Ingredients for Harissa Roasted Cauliflower Steaks

Here’s what you’ll need for this flavorful dish:

1 large head of cauliflower: Fresh is best, but if you’re in a pinch, frozen works too! Just make sure to thaw them out beforehand.
3 tablespoons harissa paste: This is what gives your steaks that fiery kick! It’s aromatic and delicious. You can find it in the international aisle at your grocery store or make your own if you’re feeling adventurous.
2 tablespoons olive oil: This helps with roasting and gives the steaks a lovely crisp. Feel free to swap half for melted coconut oil for a different flavor twist!
Salt to taste: A couple pinches of salt will do! Adjust to your liking.
Pepper to taste: Freshly ground pepper adds extra zing!
Lemon wedges for serving: Squeeze over the top for an amazing brightness.
Fresh herbs (such as cilantro or parsley) for garnish: It adds a fresh touch to finish the dish.

How to Make Harissa Roasted Cauliflower Steaks

Ready to dive in? Let’s get cooking!

Preheat the oven to 425°F (220°C). Turn that oven on while you prep your cauliflower, this will ensure it’s nice and hot when the steaks go in.
Prepare the cauliflower: Remove the leaves from the cauliflower and slice it into thick steaks, about 1 inch thick. You can save the leftover florets for another recipe or snack on them later!
Mix the harissa sauce: In a bowl, mix together your harissa paste, olive oil, a couple pinches of salt, and a dash of pepper. The smell? It’s going to be amazing.
Brush the mixture: Using a basting brush (or your hands!), coat both sides of the cauliflower steaks generously with that harissa mixture. Don’t be shy, make sure each steak is covered with all that flavor!
Roast the steaks: Place your beautifully prepared steaks on a baking sheet lined with parchment paper. Pop them in the oven and roast for 25-30 minutes. You’ll want to flip them halfway through. They’re done when they’re golden and charred at the edges, so keep an eye on them!
Serve hot: Serve immediately with fresh lemon wedges and a sprinkle of your chosen herbs. Honestly, it’s just so simple but feels fancy!

Serving Suggestions

These Harissa Roasted Cauliflower Steaks are super versatile. Here are a few ideas on how to serve them:

On a bed of quinoa or couscous: The nutty flavors of grains pair beautifully with the spicy steaks.
With a side salad: Crisp greens with lemon vinaigrette complement the warmth of the dish.
As a centerpiece for meatless Monday: These steaks can turn any dinner into a soul-satisfying experience.
Leftovers? They reheat beautifully! Toss any extras into a wrap for a quick lunch or crumble over a grain bowl for dinner the next night.

Storage Tips

How long do they keep? If you have leftovers (which I doubt!), keep them in an airtight container in the refrigerator for up to 4 days.
Reheating instructions: Simply pop them back in the oven at 350°F for about 10-15 minutes or microwave them, just be careful not to make them mushy!
Freezer friendly? I’d recommend against freezing these. The texture can get a bit funky when thawed and reheated.
