Instructions
- 1
Preheat the oven to 220°C / 425°F. Place the cauliflower on a sheet pan and toss it with 1 tablespoon olive oil, 1/2 teaspoon salt, 1/4 teaspoon black pepper, and the smoked paprika. Roast for 20 to 22 minutes at 220°C / 425°F, stirring halfway through, until golden and tender.
- 2
While the cauliflower roasts, heat a large skillet over medium-high heat. Add the Italian sausage pieces and brown them for 6 to 8 minutes, breaking them up lightly with a spoon, until fully cooked. Transfer to a plate and set aside.
- 3
Reduce the heat to medium. Add the remaining 1 tablespoon olive oil and the butter to the same skillet. When the butter melts, add the sliced fennel and cook for 6 to 8 minutes, stirring, until tender with golden edges.
- 4
Add the minced garlic and fresh thyme leaves to the fennel. Cook for 30 seconds, just until fragrant.
- 5
Pour in the chicken broth and scrape the bottom of the skillet to release the browned bits. Cook for 2 minutes to reduce slightly.
- 6
Stir in the heavy cream, grated Parmesan, green olives, lemon zest, and lemon juice. Cook over medium-low heat for 3 to 4 minutes, stirring, until the sauce is creamy and lightly thickened.
- 7
Return the browned sausage to the skillet along with any accumulated juices. Add the roasted cauliflower as well and toss gently to coat everything in the sauce. Cook 2 minutes more to blend the flavors.
- 8
Taste and adjust with the remaining salt and more black pepper if needed. Turn off the heat, sprinkle with chopped fresh parsley, and serve hot.
Chef tips
For better browning, do not overcrowd the cauliflower on the pan. If the sausage releases a lot of fat, remove some of it before cooking the fennel so the sauce stays balanced.
Substitutions
You can swap the fennel for half-moon zucchini, or use black olives instead of green olives. If you do not have Parmesan, use grated pecorino and adjust the salt since it is saltier.
