Instructions

Step 1
Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper to ensure the steaks don't stick.
Step 2
Remove the leaves and trim the stems of the cauliflower, keeping the heads intact. Carefully slice each head into 3-4 thick steaks (about 3/4 inch thick). Save any loose florets that fall off for roasting alongside.
Step 3
Place the cauliflower steaks and loose florets onto the prepared baking sheet in a single layer.
Step 4
In a small mixing bowl, combine the olive oil and minced garlic. Use a basting brush to coat both sides of the cauliflower steaks evenly with the mixture.
Step 5
In another bowl, mix the Parmesan cheese, smoked paprika, dried oregano, sea salt, and black pepper. Sprinkle this seasoning evenly over the tops of the cauliflower steaks.
Step 6
Roast in the oven for 25–30 minutes until the cauliflower is golden and the edges are crisp. Flip the steaks halfway through the cooking time to ensure even roasting.
Step 7
Remove from the oven and sprinkle with fresh chopped parsley before serving, if desired.

Zusatztipps für die Zubereitung

To get the best results, use a sharp knife to cut through the core of the cauliflower, which helps keep the steaks together. Using a large baking sheet and parchment paper is essential for achieving that perfect golden crust without the cauliflower sticking. If you have any small florets left over, don't discard them; they become extra crispy and delicious when roasted with the steaks.

Varianten und Anpassungen

If you prefer a dairy-free or vegan version of this recipe, you can easily substitute the Parmesan cheese with nutritional yeast. This will still provide a savory, cheesy flavor profile while keeping the dish entirely plant-based. You can also experiment with different herbs like dried thyme or rosemary for a variation in flavor.

Serviervorschläge

These cauliflower steaks are incredibly versatile. For a satisfying vegetarian main dish, serve them topped with a fried egg. If you are looking for a side dish, they pair exceptionally well with grilled chicken or a juicy steak. The savory Parmesan crust makes them a hit at any dinner table.

Recipe Questions

What makes cauliflower steaks different from florets?

Cauliflower steaks are thick vertical slices cut from the whole head, creating substantial portions that hold their shape during roasting. This technique yields a meatier texture and allows for better browning compared to individual florets.

How do I get the crispiest edges?

Preheat your oven thoroughly to 425°F and avoid overcrowding the baking sheet. Flip the steaks halfway through cooking and consider finishing under the broiler for 1-2 minutes if you want extra crunch.

Can I make this dairy-free?

Yes, substitute nutritional yeast for the Parmesan cheese. It provides a similar savory, umami flavor and cheesy texture while keeping the dish dairy-free and vegan.

What do I do with leftover florets?

Roast the loose florets alongside the steaks. They'll cook slightly faster, so remove them first if they're getting too dark, or toss them separately with the same seasoning blend.

How should I store and reheat leftovers?

Store in an airtight container in the refrigerator for up to 4 days. Reheat in a 400°F oven for 10-12 minutes to restore crispiness—avoid the microwave as it will make the cauliflower soggy.

Can I prepare these ahead of time?

Slice and season the cauliflower up to 24 hours in advance, keeping it refrigerated. Roast just before serving for the best texture and flavor.
