# Method:

01 - Preheat your oven to 375°F. Lightly grease a 9x13-inch baking dish with cooking spray or olive oil.
02 - In a large skillet, heat olive oil over medium heat. Add the diced onion and cook until translucent, about 5 minutes.
03 - Add minced garlic and cook for 1 minute, until fragrant.
04 - Increase the heat slightly, add the Italian sausage, and cook until browned and cooked through, breaking it apart with a wooden spoon, about 7–10 minutes.
05 - Add the butternut squash to the skillet. Stir in dried thyme, dried sage, paprika, salt, and pepper. Cook for 5–7 minutes, stirring occasionally, until the squash starts to soften.
06 - Add the baby spinach and cooked quinoa, stirring until the spinach wilts.
07 - Pour in the chicken or vegetable broth and simmer for 3–4 minutes.
08 - Transfer the mixture to the prepared baking dish. Spread evenly and top with shredded mozzarella and grated Parmesan cheese.
09 - Cover with aluminum foil and bake in the preheated oven for 25 minutes.
10 - Remove the foil and bake for an additional 15–20 minutes, or until the cheese is bubbly and golden brown.
11 - Remove from the oven and let cool for 5 minutes. Garnish with fresh parsley before serving.

# Expert Advice:

01 -
  • Everything cooks in one pan before hitting the oven, meaning minimal cleanup and maximum flavor development
  • The combination of sweet roasted squash and savory Italian sausage creates this perfect balance that keeps everyone coming back for seconds
02 -
  • Cutting butternut squash can be tricky, so microwave the whole squash for 2 to 3 minutes first to soften it slightly
  • Letting the casserole rest for 5 minutes after baking makes serving much cleaner and helps the flavors settle
03 -
  • Always check that your sausage and broth are certified gluten-free if that is a concern for you or your guests
  • Grating your own Parmesan rather than buying pre-grated makes a huge difference in how well it melts and tastes
