The weather turns colder, and the leaves begin to change, it is officially squash season. Hasselback squash is a great option for a plant-based main course, pair it with a simple house salad for a weeknight dinner or let it be the centerpiece of your holiday table.
📖Why This Recipe Works
Butternut squash is notoriously hard to cook. Often it gets made into soups because it is difficult to keep it firm yet soft enough to eat. That is where the hasselback cooking technique comes in.
The squash stays whole at the bottom, but the top is cut into thin slices. This allows the flavor to permeate the entire squash while ensuring it evenly cooks. It also makes for a lovely display.
This recipe is vegetarian and gluten-free. We have also included dairy-free and vegan accommodations so everyone at your Christmas Dinner can enjoy!
Butternut squash is the star of the show. Pick one that is heavy for its size and has no obvious deep cuts or bruises. Any green spots on the skin mean the squash has not fully ripened. The stem should be intact and firm.
Butternut squash can weigh anywhere from 1 pound to 5 pounds. I generally use a 2 to 3-pound squash for this recipe but it really doesn't matter. You just may need more or less of the hot honey butter and a slight adjustment to cooking times.
For this recipe you will also need:
Unsalted Butter- If you use salted butter reduce the salt to ¼ teaspoon.
Honey- Raw local honey is always my favorite. But you can also use brown sugar or maple syrup. You can also use fermented garlic honey and skip the fresh garlic.
Crushed Red Pepper- I tried this recipe with jalapeno pepper to start. I felt it was too overpowering. Dried red chili gives just the right heat and texture. Plus, you can reduce it down to ¼ teaspoon in increase it by ½ teaspoon. Much easier to control the spice level.
Rice Vinegar- Anytime I do a pungent mix of sweet and spicy in a recipe, I balance it with acid. I like rice vinegar for its light flavor. Champagne vinegar is a lovely choice. But when I am out, a little apple cider vinegar can be used.
Aromatics- Fresh sage, fresh garlic, and salt.
Toasted Pecans- You can also toast up the squash seeds or use slivered almonds or chopped walnuts.

⏲️How to Make Hasselback Squash
While this is an easy recipe to prepare, prepping the squash is always the most difficult. I recommend a sharp vegetable peeler and bread knife over a Chef's knife for more control.
Before we get started, preheat your oven to 425 F degrees. If you are cooking other items at the same time, you can reduce the heat to 400 F degrees and cook for an extra 5 to 10 minutes.
I highly recommend lining your pan with parchment paper or aluminum foil. Otherwise, be sure to oil the bottom half of the squash to prevent it from sticking to your baking dish.
Step 1- Hot Honey Butter
In a small saucepan combine your honey and unsalted butter. Melt the butter over low heat, stirring to combine. Add the fresh garlic, finely minced, and the crushed red pepper flakes.
Cook for 1 to 2 minutes to soften the garlic and release the oils in the chili flakes. Remove from the heat and add the fresh sage, salt, and vinegar. Set the butter aside and allow it to steep.
Note: When I first tested this recipe I made brown butter before adding the honey. I didn't find that the extra time and work made any significant difference in this recipe.
Step 2- Cut the Squash
Start by peeling the squash with a vegetable peeler. It is important to peel away all the white skin, so that the orange flesh shows through completely. Any white skin leftover on the squash will make be tough when cooked.
Use a large knife to cut the squash in half lengthwise. Use a spoon to scoop out the seeds and stringy flesh in the center.
Lay the interior side of the squash flat on your cutting board. Place two wooden spoons on each side of the squash.
Using a very sharp knife, make even cuts that are roughly ¼ inch wide. The thin slits should stop approximately ¼ inch from the bottom of the squash leaving each half intact.
Repeat with the other half.
Note: I prefer to use a wooden spoon over chopsticks to align my cuts. Chopsticks are tapered resulting in an uneven depth. The curve of the spoon fits the squash perfectly.
Step 3 - Bake
Place the squash halves center side down on your rimmed baking sheet. Brush or spoon over the melted butter mixture, working it in between the slices.
Bake uncovered for 35 to 45 minutes. The size of your squash will greatly impact the cooking time. Rotate the pan halfway through cooking but leave the squash face down.
The squash is ready when the flesh easily pierces with a fork, but it is not yet mushy.
Step 4- Garnish and Serve
Move the roasted butternut squash to your serving platter. Spoon over any juices from the bottom of the pan. Garnish with the toasted chopped pecans and additional fresh sage leaves.
