Oh my gosh, you guys, this roasted zucchini recipe? It's like a hug in a bowl. Honestly, it all started a few years ago when my Grandma Rose gave me her old, slightly-stained recipe card. It was so faded, I could barely read the ink! The instructions were a bit… cryptic, let's say. But the smell that wafted from her kitchen whenever she made it? Pure magic. Rosemary, garlic, a hint of lemon… It was the kind of smell that just wrapped you up and said, ‘Everything is going to be okay.’ And to be real, that's exactly what this dish does for me. There have been so many kitchen mishaps along the way once, I even forgot to preheat the oven (oops!), resulting in some seriously sad, undercooked zucchini. But even those imperfect attempts somehow tasted amazing. This recipe is more than just food; it's a connection to simpler times and a reminder that even kitchen chaos can be delicious.

Ingredients
- zucchini: About 2 pounds of zucchini, preferably a mix of yellow and green for color. I swear by the ones from Farmer McGregor's stand they're always so juicy!
- Olive Oil: A good quality extra virgin olive oil is key. I tried using canola oil once, and it just wasn't the same. Plus, the flavor is so much brighter with olive oil.
- Garlic: Oh my goodness, the garlic. I use about 6 cloves, minced. More is more, I say! Fresh is always best, but pre-minced works in a pinch.
- Rosemary: Fresh rosemary is heavenly! About 2 tablespoons, chopped. If you only have dried, use about 1 teaspoon. The aroma is incredible!
- Lemon: The zest and juice of one lemon add brightness. Don't skip this!
- Salt & Pepper: To taste. I always go a little heavier on the salt than most recipes call for.
- parmesan Cheese (optional): For an extra cheesy kick. I grate it fresh, but pre-grated works too.
Instructions
- Prep the Zucchini:
- First, wash and slice your zucchini into half-moons. About half an inch thick is perfect. I always end up with uneven slices, but hey, it’s rustic, right? It's all about the flavor, anyway. Then, toss them with olive oil, minced garlic, chopped rosemary, lemon zest, salt, and pepper. The smell at this point is intoxicating!
- Roast the Zucchini:
- Spread the zucchini in a single layer on a baking sheet. I usually line mine with parchment paper for easy cleanup. Pop it in a preheated oven at 400°F (200°C) for about 20-25 minutes, or until tender and slightly browned. This is where I always get distracted and almost burn them. Don't be like me!
- Add Lemon Juice:
- Once the zucchini is roasted, I squeeze the lemon juice over it. It adds a beautiful zing! Give it a good toss to coat everything evenly. This is also when I usually remember to add a bit more salt.
- Garnish and Serve:
- And finally, garnish with freshly grated Parmesan cheese (if using) and a sprinkle of extra rosemary. Serve it warm. It's amazing as a side dish, but it's also delicious enough to be a main course on its own.
- Taste and Adjust:
- Taste and adjust the seasoning as needed. Sometimes I add a pinch of red pepper flakes for a little kick. Experiment!
- Enjoy!:
- There you have it simple, flavorful, and heartwarming roasted zucchini. Serve immediately and enjoy every delicious bite. It's the kind of dish that makes you feel all warm and fuzzy inside.
You Must Know
- Don't overcrowd the baking sheet! This prevents even roasting.
- Make sure your oven is preheated I know, I know, I've learned this the hard way.
- Taste and adjust seasonings throughout the cooking process. It's all about finding your perfect balance.
Making this recipe always brings back such fond memories of my Grandma Rose. The slightly burnt edges and the perfectly tender zucchini they're all part of the charm. Honestly, it's the little imperfections that make it so special.
Storage Tips
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. I tried microwaving it once, and the sauce separated so don't do that lol. It's best served warm, but it's still tasty cold. Just give it a good toss before serving.

Ingredient Substitutions
You can substitute other summer squash like yellow squash or pattypan squash for the zucchini. I've also experimented with adding different herbs like thyme or oregano. It worked...kinda. Thyme was good, oregano was a bit too strong for my taste. Experiment and see what you like!
