What Makes This Recipe a Winner

Using simple ingredients, it's the perfect side dish for busy weeknights and goes with just about any main dish like BBQ chicken.

It doesn't take long to cook on the stove so you aren't heating up your kitchen for very long in the hot summer.

It's a delicious way to use up extra zucchini and squash that's light and nutritious instead of the heaviness found in casseroles or fried options.

Ingredient Info and Substitution Suggestions

If you've ever grown a garden with zucchini and squash, or know someone that does, you're probably familiar with having an overabundance of produce.

If not, they're affordable at most grocery stores or produce stands during summer and pair well with peppers and onions which are also widely available at this time of year.

The garlic and lemon add a ton of fresh flavor and a bit of acidity while finishing with some butter adds just a touch of richness.

Ingredients to make sauteed zucchini, squash, onions, and peppers.

Cooking oil - I use avocado oil; olive oil, vegetable oil, etc. work fine

Butter - You can use salted or unsalted, just adjust the added salt accordingly

Onion - I recommend using yellow or Vidalia onions but use your favorite variety. While fresh tastes best onion powder or dried onion can be substituted.

Bell pepper - Use your favorite. I prefer red or orange for this application for taste and color in the overall dish.

Fresh garlic - Minced or pressed. Fresh adds the most flavor but if you don't have it available you can use storebought minced garlic or garlic powder.

Zucchini - If using an extra large zucchini you may want to deseed it as they can be large and unpalatable. No need to peel them unless you prefer it that way.

Yellow squash - If using extra large squash you may want to deseed them as they can be large and unpalatable. No need to peel them unless you prefer it that way.

Note: I don't recommend using frozen squash or zucchini as I think it would be too watery.

Salt and pepper

Lemon zest and juice - These add extra fresh flavor and acidity. Fresh is tastiest but if not available dried zest and bottled juice can be substituted.

Optional garnish ideas: Fresh chopped herbs such as parsley or chives; chopped green onion; cheese such as parmesan or feta.

Storage and Reheating

This dish is best eaten at the time of preparation as it can get overcooked and watery with reheating.

That said, it can be kept in the refrigerator in a covered container for up to 3 days.

It can then be reheated in the microwave or in a skillet/pot on low until warmed through.

Top tip

If you start to see the zucchini and squash turn a dull, less bright shade of green/yellow I'd remove the veggies from the heat unless you want super soft veggies.

If you want vegetables that still have a bit of a bite they really don't take long to cook and should still be vibrant in color.

FAQ

Do you remove the seeds from zucchini/squash before cooking?

I try to get zucchini/squash in the smaller to medium size where the seeds are also small and don't need to be removed. If using larger squash with unpalatable seeds, or if you don't like the seeds at all, you can certainly remove them before cooking.

Why is my sauteed zucchini bitter?

This is likely no fault of your own as some zucchini is just bitter from its growing conditions, cooked or not. You may want to taste a raw piece before cooking to check. If it is bitter, some say sprinkling with salt and letting it sit for about 15 minutes before rinsing and patting dry can help draw out the bitterness.
