Oven Roasted Zucchini and Squash

How to cook squash and zucchini in the oven roasted is here. A great healthy vegetable side dish that gets tender with a bit of crisp too.

How to Cook Zucchini and Squash Together

We started this when making air fryer zucchini and squash. If you “know me” at all you know that I am obsessed with my hot air machine. Realizing that not everyone loves small countertop appliances I like to share the “old fashioned” methods too. 😉

This is for bite sized fresh produce. We share how to cook frozen vegetables here in case that is all you have on hand. Typically you can find these varieties year round though. We live in a smaller town so I cannot always find vegetables available during the winter time, but these are an always find.

How Long to Bake Zucchini at 425

15-20 minutes is about right, depending on how large your pieces are. You could use all yellow, or green, or half and half. We added some red onions as well but that would be optional of course. Brings a bit more texture and flavor to the dish so I think it is a nice addition to the sheet pan vegetables.

Ingredients

• 2 zucchini sliced into dials or half moons
• Yellow squash sliced into dials or half moons
• A red onion diced, optional
• Olive oil will keep the outside nice and moist
• I like to mince some of my roasted air fryer garlic
• Italian seasoning we like
• 1 pinch salt and pepper to taste

Variations and Substitutions

Seasonings are up to you but I have a few suggestions here. A light choice would just be a light sprinkle of salt and pepper but I like more than that. If you wanted a bit of heat add red pepper flakes or some chili powder

If you wanted to add something else it would need to cook at the same rate. A suggestion might be halved portobello mushrooms. Things like roasted brussel sprouts and cauliflower are much firmer so you’d want a separate baking sheet with those but could be cooked at the same time (but for longer).

You could slice in half and microwave brussel sprouts until tender first though if you really wanted to include them.

Is Sautéed Squash and Zucchini and Onions as good as baked?

If you wanted to saute this combination in a pan I would suggest using a cast iron pan. It’s okay but will say that roasted in the oven and air fried are by far way better. You won’t get the same great texture as you would in the oven or air fryer. Try them all and see for yourself.

If you did want to add onions like I suggested I would use red but yellow would be my next choice. I think white doesn’t offer the same flavor profile. For an easier cleanup just put a piece of parchment or non stick aluminum foil on the bottom.

How to Cook Zucchini and Squash in the Oven

• Preheat your oven to 425 F. Add diced onions, 1/2 inch or so sliced zucchini and yellow squash to a large bowl and mix.
• Top with oil, finely chopped garlic and Italian seasoning and toss to evenly coat well.
• Spread vegetables onto a baking sheet in a single layer.
• How Long to Roast Zucchini is about 10 minutes. Flip vegetables over with a spatula and return to the oven for 10 minutes more, or until they are as tender as you’d like.

Taste and see if you want a bit more seasoning at this time. I don’t like to be heavy handed at first because you can’t take back salt. I also like actually tasting the flavor of the vegetables y’all. Know what I mean?

Can you bake frozen squash and zucchini in oven?

I would highly suggest using fresh as roasting frozen vegetables doesn’t have as great of a texture. You can do it though with the directions linked above. In that case you want to preheat first and add on to sheet pan without defrosting for best results.

Can you Roast Squash and Zucchini in Air Fryer?

This is just as good if you do have a hot air machine at home. If not I wanted to offer this other method, our #2 go to. I have a link to zucchini and squash air fried above but it is quite simple. Really just like our air fryer vegetables which is the same except with mushrooms too!
