In a pan, cook the chopped onion with some sage in olive oil until soft and clear-looking. Take a mixing bowl and combine ricotta, the pumpkin mash, 1/3 cup cheese, garlic, nutmeg, salt, and pepper. Once the onion mixture is done, mix it in too. Stir well!

Melt butter in a pan on medium heat. Keep stirring until it barely changes color to brown. Add chopped sage, give it a stir for the smell to kick in, and toss in the flour. Stir for one minute. While whisking constantly, pour in half the cream and wait until it thickens. Stir the rest of the cream in and season lightly with salt and pepper. Keep whisking until the sauce is nice and thick.
