The Method for Roasted Cauliflower and Red Peppers with Olives

Now, let’s dive into the step-by-step process to create this delicious Roasted Cauliflower and Red Peppers with Olives.
Step 1: Preheat Your Oven
Preheat your oven to 425°F (220°C). A hot oven is key to achieving that perfect roasted flavor.
Step 2: Prepare the Vegetables
Wash and cut the cauliflower into bite-sized florets. If using a red bell pepper, remove the stem and seeds, then slice it into thin strips. If you prefer cherry tomatoes, halve them instead. Slice the cremini mushrooms for added texture and flavor.
Step 3: Combine Ingredients
In a large mixing bowl, combine the cauliflower florets, sliced red bell pepper (or halved cherry tomatoes), sliced cremini mushrooms, green olives, and capers. Drizzle with the extra virgin olive oil and freshly squeezed lemon juice. Sprinkle with kosher salt and freshly ground black pepper.
Step 4: Toss and Spread
Toss the mixture well to ensure all the vegetables are evenly coated with the oil and seasonings. Spread the mixture out in a single layer on your baking sheet. This helps achieve that coveted roasted texture.
Step 5: Roast the Vegetables
Place the baking sheet in the preheated oven and roast for about 25-30 minutes, or until the cauliflower is tender and golden brown. Halfway through the roasting time, give the vegetables a gentle toss to ensure even cooking.
Step 6: Garnish and Serve
Once roasted, remove the baking sheet from the oven. If desired, sprinkle with chopped parsley for a fresh finish. Serve warm and enjoy the incredible flavors of your Roasted Cauliflower and Red Peppers with Olives!
