  • 1 medium spaghetti squash
  • 1 medium sweet onion, diced
  • 2 tbsp butter
  • 3/4 cup plain Greek yogurt
  • 2 cloves minced garlic
  • 1 + 1/2 cup sharp white cheddar cheese
  • dash salt, optional
  • 1/2 tsp black pepper



Step 1

Preheat oven to 375.

Microwave squash for about 5 mins to make it easier to cut!
Cut squash lengthwise, scoop out seeds, and place face-down casseroledis with a 1/2 inch of water.
Bake 20-30 mins
**You can cook it till soft in the microwave, takes less time and is just as good**

While squash is baking, caramelize onions.

Heat butter in a large (oven proof pan *also saves a step and you only have to wash 1) and onions to the pan. Cook on medium, stirring frequently, until onions are brown and caramelized. Add garlic and cook for 2-3 minutes. Stir in spices.

Once the squash has cooled some and you can handle it, scrape the flesh out with a fork.

Stir the greek yogurt into the onions and then add the squash and 1 cup of the cheese. Stir until combined.

Top with the remaining 1/3 cup cheese and pour into a baking dish. Bake 30 minutes. If the top isn’t browned, broil for a few minutes until the cheese is brown and bubbly
