Growing up, I loved potatoes au gratin and scalloped potatoes. That was even the highly processed, “just add water and powdered cheese” varieties that came from a box. In the constant search to replace those starchy potatoes we all love, spaghetti squash has proven to be a worthy opponent. Plus, this recipe has bacon and we all know that bacon makes everything better. Now I can look forward to a low carb, gluten free version of a childhood favorite.

Ingredients
Scale
- 1 large spaghetti squash
- 2 tablespoons olive oil
- 2 tablespoons butter
- 3 cloves garlic, minced
- 1 small onion, thinly sliced
- sea salt and black pepper, to taste
- 8 slices bacon, cooked crisp and crumbled
- 1 ½ cups sour cream
- 2 cups shredded sharp cheddar cheese

Instructions
- Preheat oven to 400°F Line a rimmed baking sheet with parchment paper or a silpat. Cut spaghetti squash in half crosswise and scrape out the seeds. Drizzle olive oil over spaghetti squash and sprinkle with salt and pepper. Place cut side down on prepared baking sheet. Bake for 40 minutes or until the spaghetti squash is tender and the shreds easily pull away from the skin.
- While the squash is roasting, heat a large skillet over medium heat. To the pan add the butter, garlic, onions, salt and pepper. Cook until the onions are lightly caramelized.
- Once the squash has cooled, use a fork to scrape the flesh into a large mixing bowl. To the bowl, add the onions, bacon, sour cream, cheddar cheese, and Parmesan cheese. Mix until all ingredients are well incorporated. Transfer to a casserole dish.
- Reduce the oven temperature to 350° Bake for an additional 20 minutes.
