  • 2 cups broccoli florets
  • 2 cups cauliflower florets
  • 1 cup kohlrabi or parsnips peeled and diced
  • 2 cups mushrooms sliced
  • 8 oz hot Italian turkey sausage casings removed
  • 2 Tablespoons olive oil
  • salt and pepper to taste
  • 2 cups low sodium chicken stock
  • 1/2 cup of milk
  • 1/4 cup flour
  • 3/4 cup shredded Gruyere cheese
  • 2 Tablespoons butter
  • 1 cup panko breadcrumbs


  1. Preheat oven to 350 degrees
  2. Toss broccoli, cauliflower, kohlrabi, and mushrooms in olive oil and season with salt and pepper. Spread on a baking sheet and roast for 20 minutes until vegetables begin to brown and soften.
  3. Meanwhile, cook sausage in a skillet over medium high heat until browned. Drain and set aside.
  4. In a small saucepan bring chicken stock and milk to a boil. Reduce to a simmer and whisk in flour to form a thick sauce. Add Gruyere whisking constantly until smooth and fully combined. If the sauce seems too thick, add a little bit more milk.
  5. Stir together roasted vegetables, sausage and cheese sauce. Pour into a greased casserole dish.
  6. Melt butter in a small skillet. Add panko breadcrumbs and stir constantly until browned. Top casserole with toasted breadcrumbs.
  7. Bake casserole, uncovered for 25 minutes until bubbly.
