Here is a recipe that transforms butternut squash into a visually striking side. Halve and roast the squash with a simple seasoning blend. The zig zag cut creates elegant, caramelized edges. This method highlights the squash’s natural sweetness with minimal effort. It’s a versatile dish that pairs well with various mains.
Why This Recipe Works
- The zig zag cut maximizes surface area for better caramelization and crisp edges.
- Roasting at 425°F concentrates the squash’s natural sugars, enhancing sweetness without added sugar.
- Using only olive oil, salt, and pepper keeps the preparation simple and lets the squash flavor shine.
- The high heat ensures the squash cooks through while developing a golden-brown exterior in about 35 minutes.
- This technique requires just one baking sheet, making cleanup straightforward.
Ingredients
- 1 medium butternut squash (about 2-2.5 lbs), peeled, halved lengthwise, and seeds removed
- 2 tablespoons olive oil
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper
- Optional: 1 tablespoon chopped fresh rosemary or thyme
Equipment Needed
- Sharp chef’s knife
- Cutting board
- Vegetable peeler
- Large spoon (for scooping seeds)
- Rimmed baking sheet
- Parchment paper (optional, for easier cleanup)
- Small bowl
- Brush or spoon for oil application
Instructions
Step 1: Prepare the Squash
Start by preparing the butternut squash. Use a vegetable peeler to remove the tough outer skin completely. Place the peeled squash on a stable cutting board. With a sharp chef’s knife, carefully cut the squash in half lengthwise. Use a large spoon to scoop out the seeds and stringy pulp from both halves. Discard the seeds or save them for roasting separately if desired. Pat the squash halves dry with a paper towel to remove excess moisture, which helps with browning. This preparation ensures even cooking and makes the zig zag cut easier to execute. Tip: Choose a squash that feels heavy for its size with a firm, unblemished skin for the best texture and flavor.
Step 2: Create the Zig Zag Pattern
Lay one squash half flat-side down on the cutting board. Position your knife at a 45-degree angle about 1 inch from the top end. Make a diagonal cut about 3/4 inch deep into the squash, but do not cut all the way through; leave about 1/4 inch intact at the bottom. Move the knife about 1 inch down the squash and make another diagonal cut in the opposite direction, again stopping before cutting through. Continue this alternating pattern along the entire length of the squash half. Repeat with the second half. The result should be a series of connected triangular sections that fan out slightly when roasted. This cut increases the surface area for caramelization while creating an attractive presentation.
Step 3: Season the Squash
Preheat your oven to 425°F. Line a rimmed baking sheet with parchment paper if using for easier cleanup. In a small bowl, combine 2 tablespoons of olive oil, 1 teaspoon of kosher salt, and 1/2 teaspoon of freshly ground black pepper. If using fresh herbs like rosemary or thyme, chop them finely and add to the mixture. Stir the seasoning blend well to emulsify slightly. Place the prepared squash halves on the baking sheet. Use a brush or spoon to generously coat all surfaces of the squash with the oil mixture, making sure to get into the cuts. Ensure both the flat sides and the zig zag edges are well-coated. This step seasons the squash evenly and promotes browning.
Step 4: Roast the Squash
Place the baking sheet in the preheated oven on the middle rack. Roast the squash at 425°F for 30-35 minutes. Do not cover or flip the squash during roasting. At the 25-minute mark, check for doneness by inserting a fork into the thickest part; it should slide in easily with little resistance. The edges of the zig zag cuts should be deeply caramelized and golden brown, while the interior flesh becomes tender. The high heat ensures the squash cooks through without becoming mushy. Tip: For extra caramelization, you can brush the squash with a little more oil at the 20-minute mark, but this is optional.
Step 5: Serve Immediately
Remove the baking sheet from the oven using oven mitts. Let the squash rest on the sheet for 5 minutes to allow the juices to redistribute. Transfer the halves to a serving platter using a spatula. The zig zag cuts will have opened slightly, creating an attractive presentation. Serve warm as a side dish. The squash pairs well with roasted chicken, grilled steak, or as part of a vegetarian plate. Tip: For added flavor, drizzle with a teaspoon of balsamic glaze or sprinkle with grated Parmesan cheese before serving, but the simple version is complete as is.
Tips and Tricks
For a deeper flavor, roast the squash at 400°F for 40-45 minutes; this slower roast can enhance caramelization. If your squash is particularly large or thick, extend the roasting time by 5-10 minutes, checking with a fork for tenderness. To make ahead, prepare the squash through Step 3, cover, and refrigerate for up to 24 hours before roasting; add 5 minutes to the cooking time if starting from cold. For easier cutting, microwave the whole squash for 2 minutes before peeling and halving to slightly soften the skin. Use a serrated knife if you find the squash skin difficult to cut through initially. Save the squash seeds: rinse, toss with a little oil and salt, and roast at 300°F for 20-25 minutes for a crunchy snack.
Recipe Variations
- Spiced Version: Add 1 teaspoon ground cumin and 1/2 teaspoon smoked paprika to the oil mixture before brushing on the squash.
- Sweet and Savory: Replace black pepper with 1/4 teaspoon cinnamon and a pinch of nutmeg; drizzle with 1 tablespoon maple syrup after roasting.
- Herb-Infused: Use 2 tablespoons melted butter instead of olive oil and add 2 tablespoons chopped fresh sage or parsley.
- Cheese-Topped: Sprinkle 1/4 cup grated Parmesan or crumbled goat cheese over the squash during the last 10 minutes of roasting.
- Citrus Twist: Add the zest of one orange to the oil mixture and squeeze fresh orange juice over the squash after roasting.
Frequently Asked Questions
Can I use other types of squash for this recipe?
Yes, acorn squash or delicata squash work well. Adjust cooking time: acorn squash may need 5-10 minutes less, while delicata squash cooks in about 25-30 minutes. The zig zag cut technique applies to any winter squash with a firm texture.
How do I store and reheat leftovers?
Store cooled squash in an airtight container in the refrigerator for up to 4 days. Reheat in a 350°F oven for 10-15 minutes until warmed through. Avoid microwaving, as it can make the squash mushy and lose its crispy edges.
Is it necessary to peel the squash?
For butternut squash, yes, the skin is tough and not pleasant to eat when roasted. For varieties like delicata or acorn squash, the skin is edible and can be left on, which simplifies preparation.
Can I make this recipe ahead for a dinner party?
Yes, prepare through Step 3 up to a day in advance. Cover and refrigerate the seasoned squash. Roast just before serving, adding 5-7 minutes to the cooking time since it will be cold from the refrigerator.
What if my zig zag cuts aren’t perfect?
Don’t worry. The goal is to create grooves for caramelization, not perfection. Even irregular cuts will roast nicely. Just ensure cuts are about 3/4 inch deep and spaced about 1 inch apart for best results.
Summary
This recipe uses a zig zag cut and high-heat roasting to create a simple, elegant side dish. It highlights butternut squash’s natural sweetness with minimal ingredients. The technique delivers caramelized edges and tender flesh in about 35 minutes.
