In a small saucepan, melt the butter over low heat. Add the minced garlic, rosemary, thyme, smoked paprika, and a pinch of salt and pepper. Stir and let the mixture simmer for 2-3 minutes until fragrant. Remove from heat and set aside.
In a large mixing bowl, combine the diced butternut squash with olive oil, maple syrup (if using), lemon zest, and half of the herb butter mixture. Toss until the squash is evenly coated.
Spread the squash in a single layer on a baking sheet lined with parchment paper. Roast in the preheated oven for 25-30 minutes, or until the squash is tender and caramelized, stirring halfway through for even cooking.
Once the squash is done roasting, drizzle the remaining herb butter over the cooked squash while it's still hot. Gently toss to incorporate.
Transfer the roasted butternut squash to a serving platter. If desired, sprinkle fresh parsley on top for a pop of color. Serve warm as a side dish or as part of a salad.
Notes
Optional to add maple syrup for sweetness and garnish with fresh parsley.
