Step‑by‑Step Instructions for Roasted Garlic Mashed Butternut Squash
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This warm environment will be essential for roasting the butternut squash and garlic to perfection. While the oven heats, prepare your ingredients, ensuring everything is ready for assembly.
Step 2: Prepare the Butternut Squash
Carefully halve the butternut squash lengthwise and scoop out the seeds, revealing its vibrant orange flesh. Place the squash cut-side up on a baking sheet lined with parchment paper, as this will keep the squash from sticking and make cleanup easier.
Step 3: Add the Garlic
Take the whole bulbs of garlic, peel off any loose skins, and place them alongside the squash on the baking sheet. Drizzle everything with about 1 tablespoon of olive oil and season generously with salt and freshly cracked black pepper to enhance the flavors of your roasted garlic mashed butternut squash.
Step 4: Roast the Squash and Garlic
Slide the baking sheet into your preheated oven and roast for 35–40 minutes. Keep an eye out for the squash becoming fork-tender and the garlic turning golden brown, which signals that they are perfectly caramelized and ready to shine in your dish.
Step 5: Scoop Out the Squash
Once the squash has cooled slightly, scoop out the tender flesh into a large mixing bowl. Make sure to include all the delightful roasted garlic you can find! This combination will create the creamy base for your roasted garlic mashed butternut squash.
Step 6: Mix Ingredients
To the bowl with the squash and garlic, add a dash of ground nutmeg, the remaining olive oil, almond milk, and optional butter. Use a potato masher or hand mixer to blend everything until you achieve a smooth and creamy consistency that is irresistible and perfect for a cozy meal.
Step 7: Taste and Adjust Seasoning
Before serving, take a moment to taste your roasted garlic mashed butternut squash. Adjust the seasoning with more salt and pepper if needed, ensuring the flavors are balanced and delightful.
Step 8: Garnish and Serve
Transfer your creamy mash to a serving dish and garnish with freshly chopped parsley or chives for a touch of color and freshness. Serve warm alongside your favorite mains, and bask in the comforting aromas of fall filling your home.
