0 Preheat the oven to 400 degrees(F).
1 Peel the onion and cut into large chunks. Peel the garlic cloves, you can leave them whole. 
2 Put the onions and garlic on a sheet pan. Drizzle with the olive oil and sprinkle with pinch of salt and pepper. Toss to coat. Roast them for 25-30 minutes or until they are nice and brown and caramelized. Remove from the oven and let cool for a few minutes.

4 Once the onions and garlic have cooled a little, put them in a food processor. Puree them until they are a pretty smooth paste. Set aside. 
5 Now, start the cheese sauce. In a large pot, heat the vegan butter on medium.
