Preheat oven to 450 F and wrap the red beets in foil and the golden beets in another sheet of foil. Roast until very tender, about 1 hour - 1 1/2 hours. Peel and dice.
Starting with the golden beets, transfer to a food processor and puree until fairly smooth. Add in 1/4 cup ricotta and puree until very smooth. Then add 1 tbsp egg, 1/4 cup parmesan cheese, 1/2 cup plus 2 tbsp flour, pinch nutmeg, 1/8 tsp cinnamon, 1/4 tsp salt and 1/8 tsp pepper. Pulse just until combined. If the dough is way too wet to work with you can add more flour, one tablespoon at a time.
Put flour on your surface and grab about 1/4 cup worth of dough. Roll it into a log shape then cut into 1 cm little pieces. Don't worry about them all being the same, I prefer them to be a bit assymetrical and unique. Set the golden gnocchi aside on a baking sheet lined with a silpat.
Rinse out the food processor and do the same with the red beets. Place them on a separate baking sheet.
Bring a pot of salted water to a boil and add in the golden beet gnocchi. They will only take a few minutes, and when they float, they're done. Transfer the cooked gnocchi to the baking sheet again.
Drain and refill the pot with fresh salted water, then cook the red beet gnocchi the same.
Meanwhile, to a large nonstick skillet heat one tablespoon of oil over medium heat. Add the stems of the chard and saute for 2 minutes until slightly softened. Add in the leaves and toss just until wilted. Add the balsamic and season with salt and pepper. Transfer to a plate or bowl.
Add the additional tablespoon of oil to the pan and add in the gnocchi. Cook until browned and caramelized, then add back the chard. Turn off the heat and let it sit in the pan to stay warm.
Finally, using a stainless steel pan (so you can see the colour change better), melt the butter over medium heat. Once it foams, add sage and cook until crisp and fragrant. Remove sage to a plate and return frying pan to stove. Allow the milk solids to begin to brown and the butter to become fragrant and nutty. Scrape along the bottom to prevent the solids from sticking and burning. Once fragrant and nutty, add a pinch each of salt and pepper and immediately remove from the heat.
Transfer the gnocchi and chard to a serving plate and drizzle with the browned butter. Top with extra parmesan, crushed walnuts and the crispy sage. Enjoy!
