25-Minute Garlic Roasted Zucchini and Yellow Squash
Oven-roasted zucchini and yellow squash, finished with fresh garlic so it doesn’t burn, and ready in under half an hour. The high heat gives you browned, slightly crisp edges while the centers stay tender. It’s the side dish I keep coming back to because it works with almost anything.

Why This Side Dish Stays in My Rotation
The garlic goes in after roasting, so it stays sharp and fragrant instead of turning bitter. You get a bright, savory punch right at the end.
The squash itself isn’t watery or limp. It caramelizes in spots, and the pieces keep some bite. A squeeze of lemon right before serving wakes everything up without needing anything fancy.
Ingredients

- 2 medium zucchini, about 12 oz total: any size works, but smaller ones have fewer seeds
- 2 medium yellow squash, about 12 oz total: look for firm, glossy skin
- 2 tbsp olive oil: extra-virgin or light, whatever you have on hand
- 3 cloves garlic, minced: use fresh garlic here; jarred will taste flat
- 1/2 tsp kosher salt: plus more to finish if needed
- 1/4 tsp black pepper: freshly ground if possible
- Lemon wedge for serving: optional, but the acid rounds out the oil
Variations / Substitutions
- Turn up the heat: add 1/4 tsp red pepper flakes with the garlic
- Parmesan finish: shower 2 tbsp grated parmesan over the hot squash right after tossing with the garlic, so it melts a little
- Herb swap: replace the garlic with 1 tbsp chopped fresh basil or chives after roasting
- Make it lemony: double the lemon and stir in 1/2 tsp lemon zest for a brighter finish
For a heartier dinner, these go great next to the crispy-skinned chicken thighs from my Sheet Pan Chicken and Potatoes recipe.
How to Make Garlic Roasted Zucchini and Yellow Squash
Step 1: Slice and Season the Squash

Preheat your oven to 425°F (220°C) and line a rimmed baking sheet with parchment if you like easier cleanup. Slice the 2 zucchini and 2 yellow squash into half-moons about 1/2 inch thick. Toss them on the sheet with the 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp pepper until every piece is coated.
Step 2: Roast Until Tender

Spread the squash in a single layer and roast for 15 to 18 minutes. Halfway through, give the pan a shake or flip the pieces with a spatula so the bottoms don’t burn. You want the edges to look deeply browned and the centers to be fork-tender.
Step 3: Toss with Garlic and Serve

Pull the pan from the oven and immediately scatter the 3 minced garlic cloves over the hot squash. Toss gently while the pan is still warm. The heat will take the raw edge off the garlic without cooking it. Add a squeeze of lemon and transfer to a warm plate. Serve right away while the edges are still crisp.
Tips for Crispy, Not Soggy, Roasted Veggies
- Hot oven is non-negotiable: 425°F creates steam fast so the outside dries enough to brown before the inside overcooks
- Give them space: overloading the pan traps moisture and the squash steams. Use two sheets if you need to
- Pat the squash dry: if the rounds look really wet after cutting, blot them with a clean towel before adding oil
- Wait to salt: if you salt and let them sit before roasting, they’ll weep and get mushy. Toss with oil and salt right before they hit the heat
Roast times for half-moons at 425°F (220°C):
| Thickness | Time |
|---|---|
| 1/2 inch | 15-18 mins |
| 3/4 inch | 18-22 mins |
| Bite-sized cubes | 12-15 mins |
What Goes Well With Roasted Zucchini and Squash
This side practically asks for a protein with a crisp crust. A simple pan-roasted salmon fillet gets a lift from the garlicky vegetables. It’s also great next to a grilled flat iron steak, where the char on the meat and the bright squash keep each other in check. For a light dinner, spoon the roasted veg over a bowl of warm quinoa and add a dollop of yogurt.
Frequently Asked Questions
Why did my zucchini turn out mushy?
The oven was likely too low or the pan was crowded. High heat and space are what give you those browned edges instead of steam-logged pieces.
Can I roast these from frozen?
Don’t. Frozen zucchini and squash release so much water that they’ll never brown, so start with fresh.
Can I make this ahead and reheat it?
Yes. Store leftovers in the fridge and reheat in a hot skillet with a tiny splash of oil for a few minutes. The microwave works, but they’ll soften a lot.
What if I don’t want to use garlic?
Skip it and finish with a handful of fresh herbs like dill or parsley, or a dusting of smoked paprika right out of the oven.
