Preheat oven to 425, grease a large baking sheet, set aside. Rinse the broccolini, transfer to a mixing bowl toss in olive oil, salt and pepper. Arrange in a single layer on the prepared baking sheet, bake at 425 for 15-20 minutes until tender.
In a large saute pan, melt butter over medium high heat, add in the minced shallot and saute until fragrant. Add in the paprika, cayenne pepper, and chili powder, stir to combine. Add in the raw walnuts and saute 56 minutes until warmed and fragrant.
Fry the bacon and give it a rough chop. Transfer the roasted broccolini to a serving platter. Top with the spiced walnuts, chopped bacon, and drizzle the remaining butter sauce over the top. Serve and enjoy!
