Separate the thicker portion of stems from the broccoli rabe leaves and florets. Discard the stems or save them for another recipe. Steam the broccoli rabe leaves and florets to soften, about three minutes. Drain and set aside. Start the pasta in a separate pot and cook until al dente.
Return the sausage to the pan with the broccoli rabe and add the tomato paste and chopped shallot. Cook on medium-low heat while mixing for another 2 minutes. Then, add the chicken broth and bring to a simmer.
Reserve two-thirds of a cup of the pasta water and strain the orecchiette. Add the orecchiette and pasta water with the tomatoes to the pan and mix all ingredients thoroughly.
Transfer the pan to the oven and bake at 350 for 15 minutes.
Remove from the oven and stir or transfer to a serving bowl. Then, deposit the Ricotta cheese in the middle.
Serve with the grated cheese and more FGBP on the side.
