If fall had a signature dish, I’d argue it would be Roasted Hasselback Butternut Squash with Sage Butter. It’s cozy, golden, and so elegant that it looks like you’ve been working in the kitchen all day—even though it’s surprisingly easy. I first made this recipe for Thanksgiving when my kids begged me for “something that looks fancy but isn’t green beans.” (Kids, right?) One bite later, it officially earned a permanent spot on my holiday table.
This dish is roasted to tender perfection, brushed with a silky sage butter glaze, and topped with a little crunch from pecans or pumpkin seeds. Think of it as the autumn cousin of your favorite sweet potato casserole—just less sugary and a whole lot more sophisticated.

Ingredients for Roasted Hasselback Butternut Squash with Sage Butter
When it comes to making Roasted Hasselback Butternut Squash with Sage Butter, the ingredients list is short but mighty. Every item adds its own touch of flavor, texture, or aroma, which is why this dish feels so elevated despite being so easy to pull together. Let’s break it down, because you know I love talking about good food as much as cooking it!
- Butternut Squash (the star of the show)
You’ll want one medium butternut squash, about 2–2.5 pounds. Look for one with a nice long neck—that’s the part that’s easiest to slice into those gorgeous Hasselback cuts. Butternut squash is naturally sweet, and when roasted it turns creamy with caramelized edges. If you love squash as much as I do, you’ll also want to check out my Butternut Squash Minestrone or classic Butternut Squash Soup for more cozy inspiration. - Butter and Olive Oil
Butter alone gives you that rich, nutty flavor, while olive oil prevents burning at high oven temperatures. Together, they create a silky glaze that coats the squash beautifully. If you’d like to explore more buttery dishes, my Texas Roadhouse Butter Chicken Skillet is a must-try for weeknights. - Fresh Sage Leaves
Sage has this earthy, slightly peppery aroma that pairs perfectly with squash. Use about 6 fresh leaves, finely chopped, so the herb gets into every slice of your squash. Sage also brings that signature fall holiday flavor that feels like Thanksgiving on a plate. - Maple Syrup
Just a tablespoon is enough to highlight the natural sweetness of the squash without making it taste like dessert. You’ll notice the balance between sweet and savory, especially when the maple syrup caramelizes in the oven. For another recipe where maple truly shines, check out my Pumpkin Soup Recipe. - Salt and Black Pepper
These humble seasonings may seem basic, but they’re what bring the flavors together. Don’t skimp—salt enhances the sweetness of the squash, while black pepper adds a subtle warmth. - Red Pepper Flakes (Optional)
If you like a tiny bit of heat, add just a pinch. It wakes up the flavor without overpowering the dish. - Chopped Pecans or Pumpkin Seeds
These aren’t just garnish—they add a toasty crunch that makes the tender squash even more satisfying. Plus, they make your presentation look magazine-worthy.
Every ingredient plays its part, and when combined, they create a side dish that feels both comforting and elegant. This is why Roasted Hasselback Butternut Squash with Sage Butter has quickly become one of my go-to recipes for holidays, dinner parties, and even Sunday dinners when I want to treat my family.
Instructions: How to Make Roasted Hasselback Butternut Squash with Sage Butter
Making Roasted Hasselback Butternut Squash with Sage Butter may look fancy, but trust me—it’s all about simple steps and letting your oven do the heavy lifting. Here’s the full process broken down so you can follow along with ease:
Step 1: Preheat Your Oven
Set your oven to 425°F (220°C). A hot oven is key because it helps the squash develop those golden, caramelized edges we all love. Line a large baking sheet with parchment paper—this not only prevents sticking but also makes cleanup a breeze.

Step 2: Prepare the Butternut Squash
Peel the squash completely with a sturdy vegetable peeler. Slice it in half lengthwise and scoop out the seeds with a spoon (you can roast the seeds later as a snack if you’d like). Place the squash halves cut-side down on your cutting board.
Here’s the trick for the “Hasselback” effect: Using a sharp knife, make thin, even slices crosswise about ⅛ inch apart. Don’t slice all the way through—you want the squash to fan out like an accordion while still staying intact.
💡 Pro Tip: Place chopsticks or wooden spoons along both sides of the squash while you cut; this acts like a guardrail and keeps you from accidentally slicing all the way through.
Step 3: Make the Sage Butter
In a small saucepan, melt 3 tablespoons of unsalted butter with 1 tablespoon of olive oil. Stir in the finely chopped sage leaves, maple syrup, salt, black pepper, and (if you like a little heat) a pinch of red pepper flakes.
This sage butter mixture is the heart of the recipe—it soaks into the cuts of the squash, infusing every slice with earthy, savory, and slightly sweet notes.

Step 4: Roast the Squash (Round One)
Place your Hasselback squash halves cut-side down on the prepared baking sheet. Brush generously with the sage butter mixture, making sure it seeps into the slices as much as possible.
Slide the pan into the oven and roast for 25 minutes. During this stage, the squash begins to soften and the butter starts to work its way into those beautiful cuts.
Step 5: Baste and Roast Again
After 25 minutes, carefully remove the pan from the oven. Baste the squash with more of the sage butter (if the butter has solidified, just warm it gently again). This second round of basting is what gives the dish its gorgeous, glistening finish.
Return the squash to the oven and roast for another 20–25 minutes, until the edges are deeply golden and the squash is tender all the way through. You’ll know it’s ready when a fork slips in easily without resistance.
Step 6: Garnish and Serve
Once done, transfer the squash to a serving platter. Sprinkle with chopped pecans or pumpkin seeds for a nutty crunch and a touch of visual flair. Serve warm and watch your guests swoon!

Tips and Tricks for Perfect Roasted Hasselback Butternut Squash with Sage Butter
- Microwave Hack: Pop your squash in the microwave for 3 minutes before slicing—it softens the flesh and makes cutting easier.
- Don’t Skip the Basting: Brushing with butter halfway ensures rich flavor in every crevice.
- Make Ahead: Roast up to a day in advance and reheat at 350°F before serving.
- Variations: Swap maple syrup for honey, or try walnuts instead of pecans.
Storage for Roasted Hasselback Butternut Squash with Sage Butter
- Refrigerator: Store leftovers in an airtight container for up to 3 days.
- Freezer: Not recommended—the texture can get mushy.
- Reheat: Warm in a 350°F oven for 10–12 minutes to bring back the crisp edges.
