Other vegetable options would be broccoli, cauliflower, asparagus, carrots, green beans, brussels sprouts, and snow peas. You just want to be sure that you cook the softer vegetables after the more crisp veggies have had a chance to get a head start.

Main Ingredients
- Mushrooms – this recipe calls for white button mushrooms. They are usually the most common and the most inexpensive mushrooms that you will find. While fairly bland, they are great at soaking up flavor. You could also substitute cremini mushrooms or baby bella mushrooms.
- Bell Pepper – any color of bell pepper will work great. Slice into ½” slices and then cut into approximately 2” pieces.
- Yellow Squash – wash and cut the squash in half lengthwise, then cut into ¼” pieces. Zucchini would be a good substitute.
- Olive Oil – it’s a good idea to add a little olive oil to the butter to cook the veggies because olive oil won’t burn as quickly as butter. Avocado oil is a good substitute.
- Butter – butter adds amazing flavor to sauteed veggies. If you want to use only oil, you can substitute an equal amount.
- Garlic – fresh garlic will always have the best flavor. The next best thing would be jarred minced garlic.
- Salt and Pepper
- Parsley – fresh chopped parsley makes a great garnish. It adds color and fresh flavor. Fresh thyme and chives would also taste good.
Step-by-Step Instructions
- Heat the pan. Prepare the veggies, then heat a medium-sized skillet over medium high heat. Add the oil and butter and melt.
- Saute the veggies. Once the oil and butter are hot, add the mushrooms and cook for about 2 minutes, then add the prepared peppers, squash, and garlic. Cook for about 5 minutes more, stirring occasionally until the mushrooms are golden brown and the garlic is translucent or slightly golden brown.
- Serve. Season with salt and pepper and stir to coat. Garnish with chopped parsley and serve warm. Enjoy!

Tips for Making Sauteed Vegetables
- When cooking a variety of veggies, you may need to cook some first. Start with those that will take longer to cook such as mushrooms or crisp vegetables like broccoli. Add softer vegetables like squash and tomatoes later since their cooking time is much less.
- Cut vegetables into similar sized pieces so that they will cook more evenly.
- Be sure to preheat your pan before using it.
- Saute veggies in a combination of butter and oil for flavor and to prevent burning.
- Avoid stirring too much. Let the veggies sit in the pan to develop a golden-brown crust before flipping.
Frequently Asked Questions
When cooking a variety of veggies, I like to use a combination of butter and olive oil. Butter will give that rich buttery flavor, while adding a little olive oil will help prevent it from burning. If you want, you can substitute avocado oil.
I highly recommend using a cast iron skillet to saute vegetables because it retains heat so well and cooks very evenly. It will cook the veggies faster, helping prevent them from getting soggy. A regular stainless steel pan will also work. Or, a wok is a great choice especially if you are making stir fry veggies.
If at all possible, use fresh vegetables for this side dish. They will have a much better texture once cooked.
Storing and Reheating
- Refrigerator: store leftover veggies in an airtight container in the fridge for up to 4 days.
- To reheat: to reheat, you can either microwave or add them to a pan over medium heat.
