How to Make Garlic Parmesan Roasted Butternut Squash

  1. Heat the oven and pan

    Set the oven to 425 F and place a large rimmed sheet pan inside to preheat so the squash sears on contact.

  2. Prep the squash

    Peel, seed, and cut the butternut squash into even 1 inch cubes, then pat them dry with a clean towel so they roast instead of steam.

  3. Make the garlicky oil

    In a large bowl mix olive oil, minced garlic, vegetable bouillon, sea salt, black pepper, and dried thyme; if your bouillon is a paste, loosen it with 1 teaspoon warm water so it disperses evenly.

  4. Toss to coat thoroughly

    Add the squash to the bowl and toss until every side glistens, taking a minute to work the garlic onto the cubes so it sticks and does not burn on the pan.

  5. Roast and flip

    Carefully pull the hot pan from the oven, spread the squash in a single layer with space between pieces, roast 15 minutes, then flip with a metal spatula and roast 10 minutes more.

  6. Add Parmesan and finish

    Sprinkle the Parmesan over the squash and roast 5 minutes until the cheese is melted, toasty, and the squash is fork tender with caramelized edges, then season to taste and serve with extra Parmesan if you like.

Substitutions

Parmesan -> Pecorino Romano
Use 1/3 cup finely grated Pecorino for a saltier, punchier bite that crisps faster; it melts into a savory crust and brings a little extra tang, so taste before adding more salt.
Vegetable bouillon -> White miso
Whisk 1 teaspoon white miso with 1 teaspoon warm water and mix into the oil for clean umami and round savoriness; it clings beautifully and deepens flavor without clouding the texture.
Dried thyme -> Smoked paprika
Swap 1/2 teaspoon smoked paprika for gentle smoke and warmth that flatters the sweetness of squash and garlic while keeping the edges crisp and bronzed.

Tips

Preheat the sheet pan
A hot pan jump-starts caramelization so the squash gets golden instead of steaming and going mushy.
Dry equals browned
Moisture is the enemy of crisp edges, so blot the cubes before seasoning to keep them roasting, not simmering.
Garlic that does not burn
Mash the minced garlic with a pinch of salt into a quick paste so it sticks to the squash and does not fall to the pan and scorch.
Add cheese at the end
Parmesan can burn if it rides the whole cook, so wait until the last 5 minutes for perfect melt and toasty bits.
Use the right grate
Finely grate with a Microplane for delicate, even coverage that melts fast, or use a small-hole grater for slightly chewier salty pops.
Flip with a metal spatula
A thin metal spatula can slide under the caramelized bottoms and bring the tasty fond with the cubes when you flip.

FAQ

Why did my squash turn out soft instead of caramelized?
The pan was crowded or not preheated, or the squash was wet; use a large hot sheet pan, leave space between cubes, and dry the squash before oiling.
How do I keep the garlic and cheese from burning?
Toss the garlic into the oil so it adheres, and add the Parmesan only for the last 5 minutes; if your oven runs hot, drop to 400 F for the final minutes.
Can I use pre-cut or frozen squash?
Pre-cut is fine if pieces are uniform; frozen releases moisture, so roast it on the hot pan 10 minutes unseasoned to drive off water, then toss with the oil mixture and finish.
What is the safest way to peel a butternut squash?
Trim the ends, halve the squash crosswise where the neck meets the bulb, stand each piece flat-side down, and use a sharp Y-peeler, keeping fingers tucked.
Can I make it ahead?
Roast fully, cool, and refrigerate in a glass container up to 3 days, then re-crisp on a hot sheet pan at 425 F for 8 to 10 minutes or in a skillet over medium-high heat.

Serving Suggestions

A sprinkle of lemon zest and a handful of chopped parsley right before serving brightens the salty-cheesy richness and makes the squash pop.

Pair this with a simply grilled steak or salmon and a bitter greens salad, or go bold and dust the hot squash with a pinch of red pepper flakes for a little swagger.
