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

- 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.
