the skillet. Toss the veggies with the butter and oil then season with half of the salt and black pepper.
- Now let the squash cook without stirring for 2 minutes on one side so the squash can get a golden brown color. Then gently stir the squash and cook on the opposite side for 3-4 minutes, stirring occasionally, until the squash is tender to your liking. Season with the rest of the salt and black pepper. Enjoy!

I have some cherry tomatoes that I need to use and would like to add them to this recipe. I'm wondering if I should add them first, last, and all together. I like when the tomatoes blister just a little bit.
Marsha McDougal says
That sounds delicious! Although I haven't tested adding tomatoes, I would suggest adding them at the same time as the squash since this recipe cooks pretty fast. You can also add a teaspoon more olive oil if needed. Just make sure to use a large skillet with a big surface area. Let me know how it turns out! 🙂
