Step-by-Step Instructions
Step 1: Prepare the Oven
Preheat your oven to 400°F (200°C).
Lightly grease a 9×13-inch baking dish.
Step 2: Roast the Cauliflower
Place the cauliflower florets on a baking sheet.
Drizzle with olive oil.
Season with salt and pepper.
Roast for 15 minutes, until slightly tender and beginning to brown.
Step 3: Season the Steak
Pat the steak dry using paper towels.
Season with salt, pepper, garlic powder, and smoked paprika.
Toss until evenly coated.
Step 4: Sear the Steak
Heat olive oil in a large skillet over medium-high heat.
Sear the steak cubes for 2–3 minutes per side.
Do not cook completely—the steak will finish baking.
Transfer to a plate.
Step 5: Make the Garlic Butter Sauce
Reduce heat to medium.
Add butter.
Stir in minced garlic and cook for 30 seconds.
Add Worcestershire sauce, Italian seasoning, and beef broth.
Simmer for 2–3 minutes.
Mix in chopped parsley.
Step 6: Assemble
Place roasted cauliflower into the prepared baking dish.
Spread the steak cubes evenly over the cauliflower.
Pour the garlic butter sauce over everything.
Sprinkle mozzarella and Parmesan cheese evenly on top.
Step 7: Bake
Bake uncovered for 15–18 minutes, until the cheese melts and becomes bubbly.
For a golden finish, broil for 2–3 minutes.
Step 8: Garnish and Serve
Sprinkle with fresh parsley.
Serve immediately while hot.
Best Tips

Roast the cauliflower first to prevent excess moisture.
