Description

A delightful gratin of broccoli and cauliflower mixed with caramelized sausage in a rich, cheesy custard, topped with a crispy finish.


Ingredients

Scale
  • 3 cups broccoli florets, cut into 1 inch pieces
  • 3 cups cauliflower florets, par-cooked
  • 12 oz Italian or smoked sausage, crumbled
  • 1 cup heavy cream
  • 4 oz cream cheese, softened
  • 1 large egg, lightly beaten
  • 1 cup Gruyère or sharp cheddar, finely shredded (reserve ¼ cup for topping)
  • 2 tbsp unsalted butter, room temperature
  • 1 tsp Dijon mustard
  • 2 garlic cloves, minced
  • 1 tbsp fresh parsley, finely chopped
  • Salt and freshly ground black pepper, to taste
  • ¼ cup grated Parmesan
  • ⅔ cup crushed pork rinds or almond meal
  • A few pinches of smoked paprika or fresh thyme leaves for garnish

Instructions

  1. Preheat the oven to 375°F (190°C) and butter a 9×9 inch baking dish.
  2. Blanch broccoli and cauliflower in salted boiling water for 2–3 minutes, then transfer to an ice bath and drain well.
  3. In a skillet, brown the crumbled sausage for 6–8 minutes until caramelized, deglazing the pan as needed.
  4. In a bowl, whisk together heavy cream, softened cream cheese, beaten egg, Dijon mustard, minced garlic, parsley, salt, and pepper until smooth.
  5. Fold in ¾ cup shredded cheese and mix well.
  6. Toss the drained florets and sausage with the creamy mixture and transfer to the baking dish, smoothing the surface.
  7. Combine remaining shredded cheese with crushed pork rinds or almond meal, sprinkle over the gratin, and dot with butter and a dusting of smoked paprika or thyme.
  8. Bake for 20–25 minutes until bubbling and golden brown. Broil for an additional 1–2 minutes for a crispy top.
  9. Let rest for 5–10 minutes before serving.

Notes

For a luxurious upgrade, drizzle with white truffle oil after baking. Resting time improves cutting and flavor concentration.
