Ingredients

(Original recipe yields 6 servings)
- 1 lb (450g) Italian sausage (mild or spicy, based on preference)
- 2 tbsp olive oil
- 1 large onion, chopped
- 2 carrots, peeled and sliced
- 2 parsnips, peeled and sliced
- 1 small butternut squash, peeled and cubed
- 2 cloves garlic, minced
- 1 cup frozen peas

- 1 (15-ounce) can diced tomatoes
- 1 cup chicken or vegetable broth
- 1 tsp dried thyme
- 1 tsp smoked paprika
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1 cup shredded cheddar cheese
- 1/2 cup grated Parmesan cheese
- 1/4 cup breadcrumbs (optional, for crunch)

Directions

- Preheat the Oven:
Preheat your oven to 375ยฐF (190ยฐC). Lightly grease a 9×13-inch baking dish with nonstick cooking spray or olive oil. - Cook the Sausage:
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the Italian sausage and cook until browned, breaking it into small pieces with a wooden spoon. Remove the sausage and set aside. - Sautรฉ the Vegetables:
In the same skillet, add the remaining olive oil. Sautรฉ the onion, carrots, parsnips, and butternut squash for 8-10 minutes, or until the vegetables begin to soften. Add the minced garlic and cook for 1 more minute. - Combine Ingredients:
In a large mixing bowl, combine the cooked sausage, sautรฉed vegetables, frozen peas, frozen corn, diced tomatoes, chicken broth, thyme, smoked paprika, salt, and pepper. Mix well. - Assemble the Casserole:
Transfer the mixture to the prepared baking dish. Sprinkle the shredded cheddar cheese and grated Parmesan evenly over the top. For extra crunch, add a layer of breadcrumbs. - Bake:
Cover the dish with aluminum foil and bake for 30 minutes. Remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and golden brown. - Garnish and Serve:
Remove from the oven and let cool for 5 minutes. Garnish with fresh parsley or rosemary before serving.
