Cooking Roasted Cauliflower with Red Peppers, Green Olives, and Pine Nuts: The Process

Step 1: Preheat the Oven
Start by preheating your oven to 425°F (220°C). A hot oven is crucial for achieving that beautiful caramelization on the vegetables.
Step 2: Prepare the Vegetables
While the oven is heating, wash and cut the cauliflower into small, uniform pieces. This ensures even cooking. Next, take your red bell pepper, remove the stem and seeds, and dice it into 1/2 inch pieces.
Step 3: Toss with Olive Oil
In a large mixing bowl, combine the cauliflower and red bell pepper. Drizzle with 2 tablespoons of olive oil and season generously with salt and freshly ground black pepper. Toss everything together until the vegetables are well-coated.
Step 4: Spread on Baking Sheet
Transfer the seasoned vegetables onto a large baking sheet in a single layer. Make sure not to overcrowd the pan; this will help them roast evenly and attain that lovely golden color.
Step 5: Roast the Vegetables
Place the baking sheet in the preheated oven and roast for about 20-25 minutes. Halfway through, give them a good stir to ensure even roasting. You’re looking for a golden-brown color and tender texture.
Step 6: Add Pine Nuts and Olives
Once the cauliflower and red peppers are nearly done, remove the baking sheet from the oven. Sprinkle the pine nuts and sliced green olives over the top, then return it to the oven for an additional 5-7 minutes. This allows the pine nuts to toast lightly and the olives to warm up.
Step 7: Finish with Capers and Parsley
After roasting, take the baking sheet out and sprinkle the capers over the vegetables. If you’re using parsley, chop it finely and sprinkle it for a burst of color and freshness. Toss gently to combine.
Step 8: Serve with Lemon
For an extra zing, squeeze some fresh lemon juice over the roasted vegetables just before serving. This brightens up the dish beautifully.
Variations by Season

- Spring: Add some asparagus or snap peas for a fresh crunch.
- Summer: Incorporate zucchini or cherry tomatoes for a burst of color.
- Fall: Mix in sweet potatoes or butternut squash for a heartier dish.
- Winter: Try adding Brussels sprouts or kale for extra nutrition.
If You’re Curious
Roasting vegetables not only enhances their flavors but also makes them easier to digest. This dish is naturally vegan and gluten-free, making it suitable for various dietary preferences. Feel free to experiment with different herbs and spices, such as thyme or smoked paprika, to customize the flavor profile to your liking.
Shelf Life & Storage
This roasted cauliflower dish is best enjoyed fresh, but if you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave, but be aware that reheating may soften the vegetables slightly.
Troubleshooting Q&A
What should I do if my cauliflower is soggy?
If your cauliflower is soggy, it may not have been roasted at a high enough temperature or was overcrowded on the baking sheet. Make sure to roast at a high temperature and spread the vegetables out evenly.
Can I use different kinds of olives?
Absolutely! While green olives work beautifully in this dish, feel free to use black olives or even a mix of both for a different flavor profile.
What if I don’t have pine nuts?
If pine nuts aren’t available, you can substitute them with walnuts, almonds, or sunflower seeds. Each will add a unique flavor and texture to the dish.
Can I make this dish ahead of time?
While this dish is best served fresh, you can prep the vegetables ahead of time and store them in the refrigerator. Just roast them right before serving for optimal taste and texture.
