Preheat an oven to 375 F. Line a rimmed backing sheet with parchment paper.
Prep the squash. Cut the delicata squash in half lengthwise. Use a spoon to remove the seeds and membrane and discard them. Remove the stem ends and then cut the squash into 1/2-inch thick slices. Toss the sliced squash with 2 tablespoons of the olive oil, the maple syrup, paprika, and salt and pepper.
Roast the squash and shallots. Lay the squash out on one side of the prepared baking sheet. Lay the sliced shallot out on the other side and drizzle with the remaining 1 tablespoon of olive oil. Top with the thyme leaves and sprinkle with salt and pepper. Transfer to the oven and roast for 30-35 minutes.
Make the vinaigrette. In a pint sized mason jar, combine the roasted shallots and thyme, vinegar, olive oil, maple syrup, dijon, and water. Use an immersion blender to blend until smooth and season to taste with salt and lots of black pepper.
Assemble the salad. Lay the greens down in a serving bowl and top with the roasted squash, bacon, candied pecans, and crumbled goat cheese. Top with the fried onion and drizzle with the vinaigrette, or serve the dressing on the side.
