Heat the oven to 425°F. Place the cottage cheese on the counter so it can start to come to room temperature.
Peel and seed the squash (and/or other root veggies) and cut into 1-inch cubes. Transfer to a large Dutch oven. Drizzle with 1 tablespoon of the oil, season with 1 teaspoon of the salt and several grinds pepper, and toss to coat.
Nestle the garlic half into the center of the squash, making sure it touches the bottom of the pot. Scatter the thyme sprigs on top and drizzle with the remaining 1 tablespoon oil. Roast, covered, until the squash is very tender, 45 to 55 minutes.
Remove the pot from the oven; discard thyme sprigs. When cool enough to handle, remove the roasted garlic bulb and carefully squeeze the cloves into the pot.
If using an immersion blender: Add the beans, cottage cheese, maple syrup, nutmeg, and cayenne. Pour in 3 cups of the broth. Blend until smooth, adding more broth as needed to reach your desired consistency.
If using a stand blender: Transfer the squash and the garlic to the blender. Add the beans, cottage cheese, maple syrup, nutmeg, and cayenne. Pour in 3 cups of the broth. Blend until smooth, adding more broth as needed to reach your desired consistency.
Place the Dutch oven over medium-low heat to re-warm the soup. Taste and season with salt and pepper, as needed. Ladle into bowls and garnish with toasted pepitas, fresh thyme leaves, and a drizzle of oil. Serve with crusty bread.
