Step‑by‑Step Instructions for Cauliflower Steak Sandwich
Step 1: Preheat the Oven
Begin by preheating your oven to 200°C (400°F). This is essential for achieving that perfect golden exterior on your cauliflower steaks. Set your timer for accuracy, as a properly heated oven ensures even roasting. While the oven warms up, gather your ingredients and equipment to streamline the cooking process.
Step 2: Prepare the Cauliflower
Take a fresh cauliflower and carefully slice it into 1.5 cm (0.6 inch) thick “steaks.” Make sure to keep the core intact as it helps maintain their shape during cooking. You should yield about three hearty steaks. This step is crucial for ensuring that each cauliflower steak has the right thickness for even roasting.
Step 3: Season the Steaks
Place the cauliflower steaks on a baking tray lined with parchment paper for easy cleanup. Drizzle them generously with olive oil, then coat with Prego sauce, and season with salt and pepper. Use a brush or your hands to rub the mixture evenly over both sides of the steaks, ensuring they are well covered and ready for roasting.
Step 4: Roast the Cauliflower
Slide the baking tray into your preheated oven and roast the cauliflower steaks for 30 minutes. Halfway through the cooking time, carefully flip each steak to achieve a beautiful, even browning on both sides. Look for a golden-brown color and a tender yet slightly crisp texture to indicate they are perfectly done.
Step 5: Assemble the Sandwich
Once the cauliflower steaks are roasted to perfection, remove them from the oven and let them cool for a minute. Slice your Portuguese rolls open and place a roasted cauliflower steak on each roll. For an extra flavor boost, drizzle additional Prego sauce over the top before closing the sandwich.
Step 6: Serve and Enjoy
Your delicious cauliflower steak sandwiches are now ready to be served! Cut the sandwiches in half if you’d like and pair them with a fresh green salad or even some crispy air-fried potato wedges. These satisfying sandwiches showcase a delightful balance of flavors and textures that are sure to impress everyone at the table.

Make Ahead Options
These Cauliflower Steak Sandwiches are perfect for meal prep enthusiasts! You can slice and season the cauliflower steaks up to 24 hours in advance, allowing the flavors to meld together before roasting. Simply store the seasoned steaks in an airtight container in the refrigerator. When you’re ready to enjoy your meal, preheat the oven and roast the cauliflower steaks as directed, ensuring you flip them halfway for even cooking. To maintain quality, avoid assembling the sandwiches until just before serving to keep the rolls fresh and prevent sogginess. With these make-ahead tips, you’ll have a delicious dinner ready with minimal effort!
