📖Why My Recipe Works
- Flavor and Texture- Unlike other recipes, this butternut squash dish is not sweet or mushy. I did not add brown sugar, but instead I used a tangy chimichurri sauce, and it's grilled until cooked through but still has a crisp, firm texture.
- Perfect for Early Fall- It's a great side dish option for when it's still warm enough to grill outside, but you're already craving Fall veggies.
🧾Ingredient Notes
- Butternut Squash- Choose a butternut squash that's smooth, firm, heavy for its size, and without any soft spots or blemishes.
- Avocado Oil- You can also use grapeseed oil or canola oil, basically anything that can stand up to a high heat.
- Chimichurri- To make my homemade sauce, you'll need fresh parsley, fresh oregano, red wine vinegar, garlic, olive oil, crushed red pepper, salt, and pepper. Try my creamy chimichurri if you want a milder version.
💭 More Sauce Ideas
The flavors of my homemade chimichurri complement the grilled butternut squash, but you can use other sauces, too. For a different flavor combination, try pairing the grilled squash with tomato butter, garlic butter sauce, or creamy yogurt dill sauce.
⏲️How to Make Grilled Butternut Squash
How to Cut Butternut Squash
- Peel the Squash- Cut off the ends of the squash, then use a sharp vegetable peeler to peel the outer skin until you reach the orange flesh underneath. If the squash is too hard to peel, you can microwave it for a minute or two to soften the skin slightly.
- Slice It into Rounds- Then, cut the squash into ⅓-inch thick rounds. Use a spoon to scoop out the seeds and stringy pulp from each half. Discard or save the seeds for roasting.
I prefer not to cut the squash in half lengthwise. I find it easier to grill with less chance that it falls between the grates.
Season and Oil
Brush the squash slices with avocado oil and season lightly with salt and pepper.
Grill
Oil the clean grates before placing the squash on them. Grill the butternut squash with the grill lid closed to replicate an oven, which helps in even cooking.
Turn halfway to ensure even grilling and to get nice grill marks on both sides.
How to Make Chimichurri Sauce
Use a food processor to combine the ingredients or chop the herbs by hand if you prefer the traditional method. Letting the sauce rest for at least 20 minutes helps the flavors meld together. Taste and adjust before serving!
🥗What to Serve with Grilled Squash
Grilled butternut squash is best served right after grilling while it's still warm. Serve it as a main course with quinoa or basil and lemon rice and a side of house salad or feta green bean salad. It's also delicious when served as a side dish with BBQ grilled chicken, grilled flank steak, garlic butter steak bites, or roast turkey breast.
Expert Tip
Grill the squash until it is tender but still slightly firm. To check for doneness, you should be able to easily insert a fork or skewer into the squash slice. It should be fork-tender but still hold its shape.
