Ingredients

Scale

Main Ingredients:

  • 2 pounds (0.9 kilograms) butternut squash, peeled and cubed into medium-size chunks
  • ½ pound (0.23 kilograms) sweet Italian sausage, casings removed and crumbled
  • 2 Honeycrisp apples, peeled, cored, and cubed into larger chunks

Vegetables and Herbs:

  • 2 small fennel bulbs, cored and thinly sliced
  • 1 onion, quartered and thinly sliced
  • ½ teaspoon ground sage
  • 1 ½ teaspoons Herbes de Provence
  • Fresh sage leaves (fresh or fried), for garnish

Seasonings and Cheese:

  • Olive oil
  • Salt and black pepper, to taste
  • 2 tablespoons (30 milliliters) pure maple syrup, divided
  • 1 cup grated Gruyere cheese

Instructions

  1. Prepare the oven by heating to 425°F and line a baking sheet with foil, lightly misting with cooking spray.
  2. Cube butternut squash and apples, then toss in a large bowl with olive oil, salt, pepper, maple syrup, ground sage, and Herbes de Provence to ensure even coating.
  3. Spread the seasoned mixture onto the prepared baking sheet, roasting for 35 minutes and stirring periodically until squash becomes tender and develops a golden color.
  4. In a large skillet, cook sweet Italian sausage over medium-high heat until browned and fully cooked, then set aside.
  5. Using the same skillet, sauté fennel and onion until they caramelize and develop a jammy texture, approximately 10-12 minutes.
  6. Combine the roasted squash and apples with the sausage, fennel, and onion mixture, adding an additional tablespoon of maple syrup and adjusting seasonings to taste.
  7. Transfer the combined ingredients to a 9×13 baking dish and generously sprinkle with grated Gruyere cheese.
  8. Switch oven to broil and place the casserole underneath until cheese melts and turns golden-brown.
  9. Create a crispy sage garnish by quickly frying sage leaves in hot olive oil for approximately 20 seconds, then drain on paper towels and lightly salt.
  10. Finish the dish by scattering the fried sage leaves (or fresh alternatives) over the casserole and serve immediately while warm.
