- 1 container Kite Hill cream cheese
- 1 tbsp ghee

- Step 3: Drizzle olive oil inside the squash halves and sprinkle with salt and pepper.

- Step 11: Transfer the mixture to the prepared casserole dish and spread evenly.
- Step 12: Bake for 30 to 40 minutes at 350°F until the casserole is bubbling and heated through.
Tips & Variations
