3 tablespoons olive oil
½ teaspoon salt
½ teaspoon black pepper
½ teaspoon garlic powder
½ teaspoon paprika
For the Mushroom Gruyère Sauce
2 tablespoons butter
1 tablespoon olive oil
2 cups mushrooms, sliced (button or cremini)
2 cloves garlic, minced
1 cup heavy cream
¾ cup grated Gruyère cheese
¼ cup grated Parmesan cheese
¼ teaspoon salt
¼ teaspoon black pepper
½ teaspoon fresh thyme (optional)

Cracked black pepper
Instructions
Preheat the Oven
Preheat your oven to 400°F (200°C) and line a baking tray with parchment paper.
Prepare the Cauliflower
Remove the outer leaves from the cauliflower and trim the stem so it sits flat while keeping the head intact.
Season the Cauliflower
Place the cauliflower on the baking tray. Drizzle with olive oil and rub it evenly over the surface. Sprinkle salt, pepper, garlic powder, and paprika.
Roast the Cauliflower
Roast for 40–45 minutes, turning halfway through, until the cauliflower is golden brown and tender when pierced with a knife.
Cook the Mushrooms
While the cauliflower roasts, heat butter and olive oil in a skillet over medium heat. Add the sliced mushrooms and cook for about 5–6 minutes until softened and slightly golden.
Add Garlic
Stir in the minced garlic and cook for about 30 seconds until fragrant.
Add Cream
Pour in the heavy cream and bring to a gentle simmer.
Add Cheese
Stir in the grated Gruyère and Parmesan cheese. Mix until the cheese melts and the sauce becomes smooth and creamy.
Season the Sauce
Add salt, pepper, and thyme if using. Stir until well combined.
Serve
Place the roasted cauliflower on a serving plate and pour the silky mushroom Gruyère sauce over the top. Garnish with parsley and extra cheese before serving.
