First, preheat your oven to 400F. Cut the spaghetti squash in half lengthwise, then scoop out the seeds & guts. Spray or brush the inside of each half with oil, then season with kosher salt & black pepper. Place cut-side-down onto a baking sheet, and use a fork to pierce holes all over the top of the spaghetti squash. Transfer to the oven and bake until tender, about 25-35 minutes.
1 small spaghetti squash, cooking spray, kosher salt & black pepper
Pat chicken breasts dry, then season on both sides with kosher salt & black pepper. Add flour to a shallow, wide bowl and dredge both sides of the chicken breasts, then gently shake to remove any excess. Set aside.
1 lb boneless, skinless chicken breast, ½ cup gluten free 1-to-1 flour
Bring a large pan to medium-high heat. Once hot, add 2 tbsp of oil. Then, add chicken, making sure there isn't any overlap -- depending on the size of your pan & chicken, you may have to do this in two batches, adding more oil as needed. Cook until lightly golden on each side, about 3 minutes per side. Transfer chicken to a plate and set aside.
3 tbsp olive oil
Reduce heat to medium. Add 1 tbsp of butter and 1 tbsp of oil. Once butter has melted, add mushrooms and spread out evenly in the pan. Let cook, undisturbed, for 3-4 minutes. Then, add shallots, season with kosher salt & stir. Sauté for 3 more minutes. Add in garlic and thyme and sauté until fragrant, 1 more minute.
1 tbsp unsalted butter, 8 oz baby bella mushrooms, 2 shallots, 3 garlic cloves, ½ tbsp fresh chopped thyme
Deglaze the pan with marsala wine, scraping up all the browned bits at the bottom of the pan. Then, add in the chicken broth, heavy cream & more salt & pepper. Stir. Increase the heat to bring the sauce up to a boil, then reduce heat to medium and let simmer for 4-5 minutes. Nestle in the chicken and continue to let the sauce simmer for about 3 more minutes, or until thickened.
¾ cup dry marsala wine, ¾ cup chicken broth, ¾ cup heavy cream
Use a fork to scrape the flesh of the spaghetti squash into strands. Serve chicken marsala along with the spaghetti squash, and garnish with chopped parsley. Enjoy!
