Begin by cutting the sweet potatoes into chunks and slicing the carrots. Quarter the onions and chop the end off the garlic, leaving the peel on. Season with a pinch of salt, drizzle some olive oil, and pop them in the oven until the veggies are tender. You can cover them with aluminum foil if you want.
Once all of your veggies are soft, transfer them to a blender. And remember to squeeze the garlic out of its peel when adding it to the mix.
To your blender, add a splash of broth, and start blending away. Keep adding broth until you achieve that silky smooth consistency you desire.
Grate a little bit of nutmeg into the mix for that extra dash of flavor. You can add as much as you like according to your personal preference.
And there you have it – a bowl of creamy, dreamy, yummy soup that's a time-saving masterpiece!
