Cook the spaghetti squash using your preferred method (we cut off the ends, poke all over with a fork, then microwave for 20 minutes) then remove the noodle-like strands, place the strands in a colander to drain the excess moisture then set-aside.
Heat the butter over medium-high heat in a large 10.5″ cast iron skillet. Add the onion, garlic, and thyme to the skillet and cook about 1 minute, just until fragrant.
Add in the drained spaghetti squash and stir to combine. Stir in the sour cream and half of the parmesan. Simmer for 5 minutes then top with remaining parmesan and transfer to the broiler for 3-5 minutes until the top is golden brown. Top with additional thyme and serve.
